Impedance tube method is widely used to measure acoustic properties of materials. Although this yields reliable for soft textured materials, uncertainty levels measured hard including biocomposites, can be quite large, mainly due uncertain mounting conditions. Here, the effects conditions on biocomposites in an impedance are investigated. First, nominally identical biocomposite samples with a d...

measurement of the stroke volume and its changes over time can be very helpful for diagnosis of dysfunctions in the blood circulatory system and monitoring their treatments. impedance cardiography (icg) is a simple method of measuring the stroke volume based on changes in the instantaneous mean impedanceof the thorax. this method has received much attention in the last two decades because it is...

The appearance of uncertainties and disturbances often effects the characteristics either linear or nonlinear systems. Plus, stabilization process may be deteriorated thus incurring a catastrophic effect to system performance. As such, this manuscript addresses concept matching condition for systems that are suffering from miss-match exogeneous disturbances. perturbation towards at hand is assu...

The aim of the present study was to investigate The effect of HMB-FA supplementation on the muscle damage markers after soccer matches. 24 male soccer players (age: 23±3 years, BMI: 22.8±2 kg/m2) were voluntarily selected as the statistical sample of this study and were divided into two Suppplement and Placebo groups (n=12). In this study, subjects participated in a weekly soccer microcycle wit...

studies show that any complications including hemorrhage, lack of blood supply, lack of oxygen supply, and death of cells in a tissue, will have a clear effect on electrical properties of that tissue. thus, by measuring impedance of a set of tissues, potential problems of the damaged tissue may be found. since electrical impedance is closely related to the measuring frequency, obviously, every ...
