The Performance of electric vehicle IGPT Pin fin heat sink can be measured by the temperature field and the fluid pressure and other parameters. In order to improve the cooling effect of Pin fin heat sink, diameter, length and distance of the fin was optimized combination. The relationship between pressure drop of the water inlet, outlet and pin fin parameters was analyzed and calculated. It wa...

The application model for the energy consumption of a node as a function of its throughput in a wireless CSMA network. We first model a single-hop network, and then a multi-hop network. We show that operating the CSMA network at a high throughput is energy inefficient since unsuccessful carrier sensing attempts increase the energy consumption per transmitted bit. Operating the network at a low ...

This study investigates the effect of using Fume Silica (Aerosol 300) alone and together with crumb rubber (CR) in bitumen modification on traditional rheological properties binder compares it to SBS modified binder. Using aerosol additive at rates 0.5%, 1%, 1.5%, 2% were determined as most convenient ratio CR+aerosol binders prepared per this ratio. The subjected softening point, viscosity, fr...

Currently, due to increased competition in the services and manufacturing, many companies are trying to lower price and good quality products offer to the market. In this paper, the multi-criteria decision-making techniques to evaluate and select the best supplier from among the existing suppliers. The first, hierarchical structure for selecting suppliers of raw materials used and the analytic ...
