If the computational demands of an interactive graphics rendering application cannot be met by a single commodity Graphics Processing Unit (GPU), multiple graphics accelerators may be utilised on multi-GPU based systems such as SLI [1] or Crossfire [2] or by a cluster of PCs in conjunction with a software infrastructure. Typically these PC cluster solutions allow the application programmer to u...

We study valuation of swing options on commodity markets when the commodity prices are driven by multiple factors. The factors are modeled as diffusion processes driven by a multidimensional Lévy process. We set up a valuation model in terms of a dynamic programming problem where the option can be exercised continuously in time. Here, the number of swing rights is given by a total volume constr...

abstract in this paper an attempt is made to determine the most suitable agricultural commodities to be adopted for establishing a futures market in iran. two different approaches are adopted: the first involves identifying factors that contribute significantly to the success or failure of existing agricultural commodities futures contracts in established futures markets. the second involves si...

Nonorthogonal multiple access (NOMA) significantly improves the connectivity opportunities and enhances spectrum efficiency (SE) in fifth generation beyond (B5G) wireless communications. Meanwhile, emerging B5G services demand for higher SE NOMA-based However, traditional ground-to-ground (G2G) communications are hard to satisfy these demands, especially cellular uplinks. To solve challenges, t...

In today’s competitive transportation systems, passengers search to find traveling agencies that are able to serve them efficiently considering both traveling time and transportation costs. In this paper, we present a new model for the traveling salesman problem with multiple transporters (TSPMT). In the proposed model, which is more applicable than the traditional versions, each city has diffe...

Determination of shipment quantity and distribution problem is an important subject in today’s business. This paper describes the inventory/distribution network design. The system addresses a class of distribution network design problem, which is characterized by multiple products family, multiple warehouses and retail-ers. The maximum capacity of vehicles and warehouses are also known. The res...
