ABSTRACT

My experiences:

With the completion of this training, I am now aware of the Microcontroller 8051. I have worked for six complete weeks in the Embedded systems. I have worked almost as an engineer to the extent of my technical capabilities. Doing all these, I have acquired a lot of knowledge about the working of Microcontroller with Embedded C Programming and its Softwares (Keil u vision).
I was the part of one of the most happening and demanding field of electronics i.e. 8051 Microcontroller started byand spending six weeks into it really proved very useful to me and I have gained a lot out of it : 1 I got the knowledge of uC 8051 (Harward Architecture & Cisc type). 1 I worked practically on the softwares Keil u vision. 1 I worked practically which helped me in being more familiar to the interfacing of different display devices which I am supposed to do in the long run. 1 I learned basic concepts of electronics which helped me to understand more. 1 Training helped me increasing my working skills and the knowledge in this field and also showed me the atmosphere that we have to join after completion of the degree program.

Finally, the main advantage of this training was that it has now enabled me to explore myself in the giant software industry.

...to which there are four phases a product goes through during its life. They are named as introduction, growth, maturity, and decline stages. In first stage of a product, the company normally does not earn profits. Since after the introduction, it takes a certain time for the people to know about the product. It is, however, dependent on the suitability of the way with which the company markets the product. The second stage is growth during which the product becomes pretty much popular, so more and more people tend to purchase it. During the third stage the revenue generated by the product reaches its culmination point. Beyond this point you may find the product demand gradually declining towards its end. Likewise, iPod touch is now viewed as in its final stage of product life cycle. Although, the company has taken a step by redesigning it but the sales are yet expected to be limited. One of the most reasonable suggestions for the company is to improve the product by adding more features. This will increase the possibility for the product to survive in the market. One of the most popular products of Apple Inc. is I Phone. People are crazy about it due to the good quality and strong brand image. However, in view of many analysts, the sales of I Phone have reached its culmination point.

Neuroprosthetics

...electrical, and mechanical engineering, including such areas as electronic control systems, communications, imaging, sensors, biocompatibility, and biomaterials, as well as the university's growing capabilities in bioMEMS (Bio-Micro-Electro-Mechanical Systems). Luke Skywalker’s Hand and How Touch is Like Vision Perhaps the most famous neuroprosthetic device in movie history shows up at the end of The Empire Strikes Back. In the final scene, Luke Skywalker is fitted for a new, robotic hand to replace the one so cruelly lopped off by (spoiler alert!) his father’s lightsaber. To test out the new hand, Luke first flexes it a couple of times, then allows a droid to poke it in several places with a thin needle. That latter part is actually an important test, verifying the sensory ability of the prosthetic to mimic a real hand’s response to pain or pressure. Last week, we wrote about BrainGate, a neuroprosthetic that allowed some quadriplegic subjects to control a robotic arm with their brain activity. But a successful prosthetic limb, whether for a quadriplegic or an amputee, would need to have not just motor control, but also some semblance of sensory feedback replicating the ability to touch and sense the limb’s position in space. Imagine if you could move your hand but couldn’t feel it – tasks such as picking up a coffee cup without looking, catching a ball tossed your way, or removing your hand from a hot stove would...

We will do this by showing companies how they can gain an advantage over competition that hasn’t yet began offering this service to their customers. At this point we want to show our customers how Quick Touch benefits their organization and how it will benefit their customers. Quick Touch systems will help companies keep up with consumer demands and the technology boom. We plan on targeting the fast food industry but would like to quickly move into new territory like theme parks and retail stores. As Quick Touch enters into stage three, market maturity, we will likely see many other products on the market that are similar to ours. During this time we will focus on reminding current customers what our systems can do for them and the reliability we offer, we will begin updating our technology and looking at ways to enhance our products. During this time we are also likely to begin rolling out newer model kiosks and products that can be offered at a discount to loyal customers. This would also be the best time for Quick Touch to begin price matching or looking to beat our competition where it comes to pricing and begin offering competitive package deals and service plans to try and remain a step ahead of the competition. During the forth and final stage of Quick Touch’s life we are likely to see some customer...

Critic of 'After Death'

...death. The irony is that the man did not love she in life, but, instead, pitied her in death. This essay will examine two main elements that are used in “After Death” depicting the relationship missing and the child’s observation of the continuing absence of affection. First, Rossetti does not address the gender of the child, however, a feminine presence is felt with her description of the man and child’s relationship; both the physical and emotional aspects of the poem paint a father, daughter connection. The second is examining how “After Death” uses four out of the five senses to take us through the poem. The poem brings the reader on a journey beginning with smell and sight, then leans toward sound, and concludes with a cold touch. The senses show the absence of love between the man and the child, not by what he does, but by what she notices he does not. “After Death” has only two characters, a man and a child. The gender of the child is never mention, but the reader can understand that it is meant to be interpreted as a young girl, the man’s daughter. Although the poem is short, Rossetti is able to make it evident in multiple lines. “He leaned above me…” from line five is to show an authority figure coming from above. In the Victorian age, women were very limited and men were their authority figure; Rossetti tapped into the era’s...

Patriotism By Janice Mishima

...In 'Patriotism' Mishima developed the theme of loss through the use of the intense sexual imagery in contrast. In Mishima’s word pictures, both lieutenant and Reiko’s bodies were glowing with the glitter of life. However, in the contrary, what they had possessed led to the opposite side: death. Mishima intended to present the extremely beautiful flame of human’s life at the mercy of the dust of death. Yet how gorgeous fireworks are, they shine briefly. Obviously, Mishima understood it and used it as a sigh for the loss of human’s power, the burning fire of life. Enveloped by the shadow of death at their last touch, lieutenant and Reiko showed their desire for each other and their delight of passion, but undeniably, they were forced to...

A pseudo-code statement representing sequence would typically contain text very similar to what is found within the rectangle of the flowchart. The sequence control structure simply lists the lines of pseudo-code. The concern is not with the sequence category but with selection and two of the iteration control structures.

Levis

...Levi’s Strauss was the market leader for women’s jeans in 1995. However its position as leader was coming under heavy attack. Focusing on size combination (which they offer 51), Levi’s was losing ground as more styles, more colors, and better fit became more important to its customers. Market research showed that only 24% of women were completely satisfied with their jeans purchase, at $50 a pair they were becoming a tough sell. Levi’s responded by recognizing a need to be in closer touch with their customers. They began to open stores to sell directly to their customers (rather then trough another retailer). They also implemented new technology such as EDI to help their supply chain. Unfortunately the lag time for their products was still 8 months.           Levi’s was a company that needed a way to strengthen their business. Using the value chain analysis Levi’s was a prime textbook case of a company that needed to improve its value chain in order to sustain a competitive advantage. The results of their value chain analysis are as follows: 1. Value: only 24% satisfaction rate. 2.  Value stream: ROE average more then 38% lead to little improvement in their cumbersome value chain. 3.  Continuous flow: 8 month lag time. 4.  Pull: The customer initiated nothing, activity was driven by sales forecasts. 5.  Perfection: A good ROE led management to miss opportunities in improvement. In addition, use a pull driven distribution strategy Levi’s lost big profits when retailers had...

Sport

...Development of Football in England The idea of football came from the medieval game that was known as mob football which included two villages that would play with a pigs head. The game had no rules which meant that violence was a large part of the game and they would play until people were dying or until people were running away. Balls were not invented so the people would use a pigs head and kick that around. King Edward II was the person to ban the game as it created too much violence within the people of the country. 1581 is the earliest account of football as an organised sport. It was played between elite schools such as Eton and colleges such as Cambridge and Oxford. Sides, positions, referees were introduced. The game was played on just and average field like what farm animals would be on and they would use the gates as a goal. 1848 – Cambridge Rules This club shall be called the University Foot Ball Club. At the commencement of the play, the ball shall be kicked off from the middle of the ground: after every goal there shall be a kick-off in the same way. After a goal, the losing side shall kick off; the sides changing goals, unless a previous arrangement be made to the contrary. The ball is out when it has passed the line of the flag-posts on either side of the ground, in which case it shall be thrown in straight. The ball is behind when it has passed the goal on either side of it. When the ball is behind it shall be brought forward at the place where it left...

Fencing

...Fencing Fencing, as cited in the Webster's Dictionary, is "the sport of fighting with swords, esp. foils, épées, or sabers, according to a set of rules, in order to score points against an opponent." Fencing is very popular in the European culture. Many people refer to it as "Sword Fighting" it is seen in many movies, as well as books. In the sport, the two opponents are required to wear a specialized uniform to protect themselves when waving the foil, épées, or saber, around. Fencing is defined as "The sport and act of swordplay." The history of fencing as changed extensively over the years, before the Christian era, almost two thousand years ago, they used spears instead of the known weapons used today. Once the invention of gunpowder came into play, it changed to a fight to the death by many nobility to restore and avenge honor. As they entered the fourteenth century, Germany was the first country to try to legalize fencing as a sport, as well as fights to the death, this did not go over very well with everyone. During the fifteenth century Spain decided to establish the first fencing school. Soon after that, the eighteenth century grew the idolizing sport, but many countries in Europe decided to get rid of the fight to the death factor of the sport, as well as added protective covering to those that played the sport, to insure the safety of opponents. Around this time, Italy, France, and Germany, decided that the sport was better played with specialized weapons, hence...

Mystery Egg

... Teacher Love at the lips was touch As sweet as I could bear; And once that seemed too much; I lived on air That crossed me from sweet things, The flow of - was it musk From hidden grapevine springs Down hill at dusk? I had the swirl and ache From sprays of honeysuckle That when they're gathered shake Dew on the knuckle. I craved strong sweets, but those Seemed strong when I was young; The petal of the rose It was that stung. Now no joy but lacks salt That is not dashed with pain And weariness and fault; I crave the stain Of tears, the after mark Of almost too much love, The sweet of bitter bark And burning clove. When stiff and sore and scarred I take away my hand From leaning on it hard In grass and sand, The hurt is not enough: I long for weight and strength To feel the earth as rough To all my length. “To Earthward” by Robert Frost exemplifies the concept of how attraction and love change over the years from youth to bitter love to a love that craves relief from the pain of life. Frost begins the poem’s first stanza with the lines “Love at the lips was touch/As sweet as I could bear”.  With this opening phrase Frost shows that youthful love is consumed...
