16. Object tracking from compressed video using Kalman Filter and a novel spatiotemporal motion-vector filter.
Video Object Tracking plays a crucial role on several Computer Vision applications, such as Video Surveillance, Intelligent Transportation System (ITS), Human Machine Interface (HMI), Video Indexing and Shopping Behavior Analysis. Nevertheless, the processing power demanded by object tracking techniques still consists in a bottleneck to their wider adoption.

17. Do analÃgico ao Digital: As TransformaÃÃes na ProduÃÃo dos InstantÃneos FotogrÃficos do Cotidiano / From the Analog to the digital: Transformations in the the production of the family snapshots
Os Ãlbuns analÃgicos do cotidiano nos permitem uma memÃria sobre um passado. Dentro deles guardamos imagens de pessoas queridas e de instantes ritualÃsticos. As mÃquinas digitais, por sua vez, possibilitam uma extensa produÃÃo fotogrÃfica que resulta em posturas diferenciadas diante da cÃmera e arquivos digitais extensos. Uma das consequÃncias dess

18. Códigos LDPC quaternários aplicados à técnica de transmissão OFDM / Quaternary LDPC codes applied to OFDM transmission technique
This dissertation addresses the study of error correcting codes based on sparse non-binary matrices. The LDPC (Low Density Parity Check) codes constitute a efficient family of codes generated by sparse parity check matrices and it is considered as one of the classes of codes that presents the best performance in digital communications systems. LDPC codes ove

20. Correlation between 2D:4D, oral squamous cell carcinoma and prostate adenocarcinoma / Correlação entre a proporção 2D:4D, carcinoma espinocelular oral e adenocarcinoma de prostata
The ratio between the index and ring finger, also called 2D:4D, has been attributed by researchers as a possible marker for a plethora of conditions involving human behavior, psychological traits and gender-linked diseases. The difference between these fingers is established in utero, seems not to be affected by puberty and reflects an important factor in

21. O ÍNDICE DE SUSTENTABILIDADE AMBIENTAL DO USO DA ÁGUA (ISA) COMO FERRAMENTA DE CONTRIBUIÇÃO ÀS POLITICAS PÚBLICAS DE DESENVOLVIMENTO E CONSERVAÇÃO NA BACIA DO RIO BACANGA, SÃO LUÍS/ MA. / INDEX FOR ENVIRONMENTAL SUSTAINABILITY OF WATER USE (ISA) AS A TOOL FOR CONTRIBUTION TO THE POLICIES PUBLIC DEVELOPMENT AND CONSERVATION IN BACANGA RIVER BASIN, SÃO LUIS / MA.
A hydrographic basin is a complex environmental system, resulting from the interrelations between the physical-natural and socioeconomic subsystems. Its identity as the unifying of environmental processes and human interference is leading to its adoption as a research unit. It allows from the analysis of the physical-chemical, biological and socioeconomic fa

24. Detecção do complexo QRS em sinais cardiacos utilizando FPGA / QRS complex detection in cardiac signals using FPGA
The electrocardiogram (ECG) is a tool used for diagnosis of diseases related to the heart. This work has the purpose of detecting QRS complex, focusing on the R wave, which represents the ventriclescontraction. It is presented two techniques of processing ECG signals. The first uses Pan &Tompkins algorithm based on digital filtering. The second uses the di
