...Conceptos de señales de video relacionados con el ojo humano El ojo humano posee 2 tipos de sensores: - Conos (sensores de color) - Bastones (sensores de luminancia) Se le llama cuadro a la imagen que resulta después de la exploración de todas las líneas en que se ha dividido una imagen (imagen completa). Se le llama campo a una exploración completa de la pantalla (medias imágenes). Acuidad – capacidad del ojo en distinguir 2 líneas consecutivas. Típicamente α ” 1 minuto. Siendo D la distancia al ojo y H la altura de la pantalla, se toma generalmente [pic]. Cantidad de líneas horizontales: [pic] ” 572 líneas. La acuidad del ojo es cuadrada, pero como la cantidad de líneas verticales influye en el BW de la señal, se define la pantalla con una relación 4:3. [pic] ” 761 líneas. Persistencia – propiedad de que la imagen quede retenida en el ojo durante un corto espacio de tiempo, por lo cual se debe decidir cuantas imágenes enviar por segundo para dar la idea de movimiento y no molestar al ojo humano con el parpadeo al cambiarlas. Como el ojo retiene cada imagen por 0.1 segundos entonces 10 imágenes por segundo dan la idea de movimiento. Flickeo – depende de la luminosidad de la imagen y de la luz ambiente. La cantidad de flickeos debe ser mayor para no molestar al ojo. En cinematografía se toman 24 imágenes/seg. y se manda repetida la misma imagen (se ahorra cinta), por lo cual se toman 48 imágenes/seg. En TV, cada vez que cambia el cuadro...

...NTC 406 Week 3 Individual Assignment Bandwidth is a Rate at which electronic signals can travel through a medium, such as a wire, cable, or channel or capacity of network to transmit data on network. There are different transmissions medium such as audio video and voice. Bandwidth need is different in the all because these all are different data format. In analog transmission (such as of voice signals over copper telephone lines) bandwidth is measured in cycles per second (or Hertz); for example, a telephone conversation requires about 4,000 Hertz (4 KHz) of bandwidth. In digital transmission (such as of data from one computer to another) bandwidth is measured in bits per second (BPS); for example, modern modems can send and receive data at 56,000 bps (56 Kbps) over ordinary telephone lines. For the same amount of data, digital transmission requires more bandwidth than the analog transmission, and different types of data require very different bandwidths. For example, full motion video normally requires about 10 million bits per second (10 Mbps) bandwidth which is sufficient to carry 1,200 simultaneous telephone conversations. A typical voice signal has a bandwidth of approximately three kilohertz (3 kHz); an analog television (TV) broadcast video signal has a bandwidth of six megahertz (6 MHz) -- some 2,000 times as wide as the voice signal. Three bandwidth techniques involves are as like Traffic Management/QoS, Caching and Compression so these are different bandwidth...

...-Introduction: The work of the first NTSC (National Television System Committee) was built on the basis of earlier standardization attempts. The first NTSC laid the foundations that made monochrome television a practical reality in the United States. The standards it endorsed in 1941 are still in use today. At the dawn of color television it seemed at first that it was not going to be compatible with monochrome television and would need special receivers. A tug of war of compatible versus incompatible color television systems ensued. The compatible system won. The second NTSC set up the compatible standards that have been adopted by the U.S. and by the rest of the world in many major respects. Casual observers of technical progress often assume that the basic forces at work are merely those of new science and improved technology. But seasoned veterans of the technical wars know that many other forces are also at work. Prominent among them are the pride and prejudice of technical, industrial, and political leaders; the pursuit of power and profit; the rivalry for command of patents and markets; as well as the forces of government: inertia, misunderstanding, and, occasionally, foresight. The development of television in the United States is a prime example of the conflicting interplay of these forces and their ultimate resolution for the public good. The body on which these forces were principally brought to bear was the National Television System Committee. The first...

...those from whom we receive them, or only seldom. But the benefit we receive must be rendered again, line for line, deed for deed, cent for cent, to somebody” and this is exactly what “paying it forward” is. Kant says that morality is not just doing the right thing by helping other people, but doing it for the right reasons as well: simply because it is the right thing to do. He holds true that for an action to be moral, it must be done out of a principle which can be applied to everyone equally, a maxim that can be willed to become a universal law. The movie and the book, Pay it Forward, progressively rises towards the moral standards of Kant as the characters come to understand the meaning of this movement and their duty to the world. I saw a bumper sticker the other day that said, “Think globally, act locally.” That is what the kids in Mr. Simonet’s class are really being assigned to do and that is what the Pay it Forward movement demonstrates. We are all connected to each other. The world may be broken but in watching and helping those around us for the right reason, the benefits spread worldwide. Kant agrees that the world is broken, that the human condition is flawed or Trevor in the beginning says, “the world is shit.” Trevor looks at all the bad around him; the trailer homes, the bullies, all the starving homeless people. His mom is a drunk and working as a stripper, his dad is abusive and it is no mystery why an eleven year old would see all this and think the world sucks...

...merit pay involves giving employees a permanent pay raise based on past performance. Often the company’s performance appraisal system is used to determine performance levels and the employees are awarded a raise, such as a 2% increase in pay. I worked in a hospital and with nurses in an emergency room that got this exact raise. They had a cap that they could hit where they maxed out once they had been there for over 33 years they stopped getting the raise. The ever looming and potential problem with merit pay is that employees come to expect pay increases. This means it will be more so of an expectation and less so something earned. If you know something is coming either way, would you work harder for it? Not to sound lazy but time is valuable and why put in more time than everyone else for the same rewards? The only way to make merit pay more effective depends on making it truly dependent on performance and designing a relatively objective appraisal system. Without the appraisal system it is literally pointless. Ultimately, to be successful, the merit pay program must ensure that awards provided to the best performers will be substantially greater than increases awarded to average, or below-average performers. Merit pay when managed correctly provides a huge advantage for employers in my eyes. Merit pay helps an employer differentiate between performance of high and low performing employees and reward the performance of the higher performers. I believe that merit pay is worth...

...“What about everyone else? The problem may not be that executives are paid too much, but that employees are paid too little.” 2. Statement of the Problem Studied In this article, Mr. Delves examined why people complain about executive pay, how companies used to inflate employee earnings, and how companies can increase employee wages now. 3. Significance of the Problem Studied With sky rocketing pay for many executives over the last few decades, many employees have wondered why their pay has not also increased. In the past companies have used stock options to provide incentive for employees and to use these as a pathway to increase employee pay. However with the economic recession and many of the changes in accounting practices, companies could no longer use this incentive to increase wages for employees. Thus Mr. Delves presents the question, “what do we do about [increasing employee incentives]?” (Delves, 2012). If this question can be answered, it has the potential to not only increase employee productivity but also to provide them with increased opportunities. 4. Comments on the Article Many people complain and cannot understand why executives are paid so much money and why their pay continues to remain fairly constant. Delves states, “I have wondered for some time about why so many people continue to be so upset about executive compensation and corporate governance when we have made so much positive progress” (Delves, 2012)...

...Pay It Forward ETH 316 Pay It Forward “Pay it forward” is not only a movie but also an assessment of child which dialogues about Trevor’s life and his assignment. Let us consider the impending impact 11-year-old Trevor McKinney as portrayed by actor Haley Joel Osment. As seventh grade student who is challenged by his Social Studies teacher Eugene Simonet played by actor Kevin Spacey in an extra credit assignment to change the world. Living is difficult for the young Las Vegas resident Trevor and single mother Arlene played by actress Helen Hunt. Challenging issues of both physical and sexual abuse, along with extreme alcoholism plague the McKinney family. Arlene has dissociated from her son by her severe drinking problem and habitual poor decision making. She is a casino worker by day and strip club waitress at night. Her son Trevor is no run of the mill son. The child sees the potential difference he can make in a world that he does not like the look of. His plan for change is to influence the lives of three people. If the three people accept, it will become their duty and obligation to continue with his idea of “paying it forward”, instead of taking it back by impacting the lives of three other people. This becomes the idea of “one person reaching another” to “one person reaching out to three.” Ultimately the results can revolutionize the earth. The movie “Pay It Forward” is conveyed in an interesting present-day to earlier and back to the present type storyline by...

...Memorandum To: Asi Clen, Deputy Chief of Planning & Operations CC: Jay Willie, Director of Maintenance & Transportation From: Danisha Benjamin, Accountant Date: February 11, 2012 Subject: Request for Permission to Research Employee Parking Lot Construction Introduction The purpose of this memo is to request permission to pursue research on the opportunity of constructing a secured parking lot for employees of the Department of Human Services (DHS). With over 1,000 employees and over 300 clients daily, the Department of Human Services is one of the busiest organizations located on Hospital Street, St. Thomas. Besides Human Services, Bergs Home, a housing community known for criminal activities and Bethlehem Shelter, a temporary housing for the needy, are located in this area. At the rear of the building, directly across from Bergs Homes and next to Bethlehem Shelter, is a newly cleared area that has become the permanent parking for employees. Issue Without predetermined parking spaces, an average of 100 cars can fit in this area. Due to the lack of security, anyone can park in an available space. Often, clients, visitors of Bergs Homes, and volunteers of Bethlehem Shelter occupy this parking area. Consequently, parking for DHS employees is affected. In addition, during 2011, a string of robberies occurred in this rear parking lot. On different occasions, three employees were robbed at gunpoint. Other...

... Some things in life can go unsaid but then there are things that need a voice. One thing that gets on my nerves is the blue lot parking area at Bloomsburg University. The blue lot is a stone parking lot located in the far left corner of upper campus directly to the left of JKA apartments completely out of the way and a huge inconvenience for college students that use it. Not to mention the university charges seventy five dollars to park there. The university police locks down the gated entrance every night causing people to be locked in or out. My position on the rules and regulations of the parking lot is strongly opposed and feel that it should be free. Not only is it absurd to pay for this parking but also that at times you are not even allowed to get to your own personal vehicle that you pay large amounts of money just to have and insure. This cause’s nothing but large inconveniences from many college students but also puts the ones who use it in possible danger. The location of the parking lot causes a lot of inconveniences. It’s not very close and is a hike just to get there. If you happen to be a new freshman or just a student still living in the dorms it takes a while to get your vehicle. First you have to walk all the way up to Centennial Hall building and wait for the shuttle then you have to take that all the way up to the recently new JKA apartments. Once there you then walk all the way past the apartments and through the gates and then finally to your vehicle...

In review this information one will see that the world does not revolve our daily actions of life. The film gave a different approach in viewing the world and surrounding. The Second Line The purpose of this short film was to display how many individuals go about their lives living in a tunnel vision world. In the film Danny Glover the actor was shown as a business man who did not pay any attention to anything in his surrounding as he journey to work. In the world of which we all live many people are so caught up in their own world, not even taken the time to smell the flowers. People who tend to live in such a matter are not just blind to their own needs but also the needs of their community. The term tunnel visions which can be describe as one who is only focus on things within narrow vision. The main character of this film display this very term. This short film showed the main character who started out his day having car trouble. He really did not try any other options to see what the problem with his vehicle was. His goal was to get to work due to time that reflected on his watch. The issue I took from the...

...Henderson, author of the 2010 Salary and Satisfaction Survey, mentioned that more pharmaceutical companies are looking for more regulatory, stronger qualities, and knowing the clinical roles while hiring employees. Henderson (2010) also states that employees struggle with the workload pressure that tan employee can develop due to not being fully satisfied with the work environment. Situations that threaten your personal income or the fear of unemployment create an enormous level of stress. Authors Bang-Cheng Liu and Thomas Li-Ping Tang developed a study in China on the satisfaction of full-time public sector professionals as well as a part-time student. A quote that Liu and Tang mentioned in the article read, “Money per se does not lead to pay satisfaction. The value of a given reward is not absolute, but is relative to other rewards with which is compared (Greenberg and Ornstein 1983).” Personally I cannot speak on behalf of the...
