To draw humankind's attention to its existence, an extraterrestrial civilization could well direct periodic laser pulses toward Earth. We developed a technique capable of detecting a quasi-periodic light signal with an average of less than one photon per pulse within a measurement time of a few tens of milliseconds in the presence of the radiation emitted by an exoplanet's host star. Each of th...

New perspectives for the electric vehicle (EV) operation in smart grids and smart homes context are presented. Nowadays, plugged-in EVs are equipped with on-board battery chargers just to perform the charging process from the electrical power grid (G2V – grid-to-vehicle mode). Although this is the main goal of such battery chargers, maintaining the main hardware structure and changing the digit...

The integration of plug-in electric vehicles (PEVs) to power systems has impacts on the stability characteristics of the integrated systems. Wide area controllers (WACs) are used in power systems to provide auxiliary control signals to the generators or other devices in order to improve the stability of the system. The necessity of WACs becomes more relevant during grid-to-vehicle (G2V) or vehi...

Plug-in electric vehicles (PEVs) can serve in discharge mode as distributed energy and power resources operating as vehicle-to-grid (V2G) devices and in charge mode as loads or grid-to-vehicle (G2V) devices. It has been documented that PEVs serving as V2G systems can offer possible backup for renewable power sources, can provide reactive power support, active power regulation, load balancing, p...

A bi-directional power exchange between the plug-in electric vehicle (PEV) and AC electrical grid is necessary to perform Vehicle Grid (V2G) (G2V) operations. While performing these operations, different converters controllers play an important role as mediators PEV grid. Various works have demonstrated utilization of for PEV’s battery management. However, existing conventional technical shortc...

This article presents a comprehensive review on the reliability assessment and charging methodologies of electric vehicles (EVs) connected to grid. In transportation industry, EVs are acknowledged as effective ideas for reducing consumption fossil fuels emission greenhouse gases. The critical survey various types their performance, generally depend proper interface between power electronics con...

Abstract A key item of interest for planetary scientists and astronomers is the habitable zone: distance from a host star where terrestrial planet can maintain necessary temperatures in order to retain liquid water on its surface. However, when observing system’s zone, it possible that one may instead observe Venus-like planet. We define “Venus-like” as greenhouse-gas-dominated atmosphere occur...

Over the past decade, there has been a great interest in changeover from cars powered by gasoline to electric vehicles, both within automotive industry and among customers. The vehicle–grid (V2G) technology is noteworthy innovation that enables battery of an vehicle during idling conditions or parked can function as energy source store release whenever required. This results exchange between gr...

A number of space missions dedicated to the search for exo-planets via the transit method, such as COROT, Eddington and Kepler, are planned for launch over the next few years. They will need to address problems associated with the automated and efficient detection of planetary transits in light curves affected by a variety of noise sources, including stellar variability. To maximise the scienti...
