Abstract— This paper, considers a marketed small-cell caching system comprising of a Network Service Provider (NSP), a number of Video Retailers (VR), and Mobile Users (MU). The NSP rents its SBSs to the VRs intending benefits. Stackelberg game framework is used for addressing the SBSs as a particular type of resources. The MUs and SBSs as autonomous Poisson Point Processes (PPP) are used to de...

Our paper reports on the use of data envelopment analysis (DEA) for the assessment of performance of secondary schools in Malaysia during the implementation of the policy of teaching and learning mathematics and science subjects in the English language (PPSMI). The novelty of our application is that it makes use of the hybrid returns-to-scale (HRS) DEA model. This combines the assumption of con...

The Visual Analogue Scale (VAS), Numerical Rating Scale (NRS), Verbal Rating Scale (VRS), and the Faces Pain Scale-Revised (FPS-R) are among the most commonly used measures of pain intensity in clinical and research settings. Although evidence supports their validity as measures of pain intensity, few studies have compared them with respect to the critical validity criteria of responsivity, and...

BACKGROUND Intra-articular analgesia is a pain reliever that is frequently administered following arthroscopic knee surgery. OBJECTIVES The purpose of this study was to compare the efficacy of intra-articular application of morphine and tramadol on postoperative pain after arthroscopic knee surgery. PATIENTS AND METHODS For this randomized double blinded clinical trial, 132 patients undergo...

Learning from high performance projects is crucial for software process improvement. Therefore, we need to identify outstanding projects that may serve as role models. It is common to measure productivity as an indicator of performance. It is vital that productivity measurements deal correctly with variable returns to scale and multivariate data. Software projects generally exhibit variable ret...

This study aims to determine the level of efficiency maternal health services, explain factors that cause inefficiency in districts/cities province East Java. Using data envelopment analysis (DEA). The results showed variable return scale (VRS) test were better than constant (CRS), there was a change from relatively inefficient using VRS efficient regions VRS. partial regression AAB affect inef...

BACKGROUND Virchow-Robin spaces (VRS) or perivascular spaces are interstitial cystic spaces surrounding the vasculature of brain parenchyma and course from the subarachnoid space. Small VRS (<2 mm) appear in all age groups, but can enlarge and be confused with other lesions like cystic neoplasms. These enlarged VRS are termed giant tumefactive perivascular spaces (GRPVS). CASE DESCRIPTION We ...

The apparent difficulty people have with making Bayesian inferences has been researched heavily over the past 25 years, with conflicting explanations regarding the causes of and the cures for this inadequacy. Some researchers have improved Bayesian reasoning by representing the problem visually, but usually as a tool to teach Bayesian reasoning skills. This research examines facilitating reason...

An Unlinkable Sanitizable Signature scheme (USS) allows a sanitizer to modify some parts of a signed message such that nobody can link the modified signature to the original one. A Verifiable Ring Signature scheme (VRS) allows the users to sign messages anonymously within a group such that a user can prove a posteriori to a verifier that he is the signer of a given message. In this paper, we fi...

Magnetic data consists of a sequence of collected points with spatial coordinates and magnetic information. The spatial location of these points needs to be as exact as possible in order to develop a precise interpretation of magnetic anomalies. GPS is a valuable tool for accomplishing this objective, especially if the RTK approach is used. In this paper the VRS (Virtual Reference Station) tech...
