Virtual Reality - What It Is And How It Works
Number of Words: 3281 / Number of Pages: 12
... you need to find ways
to create the illusion of reality with a piece of machinery known as the
computer. This is done with several computer-user interfaces used to
simulate the senses. Among these, are stereoscopic glasses to make the
simulated world look real, a 3D auditory display to give depth to sound,
sensor lined gloves to simulate tactile feedback, and head-trackers to
follow the orientation of the head. Since the technology is fairly young,
these interfaces have not been perfected, making for a somewhat cartoonish
simulated reality.
Stereoscopic vision is probably the most important feat ...

Hereditary
Number of Words: 979 / Number of Pages: 4
... is also inherited from your parents. Chromosomes contain the
information of a person's potential height, potential strength against
disease, and other physical characteristics.
A human being has 23 pairs of chromosomes in every cell in his or her
body (except reproductive cells). If, during a stage of growth, a fetus
somehow loses one of these chromosomes, the baby may die, or have a birth
defect. Since this error is written on their genes, they may pass it on to
their children, who may or may not have anything wrong with them.
The way a person looks, as I have stated, is hereditary. I ...

Biomedical Engineering
Number of Words: 939 / Number of Pages: 4
... He/she may work applying the patterns of living organisms to engineering design or engineering new approaches or products to improve human health and productivity. On the one hand, the biomedical engineer may use his/her knowledge of physiological systems to reverse engineer nature, creating, for example, artificial tissues and neural networks. “On the other hand, a biomedical engineer may use knowledge of engineering to create new equipment or environments for maximizing human performance, accelerating wound healing, providing non-invasive diagnostic tools, product design, or numerous other ap ...

Surface Tension
Number of Words: 617 / Number of Pages: 3
... shape of a soap bubble, which is
the result of the distribution of tension on the thin film of soap, is another
example of this force; surface tension alone can support a needle placed
horizontally on a water surface.
Surface tension depends mainly upon the forces attraction between the
particles within the given liquid and also upon the gas, solid, or liquid in
contact with it. The molecules in a drop of water, for example, attract each
other weakly. Water molecules well inside the drop may be thought of as being
attracted equally in all directions by the surrounding molecules. However if
surface mo ...

Ground Water In Ontario
Number of Words: 1970 / Number of Pages: 8
... above groundwater supplies everyday, without the slightest notion of the extent to which they rely on this over-used and exploited natural resource. Canada as a whole "has far more water underground than on the surface - perhaps 65 times more than in surface lakes and streams",(Gorrie 70-71), and the same holds true for Ontario. Outside of the major urban centres which rely predominantly on surface sources for their water, most of Ontario relies on groundwater supplies. Although these groundwater supplies are abundant, not all are usable. In some cases the water has been polluted - as is the case in ...

... the lagoon and is broken down by anaerobic bacteria over several months. The liquid rises to the top and is collected and sprayed over nearby fields.
Many problems come with the lagoons. North Carolina is one of the top hog producing states in the country. On June 21, 1995, North Carolina suffered the largest agricultural waste spill in its history: a 7.5-acre, 12-foot-deep lagoon leaked 25 million gallons of hog waste into the headwaters of the New River near Richlands. The waste from the 10,000-head operation, owned by Oceanview Farms, contaminated the water for several miles downstream, increa ...

Down Syndrome 2

... is 46, however the
excess material from the twenty-first chromosome results in the
affects of the syndrome. With translocation, most cases occur
sporadically, with no bearing on maternal age. These two types
of this syndrome are very rare, being responsible for only 6 or
7 percent of all cases.
Children with Down syndrome are at high risk for health
problems. These include congenital heart defects, respiratory
problems, increased suseptibility to infections, and/or
obstructed digestive tracts. Leukemia has a greater frequency
of appearance among children with Down syndrome, and adults ar ...

Cisc And Risc Processor Technologies
Number of Words: 1812 / Number of Pages: 7
... you will also be able to describe the major differences between a CISC instruction set and a RISC instruction set and list some key advantages and disadvantages of RISC as compared to CISC
2. Introduction
Speeding up a computer system involves many different strategies. By speeding up the input and output devices in different peripherals. But the most fruitful place to speed up the system is by designing a faster processor. This report will explain "CISC" and "RISC" technologies and show how computer designers have tried to do speed up processors by implementing these tow technologies. ...

... installation of different focal plane
instruments, with in-flight accessibility, provided by investigators selected
from the international science community. The Observatory objective is to have
an operational lifetime in excess of 20 years.
The SOFIA project is in the early full-scale stage. The start of detailed system
design is anticipated in the Fall of 1996. The German Space Agency (DARA) is a
partner with NASA in the SOFIA project. DARA will provide the telescope and NASA
will provide the rest of the facility including the 747 aircraft, aircraft
modifications, on-board mission control system, ...
