Alireza Esmaieli Hassan Hajabdollahi,

A regenerative organic Rankine cycle (RORC) is modeled and optimized for the use of waste heat recovery from a prime mover (PM). Three PMs including, a diesel engine, a gas engine, and a microturbine are selected in this study. Four refrigerants including isobutane, R123, R134a, and R245fa are selected. The nominal capacity of the PM, PM operating partial load, turbine inlet pressure, condenser...

Presently, orthogonal frequency division multiplexing (OFDM) as a multicarrier transmission system is widely used. Along with its advantages it has many disadvantages. One of its major drawback is high peak to average power ratio (PAPR). As with high PAPR the spectral efficiency of the high power amplifiers degrades. So it becomes necessary to maintain the efficiency of a wireless system to red...

The data show that the filipin complex in water has a characteristic fluorescence spectrum with a broad emission maxima at 497nm. Addition of cholesterol to the aqueous solution decreases the absorbance, the corrected fluorescence, and the partial quantum efficiency. The reduction in partial quantum efficiency, which is independent of the concentration of filipin, is definitive evidence that th...

Alkali-Antimonide growth was examined at the Center of Functional Nanomaterials (CFN) at Brookhaven National Laboratory (BNL). The materials were grown in a UHV chamber and analyzed by means of core-level xray electron spectroscopy (XPS) and UHV-atomic-force microscopy (UHV-AFM). We were able to grow CsK2Sb cathodes with an average quantum efficiency around 12.5 % under good vacuum conditions.T...

We derive a general analytic expression for the coupling efficiency when a partially coherent, partially polarized beam is coupled into a multimode optical fiber. We adopt the Gaussian-Schell model for incident electromagnetic beams and use our general result to discuss the effects of the partial coherence and partial polarization on the coupling efficiency of an optical beam focused onto a ste...

We first introduce a new notion of the partial and generalized cone subconvexlike set-valued map and give an equivalent characterization of the partial and generalized cone subconvexlike set-valued map in linear spaces. Secondly, a generalized alternative theorem of the partial and generalized cone subconvexlike set-valued map was presented. Finally, Kuhn-Tucker conditions of set-valued optimiz...
