...Jonathan Frost 1-8-14 Single Phase AC Motors Single phase AC motors are a type of motor that is what the name implies which is one phase. In a single phase AC motors, a single phase motor has voltage and it splits into two phase currents to create a rotating magnetic field to generate the rotor. There are four different types of single phase AC motors and they are called split phase, capacitor, shaded pole, and repulsion. Capacitor and shaded pole is the most common motors they have. A capacitor run motor is connected between a main and auxiliary winding to create a phase shift in between the windings and a rotating flux. Split phase has main and auxiliary winding a centrifugal switch open and remove the auxiliary winding. It reverses at low speed, relatively cheap cost, and it has rapid acceleration. A single coil of a single phase motor doesn’t produce a rotating magnetic field, but a pulsating field could reach maximum intensity at 0 degrees and 180 degrees electrical. A single phase current and can produce two counter rotating magnetic field phases. Permanent-split capacitor motor have one way to solve a single phase problem is to build a 2- phase motor. It requires a motor with 2 windings spaces away 90 degrees electrical and displace two phases of current with 90 degrees in time. Permanent – split capacitor motor has increased current magnitude and also has a backwards time shift as the motor generates the speed pace. The motor works well...

...Big as it is, Canepa Design is easy to miss. The discreet boxy building sits just off a busy street in the quiet northern California town of Scotts Valley, just up the winding highway from Santa Cruz. But for car lovers, this place beams like St. Peter’s, an inviting treasure chest stuffed with classic automobiles worthy of pilgrimage. Vintage racing Porsches rub sheetmetal shoulders with iconic ‘60s Ferraris, which sit mere wheel-wells away from the last Shelby Cobra to exit the factory gates. Some vehicles are being restored for their wealthy owners, others are being spiffed up to hit Canepa Design’s showroom, while a few enjoy some mechanical pampering before being returned to their places of honor upstairs in the on-site motorsports museum. “I never get tired of coming to work,” says Bruce Canepa, the racing driver who since 1980 — the heyday of his professional exploits behind the wheel of all manner of Porsche beasts — has quietly turned Canepa Design into one of the foremost auto restoration and classic car sales shops in the nation. “Besides, I’m too obsessed with being in control of all the details to stop coming in.” Obsession and control can be a dangerous cocktail. But not in Canepa’s case. His hands-on personality means the cars coming out of this 70,000-square-foot shop often exceed the exacting standards of his monied clientele. When Canepa leans over the exposed engine bay of the aforementioned 1967 Cobra 427, he points out that “everything on this car...

...This experiment was to determine the amount of Red 40 present in M&M, Skittle and Mike and Ike using the spectrophotometer to determine the wavelength and absorbency. Red 40, also known as Allura Red AC or E129, is a red dye that may cause serious health issues and is also linked to ADHD in children. Based on the article by Vinita Sharma and others “Artificial food colorants are commonly used around the word to enhance the appearance of food.” The stock solution was prepared using 0.168 g/8 L Red Dye 40 the diluted to generate a five-point standard curve for absorbance at 500 nm. A total of nine candies were use three of each type and weighted and recorded. Candies were diluted in 10 ml of distilled water, filter and then poured in 100 ml flask. Distilled water was added to make 100ml solution then a sample was placed in the spectrophotometer for analysis. Figure 1. Plot of Red 40 The mass of Red 40 was 496.42 g /mol. The concentration was calculated to be 4.23*10-5 M. Table 1. Candy Data. Based on the data collected the amount of Red 40 present in red M&M and red Skittle was close to that of the 25% solution created from the stock solution. This amount is a significant amount seen that it is present in all red M&M and Skittle. Even though the Mike and Ike was an orange candy it had a small amount of Red 40 within it. Certainly, Red 40 is present in red M&M, red Skittle, Mike & Ike and also possible in other red or orange candies. This amount...

...Chapter 01 1.1 Introduction: A storage device may be used to store energy from renewable energy source in DC form which can be converted to AC power by using power inverter. Pulse Width Modulated (PWM) technique may be used to control output rms voltage of the inverter. As the load is variable, the power consumed by the load (PL) may be smaller than the power generated from the renewable energy source (PR). Therefore a Flexible AC Transmission System (FACTS) Controller may be used to supply the additional power (PR – PL) from the renewable energy source to the grid. On the other hand if the power consumed by the load (PL) is greater than the power generated from the renewable energy source (PR) therefore the same FACTS controller may be used to absorb the additional power (PR – PL) from the grid to the load. In this case the FACTS controller must allow bi-directional power flow. If all the active houses are connected to the grid in the same way (proposed way), the active houses that generate more power than the load can be supplied to the active houses that generate less power than the load. Therefore a suitable FACTS controller should be designed in such a way that it can control the power flow in both directions. The idea is illustrated in the following figure. 1.2 Objectives: • Study on different FACTS controllers • Study on different renewable energy sources • Study on different...

...an organization is thinking of implementing a New It Initiative they must ensure that they are well organized and fully understand the length and time a project may take. According to Cook “ Project failure occurs when a project is significantly over budget, takes must longer than estimated timeline, or has to be terminated because of so many problems have occurred that proceeding is no longer judged to be viable.” With Memorial Health System failed implementation of a CPOE system they had many problems including an over budgeted project, Lack of belief in project, Insufficient leadership support, Failure to respect uncertainty, Failure to anticipate short-term disruptions, and initiative undernourishment. In this paper we will discuss all six of these problems along with give possible solutions to each of them. Failure to respect uncertainty: When the system was finally implemented it was had a lot of bugs in the system. They implemented the system at all of facilities. Because of this as well as a few other issues such as lack of training the system was taken offline and they continued with the old system. The solution to this problem would have been to implement the system in one location instead of the entire hospital. This place can be used as the test facility in which you can do two things. One you can work all the bugs out and the other would be to use it as a training facility where you can send employees to get training on a system that is up and running. This will...

...SUMMARY Recently there is something wrong with the performance of our company and I think what we should do is to upgrade the office furnitures. Because more and more of our employees claimed about the poor working condition. We can reduce the surgery fee and the sick days from the employees after the upgrade. Therefore, we can increase our productivities a lot. THE PROBLEM 1 Increase health problem- More of our employees are having health problems because of the uncomfortable furnitures. 2 Sick days increase-Because of their health problem, employees asked for the extra vacation day. 3 Surgery fee increased- Three employees had to have carpal tunnel surgery, and another had back surgery 4 Insurance fee increase- The insurance carrier was threatening to raise its premiums. 4 Productivities reduce- The day-to-day productivity of the office reduced THE REASON The problem came up from last year. If we don’t care about the problem, it will cost us a lot. For example , we already have three employees need to do carpal tunnel surgery . Cost of surgery and rehabilitation is in the range of $5,000 to $10,000 (data from :http://www.mycarpaltunnel.com/surgery-release-carpal-tunnel.shtml).And we have one employee need to have back surgery. According to the data from www.ehow.com. This procedure costs an average of $12,000to$15,000. So far the maximum cost is approximately $45000. And if we ignore that, the number of employees who need surgery would double in the next...

...Buenavista Plywood Corporation The Problem The problem confronting Mr. Antonio Garcia, the Plant Superintendent of Buenavista Plywood Corporation is how to deal with the absentee rates of the employees from Bohol such that the production of the plant will operate at capacity, with adequate workforce and the interests of the company and employees be served. Objectives More specifically, the problem resolves itself into the following objectives which Mr. Garcia has to achieve in the course of action he has to take: 1. To maintain a stable and reliable workforce; 2. To protect the company’s reputation by avoiding confrontation with formal union groups; 3. To address production problems and costs; 4. To meet the rated capacity of the plant; 5. To safeguard the long-run profitability and stability of Buenavista Plywood Corporation. Situational Analysis The Buenavista Plywood Corporation was organized in Cagayan de Oro City in 1950 by the Santiago Family. Don Jose Santiago, the present head of the family, was well qualified to carry the traditions of this prominent family. The Santiagos have been involved in politics in nearby Bohol, the ancestral home. They had been pioneering industrialists in the plywood business. Don Jose had been an early advocate of local processing of lumber as opposed to the shipping of log abroad. VISTAWOOD, the trademark chosen for their plywood, was one of the first export plywood production in the Philippines. Late in the...

...to discuss the staff management problem Arthur Reed faces every summer. Arthur Reed, a supervisor at the Blue Grocery Stores, has an issue with hiring temporary workers in sufficient numbers to cover the sick and vacationing workers for the summer months. As warehouse supervisor in charge of two shifts on the shipping dock, Arthur usually manages to run the shifts smoothly every year except in the summer months. During the summer months, Arthur faces a shortage of staff when most of his senior staff call in sick or take vacation. Arthur runs into this problem every summer and does not look forward to the frustration of trying to hire sufficient temporary workers this summer. Although Arthur has earned the respect within the industry and has 20 years experience in the grocery industry, when it comes to dealing with staff shortage, Arthur does not know how to manage the problem. If Arthur knows he will faces this problem yearly, then why does he not plan ahead to avoid the frustration? Perhaps Arthur is not managing his staff as well as he can because he is lacking in supervisory skills; otherwise, he would not have run into this problem every summer. What are the problems? Staff management and on-call workers are the problems. In my opinion, Arthur is having a problem managing his senior staff because he is not communicating with them effectively regarding scheduling vacation and call-in sick days. The reason he keeps having the same problem every summer is that there are no...

...there for learning but they want to network with other people within the class. They are looking to make connections in order to have more connections for a later date, maybe for a better job or for something they may need in their current company. The vacationer mindset person is there to get away from everything not to learn. They want to get away from the office and enjoy their time away. The prisoner feels as if they were forced to be there and they come in mostly with a closed mind about the training they are attending. Rosner also speaks about some problems that people have within their organizations and how some of these problems are misdiagnosed because the proper people are not in the proper positions with the proper training. Rosner quotes from Valerie Oberfie, a former vice president at Disney University that has done business consulting and training for corporations. She says that to avoid misdiagnosing a problem businesses should do their homework (Rosner, 2009)....
