Uninterrupted Power Supply

by

Uninterruptible power supply, more commonly recognized as UPS is an electronic apparatus that acts as a back-up power supply unit for a prescribed time of time when the electricity supply is disrupted or when the line voltage varies abnormally. UPS has gained importance as it is badly needed to provide back-up power supply to computers. People more often than not do not attach much importance to power protection or backup power supply till they suffer loss of valuable computer files or worse, equipment damage during electricity breakdown.

To obtain uninterrupted power supply, you require to convinced add-on items similar to an energy storing backup battery, an AC-DC charger and a DC-AC inverter. There are three main types of UPS power backup devices available in the market. They are known as Standby or Off-Line (SBS), which is the basic model and of the lowest grade; Line Interactive (SBS), which is the intermediate model and of the middle grade; On-line which is of the highest grade. All of them use battery backup when the input power supply fails, but under normal conditions these three units handle the power differently. Of these three basic design types, each offers more power defense than the lower grades.

Standby UPS includes a transfer switch and its purpose is to switch the load to the battery / inverter should the AC power source fails. The transfer time is usually between two to 10 minutes depending on the amount of time it takes to detect the lost utility voltage and turn on DC-AC inverter. Due to this delay, the power to the load is during this period is interrupted. The equipment’s power supply should understandably have more hold up time than UPS transfer time to avoid loss of data. Generally, a power factor corrected SMPS of a personal computer has at least 10 to 20 ms hold-up time. Since the inverter operates in standby mode and starts up only when input power fails, the SPS has the highest efficiency and reliability. This is the least costly UPS and hence the most common backup type used for PCs.

Line Interactive UPS under normal condition evens out and to a certain degree regulates the input AC voltage through a filter and a tap-changing transformer. The bi-directional inverter/charger is always connected to the output of the UPS and consumes a portion of AC power for charging the battery. When the input power fails, the transfer switch disconnects AC input and the battery/inverter provides output power. It is said its rate of efficiency is quite high at 90 to 96 percent.

Dell to offer Ubuntu Linux on some computers

Wednesday, May 2, 2007

Dell Inc. (Dell) announced Tuesday that, due to public demand, they will be offering an alternative to Microsoft Windows on a selection of their desktop and laptop computers. Dell will partner with Canonical Ltd. to pre-install the recently released Ubuntu 7.04 distribution of the Linux operating system.

Until recently, Linux distributions have not been adopted by mainstream computer makers due to concerns over ease-of-use. Newer distributions, such as Ubuntu 7.04, have become much more user-friendly, with features such as automatic updates and software installation.

Ubuntu director of business development Chris Kenyon told the BBC that one of the reasons Ubuntu was selected was its support features and hardware compatibility. “Dell are going to work with us to make sure Ubuntu works fully on its hardware,” said Kenyon. A Dell representative suggested that the Ubuntu distribution was chosen due to public demand as expressed on a Dell-run forum website, IdeaStorm. “It was overwhelming, the response we got to the survey,” said Jeremy Bolen, a Dell spokesman.

Tuesday’s announcement was not the first for Dell’s Linux offerings. They have offered servers and workstations with an optional enterprise version of Red Hat Linux for some time now. The chairman and CEO of Dell, Michael Dell, is reported to have Ubuntu installed on his own laptop.

Perry Donham, an analyst with Aberdeen Group of Boston, suggested that the Dell-Ubuntu partnership will benefit Ubuntu more than it will Dell. “It’s going to be a small part of [Dell’s] market,” said Donham. “But it’s a great win for Ubuntu and for Linux in general.”

Dell indicated that the Ubuntu-based computers would be available in the next few weeks, from Dell USA only for the time being. The pricing structure has not been revealed, or when such computers would be available in countries other than the United States.

Mars rover engineers build test sandbox

Sunday, May 8, 2005

Mars rover engineers have built a test bed simulating the condition of the Mars Rover Opportunity, which became stuck in a Martian sand dune on April 26. The test bed uses a combination of materials including play sand for children’s sandboxes, diatomaceous earth for swimming pool filters, and mortar clay powder.

Opportunity dug into soft sand to wheel-hub depth as it drove over a dune about one-third meter (one foot) tall and 2.5 meters (8 feet) wide. “We’ve climbed over dozens of ripples, but this one is different in that it seems to be a little taller and to have a steeper slope, about 15 degrees on part of its face,” said Mark Maimone, a Jet Propulsion Laboratory (JPL) rover mobility engineer. Tests will be conducted using an Earth-bound twin of the rover and the simulated Martian dune to determine how to best maneuver Opportunity out of the predicament before transmitting commands to the actual vehicle.

“We choose to proceed cautiously, so we don’t expect to begin actually driving out of the dune before next week, possibly later,” said Jim Erickson, rover project manager at JPL. “Both Opportunity and Spirit have already provided many more months of scientific exploration than anyone expected. By taking good care of them, we hope to keep them exploring for more months to come. Tests so far have sustained our optimism about Opportunity’s ability to drive out of this dune, but we have more testing ahead to understand how robust that capability is.”

Engineers constructed a simulated dune last week using sand that was already at JPL’s rover testing facility and put a test rover into a similar dug-in position. The test rover had no difficulty driving away, even when sunk belly-deep. However, that sand offered better traction than the finer, looser material that appears to make up the surface at Opportunity’s current position. “We needed to do tests using material more like what Opportunity is in, something that has a fluffier texture and cakes onto the wheels,” said JPL rover engineer Rick Welch, who is leading the tests.

Based on images of wheels and wheel tracks from Mars, Dr. Robert Sullivan of Cornell University, a rover science team member, working with engineers in the JPL test bed, helped match the properties of the test sand as closely as possible with those of the sand beneath Opportunity, “We found that when the wheels dig in, the material we’re using does stick to the wheels and fills the gaps between the cleats, but it doesn’t stick when you’re just driving over it. That’s good because it’s the same as what we see in the images from Opportunity,” Sullivan said. Experiments show that the test rover, after some initial wheel-spinning, can drive out of the more powdery material.

The team went to several home supply and hardware stores to find enough bags and boxes of the ingredients to make more than 2 tons of the simulated Mars sand for the more realistic mobility tests, according to JPL rover mobility engineer Jeff Biesiadeckia.

IEEE approves 802.11n standard after six years

Posted by 5uSsM9 | Posted in Uncategorized | Posted on 20-03-2017

Saturday, September 12, 2009

On Friday, the Institute of Electrical and Electronics Engineers (IEEE) ratified the next generation of Wi-Fi Alliance certification known as 802.11n. The path to ratification began on September 11, 2003 with 11 major drafts of the specification over the course of six years. Even though just approved, wireless devices have been available on the the market for over two years, running on what is known as “draft n” or “pre-N”.

The 802.11n standard operates on both the 2.4Ghz and 5.0Ghz frequencies. This will allow it to be backwards compatible with 802.11a, 802.11b and 802.11g, provided that the base station has dual radios. The speeds of 802.11n are substantially faster than that of its predecessors with a maximum theoretical throughput of 600Mbit/s.

Very few additions were made to the 802.11n draft standard over the last two years, so most if not all “draft n” hardware available on the market today is expected to be compatible with n-standard devices available in the future. In a similar process of the upgrade from “pre-G” to 802.11g, it is expected that most manufacturers of wireless hardware will release new firmware to bring all draft devices up to full standard compliance.

Skin Care For Acne Pimples

by

Johnathon Lennox

Caring for your skin is crucial for superior health and beauty, but certainly so when you are susceptible to pimples. One of the best ways to keep acne under control is to maintain your epidermis\’s health as a lot as possible. This means keeping skin clean and protecting it from damage from sun light and harsh make-up.

Cleansing Your skin

Clean your face twice a day with a gentle soap or special pimples skin cleanser, making use of a gentle, circular motion of the fingertips. Don t scrub, since this might irritate acne pimples. Moisten the face with warm h2o, then put on cleanser from the hairline to the neck. Rinse with lots of water and pat dry with a soft towel.

Those with specifically oily skin might need to have to use an astringent, but it must be alcohol-free, and used with care. Put on it only to the oiliest parts of the facial area and discontinue use immediately if your epidermis becomes irritated. In case you feel you need an astringent, you may need to have to see a health-care professional as a substitute.

Hair care can also be crucial — shampoo twice a week to as often as day-to-day, keeping the shampoo away from your facial area as very much as feasible.

Shield Your epidermis From The sunshine

A suntan might dry your skin, making the acne pimples less noticeable, but this is only temporary. As your epidermis becomes accustomed to sun s rays exposure, the acne will flare up again. Meanwhile you are risking epidermis damage that could trigger premature aging and epidermis cancer. Many medicines that treat acne pimples cause the skin to become more sensitive to sunlight and more vulnerable to burning. Whatever the weather, you should wear sunscreen on your facial skin and any other exposed epidermis when outside.

Choose Makeup With Care

The ideal decision for very good acne pimples epidermis care is to wear no makeup at all. But if you feel you must wear makeup, choose products labeled noncomedogenic — that means they will not block your pores. Be mindful that these goods may still cause pimples in some individuals. Above all, stay clear of makeup with an oil base. Read the labels carefully and use sparingly.

Shaving

Try the two electric razors and safety razors to see which causes the least aggravation to epidermis spots. Always use a sharp blade in a safety razor — change the blade every 2 or 3 shaves. You may have to shave around spots to avoid cutting them. Be sure to soften the beard as very much as possible with warm water and shaving cream before starting. If your skin is covered with blemishes, perhaps it is best to skip shaving that day.

No Touching

As tempting as it might be to squeeze pimples, don\’t! That invites more trouble by spreading the unhealthy bacteria which trigger pimples. It could also lead to permanent skin damage.

Try to keep away from touching your face as a lot as feasible because the hands carry dirt, oil and germs.

Rest assured that acne might be brought under manage. Remedies will go a long way toward clearing your epidermis of acne. Your job is to help the healing practice along as a great deal as possible by taking very good care of your skin.

Homes of six Minnesota politicians vandalized

Posted by 5uSsM9 | Posted in Uncategorized | Posted on 17-03-2017

Tuesday, October 28, 2008

An unknown person or persons wrote graffiti and vandalized the exterior of homes belonging to six members of the United States congressional delegation from the state of Minnesota late last Monday night or early Tuesday morning.

According to the Star Tribune, Laurie Coleman, wife of U.S. Senator Norm Coleman, found the words “U R A CRIMINAL, RESIGN OR ELSE! PSALM 2” written on the family’s garage. The word “SCUM” was also written in three places on another side of the garage. Psalm 2 is a biblical reference.

The homes of senator Amy Klobuchar, and U.S. representatives Michele Bachmann, Keith Ellison, John Kline and Jim Ramstad were also targeted by vandals. Ellison’s house was the only one that sustained damage.

We’re looking at this as an actual threat.

Peter Panos, St. Paul Police spokesman, told the Star Tribune that threatening message in the graffiti were cause for concern.

“We’re looking at this as an actual threat,” he told the Star Tribune. “We’re taking it quite seriously. Vandalism threats are pretty rare in this city.”

Bachmann, Coleman, Kline and Ramstad are Republicans. Klobuchar and Ellison are Democrats. All live in the Minneapolis-Saint Paul metropolitan area. Reps. Collin Peterson and Jim Oberstar, who live in out state Minnesota, along with Rep. Betty McCollum — who lives in a condominium, did not receive vandalism to their homes. Senate candidates Al Franken and Dean Barkley, who are running against Coleman in the November elections, condemned the vandalism.

There’s no place for this unacceptable behavior in our political process, or in our communities

“There’s no place for this unacceptable behavior in our political process, or in our communities,” Franken’s campaign told the St. Paul Pioneer Press. The paper said that the Franken campaign office was the victim of graffiti attacks including the words “Crazy” and “No New Taxes.”

Federal and local authorities are still investigating these incidents, as well as similar incidents that took place in Missouri.

Over the weekend, a Minnesota hair salon was targeted. Police say it may have been a copycat vandal, though the salon is said to be patronized by Norm Coleman.

French police arrest two women wearing veils after burqa ban goes into effect

Posted by 5uSsM9 | Posted in Uncategorized | Posted on 17-03-2017

Tuesday, April 12, 2011

One day after France began enforcing a ban on the public wearing Islamic veils that cover the face, either a niq?b or a burqa, French police briefly detained two veiled women. The police later claimed that the women were arrested for taking part in an unauthorized protest, not because they were wearing veils.

The new law is hotly debated. The women were arrested while outside the famed Notre Dame Cathedral in Paris, and may now face fines of up to $217 (150 euros), community service and/or a citizenship course under the law.

While the ban covers the burqa and the niq?b, it does not include the hijab or the chador. The hijab is a veil that leaves the face visible while covering the hair and neck, and the chador covers only the body.

The French Republic lives in a bare-headed fashion…

The law has stirred much debate, both in France and around the globe. Those who oppose the new law say it limits freedom of speech and freedom of religion, while supporters claim that women are degraded by wearing veils and the law is intended to empower those women, as well as increase public security.

The French government, in defense of the ban, said that it was necessary because wearing veils falls short of the living standards in France and and makes women be of an lower status in a country where everybody is considered equal.

French Prime Minister Francois Fillon has said that the ban is consistent with the national values of France. “The French Republic lives in a bare-headed fashion,” he said in a statement published by a government newspaper.

The French government previously made efforts to accommodate Muslims in the country, including establishing a council dealing with the presence of Islam; however, according to Amer Sahar, a professor who studies the topic, some Muslims in the country say that they feel as though they are under assault by the government. She said that some are “resentful of the fact that they are not allowed to be both Muslim and French.”

The French government is also concerned with women and children who are forced to veil themselves. It has said that such an action is “a new form of enslavement that the republic cannot accept on its soil.” There is a fine of 30,000 euros (about $43,300) and a year in prison for forcing an adult to wear the niq?b or burqa. The fine is doubled for forcing a minor to wear the veils.

Activist Rachid Nekkaz auctioned one of his homes to provide money to pay the fine for any woman arrested under the law. “I would like to send a clear message to President Nicolas Sarkozy that we can do what we want. We have rules. We have a constitution and everyone has to respect it,” he said.

According to the French Constitutional Council, the law “conforms to the Constitution” because it does not limit the freedom of religion or excessively punish people for exercising that right in a place of worship.

South Carolina governor Nikki Haley endorses Mitt Romney for U.S. president

Saturday, December 17, 2011

South Carolina governor Nikki Haley endorsed Republican Party (GOP) presidential candidate and former Massachusetts governor Mitt Romney yesterday at an event in Greenville, South Carolina. According to The Washington Post, the widely-sought support of the Tea Party-backed Haley reflects a softening of conservative concerns about Romney, who is considered a moderate in the race. He currently trails former Speaker of the House Newt Gingrich in South Carolina, which will hold its primary election on January 21.

Haley, who is of Indian descent, is the first female governor of South Carolina. She is considered a possible 2012 Vice presidential nominee and potential 2016 presidential candidate. She said that while there is not a “perfect candidate” for the 2012 race, Romney is “a leader that knows what he wants to do the first day he gets into office.” Haley’s belief that Romney will repeal Obamacare ultimately led to her support.

Romney has remained consistently high in polls since entering the race earlier this year, but has not been able to solidify conservative support, due in part to the view that the health care reform he instituted in Massachusetts was similar to Obamacare. Recently, Newt Gingrich has risen in the polls as the latest anti-Romney candidate, but has come under attack for providing consulting service to Freddie Mac. Gingrich holds a double-digit lead in South Carolina.

According Steve Schmidt, an adviser to John McCain’s 2008 presidential campaign, Romney has “weathered a turbulent period and seem[s] to have regained equilibrium in the context of the Gingrich surge.” However, Gingrich supporters do not give much credence to the Haley endorsement: state co-director Leslie Gaines commented, “We have the whole Tea Party support which got her elected.” As a state legislator, Haley also endorsed Romney in 2008.

Haley and Romney are currently on a two day campaign tour of South Carolina on Romney’s plane, which his wife Ann refers to as “Hair Force One”.

The Deadliest Fall

Posted by 5uSsM9 | Posted in Uncategorized | Posted on 14-03-2017

18 December 2004

Emergency hospital during 1918 influenza epidemic, Camp Funston, Kansas (source: National Museum of Health and Medicine, AFIP).

A bout of the flu can be mild. In young, healthy adults, many infections pass unnoticed. But sometimes the influenza virus evolves into a strain that decimates its victims. The worst known strain swept the world in the Fall of 1918, infecting 500-1000 million and killing 40-100 million, about 2-5% of people.

There are several theories about where the pandemic began, but the likeliest origin was in Haskell County, Kansas, in the United States. People in the sparsely populated county, where farmers raised pigs, poultry, cattle, and grain, began suffering from influenza in late January 1918. Unusually for flu, it was young, healthy adults who were hardest hit. Victims fell ill suddenly, many progressing to pneumonia and dying, often within days. Within weeks, however, the epidemic ended. The natural geographic isolation of this community normally might have contained the fatal flu in a sort of unintentional quarantine, but the First World War intervened. Men were uprooted from their home towns and congregated in huge numbers in army camps for training and then shipping out to other camps or to fight in Europe. The destination for men from Haskell County was Camp Funston, part of Fort Riley, Kansas, where the first influenza case was reported in early March. As soldiers moved among camps, the virus spread. Within two months, the epidemic spread to most of the army camps and most of the largest cities in the United States. As American soldiers went to France, so did the virus, spreading first from the port of Brest.

The flu then spread worldwide. The pandemic reached its height in the Fall of 1918. Spain was affected early, and because Spain was not fighting in the World War, there was no wartime censorship, and news of the outbreak became widely known, leading to the flu being called the Spanish Flu in many countries. In Spain, however, it was called French Flu or the Naples Soldier. In India, about 12 million people died of flu. In some US cities, people died so quickly that morticians couldn’t cope with the bodies. According to Jessie Lee Brown Foveaux, who worked in the Fort Riley laundry during the epidemic: “They were piling them up in a warehouse until they could get coffins for them.”

The disease started with cough, then headache. Temperature, breathing and heart rate increased rapidly. In the worst cases, pneumonia came next, the lungs filling with liquid, drowning the patients and turning them blue from lack of air. Patients bled from every orifice: mouths, noses, ears, eyes. Those who survived often suffered temporary or permanent brain damage. Several million developed encephalitis lethargica, in which victims were trapped in a permanent sleeplike and rigid state, as portrayed in the 1990 movie “Awakenings.” In others, normal thought processes were impaired. During negotiations to end World War I, US President Woodrow Wilson was struck with flu, and people around him noted that his mental abilities never fully recovered. The French leader George Clemenceau had wanted harsher punishment of Germany than Wilson had desired. Clemenceau may have convinced Wilson in his weakened state to accept such harsh terms, which may have been one of the factors causing World War II.

Since flu is highly contagious early in the illness, even before symptoms appear, strict quarantine may be necessary to stop its spread during an epidemic. Australia kept its 1918 flu death rate relatively low by enforcing quarantines. However, in many parts of the world, public health officials hesitated to impose such measures, giving the disease time to gain a foothold. In the US city of Philadelphia, a rally of half a million people was planned in September 1918 to sell bonds to fund the war, at just the time when the flu started to infect residents. Although doctors warned the public health director to cancel the rally, he wanted to meet the city’s quota to raise money for the war and refused to cancel the event. Within days after the rally, half a million city residents caught the flu.

Why was the 1918 flu so deadly? The influenza virus wasn’t preserved at the time of the outbreak, at least on purpose. But in the late 1990s researchers Ann Reid, Jeffery K. Taubenberger, and their colleagues extracted and sequenced the genetic material of the virus, RNA, from tissue of victims who died in the pandemic. They used bits of lung that were preserved in formalin from victims on army bases or from victims buried in permafrost in the Alaskan village of Brevig Mission, where flu killed 85% of adults. Comparisons with known flu viruses in humans, pigs, and birds suggest that some genes of the 1918 virus came from birds or an unknown animal source. Other scientists then were able to show that the amino acid sequence of hemagglutinin protein from the 1918 virus had several changes from other flu viruses that may have helped it to easily bind and invade human cells, and that made the virus look different enough from earlier flu virus strains that people had no immunity.

The possibility exists that another flu pandemic will sweep the world like the one in 1918. In 2004, an H5N1 influenza virus has killed millions of birds and at least 30 people in southeast Asia. So far this virus strain has not evolved the ability to pass directly from human to human, but that possibility becomes more likely as the bird flu pandemic continues and humans remain in contact with chickens, ducks, and other birds. The virus has killed two-thirds of people reported to be infected. Dr. Tim Uyeki, an epidemiologist for the US Centers for Disease Control, says, “you have the ingredients in Asia right now for a public health disaster.”

But since sequences of this bird flu virus are known, it may be possible to develop a vaccine or set of vaccines to protect against it. At a special meeting of influenza experts on November 11th and 12th, World Health Organization influenza program chief Klaus Stohr said, “It is not only possible, but also important, that influenza pandemic vaccines be made available… and there’s a shared responsibility needed to make that happen…. We have a huge window of opportunity now.”
