Cyberwarfare is defined as a new generation of war that uses computers and software to attack networks and acquire data or damage important infrastructures to get advantage in a military campaign. Nowadays, cyber espionage to obtain access to data bases is common. By using viruses or spyware hackers can invade military or governmental networks to get classified information in order to gain intelligence. An example was the cyber spy GhostNet supposedly used by China in 2009. According to the…

market area was examined relative to supply/demand and marketability vs. similar competing properties. A wide range of data was reviewed, considered and filtered in the process of collecting comparable sales for analysis and inclusion in the adjustment grid. These sources include the MLS, Assessor, knowledge of prior appraisals in the area and an awareness of a great multitude of other ongoing sources of information. Please see Appraiser's Certification, #12 & 13 and Statement…

This substantial distinction prompts to the loss of an electron from the less electronegative particle and the pickup of that electron by the more electronegative molecule, bringing about two particles. These oppositely charged particles feel a fascination in each other, and this electrostatic fascination constitutes an ionic bond. Ionic holding happens between a nonmetal, which goes about as an electron acceptor, and a metal, which goes about as an electron contributor. Metals have few valence…

1). In an article published by Charles Bryant (2015) titled, How Living off the Grid Works he states, “Wind power is the cleanest and cheapest energy technology in the world” (p. 3). The average price per kilowatt hour for coal-burning energy was 10.4 cents in 2006, while wind power costs just 3 cents per hour in ideal conditions.…

The panels use low power radio waves to transmit the solar power onto the receiving panels that are on earth. The power that is produced can supply to electrical sources. The design of space solar power is composed into three parts. There needs to be a 1.) a collector of the solar power, 2.) a way of transmitting power to earth and 3.) a way to receive the power on earth. There two methods of conversion…

Fixing climate change is not going to be done overnight, but it is urgent that we change now. It is possible, however, to make little adjustments which can lead to a better future. As stated previously, greenhouse gasses are being released and trapped in our atmosphere which eventually leads to the warming of the earth. The next step in fighting climate change is to invest in renewable resources and significantly reduce the use of fossil fuels. Whether someone wants to admit that climate change…

Apart from understanding theoretical concepts I believe in applying these concepts to solve real life problems, so I have actively participated in extracurricular interests. Higher education in Electrical Engineering at XYZ university will help me to enhance my research skills and knowledge gained during bachelors. The excellent environment for research, technical facilities and expert guidance of Professors of xyz university will definitely help…

these events occur, towers can be damaged or destroyed and the electrical power can be interrupted or terminated. In order to mitigate these communication challenges, one should consider the use of redundant systems in communication towers and electrical power. One such way to provide emergency power to communication systems is through the use of back-up generators that can help alleviate communication failures due to a faulty power grid (PBS, 2015). Additionally, the ability…

of nuclear reactors used around the world. The following chapter will explain the working of few of these nuclear reactors. 3.1 Pressurised Water Reactor (PWR) PWR is the most commonly use type of nuclear reactor, with over 230 of PWR used for electrical generation and several hundred more used for nuclear power naval ships/submarines. PWR reactors use water as both coolant and moderator. PWR works by having a primary cooling circuit using very high pressured water to flow through the core of…

 What is wind and how it works :- Wind is moving air and is caused by differences in air pressure within our atmosphere, Air under high pressure moves toward areas of low pressure , The greater the difference in pressure, the faster the air flows. Air may not seem like anything at all, in fact, we look right through it all the time, but during a windstorm, air really makes its presence known, Wind is able to lift roofs off buildings, blow down power lines and trees, and cause highway accidents…
