The actual research in terms of energy focuses drastically on the use green resources. Hydropower systems have been most known sources for years. However, hydropower systems, which are seasonal and exploited, do not cover speed increasing daily demand. injection solar power could be a supporting alternative, but it is only daylight, weather dependent intermittent. Therefore, storage system requ...

We have made a clear detection of p-mode oscillations in the nearest solar-like G2V star α Cen A with the CORALIE spectrograph on the 1.2-m Swiss telescope at the ESO La Silla Observatory. We report the 5 nights of observation on this star in May 2001 during which 1260 high precision radial velocity measurements were obtained. The power spectrum clearly shows several identifiable peaks between ...

Batteries of electric vehicles (BEV) are becoming more attractive with the advancement of new battery technologies and promotion of electric vehicles. BEV batteries are recharged on board vehicles using either the grid (G2V for Grid to Vehicle) or renewable energies in a stand-alone application (H2V for Home to Vehicle). This paper deals with the modeling, sizing and control of a photovoltaic s...

Saving energy through the minimization of power losses in a distribution system is key activity for efficient operation. Distributed Generation (DG) one most approaches to minimize losses. With increase installation Electric Vehicle Charging Stations (EVCSs) Electrical Vehicles (EVs) larger scale, optimal planning EVCSs becomes major challenge operator. increased EV load penetration electricity...

This paper presents the performance evaluation of a proposed single-phase bidirectional active neutral-point-clamped (ANPC) five-level converter (5LC) for filtering in grid-to-vehicle (G2V), vehicle-to-grid (V2G) and vehicle-to-home (V2H) applications. In system, 5LC is series-connected with an electric vehicle battery charger based on dual half-bridge DC-DC (DAHBC). A cascaded strategy proport...

Brown dwarfs and low-mass stellar companions are interesting objects to study since they occupy the mass region between deuterium and hydrogen burning. We report here the serendipitous discovery of a low-mass companion in an eccentric orbit around a solar-type main-sequence star. The stellar primary, TYC 2534-698-1, is a G2V star that was monitored both spectroscopically and photometrically ove...

Plug-in electrical vehicles (PEV) are capable of both grid-to-vehicle (G2V) and vehicle-to-grid (V2G) power transfer. The advantages of developing V2G include an additional revenue stream for cleaner vehicles, increased stability and reliability of the electric grid, lower electric system costs, and eventually, inexpensive storage and backup for renewable electricity. Here we show how smart con...

In vivo hematopoietic generation occurs in waves of primitive and definitive cell emergence. Differentiation cultures of pluripotent embryonic stem cells (ESCs) offer an accessible source of hematopoietic cells for blood-related research and therapeutic strategies. However, despite many approaches, it remains a goal to robustly generate hematopoietic progenitor and stem cells (HP/SCs) in vitro ...
