No. of bitstreams: 1 license.txt: 1748 bytes, checksum: 8a4605be74aa9ea9d79846c1fba20a33 (MD5) Previous issue date: 2008 / O crescimento do tamanho, complexidade e demanda por qualidade dos sistemas de software são alguns dos motivos que tem aumentado o interesse na área de arquitetura de software. Consequentemente, processos de arquitetura de software surgiram a fim de auxiliar os arquitetos na construção dessas arquiteturas. Arquitetura Orientada a Serviços (SOA) surgiu como um tipo de arquitetura de software para construir sistemas através da composição de serviços. Assim como o paradigma de orientação a objetos, o paradigma de orientação a serviços tem trazido uma abordagem de projeto distinta que introduz princípios que governam o posicionamento e o projeto dos componentes arquiteturais. Além disso, SOA é um paradigma para organização e utilização de capacidades distribuídas que podem estar sob o controle de diferentes domínios. No contexto empresarial, SOA permite que organizações, que tenham uma infra-estrutura de aplicações fragmentadas sob a administração de diferentes áreas de negócio, possam integrar estas aplicações no nível de serviço. Por um lado, os processos de arquitetura tradicionais não abrangem estes aspectos de SOA. Por outro lado, as abordagens de SOA disponíveis não satisfazem todos os fundamentos da arquitetura de software. Neste sentido, esta dissertação propõe um processo sistemático de arquitetura de software baseado em SOA que compreende os principais fundamentos da arquitetura de software e características inerentes a SOA a fim de guiar os arquitetos na construção de uma descrição arquitetural para SOA. Adicionalmente, um estudo experimental foi definido, planejado, executado e analisado a fim de avaliar o processo proposto

Towards controlling software architecture erosion through runtime conformance monitoring

de Silva, Lakshitha R. January 2014 (has links)
The software architecture of a system is often used to guide and constrain its implementation. While the code structure of an initial implementation is likely to conform to its intended architecture, its dynamic properties cannot always be fully checked until deployment. Routine maintenance and changing requirements can also lead to a deployed system deviating from this architecture over time. Dynamic architecture conformance checking plays an important part in ensuring that software architectures and corresponding implementations stay consistent with one another throughout the software lifecycle. However, runtime conformance checking strategies often force changes to the software, demand tight coupling between the monitoring framework and application, impact performance, require manual intervention, and lack flexibility and extensibility, affecting their viability in practice. This thesis presents a dynamic conformance checking framework called PANDArch framework, which aims to address these issues. PANDArch is designed to be automated, pluggable, non-intrusive, performance-centric, extensible and tolerant of incomplete specifications. The thesis describes the concept and design principles behind PANDArch, and its current implementation, which uses an architecture description language to specify architectures and Java as the target language. The framework is evaluated using three open source software products of different types. The results suggest that dynamic architectural conformance checking with the proposed features may be a viable option in practice.

Implementing software architecture practices in a new environment

Taylor, Paul Leonardo 2009 August 1900 (has links)
During a discussion with the head of the software infrastructure team about the need for software architecture practices at Temple-Inland Company, the manager responded by noting since the company is not a software development company “there are no real benefits to implementing software development practices in the company”. This is an approach taken by many companies whose software development activity is primarily undertaken to support business activities such as the case with manufacturing or financial companies. This paper examines the process of implementing software architectural practices into an organization. The information contained here should be useful to small startup software companies who might assume that it is too costly to incorporate software architectural practices into their current development process. This paper should also benefit large organizations who primarily view software as solutions for short term immediate support and not in terms longer term strategic goals. Software development teams with projects that suffer from cost overruns, scheduling problems and user dissatisfaction should also find this information useful. / text

Implementation of a Modular Software Architecture on a Real-Time Operating System for Generic Control over MRI Compatible Surgical Robots

Gandomi-Bernal, Katie 25 April 2018 (has links)
Software used in medical settings operate in complex and variable environments. Programs need to integrate well not only with their electrical and mechanical components, but also within the socio-technological setting they participate in. In this Master's Thesis, a modular software architecture for controlling surgical robot systems within magnetic resonance scanners is designed and implemented. The C++ program runs on a sbRIO 9651 real-time operating system and an object oriented design is taken. Robot kinematics and controls are put into effect in software and validated. Communication with up to ten daughter cards occurs via SPI and external information is exchanged via OpenIGTLink. A web-based engineering console made with ReactJS is also constructed to provide a visual interface for actuating motor axes and executing robot functionality. Documentation of the code is provided and the program was validated quantitatively with software tests and qualitatively through experimentation in MRI suites.

An Exploration of the Architecture of First Person Shooter Games

Prashar, CHARU 14 January 2014 (has links)
First Person Shooter (FPS) games are one of the most popular game genres and have a history of over 2 decades. While there has been extensive research on such games, the focus has been limited to their analysis at an individual level. In this thesis, we present a comparative analysis of three first person shooter games - Doom, Quake3 and Cube from an architectural point of view. All of these games have come at different times in the history of first person shooter games, and thus possess different and unique features. We describe the process followed in deriving their architecture at various levels of abstraction – the file level, the subsystem level, the library/non-library level and the individual subsystem level for a given part of code. We conclude with a comparative analysis of the similarities and differences in the structure and architecture of the three gaming systems. / Thesis (Master, Computing) -- Queen's University, 2014-01-13 15:26:25.387
