Preliminary Study of How Powder Size Distribution (PSD) Affects The Packing
density On Powder Bed Additive Manufacturing Using High Performance Cloud
Computing
Time: 9:15
Author(s): Don Kim
Faculty Mentor(s): Shokufeh Mirzaei
Abstract: In metal 3D printing (additive manufacturing), there have been research that showed that
packing density of virgin metal powder particles directly affects the quality of 3D printed parts. High
packing density of metal powder in each layer of laser sintering process would yield lesser chance of
porosity, higher material strength, reduced hairline cracks, and smaller chance of materials fractures
than with a powder layer of low packing density.
The goal of this study is to understand how varying particle size distribution can affect the packing
density of metal powder particles, and eventually study how to optimize particle size distribution on a
given set of size constraints using computer programming and scale model building. In computer
programming, a 2-D programming simulation was built that can connect to commercially available cloud
computing servers using computer language CUDA. In scale model building stainless steel balls of
varying diameter sizes were used to represent scaled particles and its packing density was measured to
validate the 2-D programming.
Artificial Intelligence: Principles, Technologies, Breakthroughs, Impacts and
Challenges

Abstract: The twenty-first century has witnessed a tremendous growth in computing technology.
Artificial Intelligence is one of the most important aspects of Information Technology that has received a
boost due to this growth. Computers and their accessories have become increasingly cheaper, allowing
more people to participate in the evolution of the technology. The interest to develop machines with
human-like thinking capabilities began in the mid-twentieth century with the invention of the Turing
machine. Since then, engineers, scientists, and software programmers have successfully created
programs and algorithms that enable machines to act autonomously. The future presents a vast array of
possibilities, mainly spurred by advances in technology and contribution to the field. An often asked
question is whether future AI will be capable of developing sentient thoughts. This research explores the
principles, supporting technologies, breakthroughs, and impacts of AI technology in modern society.
Unmanned Aerial Vehicles with Multispectral Technology for Growth Analysis of
Lettuce
Time: 9:45
Author(s): Joseph Wolf
Faculty Mentor(s): Subodh Bhandari
Abstract: The focus of this study is to investigate the viability of Unmanned Aerial Vehicle (UAV)-based
remote sensing and machine learning techniques in the estimation of crop biomass and plant height in a
lettuce crop. The main advantage of UAV-based remote sensing is the immediate
availability of high resolution data. Near infrared (NIR) images obtained using remote sensing
techniques help determine crop performances and stresses of a large area in a short period of
time. This in turn helps to optimize the amount of water, fertilizers, and pesticides using site-specific
management of crops. However, for widespread usage of these techniques by the end
users, the accuracy of remote sensing data must be validated using proven ground-based
methods. Equally important is the reduction in the overall cost associated with these techniques.
UAVs equipped with multispectral sensors and digital cameras were flown over lettuce plots at
Cal Poly Pomona's Spadra farm. Different rows of lettuce plots were subjected to different levels
of water and nitrogen treatments. The soil moisture and nitrogen levels were determined prior to
beginning the study. The multispectral images were used in the determination of vegetation
indices including a normalized differential vegetation index (NDVI) that provide information on
the health of the plant. Machine learning classifiers are developed using the Red-Green-Blue
(RGB) images. A handheld spectroradiometer, water potential meter, and chlorophyll meter were
used for ground-truthing. Correlations between NDVI, chlorophyll content, and water potential
were analyzed. The developed machine learning algorithm was able to predict plant health to a
great extent. Remote sensing techniques were also demonstrated to provide moderately accurate
estimates of crop biomass and plant height. Importantly, the current study demonstrated that a
significant proportion of water and nitrogen resources may be conserved in the production of lettuce, a
resource-intensive crop. Machine learning techniques, with sufficient validation, have the potential to
provide significantly cheaper solutions to plant health assessment, crop monitoring, and production
inputs.

Water Goes Around Comes Around
Time: 10:15
Author(s): Magdeline Hutton
Faculty Mentor(s): Maryam Shafahi
Abstract: The Environmental Protection Agency (EPA) has estimated that an 8-minute shower results in
the use of 20 gallons of water. Currently, in Cape town, South Africa residents are allotted access to 13
gallons of water per day per individual due to the global water crisis. The 4-year long drought that
California's recently experienced between 2012-2016 should demonstrate the prospect of potential
water scarcity once again. With the apparent increase of insufficient water sources, a need to salvage
and treat water is a necessity. The leather industry presents a unique case; one where its product is
inherently strong, has multiple applications, and serves as a way of recycling for the meat industry while
its process to achieve these benefits is one of the extreme volatile proportion. There stands reason to
seek a method to maintain these benefits and minimize the environmental sacrifice. This is a review on
the major role of leather industry in water pollution.
Collaboration between Multiple Unmanned Aerial Vehicles for Search and
Rescue Missions
Time: 10:30
Author(s): Thomas Elemy, Bryce Satterfield, Michael Doan, Daniel Molina, Joshua Fofrich
Faculty Mentor(s): Subodh Bhandari
Abstract: This presentation talks about using multiple unmanned aerial vehicles (UAVs) for autonomous
search and rescue mission. Three fixed-wing UAVs are equipped with Pixhawk autopilots for
autonomous flight. The autopilots communicate with the onboard computer that processes the data for
increased autonomy including autonomous takeoff and landing. An algorithm has been developed to
communicate between the autopilot and onboard computer. Pixhawk has commands built-in that allows
communication with the flight computer. Each UAV is equipped with different sensors and payloads so
that each UAV performs a different task. This task and payload distribution helps use the agility of small
UAVs for increased mission efficiency. One of the UAVs is equipped with a camera and image processing
system for target recognition. The second UAV is equipped with a payload drop mechanism for dropping
rescue package. The developed algorithms were successfully verified in flight tests. Object identification
and classification using neural networks for the identification of victims is underway. The images taken
by the UAVs are being used to train neural networks for object recognition. An openly available
computer vision software is being used for this purpose. The MATLAB-based open source software
allows for neural network based computer vision. The presentation will show the results of flight tests as
well as the initial results of neural network based computer vision for target recognition.
Alternative Technical Concepts Program-Level Standards in Two State
Transportation Agencies
Time: 10:45
Author(s): Alyssa Aulicino
Faculty Mentor(s): Ghada Gad
Abstract: The increased use of Alternative Technical Concepts (ATCs) by Departments of Transportation
(DOTs) has created a need to understand how to implement them at the program level, including issues
like which projects to implement them on, how they are defined, and liability considerations. The
purpose of this paper is, thus, to conduct a comparative analysis of two DOTs Design-Build (DB)
programs to identify ATC aspects common to both and develop a list of project characteristics that
commend ATCs’ inclusion in a DB contract, as well as a set of effective practices found in both. To
achieve this objective, the case studies were conducted on two DOTs with varying levels of experience in
ATC implementation; California Department of Transportation (Caltrans) which implemented ATCs in
2010, and Washington DOT (WSDOT) that started in 2003. Case studies included analyzing the program
and project level processes, and encompassed both interviews and content analysis of the Request for
Proposals, evaluation process, and submitted ATCs. Results show that experienced DOTs developed a
standardized ATC procurement process, including how ATCs are incorporated, manuals, and training
guides that could be further enhanced by the less experienced DOTs project selection decisions. These
experiences could be helpful for DOTs in making decisions on including ATCs in their DB contracts, as
well as best practices that could be implemented in their procurement process.
3D Mapping and Integrated Collision Avoidance for Unmanned Aerial Vehicles
Time: 11:00
Author(s): Thomas Elemy, Josh McGinnis, Joseph Orosco, Eduardo Cadena-Perales
Faculty Mentor(s): Subodh Bhandari
Abstract: This presentation discusses utilizing unmanned aerial vehicles (UAVs) and LiDAR technologies
as a means for creating three-dimensional maps along with allowing for the detection of obstacles so
that mid-air collisions may be avoided. This topic of research has many practical applications with
disaster response being just one of them. Having a UAV safely navigate and produce an updated map of
the affected area will serve as one invaluable piece of information that response teams will have at their
disposal. A DJI S1000 Octocopter has been equipped with a Pixhawk, providing autonomous control of
the UAV. A VLP-16 LiDAR along with an Xsens GPS aided inertial measurement unit (IMU) supply the
data that is processed using an onboard Intel NUC board. The resulting data allows for a three-
dimensional map to be created following post-processing using an Iterative Closest Point (ICP) algorithm
and the CloudCompare software. The UAV was structurally modified to secure a 3D printed LiDAR
mount at a 40˚ inclination which provides optimum results while keeping the center of gravity at an
acceptable position. The open-source application, VeloView, was used for gathering LiDAR data for
testing purposes. Work is currently underway to increase the accuracy of the created 3D maps with the
combined LiDAR and IMU data. In addition, the integration of obstacle avoidance is being researched.
More tests will be conducted using LiDAR and IMU data to increase the accuracy of the generated 3D
maps. Simulated results captured with the VeloView application will be presented.

Synthesis of Nickel Nitrosyl Complexes with Bidentate N-heterocyclic Carbene
Ligands
Time: 9:00
Author(s): Zijie Zhang
Faculty Mentor(s): Chantal Stieber
Abstract: As the level of greenhouse gases is continuously increasing, global warming gets great concern
from the world. Nitrous oxide (N2O), a greenhouse gas that mainly produced from fossil fuel
combustion and human activities, has a warming potential up to 310 times that of carbon dioxide. It has
a significant impact because it can damage the ozone layer, reducing protection from the sun and UV
radiation. While soil micro-organisms such as Geobacillus stearothermophilus, can reduce N2O and
transform it into N2, the rate is not high enough to counteract N2O generation and the mechanism is
unknown. With the aim to understand the enzyme mechanism and develop methods to mitigate N2O,
possible oxidation and reduction mechanisms were studied in nickel nitrosyl complexes. Nickel(0)
complexes with bidentate N-heterocyclic carbene ligands were synthesized and characterized by X-ray
diffractometer. They were then oxidized to nickel(I) nitrosyl cations with the addition of NOBF4 and
NO2BF4. The presence of a new Ni-NO bond and a BF41- counterion was confirmed by infrared
spectroscopy. Future directions will include oxidation, reduction and synthesis of N2O and N2
complexes to understand how N2O can be converted to N2.
Mechanistic Investigation into Molybdenum-Catalyzed Deoxydehydration
Reactions
Time: 9:15
Author(s): Jamie Lam, Nathan Wagner
Faculty Mentor(s): Alex John
Abstract: With the depletion of fossil resources, efforts have been directed toward more sustainable
sources of chemicals; fossil resources are non-renewable and have environmental consequences
accompanying their use, making it imperative to focus on more sustainable options, such as biomass.
Although an ideal alternative due to its derivation as a byproduct of many industrial practices, biomass is
highly functionalized with oxygen-containing functional groups, therefore differentiating it from fossil
resources. One of the reactions that may be used to convert biomass into the desired hydrocarbon
feedstocks is deoxydehydration (DODH). In the past, rhenium (Re) has been used to catalyze the
reaction, but its scarcity and cost render it impractical for industrial use. An alternative to rhenium is
molybdenum (Mo), which is cheaper, but results in less effective catalysis. Our research group
previously investigated a series of molybdenum complexes based on sterically and electronically
modulated ligands to establish structure-function relationships. To gain mechanistic insights regarding
these catalysts and the DODH reaction, trends in substrate efficiency will be discussed, as well as
preliminary findings regarding DODH kinetic studies.
Deoxydehydration Reaction Catalyzed by Dioxomolybdenum Complexes of
Salan Ligands
Time: 9:45
Author(s): Garrit Clabaugh
Faculty Mentor(s): Alex John
Abstract: Currently, our material and energy needs are met primarily using fossil resources.
Petrochemicals, for example, obtained from the refining of crude oil are used as fuel and for making
chemicals/materials. Since fossil resources are present only in finite amounts, a transition from fossil to
other renewable resources is a necessity. In the project, we explore the possibility of using biomass as a
renewable resource. However, biomass such as lignocellulose is highly functionalized (oxygenated) while
fossil resources are mostly hydrocarbons in nature. Techniques used to reduce biomass include
deoxydehydration (DODH), which converts vicinal diols to olefins, and dehydration reactions, which also
converts alcohols into olefins. The most efficient catalysts discovered so far for DODH are based on the
rare transition metal, rhenium (Re). These catalysts give outstanding yields of converting substrates -
which mimic the complexity of biomass- into alkenes, but with a downside of being absurdly expensive.
Molybdenum (Mo) on the other hand is far from scarce and is significantly cheaper than rhenium, with
the downside of decreased yields. We are exploring the potential of using molybdenum complexes
(LMoO2) supported over salan ligands (L) in catalyzing the DODH reaction. More specifically, we want to
see how changing the ligand backbone from (N,N'-H2)LMoO2 to (N,N'-Me2)LMoO2 in these complexes
affects catalytic efficiency.
An Investigation of the Seismic Site Response of the Area Surrounding the New
Student Housing at Cal Poly Pomona Using Spectral Ratio Analysis
Time: 9:30
Author(s): Caleb de Silveira
Faculty Mentor(s): Jascha Polet
Abstract: A seismic investigation of the response parameters of the area near the new student housing
units on the Cal Poly Pomona campus was carried out. Double resonance will occur at a site if the
underlying soil column produces amplification at a specific frequency that matches up with the
resonance of the building itself. Under these conditions, greater motions are more likely to occur during
an earthquake and thus a higher likelihood of damage exists. Resonance period and ground motion
amplification values at five sites around the area of the new student housing units were estimated in
this project.
The study involved deploying five seismometers around the construction site. Ambient noise, which
represents the small continuous ground vibrations present in the environment, was recorded for several
hours and then analyzed using the H/V spectral ratio technique with the Geopsy software to determine
the resonance period and amplification values. This method requires no permit and has no
environmental impact, so it is especially useful in well developed areas. The Site Effects Assessment
using Ambient Excitations (SESAME) project provides guidelines for implementing the technique. Data
was collected in areas selected according to SESAME guidelines. The reliability of the curves and the
clarity of the peaks for each site were also determined using the SESAME guidelines.
The construction site overlies alluvial silt with the San Jose Fault trending east-west at the north end.
With the found resonance frequency of ~1 Hz, buildings near 10 stories may experience double
resonance during a seismic event.

How Queer Hip Hop Artists Cultivate a Space on the Internet
Time: 11:00
Author(s): Carissa Tang
Faculty Mentor(s): Kai Smith, Kai Smith
Abstract: By creating a space on the internet, Queer Hip Hop (QHH) artists can expand their audience
and create their own agency in controlling their respective social media. This is highlighted especially in
the political climate of the United States today, where mainstream media paints members of the Queer
[1] community as well as the Hip Hop community in a negative light. Alternative media such as YouTube,
has traditionally been a haven for LGBT+ creators. These media platforms are increasingly filtering and
censoring LGBT+ creators, bringing dire consequences on artists relying on social media to promote their
work, ultimately their livelihood.
This paper analyzes the internet spaces of ten Queer Hip Hop artists by their respective music videos as
well as collecting top comments and other auxiliary data from five of their top individual songs
published online within the past decade [2]. Emphasis will be on the lyrical content as well as the audio-
visual content of the music videos. By doing so, this compilation of primary sources will test the
hypothesis that these individual artists are cultivating a political space of their own.
[1] The term "Queer" is used as an umbrella term for the LGBT+ community.
[2] Individual songs are songs that are performed by the artist and only the artist. Individual songs do
not include collaborations.
Non-Traditional Students in Need of an Academic Support Program
Time: 10:30
Author(s): Dominique Ruvalcaba, Garland Joseph Dryer, Juan Ramon SevillaJulia Alejandra Lozano,
Ludyvina Celeste Hernandez, Evan Anthony Greco
Faculty Mentor(s): Mary Yu Danico
Abstract: The purpose of this study is to identify the needs of non-traditional students and the study will
serve to spread awareness of an underrepresented and disadvantaged population on campus that is in
need of a specific student support program. For the purposes of this study, non-traditional students are
those whom were at the age of twenty-two years old or older at the time of transfering into the
University as either a returning transfer student or newly admitted transfer student from a community
college. These individuals may have faced a myriad of challenges that could have prevented them from
furthering their educational goals. The resocialization of non-traditional college students differs from
entering freshmen and those who transferred in from a community college in two years or less. The
research team hypothesized that the study will serve to gather information and spread awareness of an
underrepresented and disadvantaged population on campus that is in need of a specific student support
program. The research team will gather data by conducting surveys through use of convenience
sampling, random sampling, and snowball sampling undergraduate students currently enrolled at
California State Polytechnic University of Pomona, in Pomona, California.
How the Use of ACO Principles and Healthcare Consumerism Influences Patient-
Centric Care and Medication Decisions
Time: 10:45
Author(s): Jane Y. Kim, Junlin Liang, Erin A. Walton, Nancy Y. Jung
Faculty Mentor(s): Jae Min Jung
Abstract: About 10% of Americans are diabetic, and each year hundreds of billions of dollars are spent
to deal with the disease. Alarmingly, more than one third of Americans are prediabetic and risk being
diagnosed with Type II diabetes, a condition that accounts for 95% of diabetes patients. Since Type II
diabetes requires long-term care, patient-physician interactions and cost control become important
factors. With rising patient consumerism and movement towards efficient healthcare management such
as ACOs (Accountable Care Organizations), which are intended to provide effective yet affordable
services, it is high time to examine the interrelationships among those. Thus, this research sheds light on
the impact of ACO principles on the healthcare provider's patient-centric approach and patient
satisfaction. Moreover, this research intends to investigate how healthcare consumerism might
influence patients' interactions with physicians, their satisfaction, and attitudes and behaviors involving
medication decisions. This research is one of the first studies to investigate the effectiveness of ACO
principles in shaping patients' attitudes and behaviors. By establishing the role of healthcare
consumerism in shaping patients' attitudes and intentions, this research fills the gap in healthcare
services literature and highlights the effects of ACO principles and healthcare consumerism on patient
care and satisfaction.
Keywords: Consumerism, Accountable Care Organizations, Healthcare, Type II Diabetes,
Pharmaceuticals, Patient-centric decision-making, Patient satisfaction.

Development of an Antioxidant-rich Functional Food Additive from Orange-
processing By-products
Time: 10:15
Author(s): Erik Dassoff, Justin Huynh
Faculty Mentor(s): Olive Li
Abstract: Orange pomace (containing peel, seeds, and pulp) is a by-product of the juice processing
industry, accounting for over half the weight of the whole orange. While, traditionally, orange pomace
has been used as animal feed, it is a source of high-value polyphenols and dietary fiber. Nevertheless,
several of these polyphenols (polymethoxylated flavones, limonoids, and naringin) may contribute to
the bitter taste of orange pomace extracts. The current study focuses on utilizing the protein-binding
capacity of polyphenols to create complexes which mitigate interactions with bitter taste receptors.
Whey protein, micellar casein, and potassium caseinate were blended with the extract during the
ultrasonic extraction of orange pomace in concentrations ranging from 1.7% to 5%, freeze dried, and
ranked, qualitatively, in terms of bitterness and solubility. Furthermore, both the supernatant and the
precipitated protein fraction were tested. The results indicated that, of the proteins tested, the
precipitated fraction of potassium caseinate, at a concentration of 5% was sufficient to reduce
bitterness while maintaining solubility in water. In addition, a calibration curve was developed for the
Folin-Ciolcalteu assay for total phenolic content. The calibration curve is currently being used to develop
procedures to assess the affinity of orange polyphenols for various proteins and individual amino acids.
Future research will utilize this calibration curve to identify proteins that will achieve higher binding
constants and to assess the stability of orange polyphenols and orange polyphenol-protein complexes.
ALLELOPATHIC IMPACTS OF SCHINUS MOLLE (PERUVIAN PEPPER TREE) ON
INVASVIE AND NATIVE PLANT COMMUNITIES OF SOUTHERN CALIFORNIA
Time: 10:30
Author(s): David Banuelas
Faculty Mentor(s): Erin Questad, Edward Bobich
Abstract: Since Schinus molle (California pepper tree) was introduced to Southern California in 1830, it
has escaped ornamental cultivation becoming invasive. Prior to this study, it had not been had
determined if S. molle possess the same potential for allelopathy or a legacy effect in California as does
S. terebinthifolius in Florida. However, S. molle is known to be allelopathic against crops and associated
weeds. In Mexico, leaf litter and soil of S. molle exhibits stronger chemical inhibition than females. The
first objective of this study, therefore, was to find the role of S. molle in restoration, specifically if
chemical inhibition is selective against native or non-native plant species. Secondly, we sought to
uncover any differential allelopathy amongst both sexes of S. molle. Two separate experiments were
conducted to investigate S. molle allelopathy and potential legacy effect. The first applied mulches from
both genders of S. molle to three native and three invasive plant species. The second experiment sowed
the same species in soil collected from both sexes of S. molle. We expected the male mulch (staminate
flower and leaves) and soil would have a greater inhibitory effect on native and non-native plants
species compared to the control. The results of this study found male pepper tree mulch stimulated
shoot growth in four out of six species tested (A. intermedia, B. nigra, B. madritensis, and S. pulchra) and
did not have a strong effect on germination. Nor did this study find strong evidence that S. molle and S.
terebinthifolius share the same impetus for allelopathy or legacy effects. In fact, S. molle may facilitate
native understory plants based on field observations in three locations. Thus, our study highlights the
need of future research to determine the role of both genders in restoration and management.
Fats, Oils and Grease Effluent Recycling for Food Production
Time: 10:45
Author(s): Joaquin Spolita
Faculty Mentor(s): Maryam Shafahi
Abstract: Fats oils and grease pose a serious concern for water municipalities and private businesses.
Fat, oils and grease (FOG) that are not captured before entering the water pipelines can cause odors,
clogs, and excessive maintenance. FOG is difficult to break down due to its low biodegradability.
Wastewater treatment plants are not typically designed to handle FOG wastewater effectively. The
purpose of our research is to breakdown collected fats oils and grease from the food industry, process
them and use them for a hydroponic plant set up to grow vegetables suitable for human consumption.
In order to treat the collected raw FOGthe process will be broken down into filtration, sedimentation,
neutralization, and oxidation. Each step tuned specifically to enhance microbial breakdown of the FOG.
The resulting liquid will be tested for macronutrients, trace minerals, and pH levels, to be used for a
hydroponics system. The results from this experiment will evaluate the possibility of utilizing FOG to
development a low-cost sustainable food production system.
Aquaponics
Time: 11:00
Author(s): Vincent Mota, Dakota Galindo, Du Tran
Faculty Mentor(s): Maryam Shafahi
Abstract: Aquaponic Systems Overview
Aquaponics integrates fish and plant farming to create a closed loop, self-cleaning system. Fish
waste and uneaten fish food is first broken-down bacteria, which turns toxic ammonia into nitrites and
then nitrates. The nutrient rich water is then fed to the roots of plants which further clean the water,
allowing it to safely flow back to the fish. This closed loop provides many advantages over conventional
produce and fish farming. There is no nutrient runoff or need for chemical fertilizers which helps protect
streams and lakes from harmful algae blooms. The plants are grown without soil, so as a result these
systems can be utilized anywhere including indoors and places with very poor soil quality. There is also
no need for pesticides or herbicides. Conventional recirculating aquaculture systems (RAS) for fish
rearing require high cost nutrient filters and a way to safely dispose of very concentrated organic waste.
Because they can be scaled to fit any application, aquaponic systems have the potential to
increase availability to fresh produce and meats for areas that would otherwise be unproductive.
Combating food insecurity and malnutrition is crucial to having a healthy population, and aquaponic
systems are one way to help.
In an effort to conserve water in the aquaponics process, gray water from washing harvested
produce is reclaimed and used as irrigation. Gray water is classified as water that is soiled by its usage in
bathtubs, showers, sinks, and washing machines. Although not sanitary, gray water is also non-toxic and
generally disease-free. With simple filtration, without the use of chemicals to remove suspended solids,
gray water can be recovered and used to water the plants.

Effects of radiation exposure from the Fukushima accident on sexually-selected
red plumage in the Japanese Barn Swallow
Author(s): Alexandra Gresham
Faculty Mentor(s): Andrea Bonisoli-Alquati
Abstract: The Fukushima nuclear disaster that occurred in March of 2011 let off a suite of radioactive
contaminants that had potential effects on a wide range of species living in the area, one of which is the
Barn Swallow (Hirundo rustica gutturalis). The red coloration on the throat plumage in this species,
determined by the abundance of the pigment eumelanin, has been previously identified as a sexually
selected trait, making it an honest indicator of body condition. To test the link between radioactivity and
coloration, digital photos of wild Barn Swallows were collected from sites contaminated by the accident
as well as control sites. The redness of the throat plumage was analyzed using image analysis software.
In a subsample of 20 photos, we selected areas of 400 and 1600 pixels from the red throat patch in each
photo, and tested for differences in variability of red coloration in order to determine the most reliable
sampling technique. All of the red measurements were tested against the amount of radiation exposure
to determine whether radiation reduced the redness of throat plumage, by reducing eumelanin content
in exposed birds. This study may add to the existing evidence that suggests a link between coloration
and individual body condition in response to radiation and other contaminants.
Heritability of Equine Hair Whorls
Author(s): Tirragen Vixie
Faculty Mentor(s): Cord Brundage
Abstract: Hair whorls (trichoglyphs) have long been correlated with trends in animals' behavior,
temperament, response to stimulus, and preferred laterality. Recent studies in these areas have lent
some scientific backing to horseman's legends, but relatively little work has been done on the
inheritance of whorls through generations. I will be observing and documenting hair whorls on most of
the horses at the WK Kellogg Arabian Horse Center, and requesting whorl information from the owners
of contributing stallions. Trends in these data, such as commonalities in whorl direction, size and
placement through a genetic lineage, will provide evidence on the hypothesis that these traits can be
genetically inherited. Eventually, these data might help us identify the genes associated with particular
hair whorl patterns, and thus the associated motor and personality traits.
Thermographic Image Evaluation of Canine Limbs
Author(s): Ryan Chang, Claire Kwon
Faculty Mentor(s): Cord Brundage
Abstract: Thermographic imaging is a diagnostic imaging technique that captures cutaneous thermal
patterns generated by emission of heat from the body. The heat radiation emitted from the tissue of
the animals is translated into thermal images with a thermographic imaging camera.
The goal of this research project is to determine the normal range of thermographic values for the hind
limb region of dogs. Thermographic images were taken in a temperature standardized location with a
FLIR B400 thermographic camera of dogs (n= 40) lined up next to a background (typically a wall) and
kept still for images to be taken of both the right and left lateral sides of their body. The images were
then analyzed using the FLIR Tools application to identify average temperature patterns along the lateral
surface of the limbs. Thermographic imaging in the veterinary field is a new area of interest and has the
potential to be used further in veterinary medicine and treatment.
Influence of Age on the Therapeutic Effects of Photobiomodulation following
Canine Dental Prophylaxis
Author(s): Andrea Watson
Faculty Mentor(s): Cord Brundage
Abstract: Photobiomodulation has been shown to reduce pain and expedite wound healing in animals.
To determine the influence the canine's age has on the therapeutic effect of photobiomodulation after
dental prophylaxis a low energy GaAlInP laser with a continuous 650 nm wavelength and 100 mW power
output was used. Owners had the option to enroll their canine (n = 24) in the study if they were
receiving an anesthetized dental treatment. During the post-operative recovery, each patient received
irradiation (10 J/cm2) as a member of one of three randomly assigned treatment groups. One group (n =
7) received four treatment points of irradiation on the gingiva of the right upper and lower dental
arcade, one group (n = 8) received four treatment points of irradiation on the gingiva of the left upper
and lower dental arcade, and one group (n = 9) received a mock gingiva treatment without irradiation.
Inflammation and erythema along the gingival treatment area of each canine was scored 24 hours after
treatment by a blinded veterinary evaluator in person or via photograph. The data from this study
indicates a trend of higher evaluation scores with increasing age of the canine patient. The data also
illustrates lower evaluation scores for the canine patients who received photobiomodulation therapy
following dental prophylaxis.
Establishing Chicken Egg Incubation Protocol for a New Vaccine Testing Facility
Author(s): Jordan Markson
Faculty Mentor(s): Cord Brundage
Abstract: The Aspergillus species are fungal agents that cause respiratory infections in people and
animals. The poultry industry is especially impacted by aspergillus associated airway diseases. A
candidate vaccine has been developed by Cal Poly Pomona (CPP) Professor Dr. Jill Adler-Moore in
association with Molecular Express Inc. and Western University. In order to further test and optimize
this vaccine, we developed a Biosafety level 2 (BSL-2) poultry facility at CPP. The first stage in testing the
efficacy of the facility is with the successful incubation of Specific Pathogen Free (SPF) chicken eggs. For
this project, we established an initial protocol for that incubation. Forty SPF eggs (day 0) were acquired
from a commercial supplier. The eggs were rested at 23 degrees Celsius prior to incubation. Eggs were
incubated for 21 days in a cabinet incubator with automated temperature, humidity and tilting control.
Incubator conditions were recorded and eggs were turned daily to normalize exposure. Candling to
evaluate egg development occurred after the 1st and before the 3rd week of incubation. This process
allowed us to determine the hatchability rate of our incubator protocol. Data will be used to compare
results from subsequent incubations to optimize conditions for SPF chickens used in this vaccine testing
facility.
Thermographic Evaluation of Canine Torso Thermal Patterns
Author(s): Claire Kwon, Ryan Chang
Faculty Mentor(s): Cord Brundage
Abstract: Infrared thermography (IRT) is a technological procedure that allows for the detection of real-
time changes in surface temperatures. Immediate visualization of animal surface temperatures gives
insight to detect physiological responses as the body regulates its temperature. To determine expected
thermal patterns in normal, healthy canines (Canis lupus familaris), thermal images were acquired with
the use of a FLIR B400 infrared thermal camera. Each canine (n= 40) acclimated to rooms with ambient
temperatures that ranged from 21°C to 25°C for 15 minutes. At the end of the acclimation period,
canines were positioned at no more than 15°C from the camera to exhibit full lateral sides of the body.
Images were taken at a minimum distance of at least 0.4 m. Surface mean temperatures of the region of
interest (ROI), the torso, were then analyzed in the horizontal and vertical direction to determine
horizontal and vertical thermal patterns of the ROI. An "anchor point" was determined at the lowest
point on the curvature of the spine to accommodate for the differences in pixel area ratio attributed by
individual characteristics of the canines. Observations from this study reveal an increase in average
surface temperatures horizontally across the torso while more variation is exhibited in surface
temperatures present in the vertical direction in canines.
NEUTRAL RED AND CRESYL VIOLET COUNTERSTAINS IN NITRIGERGIC NADPH-
DIAPHORASE STAINED NEURAL AND EPITHELIAL TISSUES
Author(s): Zuhayr Khan, Aayushi Mardia, Jordan Wong
Faculty Mentor(s): Glenn Kageyama
Abstract: Nicotinamide adenine dinucleotide phosphate diaphorase (NADPH-d) histochemistry is used to
study nitric oxide (NO) synthesizing nitrigergic cells. When staining neurons, the NADPH-d histochemical
technique beautifully stains them entirely, including the dendrites, soma and extensive axon
arborizations. Due to not all cells being stained by this technique, it is not possible to know exactly
where these neurons and axon arbors or other nitrigergic cells are located relative to other structures. It
would be desirable to find a counterstain that provides a clear visualization between the stained
nitrigergic cells and the other cell types located in the same area. The NADPH-d histochemical technique
involves the formation of a dark blue formazan reaction product from nitro-blue tetrazolium (NBT).
Unfortunately, formazan tends to be lost during standard procedures for Nissl counterstaining. By
minimizing the exposure of the formazan reaction product to lower grades of ethanol, we have
developed two Nissl counterstaining protocols that are suitable to use with the NADPH-d reaction. The
first protocol allows the visualization of dark blue NADPH-d stained cells in relation to lighter blue Cresyl
Violet (Nissl) stained cells. The second protocol shows more contrast between dark blue stained NADPH-
d cells and Neutral Red stained cells. The new staining protocols will enable one to quantitate the
percent of NADPH-d stained cells in a given area, and determine how they relate to different neuronal
nuclei, tissue layers and blood vessels.
THERE'S MORE TO YOUR GUT THAN INSTINCTS---INVESTIGATING THE
BACTERIAL PROTEIN BAIH
Author(s): Laurin Randle, Amanda L. Cao
Faculty Mentor(s): Kathryn McCulloch
Abstract: In humans, bile acids are recycled from the liver to the intestines and then back to liver in a
process known as enterohepatic circulation. This process allows for nutrients to be reabsorbed and
helps regulate metabolism and homeostasis. However, some bile acids are passed on to the intestines
and specific bacteria within the gut produce harmful products from these bile acids. These harmful
products are formed in the process of 7α-dehydroxylation and result in toxic acids that can lead to a
variety of disease and even cancer. Thus, the 7α-dehydroxylation pathway is a large topic for study due
to its link to discovering more on factors affecting human health regarding the gut. This study focuses on
a gene, baiH, within the bile acid inducible operon that encodes enzymes within the 7α-dehydroxylation
pathway. The nature of this study involves the recombinant over expression and purification of BaiH
from E.coli. Previous research has characterized BaiH as alike to flavoproteins which reduce α/β-
unsaturated carbonyl compounds. The gene has been known to perform oxidative reduction chemistry
on stereo-specific NAD(H)-dependent 7β-hydroxy-3-oxo-Δ4-cholenoic acids. This study is a continuation
of a previous experiment involving the characterization of the gene baiH. The methods of purification
include ion exchange and size exclusion and each method is analyzed for its efficiency. The purification
will allow the isolation of the target protein, determination of the activity of the protein present using
an assay, possibly crystallization and overall comparison to previous work done that utilized other
purification methods.
Staphylococcus epidermidis Biofilm Formation on Traditional and Boron Metal
Alloys
Author(s): Jeyashree Alagarsamy, Cindy Toscano, Kevin Robles
Faculty Mentor(s): Steve Alas
Abstract: Higher biocompatibility and corrosion resistant biomaterials are more frequently being test-
implanted for a wide range of purposes. However, surgery-related infection and implant microbe-
colonization is generally the most common complication. When bacteria adhere to and proliferate on
the biomaterial surface, the bacteria produce extracellular polymeric substances, primarily
polysaccharides, which mediate cell-to-cell adhesion and form a biofilm. Our long-term goal is to extend
the life of a prosthetic implant by identifying new metal alloys that are less susceptible to bacterial
colonization. Using one of the major biofilm producing bacteria commonly found to colonize surgical
implants, Staphylococcus epidermidis, we investigated the biocompatibility of novel metal alloys with
regard to their susceptibility to biofilm propagation. The Experimental biometal alloys examined were
stainless steel (SS), commercially pure titanium (CPTi), titanium alloy (Ti64), dental grade titanium (Ty)
and titanium-boron metal alloys. Biofilm formation was analyzed using crystal violet staining and
fluorescent microscopy. Ideal experimental conditions were obtained using flasks or a biofilm reactor.
Biofilm reactor experiments were performed with (continuous culture) or without a constant infusion of
growth media (batch culture) during biofilm formation. Results indicate that the Ty alloy permits less
biofilm formation than traditional metals. Titanium-boron metal alloys, Ti64+0.04% B and Ti64+0.1% B,
showed the least amount of biofilm compared to other metal alloys. Thus, we show that, compared to
traditional metals such as stainless steel and pure titanium, the Ty, Ti64+0.04% B and Ti64+0.1% B alloys
may be better alternatives as a modern prosthetic biometals.
Ibuprofen Transdermal Delivery via Microemulsion
Author(s): Alan Sierra
Faculty Mentor(s): Laila Jallo
Abstract: Oral administration of Ibuprofen presents many challenges. Ibuprofen can cause upset
stomach, as a hydrophobic drug it demonstrates poor gastrointestinal absorption due to its low water
solubility , and as a result of the first pass response is reduced in concentration by the liver. Topical
administration of Ibuprofen as oil-in-water microemulsion increases the bioavailability of the drug and
as a result of bypassing the liver all together, increases its safety. In this study, different ratios of
Medium-chain triglyceride oil and corn oil were used as solvents to increase the skin permeability of the
drug along with Tween 80 surfactant to decrease the surface tension of the microemulsion and keep it
in solution. All ratios set in 25% change of oil intervals were stable and the emulsion of 75% MCT, 25%
corn oil, and .15g in 8mL DI water produced the smallest droplet sizes at .119 µm.

Understanding Disinfection By-Products and Methodologies to Reduce
Disinfection By-Products in Water Treatment
Author(s): Laura Lopez, Vian Duong
Faculty Mentor(s): Ali Sharbat
Abstract: The preliminary study of water disinfection began in the mid and late 1800s due to the
numerous health hazards due to chemical and microbial water contamination. Although there are many
existing methods of water treatment, disinfection by-products (DBPs) have remained as one of many
challenges and limitations to safe drinking water. DBPs have been one of the major concerns at the
Laguna Vista Elementary School in Oxnard, California. Water samples from the school's water supply
revealed an increase in total trihalomethanes (TTHMs), a DBP, which exceeded the regulated maximum
contaminant level in 2015, posing health risks to the public. DBP formation results in the chemical
reaction between chemical disinfectant agents with the natural organic matter in water. Due to ideal
conditions in the formation of THMs, variations of water treatment procedures, such as chemical
coagulation, ion exchange, and nanofiltration, in the removal of natural organic matter and bromide will
result in decreased DBP formation. Other methodologies to reduce DBPs formation include ozone,
adjusting water pH levels, chloramines, and ultraviolet irradiation. Results from these procedures are
expected to be lower DBP concentration; however, considering methodology limitations, its
effectiveness will vary on the apparatus of the water system, contaminants within the water, and
disinfectant. Further research regarding DBP and will classify the proper techniques and technology to
reduce TTHM formations.

Faculty Mentor(s): Vilupanur Ravi, John Hooman
Abstract: Human comfort in regards to clothing systems depends upon the ability of the fabrics and
their construction to transmit perspiration away from the body. If the clothing system is inefficient in
this regard, the wearer will experience a great deal of discomfort and physiological distress. It is critical,
therefore, for the clothing to be "breathable" This project was an attempt to quantify the effect of
environmental factors on the creation and transport of moisture/moisture vapor through different
fabrics. The physics of the phenomenon will be described. The design and construction of a custom-
made apparatus will be reported. The apparatus utilizes a controlled water heater, a
humidity/temperature sensor, a fan, and a weighing scale. The results will be reported and discussed.

Photosensitizers are used in Photodynamic therapy (PDT) to treat various medical ailments including
cancer, acne vulgaris, skin and organ diseases, bacterial infections, and sexually transmitted diseases.
When photons of necessary and specific wavelengths interact with photosensitizers, reactive oxygen
species (ROS) are generated which damage the cellular structure of the infected tissue - inducing cellular
necrosis and lysis or apoptosis. Ideal photosensitizers have a high quantum yield of singlet and triplet
oxygen which damages the infected cells. Computer-aided molecular design (CAMD) was employed in
order to search for new photosensitizers with such desirable traits. Quantitative structure-property
relationships (QSPR's) were defined based on 21 different known photosensitizer structures for
properties, singlet oxygen quantum yield and molar extinction coefficient. Connectivity indices were
used as molecular descriptors to develop QSPRs. Correlations were obtained by linear regression.
Chemical moieties were then analyzed, processed, and recombined using combinatorial optimization
techniques in order to develop new photosensitizers. The optimization formulation minimizes the
difference between the properties of the newly built photosensitizer and the target value and it is
solved stochastically using the Tabu Search algorithm. Novel candidate photosensitizers have been
proposed here for future research and use in PDT.
Computer Aided Molecular Design Of Esterase Resistance Hydrophilic Dental
Adhesive Monomer
Author(s): Yonas Rufael, Ruben Molina
Faculty Mentor(s): Farhana Abedin
Abstract: It has been shown in the past that salivary esterase enzyme breaks down the methacrylate
bond of the dental adhesive monomers. Moreover, other studies have shown that dental adhesive
undergoes phase separation into hydrophilic rich phase and hydrophobic rich phase during infiltration
through the demineralized dentin. The hydrophilic rich phase has limited quantity of cross-linker, which
plays a crucial role in higher dentin/adhesive bond strength and preventing water penetration. Thus,
higher cross-linker concentration in the hydrophilic-rich phase will impart extended clinical lifetime to
this phase. Moreover, low crosslinking density can cause bacterial penetration leading to recurrent
decay and hence failure of the composite restoration. So, the purpose of this research is to design novel
dental cross-linker monomers that are resistant to salivary esterase enzyme and are also hydrophilic rich
in nature. This will be achieved by Computer Aided Molecular Design (CAMD). Quantitative structure
property relationships (QSPRs) were developed for properties, octanol/water partition coefficient and
cholesterol esterase inhibition constant using descriptors, connectivity indices. An optimization
formulation that minimizes the difference between properties of newly designed molecules and target
values was solved via stochastic algorithm, Tabu search.

Design and Modeling of a Nozzle for Compressable Air Flow with Entrained
Molten Aluminum Particles
Author(s): Raymond Faull
Faculty Mentor(s): Kevin Anderson, Nicole Wagner
Abstract: The purpose of the project is to determine whether it is possible to design a nozzle that takes
compressed air at 60 psi with entrained molten aluminum particles and outlets the flow to atmospheric
air at subsonic velocity with an organized distribution of the aluminum particles for industrial
engineering applications. In order to accomplish this, analytical compressible flow analysis was
performed alongside modeling of the flow in Ansys Fluent computational fluid dynamics software. The
computational fluid dynamics analysis was performed using various 2 dimensional model geometries
with only the steady state air flow. If it appeared that the air flow would work for the application then a
transient model analysis of the flow was performed with the molten aluminum particles being injected
using the Discrete Phase Modeling in Fluent. The results of these designs, analyses, and models, as well
as, whether the design criteria can be accomplished will be presented.
Iron Oxide Nanoparticle-Containing Composite Nanofibers Made by Co-
electrospinning and Hydrothermal Carbonization
Author(s): Shivani Patel
Faculty Mentor(s): Yong Gan
Abstract: Co-electrospinning of polyacrylonitrile (PAN) and synthetic black iron oxide (Fe3O4)
nanoparticles was performed to prepare polymer composite nanofibers. The polymer composite
nanofibers were heat treated at 250oC in the air to oxidize the PAN first. The fibers were then further
heat treated at 500oC in argon gas to cause the PAN to be partially converted into carbon. The heat
treated fibers contain carbon as the matrix and iron oxide (Fe3O4) nanoparticles as the fillers.
Photosensitive tests showed that the composite nanofibers possess the photovoltaic property in visible
light. In UV light, the composite fibers are not photosensitive. To coat the composite fibers with active
carbon, some of the nanofiber samples were placed in a 10% dilution of sugar water in a non-stirred
high pressure reactor to allow for hydrothermal carbonization. Several tests were applied to these
coated samples. A light emission test was applied by using an electrochemical analyzer and a color-ink
absorption test was applied by using a spectrometer.
Nickel Oxide, Cobalt Oxide and Titanium Oxide Loaded Composite Carbon Nano
fibers Prepared by Co-electrospinning and Hydrothermal Carbonization
Author(s): Saurabh Kansara
Faculty Mentor(s): Yong Gan
Abstract: The present paper examines the properties of nickel, cobalt, and titanium oxide containing
carbon based composite nanofibers. These nanofibers were made using DMF as the solvent, PAN as the
precursor and their respective metal salts as the metal oxide sources. The solutions were drawn into
nanofibers through a co-electrospinning process followed by heat treatment. These nanofibers were
thermally oxidized at elevated temperature of 250oC to stabilize the structure of PAN. Then, even higher
temperature heat treatment at 500oC in a furnace with argon gas protection was performed to
carbonize the material. After that, the nickel oxide and titanium oxide-containing nanofibers were
coated with active carbon in a diluted sugar solution via hydrothermal carbonization. The obtained
products were tested in view of light sensitivity and color-ink absorption using an Electrochemical
Analyzer and a Vis-UV Spectrometer, respectively.
Constitutive Model of PLG 10-90 for Anterior Cruciate Ligament Reconstruction,
Author(s): Peter Kuetzing
Faculty Mentor(s): Mehrdad Haghi
Abstract: There are an estimated 100,000 cases of torn Anterior Cruciate Ligaments (ACL) in the United
States each year. Although autografts and allografts are approved treatments, they are expensive, labor
intensive, cause donor site morbidity, and require a lengthy patient recovery process. Despite
decellularization treatments, DNA left in allografts can increase the risk of disease transmission and
immunogenic response. Synthetic implants eliminate the harvesting procedure and have great
biocompatibility. Understanding the time dependent properties of a synthetic material that closely
matches those of native ligaments is imperative for ACL reconstruction innovation. PLG 10-90 (L-lactide -
co-glycolide) monofilament is an absorbable biopolymer and strong candidate for ACL reconstruction.
The biopolymer sufficiently matches average native ACL tensile strength and percent elongation to
fracture. Additionally, the dissolution time of PLG 10-90 is approximately the same as ACL growth time.
This inversely proportional relationship offers the potential of scaffold reconstruction procedures. This
research will determine a set of evolutionary equations which predicts failure under a variety of
conditions. Specimens are stored under an assortment of loads at in-vivo conditions. A specimen is then
subjected to one of several tensile tests, including a jump test, to determine the properties at different
time points. These tests illustrate the time dependent properties in terms of rate of dissolution and
strain rate. This data will show a relationship between the strength of PLG 10-90 and its dissolution
which is required to build a constitutive model and determine the viability for ACL reconstruction.
Optimization of Hyperbolic Metamaterials Using Gold, Silver, Copper, and
Aluminum
Author(s): Bo Shrewsbury, Librado Mancilla, Gobind Sohi
Faculty Mentor(s): Ertan Salik, Ildar Salakhutdinov
Abstract: Hyperbolic Metamaterials (HMMs) allow for the propagation of Surface Plasmon Polaritons
(SPPs) and Long-Range Surface Plasmon Polaritons (LRSPPs), which interact to form what we call Bulk
Plasmon Polaritons (BPPs). These HMM structures are promising in the field of refractive index sensing
due to the unnaturally high effective refractive index of some modes propagating within the structures.
Our goal is to achieve an effective refractive index of 8.1, which is approximately double the highest
refractive index found in nature. These HMMs are made from nanolayers of alternating conducting and
dielectric materials. We used silicon dioxide for our dielectric material in each of the following cases.
Gold, silver, and copper achieved an effective refractive index of 8.1 or slightly greater with 26 7.5nm-
thick layers and aluminum achieved this goal with 26 5.5nm-thick layers.

Electrochemical characterization of a titanium alloy - effect of pH
Author(s): Diana Costescu
Faculty Mentor(s): Vilupanur Ravi
Abstract: Titanium and titanium alloys are widely used as implants in the human body. This is because of
their advantageous mechanical properties, corrosion resistance and biocompatibility. The alloy that is
most commonly used is Ti-6Al-4V which is a titanium-based material containing 6 mass % of aluminum
and 4 mass % of vanadium with the rest (90 mass %) comprised of titanium. Although this alloy has been
in use for a while, it is important to understand their stability in the body because of the increasingly
longer life expectancies of the population as a whole. A problem of importance is the discharge of metal
particles into the tissue encompassing the implant, which can cause adverse reactions in the body. It is
well known that the pH in the vicinity of an implant can vary quite dramatically during and immediately
after surgery. These shifts in pH can cause a local increase in the rate of corrosion. The goal of this study
was to investigate the impact of three different pH levels on the corrosion behavior of Ti-6Al-4V in a
phosphate buffered saline solution utilizing electrochemical methods. The results will be reported and
discussed.
Characterization of Oxidized Metals
Author(s): Samantha Villanueva, Isabella Chu, Samuel Navarette
Faculty Mentor(s): Vilupanur Ravi
Abstract: Metallic materials such as stainless steel can become brittle and weak when corroded. The
rate of corrosion increases at high temperatures, and in turn, the effect of corroding or oxidizing the
metal can lead to a rapid loss of engineering function and result in equipment failure in industrial
conditions. Stainless steel is of particular interest because it is used in many applications and fields.
Stainless steel also passivates, meaning that it produces a protective oxide layer that helps prevent
further corrosion. Understanding the nature of these oxide films will be helpful in developing ways to
improve corrosion protection. This project had the objective of characterizing thin oxide films through
optical/visual methods and microscopy. The results will be reported and discussed.
Deposition of thin salt films on metallic substrates
Author(s): William Omenwu, Dominic D. Dinh, Steven T. Pierce
Faculty Mentor(s): Vilupanur Ravi
Abstract: The corrosion underneath thin molten salt films is a major problem in some industries. A
notable example is the "hot corrosion" of turbine blades in aircraft flying over marine atmospheres or
land-based turbines located near the sea. Simulating this type of corrosion in the laboratory is
important. Proper experiments can help in evaluating the mechanism of this phenomenon and guide the
selection of appropriate materials for these environments. The first step in this research is to develop a
technique to apply precise amounts of salt to the surface of metals. In this summer research project, a
method called "salt-dripping" was investigated in order to obtain specific amounts of chosen salts onto
selected metallic substrate with the goal of finding the most effective method of coating stainless steel
304 and 316 with a thin layer of a salt combination, i.e., sodium chloride (NaCl) and sodium sulfate
(Na2SO4). The tests conducted were done to find an optimum method that could be used to form a thin
uniform layer of salt, these methods include spraying the salt solution on the surface of my metallic alloy
using a spray bottle or using a pipet to dispense the salt water on the coupon and using a cotton swab to
distribute the salt water on the surface of the coupon. The results will be reported and discussed.
A Comparison of Advanced Oxidation Effectiveness with Hydrogen Peroxide and
UV in Solar and Synthetic Systems
Author(s): Alejandro Cerano-Lopez, Paola Nieto-ArredondoEllen Chan
Faculty Mentor(s): Monica Palomo
Abstract: Adverse health and ecosystem concerns have increased from remnant trace organics in
municipal wastewater effluent1. Long-term exposure to trace organics can cause cancer, reproductive
system damage, and major organ diseases2. Additional treatments such as advanced oxidation
processes (AOPs) are used to degrade this trace organic pollutants, however current treatments are not
cost and time efficient. Advanced oxidation processes like H2O2/ UV irradiance are investigated on their
efficiency to decompose trace organics of wastewater samples. Two non-toxic trace organic substances
dissolved in water were treated with high ultraviolet light in order to evaluate the decomposition of the
contaminants. Two sets of experiments were conducted with hydrogen peroxide to oxidize the organic
contaminants. One treatment involved using a lab-scale solar UV simulator with a 120 watt lamp at 254
nm. The second treatment exposed solution mixtures to UV sunlight. A spectrophotometer with UV-
visible range detection was used to determine concentration of contaminants.This study's objective is to
verify that AOP via H2O2/UV is a preferred method to remove trace organics. Implementing this
method will lead to more resource efficient treatments resulting in higher water quality subsequently
improving ecosystem health.
Identification of Flight Dynamics Models of a Multicopter using Flight Data
Author(s): Vanessa Gonzalez, Thomas Elemy, Edwyn Ramirez
Faculty Mentor(s): Subodh Bhandari
Abstract: This presentation talks about flight-testing, data collection, data processing, and system
identification of a multicopter unmanned aerial vehicle (UAV). The multicopter was flown extensively for
the identification of flight dynamic models and verification. The collected data was first processed using
MATLAB, and then converted into a frequency response using CIFER (Comprehensive Identification from
FrEquency Response) software. The frequency response was then used for the identification of transfer
function and state-space mathematical models of the Y6 multicopter in hovering flight. Different tools
within the software were used to analyze the data and for the model identification. Methods of flight
data collection, data types required for the identification and verification, identified models, and
comparison between the identified model response, and flight data will be presented. Future work will
involve automating the frequency sweeps using computer-generated code for optimal flight-testing and
model identification. Identified models will then be used for the design of flight controllers using
advanced control system design techniques.

Faculty Mentor(s): Subodh Bhandari
Abstract: This presentation talks about a system for autonomous navigation and target recognition for
indoor search and rescue missions using small unmanned aerial vehicles (UAVs). The use of lightweight
multicopters makes them ideal for maneuvering through tight spaces and locating victims in shorter
time. Simultaneous Localization and Mapping (SLAM) techniques and Collision Avoidance Systems (CAS)
are used to navigate the vehicle in the GPS-denied environments. SLAM, CAS, and target recognition
software can help rescuers locate victims for disaster relief. Using a LIDAR and camera, it is possible to
create a map of an indoor environment and determining and keeping track of the UAV's in the
constructed map. The victims can be identified using onboard image processing. An RPLidar is used in
conjunction with HectorSLAM algorithm localization and mapping. A Mobius Actioncam is used for the
victim identification. The identification software runs on an NVidia Jetson TX1 microcomputer. The
Jetson TX1 communicates with the onboard Pixhawk flight controller, while also transmitting data to a
ground station using Xbee radio modules. Neural networks are used for the identification of victims as
well as for collision avoidance with the wall so that the UAVs navigate the indoor environment safely.
Simulation and test results will be presented. Work is underway to test the overall system in flight for
realistic search and rescue missions in the indoor environment.

Author(s): Margaux Retherford, Mitchell Caudle, Grace Lewis
Faculty Mentor(s): Subodh Bhandari
Abstract: The integration of unmanned aerial vehicles (UAVs) into the national airspace system presents
itself with a myriad of technical problems. One of the key requirements for this integration is the human
equivalent level of safety, which requires the ability to detect and avoid other aircraft/obstacles in their
flight path so that the UAVs complete their mission without any loss or damage to other aircraft or
property. This presentation talks about the use of ADS-B (Automatic Dependent Surveillance- Broadcast)
transponders for detection of collision of other similarly equipped aircraft/UAVs. ADS-B transponders
can receive and broadcast global position and velocities among other pertinent information in a 100-
nautical mile radius. This research used Ping-2020 ADS-B transponders for the collision detection. The
collision detection and avoidance is first tested in software-in-the-loop simulation, which also uses the
flight controller, Ardupilot, and ADS-B transponders in the loop. MAVproxoy, a UAV ground station
software package, is used to communicate between in the autopilot and simulation environment via
MAVLink. FlightGear flight simulator is used to visualize the motion of the UAVs.
The research uses two fixed-wing aircraft equipped with Pixhawk autopilots, which allow autonomous
waypoint navigation. The collision avoidance algorithms use a three-step system of detect, predict, and
avoid. The algorithm calculates and sends the waypoints for collision avoidance to the autopilot. Using
the kinematic equations, the UAV velocities can be calculated from the information received from GPS
sensors, and future positions can be predicted. The collision avoidance algorithm is tested using the
incoming information from real-time aircraft.
GPU Accelerated Encryption of Big Data Using ElGamal
Author(s): Leni Halaapiapi

Abstract: In this day and age, information is power. With a lot of our data stored digitally and online, it
could be susceptible to malicious cyber attacks. The only way to defend against these attacks is to use
better encryption methods. Standard encryption practices, such as the AES encryption algorithm, can
use anywhere from 128-bit to 256-bit encryption, which is relatively safe, but as technology improves
over time, so to do hacking methods. One way to have more secure encryption is to increase the size,
but there are trade-offs. The larger the size of an encryption scheme, the more time it takes. This is
where GPU accelerated encryption comes in.
Statistical Computation on Encrypted Genomic Data
Author(s): Anna Poon
Faculty Mentor(s): Tingting Chen
Abstract: Since the Human Genome Project, research on genomic data has been on the rise and
genomic data is become more readily available. Genomic data contains essential information regarding
diseases, sub populations, and individuals, allowing us to pursue ambitious medical research, like
personalized medicine. Genomic data is, however, different than other data we collect. It is permanent
and unique to each individual. Any risk of privacy can not only expose the individual but the privacy of
their relatives as well. Thus, it is significant to protect the privacy of the genomic data in the cloud, as we
use the data for the advancement of medicine. Our research allows for us to compute statistical
formulas like the Fisher's Exact Test on encrypted genomic data, using homomorphic encryption. We
utilized a Boneh-Goh-Nissim cryptosystem with GPU Acceleration for faster encryption and
computation. The goal is to encrypt data securely before storing the data into the cloud and allow for
meaningful computations on encrypted genomic data.
Finding Harmony in Security: An Exploration of EEG and Music for
Authentication
Author(s): Joseph Cauthen
Faculty Mentor(s): Mohammad Husain
Abstract: Electroencephalography (EEG) has been researched as a potential biometric for almost two
decades. The most promising techniques to obtain reliable authentication credentials have been the
use of evoked potentials, or the process of measuring the change in neurological activity induced by
introducing the subject to a stimulus. Research in which the stimuli are visual have yielded accuracy
rates approaching those of other popular biometrics. However, if EEG authentication was to become a
viable biometric, visual stimuli has practical drawbacks. Using evoked potentials, this study investigates
the efficacy of auditory stimuli, more specifically music, instead. Using statistical analysis on the time-
frequency readings of 5 participants this study seeks features of musically evoked potentials that have
the necessary properties for authentication.
Please Blink Your Password: Converting Morse Code Eye Activity to Text using
EEG
Author(s): Angela Gadon
Faculty Mentor(s): Mohammad Husain
Abstract: In Electroencephalograph (EEG) readings, eye blinks are considered an obstacle to brain-
oriented analysis. Blinking causes a distinct disturbance in the time series, allowing one to track when
eyes open and close. Many programs aim to filter out these blinks from EEG data by recognizing and
erasing them. The potential of blink readings, however, can be utilized instead of eliminated: these
readings can be used as a safer version of LED eye-blink reading. In this research, EEG is used to convert
eye blinks in Morse code into text for possible application in alternative computer interfaces and as a
factor of authentication.
Eye Tracking Data Analysis and Application
Author(s): Jessie Uyan, Irvin Cruz
Faculty Mentor(s): Sampath Jayarathna
Abstract: By using biometrics the eye movement that can be analyzed to determine if a subject has
difficulty learning. The recording of eye movement is done by using an eye tracking machine. The eye
tracker we are using is the GazePoint GP3 for this research. Subject's eye movements are being recorded
as stimuli that simulates a learning experiences are shown to them. The machine then records raw data
from the participant such as the timestamps and coordinates of where that subject was looking during
the simulation. We process this data through an algorithm, the 2-D Oculomotor Plant Mathematical
Model (2DOPMM), in order to separate the raw data into the main eye movement types such as
fixations, gaze following, or saccades. Our focus being in fixations and saccades. From this a subset of
data, a feature-set can be extracted measuring characteristics such as amount of fixations, duration, and
length of both types eye movements. In order to obtain results, a large amount of feature sets will be
collected in order to create a baseline of what eye characteristics define a problem with learning. With
integration into concepts such as machine learning we may apply these feature-sets to determine if a
person may have difficulties in a learning environment. From this we can then bring focus and attention
to those with learning disabilities to better improve their educational quality.

Abstract: machine learning is an idea that feeding data to the machine model and it builds it own logic
based on the data, and thus is able to generate results that approximate the aimed result. In this visual
preference research, the goal is to train a machine model that can recognize people's faces. The model
is named ResNet50, which is a Deep Convolutional Network model that is used to perform image
classification task. The dataset includes 5500 people's face images that have a score of 1 through 5 of
how attractive they are. Through using python, the dataset is preprocessed and the machine model is
feed with those images. After 30 epoch of training and 200 times of validation set, the ResNet50 is able
to score human face that closely approximates the scores of images were tagged.
Tensroflow object detection
Author(s): Ping-Yang Gao, Mustapha Farraj
Faculty Mentor(s): Hao Ji
Abstract: Object detection is the process of locating and classifying objects, which can do such as video
surveillance, robot navigation, etc. Deep learning based object detectors are trained from images with
known classes of objects; these detectors can only detect a set of object classes that are known at
training time. If we want to detect a new object class, we need to re-train our custom detector.
However, this training process requires a large amount of images of the custom objects with annotated
bounding boxes and performed manually by humans, which is costly and tedious. This causes substantial
barriers to build custom detectors for arbitrary objects.
To tackle this problem,our project targets a fully automatic framework of building an object detector for
custom objects. In particular, we will leverage 3D model reconstruction to automate the generation of a
large amount of annotated image data for target objects. Instead of annotating images and creating the
bounding boxes, we only need to name the 3D object's masks once and render 3D objects to generate
2D images and its masks with different backgrounds and situations. Then, masks give the names of
objects and their size and location to annotate images, which then help fine-tune deep learning models
to yield an object detector with compelling identification accuracy of the custom objects. We evaluate
this automatic framework, showing that it achieves satisfactory accuracy with limited user assistance
while running in real-time on webcam and mobile devices.
Object Detection

Abstract: Object detection is an easy process for a user to detect an object in images or videos. Object
detection is being used every day either by video surveillance, robot navigation or poses estimation.
Using machine learning we are advancing a lot in technology to have accurate object detections. The
way that deep learning base object is trained is by using a set of images with classes of an object. It is
important to know that the object detection will only detect the exact objects classes that were trained
to. If needed to detect a new object a new training set is needed for that object. the training process
takes a big number of pictures of the same object and an annotated bounding box. The problem
nowadays is the bounding box is manually performed by a human which is costly takes a lot of time. The
objective of this research is to make this project target a fully automictic framework to build and train all
the object needed. In order for that to happen a 3D model will automatically generate a lot of images of
the target. Which these images will help the processed objects to be detected easily. This software will
achieve satisfactory accuracy with limited user assistance while running in real-time on webcam and
mobile device.
Toward Better Image Classification
Author(s): Eitan Rothberg
Faculty Mentor(s): Hao Ji, Tingting Chen
Abstract: As proficient as image classifiers have become, they still fail to recognize images in the way
that we might hope. They can detect airplanes accurately, but the sky plays an important role in that
detection. They can detect cars, but are likely to use the road as an indication. We confirm this
experimentally through the use of the first localized, imperceptible adversarial attack -- by changing
pixels in the background of an image, we are able to fool image classifiers.
We further contribute to adversarial research with our new adversarial training technique. By training
classifiers on both normal images and images with adversarial backgrounds, we seek to maintain the
state-of-the-art benchmarks for classification accuracy while creating more robust models that focus on
the object itself.
Intrusion on Blockchain Infrastructure via Multichain Platform
Author(s): Yegor Shea
Faculty Mentor(s): Ronald Pike
Abstract: Massive amounts of data are being stored on blockchain infrastructures. The best known asset
that uses blockchain is Bitcoin, a cryptocurrency that is being used across the world. Since the Invention
of Bitcoin in 2009, cryptocurrency has become a well known currency that is being used today, but is it
as secure as everyone believes it to be? Blockchain, a shared ledger technology, is the platform on which
bitcoin runs its transaction. It is believed to be very secure as each block in the chain is specified with a
specific hash. These hashes are used to verify the validity of the chain, each block will look at its previous
blocks hash before continuing. In essence if one block has been compromised the rest of the chain will
know and will not operate. In my research I propose developing multiple attacks that will compromise a
blockchain such as a Dos Attack, DDos attack and a Re-Entry attack.
Exploring SDN and SIEM Integration
Author(s): Carlos Marquez
Faculty Mentor(s): Ron Pike
Abstract: A SIEM (Security Information and Event Management) is a tool used to aggregate, normalize,
correlate, and present event log data and network flow traffic from endpoint machines, servers running
critical business services, antivirus appliances, network infrastructure components, and more. Software-
Defined Networking (SDN) allows the separation of the control plane and the data plane in network
devices, giving control of network flow routing to a centralized controller. While a SIEM provides a high
level of visibility, it can take more time than is optimal for the user to take appropriate action based on
their findings. This project uses enterprise-class switches, IBM QRadar SIEM, and OpenDaylight Nitrogen
to see how integration between SDN and SIEM could be used to improve network metrics being
measured by the SIEM and allow for user-configured automated network-level responses to detected
anomalies in the event logs or network flows. The implementation of such responses could, for example,
reduce the need to spend crucial time relaying quarantine orders between appropriate teams for hosts
that are known to be infected with malware. This could result in cutting off the spread of the malware
upon detection. If automation is not an option, then this same integration could be used to allow one-
click options for the same actions in the SIEM interface. The end result is the same - reduced response
time to potentially critical threats.
DDOS Attacks Against the SDN Control Layer
Author(s): Dennis Tran
Faculty Mentor(s): Ronald Pike, Mohammad Husain
Abstract: Software-defined networking is a relatively new phenomenon that allows networks to be
more robust, flexible, and cost-effective. By separating the control plane and the data plane, SDN allows
a logically centralized controller to manage an entire networking environment. As an increasing number
of firms work to integrate SDN, the need for SDN security increases as well. The distributed denial of
service attack (DDOS) is a common and effective form of attack that aims to consume the resources of a
certain system in order to prevent legitimate users from accessing it. While DDOS attacks normally
target individual servers, the constant need for communication between the control plane and the data
plane creates a bottleneck that attackers can leverage in a DDOS attack. Previous works have studied
the control plane saturation attack using primarily TCP floods that could then be countered with a proxy
that only forwards packets to the controller after a TCP handshake is completed. In this project we
investigate alternative protocols such as UDP and ICMP that may be used in the same attack, and we
test the effectiveness of some common IPS systems against the attack.
Real vs. Simulated: Analyzing Implementation Algorithms for ROS
Author(s): Matthew Ortega
Faculty Mentor(s): Fang Tang
Abstract: GPS navigation is utilized in a wide scope of applications from providing vital information for
rescue efforts to the navigation of robots built upon a robot operating system (ROS). The critical aspect
of this research is to perform efficient point to point navigation with real-time GPS data. The capabilities
of a robot using ROS is limited in that an extended kalman filter is used to provide state-estimation
information for the internal GPS navigation to perform efficient path planning. GPS signal can be subject
to interference from external sources regardless of where the data is being sent to and thereforeraises
possible expectations of error (i.e. noise) in the form of accuracy and precision. It is then imperative to
implement an algorithm that would produce newly filtered GPS data that is processed to perform point
to point navigation in a robot. The filtered GPS data will then be mapped for comparison between a
simulated environment and the University Quad at Cal Poly Pomona. Since the use of a simulated
environment can cause little variation in expected results, this data set is expected to be close to the
desired outcome of the implementation and filtering algorithm. By analyzing the simulated vs real data
sets, the research intends to produce a more efficient method of implementing GPS data for ROS
systems.
