In clinical applications the quantitative characterization of human kinematics and kinetics can be helpful for clinical doctors in monitoring patients’ recovery status; additionally, the quantitative results may help to strengthen confidence during their rehabilitation. The combination of 3D motion data obtained using an optical motion analysis system and ground reaction forces measured using a...

controller design remains an elusive and challenging problem foruncertain nonlinear dynamics. interval type-2 fuzzy logic systems (it2fls) incomparison with type-1 fuzzy logic systems claim to effectively handle systemuncertainties especially in the presence of disturbances and noises, but lack aformal mechanism to guarantee performance. in contrast, adaptive sliding modecontrol (asmc) provides...

The important and hazardous of the rescue mission in oceans and seas, autonomous vessels now are one of the most appropriate applications among others. Due to safety, reliability, and accessibility of smart, Autonomous and Cooperative vessels today has attracted much attention from the industry. Regard to the complication of the mono vessel for different objects, the multi- agent system was pro...

Understanding the underlying processes and extracting detailed characteristics of rivers is critical has not yet been fully developed. The purpose this study was to examine performance non-linear time series methods on environmental data. Specifically, we performed an analysis water level measurements, extracted from sensors, located specified stations along Nestos River (Greece), with Recurren...

The paper deals with the system dynamics modeling of a stochastic behavior. The starting point is replacing the traditional system dynamics model with a discrete-time stochastic dynamic model in which state variables are measured indirectly, through noisy and incomplete measurements. The state variables and possible unknown parameters in such a model can be systematically estimated from the ava...

different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...

in this study, a novel variable impedance control for a lower-limb rehabilitation robotic system using voltage control strategy is presented. the majority of existing control approaches are based on control torque strategy, which require the knowledge of robot dynamics as well as dynamic of patients. this requires the controller to overcome complex problems such as uncertainties and nonlinearit...

Abstract The purpose of this article is to present a system dynamics (SD) model for studying the ‎interconnections among human being weight, eating habit, exercise, body fat, take-in medication, drugs-uses, and the health problems in general. Due to the fact that all of these factors have direct and indirect impacts on the expenses that insurance company have to pay this author is proposing a ...
