Cooperative spectrum sensing (CSS) is able to effectively solve the hidden terminal, depth attenuation, multipath shadows and other issues which are not addressed by the single-user sensing. Therefore, it has attracted a large amount of interest and several CSS algorithms have been proposed. However, they are not specifically tailored for cognitive wireless sensor networks (CWSNs) where transmi...

INTRODUCTION We sought to validate radiographic measurements of range of motion of the knee after arthroplasty as part of a new system of virtual clinics. METHODS The range of motion of 52 knees in 45 patients was obtained by 2 clinicians using standardised techniques and goniometers. Inter-rater reliability and intraclass correlation coefficients (ICCs) were calculated. Radiographs of these...

BACKGROUND Medication adherence is critical in Tuberculosis (TB) treatment success, but existing tools are inadequate in identifying non-adherents, reasons for non-adherence or interventions to improve adherence. This study intended to fill the gap by developing and validating a TB medication adherence scale (TBMAS). METHODS An initial 41-item TBMAS was designed through review of literature, ...

The increasing complexity of industrial systems requires the adoption of adequate approaches to manage emergency situations in case of accidents and disasters. In this context the analysis of human reliability represents a crucial task [2]. In fact, the human factor is a predominant element in the study of accidents/disaster, both in probability level, but also in terms of severity of the expec...

Directed motivational current (DMC) ̶ as a novel strand in L2 motivational field ̶ is a robust motivational drive fueled by a highly valued goal and capable of stimulating and sustaining long-term behavior. The present study explored English as a foreign language students’ Directed Motivational Currents by validating the dynamic web-based Persian version of the scale, finding the most crucial mot...

background: low health literacy (hl) of patients has obtained more attention as a risk factor for poor adherence to treatment and adverse outcomes in chronic disease’s management particular in diabetes care. diabetes numeracy test‑15 (dnt‑15) has been developed specifically for this purpose. the objective of the current study is to evaluate psychometric properties of iranian (persian) version o...

abstract background: application of a reliable and authentic behavioral tool for measuring patients’ pain, hospitalized in intensive care units who are not able to establish relationship, is needed severely. therefore, this study is conducted with the aim of validating critical care pain observation tool (cpot) in patients hospitalized in surgical wards. materials and methods: cpot was first tr...
