1st zone : Entrance - Information

The entrance is marked by a semicircular arch that welcomes the visitors and defines a wide square that is an outdoor meeting space. Three parallel rectangular geometries mark the beginning of the course and lead the visitors to the central axis. A metal mesh unites the forms and a flat surface rams the volumes vertically, joining them.

2nd zone : Art - Science

Two identical volumes host art and science activities. They start alongside and are synthetically united in their extremity. A sloping metal roof - the roof of Arts and Sciences- crowns the two architectural forms. Two parallel volumes accommodate rural activities.An aqueous strip connects the volumes with the main composition.

Design Centre at the coastline of ThessalonikiAcademic project

Aristotle University of Thessaloniki

The idea of the composition de-rives from the concept of the magnet, ie a center that will at-tract people, ideas, crafts and activities. Spatially the idea was translated in a building - pole that tows cubes, the primary unit of the synthesis, which are convert-ed to spaces closed , semi-open and open . The access to the centre is either through the air, by the overhead crane located in the path of the beach or by sea, from the pier, as we wanted to empha-size this attraction at all levels . The sides of the structure are formed with different skins, mate-rials, textures and colors in order to give diversity to the center de-sign, creating a live attraction for citys residents.The design of the platform fol-lows the logic of abstraction of the cube. The concept arose from a grid from which units were re-moved, giving the final form.

Landscape DesignPapafis Stream - Academic Project

Aristotle University of Thessaloniki

the main goal was the design of multiple connections on both sides of the stream as well as open spaces for the visitors to enjoy the nature. All the trees that existed in the area were kept and more were added in a natural combination. In addition, a playground and a small amphitheater were designed at both ends of the path.

EcoME CentreGroup project in EcoWeek 2011 in Thessaloniki

EcoMe ( Eco Middle East) is a model of environmental, social and personal sustainability in the Middle East. It is located in the Judian desert of the North Dead Sea in Palestine so that it is ac-cessible to Israelis & Palestinians, with no permits. The project ap-proach was to identify the nutrient and energy circles and close the loops by decentralising energet-ic input and output. This includes the use of local materials and skills, the minimisation of energy and water needs, the use of so-lar energy and rainwater and the treatment and reuse of grey water and waste.

For the design of the enclosed spaces a local technic was im-plemented, the Gabion Wall. This wall is essentially a metallic cage that is filled with rocks of any size that are found in the area. Another material used for space partition are plam leaves that are found in abundance in the area. For shel-tering purposes, beduin tents and metal panels are used, all under the goal to achieve a sustainable design.

Urban DesignVersions of Cohabitation - Academic Project

Aristotle University of Thessaloniki

The term of cohabitation refers to the space where the need for social interaction (random or on purpose) is gathered. Cohabita-tion is a platform of various uses taking place, where either it con-tains traction or repulsion, action and reaction, all transformed by social powers, above or below the ground.

Clusters of the cityClassification of neighbourhoods through quantifiable spatial attributes

MSc dissertation

This project is a comparative analysis of three areas within London based on measurable attributes of each city block, to assess the degree to which characteristic differences between the neighborhoods are evident and quantifiable. Samples were taken from the three neighbourhoods of East Dulwich, Pimlico and the City of London, measuring both the street network and of the geometry of buildings within the block. All samples were compared using principal components analysis (PCA) and linear classifiers to determine the degree to which samples from each neigh-bourhood fell into clearly distinct clusters, and the relative contribution of the types of measures to these classifications.

Pimlico East Dulwich City of London

Results show a clear distinction in attributes between the three areas. Using the combination of morphology and street measures, integration and to a lesser degree choice dominate the analysis, clear differences are revealed between the two residential neighbourhoods with an almost 100% classification.

Human - Machine InteractionA machine learning approach to dance improvisation for robot interaction and performance

Academic Project

With the use of a Kinect sensor and Processing, the body of a dancer is tracked, and the human body joints are represented as vectors. For the control of the UR 10 robot, Grasshopper is used.

screenshot of the final performance

The specific project is an ap-proach to examine robot and human interaction through kine-matic conversations with dance as an example. With the use of algorithms, robotic improvisa-tion is questioned. Three differ-ent methods were implemented.First is a pre-choreographed per-formance with random display of movements by the robot. Second is a supervised machine learning approach with an Artificial Neural Network. The final method that was implemented is a statistical approach with average values.

The robot, through a Kinect sen-sor, perceives information of the angles that are created by the hu-man dancers arms and adds the values to a gesture library. In real time interaction, the robot either displays already known gestures or it records the average angle values of live gestures and adds them to the library. It was consid-ered the most successful method among the three, and was there-fore, tested in a performance. The performance was recorded and presented in a small group of peo-ple. Through a small survey that was conducted, the results were encouraging.

Real Time Data FeedbackForm Creation based on human movement simulation

Academic Project

perspective view of the final structure

pseudocode

This project is an approach to un-derstand how pedestrian behav-ior could affect the surroundings and more specifically a structure meant for sheltering purposes. Having Carnaby Street as a visu-al environment layout, pedestrian behavior is simulated by agents.The agents positions are record-ed and grouped with the use of a k-means clustering algorithm.The centroids of the clusters serve as nodes of a mesh structure.For the creation of the structure simple rules were followed, depending on the previously collected data. 5 additional nodes are added with specific coordinates, that serve as the support points of the struc-ture. The height of the nodes is affected by the number of points that are assigned to each cluster (the more points the higher the node). The nodes are connect-ed together within a predefined distance. The distance between the nodes affects the weights of the connecting lines, result-ing to a structure that is dense in points of higher congregation and lighter at areas with less.

AerobotFlights of Fancy- Physical Computing Workshop

UCL - October 2013

The Aerobot is a cardboard robot that shoots paper planes. It uses an Arduino board to function. To aquire target, it can rotate in 2 di-rections. with the use of 2 servos ( servomechanisms), a.k.a. auto-matic devices that provide posi-tion control. The robot aims either manually, with a controller or au-tomatically, through a webcam. For the latter, a code was written in Processing.

The firing mechanism is activated manually through the controller. First, a button is pressed. Then the loading wheel is rotated until the LDR sensor senses light from a LED through a hole in the wheel. The rotation results to the plane touching the launching wheel, that has rubber ends and there-fore resulting to the launch of the paper plane.
