The history of piezoelectricity evolution is over 120 years which was discovered by brothers Curie in 1880. They were Pierre Curie (1859-1906) and Jacques Curie (1855-1941). During the study of the generation surface electrical charge by applying pressure on some material, they found out an unusual phenomenon which was a voltage of opposite polarity was generated by pressure was applied on the crystalline minerals such as quartz. The amplitude of the generated voltage was proportional to the…

"A philosophy of architectural design, emerging in the early 20th cent., asserting that in structure and appearance a building should be based on organic forms and should harmonize with its natural environment." — Dictionary of Architecture and Construction Organic Architecture is a style that aims to be in unison with the environment. It strives to be in harmony with nature; not dominate and destroy it. This architectural style seeks to blend in with its environment, to appear as if the house…

carries a bunch of sensors to observe the direction of vehicle and other parameters. The lightening system is smart enough with LED lights to bend the projection towards the direction of vehicle's move and adds visibility to the blind turns. The ceramic composite brakes at both the ends of the car endows optimum braking distance with their 6 piston caliper at the front and 4 piston caliper at the rear. The whole chassis is made of aluminium and magnesium with inserts of high tensile steel at the…

In other words, all the search processes provide all the solutions for the problems, so that the hardness of ceramic Al2O3–TiC–TiN samples either increases or decreases. The best search which leads to the best solution (the best food source), represents the best optimized values for the process parameters. Depending on the local or visual information, an employed…

I believe that the meaning of the word art is an expression of feelings or ideas through different mediums. Throughout history I don't believe that this definition has changed but the different mediums have. As society has grown, we humans have modified our way of expressing our feelings through our advanced technology. The influence that I had that helped me discover this definition was my experiences through my art classes. As I produced many different art projects I felt that these different…

In body armor, layers of Kevlar are used to slow down a bullet and break it down. These layers of Kevlar slow the bullet down enough so that it is stopped by the ceramic plate on the inside of the vest. Kevlar is also used in drum heads. The Kevlar is tightened to a high tension to create a cutting sound that pierces through the marching band. Many other materials like Mylar, aren't capable of being stretched like…

Introduction The monumental Middle Bronze Age gate, complete with two well-preserved mudbrick towers, represents one of the crowning architectural achievements of Canaanite Gezer. The gate, the defensive wall, the grand watchtower, the row of standing stones, and the massive rock-hewn water system illustrate a flourishing MB II society at Gezer. While Irish archaeologist R.A.S. Macalister uncovered all these features in the early 1900s, archaeological and anthropological questions remain.…

court. Egyptian temples were closed in 392 A.D. by rule of the Byzantine emperor. The last known hieroglyphic engraving, from Philae, dated to 394 A.D. The arts in all expressions, such as stone and wood sculpture, carved ivories, painted glass, ceramics, and textiles, were adorned with atheistic and Christian themes that showed the cultural diversity of the age. Egypt's dry temperature, added with the new practice of burying the dead in their clothes, also wrapped in their shawls and hangings.…

The car is a vehicle that is driven by army personnel wheeled machines, four or more (always even), usually using a fuel (gasoline or diesel) to turn on the engine. The car is short for "automobile that comes from the Greece ' autos ' (himself) and Latin ' movére ' (to move). There are about 250 million cars in the United States at this time. Worldwide, it is estimated there are 806 million units of cars and light trucks in 2007; burn more than 260 billion US gallons (1 gallon = 3.8 litres)…

Blow out II Going to the art gallery Blowout was my first time going to an art gallery in a very long time. I have never really been around art. The only art I have been exposed to has been through art class in middle school and high school. I found art class fun but art has never really stuck with me, I was never really good at it and that frustrated me. When I was assigned to go to the art gallery I was excited to see the art and be and try to become more familiar with art, with that…
