Truly anyone can change the future. Back to the Future, a science fiction, action by Robert Zemeckis shows the audience many different themes. It tells how people shouldn’t abuse privileges, shouldn’t let “wants” get in the way of “needs”, and must always stand up for what they want. Despite all of these themes, there is one that is completely fool-proof and works for the story. Back to the Future tells people that they are in control of their own future, whether it’s dealing with bullies,…

Graphite, natural or synthetic, is composed of covalently bonded carbon atoms that are crystalline in structure due to Van der Waals attraction of its layered carbon sheets. It has a gray or black color, with thermal and electrical conductivity. With its properties, it can be used in many “industrial applications like in batteries and fuel cells” (Olson 2003). Although graphite has its useful characteristics, its performance is limited due to its large particles’ size resulting to “low aspect…

Chapter 5 Hybridization of Wind With Solar Using Cuk and Sepic Converters This chapter presents a hybrid model of solar and wind energy. This gives the hybridization of wind with solar using the CUK and SEPIC converters. In this model the solar PV panel source is connected to the CUK converter and correspondingly the wind turbine source is given to the SEPIC converter. Solar energy and wind energy are the two renewable energy sources most common in use. Hybridizing solar and wind power sources…

I first realized I wanted to pursue a career in Electronics Engineering when I took an Electronics class in high school. I got interested in how electricity works in all the technology that we use today in our modern world. I was also curious about how a device with a screen is able to display words and pictures. I also want to learn programming because it deals a lot with electronics. Programming shows how we communicate and tell devices what to do. Without programming, devices wouldn’t do…

Surveillance is defined as it is the monitoring of activities, behavior or changing information usually of people for the purpose of influencing ,directing or protecting purpose. The word surveillance is French word “ watching over”, ‘sur’ means “from above ” and ‘veiller’ means “to watch”. Surveillance is also observation from a distance by means of electronic equipment. Surveillance is one of the most important security system in today’s life as it protects home from theft , burglaries and…

is a circuit where a battery, resistor (with resistance R), an inductor (with inductance L) and a capacitor (with capacitanceC), RLC, are all connected in one complete loop (a series circuit) (Wood.D,2003). It occurs when resistive and inductive are equal in magnitude however it cancels each other because they are 180 degrees apart in phase. When Appling alternative voltage to an inductor, capacitor and resistance Q3.Describe the construction and operation of a brushless ac generator.…

In 1918, the principle of utilising an electromagnetic force to fire projectiles was discovered but focus on railguns have only been intensified since 2012, when the first weaponized rail gun was released by the US navy. Since then, the railgun has been believed to be a powerful weapon that will overshadow other conventional weapons. This investigation is to determine if railguns should replace conventional weapons in the future. Electromagnetic railguns are long range weapons that fires…

Hayden Gregory and Ben Ludwig Creative Writing Opportunities “Stop Larry!” shouted Harry as Larry discombobulated Harry, as he was working on the toy flux-capacitor next to the toy chainsaw. Larry was frolicking around instead of doing his chores. Larry and Harry are brothers, so close they gave each other anklets. Larry wasn’t a very good student, although he was extremely smart. He doesn’t turn in his homework on time or study enough to get grades he deserved. One day, he was…

Fig. 3. Schematic Diagram of Power Line Guardians (“PLG”) PLGs are also used to give the real-time data on the lines such as: line current, conductor temperature, frequency, sag [17]-[21]. Fig. 4. The PLG communications system. The diagram (Fig.4) shows the PLG communications system. PLGs (blue) control the power flows on the lines. Super PLGs (red) can control both the power flows and the PLGs. These Super PLGs are also used to communicate with Energy Management Systems (EMS) and allow…

According to maximum power transfer theorem, power delivered by the source to the load is maximum when the internal source impedance is approximately equal to the load impedance [138]. The output power of the PV panel is variable according to the solar irradiance and temperature as shown in Figure 4.7. Therefore, internal impedance of the PV panel is also variable according to variation in solar irradiance and temperature. Figure 4.7 Characteristic of PV panel at variable solar…
