The need to transmit data over Internet is increasing at a very fast pace, which requires techniques that can considerably reduce the size of images so that they occupy less space and bandwidth for transmission. In this paper, we have used Kohonen’s self organizing map (SOM) network, which is a class of neural networks, for image compression and feature extraction. Moreover, a global processing...

Abstract— We evaluate the effects of mobility and reservations on new call blocking and handoff blocking We evaluate the effects of mobility and reservations on new call blocking and handoff blocking in multirate wireless networks. The model evaluated uses Fixed Channel Assignment (FCA) with priority for handoffs over new call arrivals by reserving a number of channels for handoff calls in all ...

We analyze the distribution of broadcasting revenues by sports leagues. In the context of an isolated league, we show that when the teams engage in competitive bidding to attract talent, the league's optimal choice is full revenue sharing (resulting in full competitive balance) even if the revenues are independent of the level of balancedness. This result is overturned when the league has no mo...

The network revenue management (RM) problem arises in airline, hotel, media, and other industries where the sale products use multiple resources. It can be formulated as a stochastic dynamic program, but the dynamic program is computationally intractable because of an exponentially large state space, and a number of heuristics have been proposed to approximate its value function. In this paper ...

transmission network expansion planning (tnep) is an important component of power system planning. itdetermines the characteristics and performance of the future electric power network and influences the powersystem operation directly. different methods have been proposed for the solution of the static transmissionnetwork expansion planning (stnep) problem till now. but in all of them, stnep pr...
