as the world trade is growing, exchange rate acts as a bridge between different economies and its volatility can affect price level, output, exports and imports. the purpose of this study is to investigate the effects of real exchange rate volatility on the export demand for the two products of apple and potato in the nine developing counteries of producing and exporting the two products during...

This paper develops an inventory model for non deteriorating items with time dependent demand rate of production with constant inflation rate. In this model shortages are not allowed, the effect of inflation rate and delay in payments are discussed. In the study mathematical models are also derived under two different cases, i.e. Case-I the credit period is less than or equal to the cycle time ...

Due to the advance of technology, manufacturers’ marketing strategies and quickly changing consumer tastes, numerous products such as fashionable apparel, clothing accessories and consumer electronics are liable to face the problem of short lifespan and obsolescence. Therefore, three related aspects are addressed in this paper. Firstly, we derive a time-dependent demand model for single-period ...

objectives: wheelchairs are the prime mobility aid of persons with spinal cord injuries. manual wheelchair propulsion puts a lot of demand on the cardiopulmonary as well as the skeletal system. the main purpose of the study was to compare the effects of both arm ergometry training and progressive resistance exercise training of upper limbs on resting heart rate and distance covered during wheel...

Abstract: Central banks have long been interested in obtaining precise estimations of money demand given the fact that the evolution of money demand plays a key role over several monetary variables. One implication of currency substitution is that the exchange rate could serve as another determinant of the demand for money. Due to the recent currency crisis in Iran, it would be important to inv...

Latest real-time systems are capable of changing its speed at run time to prolong its battery life and, demand efficient techniques for online decisions making. Available real time feasibility tests have pseudo-polynomial complexity and can not be executed online. This paper proposes that the time complexity of existing techniques could be lowered when task schedulability is analyzed at points,...
