<p>Spectrum sensing in cognitive radio (CR) is a critical process as it directly influences the accuracy of detection. Noise uncertainty affects reliability detecting vacant holes spectrum, thus limiting access that spectrum by secondary users (SUs). In such uncertain environment; SUs sense received power primary user (PU) independently with different measures signal-to-noise ratio (SNR)....

To evaluate the drug utilization of third generation cephalosporins using core drug use indicators in various wards of Sri Ramachandra Hospital. Third generation cephalosporins are the most commonly prescribed broad spectrum antibiotic even before the culture sensitivity results arrives. Hence this study was undertaken to study the drug utilization evaluation of third generation cephalosporins ...

PURPOSE The purpose of this review is to provide guidance that aids in the practical design, implementation, and analysis of medication use evaluations (MUEs) for postsurgical pain management. SUMMARY Clinicians have long employed drug use evaluations or drug utilization reviews to ensure the safe and appropriate use of medications in a hospital, medical practice, or other healthcare setting....

BACKGROUND The high cost and undesirable consequences of polypharmacy are well-recognized problems among elderly long-term care (LTC) residents. Despite the implementation of the 1987 Omnibus Budget Reconciliation Act, which requires pharmacist review of drug regimens in this setting, medical and drug costs for LTC residents have continued to increase. OBJECTIVE This study evaluates the North...

The problem we investigate deals with the optimal assignment of resources to the activities of a stochastic project network. We seek to minimize the expected cost of the project include sum of resource utilization costs and lateness costs. We assume that the work content required by the activities follows an exponential distribution. The decision variables of the model are the allocated resourc...

The proliferation of high-volume time-critical web services such as online trading calls f o r a scalable server design that allows meeting individual response-time guarantees of real-time transactions. A main challenge is to honor these guarantees despite unpredictability in incoming server load. The extremely high volume of real-time service requests mandates constant-time scheduling and sche...
