    Este trabajo tiene cómo objetivo desarrollar una aplicación móvil para ayudar en el diagnóstico diferencial entre pacientes con Parkinson y pacientes con Temblor Esencial Estos son los síndromes de temblor más comunes en todo el mundo Para lograr esto, se desarrollaron modelos de Machine Learning a partir de diferentes características cinemáticas de las señales de la velocidad angular del temblor de mano de sujetos sanos y pacientes con temblor usando el giroscopio de un teléfono móvil Los modelos desarrollados se implementaron en un servidor web y una aplicación móvil para hacer el registro, el procesamiento y la clasificación de las señales de velocidad angular El modelo implementado para diferenciar sujetos con temblor patológico de sujetos con temblor fisiológicos mostró un 97 06 de sensibilidad y un 100 de especificidad Por otro lado, el modelo implementado para diferenciar entre los dos síndromes de temblor mostró un 95 00 de sensibilidad y un 100 de especificidad Con esto, se presume que esta aplicación le servirá de apoyo a los médicos especialistas que tratan patologías y trastornos del movimiento a realizar diagnósticos tempranosPostprint (published version

    Torque control strategy for an axial flux switched reluctance machine

    This paper reflects the work done to design a torque control strategy for an axial flux switched reluctance machine. The general electrical model is first presented but as the switched reluctance machine behaves nonlinearly1 a (three-dimensional) finite element method characterization is performed, so the nonlinearity may be considered. Once the machine is characterized in FEM a Simulink model is developed where a torque control strategy is proposed. Then, both the machine and the control are experimentally tested. The control setting, and the obtained real performance results are also presented in this document. Finally, the most outstanding conclusions about the control strategy are captured. Main difficulties encountered during the implementation of the control strategy are also collected

Werner y revisamos los pliegos correspondientes conservados en el herbario del Instituto Botánico de Barcelona (BC).All species of the lichen family Lichinaceae reported from northern Africa in Prof. Werner's works are compiled. A revision on the material collected corresponding to these species and actually included in BC herbarium is made

    Introducing probabilistic celular automata. A versatile extension of Game of Live

    Get PDF
    The "Game of life" model was created in 1970 by the mathematician Jonh Horton Conway using cellular automata. Since then, di erent extensions of these cellular automata have been used in many applications, such as car traffic control or baggage traffic in an airport. These extensions introduce ideas not only from cellular automata models but also from neural networks theory. In this work, we introduce probabilistic cellular automata which include non-deterministic rules for transitions between successive generations of the automaton together with probabilistic decisions about life and death of the cells in next generation of the automaton. This way, more realistic situations can be modeled and the obtained results are also non-deterministic. As an example of use, an implementation of this probabilistic cellular automaton has been developed using it for simulating tissues evolution. The authors are specially interested in simulations of cancerous tissues.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tech
