With the recent advancements in High Performance Computing (HPC), it is possible to rapidly process high volumes of data, allowing accomplishments in several areas of knowledge. Although the HPC area has been observed as an area of complex infrastructure, in the last years, its been observed that the processing power of processors used in embedded systems, using the ARM architecture, has been increasing significantly. Furthermore, the acquisition costs and energy consumption are lower, when compared to processors of other platforms, thus allowing for the possibility of having HPC with smaller and more economical platforms, with lower maintenance cost and more accessible. In this merit, this masters thesis proposes the performance analysis of a low cost embedded cluster composed of processors using ARM architecture and the Raspberry Pi platform. This work analysis the impact of using MPICH-2 and OpenMPI libraries, running benchmark programs HPCC and HPL. The present work show results of performance and energy consumption of this cluster with these programs, proving that it is possible to use clusters of low cost embedded platforms with satisfactory speedups and energy consumption. / Com o desenvolvimento da computação de alto desempenho (HPC), grandes volumes de dados passaram a ser processados de forma rápida, permitindo assim, que avanços significativos fossem alcançados em varias áreas do conhecimento. Para isso, sempre se observou a área de HPC tendo uma infraestrutura complexa. Por outro lado, nos últimos anos, se observa que a capacidade de processamento dos processadores usados em sistemas embarcados, seguindo arquitetura ARM, vem aumentando de forma significativa. Além disso, os custos de aquisição e o consumo de energia dos processadores ARM são menores, quando comparados a processadores de outras plataformas. Neste âmbito, cria-se a possibilidade de ter HPC usando plataformas menores e mais econômicas e com um custo de manutenção mais acessível. Nesse intuito, esta dissertação de mestrado, propõe a análise de desempenho de um cluster embarcado de baixo custo composto por processadores da arquitetura ARM e plataforma Raspberry Pi. O trabalho analisa o impacto de usar as bibliotecas MPICH-2 e OpenMPI, executando os programas dos benchmarks HPCC e HPL. O trabalho apresenta resultados de desempenho e consumo de energia do cluster com esses programas, mostrando que é possível usar clusters de plataformas embarcadas de baixo custo e tendo speedups e consumo de energia satisfatórios.

The use of Intrusion Detection Systems is a normal thing today in bigger companies, butthe solutions that are to be found in market is often too expensive for the smallercompany. Therefore, we saw the need in investigating if there is a more affordablesolution. In this report, we will show that it is possible to use low cost single boardcomputers as part of a bigger centralized Intrusion Detection System. To investigate this,we set up a test system including 2 Raspberry Pi 3 Model B, a cloud server and the use oftwo home networks, one with port mirroring implemented in firmware and the other withdedicated span port. The report will show how we set up the environment and the testingwe have done to prove that this is a working solution.

Bosch Rexroth in Mellansel is manufacturing hydraulic motors and constantly trying to improve their products to reduce downtime for their customers. An important thing to get a reliable system is to know the condition. In a hydraulic motor, it is crucial to determine the particle contamination of the oil to determine the condition. To do so many particle sensors have been tested by Bosch Rexroth but also other related companies during the past years. To this point, no sensor has been performing good enough to replace the ordinary magnetic plug for the laboratory tests at Bosch Rexroth.  The ordinary magnetic plug is based on an openable lid that has a magnet attached to it. The lid is opened to review the particle contamination of the system. To open the lid the motor has to be stopped and a competent person needs to be present to review the particles.To ease the work for the laboratory personal and also getting one step closer to a reliable condition monitoring solution a new idea was coined by employees at Bosch Rexroth. The idea was to use a magnet outside a glass disc and by that be able to detect the particles from outside the motor. Initial testing of the idea had been performed with promising results but more development was needed. The idea has therefore been investigated and developed further in this project. This has been done in parallel with an investigation of state-of-the-art techniques available on the market. The testing showed that the new type of magnet/glass solution was performing well and was able to detect particles of different sizes. Some other interesting options were also found during the investigation of other techniques but the new magnet/glass idea was the most prominent.

Automatic Passenger Counting (APC) systems are some of the many Internet-Of-Things (IoT) applications and have been increasingly adopted by public transportation companies in recent years. APCs provide valuable data that can be used to give an real time passenger count, which can be a convenient service and allow customers to plan their travels accordingly. The provided data is also valuable for resource streamlining and planning, which potentially increases revenues for the public transportation companies. This thesis briefly studies and evaluates different APC technologies, highlights the advantages and disadvantages of these, and presents an Edge-prototype based on Computer Vision and Object Detection. The presented APC was tested in a lab environment and with recordings of people walking in and out of a designated area in the lab. Test results from the lab environment show that the presented low-cost APC efficiently detects passengers with an accuracy of 98.6% on pre-recorded videos. The APC was also tested in real time and the results show that the low-cost APC only achieved an accuracy of 66.7%. This work has laid the ground for further development and testing in a public transport environment.

This thesis focuses on Internet of Things (IoT) and open-source technologies based on it. Specifically aims at software solutions relevant to smart home and compatible with Raspberry Pi platform and MQTT communication protocol. This thesis also focuses on studying Petri Net Virtual Machine (PNVM) and its potential application in IoT. The objective is to design integration of PNVM into IoT with help of existing software means compatible with MQTT and implement a demo application for smart home.

This thesis deals with design, development and testing of device for collecting fly data in ultralight airplane or helicopter. The basic collected value is a count of fly hours of each pilot. Additional fly data are latitude, longitude and altitude. Purpose of this device is a fair pricing for use of the airplane. Another utilization is in analysis of flight path or in pilot training. This device is succesfully made from miniature computer Raspberry Pi and uses GPS data. A reader will be informed about aviation regulations, embedded systems, global positioning system and wireless internet connection.
