like taking pictures on Earth, astronomers have to deal with many issues with distortion when it comes to taking images. The solution to this issue is a technology called adaptive optics (often referred to as AO), which was originally used to improve the performance of optical systems on ground based telescopes. [1] Adaptive optics are made up of mirrors, that can be reshaped that are controlled by computers. These mirrors fix the distortion caused by the turbulence of the Earth’s atmosphere. This
steps taken to make the Internet more disabled-friendly, which indeed there is. By taking advantage of adaptive technologies, using proper etiquette when sending email, and designing web pages with the disabled in mind, the Internet will soon become useful to more people than would otherwise be the case. One of the major advances in helping the disabled is the use of adaptive technology. Adaptive technology can be described as any hardware or software used to provide alternative methods of input
stress as a normal adaptive syndrome, a fight-or- flight situation, very similar to escape behavior (1). Stress is defined as "the set of all organic reactions to physical, psychic, infectious, or other, aggressions, which are capable to disturb homeostasis" (1). Stress lies at the intersection between personal, social, and economic factors and biology. Although stress is an important, integral part of our existence, there is a point at which it becomes overwhelming and our adaptive responses may break
committed crimes while serving their time. The movie shows how the prisoners come together when a former well-respected general is sent there to overpower the man that runs the facility. The first theory and probably the most noted theory is the Adaptive Structuration Theory of Marshall Scott Poole. Poole’s theory states, “Members in groups are creating the group as they act within it… A lot of times people in groups build up structures or arrangements that are very uncomfortable for them, but they
the nearly blind and for the deaf, including on screen text to synthesize speech or Braille, and adaptive hardware that transforms a computers audible cues into a visual format. Computers have given the limited back their freedom to be an active part of the human race. According to the Americans with Disabilities Acts, any office that has a staff of more than fifteen people now has to provide adaptive hardware and software on their computers, so that workers with disabilities can accomplish many tasks
state. However, while a certain amount of stress is necessary for survival, prolonged stress can affect health adversely (Bernard & Krupat, 1994). Stress has generally been viewed as a set of neurological and physiological reactions that serves an adaptive function (Franken, 1994). Traditionally, stress research has been oriented toward studies involving the body's reaction to stress and the cognitive processes that influence the perception of stress. However, social perspectives of the stress response
ATRAC: Adaptive Transform Acoustic Coding for MiniDisc Abstract -------- ATRAC is an audio coding system based on psychoacoustic principles. The input signal is divided into three subbands which are then transformed into the frequency domain using a variable block length. Transform coefficients are grouped into nonuniform bands to reflect the human auditory system, and then quantized on the basis of dynamic sensitivity and masking characteristics. ATRAC compresses compact disc audio
Working with the Handicap Ski Program The roots of adaptive skiing were in war and accidental injuries. In 1942 Franz Wendel was the first person to enter a competition for people who are handicapped. After suffering a leg amputation in the war, he fashioned a pair of crutches and attached them to short skis enabling him to crutch ski. By the late 1940's the Austrian Ski Association was financing a division for handicapped skiers while at the same time European and American programs at army hospitals
Inuits of Greenland: An Adaptive Society In a world far different from our own in the Northern Hemisphere lies an indigenous society known as the Inuits. Specifically focusing on the Inuits of Greenland these people have adopted various risk management strategies which has enabled them to survive in a harsh arctic environment. In indigenous cultures, their well-being and sustainability is managed through control of population growth like most present day indigenous societies have been influenced
language. There are three different systems for the speaker. * Speaker dependent system. * Speaker independent system. * Speaker adaptive system. Speaker Dependent System. A speaker dependent system is developed to operate for a single speaker. These systems are usually easier to develop, cheaper to buy and more accurate, but not as flexible as speaker adaptive or speaker independent systems. Speaker Independent System. A speaker independent system is developed to operate for any speaker
Adaptive leadership is becoming widespread in the United States Army amongst junior officers in leadership positions that require quick thinking and innovation. Leonard Wong discusses how the versatile and unpredictable enemy and situations in Iraq produces adaptable junior officers. These officers are learning to make decisions under chaotic conditions and are becoming more mentally agile. The Army is changing. The Army is transforming its capabilities in the war in Iraq to be effective and successful
Summary We have to develop an adaptive thresholding system for greyscale image binarisation. The simplest way to use image binarisation is to choose a threshold value, and classify all pixels with values above this threshold value as white and all other pixels as black. Thresholding essentially involves turning a colour or greyscale image into a 1-bit binary image. If, say, the left half of an image had a lower brightness range than the right half, we make use of Adaptive Thresholding. Global thresholding
was found. The new genus was assigned because this hominin had a combination of derived facial and primitive neurocranial features. This hominin is guessed to be about 3.5 million years old. The findings lead the scientists to an early diet-driven adaptive radiation, which gives insight on the craniodental features, or the structure of the skull and mouth. The name of the species is Kentanthropus platyops (the Flat-Faced Man of Kenya). This fossil was found in a rugged desert-like site on the western
and in their own biological processes .Beginning with the first few moments of life, a person learns to meet change by being adaptive. A person’s very first breath depends on ability to adapt from one environment to another. As indicated by the first quotation introducing this essay, each hour is different, offering people new experiences. Since human beings are adaptive and familiar with change, how is it that they often resist change in their work environment? This question had troubled managers
illness. Roy’s view of the person as an adaptive system took shape from this early work, with the congnator and regulator being added as the major internal processes of the adapting person. After 17 years of work with the faculty at Mount St. Mary’s college in Los Angeles, the model became the framework for a nursing-based integrated curriculum, in March 1970, the same month that the first article on the model was published in Nursing Outlook. The four adaptive models were added as the ways in which
Polarization Introduction: PART ONE: POLARIZATION Method 1: Two polarized disks were put into a grooved holder with their polarization axes lined up, and a bright red light emitting diode (LED) was placed on one side, and a light sensor was placed on the other side. Light intensity was measured as a function of the plastic rotating polarizer angle from 0 to 180 degrees. Science Workshop was used to measure the intensity for every 5-degree rotation (Fig 1). Method 2: The mineral calcite
Investigating the Speed of Water Waves Introduction In this experiment I will be investigating the wave speed, of waves on water in a tray, and how this speed is affected. Waves can be longitudinal, when the particles move in the same direction as the direction of the wave, or it can be transverse, when the particles move at 90o to the direction of the wave. Water waves are transverse waves even though transverse waves cannot travel through liquid. This is because the waves travel
at the age of 75 in Syracuse. It is said that he was killed by a Roman soldier, who was offended by Achimedes, while the Romans seized Syracuse. Archimedes had a wide variety of interests, which included encompassing statics, hydrostatics, optics, astronomy, engineering, geometry, and arithmetic. Archimedes had more stories passed down through history about his clever inventions than his mathematical theorems. This is believed to be so because the average mind of that period would have
At the University, he studied both physics and medical physiology. There, his doctoral teacher was Andreas von Ettingshausen. Mach received his doctorate in physics in the year 1860. Earlier his work was composed of working on the Doppler Effect in optics. After receiving his doctorate, Mach went on to teach mathematics as a professor at the University of Graz. He was a doctoral advisor to Heinrich Gomperz, another austrian physicist. Although he was teaching mathematics, his interests were still with
Robert Bunsen and Niels Bohr. The discovery of Fraunhofer lines was based on earlier work in the field of optics, and lead to many discoveries in astronomy, chemistry, and physics. In 1604, Johannes Kepler published the book Astronomiae Pars Optica. The book has been considered by many to be the basis of all modern optics. In his research, Kepler discovered many of the fundamental principles of optics (Molecular Expressions). He discovered how the eye bends light in order to form an image. He was one
