Cardiovascular rehabilitation soon after stroke using feedback-controlled robotics-assisted treadmill exercise: study protocol of a randomised controlled pilot trial

BACKGROUND After experiencing a stroke, most individuals also suffer from cardiac disease, are immobile and thus have low endurance for exercise. Aerobic capacity is seriously reduced in these individuals and does not reach reasonable levels after conventional rehabilitation programmes. Cardiovascular exercise is beneficial for improvement of aerobic capacity in mild to moderate stroke. However...

The Effect of Aerobic Continuous Training on Myonectin, Insulin Resistance and Liver Enzymes in Rats with Nonalcoholic Fatty Liver Disease

Background. Non-alcoholic fatty liver disease, is the most common reason of liver disorders that can be controlled by dieting and regular physical activity.  Objectives. The aim of this study was to investigate the effect of aerobic continuous training on serum levels of myonectin, insulin resistance and liver enzymes in rats with non-alcoholic fatty liver disease. Methods. Thirty-four male W...

Adaptive fuzzy pole placement for stabilization of non-linear systems

A new approach for pole placement of nonlinear systems using state feedback and fuzzy system is proposed. We use a new online fuzzy training method to identify and to obtain a fuzzy model for the unknown nonlinear system using only the system input and output. Then, we linearized this identified model at each sampling time to have an approximate linear time varying system. In order to stabilize...

An Adaptive Cascade Structure for the Estimation and Control of Perfusion Animal Cell Cultures

This paper presents an effective and robust structure for the estimation and control of perfusion cell cultures, in which the cells and glucose concentrations are simultaneously controlled by manipulating the dilution and bleed rates. Firstly, a partially linearizing feedback controller is designed to ensure an approximately linear decoupled dynamics between the controlled outputs and the manip...
