Compression Algorithms Research Paper Example | Topics and Well Written Essays - 1750 words

Compression Algorithms - Research Paper Example This process of size reduction of data is popularly known as compression of data, though it was formally known as source coding. Compression is important as it aids in cutting down the use of resources, like space of data storage or capacity of transmission. As compressed data should be decompressed in order to use, the extra processing computation or costs that arise from decompression, the situation differs far from free lunch. Algorithm compression is likely to be subjected to a trade off of time space complexity. For example, a video compression scheme needs a costly hardware to decompress the video with speed for it to be observed during the decompressing process. Opting for decompression of the video before watching may be of inconvenience or may need additional storage. Data compression design schemes entail tradeoffs amid various factors, inclusive of compression degree, distortion introduced and required computational resources to uncompress and compress the data. There are new options for traditional systems that sample fully then compress providing effective usage of resource based on compressed sensing principles. Compressed sensing methods circumvent the requirement for compression of data choosing from a selected basis. Origin The compression is either lossless or lossy. ... Compression is important as it aids in cutting down the use of resources, like space of data storage or capacity of transmission. Algorithm compression has played an important role in IT from the 1970s. During this time, internet was growing in its popularity and there was invention of Lempel-Ziv algorithms. The Lempel-Ziv algorithm unfortunately, has a stretched history in non-computing. The earliest invention of compression algorithms is the Morse code that took place in 1883. It involves the a compression of data entailing common letters found in English like t and e which are allocated Morse codes that are shorter. Later, when mainframe computers started taking hold in the year 1949, Robert Fano and Claude Shannon invented coding that was named Shannon-Fan. Their algorithm allocates codes to cipher in a specific data blocks based on likelihood of occurrence of the symbol. The probability being of one symbol occurring is indirectly proportional to the code length which results to a shorter means of representing data (Wolfram, 2002) After two years, David Huffman as he studied information theory shared a class with Fano Robert. Fano issued the class with the option of either taking final exam or writing a research paper. Huffman made for the research paper that was on the topic of working out on the most effective binary coding method. After a research carried out for months that proved not to be fruitful, Huffman almost gave up on the work to study for a final exam to cover for the paper. At that point is when Huffman got an epiphany, building a technique that was more efficient yet similar to the coding of Shannon-Fano. The major difference between Huffman and Shannon-Fano is in the later is there is a bottom-up built

Software - Essay Example Additionally, it is against the software piracy policy and rules those outline that a software licensing rules must be followed. In this scenario, there is a need to strictly follow these rules and regulations to avoid any legal actions. In addition, software piracy is about illegal copying a software application. It is recognized as an unethical activity that negatively affects all the users by driving up costs as well as minimizing funds for development and research of future software developments. Furthermore, it is a negative practice that is currently catching attention of software industry trade associations (National Academy of Engineering). The use of an unlicensed copy of a software application is totally illegal and unethical. In fact, it can increase the number of thefts thus this kind of activity should be neither tolerated nor practiced at TI. Consequently, how would we manage any other circumstances concerning potential misuses of a technology based assets? Can we ignore the illegal borrowing or change of a $200 for an application or other piece of system that is associated either to roommate or to fellows? Of course not (National Academy of Engineering; Shelly, Cashman and Vermaat). On the other hand, at the present, the majority of students believe that they are supporting and helping one another by sharing licensed software with other students. They believe that software costs are prohibitively high, and consider that, as students, they should not bear such extensive software costs. In this scenario, there are numerous solutions for the effective management of these issues. One of the primary solutions of such issue is the online websites where they can purchase such software at low cost by providing details of their institution and student enrollment. Another very good solution is that, institutions can as well establish their membership with the student welfare programs where

The reproductive system Essay Example | Topics and Well Written Essays - 1250 words

The reproductive system - Essay Example The penis consists of three columns of erectile tissue wrapped in connective tissue covered with skin. The penis has a root, body (shaft), and glans penis. The corpus spongiosum expands at the distal end to form the glans penis. The urethra extends throughout the length of the corpus spongiosum and opens through the external urethral orifice at the tip of the glans penis. A loose fold of skin, called the prepuce, or foreskin, covers the penis (Young et al, 2000). The male sexual response includes erection and orgasm accompanied by ejaculation of semen. Follicle-stimulating hormone (FSH) stimulates spermatogenesis; luteinizing hormone (LH) stimulates the production of testosterone; and testosterone stimulates the development of male secondary sex characteristics and spermatogenesis (Young et al, 2000). A womans reproductive cycles last from menarche to menopause. The female reproductive organs include the ovaries, Fallopian tubes, uterus, vagina, accessory glands, and external genital organs. The organs of the female reproductive system create and maintain the female egg cells (ova). It transports the ova to be fertilized by sperm, provides a location for the developing fetus and moves the fetus out at the end of the development period as well as producing female sex hormones (Young et al, 2000). Ovaries, the primary female reproductive organs, are solid structures about the size and shape of an almond located in shallow depressions, ovarian fossae, one on each side of the uterus, in the lateral walls of the pelvic cavity (Young et al, 2000). Two uterine tubes, Fallopian tubes, are connected with each ovary. Once inside the Fallopian tube, the oocyte is moved along by the rhythmic beating of cilia on the epithelial lining and by peristaltic action of the smooth muscle in the wall of the tube. The passage through the Fallopian tube takes about seven days and because the oocyte is fertile for only 24 to 48

The Role of the HIM Manager Essay Example | Topics and Well Written Essays - 3000 words

The Role of the HIM Manager - Essay Example The health care industry was the largest industry in 2006 which provided 14 million jobs in addition to 438,000 jobs for the self employed (BLS, 2008). The health care industry delivers care round the clock to millions of people. This requires combining the medical technology with the human touch. The health care industry consists of nine different segments – hospitals, nursing and residential care facilities, office of physicians, office of dentists, home health care services, offices of other health care practitioners, outpatient care centers, other ambulatory health care services and medical and diagnostic laboratories. The hospitals constitute only 1 percent of all healthcare establishments but they employ 35% of all workers. Workers in health care tend to be older than workers in other industries. Health occupations require high level of education and training due to which the health care workers are more likely to remain employed in the same occupation. Health Informatio n Management (HIM) Professionals are vital to any health care organization. This paper will discuss their job description and responsibilities, the challenges they face in discharging their duties and their responsibility towards handling legal and regulatory issues. The HIM professionals are also known by other designations such as Administrative Support Personnel, Health Care Technologist, Health Record Technician, Information Clerk, Information Specialist, Medical Technologist, Office Personnel (Alberta, 2007). The health records in any health care centre contain records about the patients’ history and courses of treatment. These may also include the physicians’ note, forms for prescribed medication, input from other members of the treatment team. While the health records departments are open for longer hours the HIM professionals work in shifts and generally work a standard work week. Their work profile entails spending the better part of the day at the

I want to buy health insurance by myself - Essay Example Thus, this factor underlines the case importance of medical cover, which comes in a variety of programs for an individual to make a choice. As students, we also need to plan for any misfortune, since we cannot tell of future occurrences. However, what happens when you cannot rely on a program meant to help you in case of a misfortune? Does such a program guarantee you a safe future? While acknowledging the Oklahoma Christian University Administration’s noble intentions in their medical cover program, this expose posit that the cover does not meet its intended purpose and hence the administration should allow students to arrange for their own cover. The initial purpose of any health insurance, or a medical cover, is to ensure that there was proper care of an individual’s body and health. In this regard, a medical cover should be a permanent arrangement that we can all rely on and avail at the appropriate time in case of a serious health disorder. In this regard, an individual’s health is at risk once the medical cover is not dependable. Case in point, our University’s medical cover is not one of the reliable. For instance, a colleague became sick, while in school, and we had to dig deep into our pockets and arrange for an ambulance, which took him to the hospital. This is despite the fact the colleague had paid for medical cover in the University. Thus, the failure of the University to meet such basic costs underlines the undependable nature of the medical cover. At this instance, we pause and ask the question of what would have been the consequence of us not raising money for the ambulance. This can only m ean that the investable would have happened. While medical cover should keep you insured against serious illnesses, our University cover does not cover even the most of basic illnesses like vision and teeth. We all know that

The Black Cat by Edgar Allan Poe Essay Example | Topics and Well Written Essays - 1500 words

The Black Cat by Edgar Allan Poe - Essay Example The narrator does not seem to be the slightest troubled by the apparent loss of both his wife and his sanity. Through the narrator, Poe leads you on with a drastic chain of events and inner thoughts. He builds the story upon his detailed description of the events that took place and leads the reader into overdrive with astonishing actions. It follows that the literary element most notable in The Black Cat is Poe’s utilization of the narrator’s point of view to advance moral and psychological investigations. This essay then considers the narrator’s first person perspective and examines the ways that it is utilized to advance the literary and narrative elements of moral structure, characterization, and narrative elements. Edgar Allen Poe’s use of the narrator’s point of view in The Black Cat furthers the story’s moral dilemma in many regards. One of the most prominent ways this occurs is in its consideration of the man’s relation with his wife. While in great degree he treats her poorly and is a dysfunctional human being, she is depicted, even through his admittedly perverse perspective, to be an upstanding and humane individual. It follows that the woman’s depiction as an upstanding individual who cares for animals functions to increase the reader’s sympathy for her after the man ruthlessly murders her with the axe. It’s also notable that the man, while feeling remorse and debilitating guilt after murdering the cat, feels virtually no such guilt after murdering his wife. In these regards, the narrative reveals an element of his psychological perversion. While this event is perhaps the most significant in terms of criminal actions, one can just as easi ly identify his torture and eventual murder of the original cat as the narrator’s most strikingly perverse and immoral acts. Poe makes excellent use of the 1st person perspective in gauging the significance of this event to the narrator’s psyche. He

The plan includes the increase of the number of field interviews by all officers on the watch in order to check all the crimes against the elderly so that it will be monitored and determined if how such crime occurred, and when the offenders commonly attack. It will also be included in the action plan to monitor crime analysis by each reporting district and location in order to identify the hotspot areas in the community where robbers usually performed their activities. The police department will also initiate a business watch and liaison program with local merchants in order to prevent armed robberies in the area as well as to maintain peace and order within the business vicinity. And this can be achieved by maintaining periodic observation and increasing of police enforcement in the area. The department will also initiate and increase patrol of officers on bikes, cars and foot patrol during the holiday season throughout the community. ... Aside from those, the unit action plan also considered the involvement of the community in solving the issue by formulating a neighborhood watch program. In order to do so, the police department will be conducting a town hall meeting to inform and keep them aware regarding of this issue. The police department will also remind the community to be cooperative and vigilant or alert if ever they see or observe anyone in the area who has suspicious actions and to call 911hotline for emergency assistance and or report to patrol officers. The effective implementation of this action plan lies in the hand of the personnel involved. And these include the chief of police or sheriff, police officers and assigned watch personnel. It is the prime responsibility of the police department chief or head to look over whether the plan is working towards their objective. Likewise, the police officers and watch personnel will be responsible in performing their specific assigned tasks. The involved personn el will also work closely with other units such as the crime prevention unit, investigation unit and the compstats and will be deployed in the community in order to increase police visibility in the hotspot locations to reduce street crimes. Since, the Bailey Police Department is composed of 14 police officers; it will be divided into two squads in order to patrol and monitor the community 24 hours a day, 7 days a week in alternate schedule. In the implementation of the said programs and projects, the department will be utilizing the normal assigned equipment for the police officers such as the service handgun and ammunition, holster, portable radio with carrier, handcuffs, binocular, night vision devices and
