To Our Seniors and Design Exposition Day Attendees:

On behalf of our School of Engineering & Applied Science, I

would like to welcome all of you to the culmination of a year of very

committed work by our seniors, their faculty, the project partners, and

numerous others involved with these student projects. For many of our

seniors, the completion of a Senior Design project is among the most

memorable of their many Gonzaga experiences. The detailed

planning, challenge, struggle, and accomplishment associated with

these projects provide experiences that will be carried forward into

the professional and life experiences of our graduates. What started as a simple proposal in

September has evolved through the hard work of the seniors into the final design presentations

that we see today.

To our seniors: As your Dean, I take great pride in your accomplishments, creativity, and

innovation – you truly inspire us! I am delighted to report that you have more than lived up to

expectations through fascinating, challenging projects carried from concept to completion this

year. I want to congratulate all of you for the effort and dedication that has brought you to this

day, an effort that began not just last September, but when you first entered Gonzaga as a

student. Please know that the faculty and staff of our School are proud of you and your

achievements. We welcome you to a profession in which you can find lifelong excitement,

continuing opportunities to challenge and improve your skills, and many occasions to follow the

Jesuit tradition as you seek to serve both humanity and nature as reflections of God’s

creation. Go Zags!

Center for Engineering Design

& Entrepreneurship was

established in 1992 to enhance

the design experience for

senior engineering students.

The Center organizes projects

for the academic year that are

commissioned by sponsors in

the private and public sectors.

Prospective sponsors are

sought throughout the year for

p r o j e c t s i n v o l v i n g a l l

engineering and computer

science programs. Some projects are interdisciplinary.

Participating sponsors provide a definition, resources, and funding for the projects.

They also commit a liaison from the sponsoring company to guide and support the

students throughout the academic year. Sponsors receive several benefits from the

Senior Design Program including a project completed by students and faculty

members. Additionally, the sponsoring company has the opportunity to work with

bright and enthusiastic individual with innovative ideas. This team experience is an

opportunity to evaluate senior students as prospective employees.

All projects are periodically

reviewed by faculty and the

Center’s Design Advisory Board

(DAB). The DAB is comprised of

engineering and computer science

professionals in both the private

and public sectors. They are

instrumental constituents for the

Center and a major factor in

guiding the students. The review

process br ings an outs ide

perspective to the projects and is a

component required to meet

design guidelines established by

the Accreditation Board for Engi-

neering and Technology (ABET).

Welcome to

Design Exposition Day 2014


Most Senior Design teams consist of three to five students and a faculty advisor who

work with a liaison from a sponsoring company. The students’ initial task is to generate a

plan and define strategies that will bring the project to fruition. Students must make

effective use of available resources to manage their project activities. Specific

milestones are identified, including

written reports and oral presentations.

Faculty advisors lend knowledge and

experience to each team with guidance

in the technical and managerial

decisions required by the project.

Liaisons help monitor team progress and

assist in making the best use of the

sponsor's resources and facilities. Several

projects (pp. 21-22) are multidisciplinary,

reflecting the importance of collabora-

tion across skills to solve real-world

problems.

In today’s world, wireless devices are becoming a necessity. Wireless technology, such as

magnetic resonance, is therefore increasingly relevant. The purpose of this project is to

demonstrate the effectiveness of magnetic resonance as applied to wireless power transfer. The

major challenge with this technology is the parasitic capacitance of the circuit, which can affect

the efficiency to the point of causing the technology to be unusable. By tuning the circuit, our

team aims to achieve optimal power transmission. We are studying and testing magnetic

resonance in order to explore the feasibility of this form of wireless power transfer.

Our team project was to create an embedded controller system for a battery-electric

winch that will be used to launch sailplanes. Changing the launch technique of sailplanes in this

way will increase the safety and decrease the cost per launch. Our team divided the project into

three main parts: the embedded system, simulations for the Host Controller and launch physics,

and detailed state machines. We have made significant progress toward a functional controller

system with a complete winch as our goal within a year. We also worked with another design

team, Glider Winch Host Manager (CPSC3), to unify each system development and complete

the overall project to be ready for use by soaring clubs as soon as possible.

Schweitzer Engineering Laboratories of Pullman, WA designed and developed a new 900

MHz radio for power distribution system automation. The purpose of our project was to perform

testing as part of the validation phase to determine the field performance of the radios under

real conditions. The tests involved Yagi and Omni-directional antenna configurations while

conducting path studies to ascertain appropriate links for the desired attributes. Part of our work

was to determine the effective range and receiver sensitivity, as well as design and test data

input. The ending result is a white paper with compiled test results, path theory, software tutorials,

and radio vernacular to benefit future SEL customers interested in this new wireless product.

The global forest products industry is broad and complex with thousands of lumber mills in the

United States alone, but buyers and sellers primarily communicate product inventories over email.

Furthermore, the industry has not adopted a single standard of measurement, which complicates

the process of locating lumber to purchase. Our project goal is to create a website that will

connect buyers and sellers in the industry. GoLumber will allow mills to post their lumber

inventories, which can then be located by potential buyers through a site search. GoLumber will

present the inventories so buyers and sellers around the world will be able to view lumber

inventories in desired units. The team is developing GoLumber using the Ruby on Rails Framework.

With an ever increasingly mobile customer base, Schweitzer Mountain Resort lacks a way

to bring together the customer community together in a competitive and engaging

environment. In order to tackle this problem, Schweitzer asked our team to create an iPhone

application for customers to use during their time on the mountain that will bolster the customer

experience. The mobile application includes four major features: tracking vertical feet skied and

other skiing statistics for each user, a leaderboard that ranks all users based on total vertical feet

skied, a social share function to post accomplishments on Facebook, and a push notification

interface with a built-in, up-to-date weather report for Schweitzer Mountain.

The goal of this project is to develop the host software for controlling an electric winch that

is efficient, cost effective, and easy to use. The winch, designed by George Moore, will be used to

launch sailplanes, a gliding aircraft often flown for sport. Currently, the process of launching a

sailplane is either inefficient or expensive. Our specifications are to write a user interface that will

allow a user to store and recall values regarding the pilot, sailplane, and location involved in a

launch, and then generate a launch according to those settings. The interface also needs to

provide real-time launch data for the operator of the winch. Our approach is a Java-based user

interface to take advantage of Java’s portability and usefulness in interface design.

Gonzaga University has many student resources and tools, but information about these

resources is often spread by word-of-mouth, crowded bulletin boards, or overpacked notification

emails. Zag Life, the GU student iOS app, streamlines university communication and student tools.

The three main tools implemented in Zag Life are an interactive campus map, a Who’s Who

directory of Gonzaga, and an event notification system. The campus map includes location

services, clickable buildings, and event and parking locations. The Who’s Who tab incorporates

all students, faculty, and staff through a secure sign in, as well as the ability to call, email, and

add a person to contacts. The events tab contains Gonzaga’s Zagtivities and event notifications.

The goal of this project is to create an expandable coil mandrel for Haakon Industries. The

current mandrels used are a set size. The mandrels damage the inside layers of the sheet metal

coils used and consume a significant amount of time to install. Haakon wishes to eliminate this

waste and shorten the installation time. We decided to create a mandrel with a pneumatic

expansion system that will fit into the middle of the coil and expand to hold the coil in place. The

new mandrel will fit the majority of the coils Haakon currently uses and will speed up the time to

change coils in the sheet metal cutting machine. They will also be easy to expand to fit the inside

of the coil with the simple connection of a pneumatic system.

Hanson Worldwide wanted to adapt the Combine Feeder System to be less expensive, to

handle higher loads, and to be more resistant to wear while maintaining the existing qualities of

the original, unbreakable product. To accomplish this, various material changes were made to

lower costs, improve strength, and decrease manufacturing time. Welds were replaced by bolts,

decreasing assembly costs without compromising the structure. The new design improved in the

wear resistance, verified through Finite Element Analysis, and the overall cost of the system was

reduced by 25%. The design was completed on time and put into production. Combines in the

Washington Palouse will be using the new design this summer in the wheat harvest.

The National Institute for Occupational Safety and Health Spokane Research Laboratory

sponsored this project to develop a portable sampler capable of collecting nano-scale airborne

particulate matter. The samples will be analyzed using electron microscopy to characterize

potential hazards to exposed workers. Using thermophoretic precipitation technology, our team

developed an efficient and portable design for the sampling device itself. Data collected from a

prototype testing session was used to advance the design toward efficiency, portability, and

usability. The Gonzaga team worked in partnership with an electrical engineering design team

from Eastern Washington University to develop the control systems.

Hydraulic systems in aircraft experience pressure transients which may be detrimental to

hydraulic tubes and components. Hydraulic accumulators are put into the system to absorb

these pressure transients. The Boeing Company sponsored this student project to design and build

a test stand to simulate pressure transients seen on Boeing aircraft in order to test the

effectiveness of a potential accumulator to be added to the plane. Students worked to procure

the proper components and design the test stand in order to fit the required specifications, tested

the accumulator and analyzed the data obtained from the testing procedure.

While solar panels are a great source of eco-friendly energy, stationary panels do not take

advantage of the total solar energy available. For this project, our team created a low-cost, solar

tracking system that would optimize the solar energy collection throughout the day and record

the accompanying data. Evaluating three different collection methods gave the means to

compare the total energy collected versus consumed. We compared single axis, dual axis, and

stationary designs. This design maximized the possible electrical output of a solar panel based off

these different configurations.

Texas at the end of April. Our team researched different types of off-road suspensions and

explored accessible manufacturing capabilities in consultation with our sponsor. We decided to

use dual trailing arms in the front of the car and single trailing arms in the rear of the car. The

design solution met SAE’s specifications to include all suspension arms, shocks, wheel hubs to

accommodate the clubs drive train, and attachment points on the frame.

Our team worked with UTC Aerospace to create a semi-automated solution for the loading,

unloading, and inspection process for the manufacturing of Carbon Disk Brakes on CNC lathes.

The current machining process requires a great amount of manual labor that creates an

unnecessary strain on the workers. By selecting a robotic arm from the available market,

designing a functional layout, and assessing the cost benefit of a semi-automated cell, the team

created an animated visualization of the proposed solution. Factors such as maintaining the grain

orientation of the discs and safety regulations were implemented into the final design. UTC

Aerospace will use the animation and a benefit analysis package to realize this process.

UTAS Spokane is a manufacturing plant that produces carbon brake disks used on aircraft

applications with a volume of around 75,000 parts a year. The goal of this project is to improve

UTC Aerospace’s brake disc disassembly process. The furnace tech’s poor ergonomic conditions

was the main problem addressed, as well as the dangerous practices used when separating

brake disc units. Our team provided a proof of concept for an alternative mechanical method

for the separation of the brake disc units. The alternative method adhered to Washington State

and UTC’s safety and ergonomic specifications, as well as the brake disc care requirements.

Our senior design project revolved around a Linux based program called LIGGGHTS

(Lammps improved for general granular and granular heat transfer simulations). FLSmidth, an

engineering firm that primarily focuses on mining technologies, sponsored this project. Our goal

was to run a simulation using Liggghts to recreate a previous test on a batch of material by

FLSmidth. To do this, we were required to learn how to use the Linux operating system while

simultaneously learning how to program in C++, which was both challenging and rewarding.

Ultimately, FLSmidth asked us to create an intuitive guide for the further use of this program inside

of their company.

Wagstaff is developing a new research facility with the capacity to cast larger aluminum

ingots. The company asked us to design a device that attaches to a crane and clamps to an

ingot (weighing up to 55,000 lbs.), allowing the crane to lift the ingot up and out of the casting pit.

As a team, we created a design that minimizes the overhead space needed and

accommodates a large range of ingot sizes. We developed a SolidWorks assembly and ran

engineering calculations to ensure the structural integrity and safety of the lifting device. While

designing, we accounted for overall weight, height, clamping speed, and clamping force. We

also specified and configured prefabricated components that were crucial to the design.

The project with Parker Aerospace is the development of an effective cooling system for

high heat load electronics. Specifically, there is a difficulty in distributing a two-phase fluid evenly

across an array of channels. The boiling fluid needs to be distributed evenly in terms of quality

and mass flow rate. This distribution is important because it is directly correlated to the

performance of the cooling system. We addressed this problem by designing and building a

refrigerant test loop capable of testing different distribution devices, which were assessed on the

basis of a temperature gradient across a set of heated channels. Parker will be able to use this

project for current and future designing of thermal management systems.

This project provides an open source for a cable drum as part of a system designed to

launch sailplanes. Other CEDE teams designed the control systems and drive. The design of the

drum needed to be lightweight, weather-resistant, cheap and easy to manufacture while

conforming to the sponsor’s numerical specifications. The rib-reinforced design is the result of a

series of refinement of four conceptual designs and the sponsor’s reference design. We

developed both shop and assembly drawings and a bill of materials that includes material and

finish specifications, as well as a cutting template for necessary parts and pieces. We used ANSIS

for stress calculations, and released the design with a 3-D license held by Gonzaga University.

FLSmidth’s existing mining equipment, the Mobile Stacking Conveyor (MSC) and Tripper

(MSCT), has limitations on its tractive power due to a reduced coefficient of friction as a result of

moisture, thus creating a low maximum incline angle. Our team developed a rack and pinion

concept that is retrofittable to the existing machinery and raised the maximum incline angle to at

least 14 degrees. To further present the concept, the team has produced a scaled model of the

Mobile Stacking Conveyor and Tripper, including the rack and pinion. The model is complete with

VFD control over the motion, as well as a gap between MSCs that the tripper needs to cross

without jamming the pinion, similar to the real machinery.

Our team collaborated with the Spokane Tribe of Indians with the project goal of building a

machine that can be used to automate the process of monitoring the fish caught from Lake

Roosevelt. The Fish Box is a two-year project that will count the number of fish in the creel, identify

the kind of fish, and measure weight/length of the fish. Our team, consisting of three mechanical

engineers and a computer engineer, designed a feed system, which consists of a centrifugal

system which feeds the fish one at a time to the vision system. The vision system is designed to

statistically compare the photo of the fish with stored profiles and identify the fish by finding the

closest match.

Bioinfiltration ponds are a common way to handle stormwater runoff, by filtration through

vegetation as well as infiltrating the water through soil to the groundwater table. Spokane County

has asked our team to develop a design to test the influent and effluent pollutant concentrations

in order to determine the effectiveness of bioinfiltration ponds removing target pollutants. In

Western Washington, the Department of Ecology requires municipalities to demonstrate that

stormwater best management practices (BMPs), such as bioinfiltration ponds, are functioning to

acceptable levels. This will be required in Eastern Washington in the near future and Spokane

County would prefer to have preliminary monitoring systems in place before it is required.

The Spokane Tribe of Indian Department of Natural Resources wants to construct a

spawning channel for fall Kokanee Salmon spawning in Enté Creek. The current creek houses

several degraded beaver dams which have filled in with sediment to create a swamp-like

environment at the mouth of the creek. The beaver dams themselves present major fish passage

barriers. In addition to the dams, the flow in the stream is too shallow for fish passage. We will

conduct an analysis to determine the current ecological health of the stream, as well as all

current barriers to fish passage. Streamline Solutions will then create a final design that the

Spokane Tribe of Indians can implement to restore Kokanee Salmon spawning to Enté Creek.

The Spokane Tribe of Indians contracted our team to help restore migratory Redband Trout

passage from the Spokane Reservoir through the drawdown zone and onto the spawning gravels

of Blue Creek. Currently, fish passage is limited due to low flow and no stream structure, which

decreases the depth and the increases velocity of the creek. With resources of faculty, computer

software, research, and local knowledge, our team proposed the development of an

engineered roughened stream channel with a pump. This combination should increase water

depths and decrease water velocities to an acceptable level for fish passage. By the end of the

2013-14 academic year, the Blue Creek senior design team will deliver project plans as well as

material and labor estimates to the Spokane Tribe of Indians.

The recorded concentration of Carbon Tetrachloride (CCl4) in the Freeman School District’s

Production Well, prior to treatment, exceeds the EPA’s maximum contaminant level of 5 parts per

billion. The goal for the project is to develop a treatment solution that would provide Freeman

School District with potable drinking water with reduced concentrations of CCl4. We evaluated

three active treatment alternatives, including Granular Activated Carbon, Air Stripping, and

Reverse Osmosis, and one passive alternative, constructing a new well outside of the

contaminated plume of CCl4. To evaluate which alternative was best fit for the needs of the

school district, we assessed the following criteria: feasibility, life cycle costs, maintenance,

operation requirements, and waste management.

Willow Creek Bridge is located southeast of Lake Coeur d’ Alene in Kootenai County, Idaho.

The Idaho Transportation Department (ITD) evaluated the existing bridge as structurally deficient

and in need of immediate replacement. Our project goal is to complete the design of a new

Willow Creek Bridge. Project scope includes completing a hydraulic study of the existing and

proposed bridges, a full structural design of the proposed bridge, and drafting all of our design

results in AutoCAD Civil 3D. The Hydraulic design involves sizing the bridge openings and channel

geometry in order to meet all FEMA floodplain and ITD regulations. The structural design includes

the substructure and superstructure, as well as foundations capable of supporting expected

traffic loads. The project scope also includes full roadway design to meet ITD standards.

Our goal is to provide comprehensive engineering efforts related to the

development of sustainable technologies to reduce the stormwater contribution to sewer flows

by treating runoff at residential sites in Spokane, Washington. Currently, Spokane relies on an

outdated combined sewer system that has been rendered illegal by extensions of the Clean

Water Act of 1972. The project entailed researching and testing low impact development (LID)

ideas to reduce stormwater runoff at the site. We researched rain gardens, bio infiltration

trenches, porous material, and dispersion as alternative solutions. The team created conceptual

designs, decision matrices, and a cost analysis of the specified alternatives. The City of Spokane

will use these deliverables to evaluate stormwater options throughout the city.

Our goal was to complete the design and structural drawings for the Bridger Bowl Ski Lodge

in Bozeman, Montana. Eclipse Engineering, the sponsor company for the project, provided the

architectural drawings for the ski lodge, which is an already existing structure. Our task was to use

these architectural drawings and create a preferred structural design for the lodge. Our team

considered all applicable loads in the structural design, including dead, live, snow, wind, and

seismic loads. We have completed a design of all structural components, including the

foundation, structural members, and connections. Standard civil engineering references,

codebooks, and design guides were used during the design and analysis process to ensure that

all necessary structural specifications were met. Our team utilized our structural and geotechnical

abilities to examine design options to ensure a low cost and sustainable design solution.

Located in a rural and impoverished region of India, Padhar Hospital and MSAADA, a

Our project is to complete the structural assessments of two of Gonzaga University’s

existing buildings, DeSmet Hall and the Crosby Student Center. Our project scope included a

feasibility study of multiple proposed changes to the buildings. As a team, we analyzed DeSmet

Hall and Crosby Student Center with a Tier 1 Seismic Evaluation, identifying both existing and

potential deficiencies within the structural systems of the buildings while offering the client

recommendations of rehabilitation. We accomplished these studies through the use of current

codes and structural calculations to determine if the proposed changes could be applied to the

buildings while maintaining a life safety priority.

To address a shortage of skilled tradespeople in the Spokane area, Spokane Community

College selected Integrus Architecture and our team to design a new training center for skilled

tradespeople. Integrus provided the architectural design while our civil design team focused on

developing a structural system for the building. After consulting with the architect and evaluating

structural systems, we selected and designed a system composed of steel braced frames to

satisfy lateral force resistance requirements. The gravity framing system consists of exposed

wide-flange steel beams, girders and roof joists, satisfying the architect’s request to expose as

much of the structure as possible. Other structural elements such as roof decking, columns, and

foundations were designed around the steel braced frames.

abandoned because they exceed the taste threshold for chloride. Future groundwater

development must be managed so long-term threats to water quality are minimized while the

rate of water production remains sufficiently high to serve the population. Our team developed a

calibrated groundwater management tool with a user manual that demonstrates how to modify

the model. This management tool allows agency personnel to assess the impact of present and

future water development strategies. The tool also allows agency personnel to determine the

flow pathways of groundwater under various well location and pumping discharge scenarios.

A portion of Downtown Spokane’s electrical grid, the Metro East Network, is nearing full

capacity. With load increases expected, reliable service near the network’s edges may be

difficult to provide. Currently three feeders run from the Metro substation to the Metro East

network. Avista Utilities asked us to design a fourth feeder to remove stress from the other three

feeders and increase capacity. Adding additional cable underground poses problems from a

heat-transfer perspective, so a significant portion of our efforts were spent analyzing the network

from a thermal point of view. Our proposal will keep Downtown Spokane powered while

maintaining the safety and reliability of an electrically robust and mechanically sound network.

Our team worked with EWU Department of Communication Disorders and The Parkinson’s

Resource Center of Spokane to build a Parkinson’s Voice Monitor. Our product is designed for use

in medical practices, as well as, daily life. The voice monitor uses a sensor to obtain the vibrations

of the larynx to determine if the user is speaking at a level that is clear for others around them. If

they are speaking below this level, the user is notified. This device will help speech therapist and

families to improve communication with individuals with Parkinson’s disease. To create this

device, we brought our individual electrical and mechanical disciplines together. Writing code to

be used by an Arduino Uno, this device works collaboratively with our student-designed circuit

board to read, store, and give an output from the data that is obtained through the sensor.
