The notion of entropy was first introduced in the 1850‘s by Rudolf Clausius in the context of thermodynamics. Focusing on the meaning that an increase of entropy means an increase of disorder, dissipation and decay, subsequent generations of authors have imported the notion into practically every area of intellectual discussion. This paper will mention numerous definitions of entropy and consid...

In this paper we present an intrinsically passive telemanipulation scheme over a digital transmission line Internet-like. We present an analysis of the energetic behavior of the communication line both in case of loss of packages and in case of variable delay. The sample data nature of the passive controller is explicitly taken into account following the approach outlined in [9] and [10].

The applications of Power-line communication (PLC) technology in medium voltage (MV) distribution networks are mainly related to the monitoring, control and metering functionalities. In order to design a robust communication system for MV-PLC grid, the frequency response of the channel and coupling devices has to be investigated. Scope of this paper is to present a theoretical model for a MV po...

Favourable sites for renewable generation are often remote locations (such as islands) where installed capacity, e.g. from wind turbines, exceeds local aggregate demand. We study the effect that curtailment mechanisms applied when there is excess generation have on the incentives to build additional capacity and the profitability of the generators. Next, for a two-location setting, we study the...

Starting with Maxwell's equations, the transmission line equations are derived for a system consisting of an arbitrary number of conductors. The derivation is rigorous for long lossless conductors embedded in a uniform perfect dielectric. The presentation is essentially tutorial, most of the results being well known, at least for twoand three-conductor systems. The novelty lies in the point of ...
