Um processo dirigido a modelos para geração de código
(Universidade Federal de São Carlos, 2013-05-17)
Software development is an activity in constant change over time. Given the complexity and high cost that exists in software construction, there is high demand, especially in the software industries, for methodologies and ...
Reconhecimento de gestos da Língua Brasileira de Sinais através de máquinas de vetores de suporte e campos aleatórios condicionais ocultos
(Universidade Federal de São Carlos, 2013-05-24)
This work investigates the use of Support Vector Machines and Hidden Conditional Random Fields in the recognition of signs from the Brazilian Sign Language (Língua Brasileira de Sinais, Libras). Employing basic concepts ...
Um metamodelo para facilitar a integração de ferramentas de visualização de software e mineração de interesses transversais
(Universidade Federal de São Carlos, 2013-11-22)
A goal of the Object-Oriented Programming is to develop software with better modularization and separation of concerns, although tangling and scattering of some of these concerns cannot be prevented. The Aspect-Oriented ...
Processamento de conhecimento impreciso combinando raciocínio de ontologias fuzzy e sistemas de inferência fuzzy
(Universidade Federal de São Carlos, 2013-12-13)
In Computer Science, ontologies are used for knowledge representation in a number of applications, aiming to structure and handle domain semantics through models shared by humans and computational systems. Although traditional ...
Plataforma computacional híbrida de coprocessamento paralelo distribuído por web services aplicada à radiointerferometria
(Universidade Federal de São Carlos, 2013-08-19)
The requirements imposed by the new applications presents great challenges to the computation. There is not a perfect computer architecture, capable to attend to all the requirements. The parallel and hybrid computer ...
Algoritmo para a extração incremental de sequências relevantes com janelamento e pós-processamento aplicado a dados hidrográficos
(Universidade Federal de São Carlos, 2013-06-07)
The mining of sequential patterns in data from environmental sensors is a challenging task: the data may show noise and may also contain sparse patterns that are difficult to detect. The knowledge extracted from environmental ...
Geração de dados espaciais vagos baseada em modelos exatos
(Universidade Federal de São Carlos, 2013-05-29)
Geographic information systems with the aid of spatial databases store and manage crisp spatial data (or exact spatial data), whose shapes (boundaries) are well defined and have a precise location in space. However, several ...
Análise de escalabilidade de aplicações Hadoop/Mapreduce por meio de simulação
(Universidade Federal de São Carlos, 2013-02-04)
During the last years we have witnessed a significant growing in the amount of data processed in a daily basis by companies, universities, and other institutions. Many use cases report processing of data volumes of petabytes ...
Filtragem de ruído em imagens tomográficas com baixa taxa de contagem utilizando uma abordagem bayesiana contextual
(Universidade Federal de São Carlos, 2013-03-22)
Computed Tomography (CT) images, in many cases, need to be acquired with low photon counting due to low exposure time to the rays of the CT scanner to reduce the radiation doses to the maximum possible (in Medicine, the ...
Super resolução baseada em métodos iterativos de restauração
(Universidade Federal de São Carlos, 2013-06-24)
The resolution enhancement of an image is always desirable, independently of its objective, but mainly if the image has the purpose of visual analysis. The hardware development for increasing the image resolution still has ...
