Demosaicing Using Artificial Neural Networks
By: Kyle Cooper
Electroencephalography is the recording of electrical activity along a person’s scalp. It measures the changes in voltage of this electrical activity. An EEG is the recording of these signals over a short period of time. It is often used to diagnose epilepsy, other forms of seizure disorders, and more. It works by attaching several pairs of electrodes on the patient’s head. These discs conduct electrical activity (the signal), transfer it through a wire to a machine that amplifies the signal (the system) for analysis. The conducted electrical activity measures the voltage on each pair of electrode and measure’s the difference between the two voltage values. This is the signal that is sent through the wire to the system. Therefore, this allows doctors to look at patterns between all of the pairs of discs and find abnormalities in the measurements. Using these abnormalities, they can diagnose a patient that they otherwise would have no way of diagnosing. Therefore, this is a very important technology in the medical field. It is also being researched for future forms of gaming. As our understanding of the brain increases, we can hopefully begin to interpret a patient’s thoughts based on the readings of the brain waves. If we reach this point, we can begin to develop technology that allows people to control things simply by thinking. This is especially useful for people who live with a loss of muscle control. Using this technology, they will hopefully be able to control things more and not need their muscles to do every day activities they otherwise couldn’t do. Therefore, this is an important technology for current as well as future generations.

Dollar Plunges to Record Low Against Euro2004-11-05 11:47:01 by ---
NEW YORK -- The dollar dropped to record lows against the euro on Friday, succumbing to negative sentiment and erasing all of the U.S. currency's earlier gains following a robust U.S. October employment report.
Technically driven trading also played a role in the dollar's fall.
The euro surged above $1.2900 and then breached the prior record high around $1.2927 hit in February, reaching new record peaks around $1.2950, according to Reuters data.
The dollar index, a measure of the U.S. dollar's performance against a basket of currencies , fell to a nine-year low. The U.S. currency also fell to six-month lows against the yen and 6-1/2 month lows against the Australian dollar.

I gave up watching tv about 3 - 4 years ago.2005-04-11 21:02:11 by FellowTraveler
I now use my tv for watching rented movies or programs I taped and collected before.
I do miss the history channel and other educational stations,
but over all I have more time for other activities the likes of this forum etc.
Now back to an issue of money :)
So called "free trade" works for this country under the guide lines of national security,
though the cost of this free trade is becoming very heavily taxed :)
This monopoly of money(currency) we are allowed to use - is controlled as it's tradable value-
One of the hidden taxation is inflation,
a million has the buying power of just a half million within less than a decade.
This fact keeps us on the treadmill of buy and selling (trading-investing),
else our savings soon...
