Dark energy is described as the biggest puzzle of our universe. This mysterious force, discovered in 1998, is pushing the universe apart at increasing speed and astronomers developed a new method of measurement. Using NASA’s Hubble Space Telescope, astronomers were able to use a giant magnifying glass in space – a massive group of galaxies – about the nature of dark energy. Their calculations, in combination with data from other methods, a significant increase in precision measurements of dark energy and can eventually lead to explanations of phenomena is really hard to achieve.

Although scientists do not know what dark energy, you know what a big part of our universe – around 72 percent. Another piece, 24 percent is supposed to be dark matter, mysterious character, but also easier to study dark energy, due to the influence of gravity in this case, we can see. The rest of the universe, only four percent, the substance that makes people, planet, stars and everything from the atom.
Cosmic Lens

In his new study, researchers used the Hubble images on the massive group of galaxies called Abell 1689, which acts as a lens or gravitational lensing studies. Gravity causes clusters of galaxies behind the image several times in distorted forms, something like a house mirror that distorts the face of laughter.

Using these distorted images, the researchers were able to figure out how much light, the background galaxies group bowed – a feature that depends on the nature of dark energy. His method depends on accurate measurements of the Earth’s distance and velocity of the background galaxies are traveling away from us. The team used this information to forces of dark energy that is causing our universe to accelerate quantified.

“What I like is that our new approach is very visual,” says Eric July, astronomer JPL, Pasadena, Calif. “You can literally see the gravity and dark energy buoy in the background images of galaxies in the arches.”

According to the researchers, the method requires several steps carefully. They spent recent years developing mathematical models and specialized map of the exact problem – and the dark and “normal” – the cluster Abell 1689

“Now we can give you a technique that is used for other gravitational lenses,” says co-author Priya Natarajan, cosmologists at Yale University, New Haven, Connecticut “We are a strange phenomenon of nature is used to learn more about the role of dark energy in our universe.”

“We need dark energy problem from all sides,” he said in July “It is important that the different methods and we now have a new and very powerful.” July is the first author on the study results are included in the 20 August issue of the journal Science.

Deserts are obvious places for solar installations. Land is cheap and plentiful sunlight. Unfortunately, so is the dust, dirt and wind, leading to contamination of the solar panels that could be a big hit in effectiveness. Send a man with a tractor wheel in the heat, does not sound like the best job in the world and self-cleaning systems depends on the water is not always possible in areas where clean water is difficult to obtain. Another solution is ruixada with independent panels, which is treated with electric charge, such as solar panels. Solar panels are scattered on the technologies developed for other conditions, dry and dusty – Mars.

This technique involves placing a transparent system, electrically sensitive materials stored in transparent glass or plastic film panels. Sensors to control dust on the surface of the material and energy of the console, the concentration of dust in the critical level. electrical charge sends a mixture of wool to repel dust in the material surface, dust and remove the right edge of the screen.

Within two minutes, remove the process from 90 percent of the substance is deposited on panels and require only a small amount of electricity panels for cleaning.

“We believe that our self-cleaning panels used in areas with high concentrations of dust and particulate emissions will be very useful systems, solar energy,” Study leader Malay K. Mazumdar, Ph.D., “he said. A layer of dust collector session ounce yard conversion of solar energy by 40 percent, “says Mazumdar. “In Arizona, the dust deposited every month, about four times. The delay is even greater in the Middle East, Australia and India.”

Mazumdar, a Boston University, said that the need for technology is increasing the popularity of solar energy. The use of solar or photovoltaic panels increased 50 percent for the period 2003-2008, and forecasts indicate growth of at least 25 percent annually in future.

“Our technology can be used in small and large solar energy systems. To our knowledge, this is the only technology to automatically clean the dust that does not need water or mechanical movement.”

Working with NASA, Mazumdar and his colleagues developed a self-cleaning solar technology for use on the moon and Mars missions. “Mars is naturally dry and dusty environment,” said Mazumdar “solar panels and energy and Rovers future manned missions, the robot must not succumb to corruption. However, even solar panels in the world.”

This market size for solar panels is 24 billion U.S. dollars, said Mazumdar. “Less than 0.04 percent of energy production in the world comes from solar panels, but only four percent of the desert in the world dedicated to the harvest of solar energy, our energy needs are respected in the world. This self-cleaning technology can play an important role .

The team benefits from the self-cleaning coating described in the report at 2:40 and the National Assembly of the American Chemical Society (ACS).

Pargas art is no longer satisfied with a point and shoot compact camera only to point and shoot. They want cameras with multiple functions that can produce crisp, clear images, even if we were a little unsure of our approach to photography. We want a wealth of creative way of shooting, and those weak attempt to transform it into something particular. I want high definition video. Canon introduced a trio of updates and all Powershot offers much more. Among the specification enhances high-definition video up to 1080p resolution, the team of sensor, lens, image enhancement and maintenance of memory cards SDXC.

The first of the new Canon PowerShot offer the same 3-inch LCD, 3.8 x optical zoom with autofocus, ISO80 ISO 3200 and manual handling of the S90 ring as before. SA and sports system in which the patient remains constant SA high sensitivity. System DIGIC 4 image processor and 10-megapixel CCD sensor to work together and destroy to reduce noise and improve image detail with high sensitivity settings to help.

X 2.30 x 3.93, but 1.16 inches S95 is equipped with 720p video recording with stereo sound, and is the first Canon to build the sport in high dynamic range functions, which made three shots rapidly through various positions and then in combination better image. He is also the first PowerShot to use the image stabilization of hybrid technology, which says that both corrections and change of angle of vibration of the camera to compensate for different types of traffic used.

Consumers are offered around 200 pictures of battery charge and can now enjoy a large screen and media card formats SDXC.

In the PowerShot S95 will be available in late August and will sell for about the price of U.S. $ 399.99
PowerShot SD4500 IS

SD4000 is a feature-rich was discovered several months ago and now is the next incarnation of the Canon. E SD4500 has the same retro-illuminated CMOS 10-megapixel sensor and three-inch LCD of its predecessor but now has a 10x optical zoom with optical image stabilization.

The new chamber will be high definition movies with stereo sound upgrade to 1080p. Moreover, there is now a way of super-slow motion, given that the film is 240 shots per second, albeit lower resolution of the action scenes of the Matrix-like home videos and Add dynamic stabilization services image.

Back to panteixos face the camera and the best selection of photographs, including five consecutive frames and select the best pictures, “based on the movements and expressions.” As above S95 is Canon SD4000 HV system, but special attention is a picture after dark night scene with the addition of a party which reduces the vibration of the camera, allowing users to “shoot beautiful images in the dark.”

Available in early September, SD4500 IS sells for U.S. $ 349.99
PowerShot SX130 IS

With 4.46 x 2.88 x 1.80-inch size, SX130 IS is slightly stronger than SX120 is before him, but I need space for new 12 megapixel CCD sensor and 12x optical zoom with their own productions, optical Image Stabilizer. Like its predecessor, the new camera is equipped with 3-inch 230,000 points, ISO sensitivity of ISO 1600 ISO80, is said to be good for 130 pictures on a single charge and has an ingenious “P / A / S / M setting controls the upper of the chamber. but 720p video recording at high definition stereo sound and mid SDXC cards.

If you are a fan of military strategy game of risk, so it would definitely interested in this: October 13th, Bonhams auction house in London will sell “very rare” copy of the game of war, military complex board game comes from the 1890th Unlike risk, which is played for fun and for a surplus of friends throw a game of war was designed to make the game truly military officers to train for WWII. It was based on Kriegspiel, war game invented by Lt. Georg von Reiswitz the early 19th century, the education officer in the Prussian army. If you wish, but they need to stop the ATM on the way there – The game is expected to bring between UKP1, 500-2000, or U.S. $ 2,330 to $ 3,100.

The game is played on the map were in the range of six inches per mile, the troops showed little blocks of slate, army blue, the other red. At that time, the tactics have changed little since the Franco-Prussian War of 1870, as evidenced by the inclusion of horse cavalry and artillery units in the game. Machine gun units are also included, but only six of them. Probably the designers did not expect the majority of the guns finally defeated in World War I

Description obtained from Bonhams described as a package, “mahogany box (with key), which consists of 600 red and blue slate tile infantry, cavalry, motorized infantry, artillery, horses, engineers, and machine gun units, two masters of ivory, two compasses, two Ivory scales two copper bowls, two pieces of ivory, a pair of pliers or ‘foxes’, shaking red leather, yellow, red and blue bars and wooden ruler. ”

Buyers will also be a letter of authenticity from the National Army Museum, a copy of the manual. If you’re planning an intimate one-on-a-night game, however, aware that few other people will be needed. According to the manual, it is necessary to use two officers to the commander of enemy forces, subordinate officers in the units of the importance of central authority, the judge, two assistant representatives arbitrators command and officer of progress record business magazines, it’s time to send and receive messages and losses.

It seems that a little strange while driving along the road back into the night, away from all known sources of electricity when it suddenly came to work the street. Such things are possible, however, and even common. This is because the light of science groups are now engaged in the production of solar LED street lights, which are completely independent of local authorities to implement. Although electricity is not a problem, lighting Science of countries which are lighter, more efficient and requires less maintenance than regular street HID. This argument, of course, someone who feels like a fresh series of lane street now installed on 23-kilometer (14 mile) stretch of elevated highway in Mexico City viaduct Bicentenario.

Lighting Science says that his 100-watt, 5000K gallery are at least 50 percent more than the product. Candles must be running on low voltage DC source into electrical energy that can come from either solar or wind energy.

It also said that the intense and uniform light distribution policy, it should also save thousands of dollars in more than 60,000 hours of standby life support. Is it because they do not need to replace the bulb or reballasting a direct line cords for beginners and capacitors. If you need maintenance, electrical components are accessible through the swing doors, which is not the necessary tools to open. Minimal maintenance was a major reason why have been selected by BHP Billiton Energy of Mexico.

Since the lights are publicly traded, operating temperatures from -40 to 40 ° C is (-40 to 104F), it will be interesting to see how the maintain the often intense heat in Mexico City.

The message is clear. Whiskey and management is not a good mix. But rules must be broken and researchers Napier University in Edinburgh has managed to successfully marry the two, but as fuel, not the driver. Scientists have two by-products, whiskey, and the labor market and converted into energy-rich biofuels, which require vehicles to undergo changes before use.

The technology behind the development said to be inspired by 100 year old process called acetone-butanol-ethanol fermentation, which was developed by chemist Chaim Weizmann (who also happens to be the first president of Israel). In recent years, researchers in the field of biofuels, Edinburgh Napier University Research Centre, tuning and fine-tuning the process of distillation of the products come with Glenkinchie Distillery Diageo. Diageo is a whiskey brand Johnnie Walker, J & B, Talisker Single Malt Glenkinchie and natural.

Each year, Scotland GBP4 billion (approximately U.S. $ 6,200,000,000) whiskey industry produces about 1.6 billion liters of beer sweat – liquid copper kettles – and 187,000 tons of wine lees – burnouts. This research led by Professor Martin Tangney has succeeded in these waste materials in Biobutanol.

Butanol is a four carbon alcohol, which is said to be up about 30 percent more energy than ethanol, and has a lower vapor pressure boiling point makes it easier and more manageable. It is also less corrosive for easier transportation and storage, and that ethanol can be blended with gasoline, butanol can be blended with diesel or biodiesel. It is significant that butanol can also be used as a standalone transportation fuel in conventional vehicles without a special engine modification. In addition to use as biofuel, is Biobutanol new product is also used for producing other renewable bio-chemicals such as acetone.

Professor Tangney said: “The European Union has said biofuels That should be 10 percent of total fuel sales in 2020 to form. While Some energy companies crops specifically for biofuels production, WE have a surplus of material for study, as it produces whiskey development. This is more environmentally sustainable solutions, and offers new potential revenue on the back of one of the largest industries in Scotland. ”

Napier University in Edinburgh now filed a patent for a new biofuels and plans to manage the new product in commercial production is – next stop, a petrol pump.

imaGinyze is a new app, which augmented reality to your car through iPhone. Once it is installed in the middle of the dashboard, an iPhone with imaGinyze installer, the job you are to detect, to mark the border region lines that match the painted lines on the road, and fill the inside with a blue overlay. When the app on your path has been, can detect all the vehicles in front of you within a certain range. imaGinyze also flashes a “Vehicle Ahead” signs when approaching a car from behind. Cars with front are color coded by proximity – the first green, yellow as you approach the next and then to red when you can come close.

For security reasons, this interval as appropriate, giving the driver enough warning for the speed or switch tracks and pass reduction. While changing lanes, roadway detection requires a purple overlay on track to open (this is the “lane departure mode”) and warns drivers of cars that are adjacent lane.

imaGinyze also provide other information, such as the pitch of the road and the cars drive like you do not trust your own speed.

The homepage of the application is ready to point out that your iPhone be mounted at a height of approximately 1 to 1.5 meters in landscape mode. Some reference materials may be necessary to ensure that the application functions correctly.

It should be noted that this app is one of the first of its kind, has probably not yet reliable enough to depend much on the road. It is just version 1.0 and user reviews about the iTunes application on that page shows imaGinyze still a lot of work. Although we did not try it yourself, we’re delighted to see such a promising development in the area for car AR technology and the possibilities it has for the future of driving.

Personally I would love to see what the Japanese AR gurus on Sekai Camera could do in this area.

Make sure you check out imaGinyze video demos below to get a better idea of how the program works to get while driving.

Laptops are appropriate name as they sit nicely on your lap. If you’ve ever tried to take advantage of one, but you’ll know it’s not the most ergonomic set-up can imagine – you bend your head down, keep your knees up, and feel of your thighs get toasty warm Computer-generated heat which apparently is unable to spread in the air. To power laptops in other ways, several companies offer laptop stand on your desktop, devices from your shot himself in an office-like computer workstation, gizmos, so your laptop back on the passenger seat of your car, or to let you use your bedside. If only one who saved your laptop for you while you lay on your back … There are, of course, and Hong Kong based company OMAX has a number of them to choose from.

There are different models of laptop tables, but they all basically down to the same: get an easel-like stand with a pair of scissors, folding legs on each side. While the more basic models have a simple hole in the air to the ventilation, chrome they have built in fans that run off your computer USB port and silica rubber presses your laptop to stop sliding.

There are a number of ways objects can be used. Almost completely folded down, they can serve as a simple desktop stand. Drew a little higher, you can find them on the carpet with your legs under them, put them on your legs or sitting in a chair. With their legs raised, you can use it while standing, or beside your bed. And yes, as I said, you can use them in bed, in a way that your computer is held over your face as you lie on your back.

The OMAX Laptop tables are made of aluminum and come in many different colors. They fold flat when not in use and can also be used for tablets, with or without a separate keyboard. Check their website for more information.

Ricoh Announces CX4 Compact Digital Super Zoom Ricoh has announced a sequel to the popular CX3 Compact Super Zoom, which sports a new body design, auto-focus tracking and improved image stabilization. Described by the company as “skilled and stylish, the 10-megapixel CX4 retains its predecessor high resolution LCD screen, wide angle optical zoom and 720p video function, but now improved noise reduction and a special night landscape mode. Of CX3, the new model inherits a back-lit 10-megapixel CMOS sensor, 10.7 x wide angle optical zoom lens with a focal length of 4.9 to 52.5 (28 – 300mm equivalent), a 3-inch, 920,000 pixel resolution LCD display and 720p video recording in Motion JPEG format. The eleven scene shooting modes make it to CX4 and the camera will continue to Ricoh’s Smooth Imaging Engine IV to use logic. And a transformed body, the new CX4 also object tracking autofocus which promises to focus the subject automatically to keep the right exposure when the shutter is pressed. Besides the camera, ISO100 to ISO3200 sensitivity, Ricoh has also completely revised version of the image sensor shift image stabilization and concludes that it can help CX4 reduce blur, which corresponds to 3.7 shutter stops for better pictures in low light or high zoom situations. For night owls, the new night panorama multi-shot mode may prove useful, combination of four different exposures to a single image to produce less noise. Although the topic of noise reduction, select the maximum setting allows variance estimates Noise Reduction, which the noise distribution of image data to analyze and optimize each area of the shot for clarity without increasing the resolution, tone or color. Users are also offered some creative shooting modes to get help from their inner artist – such as soft focus, toy camera, or dynamic range. The CX4 has pocket-friendly 3.99 x 2.30 x 1.15 inch (101.5 x 58.6 x 29.4mm) dimensions, even at its thinnest point, it is not as thin as 0.96 inch (24.4 mm). It is said that is about five frames per second continuous shooting at full resolution and the rechargeable battery good for around 330 images. -Storage missing SDXC power is therefore limited to a maximum of 32 GB with SD / SDHC card slot, and although there is a USB 2.0 port, no HDMI-out so have seen high-definition videos on a big screen TV, a bit more effort. The CX4 will be available from early September in black, champagne silver, pink and purple for U.S. $ 399

With the advent of 3D glasses with polarizing filters and LCD shutters could be misled into believing that we have seen in recent archetypal 3D glasses with different color filters. Well, to think again, because European researchers came up with the technology that can say that a 3D image on a screen in full resolution without attenuation of ambient light, an unlimited viewing angle and less pressure on the eyes than other 3D technologies – and then based on glasses with different colored filters.

It is no secret that 3D technology is not perfect. After the initial shock of the latest 3D lot of fun, best illustrated by the Avatar people started to notice some bugs. Glasses – both passive (polarized) and active accounts – provides a noticeable darkening of the image. Besides having a shell of the new 3D TV probably has noticed that to be seen with his head upright. Just tilt your head can change color and shadows, while adjusting the image disappears completely. As widely reported that some people suffer from headaches and nausea for some time 3D tracking. Not exactly what one would expect the next big thing in home entertainment.

Eureka Swiss and German researchers claim to have developed a technology that overcomes these problems. The advance is the result of three friends in a German company Infitec want to make a 3D LCD screen can display full-resolution formats of the new HDTV.
Everything old is new again

Infitec developed technology for 3D cinemas, called wavelength multiplexing, based on the old red and green glasses. Businesses are using a color much closer eye hand wave of the traditional red and green glasses to improve image quality, using specific wavelengths of red, green and blue for right eye and the different wavelengths of the same color on the left. Filtering a specific wavelength, which allows images to the left and right eye, a viewer the illusion of 3D.

Infitec then together with the Swiss Optics Balzers company specializing in 3D and two filters in companies supported the initial development of the LCD screen 3D. While Infitec considered the best sign and lighting for use in a display and software for the project, Optics Balzers developed a special filter for light and glass.
Show Dualplex

Finally, the partners decided it would be necessary for a completely new optical design of the display cabinets. Finally, four LEDs – green, one red and one blue – a number of necessary colors. The end result was a demonstration of a 23-inch screen, the computer asks Dualplex screen. They argue that image quality is less strain on your eyes that 3D technology, need glasses do not darken the ambient light and causes the screen is visible from all angles without distortion of images in 3D.

“Viewers will screen stretched on the bench you will see your head in all directions, and the picture will not change,” says Simon Arnold, Director of Technology Infitec.

Partners has applied for patents on display in Germany and in the process patents in other countries, the latest 3D LCD for private consumers. Initially, however, the partners thought it would be easier to focus on specialized fairs, such as doctors – through 3D imaging to help doctors perform surgery, for example.

Although it sounds promising, like the current crop of 3D technology is showing signs of Dualplex screen. Therefore, treat, and contain our enthusiasm until we see him in his Peepers.
