Stable matching mechanisms are used to clear many two-sided markets. In practice, these mechanisms leave many agents on both sides unmatched. What factors determine the number of unmatched agents, and the quality of matches that do form? This paper answers these questions, with a particular focus on how match outcomes depend on correlations in agent preferences. I consider three canonical prefe...

in this paper, monopolistic behavior of opec, as the largest and most stable international organization between jan. 1973 to sep. 2008, is studied. for this purpose, fundamentals of game theory is used as a basis to come-up with a criterion to make a distinction between two market structures based on mutual dependency of institutions. then using such criterion, a regressive model based on expla...

To explore the possibility of using graphene based biosensor, adsorption of hydrogen peroxide on graphene has been investigated using density functional theory. The electronic properties of defect free and defective graphene in the presence of different number of hydrogen peroxide have been studied. The graphene with the most stable configuration defect named as SW defect is considered. The hig...

This paper investigates the dynamic behavior of Gas Metal Arc Welding (GMAW) process for two types of power supplies –inverter and rectifier- for short circuit transfer mode. The large ripples on the rectifier power source are able to perturb the metal transfer mode. In this experimental work some operating points in the short circuit mode have been selected using an automatic pipeline welding ...

In Hard Disk Drives (HDD), it is necessary to decrease the Flying Height (FH) between the head and the disk (currently, FH is around 3-5 nm) so as to increase recording densities. Retaining the solid lubricant has become a difficult proposition owing to intermittent contact between the surfaces. ZTMD and Z are used as solid lubricant to lubricate these interfaces. In this paper, the behavior of...

it is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical and physical functions of clouds. hence, aerosol field sampling was conducted in the skies offshore from malibu beach and santa barbara, california, u.s.a. on 16 and 18 july 200...

In environments with “diffuse” uncertainty, we study bidding behavior in auctions and double auctions. Our dynamics has a strong component of inertia but with a small probability, bids are modified in the direction of ex-post regrets. We apply stochastic stability to identify essentially a unique bid that will be used by each type in the long run. In the first-price auction, bidding half of one...

This paper addresses the analysis of combinational cycles in synchronous, sequential circuits. A circuit that has a com-binational cycle does not necessarily have unstable output behavior: the cycle may be \false" for all reachable states and possible input sequences, or the unstable behavior on the cycle may not aaect the outputs. We provide a procedure to determine whether a circuit produces ...
