High Speed Clock and Data Recovery Techniques Behrooz Abiri Master of Applied Science Graduate Department of Electrical and Computer Engineering University of Toronto 2011 This thesis presents two contributions in the area of high speed clock and data recovery systems. These contributions are focused on the fast phase recovery and adaptive equalization techniques. The first contribution of this...
objective: to assess the effect of combination of pulsed electromagnetic fields (pemf) with predatory stress on transected sciatic nerve regeneration in rats. methods: in sham- operated group (sog) the nerve was manipulated and left intact. the 10-mm rat sciatic nerve gap was created in rats. in transected group (transected) nerve stumps were sutured to adjacent muscle and in vein graft group ...
background: we aimed to research the value of extended nursing for cerebral stroke patients within a suitable recovery empty period. methods: seventy-two cerebral stroke patients were randomized to a control group or treatment group at the recovery period at xuzhou recovery hospital, china in 2016. a recovery guidance exercise was applied to the control group for a set time, while a recovery gu...
oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (hl1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (hl2) were synthesized and characterized by conventional spectroscopic methods. suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extraction-separation of copper from its mixture with normally associated meta...
the micro milling operation is one of the manufacturing processes, which can produce 3d parts in the range of less than a millimetre. miniaturization of components results in increasing the ratio of surface area to volume of components, which in turn increases the role of surface on the component performance. therefore, anticipating the relationship between micro milling parameters and surface ...
zno and zno: mn nanocrystals were synthesized via reverse micelle method. the structural properties of nanocrystals were investigated by xrd. the xrd results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...
conceptual design of a waste heat recovery cycle is carried out in attempt to enhance the thermal efficiency of a steam power plant. in the recovery system, super-critical an co2 is employed as the working fluid operating in a brayton cycle. low grade heat rejected by the flue gases through the stack is used as the primary heat source, while a secondary heat exchanger utilizes the hot gases lea...
recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. at the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver int...
in this paper, a simplified formulation for compositional reservoir simulator is presented. these types of simulators are used when inter-phase mass transfer depends on phase composition as well as pressure. the procedure for solving compositional model equations is completely described. for equilibrium calculation, property estimation peng robinson equation of state is used. this equation was ...
introduction: spinal cord injury (sci) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. after severe spinal cord injury, astrocytes of the central nervous system (cns) become reactive astrocytes, and play the main role of glial scar formation. the scar is a major obstacle t...
