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...

anxiety disorders are a group of psychiatric disorders which can have negative effects on the human life. children and adults can have anxiety disorders and these disorders can lead to secondary problems such as cognitive, perceptual, emotional and behavioral problems. for treatment of anxiety, the practitioners and psychologists can apply psychotherapy approaches such as: cognitive therapy, ge...

the term “system” is defined as «elements standing interaction». this implies that a change in any given element should bring about changes in other elements of the system and thus may be used to identify the boundaries of a system. a system can be a machine, a man, or a community. each of these may be part of a greater system (super system) or include several smaller systems (subsystems). syst...

We construct the analogue of the plactic monoid for the super semistandard Young tableaux over a signed alphabet. This is done by developing a generalization of the Knuth's relations. Moreover we get generalizations of Greene's invariants and Young-Pieri rule. A generalization of the symmetry theorem in the signed case is also obtained. Except for this last result, all the other results are pro...

Super eciency data envelopment analysis(DEA) model can be used in ranking the performanceof ecient decision making units(DMUs). In DEA, non-extreme ecient unitshave a super eciency score one and the existing super eciency DEA models do notprovide a complete ranking about these units. In this paper, we will propose a methodfor ranking the performance of the extreme and non-extreme ecient units.

Lead-acid batteries are widely used in the conventional cars as a main electrical energy storage system to supply power for following start. In this paper, efficacy of lead was evaluated and compared against ultra-capacitors alternative battery designs via simulation-based model complete process. Specifically, several parameters were assessed such weight reliability. The results confirm consist...

Demand is growing for more realistic three-dimensional (3-D) image spaces that can enhance interpersonal communication. Existing 3-D image space systems are mainly based on computer graphics (CG); examples include Cybertown [1] and Interspace [2]. Unfortunately, the image spaces created by existing CG techniques are unnatural and certainly not attractive. There are two problems in creating phot...
