Different trunked Private Mobile Radio (PMR) systems have been designed over the last several decades, all of which have symmetric downlink and uplink channel capacities. Due to this symmetry, these systems may not be spectrally efficient in case of

The point spread function (PSF) is the most widely used tool for quantifying the spatial resolution of imaging systems. However, prerequisites for the proper use of this tool are linearity and space invariance. Because EIT is non-linear it is only po

In this paper, we propose a fast algorithm for the reconstruction of the conductivity perturbation delta sigma about a known conductivity variation sigma omicron. The method is based on the minimization of a quadratic functional subject to linear con

In order to circumvent the electrode position determination problem in static electrical impedance tomography, it is possible to insert the object to be imaged into a water-filled cylinder on which the electrodes are at fixed and known positions. It

In electrical impedance tomogmphy, two-dimensional (2D) finite element solutions are used in the imaging algorithms. It is assumed that a major part of the current flowing through the object is restricted to the measurement plane (i.e. the plane dete

Huge amount of data recorded during exercise electrocardiography may be stored for further analysis or be transferred to a remote physician through telephone lines. Due to channel limitations, data must be compressed prior to the transfer, In this st

It is generally accepted that HRV (heart rate variability) LF component frequency is related to the baroreflex control mechanism. In this study, HRV LF component and HRT (heart rate turbulence) spectrums are compared, and it is found that both have s
