Abstract— Frequency selective surface (FSS) is a repeated structure is transmitting, reflecting or absorbing based up on the mode of interest by using patches or slots. The patch and slot arrays effectively create band stop and band pass filters. The FSS have potential applications in...

Abstract: This paper simulates the mathematical model of the PV (photovoltaic) module based on the MATLAB script file with all the parameters are involved. Modeling this device environmental factors such as irradiation and temperature needs as input variables. The output of the PV module varies...

Light and materials are inseparably connected; indeed they actually determine each other: neither is visible to the human eye until the two come together. Light and materials are mutually dependent on each other. Materials are key to understanding light in architecture because they directly affect...

One of the best renewable source of energy that being used in the Philippines is the solar energy. It lessens or reduce carbon footprint and the use of fossil fuels, and because of its efficiency it helps the country to save electricity costs. The energy...

A diode is an electronic component allows current to flow easily in one direction but blocks current in the other direction. Most diodes are made from a silicon semi-conductor material. To make silicon a more effective semi-conductor the material goes through a process called doping....

Before the industrial revolution, humans relied on natural energy flows and animal and human power for heat, light and work. Draft animals, wind and water were the only sources of mechanical energy. The only form of energy conversion (from chemical energy to heat and light)...

Our current societies are run by, and depend on, electricity. From powering televisions to cellphones, electricity maintains many of elements of our modern culture. While some of these electric devices are powered using batteries or solar cells, nearly all important elements of daily life, both...

FUNDAMENTAL ASPECT OF SUPERCAPACITOR: Source of energy and environmental issues are the reason for development of renewable energy storage system. One of the them is supercapacitors called as ultra-capacitor and electrical double layer capacitor (EDLC). Supercapacitor store energy in the form of electric field, which...

The history of power generation is long and convoluted, marked by myriad technological milestones, conceptual and technical, from hundreds of contributors. This report will look at all the power generation sources conventional and non – conventional from a historic, economic, technological and safety perspective and...

This Major Corporation based out of America has dedicated its time and money towards Corporate Social Responsibility (CSR), and has satisfied interests of stakeholders unlike a myriad of companies like Enron and Volkswagen etc. CSR is a main part of General Electric’s sustainability strategy. General...

Introduction Electricity is a backbone of our existence in today’s world. It’s quite hard to imagine a world without electricity in the modern times. We are dependent on it for a major part of our day to day activities. However, electricity does not exist in...

Introduction Electric energy is moved from generating site ( source where it is converted from other form of energy) to load (where it will be used ) through high voltage transmission lines. High voltage is used to reduce energy loss, however it produces strong electric...

Introduction In these fast moving world renewable energy sources and storages plays crucial role to meet future end users requirement, in order to reach Australia’s commitment to reducing levels of greenhouse gas generation. However, there is uncertainty around these developments. To reach future generation requirements...

In the primitive years of electricity utilization, electricity systems were configured to supply power very close to the point of use. As time progressed, centralized large scale power generation was developed and became dominant, facilitated by technological advancement, the advantage of economies of scale, and...

Living in a house, self-owned or rented, the issue of maintenance regarding, plumbers, electricians, carpenters, door lock and key repair, painters are definitely going to crop up from time to time. Regarding Electrician in Grange in the case of a self-owned house, the owner is...

1. Introduction Renewable energy field is the majority of the current age because of its importance in developing the humanity. The demand for energy nowadays is going far greater than the generated energy. There are many renewable and nonrenewable energy sources like the fossil fuels...

Abstract— A miniaturized Gigahertz Transverse Electromagnetic (GTEM) Cell is designed and fabricated to generate uniform electric (E-) field, essential for studying the RF exposure effect on tissue equivalent liquids at Global System for Mobile (GSM) Communication frequencies (914MHz and 2.10GHz). The simulation procedure is discussed...

Dear Editor Hope you are fine and in full of your health and spirit. I am Harris and I have got an opportunity to write letter to you. This letter is about the frequent loadshedding in my area. There are many problems faced by the...

We now will study the various types of disturbances occurring in power system with their magnitude and duration: Complete interruptions: This is our country biggest problem when we study about power quality, the reasons are many. In the European standard EN 50160 two terms are...

ABSTRACT Forecasting electricity demand is very important for all producers and distributors. Liberalization trends affect electricity markets as well and reforms encourage new firms to enter the markets. This causes to rapid technological improvement and increase renewable types energy resources usage to produce electricity ....

Electrical energy is a traded commodity that is critical component of the daily life of consumers. There is an increasing demand for continuous access to power as consumers are increasingly critical of disturbance free power supply. Electrical disturbances occur at everything from planned to unplanned...

I’ve been really interested in renewable and sustainable energy sources for a while. While there are many sustainable, renewable energy sources that can be used on a large scale and sold to consumers, I will discuss smaller scale systems that can be implemented within an...

The imminent need for energy sources in human history takes us to analyse the history and potential of a well know market, the industry of batteries. When we think of batteries we not only reach the thought of an energy source, but we also must...

At this moment in time, with electricity demand around the world continuing to increase, one way we might reduce our reliance on non-renewable energies is to start using renewables, such as wind energy. Wind energy is set to have an increasingly significant part in the...

The input port can be idealized as either being a voltage input, which takes no current, with the output proportional to the voltage across the port; or a current input, with no voltage across it, in which the output is proportional to the current through...
