—Cognitive radio network maximizes number of secondary users (SUs) without affecting the service of primary users (PUs). Admittance of SUs is not only affected by the path loss but also log-normal shadowing. In this paper, we have carried out the simulation study of joint admission and power control (JAPC) algorithms: JAPC-MRER and JAPC-MSSRA in presence as… (More)

This paper examines the nature of IMF Management and senior staff concerns about excessive reserve accumulation. It describes how the IMF's concerns regarding global imbalances before the crisis evolved into concerns about reserve accumulation in the crisis aftermath, and explores why this may have occurred. It assesses why the recent concerns about reserve… (More)
INTRODUCTION Giant cell tumor accounts for 5 to 9 percent of all primary bony tumors. Giant cell tumors are usually found in the long bones, most often the distal femur, proximal tibia, distal radius and rarely arising from the ribs. In this paper, we describe a case of giant cell tumor presented at an unusual location of the costovertebral junction as a… (More)
In this chapter, the authors study the performance of Cooperative Spectrum Sensing (CSS) with soft data fusion, given by Maximal Ratio Combining (MRC)-based fusion with Weibull faded channels, and Log-normal shadowed channels. More precisely, they evaluate the performance of a MRC-based CSS with Cognitive Radios (CRs) censored on the basis of the quality of… (More)
IMF response to the financial and economic crisis.
Health information exchange is expected of all electronic health records (EHRs) in order to ensure safe, quality care coordination. The U.S. Department of Veterans Affairs (VA) has a long history of information exchange across VA facilities and with the U.S. Department of Defense (DoD). However, since a majority of VA and DoD patients receive a portion of… (More)
