The Performance of Distance EducationVideo in

چکیده
The tremendous growth in both Java and multimedia present an opportunity for cross-platform distance education systems exploiting the power of audio and video to enhance the education process. However, little research has been done on evaluating Java multimedia performance nor on assessing its viability as a platform for distance education. In this paper, we present experiments that measure the multimedia performance of an MPEG-1 client in Java, and evaluate its potential as a distance education platform considering both video frame rate and jitter. We nd Just-In-Time compilation, local media access and processor choice signiicantly aaect multimedia performance, while choice of operating system, Java virtual machine and garbage collection have a negligible eeect on multimedia performance. While overall Java still lags considerably behind multimedia performance in C++, suitable video performance can be achieved in Java, which, if carefully deployed, promises to enhance distance education systems.

Genetic Distance Based on SSR Markers and Testcross Performance of Maize Inbred Lines
The identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. In some cases, pedigree information has been used to select diverse parental lines. In the case of Iranian maize inbred lines, this information is not fully available. In this study we investigated the genetic distance (GD) based on Simple sequence Repeats (SSR) ...

The purpose of this paper is to introduce a new estimation method for estimating the Archimedean copula dependence parameter in the non-parametric setting. The estimation of the dependence parameter has been selected as the value that minimizes the Cramér-von-Mises distance which measures the distance between Empirical Bernstein Kendall distribution function and true Kendall distribution functi...

This paper considers the search problem, introduced by Srivastava cite{Sr}. This is a model discrimination problem. In the context of search linear models, discrimination ability of search designs has been studied by several researchers. Some criteria have been developed to measure this capability, however, they are restricted in a sense of being able to work for searching only one possibl...

The present study examined the effectiveness of distal versus proximal external foci of attentions a function of performers’ preferences for a certain focus. dart throwing task were used, and participants (N=20) were instructed to direct their attention either to the target (distal focus) or the flight of the dart (proximal focus). Participants were asked to select their preferred focus aft...
