1. A Novel In Silico Monte Carlo Approach to Optimize a PSD Estimation Problem. Generation of Data Fusion Experiment Rules
ABSTRACT This article analyzes the performance of combining information from Scanning Electron Microscopy (SEM) micrographs with Static Light Scattering (SLS) measurements for retrieving the so-called Particle Size Distribution (PSD) in terms of experimental features. The corresponding data fusion is implemented using a novel Monte Carlo-based method consist

2. Qualidade dos sistemas de informações sobre nascidos vivos e sobre mortalidade no Rio Grande do Sul, Brasil, 2000 a 2014
Resumo O estudo avalia a qualidade do SIM e do SINASC nos aspectos cobertura, incompletitude e consistência, bem como a contribuição do “linkage” para a recuperação de dados. Foram analisados nascimentos e óbitos de menores de um ano ocorridos no Rio Grande do Sul entre 2000 e 2014. Os registros foram pareados por “linkage” determinístico atra

3. Content Based Geographic Image Retrieval using Local Vector Pattern
ABSTRACT Large image archives formed by satellite remote sensing missions are getting an increasing valuable source of information in Geographic Information Systems (GIS). The need for retrieving a required image from a huge image database is increasing significantly for the purpose of analyzing resources in GIS. Content Based Geographic Image Retrieval (CBG

4. La representación de documentos y autoridades archivísticas: una mirada desde la perspectiva de la normalización
ABSTRACT Nowadays, the archival science is going through a big changes in its conception as science. As a result, the discipline has gone from the inactivity in the normalization of their tasks to the regulatory action of most its processes. In the late twentieth century, institutions such as the International Council on Archives and prestigious associations

5. Exploiting contextual information for image re-ranking and rank aggregation in image retrieval tasks = : Explorando informações contextuais para reclassificação de imagens e agregação de listas em tarefas de recuperação de imagens / Explorando informações contextuais para reclassificação de imagens e agregação de listas em tarefas de recuperação de imagens
Content-Based Image Retrieval (CBIR) systems aims at meeting the user needs expressed in query specifications. Given a query pattern (e.g., query image) as input, a CBIR system retrieves the most similar images in a collection by taking into account image visual properties. Since users are interested in the images placed at the first positions of the returne

6. Criação e performance musical no contexto dos instrumentos musicais digitais / Music creation and performance in the context of digital musical instruments
This work presents a study about the computer as an instrument for musical performance. Based on this study we developed processes of music creation using the algorithmic representation and the computer code. The two main technical resources we applied in our works were: a sound synthesis method based on the generation of waveforms by non-linear equations; a

7. Recuperação de vídeos comprimidos por conteúdo / Content-based retrieval of compressed videos
Recent advances in the technology have enabled the increase of the availability of video data, creating large digital video collections. This has spurred great interest in systems that are able to manage those data in a efficient way. Making efficient use of video information requires the development of powerful tools to extract high-level semantics from low

8. Auxílio na prevenção de doenças crônicas por meio de mapeamento e relacionamento conceitual de informações em biomedicina / Support in the Prevention of Chronic Diseases by means of Mapping and Conceptual Relationship of Biomedical Information
Genomic medicine has suggested that the exposure to risk factors since conception may influence gene expression and consequently induce the development of chronic diseases in adulthood. Scientific papers bringing up these discoveries indicate that epigenetics must be exploited to prevent diseases of high prevalence, such as cardiovascular diseases, diabetes

10. Busca multimodal para apoio à pesquisa em biodiversidade / Multimodal search to support research on biodiversity
Research on Computing applied to biodiversity present several challenges, ranging from the massive volumes of highly heterogeneous data to the variety in user profiles. This kind of scenario requires versatile data retrieval and management tools. Available tools are still limited. Most often, they only consider textual data and do not take advantage of the m

11. A influência dos parâmetros de Análise por Semântica Latente aplicada a localização de defeitos de software
During its life cycle, software systems must pass through continuous change to have bugs fixed and get a reasonable conformance between user requirements and implemented software functions. The necessary effort to execute such changes that occur in the software maintenance phase is considerable and is influenced by the developer software comprehension level.
