ramadan fasting has been a major concern among researchers considering the theoretically imposed risk on patients with diabetes mellitus due to prolonged fasting. studies indicate that the knowledge and practices of physicians do not comply with the proposed recommendations in this regard in many cases. this study aimed to explore the viewpoints and attitudes of physicians toward the management...

A scheduling problem that includes different hardware delays experienced by the secondary users (SUs) while switching to different frequency bands in a centralized cognitive radio network (CRN) is formulated. A polynomial-time suboptimal algorithm is proposed to reduce the scheduling problem. The impact of varying switching delay, number offer quencies, and number of SUs is evaluated. The simul...

Materials such as waste tire chips were widely used to improve the strength of soil. The objective of this study is to discuss the residual strength or steady-state behavior of sand-waste tire chip mixtures. A series of undrained monotonic triaxial compression tests were conducted on reconstituted saturated specimens of sand and sand-tire chip mixtures with variation in the tire-chip contents f...

Traditional beamforming and power control algo-rithms in cognitive radio (CR) are based on the assumption of perfect channel state information (CSI) however; this may lead to performance degradation in realistic systems. In this paper, the problem of joint beamforming and power control is investigated in underlay CR networks with imperfect CSI. Our objective is to maximize the sum utility of se...

Among a number of classes of oral antihyperglycemic drugs, sulfonylureas (SUs) demonstrating the potential effect to reduce blood glucose level have been used in a majority of patients with type 2 diabetes for many years. The pathophysiological processes by which SUs adversely induce the risk of cardiovascular disease have not been fully clarified. We summarized about the relationship between S...

Cognitive Radio (CR) is a promising technique to address the spectrum scarcity issue by enabling the unlicensed network users (SUs) to dynamic access the spectrum holes. This thesis designs Medium Access Control (MAC) protocols for SUs to utilize the unused spectrum without interfering the licensed network users’ (PUs) transmissions; analyzes the MAC performance based on the queuing theories; a...

We propose a distributed spectrum access algorithm for cognitive radio relay networks with multiple primary users (PU) and multiple secondary users (SU). The key idea behind the proposed algorithm is that the PUs negotiate with the SUs on both the amount of monetary compensation, and the amount of time the SUs are either (i) allowed spectrum access, or (ii) cooperatively relaying the PU’s data,...

In the case of on-line action role-playing game, the combat strategies can be divided into three distinct classes, Strategy of Motion(SM), Strategy of Attacking Occasion (SAO) and Strategy of Using Skill (SUS). In this paper, we analyze such strategies of a basic game model in which the combat is modeled by the discrete competitive Markov decision process. By introducing the chase model and the...

A sequential updating scheme (SUS) for belief propagation (BP) decoding of LDPC codes over Galois fields, GF (q), and correlated Markov sources is proposed, and compared with the standard parallel updating scheme (PUS). A thorough experimental study of various transmission settings indicates that the convergence rate, in iterations, of the BP algorithm (and subsequently its complexity) for the ...

The paper offers a historical retrospective of Brazil's Sistema Único de Saúde (SUS), including its background and its legacy on its current design. It begins describing some of the system's structural problems, especially the co-existence of a public system alongside a private one. It identifies problems that have hampered a firmer solidification of SUS, while it also highlights the immense im...
