A fully discrete approximation of the semi-linear stochastic wave equation driven by multiplicative noise is presented. A standard linear finite element approximation is used in space and a stochastic trigonometric method for the temporal approximation. This explicit time integrator allows for mean-square error bounds independent of the space discretisation and thus do not suffer from a step si...

One form of the environmentally friendly power plant is Micro Hydro Power (MHP). An area in East Java that uses MHP as a source Seloliman Village Mojokerto. Although this village has resources to produce electricity independently, not all residents are willing use energy for various reasons. This study aims formulate consumption patterns users rural areas based on socio-economic characteristics...

Present study investigates the effect of soaring residential electricity price on the welfare of rural individuals in Guilan Province by Almost Ideal Demand System (AIDS) in which the elasticity’s and welfare variations were calculated by Compensation Variations (CV) and Equivalent Variations (EV) for the time period of 1991-2012. It was shown that the absolute value of income and price elastic...

The objective of this study has been to develop a typical specification of the Almost Ideal Demand System (AIDS) for Iran’s composition of imports including capital, intermediate and consumer goods. Accordingly, we first test the hypotheses that import demand is homothetic, homogeneous, symmetric, and depends on domestic prices. Then, we estimate the long-run elasticities of the composition o...

The aim of this paper is to generalize the‎ ‎notion of almost valuation domains to arbitrary commutative‎ ‎rings‎. ‎Also‎, ‎we consider relations between almost valuation rings ‎and pseudo-almost valuation rings‎. ‎We prove that the class of‎ ‎almost valuation rings is properly contained in the class of‎ ‎pseudo-almost valuation rings‎. ‎Among the properties of almost‎ ‎valuation rings‎, ‎we sh...

We consider the complexity of decision making with regards to predatory pricing in multimarket oligopoly models. Specifically, we present multimarket extensions of the classical single-market models of Bertrand, Cournot and Stackelberg, and introduce the War Chest Minimization Problem. This is the natural problem of deciding whether a firm has a sufficiently large war chest to win a price war. ...
