the term nanofluids was first coined by sir stephen choi in 1995 at argonne national laboratory ,u.s.a .since the discovery, nanofluid have been explored as heat transfer fluids. nanofluids increased the thermal conductivity of existing coolants (water, ethylene glycol) by a magnitude of hundred times which made them attractive for miniaturization of electronic devices .from 1995 till 2008 nano...

We study convective overshooting by means of local 3D convection calculations. Using a mixing length model of the solar convection zone (CZ) as a guide, we determine the Coriolis number (Co), which is the inverse of the Rossby number, to be of the order of ten or larger at the base of the solar CZ. Therefore we perform convection calculations in the range Co = 0...10 and interpret the value of ...

Educational organizations have different methods of deploying E-learning systems, of which is using and developing open-source e-learning systems. One should consider some criteria when choosing a suitable system includes: documentation, usage rate, structure, standards support and educational strategy. In this work an e-learning software system has been elected and five phases of modification ...

This paper presents the design of algorithms and a low-cost experimental setup for a graduate course on hybrid control systems offered to non-electrical engineering majors. The purpose of the developed hands-on educational kit is two-fold. First, it aims at incorporating in the classroom a basic yet important problem emerging in generation of renewable energy of current global relevance: optima...

The ninth month of Islamic calendar is known as Ramadan, in which fasting is obligatory for every adult man and woman, except in certain health conditions and during travelling. Since Islamic jurisprudence follows the lunar calendar, which is about 11 days shorter than the Gregorian, Ramadan falls in different seasons throughout the year. The duration of fasting hence may differ by 11 to 18 hou...
