1. Ambiente computacional para verificaÃÃo de assinaturas invariantes ao tamanho em tempo real / A computacinal enviroment for real time invariant sized signature verification
A great number of studies concerning on-line verification systems have been conducted by researchers in the last years. However, investigations on the influence of different signature sizes on the process of signature formation are little. In fact, this kind of analysis for on-line signature verification system is been made for the first time. In this disser

2. ComposiÃÃo de biometrias para sistemas multimodais de verificaÃÃo de identidade pessol
This work presents contributions for the problem of identity verification thought an architecture that combines face, signature and keystroke dynamics. The first two biometrics were chosen based on the fact that they are already integrated in the society, besides the equipment to capture these modalities are cheap. The third biometrics chosen, keystroke dyna

3. AnÃlise de dados do detector de ondas gravitacionais Allegro: verificaÃÃo de assinaturas de sistemas de mini-buracos negros.
Neste trabalho construÃmos um filtro digital do tipo "matched dois modos" para verificarmos assinaturas de um sinal impulsivo, de radiaÃÃo gravitacional, emitido por um sistema de mini-buracos negros de 0,5 massa solar pouco antes de sua coalescÃncia. Para determinar a forma de onda irradiada pelo sistema, foram utilizadas as equaÃÃes de campo da Teori
