Context & Objectives
Digital twins are virtual replicas of physical devices and they can be used to run simulations before actual devices are deployed or to prevent potential failures. At CIMSOLUTIONS there is a Digital Twin Competence Center, which works on the concept idea of the creation of a Digital Twin Dashboard. The intention of this Dashboard is to become the digital copy of a Raspberry Pi Auto-vehicle. More specifically, a Raspberry Pi mini-car with connected sensors regarding its dynamics (such as speed, acceleration, wheels rotation, etc) and its environment (such as temperature, humidity, etc) communicates with a base station. The base station implements a Dashboard where the user can see the environmental parameters and the dynamics of the vehicle. As a result, this work focused to implement the most accurate version of this mini-car representation in the Dashboard.

Results & Added value
My role in this project was to assemble the SunFounder PiCar-S, attach the Raspberry Pi on top of the car, and connect all the sensors to the Pi interface. In addition, I installed all the libraries to enable our software to read the data from the sensors, and with the use of Python, I have achieved to establish a data stream between the car and the base station. This data stream is the actual data representation of the current state of the car in terms of speed, wheels rotation, wheels angle, and direction. These values are used from the Dashboard and implemented as a whole the digital twin of the mini-car. This specific Dashboard is a virtual representation of the mini-car and can predict potentials threats in real-time time. For example, if the car makes a turn and the rotation speed of the left front wheel is different from the rotation speed of the right front wheel, then there is a potential danger such as under-steer or over-steer.

Context & Objectives
The Netherlands has, along with Austria, the best waste management program in Europe, according to a recent report from the European Commission [https://europa.eu/rapid/press-release_IP-12-888_en.htm?locale=en]. However, after a walk in Eindhoven's city center, you are more likely to get depressed and angry at the sight of other people’s rubbish, from casual litter to deliberate fly-tipping. While littering of the oceans is now at the forefront of public concern, general littering of the countryside and communities is barely on the national radar. Yet the amount of “eyesore” litter, not just plastic, is increasing exponentially on roadsides, in rivers, in public spaces, and in the countryside and has a hugely negative impact on people’s lives. The proactivity and personalization of the services should be the action guide of the public function in the very near future, and as a result municipalities are vital to this new era.
This project focused on the concept idea of the creation of an autonomous flying drone, which could help the authorities to keep the cities clean. A drone that could fly alone in the city, recognise all the garbage in the streets and then sends a heatmap to the authorities about where they should clean today.

Results & Added value
The outcome of this work is in the form of a Matlab script, which receives the coordinates of a specific location and commands a drone to scan this specific area for garbage. More specifically, the drone will fly in a pattern which has been imported from Matlab, covering the whole area and it will take real-time images for classification. Once the whole area is scanned drone will return to the base and a report will be generated with all the information about its flight, the covered area and the garbage, which has been found.

Context & Objectives
The aviation industry has a considerable need for exchanging effective, global communications on a daily basis. SITATEX IP is the leading operational mail service in the air transport industry (ATI). It generates and receives ATI-specific Type B messages through an intuitive mail interface. Over 20,000 users in the ATI, across 200 countries and territories, exchange over 800 million messages every year with SITATEX IP. Eindhoven airport communicates with the rest of the airports and with the airlines via this component, which has a cost per message. As a result, there is a need for a budget for communication and back-up purposes.

Results & Added value
The output of this project is an add-on, which simplifies the back-up process and reduces the cost of messaging. More specifically, my solution concluded a cost reduction per year for Viggo Eindhoven Airport. Moreover, a 24/7 email daemon has been created, which operates real-time and extracts all the relevant to Operations info from the incoming Type B Messages at Eindhoven Airport. This extraction can be achieved only by Advanced Airport Distributed Control System and as a result, with the use of this tool, Viggo Eindhoven Airport negotiate the condition with their customers being in an advantageous position.
