...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...

...The Rack of a Shotgun in the Night In the clear early Saturday morning around 4:30 am, I completed my shift on a part time detail at a popular hip-hop night club that I worked for off duty along with two additional officers. The club serves alcohol to the 21 year old and over crowd. The capacity level is reach quite frequently every Saturday night. The potential party goers who can not gain entry try to hangout in the parking lot of the club. The club owner employed several off duty police officers with myself included to deter in crime or incidents on the property after the club is closed at 4:00 am. My job was to ensure that no loitered in the dimly lighted parking lot of the club. I would walk the parking area in my full department issued uniform to give the show of officer presence to hinder any crime that could potentially take place. I checked to ensure there were no disputes physical or verbal in the parking area. A clear presence disrupted any vehicle theft or vandalism too. I walked the parking area and gave verbal instructions to individuals who sat in or just stood by vehicles to make entry to the establishment or depart the property. A combination of alcohol and poor judgement has been a factor with people who did not follow instructions in the parking area. At 4:00 am, one of the security guards for the club opened the front door and I could hear the DJ say that the club was closed. The loud music had stopped and people began to exit the club to the parking...

...Running head: ACTION INQUIRY RESEARCH PAPER- MERIT PAY Action Inquiry Research Paper- School Finance Jennifer Ponton Grand Canyon EDA 535 July 01, 2012 Action Inquiry Research Paper- School Finance Statement of the Problem This past spring thousands of teachers protested at the Louisiana State Capital to prevent Louisiana lawmakers from passing an educational reform bill proposed by Governor Bobby Jindall that would change the face of public education in Louisiana forever. Many superintendents and school personnel were relieved of their professional responsibilities on the days they protested hoping that they could sway the governor and the lawmakers from passing the bill. The bill was passed even without the support of many educational leaders and lawmakers in Louisiana. The laws passed by Louisiana lawmakers read like a conservative education reformer’s wish list. Teacher tenure in Louisiana after three years of employment was eliminated and replaced with teachers receiving a “highly effective rating for five out of six consecutive years of teaching. Back to back “ineffective rating will result in a teacher being fired. Seniority will no longer be a dominant factor in layoff decisions. In fact most decisions involving teacher employment and pay will now be the responsibility of both the principal and the superintendent of school. Before Governor Jindall’s reform plan it was the responsibility of the local school board. The reform proposed by the governor...

...Trent Dewberry Corporate Governance Case 7 September 11, 2012 The Board-Management Relationship After almost a full year as a member of the Mega Corporation Board of Directors, Jack Wright felt confident in his assessment of the functionality of the organization. Wright found that the company had a strong balance sheet, several successfully operating businesses, and some other businesses that could be sold. Yet Wright also found that there were several issues that were not being addressed. Wright found that somehow Sam Bigger was keeping John Rock from changing the governance structure of Mega. Bigger’s control of the company is the first barrier towards Mega’s progress as a company. The situation with Sam Bigger is a very common one with entrepreneurs. Sam Bigger started the company many years ago and has experienced a great deal of success. It is a difficult thing for a well accomplished business man to admit that the ways things have always been done are no longer effective. It has become evident that changes are needed in order to stimulate growth and improve business operations. Sam Bigger has so much control of the company that he is a hindrance to Mega and its operations moving forward. The question now is what action should John Wright take in order to break through the entrenchment of Sam Bigger? There are a few options that Jack Wright could take in this situation. Wright considered going directly to Bigger for a face-to-face discussion. Wright chose not to go...

...Form: Wal-Mart September 10th, 2015 Wal-Mart: The High Cost of Low Price focuses on the malicious strategies the company uses to solidify its place at the top of the retail industry. The documentary includes interviews from hard-working Americans and former Wal-Mart employees who share their stories of malpractice by the company. The first portion of the film details how Wal-Mart has ruined three-generation mom-and-pop businesses in small towns through the help of local subsidies and state legislature. Next, the film addresses the mistreatment of workers. Wal-Mart offers too few hours for employees to earn a living or gain benefits, its healthcare program is too expensive, and employees are often pressured to work overtime with no pay. Furthermore, the company has hidden camera surveillance and response teams to shut down union activities. Working conditions in China are also documented in the film and a former manager tells a story about how he was fired by the company for reporting the terrible conditions. Lastly, the film shows movements in communities around the U.S. to stop Wal-Mart from opening stores in their areas. For me, the most interesting point in the movie dealt with Wal-Mart’s environmental practices. In Belmont, North Carolina, a Wal-Mart near the Catawba River would sell herbicides and pesticides on pallets in the parking lot. As one of the River keepers said, every time it rained in the area the chemicals would run off from the parking and into...

...“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...
