on one hand, oil is the greatest energy resource in the world and, on the other hand, because of the role of oil revenue in the economic of oil producer countries, such as iran,it is vital for these countries. so it is necessary to recognize different affective parameters on oil market for these countries. in this research, we try to forecast oil price as an important variable in world wide oil...

Abstract The minimum uncut chip thickness (MUCT) is an important phenomenon observed both in orthogonal and oblique cutting. Rounding the cutting edge influences initiation of process formation. In a previous study, authors presented theoretical analysis experimental validation on effect inclination angle ? s range 0° to 60° h min radial-free turning C45 steel. current work investigated MUCT st...

Abstract The frictional cooperation of materials with different hardnesses occurs in machine elements one the following two variants: simple or reversed friction pairs. For a sliding pair, materials' deformation area (contact area) does not move over surface polymeric element during their interaction. In case pairs, contact changes its position as it moves polymer element. Tribological tests se...

A method of ultrasonic surface plastic deformation is widely used to change the properties layers metal products. Under influence this type treatment, structure material changes, microhardness increases, roughness decreases, internal tensile stresses are removed, and compressive created. Now many types have been developed, which differ in degree impact on material. The object paper study microg...

This paper employs a neural network (NN) to study the nonlinear predictability of exchange rates for four currencies at the 1-, 6and 12-month forecast horizons. We find that our neural network model with market fundamentals cannot beat the random walk (RW) in out-of-sample forecast accuracy, although it occasionally shows a limited market-timing ability. The neural network model without monetar...

Dans les années 1940-1970, Alexandrov et l’“École de Leningrad” ont développé une théorie très riche des surfaces singulières. Il s’agit de surfaces topologiques, munie d’une métrique intrinsèque pour laquelle on peut définir une notion de courbure, qui est une mesure de Radon. Cette classe de surfaces a de bonnes propriétés de convergence et elle est remarquablement stable par rapport à divers...
