25. Processamento de consultas em redes de sensores sem fio : uma abordagem de detecção de novidades para o controle da qualidade dos serviços de consultas / Processamento de Consultas em Redes de Sensores sem Fio: Uma Abordagem de Detecção de Novidades para o Controle da Qualidade dos Serviços das Consultas
Wireless Sensor Networks (WSNs) are communication networks composed of geographically distributed devices (sensor nodes) which can be used to monitor a variety of physical phenomena in real time. Due to the nature of these devices, WSNs have computational restrictions in terms of data processing and storage, and they are usually prone to failures. The main c

29. Retroanálise probabilista aplicada à análise dinâmica da cravação de estacas. / Probabilistic back-analysis applied to dynamic loading test for pile driving.
An dynamic loading test can be performed in concrete piles, bored piles, drilled shafts, auger cast-in-place (continuous flight auger) piles. Such essay bases on the Theory of the Propagation of Wave in piles with the aim of evaluate the capacity of static load mobilized from the dynamic event. The analysis of the test is made by a PC program (p.e. CAPWAP or
