The Artificial Intelligence community sought to understand human intelligence by building computer programs, which exhibited intelligent behavior. Intelligence was perceived to be a problem solving ability. Most human problems appeared to have reasoned, rather than mathematical, solutions. The diagnosis of a disease could hardly be calculated. If a patient had a group of symptoms, then she had a particular disease. But, such reasoning required prior knowledge. The programs needed to have the “knowledge” that the disease exhibited a particular group of symptoms. For the AI community, that vague knowledge residing in the minds of “Experts” was superior to text book knowledge. So they called the programs, which solved such problems, Expert Systems.

Expert Systems managed goal oriented problem solving tasks including diagnosis, planning, scheduling, configuration and design. One method of knowledge representation was through “If, then...” rules. When the “If” part of a rule was satisfied, then the “Then” part of the rule was concluded. These became rule based Expert Systems. But knowledge was sometimes factual and at other times, vague. Factual knowledge had clear cause to effect relationships, where clear conclusions could be drawn from concrete rules. Pain was one symptom of a disease. If the disease always exhibited pain, then pain pointed to the disease. But vague and judgmental knowledge was called heuristic knowledge. It was more of an art. The pain symptom could not mechanically point to diseases, which occasionally exhibited pain. Uncertainty did not yield concrete answers.

The AI community tried to solve this problem by suggesting a statistical, or heuristic analysis of uncertainty. The possibilities were represented by real numbers or by sets of real-valued vectors. The vectors were evaluated by means of different “fuzzy” concepts. The components of the measurements were listed, giving the basis of the numerical values. Variations were combined, using methods for computing combination of variances. The combined uncertainty and its components were expressed in the form of “standard deviations.” Uncertainty was given a mathematical expression, which was hardly useful in the diagnosis of a disease.

The human mind did not compute mathematical relationships to assess uncertainty. The mind knew that a particular symptom pointed to a possibility, because it used intuition, a process of elimination, to instantly identify patterns. Vague information was powerfully useful to an elimination process, since they eliminated many other possibilities. If the patient lacked pain, all diseases, which always exhibited pain, could be eliminated. Diseases, which sometimes exhibited pain were retained. Further symptoms helped identification from a greatly reduced database. A selection was easier from a smaller group. Uncertainty could be powerfully useful for an elimination process.

Intuition was an algorithm, which evaluated the whole database, eliminating every context that did not fit. This algorithm has powered Expert Systems which acted speedily to recognize a disease, identify a case law or diagnose the problems of a complex machine. It was instant, holistic, and logical. If several parallel answers could be presented, as in the multiple parameters of a power plant, recognition was instant. For the mind, where millions of parameters were simultaneously presented, real time pattern recognition was practical. And elimination was the key, which could conclusively handle uncertainty, without resort to abstruse calculations.

Article Body:
If you have more than one computer at home, you are probably better off connecting them or networking them together to use the same resources and receive the same internet connection. A home network is very easy to build. Here are some tips.

There are two main types of home networks, wired and wireless. While wired home networks are popular, but they require you to run wires from one computer to another. You might have to drill holes in a wall or run wire under the carpet.

If you don’t want cords running all over the place, you can easily get rid of them with a wireless home network. Wireless home networks are extremely simple to set up. You only need a wireless router and a wireless networking card for each additional computer you would like to hook up. Most wireless networks can send and receive data lightning fast at megabytes per second.

Wireless networks are extremely inexpensive, you can hook up a few computers for less than $200. The great part of wireless networks is that all computers on the wireless network can use the same internet or other resources such as a scanning machine and printer. So if you are looking for a great way to share data and resources among your home computer, choose to build a home network.

Whether you are a professional or a student or a desperate housewife who would always try to cook the breakfast at the right time for her husband; your MORNING determines how you would spend the whole day. A healthy morning makes your day more energetic and keeps you out of being groggy through out. So it would really be a great fun to type down something on this topic and share some insights. I was pondering over the topic and wondering where to start exactly and got stuck by a blog "Alarm clocks are bad. How to wake up and feel better" suddenly while searching through Google. Fantastic topic and I would certainly love to spend some minutes on topics like this one. The very first few lines, "Waking up abruptly by the sound of an alarm clock is an inherently unnatural thing to do. Sometimes you can wake up after 8 hours and feel like crap. Other times, you can wake up after 6 hours and feel completely rested. The problem lies in what you're doing when you're suddenly woken up from your slumber..." [Quoted from veenix.blogspot.com]

Really the traditional alarm clocks are the nothing but the most disturbing instruments that ever can be kept beside your bed. If we dig out every psychological problem due to abrupt morning sessions, I would say in most cases we would discover this crap as the one of the possible reasons. But this is my personal assumption and no one should be so much decisive about the fact or opinion imparted above as everyone has his/her right to speak. The more general approach would be that not all alarm clocks are bad enough. Technology has advanced a lot and lot of research and development put into this and as a result some great and innovative products have come out to the market. Alarm clocks with radio from brands like Jwin, Jensen, Cobra, ConairPhone and some other brands are really pretty popular among folks. These alarm radios are not only popular for their trendy look and multifunctional features, but also for their innovative technology. Let's draw a comparison in between traditional alarm clocks and these advanced alarm clocks with other useful attachments.

Traditional clocks have not been so helpful only because of their harsh sound. You need to set the alarm before going into bed; otherwise you may get up late in the morning. I still have one such traditional alarm clock that is still capable enough to scream all through morning. But I've replaced that one with a new alarm radio and kept that in my collection closet. On the other hand these new generation alarm clocks are very useful and worthy to keep beside the bed lamp. Alarm clocks with radio can let you tune in to the radio instead of harsh buzzer. Just set your radio with low volume that you would expect enough to wake you up as well as not that harsh and go to your bed without being worried about your delayed get up. Another significant fact is, DO NOT follow anybody blindly. You understand yourself and your activities better than anybody else. So it would be advisable to consult with your doctor for better tips and consult with an alarm clock expert would be very useful. After all it's the Good Sleep that Matters to us. Here follows some information that can let you buy some great alarm clocks with radio, phone, projector, DVD player and many more at better price.
