). Relationship between Hemorrhage and Cerebral Blood Flow Hemorrhagic shock (hypotension) is the leading cause of death in both civilian and military injuries. A patient with both a severe head injury and hypotension is four times more likely to die than a patient with a head injury alone ( Manley et al, 2001 ). Despite the brain’s well developed autoregulation ( Strandgaard, Paulson, 1984 ), its vital functions are impaired when the CBF autoregulatory reserve is exhausted by prolonged hypovolemic conditions (hemorrhage). Afferent neural input to the brain seems to be

. High curvature details of process equipment affect the internal flow. Correct information about them allows better models to be developed. True reconstruction of shapes in (b), (c) and (d) is necessary and immensely useful, but EIT reconstruction of these sharp features would smoothen them due to regularization. We have addressed this issue and suggested a solution to improve the image quality, by proposing a new method to locally relax regularization based on the presence of inclusion. This method is named as DeTER – Detection of Target and Edge Refinement. DeTER

polarization that happens mainly in inert metallic materials (stainless steel, gold and platinum) but also in graphite and a few organic materials [ 16 , 18 ]. The electrode polarization is a result of the double layer developed at the electrode-electrolyte interface. In order to solve or attenuate some of the problems mentioned above researchers used symmetrical output current sources. Pliquett et al developed a variation of the Enhanced Howland Current Source [EHCS] based on fully-differential amplifiers to be used with microelectrodes [ 16 ]. Liu et al developed a
