Improving performance of electrical distribution companies, as the natural monopoly entities in electric industry, has always been one of the main concerns of the regulators. In this paper, a new incentive regulatory scheme is proposed to improve the performances of electrical distribution companies. The proposed scheme utilizes several efficiency assessments and a 3-dimentional reward-penalty ...

This study investigated the learning and assessment efficacy of a physics video game we developed called Newton's Playground. 165 8th and 9th graders played Newton's Playground for roughly five hours. Findings include significant pre-post physics gains and notable correlations between performance in Newton's Playground and physics pretest knowledge. Suggestions are given on how to develop asses...

The quality of video increased by the different enhancement techniques. In this paper we propose a video quality increasing technique by using tone adjustment. The human eye is very sensitive and very fascinating. The better quality video is proposed for human eyes. The quality of video cameras in ATMs, Shopping malls, and other heavy traffic areas is very poor. The increase of video quality fr...

Introduction: Standardized assessments are widely used by speech pathologists in clinical and research settings to evaluate the language abilities of school-aged children and inform decisions about diagnosis, eligibility for services and intervention. Given the significance of these decisions, it is important that assessments have sound psychometric properties. Objective: The aim of this system...

In this paper, we study the problem of video quality prediction over the wireless 4G network. Video transmission data is collected from a real 4G SCM testbed for investigating factors that affect video quality. After feature transformation and selection on video and network parameters, video quality is predicted by solving as regression problem. Experimental results show that the dominated fact...

Due to the increasing user expectation on watching experience, moving web high quality video streaming content from the small screen in mobile devices to the larger TV screen has become popular. It is crucial to develop video quality metrics to measure the quality change for various devices or network conditions. In this paper, we propose an automated scoring system to quantify user satisfactio...

By introducing video-quality adaptation mechanisms into intermediate network equipment using active network technologies, we can provide users with video distribution services that take into account client-to-client heterogeneity in terms of available bandwidth, performance of client systems, and user preferences for video quality. In this thesis, we design and implement an active video-quality...
