The diploma thesis goes through the various phases of design and development software using the Open Unified Process methodology and its subsequent processing using UML. The outputs from the analytical and design parts are then used to implement a custom registration system. This paper describes and compares several methods currently used in software development and introduces the reader to the basic principles of object-oriented programming. It provides an overview of the components and principles of processing framework Qt 5, the SDK development environment and the consequences resulting through practical uses when developing applications.

This master's thesis deals with the design and implementation of universal user interface for detection devices used in Laser-induced breakdown spectroscopy. The design and implementation are based on analysis of current state of instrumentation used in laser spectroscopy. The user interface should be able to work with high repetition frequency of measurement. Acquired spectra should be visualised to user and it is also necessary to save this data on hard drive. The resulting application must be universal. It means the application must support various types and vendors of detection devices.

The BlackPearl in the Computer Engineering Department is an Automotive Demonstrator, which has a variety of sensors, and users can control these via the server. The server is responsible for the remote interaction, the Smart Queue, and the Raspberry Pi display for human interaction. The Automotive Demonstrator consists of four components, which are installed on the CE-Box: Main QML Application, Main Server, Live Stream, and Smart Queue. All of these servers are running on three single-board computers (Raspberry Pi 3B): Main, BlackPearl, and Camera servers. The Automotive Demonstrator is built with the latest version from both Qt and NodeJS, and the components can access, store and exchange the data in JSON format. The BlackPearl will be controlled via four types of interaction methods: Web server, Voice commands (Sparrow), Pi Display, and Gamepad. The outcome of this thesis is a configurable and adaptive User Interface for Automotive Demonstrator, and this can be easily updated, customized, and accessible for new applications without the need to update or rebuild the program.

Ce document traite du problème de la grande dimension dans des processus GARCH multivariés. L'auteur propose une nouvelle dynamique vine-GARCH pour des processus de corrélation paramétrisés par un graphe non dirigé appelé "vine". Cette approche génère directement des matrices définies-positives et encourage la parcimonie. Après avoir établi des résultats d'existence et d'unicité pour les solutions stationnaires du modèle vine-GARCH, l'auteur analyse les propriétés asymptotiques du modèle. Il propose ensuite un cadre général de M-estimateurs pénalisés pour des processus dépendants et se concentre sur les propriétés asymptotiques de l'estimateur "adaptive Sparse Group Lasso". La grande dimension est traitée en considérant le cas où le nombre de paramètres diverge avec la taille de l'échantillon. Les résultats asymptotiques sont illustrés par des expériences simulées. Enfin dans ce cadre l'auteur propose de générer la sparsité pour des dynamiques de matrices de variance covariance. Pour ce faire, la classe des modèles ARCH multivariés est utilisée et les processus correspondants à celle-ci sont estimés par moindres carrés ordinaires pénalisés. / This document contributes to high-dimensional statistics for multivariate GARCH processes. First, the author proposes a new dynamic called vine-GARCH for correlation processes parameterized by an undirected graph called vine. The proposed approach directly specifies positive definite matrices and fosters parsimony. The author provides results for the existence and uniqueness of stationary solution of the vine-GARCH model and studies its asymptotic properties. He then proposes a general framework for penalized M-estimators with dependent processes and focuses on the asymptotic properties of the adaptive Sparse Group Lasso regularizer. The high-dimensionality setting is studied when considering a diverging number of parameters with the sample size. The asymptotic properties are illustrated through simulation experiments. Finally, the author proposes to foster sparsity for multivariate variance covariance matrix processes within the latter framework. To do so, the multivariate ARCH family is considered and the corresponding parameterizations are estimated thanks to penalized ordinary least square procedures.

This report describes the development process of the mobile application HealthyWay. The application is developed as a Bachelor thesis project together with KTH Royal Institute of Technology. The applications' main function is to be the interface to a number of wearable medical electronic appliances such as bandages and pill boxes. The communication is done through Bluetooth Low Energy. The application was mainly written in 3 di erent languages, QML, C++ and Java. The most stressed point throughout this project was the importance of platform independence. The exibility had to be done on a scalable as well as on a modular level. With this in mind, QT was used to address the requirement of scalability. The modularity was achieved through an organized structure to the program accompanied by easy directives to introduce new devices. The purpose of the application is to increase the quality of life for the user. This intent could however not be concluded due to the lack of testing among users. In its current state, the application is not yet ready for deployment but instead acts as a framework for future prospects. / Den här rapporten beskriver utvecklingsprocessen för en mobilapplikation vid namn Healthy- Way. Applikationen är utvecklad som ett kandidatexamensarbete tillsammans med KTH. Applikationens huvudsakliga uppgift är att vara ett gränssnitt till medicinskt relaterad utrustning såsom plaster och pilleraskar. Kommunikationen mellan dessa sker via Bluetooth Low Energy. Applikationen skrevs huvudsakligen i 3 olika språk, QML, C++ och Java. Den viktigaste punkten genom projektets gång var att applikationen skulle vara oberoende av plattform. Flexibiliteten var tvungen att göras på både en skalbar och modulär nivå. Med detta i åtanke valdes QT för att behandla skalbarheten. Modulariteten uppnåddes genom en välplanerad struktur på programmet tillsammans med instruktioner på hur ny utrustning kan introduceras. Syftet med programmet är att öka livskvaliteten för användaren. Detta syfte kunde däremot inte slutföras på grund av bristande testning hos användare. I dagens läge är applikationen inte redo för att släppas kommersiellt, men tjänar som ett bra ramverk för framtida utveckling.

A highly accurate sensor for measuring distances, used for creating high-resolution 3D maps of the environment, utilize “Light Detection And Ranging” (LiDAR) technology. This degree project aims to investigate the implementation of 3D LiDAR sensors into off-highway vehicle display computers, called CCpilots. This involves a study of available low-cost 3D LiDAR sensors on the market and development of an application for visualizing real time data graphically, with room for optimization algorithms. The selected LiDAR sensor is “Livox Mid-360”, a hybrid-solid technology and a field of view of 360° horizontally and 59° vertically. The LiDAR application was developed using Livox SDK2 combined with a C++ back-end, in order to visualize data using Qt QML as the Graphical User Interface design tool. A filter was utilized from the Point Cloud Library (PCL), called a voxel grid filter, for optimization purpose. Real time 3D LiDAR sensor data was graphically visualized on the display computer CCpilot X900. The voxel grid filter had a few visual advantages, although it consumed more processor power compared to when no filter was used. Whether a filter was used or not, all points generated by the LiDAR sensor could be processed and visualized by the developed application without any latency.

Esta Tese aborda, de modo original e pioneiro, importantes aspectos da Engenharia de Fundações do Sul de Minas: a) sistematização de conhecimentos sobre a Geologia regional; b) identificação e caracterização da prática de fundações; c) definição (com a formação de um banco de dados) dos perfis mais representativos do subsolo de suas principais cidades; d) estudo dos parâmetros físicos, químicos e geomecânicos de um solo típico; e) implantação de campo experimental de fundações da Universidade Federal de Lavras, com a realização de provas de carga. Grande ênfase foi dada aos itens (a), (c) e (e). Priorizou-se o estudo das fundações de baixa capacidade de carga, no estudo do comportamento carga-recalque de ensaios de placa, de provas de carga a compressão em estacas-broca isoladas e de tubulões curtos instrumentados. Destacam-se as análises sobre os efeitos de forma, profundidade, melhoramento do terreno de fundação e de inundação nas fundações rasas e da variação L/d na resistência lateral unitária das estacas, sendo valorizadas as fórmulas empíricas com base no SPT. São apresentadas fórmulas de previsão de carga, em função do SPT, para sapatas, estacas de pequeno diâmetro e tubulões curtos e um estudo de custos, onde se mostra que a opção indiscriminada por tubulões é inadequada para certas faixas de carga de trabalho. Adicionalmente, são feitas recomendações para intensificar o uso de sondagens tendo em vista a grande variabilidade das propriedades dos solos regionais e para aumentar os fatores de segurança nestas fórmulas onde houver possibilidade de ocorrência de colapso no solo. / This work presents, at time, important aspects of Foundation Engineering at Southern Region of Minas Gerais State: a) systematization of the knowledge about regional geology; b) identification and characterization of practice in foundations; c) definition (though establishment of a data base) of most representative sub-soil profiles at main cities at the region; d) study of physical, chemical and geomechanical parameters of a typical soil; e) implementation of a experimental field for foundation studies at Federal University of Lavras, by execution of load tests. A large emphasis was given to items a, c and e. The study of foundations of low load capacity was prioritized when testing plates, isolated piles under compression and short drilled piers with sensors. Analysis such as form effects, depth, soil improvement and flooding on shallow foundations and variation of L/d on the lateral unity resistance by emphasizing the empiral equations based on SPT were all pointed out. Mathematical equations are presented for load estimation as function of SPT for small diameter piles and short drilled piers as well as a cost study where it can bem shown that the undistinguished alternative for piers is inadequate for some load values. In addition, due to soil spatial variability and safety factor increment on soils subject for colapse, recommendations on intensive use of SPT test are given.
