The aim of this paper is to examine the education problems in Africa which include lack of proper schooling facilities and educators, emigration, military and conflict. Special reference is given to the most important problem that is educational systems of countries that do not serve the needs of today graduated students and make them not competiti

As applied to differential geometry it provides a method to describe differential algebraic $H$-invariants of paths by the use of algebraic $H$-invariants, where $H$ is any subgroup of the affine group. It is shown also that a generating system of differential $H$-invariants of curves can be derived from given system of differential $H$-invariants

Three structurally distinct forms of phosphoglycerate mutase from the trypanosomatid parasite Leishmania mexicana were isolated by standard procedures of bacterial expression and purification. Analytical size-exclusion chromatography coupled to a multi-angle scattering detector detected two monomeric forms of differing hydrodynamic radii, as well a

The work aims to study the performance of suspension systems for off-road vehicles. Three type of suspensions-passive, hybrid semi-active and Linear Quadratic Regulator (LQR) active suspension systems are presented using half-car model. These systems are compared in terms of ride quality, handling, road holding and ability to support vehicle static

Use of Online Social Networking Sites (OSNs) has become ubiquitous nowadays. In the era of a million user social networking sites throughout the world, it becomes increasingly difficult for people to control what they are exposing to whom. In this paper we analyze the influence of social media interactivity features on the exposure of personal data

This research introduces a virtual interface between Windows 7 and LINUX Fedora 16 based on Virtual Machine ware (VMware) for real-time Malaysian Sign Language (MSL) translation into text and/or voice (in English). The developed method is based on HTK, Gt2k under LINUX Fedora 16 and VC++ 2010 and OpenCV pre 1.1 library under Windows7. The communica

Fabricating electrostatic micro actuator, such as comb-drive actuator, is one of the demanding areas of the MEMS technology because of the promising applications in modern engineering, such as, micro-switches, attenuators, filters, micro-lenses, optical waveguide couplers, modulation, interferometer, dynamic focus mirror, and chopper. For the fabri

Throughout the technological advancements, electronic devices are getting high dense and less expensive in day by bay. Thus, significantly reducing the production cost is the vital issue in order to produce more competitive device with maintaining its standard in all expect. Therefore, introducing new compact contact in high-Hertz stress with low n

By employing VECM, Indonesia denotes that monetary policy shock in the short term stimulates significant shocks in the long term, whereas Malaysia experienced a stability trend showed by soft movement in the short term. As for Sudan, by employing VAR since no cointegration, it has a similar pattern with that of Malaysia indicated by IRF result. The

The main role of a suspension system of a vehicle is to prevent the road excitations from being transmitted to the passengers. In this study, we develop and obtain a strategy to optimise the main design parameters of a semi-active suspension for a two-axle full off-road vehicle. The objective is to minimise the maximum bouncing acceleration of the
