background: electronic learning (e-learning), is the use of electronic technology in education via computer and the internet. despite its slow adoption by faculty members, e-learning provides several benefits to individuals and organizations. this study was conducted to determine the factors influencing the adoption of e-learning by faculty members in tabriz university of medical sciences.    m...

Realistic simulation of crowds is an important issue for the production of virtual worlds for games, entertainment or architectural and urban planning. Difficult issues need to be addressed such as collision avoidance and the handling of dynamic environments. In this paper, we present a unified structure for the simulation of complex urban environments. We propose a topological multiresolution ...

Objective- The aim of this study was preparing detailed anatomic images of the thoracic cavity of the southern white-breasted hedgehog using the non-invasive computed tomography (CT) technique.Design- Descriptive study.Animals- Five southern white-breasted hedgehog (Erinaceus concolor) which is a species native to the Middle East, Anatolia, Transcaucasia, and Iran. Since some people...

Imputation is one of the most common methods to reduce item non_response effects. Imputation results in a complete data set, and then it is possible to use naϊve estimators. After using most of common imputation methods, mean and total (imputation estimators) are still unbiased. However their variances (imputation variances) are underestimated by naϊve variance estimators. Sampling mechanism an...

The relationship between the topology of interconnection networks and their functional properties is examined. Graph theoretical characterizations are derived for delta networks , which have a simple routing scheme, and for bidelta networks, which have the delta property in both directions. Delta networks are shown to have a recursive structure. Bidelta networks are shown to have a unique topol...

By summarizing Khachiyan's algorithm and Karmarkar's algorithm forlinear program (LP) a unified methodology for the design of polynomial-time algorithms for LP is presented in this paper. A key concept is the so-called extended binary search (EBS) algorithm introduced by the author. It is used as a unified model to analyze the complexities of the existing modem LP algorithms and possibly, help ...
