Transmission of Wireless Message based on Embedded System

Transmission of Wireless Message based on Embedded System Transmission of Wireless Message based on Embedded System with Robotic Arm INTRODUCTION: 2.1) This career episode describes the project Transmission of Wireless Message based on Embedded System with Robotic Arm. I started off this project under the guidance of my assistant professor and with a team of two engineers including myself, during the last three months (October 2012-December 2012) of 7th semester while pursuing Bachelors of Engineering (Electronics and Communication) from Gujarat Technological University, India. The assigned duration for the project was three months and with the help of my professor, we were able to complete each task of the project on time. This project was implemented as a part of my academic curriculum Wireless Communication. For this project, I was working as an Electronic Engineer. BACKGROUND: 2.2) In this universe of learning and understanding all the things that are nearby, is controlled through machines, having the ability to compute. This specialized excellence and integration in various departments can prompt an exceptional alteration in everyones lives particularly interchanges department. Because of different alterations in innovations, numerous frameworks are made with stunning advancements. The most innovative one is the Embedded Systems. Embedded system is the advancement or further improvement of computer science framework. Its application give colossal chances to innovative utilization of PC innovation. Verging on each new framework presented in the business sector is a case of Embedded System. 2.3) The framework which we have created is a utilization of an Embedded System. At first, we began off with the manner of thinking of building up a wireless message roundabout model which could help both establishments and in addition enterprises. A further research into the framework prompted the possibility that equivalent framework can act like a concentrated framework for ambitions, for example, managing, observing plus correspondence keeping aside human intercession. 2.4) Project Objective To describe in few sentences, my projects main deliverable was to send the data from one place to another place through transmitter and receiver using RF technology. The microcontroller works as brain of the unit. Microcontroller controls the functions of the LCD, conveyor belt motors, and vertical/horizontal motor track motor in order to perform desired action/task using robotic arm (mechanical hand). 2.5) My roles and responsibilities included: Selection of electric components Simulation of Motors, LED and LCD using Proteus Programming of ATMEGA16 microcontroller using BASCOM software. Assist in constructing mechanical hand and conveyor belt Schedule weekly meetings to discuss goals and achievements Assist in maintaining documentation. 2.6) Project mechanism PERSONAL ENGINEERING ACTIVITY 2.7) Training We decided to go for training first since it really helped us to move forward without a hurdle in my work. It is required for the beginners to undergo a training session in order to acquire knowledge and develop skills at an industry level. This also helped me to understand the difference of work culture between industry and college level.ÂÂ   In the practice session under the guidance of my professor, initially we discussed the design process of the project and different components to be used on the transmitter and receiver side such as microcontroller, USB to UART convertor, encoder, and sensors. I also learnt the software Proteus and BASCOM for the simulation of motors, LED, LCD and programming the microcontroller. Furthermore, safety training sessions were also given to build mechanical hand and designing circuit in the safest way possible. Before the implementation of any task, we were given proper safety measures. 2.8) Software Before starting the hardware implementation, I decided to learn the software Proteus. Proteus is an open source software used for simulation of electric circuit and has the ability co- simulate and interact with software running in the microcontroller. I learnt this software by referring tutorial videos and simulating sample electric circuits. In this project, I used Proteus for the simulation of motors, UART, LED and LCD. Furthermore, I also used the software named BASCOM. BASCOM AVR is an intense and simple to-use compiler for the AVR arrangement of smaller scale controllers created by Atmel. It took me hardly any time to master this software since it was very easy. The system accompanies an extremely easy to use interface and an arrangement of straightforward summons, and gives more adaptability than different projects in this classification. Anyone with some fundamental learning of C or C++ can compose a fruitful system utilizing BASCOM, as the majority of its capacities and its announcement structure is like those in C. 2.9) Hardware implementation After training, I started my research to select the most appropriate components for hardware implementation refereeing and comparing datasheets of each component. Keeping in mind the guidelines of designing a circuit, on the transmitter side included computer, usb to serial converter, microcontroller, encoder and transmitting module. Whereas on the receiver side, I used receiving module, microcontroller, LCD display, IR and metal sensors. For the conveyor belt, we used two DC motors to pass an object on the belt. In this project, we also introduced a robotic arm (mechanical hand) as an application which can reduce the human efforts and controlling can be done effectively. There were some difficulties which we faced while constructing the mechanical hand i.e. we built the arm using two DC motors but while using it, we realized that it delivers low torque. Therefore, we discussed this issue with our professor and we came up the solution to build the arm using a combination of BO and DC motor. We designed this mechanical hand at very low cost which is very efficient and can be used in many production industries for packaging or assembling goods which mitigates physical labor, consumes less time and reduces risks as well.ÂÂ   The mechanical hand in this project was used to pick an object from the conveyor belt and put it to a required place as per the application. ÂÂ   Conveyor BeltRobotic Arm ÂÂ   Transmitter SectionReceiver Section 2.10) Pseudo flow of the system: Input is provided via Computer which is converted in to serial using UART. The serial data is sent to the microcontroller which is then encoded using encoder and transmitted via RF through transmitting antenna. Receiving module receives the message and passes it to the microcontroller. Microcontroller starts processing the program implemented on it. This leads the motor drive to provide high signal current to the motors which drives the conveyor belt and mechanical hand motors. If there is a metal/object detected on the receiver side of the conveyer belt using metal/IR sensor. The conveyor belt stops and the robotic arm performs its action depending upon the programming implemented on the microcontroller i.e. picks up the object and puts it at a required place as per the coding implemented in the ATMEGA16 microcontroller. SUMMARY: 2.11) This project was to give the ways for providing bigger effective mechanical hand for industrial applications. The achievement of this hand is to demonstrate that reliable grasping can be achieved with inexpensive mechanism and IR sensors. This hand can grasp variety of objects with different surface properties and sizes, having no need to rebuild a surface description of the object. Overall, the journey of the project was very productive, learnt new skills and enhanced acquired skills. We submitted our project with final documentation and a presentation with the prototype to our head of department and tutor. Although we faced many difficulties during this project but we never gave up. The toughest part was to build the mechanical hand and time constraint but working with a team made this project successful.

Antonio Macéo :: Antonio Maceo Biography Bio

Antonio Macà ©o: The Bronze Titan The people of Cuba had many great heroes during the Cuban War of Independence. One of these heroes, Antonio Macà ©o, contributed strength and bravery as well as leadership and patriotism. Born June 14, 1845, Antonio de la Caridad Macà ©o y Grajales was raised by his French father and Dominican mother in Santiago, Cuba. His family migrated to Cuba from Venezuela, approximately twenty years before he was born. As a young boy, he was under the influence of his godfather, an educated attorney and active participant of the Masonic lodges, or the fomenters of dissent as they were known by the government. Although he lacked the conventional education attained by many other Cuban heroes, he attempted to educate himself under the guiding influence of his godfather. The Macà ©o family itself lived quite well in a house in town, as well as, the farmland they acquired. Throughout his adolescent years, Macà ©o worked as a product distributor for one of the family farms. Having to travel great distances, he learned to navigate the surrounding terrain which proved to be a great advantage in his later years as a freedom fighter. Outside of his tasks as a product distributor, Macà ©o roamed the fields with his adolescent companions, avoiding inane conversation to cover a slight stutter in speech. Growing up into a proper and upstanding man, he married his neighborhood sweetheart, Maria Cabrales. They had two children, both of whom died at an early age. Shortly after his marriage, Antonio Macà ©o joined the liberation army. He fought with his father and brothers in the Ten Years' War (1868-1878). His effective leadership enabled him to rise in command to the position of second leader. The army, however, endured several changes which would cause its eventual disintegration of power. Many members of this army felt they could accomplish more without the leader, Carlos Manuel de Cespedes. In 1878, at the end of the Ten Years' War, Antonio Macà ©o refused to cease the war with Spain due to the existence of slavery and the imperial power's continued subordination of the people of Cuba. He left for New York later that year only to return in 1895 for the War of Independence.

Essay on Social Order in The Tempest -- Tempest essays

The Social Order in The Tempest  Ã‚        Ã‚  Ã‚   In Shakespeare's time, the social order was as powerful and rigid as law. Shakespeare provides an example of this social structure in his play, The Tempest. In the course of his play, the reader sees superior men dominating lesser beings on the basis of race, financial status, and gender. Not all upper class are completely corrupt, however. We see a semi-virtuous hero in the character of Prospero. Prospero has every reason to feel superior and exercise his social power, yet he doesn't always treat others disrespectfully. Although he does have some sense of charity, Prospero is still a good example of the social condition of the time.      Ã‚  Ã‚  Ã‚   One way in which The Tempest reflects Shakespeare's society is through the relationship between characters, especially between Prospero and Caliban. Caliban is the former king of the island, and Prospero and his daughter Miranda teach him how to be "civilized." Immediately thereafter, Prospero and Miranda enslave Caliban and he is forced to be their servant. Caliban explains "Thou strok'st me and make much of me... ...otte Porter and Helen A. Clarke (eds.)

Psychological factors of tennis :: essays research papers

TASK ONE PART A FEEDBACK AND MOTIVATION OFFERED TO THE PLAYERS BY THE COACH TO IMPROVE SKILLS, COURT PLAY AND MENTAL ATTITUDE Stuartholme A Grade Tennis Team Dennis Sheard, (the coach of the A team) was mainly focusing this particular training session on footwork and communication as he felt that the team lacked both these factors during their previous Saturday match. The following are a few quotes from Dennis  "Awesome footwork Alex, could you feel the difference between that ball and the last?" Dennis indicates when the players use the correct technique and then compares it to a previous shot where they do not. This is enabling them to get used to using internal feedback independently and how they should be executing the shot.  "Correct technique, but you didn’t squeeze the grip again. The raquet shouldn’t wobble as you hit it." Dennis recognises the problem, explains it and then evaluates it for the player, making it clear what they did wrong and how they can improve it.  "If you’re partner gets a hard ball to reach I want to be able to hear you encouraging her to get it to it, I want to hear lots of "Go, go go’s!!"" Dennis stresses the importance of communication and encouragement in doubles. This communication increases motivation and a goal to reach for the players.  "I don’t want to see any slumped shoulders or negative expressions when you miss a ball, that’s the time you need to be even more confident and focused on getting the next point." Dennis reminds the girls constantly on staying positive and not losing their patience during their games as this can make them become over or under aroused. Psychological Stuartholme D6 Tennis Team The D6 coach Kate, was fairly quiet during their coaching session and when she did offer advice she would sometimes put it with a shot that didn’t necessarily match the comment, confusing the girls. This is a lower ranked team and the girls are still at quite a cognitive stage of developing their tennis skills, this means it is vital that they receive a lot of feedback and encouragement to persist with the sport. By not offering this Kate may be hindering their development. She did however put forward the following points to the girls.  "Good shot"  "Move your feet"  "Keep your eye on the ball"  "Swing slower" Although Kate is offering advice to her players in order for them to improve their skills she needs to be more specific so they can understand their mistakes and correct them.

To What Extent Does Cultural Background Influence Ones Perception of Human Beauty

To what extent does cultural background influence ones perception of human beauty? â€Å"Beauty is in the eye of the beholder. † This famous quote simply expresses the universal concept of beauty has no intrinsic or definite meaning. From this, one can derive that beauty can be nothing more than the subjective perception of human individuals-it is all based on ones predilection and proclivity. However, it is not just to say that anything can be considered as beautiful, thus contradiction does not exist in perceptions of beauty. As one can see, there are certain guidelines to beauty. Whether it is the inner or outer beauty of a human being, the concept of beauty that society imposes is all shaped from general consensus. Then perhaps â€Å"Beauty is not one’s own, but a reflection of one’s culture†. Even though nothing can be defined as absolute beauty, due to the limitation ones cultural backgrounds created from the subjective nature of perception, Human beings in the end will still unite their perception of beauty to a universal degree of understanding. The rift in the perception of physical beauty between cultures can be placed on two ends of a spectrum. In both Western and Eastern Culture’s ideology of beauty, having a slender body is crucial to be considered as an attractive woman. However, as we shift our view to the third world countries in Africa, this measure takes a drastic turn and becomes weak and meaningless. In those countries where poverty and diseases are the plays a key role, plumpness-being the sign of health, wealth and fertility is the ideal beauty of a woman. Moreover, a culture’s own tradition of beauty cannot be overlooked. Padaung women of the Kayan people wear a special ornament called neck rings around the neck of an individual to create a visual appearance of a stretched long neck. This tradition of elongating necks to achieve beauty is probably not accepted by others. Furthermore, the influential power of media cultural also alters ones perception. The concept of beauty in men displayed by the Japanese pop idols with distinctly feminine features is also one of the rare occurrences in perception. Despite the range of different perception of beauty presented in varies cultural, they are all collided to establish one fact-that is to be accepted but the general consensus within their culture. However, speaking of acceptance, all the rift between culture’s perception of physical beauty are stirred together to create the universal acceptance of the inner beauty of mind and heart. â€Å"Beauty is only skin deep. †The acceptance of inner beauty goes beyond the subjective norms of beauty that varies between the different cultures one is exposed to. Gibran had concluded that â€Å"beauty is not in the face; beauty is a light in the heart†. When it comes to these values of love, compassion and moral code, humans’ emotion, conscience and perception are unified to form a common knowledge. As described in Plato's Philebus, the measure of beauty was structured and related to intelligence. One understands what is to be considered as a lovable person not only by their outward appearance but by tying the strings of the inner quality that one possess as well. With this commonality, the barrier of subjective beauty is broken down. As one gives and receives love on a daily basis, following the universal idea of moral code and intelligence, their perception is broaden to a degree of understanding that the â€Å"Miss Universe† Pageant† can be hosted based on this commonality beyond cultural differences. Therefore, one can say that the universal acceptance and emotion unifies the human belief of a beautiful person. Although the universal concept of beauty has no definite meaning and can alters from one perceiver to another. It can also be viewed that â€Å"human beauty is a reflection cultural perception and ideas of aesthetics and indigenous to that area†, but one cannot deny that the there are certain values built upon a common understanding. With this common understanding, the rift of perception between different cultures becomes narrower thus in the end, allowing ones perception of true beauty to be united to a universal degree of understanding.

Capitalism and leisure

Capitalism depends on a continuous sense of dissatisfaction to exist.   The temporary relief experienced by dissatisfied workers engaging in leisure activities such as shopping is not caused by the acquisition of an object, but rather is produced through the action of conspicuous consumption of those objects.   In other words, the relief is felt during the pursuit of certain objects and the exchange of money for goods, but diminishes almost immediately once the desired object is obtained. IPods and MySpace are recent examples that seem to bear this out.   The acquisition of an IPod necessitates the pursuit of music and the desire to perpetually obtain more music, while MySpace consumes massive amounts of free time and functions by the constant acquisition of â€Å"friends†.   They cannot create satisfaction in their original state; they only create satisfaction through the promise of acquiring infinitely more. Leisure activities such as attending the movies, on the other hand, produce temporary satisfaction through the conspicuous consumption of personal time and diminishes shortly after the movie ends.   Marx and Singer are correct in their assertion that life in the modern era is essentially dissatisfying: the capitalist economy could not exist without a pervasive and perpetual sense of dissatisfaction. However, the assumption that workers who are not alienated from their labor are generally more satisfied seems to discount other concomitant factors, such as the spirituality and close personal and family relationships that both capitalism and communism discount as irrelevant or unnecessary to life in the modern era.   Both can be considered leisure activities, and both have been reported to produce levels of satisfaction among those who participate in these types of activities.

An Analysis of Brokeback Mountain Essay

Annie Proulx’s Brokeback Mountain is a tragic story of forbidden love. It chronicles the romance between Ennis Del Mar and Jack Twist, two cowboys who fall head over heels for each other in the spring of 1963. Their relationship endures for twenty years, never fully resolved, never fully let go of, and always surrounded by fear, confusion, and above all, by love. Brokeback Mountain depicted a story that was both accurate in its portrayal of queerness in the setting of its story, and in making it relatable to queerness and homosexuality today. Later, when turned into a movie, it broke even more barriers, and furthered its social effects on Hollywood and Society. Brokeback Mountain accurately describes the attitudes of society towards homosexuals in the 1960’s, specifically of those that live where the story took place. In the 1960’s, police raids of gay bars were routine, and extremely violent. The stigma associated with even the idea of being homosexual was crippling. It was considered a disease, and looked down upon severely. But finally, the gay rights movement was gaining its footing. During this time, influenced by the model of a militant black civil rights movement, the â€Å"homophile movement,† as the participants dubbed it, became more visible. Activists, such as Franklin Kameny and Barbara Gittings, picketed government agencies in Washington to protest discriminatory employment policies. But the south, the setting of Brokeback Mountain, was very different. Although these were great steps towards equality, many states in the south and west were very far behind. The treatments of gays shown in the story were painfully accurate. At one point, when Ennis and Jack reunite after four years, they fear what would happen if they got caught. Ennis tells Jack the story from his childhood, saying: â€Å"There was these two old guys ranched together down home, Earl and Rich- Dad would pass a remark when he seen them. They was a joke even though they was pretty tough old birds. I was what, nine years old and they found Earl dead in a irrigation ditch. They’d took a tire iron to him, spurred him up, drug him around by his dick until it pulled off, just bloody pulp. What the tire iron done looked like pieces a burned tomatoes all over him, nose tore down from skiddin on gravel.† (29) Incidents like this were not uncommon in the 60’s, and as horrifying as it seemed to read this passage in the book, what made it worse was the Proulx was in no way exaggerating, but rather relaying the harsh truth of the events that would occur during this time. Brokeback Mountain is still relatable to by many people, especially by those that can identify with the characters in the story. Wyoming, the state where Ennis and Jack met, is in an area of the United States that is still not completely supportive of the gay rights movement. In an article published in The New York Times in 2005, after the release of the film based on Brokeback Mountain, many people who identified as homosexual came forward to speak about their experiences. They grimly spoke about the intolerance they still face, and Derrick Glover, a 33 year old gay rancher said, â€Å"Where I live, you can’t really go out and be yourself. You couldn’t go out together, two guys, as a couple and ever be accepted. It wasn’t accepted in the past, it’s still not, and I don’t think it ever will be.† Glover came from a family of ranchers, and his family had herded the lands around their home for generations. He grew up â€Å"herding, branding, culling and haying, horses hobbled on picket lines and calves pulled forcibly from their mother’s bodies during spring calving,† and every summer he would set out with his brother in a panel truck carrying their two quarter horses, to compete in calf and steer roping competitions. His tale sounds just like that of Jack and Ennis, growing up and knowing nothing but being a cowboy, but just like Jack and Ennis, he would never have been accepted for who he was. Because of this, he was leaving his home and moving to an area with more people and more tolerance. This situation, oddly reminiscent of Stephen in â€Å"The Well of Loneliness,† is something that occurs shockingly often. At one point in the story, Ennis declares, â€Å"I ain’t queer,† despite the fact that he had sex with Jack. He refused to acknowledge that he could possibly be a homosexual, and that somehow, maybe, he could be falling for another man. Ennis is more masculine of the two, and in declaring his homosexuality, even to himself, he would be losing an aspect of his masculinity. Ben Clark, another man who spoke of being growing up on a ranch and being gay, said of it, â€Å"†But I had no idea what to do about it, ever. I was raised in a ranching, rodeo world – wrangling, packing horses, riding bucking stock, working in hunting camps – but always with the sense that I had to conceal who I was because cowboys could never be gay.† Cowboys have always been seen as men who are rough and wild, who face nature with stern faces and no fear, men whose masculinity was literally one of the main essences of their being, and this stereotypically cowboy image is w hat hinders the acceptance of so many homosexual men in the west. Of this image, Mr. Clark said, â€Å"†I could not accept being gay because of the stereotypes that were drilled into me†¦Gay men are emotionally weak. They are not real men. They are like women.† This sentiment, unfortunately, is echoed throughout much of the United States, and the rest of the world as well. By showing that these macho, strong, ranch hands and cowboys could be gay, Brokeback Mountain rejected the normative ideas of what is considered â€Å"queer† and â€Å"gay.† It showcased two homosexual men as regular men, and didn’t attempt to fit them into the stereotypical, effeminate image of gay men. Homosexual men used to be seen as perverts, men who just wanted to have sex with other men, but Brokeback Mountain destroys that idea. It shows queerness and homosexuality as what it truly is- love. It showcases the intense affection one person can have for another, regardless of their gender. In 2005, Brokeback Mountain was turned into a movie, and was met with great approval. Starring Jake Gyllenhall and Heath Ledger, the movie went on to receive many awards, including three Academy Awards for Best Director, Best Adapted Screenplay, and Best Score as well as four Golden Globe awards for Best Motion Picture – Drama, Best Director, Best Song, and Best Screenplay and four BAFTA Awards for Best Film, Best Director, Best Adapted Screenplay and Best Supporting Actor (Jake Gyllenhaal). The film also received four Screen Actors Guild nominations for Best Actor, Best Supporting Actor, Best Supporting Actress and Best Ensemble, more than any other movie released in 2005. It was a hit. More than that though, it reached thousands more people than it did as a book. What was once just a short story by a Pulitzer Prize winning author was now a major motion picture being shown all over the United States. It opened up people’s eyes, it started discussions, and it helped break down barriers in the normative stereotypes of what gay men were. Instead of just imagined characters, Jack and Ennis now had faces put to them, and these faces were well known actors. Leonard Maltin, a film critic and historian, said that Brokeback Mountain was â€Å"†¦ in some uncharted waters, because it shows what it’s like for two men to feel that kind of longing and passion for each other, and people aren’t used to that†¦No one movie is going to turn things around, b ut they can be building blocks. That could be this movie’s legacy.† The movie helped in attempting to erase Hollywood’s homosexual stereotypes, and to raise consciousness of gay rights. Gay rights groups immediately embraced the movie after it came out. The Gay and Lesbian Alliance against Defamation (GLAAD) established online resource guides for the movie. The guides had links to both articles and support groups for cowboys and ranchers who identified as homosexual, and who often felt confused and alone in the struggle with their sexual orientation. The Human Rights Campaign also joined in, issuing â€Å"Oscar Party Kits,† with posters of Brokeback Mountain, and cards that read â€Å"Talk about It† to encourage the discussion of gay rights. Brokeback Mountain put a new spin on cowboy stories. It showed the life of two queer cowboys, who could never fully give in to their love. It created a story that could have been plucked straight out of Wyoming in the 1960’s, through its accuracy and effectiveness. It was raw and real, and it was unapologetically showed the struggles faced by homosexual cowboys and ranchers, both in the 1960’s, and even today. The movie of the same name attempted to break down barriers in Hollywood, and it spread the story of Jack and Ennis even further, opening more people’s eyes to the reality of queer relationships, and how they don’t always fit into certain molds. Brokeback Mountain is a classic piece of queer literature, one that will continue to be both authentic and relatable for years to come.
