Multicasting has emerged as one of the most focused areas in the field of networking. As the technology and popularity of Internet grow, applications, such as video conferencing, that require multicast feature are becoming more widespread. Another interesting recent development has been the emergence of dynamically reconfigurable wireless ad hoc networks to interconnect mobile users for applica...

Advances in technology have provided a continuing improvement in processor speed and capacity of attached main memory. The increasing gap between main memory and processor cycle times has required increasingly more levels of caching to prevent performance degradation. The net result is that the inherent delay of a memory hierarchy associated with any computing system is becoming the major perfo...

In next-generation wireless networks, OFDM is a potential key technology. Subcarriers in the OFDMA networks are scarce and valuable, operators should manage them efficiently by radio-resource management function. Several OFDMA subcarrier-allocation schemes and performanceevaluation methods have been widely studied, but very few studies focused on managing call blocking probability (CBP) and ban...

In this paper, we analyze the multi-cell multiuser interference through a new approach. The statistical eeect of hand-oo is considered. Diiering from the Gaussian approximation, an eecient method for evaluating the performance of a system with small number of users is developed.

background outcome determination of head trauma is important for medical decision-making. to determine the consequences by using ct findings, the marshall and rotterdam criteria were introduced. few studies have been conducted to determine the diagnostic value of the rotterdam criteria. objective this study assesses the diagnostic value of the rotterdam criteria score with early outcome for tra...
