We translate in semi-group theory our proof of Varadhan estimates for subelliptic Laplacians which was using the theory of large deviations of Wentzel-Freidlin and the Malliavin Calculus of Bismut type. Key–Words: Large deviations. Subelliptic estimates.

Was the Great Depression preceded by a period of excessive monetary expansion? The answer to this question would provide support for either the Monetarist view of the Great Depression as it currently stands or a view that incorporates the Austrian analysis, but not both. In this paper, we question the original calculations by Friedman and Schwartz (1963), which have since become the orthodox po...

The positive response of prices to an increase in interest rates or contractionary monetary policy has been documented by several empirical studies.2 According to monetarist as well as IS-LM models, an increase in interest rates or contractionary monetary policy reduces aggregate demand leading to a decrease in the price level. As a result, this positive response of prices to positive interest ...

After extreme events such as floods, thunderstorms, blizzards and hurricanes there will be devastating effects in the distribution networks which may cause a partial or complete blackout. Then, the major concern for the system operators is to restore the maximum critical loads as soon as possible by available generation units.  In order to solve this problem, this paper provides a restoration s...

one of the difficulties of data envelopment analysis(dea) is the problem of deciency discriminationamong efficient decision making units(dmus) and hence, yielding large number of dmus as efficientones. the main purpose of this paper is to overcome this inability. one of the methods for rankingefficient dmus is minimizing the coefficient of variation (cv) for inputs-outputs weights. in this pap...

in the present study, the potential of a bacterial consortium of enterobacter cloacae and pseudomonas sp. (ercppi-2) for microbial enhanced oil recovery was investigated. various mechanisms of enhanced oil recovery (eor) as a result of using ercppi-2 and its metabolic products were studied in detail. the obtained results showed that under simulated reservoir conditions, interfacial tension redu...
