LED Benefits

Light-emitting diodes – once they were limited to simple indicators. Today they are so much more. Incandescent lighting is slowly replaced by these amazing creations of technology.

What makes these LEDs so important and why they promise to be so beneficial to you? This article is made to answer this question and let you glance at the face of technology today as it is.

For a long time LED's only visible color was red. And this was not the only thing limiting their use. Maybe this is why today there are still some manufacturers who keep their old habits on using the incandescent lighting.

The light made from a LED is not like the light made from incandescent bulb because it has only one color (wavelength) and one direction. This is a focused light source and it could be perfect for many applications like indicators but for too many others it's not so good.

It took some time for the LED designers to move around this obstacle but now there are two major solutions – multi-chip arrays and high-flux LED chips. These more advanced LEDs could achieve a closer effect to the one made from incandescent bulbs. That means that with this advancement LEDs are one step closer to the parameters that make the use of the old bulbs a need.

Some major advancement in the technology of LEDs provides the solution for any color you may need. The full visible spectrum of light could have been made as a LED: red, yellow, amber / orange till the cool looking vivid ultra blue. Even the white color is possible. Some time ago the developers of the LED technology believed that this will never be achieved. The new "doping" technologies increase LED light output by 20 times. That allows for the LEDs to be visible during day even in a sunny environment.

Let's take a look on what the incandescent light is giving us. We have a breakable glass package which could be a nasty hitch. Then we have a fragile inner body which life could have been shortened by a simple vibration. And finally the specialty of every incandescent bulb – 90% of the energy goes to heat.

With all these bad hints in mind let's proceed to the high efficiency of the LED technology with almost no heat generated during the process of energy transformation.

Some applications require colors. Let's compare the incandescent light and the LED technology regarding this use. The incandescent bulb will waste 90% off the energy on heat. In order for a color to be used a special filter should be placed in front of the light to filter only the color (wavelength of the light) we need. In the process 90% of the light is blocked by the filter. Simple math will easily show you that in the end you are using only 1% total efficiency for a colorful light made by an incandescent bulb. In the other hand we have the LED which will transform almost 100% of the energy directly to a one color light.

The truth is that what a marginal light source was before is not so marginal today. To see this for yourself examine the cars around you the next time you are in the traffic. Look for the taillights. Some of the cars are using a filtered red light from an incandescent bulb and some from red LEDs. See how more vivid the LED is in compare with the other one.

That's why today we could see on the market even standard LED lamps. And these lamps have it all – they are durable, daylight visible and a real blessing for every overworked observer.

It's time to look at a few indicators which will tell us more about LEDs. The first one is cost saving. For a facility of 1000 lamps after one year we will have approximately $ 3000 cost if we use incandescent bulbs. This is if we take in account only the major factor – the short life of these bulbs. But there are many other factors which are also important – the labor cost, power savings, operating downtime, incandescent bulb inventory and ordering costs.

The life time of the device is a very important criterion. LED lamps life is predictable and if they are used within their design parameters they will last around 10 years. One very important thing is that the life of the LED is not shortened when you turn them on and off. This however will not be true for the incandescent bulbs.

LEDs provide cooler operation. Taking in account the 90% losses on heat in the incandescent bulb technology this is not so hard to be accepted. But it's not just that. In the LEDs there is not filament that is heated for light generation. Their very design is not using the heat. Of course there is some heat dissipation in the LED body but it is far from the one in the incandescent bulb because there the whole idea is to generate heat and through this process – a light to appear.

Power consumption is another important parameter of every energy device. A standard 6S6 / 120V incandescent bulb use 50mA and its LED analogue is using 11mA. Almost 5 times lower power consumption means almost 5 times lower cost for energy every day. Do the math and you will see for yourself how much this efficient way of using the energy will help you reduce your costs per year.

One pretty nasty factor that comes with the incandescent bulb technology is called Cold Filament Inrush. This happens when the filament in the bulb is cold and you turn on the lamp. The lamp in this case will draw 10 times more current. If more lamps are powered simultaneously this will make a significant voltage surges which will shortly result in complete lamp failures. In LED lamps there are series resistors limiting the operating current. This will result in no current variations even if the very power grid is providing fluctuations. Some LED lamps have a shunt resistor too to bleed-off residual current.

In conclusion I should say that it is always up to you to choose what is best for you and everything under your control. LEDs are available and they could easily become your way of lighting things up.

Joe Rocket Motorcycle Jacket Review

Joe Rocket motorcycle jackets are some of the most popular in the industry. But are they worth the money? This article will give you a detailed look at Joe Rocket motorcycle jacket features in the terms of the criteria you should be using to decide which jacket you'll purchase.

Styling

Okay, this is a pretty vain criteria, but let's be honest. This is usually what attracts a buyer to a particular motorcycle jacket. If you do not like the way it looks, you probably are not going to buy it no matter how good it is, right?

Few would excuse that the styling of a Joe Rocket motorcycle jacket is second to none. From the classic black motorcycle jacket to the race team look, Joe Rocket has got you covered. There is a jacket for you no matter what your taste.

Protection

A nice looking jacket is all fine and good, but above all else, you are buying a jacket to protect you, right? You want to know that your injuries will be minimized in the event of a fall.

A Joe Rocket motorcycle jacket will protect you as well or better than any other jacket on the market. Most models include reinforced elbow / forearm and shoulder sections. This high level of protection, however, comes at a price … a high price tag and compromised comfort.

Price

These are some of the most expensive jackets on the market. A Joe Rocket motorcycle jacket will set you back between $ 100 and $ 500. You can usually find good deals on Joe Rocket motorcycle jacket online.

Comfort

Joe Rocket jackets are typically a little bit stiffer than other jackets. This is done to maintain the high level of protection that many riders desire. Most riders find this a little bit uncomfortable. With time, they loosen up a bit and become more comfortable, but still remain somewhat stiff. This is the main complaint about Joe Rocket motorcycle jackets.

Being somewhat thick, you can also get a bit warm inside these jackets. Fortunately, most models come equipped with a removable liner and air vents than channel outside air. Even with this feature, the jackets can get something hot.

Conclusion

We are talking about a sizable investment in your protection, no doubt about it. For your money, you get top quality protection and styling and decent comfort. You can find cheaper jackets, but be prepared to sacrifice some of that styling and protection. Understand where your priorities are and you'll know if a JR riding jacket is right for you. It is difficult to put a price on piece of mind when you are riding. In the end, each rider must decide for himself. Most riders (including this author) who have purchased one are glad they did so for the reasons stated above. Will you join this group of confident riders?

Snow in Alaska? — You’d Be Surprised

Does it snow in Alaska? Of course it does. But the reality of the snowfall amount that Alaska receives may be far different from the popular concept of snow in Alaska.

Many people conceive of Alaska as a barren land where it snows constantly in massive amounts and where everyone lives in igloos. Such a concept makes Alaska sound like a cold and white land.

In reality Alaska has more lakes, rivers, and green trees than does any state in the U.S. The state is intensely green and rich much of the year. But the rainfall total and the snowfall total may be much less than you may think.

Alaska Snowfall Totals

Here are some average annual precipitation and snowfall totals for a cross section of Alaska.

Anchorage — 15.37″ precip —- 69.0″ snowfall

Barrow ——- 4.67″ ———– 28.0″

Fairbanks —- 10.37″ ———– 68.0″

Homer ——- 24.93″ ———– 58.0″

Juneau —— 52.86″ ———– 101.0″

McGrath —– 16.18″ ———– 93.0″

Nome ——– 15.64″ ———– 56.0″

Valdez ——- 61.50″ ———– 320.0″

By comparison Buffalo, N.Y., receives an average of 80″ to 100″ of snow per year. Some sections of upstate New York, similarly affected by their proximity to the Great Lakes, receive an average of 150″ to 200″ of snowfall yearly. Hooker, N.Y., received 466″ of snow during the winter of 1976-1977.

Minneapolis, Minnesota, received their heaviest seasonal snowfall total of 98″ during the winter of 1983-1984.

As you can see from the Alaska totals above, most of Alaska is relatively dry, receiving less that 20″ of precipitation annually. The southcentral and southeastern coastal areas receive far greater precipitation.

Far northern Alaska receives precipitation totals typical of a desert. Notice Barrow’s annual total of only 4.67″ of moisture. Of course, most of that total falls in the form of snow. Due to the ice beneath the soil and the lack of intense drying sunshine runoff and evaporation are minimal. That’s why northern Alaska is not a dry desert despite the small amounts of precipitation.

Alaska Snowfall Records

It’s always interesting to hear about extremes and they can certainly be found in Alaska. For example, Thompson Pass, a popular extreme ski and snowboard area north of Valdez, once received a record 974.5″ of snow during the winter of 1952-1953.

Thompson Pass recorded 62″ of snow during one single 24 hour period in December, 1955. During February, 1953, Thompson Pass received a record 297.9″ of snow. That’s almost 25 feet of snow in just one month!

The deepest recorded snow pack in Alaska, and the deepest in all of North America, occurred at Wolverine Glacier on the Kenai Peninsula during the winter of 1976-1977. The depth was 356″. That’s packed, condensed snow. Almost 30 feet deep!

By comparison, Barrow, in the dry north, received a record minimum amount of snow during the winter of 1935-1936 of only 3″.

Here are a couple of other extremes for total precipitation. Montague Island in 1976 received a record 332.29″ of precipitation. That’s almost an inch of rain per day! On the other hand, Barrow received only 1.61″ of precipitation during all of 1935.

Alaska stores an immense amount of fresh water in its glaciers. An amazing 75% of the world’s fresh water is held in glaciers worldwide and Alaska holds more than its fair share.

Alaska has more than 5,000 glaciers, covering in excess of 100,000 square miles. Alaska has more glaciers than the entire rest of the world combined, excluding the ice fields of Antarctica and Greenland.

Valdez, the Switzerland of the North

Valdez lies on the southcentral coast of Alaska and receives an average of over 300″ of snow yearly. Typically, there are 6 foot drifts of snow on city rooftops. The canyon a few miles north of Valdez is home to several frozen waterfalls and makes Valdez a world-class destination for ice climbers.

Thompson Pass, further north of Valdez, boasts some of the best helicopter accessed extreme skiing and snowboarding terrain in all of North America. No wonder Valdez has been called “the Switzerland of the North.”

Each year Valdez holds a Winter Carnival. During the period of the 1990 Winter Carnival the year’s snowfall passed the 500″ mark. As part of the winter celebration the city showed the movie “Back to the Beach” on a 20 foot by 18 foot “screen” which they had carved from a snow bank. Talk about an outdoor drive-in theatre!

What is Snow?

Snow is crystalline frozen ice and the size and shape of the crystals depend on the temperature of their formation and the amount of water vapor present during formation.

Pure snow crystals are hexagonal, six sided. The basic water molecule consists of two atoms of hydrogen and one atom of oxygen and forms a triangle of three equal sides. During crystallization each new ice crystal bud is formed at a 60 degree angle. Crystallization continues until 6 of these triangles are complete. As the crystal falls through the atmosphere it becomes bigger and bigger and its six sided structure becomes the framework for more complex snowflakes.

Common forms of snowflakes include stars, needles, flat planes, columns, capped columns, dendrites, and irregular groups. Some snowflakes can be as large as 1″ in diameter.

For one of the most interesting human stories about snowflake research, consider that of Wilson Bentley. He acquired the nickname, “Snowflake” Bentley because he was the first person to photograph a single snow crystal in 1885. He studied over 5000 snowflakes and declared that no two snowflakes are exactly alike, a quote that has been passed on from generation to generation anonymously ever since.

In 1931, the year that Snowflake Bentley died, he published a book entitled, Snow Crystals. The book contained over 2400 of Snowflake Bentley’s images.

How Many Eskimo Words Are There For Snow?

It has been said that there are 52 words in the Eskimo, Inuit, or Yupik language for snow. It’s also been said that there are 21 words, and it’s also been said that there are over 400. Where does the truth lie?

The idea that since snow is so important in the lives of northern native peoples that there must be a multitude of words to describe it has attained the level of a myth. The truth of the matter is that there are probably about as many Eskimo words for snow as there are English words for snow.

Alaska Climate Changes

According to Alaska Senator Ted Stevens, “Alaska is harder hit by global climate change than any place in the world.” Global warming has been a trend for many years, but very few places show as many consequences of the trend as does Alaska. The average temperature has risen nearly 7 degrees in the past 30 years.

The changes due to a warming climate mean, for example, that the permafrost in Fairbanks and other towns is no longer permanent. Land has been slumping due to the melting permafrost and hydraulic jacks are needed on many buildings to keep them level. Further north, in Barrow, there are now mosquitoes where there once were none.

At the coastal village of Shishmaref increasingly higher water has been eroding away the land beneath the village buildings. The village may have to relocate further inland.

Spruce bark beetles have killed 4 million acres of white spruce forests on the picturesque Kenai Peninsula, the largest devastation due to insects ever experienced in North America. The beetles have been able to reproduce at twice their normal rate due to the higher summertime temperatures. The dead trees represent a huge fire hazard around numerous populated areas and prime recreational sections are threatened.

Glaciers have been receding at an incredible rate. Portage Glacier, south of Anchorage, has retreated so much in the past 20 years that it is no longer visible from the visitor’s center. Columbia Glacier on Prince William Sound is currently the world’s fastest moving glacier, retreating 80 to 115 feet per day. It has receded more that 6 miles since 1982.

There are still plenty of glaciers and significant snow in Alaska, but changes are occurring at an increased rate and will have worldwide effects.

Global Warming and Y2K

To earn a living, scientists or engineers must obtain funding for their projects. To get this funding, they are forced to become marketers and try to sell their ideas to their potential benefactors.

One good excuse for obtaining funding is to claim that at some future time a tragedy will befall the human race if something isn’t done about it now. As long as there is enough data being created to signal impending doom, the influx of funds will continue to the ones performing the research.

Impending doom is good for the media too. Reporters have a lot to talk about; the more they scare the public, the more attention the public gives the media networks, and the more advertising dollars they get.

Politicians have to get involved too. The more laws they pass to save the world, the more the media-conditioned masses applaud their efforts and insure their reelection.

Let’s look at what the media said would be a major tragedy, and how tens of billions of dollars were spent to avert it. The disaster never happened and lot of the money spent was wasted. This event should still be fresh in all but the youngest memories. It was labeled “Y2K” and ended just over seven years ago.

It came about because early mainframe computers were programmed using two digits to store the year instead of four. Thus “98” meant 1998 and “95” meant 1995. The older software would not know how to interpret “00”; it could mean 1900 or 2000. It was believed that some financial systems could crash if this problem was not corrected by the time the clock hit midnight bringing in the year 2000.

Many banks and financial institutions were aware of the problem and had it fixed or upgraded their software long before the end of the century.

With the help of the news media, “Y2K” turned into a serious business during the last decade of the twentieth century. Experts were often seen appearing on TV warning about the horrible things that would happen if every computerized device was not made “Y2K” compatible.

“Y2K” even made it to the movies. In the popular movie “Office Space” the main character, Peter Gibbons, was a “Y2K” engineer. “Y2K: The Movie” was a made-for-television movie released in late 1999 that depicted all the possible horrors that could occur because of “Y2K.”

In 1999, I was working for the Chicago branch of a Technical College as a systems administrator. This college had over eighty branches throughout the U.S. and each branch got its policy from corporate headquarters. I was in charge of maintaining over 300 computers, the majority of which were used as student laboratory computers.

It was early in 1999, when the corporate directive came. All computers in school had to be made “Y2K” compatible. I tried to explain to the school director that it makes no sense to upgrade student lab computers, since they are not used in production and most of the PC software that the students run already recognized the year 2000. The experts have told them that the ROMs (Read Only Memories) had to be upgraded.

On the newer computers I was able to download a ROM update and flash the ROMs. On older computers the ROM chips had to be physically changed. We had to get “Y2K” engineers to come and change the chips. This service cost thousands of dollars. What really irritated me, was that requests for things the students or instructors really needed were always denied, instead the corporate idiots spent their money on useless upgrades. Undoubtedly, they must have made all their eighty schools “Y2K” compatible.

As 1999 drew to a close, rumors of impending doom became more prevalent. The media kept emphasizing the possibility of riots. People were buying bottled water, wood stoves, and other survival gear, expecting the worse.

Then the new century rolled in, and nothing happened. It is estimated that 300 billion dollars were spent trying to make everything “Y2K” compatible. I would guess that only a small fraction of the total expenditure was really necessary.

I also have a consulting business, and none of computers I own were made “Y2K” compatible nor did I recommend that my clients make any “Y2K” upgrades. I have never seen a “Y2K” problem, nor has any client reported one.

Now let’s look at the present. In 2006 the former vice president and ex presidential candidate Al Gore released a documentary called “The Inconvenient Truth.” This documentary discusses a phenomenon called global warming. According to the film scientists are saying that the earth’s temperature is rising because of man’s carbon dioxide emissions. This rise in temperature can have cataclysmic effects on our world.

The film received an Academy Award for best documentary. This revived Gore’s career as a politician.

Experts are popping up throughout the world saying something must be done to avert disaster. The media has already assumed that most scientists agree that global warming is a reality and that we can expect dire consequences if we do not act.

Thus the new “Y2K” is born. This one can last more than ten years as long as the experts keep feeding the frenzy. Global Warming has now become a big business. As long as favorable data keeps being generated, the research keeps being funded and the media happily passes it on to the public.

The politicians are there to pass all the laws needed, no matter how ridiculous, to save the planet from impending doom. They can expect more votes from masses who have been thoroughly indoctrinated about the horrors of global warming from media propaganda.

Some scientists do not agree with the findings of the IPCC (Intergovernmental Panel on Climate Change), the United Nations group pushing global warming. They concur that currently the earth’s surface temperature is warming. However, they contend that solar activity data correlates much closer to the increase of the earth’s surface temperature than man’s carbon dioxide emissions. They also say that the computer models used to predict future disasters are based on incomplete data and can’t accurately foretell upcoming events.

I’ve seen the movie “The Inconvenient Truth.” Gore tries to illustrate his point by using a standard IPCC hockey stick curve, that many critics dispute. The majority of the movie gives examples of the bad things that are happening supposedly because of global warming. But if the major premise is wrong, then his examples of extreme weather are just events based on the unpredictability of climate change. The film feels like it’s more emotional than factual. It’s seems entertaining enough as a documentary to deserve the academy award.

The opposition has several films out. The best is called “The Great Global Warming Swindle (1hr 14min)” and is available on DVD from sellers such as Amazon.com. This film is much more informative than Gore’s documentary, since it gives a thorough and very convincing explanation of why global warming opponent scientists believe that atmospheric carbon dioxide levels do not influence climate change.

Global warming is being marketed pretty much like “Y2K” was in the late nineties. Even Hollywood is capitalizing on it. The opening lines of the movie “AI: Artificial Intelligence (2001)” predict the melting of polar ice caps due to greenhouse gases and the flooding of cities like New York. More recently, “The Day After Tomorrow (2004)” predicted massive climate change because of unabated global warming.

I think that the scientists who oppose global warming present a much better case than the ones for it. But because global warming is “politically correct” these days, the opposition is largely ignored or accused of being paid by oil companies in order to sabotage the “inconvenient truth.”

Is My Computer Security System Safe From Attack?

Dear Fellow Business Owners:

Do you know that thousands of websites, such as yours. are hacked on a daily basis? You might not even be aware of it unless the hackers chose to leave evidence. Maybe they did not because they like being able to return at will. And be inside your site! Inside your business! Prowling and searching and taking.

Every day, business owners lose sensitive data, money, or incur irreparable damage to their reputation due to security vulnerabilities in their computer security systems and websites. Malware is only a part of it. You are most certainly vulnerable in more than one area of your system, if you know it or not. The only question is what, if anything, you are going to do about it.

Outdated content management systems, poorly coded plugins or design flaws are just some of the vulnerabilities hackers can exploit to gain unauthorized access to your site and, from there, access your private databases and modify your site’s pages to, for example, load viruses onto your visitors’ computers or display illegal or offensive content. And I haven’t even mentioned the more destructive and exotic types of malware here.

Unfortunately, hiring a cybersecurity company to perform a security audit of your computer system can be extremely expensive, often costing several thousand dollars. But you may already be aware of this. And I’ll bet you’re also smart enough to know how much it will cost you personally to just ignore it.

You can instead obtain your own security, without having to hire people you don’t know to go into your private systems. And by doing it yourself, you can be sure what is and what is not included. One way to establish cyber security safety is to begin to plug the gaps, and obtain what is needed most today, and get the rest over a period of time that you designate.

This is not all or nothing today. You can build a safe system over time.

By taking charge of the process yourself, you will always know where you are in your quest for cyber security.

If you are adept enough to operate your own computer systems, then you can certainly take charge of this process. You can download the entire process yourself. Or possibly you might prefer to have someone you know and trust to take it over process, but with you monitoring the every step of the way.

Either way is fine, at least you are taking action.
