Energy Management in wireless ad hoc networks is a critical issue as energy resources are limited at the electronic devices used. Thus, energy efficient routing protocols are essential in wireless ad hoc networks to improve the life of network. This paper focuses on basic fundamentals and the classification of energy management schemes like, battery management system, transmission power managem...

The learning objects paradigm actually drives the majority of researches and commercial developments in elearning field. Nevertheless, this paradigm has been harshly criticized due to the fact that it has not achieved the objectives proposed in its initial definition. This, together with some false assumptions surrounding the e-learning concept, have led costumers and organizations to the belie...

Achieving dependability in large scale infrastructure systems always requires making intelligent tradeoffs. This paper proposes QAPSL, a systematic approach to making such tradeoffs with regards to application state management. We identify Quality, Availability, Performance, Security, and Lifetime as a set of fundamental state properties that can be traded against each other. We then describe a...

A lithium-ion capacitor (LiC) is one of the most promising technologies for grid applications, which combines energy storage mechanism an electric double-layer (EDLC) and a battery (LiB). This article presents optimal thermal management system (TMS) to extend end life (EoL) LiC technology considering different active passive cooling methods. The impact operating conditions stress factors such a...

Comparison of the theory of Rabi oscillations with experiment [M. Wilczewski and M. Czachor, Phys. Rev. A 79, 033836 (2009)] suggests that cavity lifetime parameters obtained in measurements with many photons may be much smaller than those applicable to almost vacuum states of light. In this context, we show that the conclusion remains unchanged even if one takes a more realistic description of...
