Esta monografia apresenta uma estrutura de aprendizagem profunda para a caracterização do fundo marinho, combinando a física de campos acústicos vectoriais com redes neuronais. Introduz parâmetros de Stokes obtidos por hidrofones vectoriais como características robustas para a inversão geoacústica e desenvolve redes especializadas (BP, MTL-TCN, U-Net + ATT-BP) para estimar parâmetros de sedimentos e extrair curvas de dispersão. Validado no Mar Amarelo, o método consegue uma precisão comparável à dos testemunhos de sondagem em poucos minutos, superando significativamente as técnicas tradicionais em velocidade e robustez. O trabalho destaca a sinergia entre os princípios físicos e a aprendizagem baseada em dados, oferecendo uma solução escalável para o mapeamento do fundo marinho em tempo real e impulsionando a deteção oceânica autónoma.

     We introduce the theory of chemical reaction networks and their relation to stochastic Petri nets — important ways of modeling population biology and many other fields. We explain how techniques from quantum mechanics can be used to study these models. This relies on a profound and still mysterious analogy between quantum theory and probability theory, which we explore in deta...

    Once in a lifetime we might witness a scientific event so rare and revolutionary that it changes our lives forever. Imagine awakening on the day in history when we learned that the Earth is round, not flat; or awakening on the day we learned that the planets orbit the Sun, not the Earth. Now, imagine awakening tomorrow to learn that Einstein's theory of relativity is wrong!...
