NEW EYE TRACKING TECHNIQUES IMPROVE REALISM OF AIRCRAFT SIMULATORS A simulated flight environment for pilot training may soon be made more realistic through the use of eye-tracking technology developed by researchers at the University of Toronto's Institute of Biomedical Engineering (IMBE). Many safety and cost benefits are obtained by training aircraft pilots under simulated conditions, but to be effective the simulation must be convicingly realistic. At present, th e training facilities use large domes and gimballed projectors, or an array of video screens, to display computer-generated images. But these installations are very expensive and image resolution is low. Further, it would take an enormous amount of addi to improve image quality significantly throughout the whole viewed scene. However, based on the visual properties of the eye, realism can be obtained by providing a high-resolution 'area of interest' insert within a large, low-resolution field of view. If the image-generating computer 'knows' where the pilot's fixation is, it mage there. The technology to make this possible was developed by a research team headed by Professor Richard Frecker and Professor Moshe Eizenman. The work was carried out in collaboration with CAE Electronics Ltd. of Montreal with financial support from the Natural Sciences and Engineering Research Council of Canada. Their eye-tracker can record and analyze accurately up to 500 eye positions per second. The system works by means of capturing and processing the reflections of a low-level beam o f invisible infra-red light shone onto the eye. Multi-element arrays capture the image of the eye and digitize the information, which is then processed in real time by a fast, dedicated signal processing unit. The difference in position between the ligh tre of the pupil reveals the instantaneous direction of gaze. Developments by the IBME team have significantly increased the speed of signal processing in addition to enhancing accuracy of eye position estimates. Eizenman believes that "these improvements make our eye-tracker very effective in monitoring the large G-force environment where the pilot tends to make larger eye movements because of contraints which exist on movements of his head". In a new generation of aircraft simulators, under development by CAE Electronics Ltd. of Montreal, a head tracker which tells the direction of the pilot's head is mounted on top of the helmet. The eye tracker is mounted on the front of the helmet, and is ll exactly where the pilot's eye is fixating. Frecker said that "successful integration of our eye tracker into the novel helmet-mounted CAE flight simulator would result in a new generation of simulators that would likely replace the current large domes and cumbersome video display units." Initial tests of the integrated system will be carried out in collaboration with CAE Electronics at Williams Air Force Base in Arizona later this year.

Depreciate vs. Deprecate

Depreciate vs. Deprecate Depreciate vs. Deprecate Depreciate vs. Deprecate By Maeve Maddox The words depreciate and deprecate are from different Latin originals, but the difference in meaning between them is being eroded in popular usage. Depreciate is from Latin depretiare, a combination de (from) and pretium (price). â€Å"To depreciate† is to become less in value. Example: â€Å"It’s often said that a car depreciates as it is driven off the dealer’s lot.† Depreciate is used transitively with the meaning, â€Å"to lower the value of.† Example: â€Å"The latest crisis depreciated the currency.† Figuratively, depreciate means, â€Å"to belittle or disparage.† For example, â€Å"No matter what I do, he depreciates my efforts.† Deprecate is from Latin deprecari, a combination of de (from, away) and precari (to pray). â€Å"To deprecate† something was to â€Å"pray it away.† The word entered English in the 17th century with the meaning, â€Å"to pray against evil, to pray for deliverance from.† For example, one might go to church to â€Å"deprecate God’s judgment,† that is, pray that it might be averted. Deprecate has the secular meanings â€Å"to plead earnestly against† and â€Å"to express earnest disapproval of.† For example, â€Å"We deprecate the harsh action taken against the local population.† Speakers do not always see a difference between depreciate (to belittle) and deprecate (to disapprove of). Because the distinction is a fine one, the words have become mixed up. As a plain verb, deprecate is not as common as it was in the 19th century, but its present participle form occurs in the popular adjective self-deprecating. As defined at the online Oxford Dictionaries site, self-deprecating means â€Å"modest about or critical of oneself, especially humorously so.† Here are two recent examples of the usage: The iconic comedian [Joan Rivers]  passed away today at 81, but she leaves behind a legacy of unrestricted humor and self-deprecating wisdom. â€Å"Humor is an amazing quality to have,† Kunis told  Glamour. I like sarcasm, satire, self-deprecating humor.† In researching this post, I found several depreciatory comments directed at speakers who write self-depreciating instead of self-deprecating. The sarcasm that accompanies some of these comments is misplaced. According to the Ngram Viewer, self-depreciating predates self-deprecating by 20 years. For about 100 years, beginning in 1845 and continuing until the 1940s, self-depreciating is the more common term; then, self-deprecating soars to its modern ascendency and self-depreciating plummets. Etymologically speaking, self-depreciating is the better choice, but self-deprecating has triumphed in standard speech; self-deprecating is the version to use if you don’t want to seem ignorant. Merriam-Webster, by the way, defines self-deprecating as â€Å"given to self-depreciation.† Computer science has found a new use for deprecate: deprecated (adjective): Used typically in reference to a computer language to mean a command or statement in the language that is going to be made invalid or obsolete in future versions. Examples of deprecated in the context of computer science: A program element annotated @Deprecated is one that programmers are discouraged from using, typically because it is dangerous, or because a better alternative exists. Compilers warn when a deprecated program element is used or overridden in non-deprecated code. Apple has officially deprecated Java, the cross-platform runtime environment developed by Sun and now owned by Oracle, and the company has decided not to include Adobe Flash technology on its new super-slim MacBook Air notebook computers. Bottom line: to deprecate is â€Å"to disapprove,† but in â€Å"self-deprecating,† it means, â€Å"to belittle.† In the world of computing, deprecated means â€Å"phased out† or â€Å"soon to be phased out.† Depreciate is for talking about loss of monetary value.

A Research Paper

The Department of Education pronounces the addition of two more years in the basic education of students, which according to them will benefit not only the Filipino youth but all the Filipino in the Philippines. (Luistro, 2010) The administration asserts that with the implementation of such program, the problem of unemployment in the country will be resolved. In as much as employment in the Philippines is concerned, the K12 education also responds to the fact that most countries in the world already have the same plan in their educational institutions.With this, the standards of these countries go a notch higher than what the country has, thus, creating an expansion in the global competency. (DepEd, 2010) â€Å"We need to add two years to our basic education. Those who can afford pay up to fourteen years of schooling before university. Thus, their children are getting into the  Ã‚   best universities and the best jobs after graduation. I want at least 12 years for our public school children to give them an even chance at succeeding. † (Aquino III, 2011) K12 educational systems are additional years to secondary level. This research contains some information about curriculum of K12.This means that the present four years in high school will be called Junior High School and additional two years as senior High School. The model, which is being proposed, is K-6-4-2 where K means Kindergarten (5 years old), 6 means six years in elementary (6 to 11 years old), 4 means four years in Junior High School (12 to 15 years old) and 2 means two years in Senior High School (16 to 17 years old). (DepEd, n. d). Kindergarten will start in school year 2011 – 2012. The new and enhanced curriculum in Grade 1 and first year high school will start in school year 2012 – 2013.The first year senior high school or the eleventh year will begin in school year 2016 – 2017. The first graduates of the 12- year curriculum will be in 2018. (DepEd, n. d). Enhancing the quality of basic education in the Philippines is urgent and critical. The poor quality of basic education is reflected in the low achievement scores of Filipino students. One reason is that students do not get adequate instructional time or task. Our children deserve to receive the best education our country can provide for them and our economy depends on an educated and skilled workforce to be successful in the global market.B. Statement of the Problem This study aims to answer these following questions: 1. What are the advantages and disadvantages of the K-12 program or the additional 2 years to Basic Education? 2. Will the parents agree or disagree to the K- 12 program? C. Significance of the Study Parents of the students. This research would be able to help the parents of the students who are affected by the K-12 program, this will give them an idea of what will be the advantages and disadvantages of the program, and if it will help their children grow from the academic nature.Students. The students will benefit from the study by letting them know how they are going to be able to understand the addition of 2 years from their schooling. Students will know how it will provide a better quality of education to them. Teachers. This study will benefit the teachers from the school, for them to be prepared for the additional two years to the basic education. It is important for them to know the advantages and disadvantages of the program, because they will be the one providing the knowledge to the children. School.This research will also benefit the school, so they will anticipate the additional cost to the program, also the additional teachers and everything that they should be anticipating for. D. Scope and Limitation This study focuses only on the perception of the parents’ students affected by the K-12 program since it has been implemented this year the study will only focus on what the parents think and how it will affect them. It will also focus on the circumstances that will put one in favorable position, and those circumstances that will put one in unfavorable position. The study will only ask the parents about K-6-4-2 and not go beyond asking them if they’ll still let their children continue to study or not. E. Materials and Methods This research utilizes the descriptive method since the researcher aims to discuss and to know the perception of parents regarding to the additional years of basic education. The main goal of this type of research is to describe the data and characteristic what is being studied. The idea behind this type of research is to study frequencies, averages, and other statistical calculations.Although this research is highly accurate, it does not gather the causes behind a situation. Descriptive research is mainly done when a researcher wants to gain a better understanding of a topic. Interview, books and newspaper were researchers’ major instrument in gathering   Ã‚  Ã‚  information and were augmented with other data collected through readings E. Definition of Terms Department of Education. It is the executive department of the Philippine government responsible for the management and governing of the Philippine system of basic education.

Executive Summary - Essay Example the euro exchange economy can also be used to remove the lower bound which has an effect on the short period threatening free nominal interest (Buiter, 2010, p. 219). On the other hand, during price setting, New-Calvo-Woodford approach can be used in setting price. Their approach involve secretive division in the euro-currency financial system, government in the euro exchange economy, equilibrium in the euro currency economy, deterministic steady state in the euro currency economy and lastly the lower bound which can become a binding constraint in the euro currency economy (Buiter, 2010 p.223). In prevailing over the lower bound on nominal charge, one can use the following strategies: eliminating currency, disburse negative interest rates on money (Buiter, 2010) or taxing money or even dividing the standard of trade. The three methods of eliminating subordinate bound on nominal interest plays a role in making it possible to ensure that it target the true stability of prices (Buiter, 2010). The author use of quotes from outside source gives a back up to the points that are highlighted in the report. He used seventy outside sources to support his main ideas concerning the monetary policy. The examples used are ones that have methodology to come up with the main idea

Palliative care, on communication at the end of life - Assignment Example e family case, and in recording consistently the remaining days or hours of the patients as well as the responses of its family in these critical hours. 1. Preparing for a family meeting   -- This refer to the necessary requirements to be done by the care giver to set appropriate measure to communicate to the patient’s family. This stage may include formal or informal manner of putting across the message about the imperative of devoting fiduciary time together in order to prepare them psychologically and emotionally the possible termination of life. The nurse or care giver must ready all desired information available relating to the patient condition; the necessary or expected responses of the family; the needed medicines; and the desired emotional acceptance of patient’s family members to an impending unchangeable fate. 2. Conducting a family meeting  Ã¢â‚¬â€œ this refer to the actual meeting of the medical professional and nurses with the family to discuss empirically the condition of the patient. This is a sober condition where medical practitioners would persuasively convey to the family the patient’s state and the impending limitation of its life toward potential termination. This meeting should be conducted in confidentially, cordial but often straightforward, and delivered with certain level of empathy. Attending physician will be illustrating to the family that all medical care has been exhausted for the patient and that the necessary support care needed to remove potential hindrances that may impinge the optimal transference of supportive strategies from health care professionals to family who are recipient of palliative care. The meeting will likewise discuss the needed supportive care and plan for the next step intervention that are relevant and imperative to make palliative care effective for the dying. This is the most difficult part because the practitioner is called to balance one’s values in decision-making, these being the cornerstone,

The Role of Intuition and Improvisation in Project Management Essay Example for Free

The Role of Intuition and Improvisation in Project Management Essay Improvisation consists of a combination of intuition, creativity, and bricolage. Intuitions are rapid, affectively charged, holistic judgements arrived at without the apparent intrusion of rational thought. Improvisation and intuition represent two important and related aspects of management in general and of the management of projects in particular. There have been few, if any, studies that have examined the relationship between intuition and improvisation in the context of the management of projects. In this research we used a model of the relationships between project managers’ intuitive decision making behaviours, their use of improvisation and project outcomes in order to examine whether or not intuition is used in the management of projects, how it relates to improvisation and how intuition and improvisation are linked (if at all) to project outcomes. The research employed a cross-sectional survey design (N = 163) administered in two waves. Mediated multiple regression analyses revealed a number of statistically significant effects (p 0.05), namely: (1) there is a positive relationship between the use of intuitive judgements and improvisation; (2) there is a positive relationship between experience and improvisation; (3) there is a positive relationship between the use of intuitive judgements and experience; and (4) the use of intuitive judgements is related to externally focused project outcomes. These findings are discussed in terms of their implications for the following: role of intuitive judgements and improvisation in the management of projects; the ways in which both intuition and improvisation are conceptualised; and the training and development of project managers.

Evolution Essay -- essays research papers

Charles Darwin had two great themes in "On the Origin of Species" which accounted for the similarities and adaptations characteristic of living organisms. To account for the adaptations of organisms and those innumerable features that equip them for survival and reproduction, Darwin (and Wallace) independently came up with the central theory of evolutionary process: natural selection. Natural selection gives insight in to why organisms are the way that they are. Adaptations are phenotypic variants that result in the highest fitness among a specified set of variants in a given environment. In reference to humans, there are many traits that have been selected and adapted for throughout their evolutionary history giving them the characteristics that they have today. In this paper I will discuss some parts of the human body, which have been found to be selected for by the evolutionary mechanisms of natural selection, adaptation and mutation. Natural selection, adaptation, and mutations are three components of the evolutionary process, each one having either positive or negative effects on the other. What exactly is natural selection? There are many variations of the definition but most agree that it must include the following concepts: some attribute or trait must vary among biological entities, and there must be a consistent relationship, within a defined context, between the trait and one or more components of reproductive success, where "reproductive success" includes both survival and the reproductive processes themselves (Futuyma, 1998). Charles Darwin's theory of natural selection states "if variations useful to any organic being ever occur, assuredly individuals thus characterized will have the best chance of being preserved in the struggle for life; and from the strong principle of inheritance, these will tend to produce offspring similarly characterized." Regardless of how it is defined, natural selection and its action can have tremendous effects on the members of a population. It is natural selection that causes adaptation, and these adaptations evolve to ensure the survival of a species. Evolution, in a very broad sense, is defined as descent with modification and often with diversification (Futuyma, 1998). Darwin's idea of evolution was that it occurred by descent with modificatio... ...-carbohydrate, high protein diet. Certain metabolic adaptations were therefore necessary to accommodate the low glucose intake. Many indicate that the adaptive response to the low carbohydrate intake is insulin resistance(Miller, Colagiuri, 1994). A study done by J.C. Brand Miller and S. Colagirui proposes that insulin resistance offered a survival and reproductive advantage during the Ice Ages. This study also proposed that a carnivorous diet would have disadvantaged reproduction in insulin-sensitive individuals and positively selected for individuals with insulin resistance. Another factor mentioned was the various environmental factors that contributed to the low carbohydrate intake such as the types of foods that were available. The forces of natural selection on the evolutionary processes in humans can have a broad range of effects on the characteristics of humans. There are no concrete answers to some of the questions proposed in this paper, but time will soon tell exactly how the evolutionary mechanisms have effected the human race. The human species will continue to evolve as long as the mechanisms of evolution and environmental factors act upon us.
