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 th...

Object shape and camera motion recovery from an image sequence is a crucial issue in computer vision and many methods have been proposed by researchers. Theoretically, these methods are perfect, but they are sensitive to noise, so that in many practical situations, satisfactory results cannot be obtained. To solve this problem, we propose a shape and motion recovery method using a gyro sensor a...

in this research the simulation of an air independent proton exchange membrane fuel cell (pemfc) propulsion system was taken into consideration. the system consists of several parts including pem fuel cell stack, metal hydride and liquid oxygen (lox) tanks, and also pre-heaters of oxygen and hydrogen gases along with other heat exchangers, to ensure proper operation of system. the heat recovery...

For persistent systems to be useful they must provide efficient snapshot and recovery mechanisms. This paper describes the design of the persistence architecture of the Grasshopper operating system which addresses these requirements. It shows how the major components of the architecture interact with one another and how it can be used to provide fast snapshot and recovery times. A novel feature...

Neuroengineering research over the last two decades has demonstrated promising evidence on use of brain-computer interface (BCI) to enhance functional recovery and independence in individuals with motor impairments. By translating brain activity, BCI bypasses impaired neuromotor system, control computers/machines. BCI-controlled robots are designed for assistance aid paralyzed patients as well ...

background: spinal cord injury (sci) is a major clinical condition and research is commonly done to find suitable treatment options. however, there are some degrees of spontaneous recovery after sci and gender is said to be a contributing factor in recovery, but this is controversial. this study was done to compare the effects of sexual dimorphism on spontaneous recovery after spinal cord injur...
