    This paper considers part of the problem of how to provide unsupported standing for paraplegics by feedback control. In this work our overall objective is to stabilize the subject by stimulation only of his ankle joints while the other joints are braced. We investigate the problem of ankle joint moment control. The ankle plantarflexion muscles are first identified with pseudorandom binary sequence... View full abstract»

    In biology and mathematics compartmental systems are frequently used. System identification of systems based on physical laws often involves parameter estimation. Before parameter estimation can take place, we have to examine whether the parameters are structurally identifiable. In this paper tests for the structural identifiability of linear compartmental systems are proposed. The method is based... View full abstract»

    This paper investigates the use of adaptive neural network techniques for modeling and automatic control of mean arterial pressure through the intravenous infusion of sodium nitroprusside. An indirect model reference-based adaptive nonlinear control scheme with neural networks approximating the unknown nonlinearities, is developed. In this formulation nonlinear estimators are used to adaptively ap... View full abstract»

    To clarify the mechanisms maintaining chronic atrial fibrillation (CAF), a method for system identification of activation patterns of the atria during sinus rhythm (SR), artificial atrial pacing and atrial fibrillation, was developed. Data were obtained as repeated recordings of 8 sec in duration, each of 56 atrial bipolar electrograms, simultaneously acquired during open-heart surgery at multiple... View full abstract»

    The paper aims to use the knowledge about how the visual system organizes the components of oculomotor system to propose a new tracking paradigm. The tracking system is assumed to be described by linear time-invariant discrete-time state-space equations. The approach described, motivated by the behavior of the visual system, is to switch off the smooth controller whenever a violation occurs and de... View full abstract»

    An extended Kalman filter estimator for the identification of systemic circulation model parameters during cardiac ejection and cardiac filling is described. The estimator has been developed for use in the control of a cardiac ventricular assist device. A lumped element circuit with a time-varying capacitor was used to represent the systemic circulation and the left ventricle. Since the haemodynam... View full abstract»

    We illustrate some novel procedures of using Sinc methods to compute solutions to three types of medical problems. The first of these is a novel way to solve optimal control problems, the second is an original way to reconstruct images for X-ray tomography, and the third is a novel way to do ultrasonic tomography inversion. Each of these procedures uses Sinc convolution, which is a novel computati... View full abstract»

    The varicella-zoster virus (VZV) is responsible for the infectious diseases varicella and herpes zoster, more commonly known as chickenpox and shingles. The United States Food and Drug Administration recently approved a VZV vaccine for use in children to prevent chickenpox. The VZV vaccine was tested in Japan, Korea, and the United States, and these extensive experimental investigations led to fin... View full abstract»
