A Radial Distribution network is important in power system area because of its simple design and reduced cost. Impact of Distributed generation in radial distribution feeder is increased because of its application of green technology and it also meet out some of the power system issues. Allocation of Distributed Generation at non-optimal places leads to increased power loss and reduced bus volt...

Many production facilities generate and update production schedules. Rescheduling is necessary because the manufacturing system is dynamic and unexpected events occur. This paper discusses rescheduling policies and how they affect the performance of manufacturing systems. The benefits of proper rescheduling include improved manufacturing system performance with reduced cost due to computational...

Antennas are becoming crucial in an increasingly growing number of applications namely with the emerging of the wireless internet communications, military systems like aircrafts, missiles and submarines or even oil drilling systems where efficiency, compactness and cost play a decisive role. Nonetheless, a major drawback of such solutions is that the aforementioned criteria are hard to simultan...

There is growing interest in the notion of software development through the planned integration of COTS (Commercial Off-The-Shelf) products. The potential advantages of this integrationcentric approach are shorter development time and reduced cost. Often a COTS based development process consists of an evaluation, selection, adaptation, integration, and evolution of components obtained from exte...

Infrastructure-as-a-Service (IaaS) cloud providers offer a number of different tariff structures. The user has to balance the flexibility of the often quoted pay-by-the-hour, fixed price (“on demand”) model against the lower-cost-per-hour rate of a “reserved contract”. These tariff structures offer a significantly reduced cost per server hour (up to 50%), in exchange for an up-front payment by ...

Explaining the maintenance of sexual reproduction remains one of the greatest challenges in biology. The theoretical oddity of sex is based on at least three advantages that asexual organisms have over sexual ones: 1Asexuals, by not producing males, have a two fold advantage over sexuals, regarding the number of reproductive individuals; 2Sexuals have an evolutionary disadvantage over asexuals,...

In this paper, we present a virtual laboratory platform (VLP) baptized Mercury allowing students to make practical work (PW) on different aspects of mobile wireless sensor networks (WSNs). Our choice of WSNs is motivated mainly by the use of real experiments needed in most courses about WSNs. These experiments require an expensive investment and a lot of nodes in the classroom. To illustrate ou...

Quality education can be delivered at a time, place and pace that suit the learner, teacher and administrator. One way to achieve this is for universities to devise an appropriate and effective web based education environment that supports customization for the individual. Such an environment requires interoperability of heterogeneous systems, reduced cost through re-use of existing invested te...

INTRODUCTION The main scope of this article is to present a heuristic model to deploy government-to-government initiatives effectively, as well as establish some key success factors for building governmentto-government (G2G) enterprises successfully. It also aims to show how public agencies themselves can benefit when they are electronically linked to others, thereby innovating and streamlining...

As the underlying technologies evolve, embedded systems are finding their way into an increasing range of ABB products and applications. Advances in this technology lead to higher performance and more functionality on the one hand, and reduced cost and size on the other. While this benefits the end user, the ever increasing complexity of embedded systems imposes new challenges for developers. T...
