Using an Electric Differential (ED) in electric vehicle has many advantages such as flexibility and direct torque control of the wheels during cornering and risky maneuvers. Despite its reported successes and advantages, the ED has several problems limits its applicability, for instance, an increment of control loops and an increase of computational effort. In this paper, an electric differenti...

Three engraved limestone plaquettes from the recently excavated Epipaleolithic open-air site Ein Qashish South in the Jezreel Valley, Israel comprise unique evidence for symbolic behavior of Late Pleistocene foragers in the Levant. The engravings, uncovered in Kebaran and Geometric Kebaran deposits (ca. 23ka and ca. 16.5ka BP), include the image of a bird-the first figurative representation kno...

PURPOSE To determine why, despite growing evidence that radiologists and referring physicians prefer structured reporting (SR) to free text (FT) reporting, SR has not been widely adopted in most radiology departments. METHODS A focus group was formed consisting of 11 radiology professionals from eight countries. Eight topics were submitted for discussion. The meeting was videotaped, transcrib...

A nine-switch power converter having two sets of out-put terminals was recently proposed in place of the traditional back-to-back power converter that uses 12 switches in total. The nine-switch converter has already been proven to have certain advantages, in addition to its component saving topological feature. Despite these advantages, the nine-switch converter has so far found limited applica...

The disruptive innovation framework has become a topical issue in recent years. Despite its popularity, as well the perceived strategic advantages it bestows on entrant firms, little is known about capability of new-technology-based firms (NTBFs) South African context. This article explores contextual factors that influence Africa’s base-of-the-pyramid (BoP) environment and how, given spe...

Aiming further to reduce its switching losses, an appropriate discontinuous modulation scheme is proposed and studied here in detail to doubly ensure that maxi-mal reduction of commutations is achieved. With an appropriately designed control scheme had incorporated with nine-switch converter is shown to favorably raise the overall power quality and voltage mitigation hence justifying its role a...

Although fertility rates are falling in many countries, Europe is the continent with the lowest. As men and women choose to have fewer children, total fertility rates in Europe have fallen below replacement levels: for a total fertility rate of 1.5, the rate is around 1.7 children per woman for the cohorts born in 1965. This is due to individual decisions arising from the instability of modern ...

by the appropriate use of information technology, organizations can achieve sustainable competitive advantages. this technology because of including some characteristics such as being up-to-date, fast and precise and having different geographic localities all the time, has improved organizational efficiency, effectiveness and performance. in this article, we intend to investigate the role and e...
