work presents a variable speed control techniques for single phase ac motor. A pulse-width-modulation (PWM) AC chopper changes the value of the supply voltage applied to a single-phase motor. The variable supply voltage gives better speed control of motor. Harmonics generated by unit of speed control are filtered by an input filter circuit. Experimental results would be in 230V and speed control of single-phase motor shows that PWM AC Chopper is simple and cost effective control method compared to better

Though, the EIR does not provide a number for Car ownership rate, they do provide an approximation of the mode share at a.m. and p.m. peak hours; the data further reinforce the idea that the Plan Area must have a high rate of car ownership. In the Table IV.D-3, the mode share is illustrated as, “Person trips with auto, transit, and others[non-motorized modes such as walking and bicycling] on a weekday basis.” Under the existing condition plus plan, auto has about, “39.6% out of 21,240 persons during

performance of the UPFC to control voltage in disturbed power systems. Index Terms — Facts, UPFC, Power Systems, disturbances, Interface, Modeling, Controls. I. INTRODUCTION The term ”FACTS” (Flexible AC Transmission Systems) covers several power electronics based systems used for AC power transmission and distribution. The most interesting for transmission

You Are What You Eat Do you read the labels on the products you buy? Do you know what is put in the food you consume? There are many health risks associated with the additives in products. Most Americans are unaware of the risks that are linked with the additives in commonly purchased products. My daughter was one year old when I realized she was allergic to artificial coloring. One morning we woke up and I made us a toasty bagel. I topped the warm crunchy bagel with light pink, strawberry, cream

The very first artificial dye was created by accident in 1856 by William Perkin9. Perkin’s dye chemistry set the stage for pharmaceuticals, plastics, etc. These products were not intended to be used for consumption, yet we eat them daily and use them in numerous other products, such as supplements, medicines, mouthwash, shampoo, and hand sanitizers (Gavigan, 2013). Gavigan’s general claim in the article is that petroleum based dyes are not safe. He goes on to also claim that “FD&C Red No. 40 may

“Batman” She shouted “What?” “I finally figured it out I’m going to call you.” She said with the biggest grin on her face. “You are my dark knight so batman is the only name that fits” From that day on everyone started calling me batman. People create nicknames based upon their own needs. Some need a new insult others need a change, a fresh start. All must encounter the same problem at some point in time. What does this nickname really mean and when does it begin to take your place in life. I had

Comic books, in todays rise of all that is geek it is hard to avoid hearing about the next comic that is being adapted into a movie or TV show. With films like The Avengers and The Dark Knight and shows like The Walking Dead comic book based properties are taking over most of pop culture today. Yet, despite all the attention on these properties there is still an overwhelmingly popular misconception that comics are “kids stuff.” Yet, unbeknownst to the overall public in western society comics are

Alan Moore and Dave Gibbons’ Watchmen illustrates the lives of retired superheroes in the 1980s. The Keene Act outlawed the “masquerading” of superheroes in the 1970s and led to the dissolution of many superheroes. The murder of an old colleague, The Comedian, forces them to come out of retirement and sets the events of the graphic novel into place. Moore and Gibbons sets up a world of superheroes in the midst of a very real historical period of the Cold War. We usually think of superheroes as existing

History of American Comic Book Superheroes. Before they become significant box-office phenomena and debut for TV serious, superheroes were short stories in printed media. Supermen, Batman, Captain America, Wonder Woman …were comic books superheroes. The idea of superheroes was long existed. However, as many comic books historians agreed, The Phantom, published in February 17, 1936, is considered to be the first comic book costumed hero. Since then, comic books superheroes were booming. In the mid-1940s

When defining great literature, graphic novels are often the last source scholars and educators consider. In general, graphic novels are seen as low-brow, mass culture entertainment or as pedagogical tools (Long 6). In recent years graphic novels have proven to be worthy of being considered great literature and valuable tools in the classroom. Comic books should not be viewed simply as aesthetic objects, but rather as texts which function when read by their audience within a specific context. Our
