nowadays the position of the renewable energy is so important because of the environment pollution and the limitation of fossil fuels in the world. energy can be generated more and more by the renewable sources, but the fossil fuels are non-renewable. one of the most important renewable sources is the wind energy. the wind energy is an appropriate alternative source of fossil fuel. the replacem...

Note: To follow this note and especially to get definitions of concepts as lower catchment basin, FOZ, dual geodesic reconstruction, I STRONGLY recommend to read the following documents available on my Web page (http://cmm.ensmp.fr/~beucher/publi.html): P algorithm, a dramatic enhancement of the waterfal transformation (http://cmm.ensmp.fr/~beucher/publi/P-Algorithm_SB_BM.pdf, in particular, pa...

In the most described maximum power point tracking (MPPT) methods in the literatures, the optimal operation point of the photovoltaic (PV) systems is estimated by linear approximations. However, these approximations can lead to less optimal operating conditions and significantly reduce the performances of the PV systems. This paper proposes a new approach to determine the maximum power point (M...

Eight years after the Lawrence Inquiry, the question of police powers to stop and search people in public places remains at the forefront of debate about police community relations. Police are empowered to stop and search citizens under a wide range of legislative acts and the power is employed daily across Britain. Far from laying the debate to rest, the Lawrence Inquiry prompted new research ...

oscillating reactions are one of the most interesting topics in chemistry and analytical chemistry. fluctuations in concentrations of one the reacting species (usually a reaction intermediate) create an oscillating chemical reaction. in oscillating systems, the reaction is far from thermodynamic equilibrium. in these systems, at least one autocatalytic step is required. developing an instinctiv...

In this paper, we propose a system which automatically generates slideshows for music, by utilizing images retrieved from photo sharing web sites, based on query words extracted from song lyrics. The proposed system consists of two major steps: (1) query extraction from song lyrics, (2) image selection from web image search results. Moreover, in order to improve the display duration of each ima...

The Point-to-Point Tunneling Protocol (PPTP) is used to secure PPP connections over TCP/IP link. In response to [SM98], Microsoft released extensions to the PPTP authentication mechanism (MSCHAP), called MS-CHAPv2. We present an overview of the changes in the authentication and encryption-key generation portions of MSCHAPv2, and assess the improvements and remaining weaknesses in Microsoft’s PP...
