EEcient abstractions for Location management is a key consideration in wireless networks that support Universal Personal Communications. Location management involves a tracking component that maintains dynamic data on the location of mobile stations through a distributed database, and a search component that prescribes the manner in which the wireless network is to be paged so as to determine t...

in this paper, the effects of roll center height of mcpherson suspension mechanism on dynamic behaviour of a vehicle is studied first and then the optimum location of roll center of this suspension system is determined for a conceptual class a vehicle. adams/car software was used for analysis of vehicle dynamic behaviour in different positions of suspension roll center, then optimization proces...

the present study sustainable management of guilan saravan sylvan park was planned. the used method in the form of decision support model in three10-year period was studied for parks of various states and with considering the economic, ecological and social criteria during the years 2008 to 2038. by using hierarchical fuzzy analysis method, the reaching to an optimal level of economic, ecologic...

This paper outlines a dynamic model of firm location choice, in an environment which includes both agglomeration effects and stochastic productivity shocks. The model follows closely the methods of Hopenhayn (1992) and his treatment of firm level entry and exit decisions. However, this model adds the complexity of a second location, as well as the existence of spillover effects, or agglomeratio...

Dynamic lot sizing problem is one of the significant problem in industrial units and it has been considered by  many researchers. Considering the quantity discount in  purchasing cost is one of the important and practical assumptions in the field of inventory control models and it has been less focused in terms of stochastic version of dynamic lot sizing problem. In  this paper, stochastic dyn...
