depressed, self-pitying teenager with little ambition. However, Ferris coerces him to go on an adventure through the city of Chicago. Their adventure brings joy to Cameron, as he laughs and enjoys himself at various Chicago landmarks, such as Wrigley Field. As he goes along with Ferris on their adventure, Cameron slowly realizes that there are wonderful things to be done in life. The progression of Cameron’s demeanor conveys the message of Ferris Bueller’s Day Off, as he learns to just take a…

Electrical Properties AC Conductivity, Ac Resistivity, Dielectric loss, and Dielectric constant are electrical properties and measured as a function of frequency. AC Conductivity and Resistivity AC resistance (ρac) was recorded by LCR meter model 4275 in the frequency range 1MHz to 3GHz. AC conductivity was determined by using the value of Ac resistance. As we know, Ac Conductivity is reciprocal of Ac resistance can be calculated by the relation; ac =1/ρac (6) The variation of AC…

magnitude in the disk(s) and ultimately lowers the area of operating hysteresis loop. Furthermore, for a thick disk, the radial component of flux cannot be disregarded in comparison with its circumferential component. In fact, such a two-dimensional field distribution will affect the overall performance of the motor. Also, It is clear from Fig. 6 8 that motors with thick disk require higher terminal voltage to produce a given…

To gather information about mechanical engineering, I interviewed Graham Jessup, a graduate from the University of Washington and a mechanical engineer at Electroimpact Engineering; a company based in Mukilteo Washington. Electroimpact is a world leader in design and manufacturing of aerospace tooling and automation. During the interview that took place through several emails, I learned much about what mechanical engineers are required to know, and how they use that knowledge to fully accomplish…

Shell oil began functioning out of Nigeria in 1937 under the name Shell D’Arcy. Upon discovering the first commercial oil field in 1956 in the Niger Delta, Shell Nigeria began exporting oil in the year of 1958 and has been doing so ever since. At one time, oil exportation was seen as a way to transition from relying solely on the agriculture industry for exportation and move into what was thought to be the booming economy of oil. The locals of the Niger Delta area have experienced little to no…

Main motives to be present in South-East Asia The Company Shell was created because its founder Mister Zijiker found oil in South-East Asia (Sumatra) in 1883 and since then Shell is active in getting petroleum and natural gas from this region. Due to technological innovations in the industry, the political developments in these countries surrounding Southeast Asia and the arising of Japan as a hotspot for petroleum trade operations led that nowadays Southeast Asia has become the most active area…

Electricity wasn’t invented it is already occurred in the nature. It was just discovered by Benjamin Franklin. His experiments (famous kite experiment) helped in building the connection between the electricity and lightning. In his experiment with kite included a kite with the key tie to the end of kite, which is connected to the Leyden jar. When the lighting struck the kite, the electric current travel down the string through the key and into the Leyden jar. We wonder that “what is there in…

electrical motors are made up of a stationary field referred to a stator and a rotating field referred to a rotor. According to Krishnan, (2010), DC motors operate through the interaction of an electric current with magnetic flux to generate a torque and rotational speed. D.C motors are of different types but they all operate…

Through the course of this assignment transcribing and interpreting Dorothy’s diary, there was a great amount of information to be gleaned about her life. While some aspects of Dorothy’s life, such as specific details about herself, are lacking, she provides plenty of evidence from which to draw conclusions about her employment, location, age, activities she does for fun, how she travels around, and the people she teaches and with which she works, shops, and goes out. To begin, it is clear…

magnetic fields. This struck great interest and lead to further research. In the 1830’s, an English scientist named Michel Faraday was credited with the discovery of induced currents and the practical behind it. He first wrapped a copper wire around an iron ring. On one side of the ring, there was a battery with a switch. On the opposite side, there was a galvanometer. He noticed a strange pattern in variations in currents. This evolved into further experimentation with magnetic fields. He…
