    A mathematical model of skeletal muscle activation during small or isometric movements is discussed with the following attributes. A direct relationship between the stimulus rate and the active state is established. A piecewise linear relation between the length of the contractile element and the isometric force is considered. Hill's characteristic equation is maintained for determining the actual... View full abstract»

    A mathematical model of gas transport in the airways of the human lung with numerical solution of the corresponding differential. equation is presented. The model takes into account, along with the summed cross section of. the Weibel lung model, both convection and longitudinal dispersion of helium and sulphur hexafluoride in air. Simulation was performed using two dispersion coefficients correspo... View full abstract»

    A laser interferometer has been developed which was used to measure vibratory displacements of the cricket's posterior tympanic membrane with a sensitivity of less than 0.1 A. A special feature is the incorporation of an optical fiber in two of its arms, which makes possible its use in hard-to-access areas. Another feature is its Fizeau configuration, which enables one to eliminate much undesirabl... View full abstract»

    Changes in the resistance and tip potential of open-tip glass microelectrodes as function of the polarity and intensity of an injected current are presented and analyzed. These experimental results are explained on the basis of a quantitative diffusion model which includes an electroosmotic effect through the microtip. This study also results in a practical method to improve microelectrode selecti... View full abstract»

    A method for the straightforward estimation of the param eters in lumped continuous linear models of respiratory mechanics is presented in this paper. First, a discrete-time model is obtained from the samples of input-output data and then transformed into a conuous-time model. View full abstract»

    Performance characteristics of three implantable triaxial field probes for measuring intensities of the internal electric fields in biological tissues at radio frequencies are given. The sensitivity in air between 100 MHz and 3 GHz, and in phantom materials at 350, 915, and 2450 MHz, are given for the Holaday model IME-01, EIT model 979, and Narda model 2608 implantable probes, as well as their no...

    Thermal conductivity, specific heat, density, and thermal diffusivity were determined for standard RF and microwave phantom materials. Thermal conductivity data for seven phantom materials of varying aluminum content were analyzed using mixture theories. With the thermal diffusivity values obtained, worst case errors in SAR determination due to thermal conduction for adipose-muscle planar phantoms... View full abstract»
