    Object-oriented modeling is spreading in current simulation of wastewater treatments plants through the use of the individual components of the process and its relations to define the underlying dynamic equations. In this paper, we describe the use of the free-software OpenModelica simulation environment for the object-oriented modeling of an activated sludge process under feedback control. The performance of the controlled system was analyzed both under normal conditions and in the presence of disturbances. The object-oriented described approach represents a valuable tool in teaching provides a practical insight in wastewater process control field.Universidad de Málaga.

    Object-oriented modeling and simulation of the closed loop cardiovascular system by using SIMSCAPE

    The modeling of physiological systems via mathematical equations reflects the calculation procedure more than the structure of the real system modeled, with the simulation environment SIMULINK™ being one of the best suited to this strategy. Nevertheless, object-oriented modeling is spreading in current simulation environments through the use of the individual components of the model and its interconnections to define the underlying dynamic equations. In this paper we describe the use of the SIMSCAPE™ simulation environment in the object-oriented modeling of the closed loop cardiovascular system. The described approach represents a valuable tool in the teaching of physiology for graduate medical students

    Interfaz multimodal para un asistente robĂłtico quirĂşrgico: uso de reconocimiento de maniobras quirĂşrgicas

    Resumen: Este trabajo propone una metodología para el reconocimiento de maniobras quirúrgicas en intervenciones de cirugía laparoscópica. El objetivo es la creación de un interfaz entre el cirujano y un asistente robótico quirúrgico de dos brazos para procesos de cirugía mínimamente invasiva. El interfaz propuesto recibe la información sobre el posicionado de las herramientas quirúrgicas del cirujano mediante sensores 3D y el sistema de reconocimiento facilita la maniobra actual que se ha realizado. Por lo tanto, el sistema de reconocimiento de maniobras sobre el que se apoya este interfaz necesita una librería de modelos de maniobras para trabajar. Los modelos elegidos para representar las maniobras quirúrgicas son los Modelos Ocultos de Markov. Para validar la metodología propuesta, se han desarrollado una serie de experimentos in-vitro. Palabras clave: maniobras quirúrgicas, reconocimiento de patrones, interfaz hombre-máquina, asistente robótico quirúrgic
