Mathematical modelling of the lower urinary tract

The lower urinary tract is one of the most complex biological systems of the human body as it involved hydrodynamic properties of urine and muscle. Moreover, its complexity is increased to be managed by voluntary and involuntary neural systems. In this paper, a mathematical model of the lower urinary tract it is proposed as a preliminary study to better understand its functioning. Furthermore, another goal of that mathematical model proposal is to provide a basis for developing artificial control systems. Lower urinary tract is comprised of two interacting systems: the mechanical system and the neural regulator. The latter has the function of controlling the mechanical system to perform the voiding process. The results of the tests reproduce experimental data with high degree of accuracy. Also, these results indicate that simulations not only with healthy patients but also of patients with dysfunctions with neurological etiology present urodynamic curves very similar to those obtained in clinical studies.

Piloto automático: Sistema de navegação autónoma

Desde o início do crescente interesse na área de robótica que a navegação autónoma se apresenta como um problema de complexa resolução que, por isso, desperta vasto interesse no meio científico. Além disso, as capacidades da navegação autónoma aliadas à robótica permitem o desenvolvimento de variadas aplicações. O objectivo da navegação autónoma é conferir, a um dispositivo motor, capacidade de decisão relativa à locomoção. Para o efeito, utilizam-se sensores, como os sensores IMU, o receptor GPS e os encoders, para fornecer os dados essenciais à navegação. A dificuldade encontra-se no correcto processamento destes sinais uma vez que são susceptíveis a fontes de ruído. Este trabalho apresenta um sistema de navegação autónomo aplicado ao controlo de um robot. Para tal, desenvolveu-se uma aplicação que alberga todo o sistema de localização, navegação e controlo, acrescido de uma interface gráfica, que permite a visualização em mapa da movimentação autónoma do robot. Recorre-se ao Filtro de Kalman como método probabilístico de estimação de posição, em que os sinais dos vários sensores são conjugados e filtrados. Foram realizados vários testes de modo a avaliar a capacidade do robot atingir os pontos traçados e a sua autonomia no seguimento da trajectória pretendida.
