Online education in Nigeria is a recent phenomenon that is embraced by the populace. Some Two decades ago, online education was unthinkable but with the present realities such as internet and enhanced technology, Nigerians are experiencing transformation in learning and new fields of educational research. The National Open University of Nigeria (NOUN), identified with the Federal Government of ...

Energy efficiency in large data centers is already a concern for many businesses because of the high density of energy consumption. Rising energy costs and global environmental concerns have prompted Information Technology (IT) professionals to also take a closer look at client personal computer (PC) energy consumption. Intel researchers interviewed IT professionals about the monitoring and con...

The increase of the processing power of personal computers in the last decade resulted in a notable progress of the artificial animal (animat) construction and simulation field. Regardless of the achieved results the coding of an animat’s behavior can, to someone unfamiliar with physics of motion and robotics, seem like pure witchcraft. Not to mention the wealth of ethological knowledge require...

Recently, short animated image sequences have become very popular in social networks. Most animated images are represented in GIF format. In this paper we propose an animated JPEG format, called aJPEG, which allows the standard JPEG format to be extended in a backward compatible way in order to cope with animated images. After presenting the proposed format, we illustrate it using two prototype...

RÉSUMÉ. Le web évolue vers des contenus intégrant des médias de plus en plus riches et variés accédés à l’aide d’appareils très divers à travers de multiples réseaux. Cet environnement très hétérogène, mobile et changeant nécessite que les informations multimédias envoyées par les serveurs soient adaptées aux conditions précises de leur utilisation. Pour répondre à cette adaptation, un ensemble...

The Information Power Grid (IPG) is intended to integrate a nationwide network of computers, databases, sensors, and instruments into a seamless whole that appears to be part of a user's personal computer. In other words, with an advanced IPG you could negotiate temporary remote access to all of the computing power, software, specialized instruments, and information that you might otherwise hav...

Today, many scientific and engineering areas require high performance computing to perform computationally intensive experiments. For example, many advances in transport phenomena, thermodynamics, material properties, computational chemistry and physics are possible only because of the availability of such large scale computing infrastructures. Yet many challenges are still open. The cost of en...
