Using a micro-founded model and a likelihood based inference method, we address three questions in this paper. First, what monetary and scal policy regimes characterized post-war U.S. data? Second, was equilibrium indeterminacy a feature of the economy before Paul Volcker's chairmanship at the Federal Reserve? Third, what were the effects of shifts in monetary and scal policy on the aggregate e...

In the low-temperature multi-effect evaporation (LT-MEE) desalination plant, improving performance of thermal vapor compressor (TVC) could reduce energy loss, and increase gained output ratio (GOR) consequently improve system economy efficiency. Implementing large eddy simulation (LES) as numerical method, a 3-D computational fluid dynamics model TVC is established to simulate flow field under ...

Abstract: The present article reports on the analysis of waste heat and condensate recovery from residential air conditioning (AC) units in different climatic regions Saudi Arabia. Simulation results obtained using a transient dynamic model show that significant amounts water are rejected to environment hot humid climate regions. A multi-generation system for simultaneous cooling pure productio...

In this paper, the crack detection and depth ratio estimation method are presented in beamlikestructures using Elman Networks. For this purpose, by using the frequencies of modes asinput, crack depth ratio of each element was detected as output. Performance of the proposedmethod was evaluated by using three numerical scenarios of crack for fixed-simply supportedbeam consisting of a single crack...

Vocal effort is known to influence the judged distance of speechsound sources. The present research examined whether this influence is due to long-term experience gained prior to the experiment versus short-term experience gained from exposure to speech stimuli earlier in the same experiment. Speech recordings were presented to 192 blindfolded listeners at three levels of vocal output. Even upo...

In an era of discrete tube or transistor op-amp modules, any potential advantage to be gained from fully-differential circuitry was masked by primitive op-amp module performance. Fullydifferential output op-amps were abandoned in favor of single ended op-amps. Fully-differential op-amps were all but forgotten, even when IC technology was developed. The main reason appears to be the simplicity o...

A novel ultra-high compliance, low power, very accurate and high output impedance current output stage (COS) with extremely high output current drive capability is proposed in this paper. The principle of operation of this unique structure is discussed, its most important formulas are derived and its outstanding performance is verified by HSPICE simulation in TSMC 0.18µm CMOS, BSIM3, and Level4...
