In this paper a dynamic spectrum access (DSA) concept is explored for mitigating awid sr-2400 the paucity of spectral bandwidth in cognitive radio (CR) for opportunistic, dynamic access of the spectrum without any interference.Dynamic spectrum access schemes are proposed for a distributed cognitive radio network consisting of one secondary user (SU
PurposeNephrolithiasis is thought to be a risk factor for osteoporosis, but data assessing if osteoporosis predisposes to the risk of nephrolithiasis are lacking.The present study aims to investigate whether patients with nephrolithiasis have a prominently higher prevalence of osteoporosis than the controls and vice versa via a cumulative analysis.
Image quality assessment (IQA) algorithms aim to reproduce the human’s perception of the image quality.The growing popularity of image enhancement, generation, and recovery models instigated the development of many methods to assess their performance.However, most IQA solutions are designed to predict image quality in the general domain, wit
Hypersonic aircraft represent an important area of aerospace development.Raising the aircraft lift-to-drag ratio, fifty fifty truckee improving the efficiency of attitude control, and optimizing aerodynamic performance are important goals.Active flow control technology can improve the aerodynamic performance of the aircraft while optimizing its con
