Samsung series 5- 5530 lcd tv

The advent of the computer has changed the way engineers develop the television. Samsung series 5- 5530 lcd tv The quality of the picture and sound on today’s televisions has far surpassed the standard of a mere decade ago. The new Samsung HDTV line and their features are a testament to that.

Starting with the LN-s4692d, this TV has a 46-inch screen and an option called the dynamic contrast which enables the owner to adjust the screen's back light based on the quality of light in the room.

Another option is the "S-PVA" feature which allows you to watch the screen easily no matter how you are angled in front of the TV.

Although all TV’s aspire to reach 100 percent of the color array of the National Television System Committee Standard, at 92 percent, the LN-s4692d surpasses most of the televisions in the market today which are usually around 73 percent. In this way, you are able to enjoy a highly detailed and realistic picture.

HPs5033 is another television under the new line of Samsung HDTVs. This plasma TV has a feature called the Gen-5 that addresses the issue of the glare on a screen when in a room with bright lights. With Gen-5 you can get a clear picture not matter how bright the lighting is in the room. And the HPs5033 is able to display more than five hundred and forty nine billion colors so you get a very detailed picture.

There is also an improvement to the design that should be pointed out. Unlike other TV’s where you have to move the whole thing to get to the A/V input the HPs5033 A/V input is on the side of the TV so you can disconnect and connect without the hassle.

Finally, the sound quality on this model is increased with the addition of the SRS Trusound XT. With this feature, no matter where you are in the room you get the same level of sound.

The TX-s27794 could be designed for consumers who are concerned about space. This compact 27-inch screen TV can fit many small or awkward positions in a home. And its size doesn’t take away from the sound and picture quality at all. In fact the TX-s27794 comes with the SRS HDTV system installed. This ensures you the level of sound anyone with a plasma TV has come to expect.

These are only a few of the models in the new HDTV line from Samsung. There are more to see and no doubt in the future Samsung will have a variety of models with new additions and features that will top what it has managed to do today. Samsung series 5- 5530 lcd tv

An Expert System Powered By Uncertainty

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.

An all new background for your myspace web page

Not many users of the Myspace are capable of creating the web page required to invite more number of visitors to the site. The best way is to rebuild the background on your own every alternative week. But if the user is not technology savvy and not really keen on experimentation, then the best way is to access resources on the Internet. There are plenty of sites that offer assistance in making the background a highly successful component of the Myspace web page.

By checking the popular search engines such as Google and Yahoo!, you can trace the resources that can help you work on the backgrounds of the myspace page. There are multiple options to download the various complex backgrounds for the Myspace page. The first and foremost option is the free downloads from popular sites. The second and not most preferred option by the youngsters is the paid backgrounds, which is issued against a license. In the paid option backgrounds, there are a number of rich features and color schemes. Under the paid backgrounds, the users have the option of customizing the requirements as per their desires and plans. Once the payment is made to the service provider, tools and software codes are provided to the Myspace user to download the data for the background from the Internet site. It is common for these providers to make the user-friendly. If the tools given to the users are not of their personal preference, the users can go their own way in terms of opting for the color schemes. The paid backgrounds have multiple options and are issued on the basis of license. There are numerous unlicensed backgrounds available on the Internet, but their reliability is a big question.

The backgrounds are widely available on the Internet for use and they run into thousands across all links. Go through them using the search engines and download the appropriate background. The Myspace page background is available in several formats. The two important among them are paid backgrounds and free backgrounds. The paid backgrounds are rich in features and sport a number of attractive features. Though the free backgrounds are also attractive and colored in bright schemes, the have limited options and user friendliness.

The free backgrounds can be installed on the web page as whole or set in the form of tiled manner. They can also be installed in multiple formats and schemes. Check various Internet sites offering the Myspace backgrounds and themes for additional information on their use. The color mix of the backgrounds is available in various choices. The users also have the choice of mixing colors on their own.

While mixing colors make sure that the background does not resemble a riot of colors. It could spoil the entire background apart from messing up the account. The primary objective should be to enliven the background of the account and not spoil it. Exercise restrain while choosing the colors. They have to be appropriate and relate to the profile of the account holder. Any slight deviation from the color choice could mean disaster to the account page.

5 Reasons To Purchase Desktop Computers

If you are in the market for a computer, there are a number of factors to consider.  Will it be used for your home, your office or perhaps even your home office combo?  First off, you will need to set a budget for your new purchase before deciding whether to shop for notebook or desktop computers.  Many offices use desktop computers because they are not intended to be moved around a lot.  In addition, affordability often plays a large role in someone’s decision as to whether to purchase notebook or desktop computers.

While you are shopping around, it’s important to keep in mind some of the benefits that go along with owning different types of computers.  To that end, this article provides five important reasons to purchase desktop computers.

- Desktop computers are typically much more affordable than notebook computers.  With notebooks, you are paying more for the convenience of portability.  For as little as $299.00, desktop computers can be purchased from one of the leading manufacturers and a notebook computer for as little as $499.00.
- Unlike notebook computers, replacing a keyboard, mouse, speakers or even a monitor does not require having your computer serviced by a professional repair shop.  Because notebook computers have everything built in, including the aforementioned features, it is more difficult to replace a keyboard or monitor as opposed to desktop computers, which operate on external connections.

- In the event of an unlawful entry into your home, desktop computers are not as likely to be stolen because of their weight and bulk.  Notebook computers, on the other hand, are small and portable.  This, alone, makes them more appealing to a thief than desktop computers.

- Desktop computers are stationary by nature.  Unlike a notebook computer, which can easily be moved from room to room, they are less likely to be dropped or broken because they are not moved as often.

- The vents on desktop computers are located on the back of the tower, which allows for proper ventilation that will help to prevent the computer from overheating.  Notebook computers, on the other hand, feature only one vent on the back with the remaining underneath the base.  If placed on a table, the air vents can become blocked and the computer may overheat.  If prolonged use leads to overheating, damage may result.

When choosing from the many desktop computers on the market, always make sure that you purchase from a manufacturer who has experience in creating computers.  Even though they are more affordable than notebooks, desktop computers are not cheap.  With an investment that involves several hundred dollars, you will want to consider the length of time the manufacturer has been in business, their reputation with customers and their warranty. 

Additionally, when choosing any system, including desktop computers, always look at the potential for future upgrading.  As you grow, you will want your computer to grow with you and a part of that will include a slight upgrade from time to time.  This is the only way to get the best use of your desktop computers and make sure that your investment is one that lasts for years to come.

Be Picky About Computer Keyboards

If there is anything I have learned in the past ten years of being an editor that is using my computer all day, it is that it is good and right to be absolutely picky when it comes to choosing computer keyboards. If this seems like an insignificant choice to you, then it is clear that you, unlike me, do not spend the majority of your days typing on a computer.

If you did, you would quickly realize what a difference computer keyboards can make to a typing experience. It took me a couple of years to realize that there were actuallly a lot of options when it comes to computer keyboards and that I didn't have to be satisfied with a computer keyboard that didn't fit my hands.

I have probably made my way through at least eight or nine computer keyboards in the past ten years. I have learned what suites my body and my needs better and that has often caused me to go on the hunt for a newer and better computer keyboard. I have learned that there are a huge variety ofAs computer keyboards and that if you search for them, they do not have to be too expensive or hard to find.

If you are about to purchase a computer for the first time, or if you are simply looking for a computer keyboard that fits your body and your needs better, then don't rush into a purchase until you have done some research to learn about your options. A great place to begin the search for computer keyboards or any other part of computers is by visiting a computer store where the employees are knowledgable about all things computer. Stop into a local store or two and see what you can learn about choosing computer keyboards that are right for you.

Another great way to do research on computer keyboards is online. That is, if you can manage to use your current keyboard for a few hours to do the research! Look through many websites until you find the deals that are in your budget and that match your needs. Finding a computer keyboard can be a tedious process, or it can be easy if you look in the right places. The bottom line is that if you are going to be using your computer a lot, then it pays to have the best possible computer keyboard.


All About Computer Viruses

our computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open.

You might have a virus.

Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?

Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive.

In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.

In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses.

A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.

When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.

This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.

Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)

These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.

As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser.

Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.

For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said.

But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus.

During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway.

Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk.

Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves.

Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states it’s “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer.

So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.)

On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses, they attack the machine itself rather than individual files.

Worms sit in your working memory, or RAM, Nachenberg said.

OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there?

Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program.

Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect.
This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said.

Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popups on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said.

There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place.

The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind.

For these other intentions, we first need to explain the “backdoor” concept.

The sole purpose of some viruses is to create a vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings.

Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said.

Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate.

Now back to the real viruses. Let’s say we have Joe Shmo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said.

OK, so the virus writers now control these computers. What will they use them for?
One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said.

That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could crack down on spam itself. Spam senders don’t want that.

Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers.

Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said.
