Solar energy is quite simple as the can be obtained from sun directly. categorized one of best renewable since it does not emit carbon dioxide and because unlimited supports sun. In this paper, three main sections solar technologies like photovoltaicsolar panel, concentrating power, heating cooling system that available present days have been investigated. second part research, an experiment ha...

Listening to or speaking another language that we do not know or rarely use can be a daunting or even a frustrating experience in communication. Similarly, for language not to be addressed in content area, teaching and learning may hence do a disservice to students especially ones that find learning in another language challenging. Thus ‘Not knowing is hence not loving’, a literal translation f...

In wide area measurement systems, PMUs are the main component measuring real time synchronized data from different buses. Installation of PMUs at all buses is a primary way to provide full observability of the power network. However, it is not practical in real networks due to the relatively expensive cost of PMUs and other technical limitations. Optimal PMU Placement (OPP) is an optimization p...

The destructive impact of fading environments and also bandwidth limitations are two main challenges which communication is dealing with them. These challenges can affect on the growth of wireless communication and even cause reliable communications and high data rate to be prevented. Thus, OFDM (Orthogonal Frequency Division Multiplexing) modulation by using of fast calculation hardwares such ...
