This thesis tackles the challenge of real-time image analysis in resource-constrained embedded systems, focusing specifically on Micro Aerial Vehicle (MAV) applications. The primary objective of this research is to design a software architecture that integrates features like modularity, real-time capabilities, robustness, and adaptability to meet the demands. The study proposes a unique software architecture based on blackboard and microservices architectures, that facilitates the key strengths from both paradigms, while mitigating their individual limitations. Additionally, it leverages shared memory inter-process communication mechanism for implementing centralized knowledge base of the blackboard, and realizing the API of the microservices architecture. The computer vision system tasks are decomposed into smaller pieces, and developed and implemented as loosely coupled individual software components. The thesis contribution lies in an efficient architecture for real-time image analysis on safety-critical and resource-constrained MAV platforms. The architecture provides an efficient and real-time-capable backbone and offers modularity and reusability for diverse applications.:1. Introduction 2. Fundamentals 3. Literature Review 4.

It is also fact, in today s society, the need of carrying out tasks and solving problems in a collaborative way. As an example, one can cite the qualitative research which, when performed with the aid of computers, can make use of CAQDAS (Computer Assisted Qualitative Data Analysis Software) applications. Although it is possible to perform qualitative analysis within CAQDAS applications in isolation, the study/work performed by a group has the differential to enable the interaction among members of a team and provide the expression of different points of view and opinions, besides being more likely to comments and criticisms that help improve the quality of the work. Thus, this document presents WebQDA, a collaborative tool that uses the basic features of qualitative data analysis with the aim of illustrating how Web 2.0 new concepts can affect productivity in qualitative research by working in a cooperative way. / É inegável a importância dos ambientes colaborativos no mundo globalizado, seja para possibilitar o compartilhamento de informações ou tornar possível a interação entre pessoas distantes. Também é fato, na sociedade atual, a necessidade de realização de tarefas e solução de problemas de forma colaborativa. Como exemplo, pode-se citar a pesquisa qualitativa que, quando realizada com o auxílio do computador, pode fazer uso dos aplicativos CAQDAS (Computer Assisted Qualitative Data Analysis Software). Apesar de ser possível realizar análises qualitativas em aplicativos CAQDAS de forma isolada, o estudo/trabalho realizado por um grupo possui o diferencial de permitir a interação entre os membros de uma equipe, possibilitando a expressão de pontos de vista e opiniões diferentes, além de ser mais propenso a comentários e críticas que contribuem para a melhoria e qualidade do trabalho. Desse modo, este documento apresenta o WebQDA, uma ferramenta colaborativa que utiliza as funcionalidades básicas da análise qualitativa de dados, visando ilustrar como os novos conceitos da Web 2.0, como redes sociais, podem afetar a produtividade na pesquisa qualitativa ao se trabalhar de forma cooperativa.

In 2012, falls from elevation in construction industry represented 36% of the total fatalities. The Occupational Safety and Health Administration requires workers to use fall protection systems where workers are 6 feet or more above a lower level. Anchors for fall protection systems attached to roof trusses may cause out-of-plane loading on these structures. Metal plate connected wood trusses (MPCWT) are not designed to carry out-of-plane loads and MPCWT performance under these loads are not evaluated in the design process. The goal of this research is to model and analyze MPCWT assemblies under out-of-plane loads. The rotational stiffness of truss-wall connections, and truss bracing elements are included in the structural component model. Previous experimental data of fall arrest anchor loading were used for model validation. A parametric study considering loading location, joint stiffness and dimension of trusses was conducted. The structural analog of the MPCWT assemblies were found to have first truss deflections within 4% difference, thereby the models were validated. From parametric study results, the load location was not changed the ultimate deflection in the truss assembly by maximum value of 9%. Out-of-plane joint stiffness was the parameter that caused a large difference in the deflection results, when the joists were assumed as either rigid or simple connections. The rotational stiffness of lateral and diagonal bracing should be included as model inputs for the accurate representation of experimental behavior. Truss lengths increased the deflection at the top chord of the first truss in the assembly as truss width increased. / Master of Science

Simulating the human heart is a challenging problem, with simulations being very time consuming, to the extent that some can take days to compute even on high performance computing resources. There is considerable interest in computational optimisation techniques, with a view to making whole-heart simulations tractable. Reliability of heart model simulations is also of great concern, particularly considering clinical applications. Simulation software should be easily testable and maintainable, which is often not the case with extensively hand-optimised software. It is thus crucial to automate and verify any optimisations. CellML is an XML language designed for describing biological cell models from a mathematical modeller’s perspective, and is being developed at the University of Auckland. It gives us an abstract format for such models, and from a computer science perspective looks like a domain specific programming language. We are investigating the gains available from exploiting this viewpoint. We describe various static checks for CellML models, notably checking the dimensional consistency of mathematics, and investigate the possibilities of provably correct optimisations. In particular, we demonstrate that partial evaluation is a promising technique for this purpose, and that it combines well with a lookup table technique, commonly used in cardiac modelling, which we have automated. We have developed a formal operational semantics for CellML, which enables us to mathematically prove the partial evaluation of CellML correct, in that optimisation of models will not change the results of simulations. The use of lookup tables involves an approximation, thus introduces some error; we have analysed this using a posteriori techniques and shown how it may be managed. While the techniques could be applied more widely to biological models in general, this work focuses on cardiac models as an application area. We present experimental results demonstrating the effectiveness of our optimisations on a representative sample of cardiac cell models, in a variety of settings.

<p>Almost any large-scale system can be viewed as a network that shows interac-tions among entities which are constituent parts of the system. The focus of this<br />dissertation is on complex networks from three domains: (1) networks extracted<br />from source code of computer programs that represent design of software systems,<br />(2) networks extracted from semantic web ontologies that describe the structure<br />of shared and reusable knowledge, and (3) networks extracted from bibliographic<br />records that depict collaboration in science. We proposed new methods for the<br />extraction of networks from mentioned domains. Secondly, on several case stud-ies we demonstrated benets of network-based analysis of concrete systems from<br />those domains. In contrast to the previous work on the subject, analyses pre-sented in this dissertation are not purely topological, but combine techniques and<br />metrics developed under the framework of complex network theory with domain-dependent metrics.</p> / <p>Skoro svaki kompleksan sistem se može predstaviti mrežom koja opisuje interakcije izmedju entiteta od kojih je sistem komponovan. Fokus ove disertacije je na&nbsp;kompleksnim mrežama iz tri domena: (1) mreže ekstrahovane iz izvornog koda&nbsp;računarskih programa koje reprezentuju dizajn softverskih sistema, (2) mreže ekstrahovane iz ontologija semantičkog web-a koje opisuju strukturu deljenog znanja&nbsp;pogodnog za vi&scaron;ekratnu upotrebu, i (3) mreže ekstrahovane iz bibliografskih zapisa koje opisuju saradnju istraživača. U okviru disertacije predložene su nove&nbsp;metode za ekstrakciju mreža iz pomenutih domena. Drugo, na nekoliko studija&nbsp;slučaja ilustrovani su beneti mrežno orjentisane analize konkretnih sistema iz&nbsp;domena obuhvaćenih disertacijom. U poredjenju sa prethodnim relevantim istraživanjima, analize prezentovane u disertaciji nisu čisto topolo&scaron;ke, nego kombinuju tehnike i metrike razvijene u okviru teorije kompleksnih mreža sa metrikama iz konkretnog domena.</p>

Requirements Engineering and Software Quality Management is nowadays considered to be one of the important parts of the software development process. This thesis deals with connecting the theoretical concept of requirements engineering and usage of functions offered by Enterprise Architect tool, which should support the requirements engineering and software quality management processes. The main goal is to propose procedures of Enterprise Architect usage during the project in such a way, which will help to raise quality of the final product. The purpose is to offer a systematic and conscious way of implementation Enterprise Architect elements into software development processes, because this tool is able to support the whole cycle of the product. The methodology was designed as a result of theoretical concept, existing requirements engineering approaches and my own experience acquired during working on projects as a business and test analyst. The contribution of the designed methodology is in bringing recommendations, practices and procedures saying how to use Enterprise Architect during the software development process in order to gain the highest possible software quality. The thesis is structured in four sections describing the appropriate theory, analyzed requirement engineering approaches, critical mistakes during this process and the methodology design.
