Car Automobile Technology From Time to Time

noreply@blogger.com (Kurt Donie Cobain) — Thu, 24 Jul 2008 03:12:00 +0000

Automobile or known as car have expansion of technology from time to time. There is time where car runned by steam engine, and then for the latest era we use gasoline to move cars. Maybe in the future it will back to water energy again considering of earth energy crisis but ofcourse in the modern thing not like old time where the machine is very big and not fashionable model and not simple. According to wikipedia about steam engine car that Steam-powered self-propelled vehicles were devised in the late 17th century. Then Richard Trevithick had developed the use of high-pressure steam, around 1800, that mobile steam engines became a practical proposition. The first half of the 19th century saw great progress in steam vehicle design, and by the 1850s it was viable to produce them on a commercial basis. The next sixty years saw continuing improvements in vehicle technology and manufacturing techniques and steam road vehicles were used for many applications. In the twentieth century, the rapid development of internal combustion engine technology, coupled with adverse legislation, led to the demise of the steam engine as a source of propulsion of vehicles on a commercial basis, with relatively few remaining in use after the Second World War. However, many vehicles were acquired by enthusiasts for preservation, and numerous examples are still in existence. Moreover, the threat of Global Warming, and the search for renewable energy sources, has led to a resurgence of interest in utilising steam as a power source for road vehicles in the future.

Geological changes could predict earthquakes

Discovery may lead to development of early-warning system

By Will Dunham

updated 6:02 p.m. ET July 9, 2008

WASHINGTON - Scientists working at California's San Andreas Fault have detected subtle geological changes occurring hours before an earthquake that could enable them to develop an early-warning system aimed at saving lives.

Their instruments detected geological changes most likely caused by tiny fractures forming in the rock ahead of an impending earthquake due to stress in the Earth's crust, according to seismologist Paul Silver of the Carnegie Institution in Washington, one of the researchers.

"It's the opening up of cracks before an earthquake," Silver said in a telephone interview.

The research, published on Wednesday in the journal Nature, was conducted using wells dug 0.6 miles deep into the quake-prone fault at Parkfield, Calif.

Their equipment generated and recorded seismic waves before, during and after two small quakes, allowing them to observe these small, predictive geological changes.

In the first case, the geological signals occurred 10 hours before a magnitude 3 quake in December 2005. The same sort of signals also occurred two hours before a magnitude 1 quake that happened five days later, the researchers said.

"We are very encouraged by these observations, and we are planning for more experiments to confirm whether these changes are part of the general physical processes before an earthquake," seismologist Fenglin Niu of Rice University in Houston said in a telephone interview.

Scientists have made strides in understanding earthquakes, but finding changes in the Earth's crust that could allow for an advance prediction has remained difficult.

Current earthquake warning systems provide at best a few seconds notice before an earthquake strikes.

The findings were published just two months after a powerful earthquake in China. The May 12 quake in Sichuan province killed about 80,000 people, with many killed when buildings such as schools collapsed.

"To get the point where we have a practical early warning system for earthquakes, that's still a ways off — 10 years, maybe 20," Silver said.

If more research finds this effect to be pervasive before earthquakes, these findings may make that goal attainable, the researchers said.

"No matter how much time you have, there's something you can do. Even with a few seconds, you can automatically turn off gas valves. You may even be able to get a hard hat on your head or run outside of a building," Silver said.

"But with something on the order of 10 hours, you could perhaps evacuate populations, you could certainly get people out of city centers and areas that are deemed dangerous."

iPhone games we can't wait to play

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 22:52:00 +0000

From 'Spore' to 'Super Monkey Ball,' these games have us fired up

On your marks, gadget fans: The 3G version of the iPhone hits shelves on July 11 – but you already knew that, right? Well, then you also already know that the iPhone isn’t merely a phone, it’s also a music player and – best of all – a handheld video game system. It’s the games that have us most excited to try out Apple’s latest gadget.

These are the Top 5 iPhone games we’re itching to play. Check out the list then tell us which games you're looking forward to.

'Enigmo'

The 3-D puzzle game “Enigmo” features water, oil and lava pouring out of “droppers,” and it’s up to the player to guide these streams into a target by moving slides, bumpers and other objects. Speed is of the essence here as the faster you are, the higher you’ll score.

“Enigmo” costs $9.99 and was made available July 10.

'Spore'

One of our most anticipated games for the iPhone happens to be one of the most anticipated games of the year, regardless of platform. “Spore” has players creating life forms and then controlling their development from the bacterial stage on up to complex life form. Eventually, gamers will be able to launch their creations into space, where they’ll discover and conquer other worlds.

“Spore” is scheduled to be released in September.

'Super Monkey Ball'

“Super Monkey Ball” is a maze game with a twist: instead of controlling the character, you control its environment. You guide the monkey towards his goal by tilting the world around him. Be careful though, the more you tilt, the faster he rolls, and one wrong move can cause that monkey to fall right over the edge.

The game makes use of the iPhone’s motion-sensing accelerometer, as players control the action by physically moving the phone, just like you do with Nintendo’s Wii remote.

“Super Monkey Ball” costs $9.99 and was made available July 10.

'Crash Bandicoot Nitro Kart 3D'

“Crash Bandicoot Nitro Kart 3D” is a racing game more focused on fun than it is on physics. You’ll slip and slide around 12 different tracks, ranging from a desert land to Outer Space, each full of weapons and power-ups that you can use to get ahead of your competition. Win and you’ll be crowned “King of Kart Racing for all Eternity,” but lose and you’ll be banished from the land.

The release date for the iPhone version of “Crash Bandicoot Nitro Kart 3D” is as yet unannounced.

'Brain Challenge'

“Brain Challenge” is already available on mobile phones and other handheld devices, so we’re glad to see on the iPhone too. Cost is $9.99 at Apple's App Store, available through the iTunes Store.

Gameloft’s “Brain Challenge” aims to sharpen your mental skills through the use of fast paced mini-games, much like Nintendo’s popular “Brain Age” series. For instance, you’ll need to quickly pick the heavier of two items on a scale, or figure out the mirror-image of an object. These tasks start off easy, but you’ll soon be racking your mind trying to figure them out.

NASA plans industry day on IT infrastructure strategy

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 22:47:00 +0000

By William Welsh

NASA plans to hold an industry day July 23 in Washington to brief the private sector on the acquisition strategy for its Information Technology Infrastructure Improvement program (I3P).

The I3P solicitation will support several agency components and encompass network communications, data center, desktop and Web services, according to an announcement on the Federal Business Opportunities Web site.

In addition to communicating its acquisition strategy, NASA will describe its IT infrastructure requirements across the components, get input from industry on its IT strategy and establish a list of companies interested in the procurement.

Registration, which closes July 21, is limited to two representatives per company, NASA said.

The event will be held at the Ronald Reagan Building and International Trade Center.

Transportation technology: Smart solutions or gimmickry?

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 22:28:00 +0000

Not surprisingly, the demand for transportation solutions has been getting a big boost from post-Sept. 11 efforts to make highway travel more secure, especially across borders and through other checkpoints.

The top players in this market expect government officials to make intelligent transportation systems a major component of homeland security — a logical extension for systems that can track vehicles, control traffic flow and monitor shipments of hazardous materials.

In our cover story this issue, Staff Writer William Welsh details some of the efforts to expand the security-related role of transportation systems, as well as some of the obstacles to integrating these systems with the police and other public safety organizations.

But a word of caution before you get carried away by the claims in our cover story. First read our “Survival Guide” interview with Washington Post columnist Ron Shaffer, a.k.a. Dr. Gridlock, the self-described “Ann Landers of commuters” for the Washington region. Dr. Gridlock said he is skeptical that information technology can do much to help commuters, calling transportation systems he has seen “more gimmickry than solution.”

Those of you who build intelligent transportation systems may want to invite him out to see your solutions in action.

Hybrid Vehicle Technology

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 21:57:00 +0000

from : http://www.transportation.anl.gov/hev/index.html

Argonne researchers are developing and testing various hybrid electric vehicles (HEVs) and their components to identify the technologies, configurations, and engine control strategies that provide the best combination of high fuel economy and low emissions.

Because of the number of possible advanced powertrain configurations, developing HEVs and fuel cell vehicles requires accurate, flexible simulation tools. As a result, Argonne has developed the Powertrain System Analysis Toolkit © (PSAT) under the direction of Ford, General Motors, and DaimlerChrysler. This forward-looking model simulates vehicle fuel economy, emissions, and performance in a realistic manner — taking into account transient behavior and control system characteristics. PSAT can simulate an unrivaled number of predefined configurations (conventional, electric, fuel cell, series hybrid, parallel hybrid, and power split hybrid).

Argonne also serves as the lead laboratory for hardware-in-the-loop (HIL) and technology validation for the U.S. Department of Energy (DOE). HIL is a technique for performing system-level tests in a quick and cost-effective manner. Argonne employs HIL techniques to evaluate new technologies and control strategies in an emulated vehicle environment. With HIL, actual components can be evaluated under realistic operating conditions.

Furthermore, Argonne developed the software — PSAT-PRO© — that automatically commands and controls vehicle subsystems to effect the emulation. The PSAT-PRO© software is integrally linked to the PSAT© software, but it is still generic enough to go from modeling to prototyping for any kind of hybrid configuration. It was designed to control any kind of hybrid powertrain system or subsystem.

Fuels

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 21:53:00 +0000

from : http://www.transportation.anl.gov/fuels/index.html

There is a renewed interest in alternative and renewable fuels for the transportation sector due to U.S. dependence on foreign oil, rising crude oil costs and transportation emissions. Fuels produced from feedstocks within the U.S. border provide energy security and stability in pricing.

To promote and stimulate alternative and renewable fuel research, the U.S. Renewable Fuel Standard has made it a requirement to increase the production of ethanol and advanced biofuels to 36 billion gallons by 2022. Public concern over mobile sources of air pollution provides an additional incentive to produce fuels that generate fewer emissions and increase efficiency.

The primary focus of Argonne's alternative and renewable fuels research program is the acquisition and dissemination of emissions, efficiency, and performance data from both engines and vehicles operating on various fuels. This is accomplished by utilizing the extensive engine and vehicle testing facilities combined with the latest data acquisition equipment for in-cylinder combustion, as well as exhaust system analysis. In addition, development of mechanistic models with an emphasis on practical applications is currently being pursued through utilization of world-class chemistry kinetics, dynamics, and quantum chemistry. By employing Argonne’s vertically-integrated team to bridge basic combustion research and applied engine systems, improved understanding and operation of various alternative and renewable fuels is attainable.

If you didn't know it was there, you'd have no idea that deep in the Tennessee woods, about a 20-minute drive from Knoxville, is one of the world's great supercomputer labs. It's no accident, of course. The facility is part of the Oak Ridge National Laboratory, one of the world's leading research institutions and the site of the reactor in which plutonium for the first atomic bombs was refined during World War II.

As one of the last stops on Road Trip 2008, CNET News.com reporter Daniel Terdiman stopped in at Oak Ridge last week to get a firsthand look at the existing supercomputers--and to hear about a new one coming online soon that will be among the world's most powerful. He also got to see that original reactor and visit with one of the scientists leading the research center's work into more efficient biomass for ethanol.

This is one row of the lab's Cray X1E, the largest vector supercomputer in the world and the 175th most powerful computer overall. It is rated for 18 teraflops of processing power. It is arrayed in multiple rows, with aisles for walking through. The computer is liquid-cooled, and piping was installed into the floor for that purpose.

Robot maker’s fortune built on a simple idea

noreply@blogger.com (Kurt Donie Cobain) — Fri, 11 Jul 2008 21:36:00 +0000

iRobot thrives by conquering a common household chore: cleaning the rugs

By Lauren Kesner

CNBC

updated 7:28 a.m. ET July 9, 2008

CAMBRIDGE, Mass. - In the popular 60s sci-fi cartoon series, "The Jetsons," the family maid, Rosie the Robot, was the stuff of futuristic fantasy.

Not anymore. If you think robots are the stuff of science fiction, try telling that to the man who’s made a fortune building them.

Colin Angle is CEO of iRobot, the company that came up with a round, rolling creation called the Roomba. Barely three inches high and 13 inches across, this robot knows how to clean.

And, according to Angle, a Roomba has a lot on its mind when it does its job.

“Am I doing the same thing over and over again?” he said, describing the way the Roomba thinks. “Because I'm in some kind of small area box and I need to figure out how to escape? Or have I just ingested a wire or tassels on a rug, and I need to put that back down and continue? Or am I nearing the end of my battery life, and should I go back and look for my docking station? So it's constantly asking itself these questions.”

It takes brains to invent something with a mind of its own. Angle says it all started in 1991 when his thesis as an undergraduate at MIT — a six-legged walking robot named Genghis — launched him on a life-long journey to make cool robots.

“After completing it, it was, ‘Okay, what's next?’” he said. “What is the coolest next robot I might do?"

Angle set up shop in his living room with a college friend, their robotics professor, and a pile of credit card debt.

“The challenge was always making ends meet,” he said. “And it really turned into a 24-hour-a-day sort of thing. I was eating, sleeping, or building robots.”

Whenever Angle told people about his robot start-up company he always got the same response.

“’Oh, so when are you going to clean my floors?’" he said. “Because they'd all heard about Rosie the Robot from 'The Jetsons.' That's what they wanted. And I'd say, "Well, how much are you willing to pay? $5,000?’ They'd say, ‘No, no, no. Have a good day.’ So that we knew that there was a price. And that's why it took so long.”

After 12 years of tinkering, Angle and his team came up with the Roomba.

At a price of just $200, it was the first affordable consumer robot. A few days after the 2002 launch, Angle got a call from a buyer.

“And she said, ‘I have a question for you: How many more Roombas do you think you can build between now and the end of the year?’" said Angel. “And I told her the number. And she said, ‘Okay, we want all of them.’ And that was this 'Yes!' kind of moment when we knew we had something special.”

IRobot is onto something big. Their 2005 initial public offering of stock turned Angle and his two co-founders into multimillionaires — and that was just the beginning.

To date the company has sold over 3 million Roombas – but they’re not just cleaning house. They’ve also sold over 1,400 bomb disposal robots called Pakbots. It may look like fun and games, but for Angle, there’s still plenty of work ahead.

“When I think about how much we've accomplished, and I think about have we achieved the goals of creating an industry of practical robots, I could say, well, we've made a start,” he said. “But there's so much more to do, that I don't feel like I'm done. I don't feel like I'm close.

Though the company's stock has had its ups and downs, Angle says the future is bright. Some analysts are predicting that the market for home robots will grow to a $15 billion business by 2015.

Product Review of LG Dare (Verizon Wireless)

Reviewed by: Nicole Lee
Reviewed on: 06/27/2008
Released on: 06/26/2008

One of the most notable fallouts of the Apple iPhone launch last year is the ever-growing trend of touch-screen phones. LG was one of the first manufacturers out of the gate with phones such as the LG Voyager and the LG Vu dazzling us with features that we couldn't get on the iPhone, like live mobile TV and 3G connectivity. Samsung then came blazing out with the Instinct, a phone that directly targets the iPhone with visual voice mail, integrated GPS, and corporate e-mail support. Yet, many of these phones still walked on familiar ground with its design and features.

LG's latest handset, however, dares to take things in a different direction. The appropriately named LG Dare presents a few tricks we haven't seen before in the touch-screen phone genre. For example, you can drag and drop icons to make your own customized shortcuts on the home screen, or you can use a drawing pad to sketch ideas or draw a map, which can then be sent via MMS to a friend. The Dare also has one of the most advanced cameras we've seen on a touch-screen phone--its 3.2-megapixel camera has settings like face detection, noise reduction, panorama photo stitching, and a SmartPic technology designed for taking photos in low light. The built-in camcorder can even record high-speed video and play it back in slow-motion, which is a first for U.S. camera phones. We certainly wouldn't want to call this an iPhone killer since it doesn't have features such as Wi-Fi, and its Web browser and media player aren't as good. However, the Dare is a very appealing alternative for Verizon customers who want a touch-screen phone with a difference. The LG Dare is priced competitively at $199 after a $50 mail-in rebate and a two-year service agreement.

Design
Like all touch-screen phones, the LG Dare's design is dominated by a large display covering almost the entirety of the phone's front surface. Indeed, the only visible keys on the front are the Call, Clear/Voice command, and End/Power keys at the very bottom. The Dare is quite a bit smaller than both the iPhone and the Samsung Instinct, measuring only 4.1 inches long by 2.2 inches wide by 0.5 inch thick. It has a stainless steel border along its sides, and a black soft touch surface on the back that gives it a nice grip in the hand. It weighs about 3.76 ounces, which gives it a light yet solid feel.

The smaller size of the Dare also results in a smaller space for the 3-inch-wide display (compared with the 4-plus-inch displays on the other two phones). Though we were fine with it for most applications, we'll admit that it deters us from enjoying the full HTML browser (which we'll get to in the Features section), since it means we have to do more scrolling than usual. The display supports 262,000 colors and a 240x400-pixel resolution, which results in a stunning and colorful screen with vibrant graphics and clean text. You can adjust the backlight time, the menu fonts, the dial fonts, the display theme, and even the image of the charging screen. You can also choose animated wallpaper if you like.

The LG Dare has an innovative drag-and-drop menu interface.

Along the bottom row of the display's home screen are five shortcut icons to the messaging in-box, the phone interface, the main menu, the phonebook, and a favorites menu (which is a customizable graphical layout of up to nine favorite contacts). There's also a small arrow icon on the far right of the display (about a third of the way down), which leads to a list of 11 shortcuts that you can select from 51 possible applications. You can drag and drop these shortcut icons to change the order in which they appear. However, the coolest thing is that you can also drag and drop them directly to the home screen. Simply tap on an icon and drag it toward the home screen, and let go. You can then arrange the icons anywhere on your home screen as well.

Going back to the Favorites menu, not only do you have a graphical layout of your favorite contacts, but you can also drag and drop them around the screen. After selecting a contact, you can either have instant access to a new text message or an immediate phone call. You can also edit that contact information on the spot.

Another innovative aspect of the Dare's touch screen is the option for a "scattered" menu interface layout. You can then drag and drop the scattered icons to new positions in the menu. We found this to be quite fun and intuitive, but can't help but think it's rather unnecessary. We would have been just as happy with the traditional grid menu layout (which is a menu style option as well). Throughout the menu interface, you will see a back arrow on the upper left, which will lead you back to the previous screen, and a Home button, which will lead you back to the home screen.

Like the Instinct, the Dare offers haptic tactile feedback, which gives tiny vibrations when tapping on the screen. It's very helpful when selecting menu options, since it provides a physical confirmation of the selection. You can go through a calibration wizard to adjust to the screen's sensitivity, and you can adjust the vibrate type (short, double, or long) and vibrate level (low, medium, high, or off altogether). You can also turn on "vibration when scrolling," which sets off tiny vibrations when scrolling up and down lists. We actually recommend this, so you know you're scrolling through a list and not accidentally selecting something.

The LG Dare has a virtual QWERTY keyboard.

This brings us to the touch interface itself. While we largely enjoyed the touch interface experience, we have to admit there is still a slight learning curve. Often we would select something without meaning to, especially when scrolling up and down lists or dragging icons around. The touch interface is certainly more sensitive than we thought it would be, even after going through the calibration wizard. After a day or two of fiddling around with it though, we learned to adjust.

We found dialing and texting to be quite easy, even with the touch-screen interface. The phone interface consists of the standard numeric keypad, a voice command button, a handwriting button that will let you "write" the numbers instead of using the keypad, plus two shortcuts to the recent calls list and the contacts list. The keypad features nice big numbers, and after you're done dialing, you can hit either the green Call button, or the physical Talk button on the lower left. There's also a Save key for storing new phone numbers. During a call, a few shortcut icons appear to activate the speakerphone, call mute, send a text message, add a note, connect to a Bluetooth headset, and even voice record.

There are several input options for texting. You can either use the virtual T9 keypad, or you can twist the phone 90 degrees in the counterclockwise direction and a QWERTY keyboard will automatically appear. We're then able to tap on each key with our thumbs. Tapping each key will magnify that key momentarily, just like on the iPhone. The keyboard has a dedicated space bar, return button, period, and alias (@) keys, plus a Shift button to switch between capital letters and other symbols. Unlike the iPhone, you can indeed copy and paste text, simply by highlighting with your fingers and hitting a Copy button. However, the Dare doesn't correct your spelling.

The LG Dare has a 3.5mm headset jack.

Another method for entering text would be via handwriting, or a graffiti method. The handwriting recognition works quite well, but we did have some problems with it. For one thing, we had to keep switching modes between capital letters, lowercase letters, numbers, and symbols--it wasn't smart enough to figure out the characters on its own. Also, it's a lot easier to handwrite with a stylus, or if you have long fingernails--using just our fingertips resulted in more mistakes.

The Dare also has a proximity sensor that will automatically turn off the LCD while in a call to prevent accidental touch input, similar to the iPhone. It also has a light sensor that adjusts brightness automatically to conserve on battery life. As mentioned above, the Dare has an accelerometer that will rotate the display 90 degrees counterclockwise for certain applications like the browser, the texting keypad, and other applications. For the picture view screen and the music player, the screen can be rotated 360 degrees.

On the left spine of the Dare is a Hold key, a microSD card slot, a speakerphone key, and a USB charging jack. On the top is a 3.5mm headphone jack, while the volume rocker and dedicated camera sit on the right spine. On the back of the phone is the camera lens and LED flash. There's no self-portrait mirror though.

Features
The Dare comes with a generous 1,000-entry contacts list with room in each entry for five numbers and two e-mail addresses. You can also save callers to groups, and you can pair them with a photo and one of 26 polyphonic ringtones. Other essential features include text and multimedia messaging, a vibrate mode, a speakerphone, a calculator, a tip calculator, a calendar, an alarm clock, a stopwatch, a world clock, and a notepad. More advanced features include full Bluetooth support with stereo A2DP, the capability to use the phone as a modem, and file transfer. There's also mobile e-mail, mobile instant messaging, a USB mass storage mode, voice command and voice dialing, voice recording, and GPS functionality via Verizon's VZ Navigator service. Mobile e-mail is restricted to popular Web mail services such as Hotmail, Yahoo, and AOL, so it's not nearly as robust as using a smartphone.

A nice bonus feature on the Dare is a drawing pad. This pad lets you sketch little doodles or draw a rough map with a variety of pen sizes and colors. You can then send this image to your friends via MMS if you wish.

The Dare has a full HTML browser. It won't support Flash, but that's fine for a phone such as this. As we mentioned earlier, you can rotate the phone to display the browser in landscape mode, which makes entering URLs a lot easier via the QWERTY keyboard. However, the browser experience is nowhere as clean as the Safari browser on the iPhone. Zooming in and out is a pain--we had to use either the onscreen controls or the volume keys to do so. Panning the browser page with our fingers took some time, as the screen responded slowly. Also, since the display is small, we often had to do a lot of scrolling to see everything. Alternatively, if we zoomed out to see the browser page in full-screen mode, the text would be too small to read (The camera key can be used to see the full screen overview as well). You can bookmark pages as well as send URLs to your friends via e-mail, which is a nice touch. However, the overall experience left us cold, and we almost would rather opt for the stripped-down mobile versions of the Web sites instead.

Of course, since the Dare is on the Verizon EV-DO network, it also has access to Verizon's broadband services in the form of V Cast Video and V CastMusic. The V Cast Video and V Cast Music experience is the same as that on other phones. However, the music player interface is quite improved over what we've seen before. There are shortcut icons to Play All, Shop, and Sync, which correspond to the full playlist, the V Cast Music store, and USB syncing respectively. Songs are automatically categorized by genre, artist, and album, and settings include repeat and shuffle. When playing a song, you get the typical play, pause, and track shuttle controls, plus you get to see album art as well. There's even a pseudo Cover Flow that lets you flick through songs by moving your finger across the screen. The Dare also has something called Background Mode Music that lets you listen to music in the background while doing other things--the music pauses when you receive calls, and when the call ends, the music will resume where you left off. The Dare has a microSD card slot that supports up to 8GB of additional storage.

The LG Dare has a 3.2-megapixel camera on the back, plus an LED flash.

Arguably, the best feature of the Dare, however, lies in its 3.2-megapixel camera. You can take pictures in five resolutions (2,048x1,536, 1,600x1,200, 1,280x960, 640x480, and 320x240), five white balance presets, five color effects, four ISO settings (Auto ISO, ISO 100, ISO 200, and ISO 400), and six preset scenes. Other camera settings include spot or average photometry, multishot, three shutter sounds (with a silent option), auto focus, a self-timer, flash, and four different shot types (Normal, Panorama, Split, and Frame). It even offers face detection to ensure someone's face is in focus and noise reduction, which reduces the amount of artifacts in an image. Most notably, however, is something called SmartPic technology, which enhances images with face color compensation (dubbed Smart Beauty), as well as light compensation (dubbed Smart Light)--especially in low light situations.

The LG Dare has excellent photo quality.

The Dare has an excellent Schneider-Kreuznach certified lens that promises excellent photo quality, and it delivers. Images looked sharp, with accurate colors, and everything looked in focus. After you take your picture, you are presented with an array of image-editing options, such as zooming, rotating, cropping, changing the contrast, sharpening, and blurring. You can even use your finger to doodle over the image, or edit it with frames, effects, and stamps.

The built-in camcorder isn't too shabby either. It's one of the first camera phones to record up to three resolutions (176x144, 320x240, and 640x240 VGA)--the VGA format is only for storing on the device, since MMS can't support files that large yet. You can record videos up to 470KB for MMS. Settings are similar to that of the still camera. Another bonus option is the ability for high-speed video recording. You can record videos in 120 frames per second (fps) and then play it back with 15fps slow motion. This is the first phone in the U.S. that has this functionality. Video quality was surprisingly decent. The action movements looked blurry with some jerkiness, but it's not that bad for a camera phone. You can trim videos plus add fade effects as well.

You can personalize the Dare with lots of wallpaper, graphics, sounds, alert tones, and more. The Dare doesn't come with any games, but you can download them, as well as more graphics and sounds, via the Web browser.

Performance
We tested the LG Dare in San Francisco using Verizon Wireless service. Call quality was absolutely excellent. Voices sounded loud and clear, with almost no static and echo. Callers said we still sounded like we were on a cell phone, but other than that, there was no distortion. Even when we used the speakerphone, callers said there was little to no difference in sound quality. On our end, callers sounded great as well. Speakerphone quality was a tad on the tinny and hollow side, but we could still hear them just fine. We also paired the Dare with the Plantronics Discovery 925 Bluetooth headset without a problem.

We were very impressed with the EV-DO Rev. A speeds. Web pages loaded in mere seconds, and it took about a minute to download a 1.5MB song. V Cast videos loaded without a lot of rebuffering, though streaming video quality still looked pretty pixelated. Sound quality was very good as well; the speaker has decent sound output, but we would rather use a stereo headset instead.

The LG Dare has a rated battery life of 4.6 hours of talk time and 15 days of standby time. According to FCC radiation tests, the LG Dare has a digital SAR rating of 1.09 watts per kilogram.

Biogas

noreply@blogger.com (Kurt Donie Cobain) — Mon, 12 Nov 2007 14:54:00 +0000

Biogas typically refers to a (biofuel) gas produced by the anaerobic digestion or fermentation of organic matter including manure, sewage sludge, municipal solid waste, biodegradable waste or any other biodegradable feedstock, under anaerobic conditions. Biogas is comprised primarily of methane and carbon dioxide.
Depending on where it is produced, biogas is also called:

swamp gas
marsh gas
landfill gas
digester gas
Biogas containing methane is a valuable by-product of anaerobic digestion which can be utilised in the production of renewable energy [1].Biogas can be used as a vehicle fuel or for generating electricity. It can also be burned directly for cooking, heating, lighting, process heat and absorption refrigeration.

That`s definition from http://en.wikipedia.org/, and i thing the energy resources have play role for people needs. Its play all activity to move the machine hat make people job getting easier. For nowadays that be a big problem because, its getting less and less. So people got to find another alternative energy that could produce quick, easy, cheap and not make any polution. Maybe biogas is one of energy alternative that will make people never worried again about energy. Because it makes from things that unused around us. It makes our world keep clean, but it still keep learning again because that is not so simple. So we just hope the scientist still doing their science to make us free from energy resources phobi.

Biogas and anaerobic digestion

Biogas production by anaerobic digestion is popular for treating biodegradable waste because valuable fuel can be produced, while destroying disease-causing pathogens and reducing the volume of disposed waste products. It burns more cleanly than coal, and emits less carbon dioxide per unit of energy. The harvesting of biogas is an important part of waste management because methane is a greenhouse gas with a greater global warming potential than carbon dioxide. The carbon in biogas was generally recently extracted from the atmosphere by photosynthetic plants, so releasing it back into the atmosphere adds less total atmospheric carbon than burning fossil fuels.

Recently, developed countries have been making increasing use of biogas generated from both wastewater and landfill sites or produced by mechanical biological treatment systems for municipal waste. High energy prices and increases in subsidies for electricity from renewable sources (such as renewables obligation certificates) and drivers such as the EU Landfill Directive have led to much greater use of biogas sources.

Landfill gas

Landfill gas is produced from organic waste disposed of in landfill. The waste is covered and compressed mechanically and by the pressure of higher levels. As conditions become anaerobic the organic waste is broken down and landfill gas is produced. This gas builds up and is slowly released into the atmosphere. This is hazardous for three key reasons:

Risk of explosion
Global warming through methane as a greenhouse gas
Volatile organic compounds (VOCs) as precursor to photochemical smog

Biogas composition

The composition of biogas varies depending upon the origin of the anaerobic digestion process. Landfill gas typically has methane concentrations around 50%. Advanced waste treatment technologies can produce biogas with 55-75%CH4 [3].

Typical composition of biogas[4] Matter %
Methane, CH4 50-75
Carbon dioxide, CO2 25-50
Nitrogen, N2 0-10*
Hydrogen, H2 0-1
Hydrogen sulphide, H2S 0-3
Oxygen, O2 0-2*

Siloxanes and gas engines

In some cases, biogas from landfills and sewage treatment contains siloxanes. During combustion of biogas containing siloxanes, silicon is released and can combine with free oxygen or various other elements in the combustion gas. Deposits are formed containing mostly silica (SiO2) or silicates (SixOy) in general, but can also contain calcium, sulphur, zinc, phosphor… as indicated by the analysis piston scrapings from biogas-fired engines. These (mostly white) deposits can ultimately build to a surface thickness of several millimetres and are difficult to remove by chemical or mechanical means.

In internal combustion engines deposits on pistons and cylinder heads are extremely abrasive and even a small amount is sufficient to cause enough damage to the engine to require a complete overhaul at 5,000 h or less of operation. The damage is similar to that caused by carbon build up during light load running of diesel engines. Deposits on the turbine of the turbocharger will eventually reduce the charger’s efficiency.

Luckily, simply cooling the gas to roughly -4 C is sufficient to remove siloxanes due to condensantion.

Stirling engines are more resistant against siloxanes, though deposits on the tubes of the heat exchanger will reduce the efficiency

Safety

The methane in biogas forms explosive mixtures in air. The lower explosive limit is 5% methane and the upper explosive limit is 15% methane.

Biogas to natural gas

If biogas is cleaned up sufficiently, biogas has the same characteristics as natural gas. In this instance the producer of the biogas can utilize the local gas distribution networks. The gas must be very clean to reach pipeline quality. Water (H2O), hydrogen sulfide (H2S) and particulates are removed if present at high levels or if the gas is to be completely cleaned. Carbon dioxide is less frequently removed, but it must also be separated to achieve pipeline quality gas. If the gas is to be used without extensively cleaning, it is sometimes cofired with natural gas to improve combustion. Biogas cleaned up to pipeline quality is called renewable natural gas or biomethane.

Applications of renewable natural gas

In this form the gas can be now used in any application that natural gas is used for. Such applications include distribution via the natural gas grid, electricity production, space heating, water heating and process heating. If compressed, it can replace compressed natural gas for use in vehicles, where it can fuel an internal combustion engine or fuel cells.

Cooking

Gober gas is a biogas generated out of cow dung. In India, gober gas is generated at the countless number of micro plants (an estimated more than 2 million) attached to households. The gober gas plant is basically an airtight circular pit made of concrete with a pipe connection. The manure is directed to the pit (usually directed from the cattle shed). The pit is then filled with a required quantity of water (usually waste water). The gas pipe is connected to the kitchen fire place through control valves. The flammable methane gas generated out of this is practically odorless and smokeless. The residue left after the extraction of the gas is used as biofertiliser. Owing to its simplicity in implementation and use of cheap raw materials in the villages, it is often quoted as one of the most environmentally sound energy source for the rural needs.

Railway transport

A biogas-powered train has been in service in Sweden since 2005

Landfill gas legislation
United States
In the United States, because landfill gas contains these VOCs, the United States Clean Air Act and Title 40 of the Code of Federal Regulations (CFR) requires landfill owners to estimate the quantity of non-methane organic compounds (NMOCs) emitted. If the estimated NMOC emissions exceeds 50 tonnes per year the landfill owner is required to collect the landfill gas and treat it to remove the entrained NMOCs. Treatment of the landfill gas is usually by combustion. Because of the remoteness of landfill sites it is sometimes not economically feasible to produce electricity from the gas.

There a little definition of Biogas hope its usefull for all of you, that article i`ve found from http://en.wikipedia.org. Hope our lifes getting better and better.

20 million copies of Microsoft WIndows Vista Sale

noreply@blogger.com (Kurt Donie Cobain) — Thu, 08 Nov 2007 11:21:00 +0000

Microsoft corp, soled their newest operating system that is WIndows Vista on February but they claimed that number is still less than they expected. They thing they can sold more than that number, one month after launching. Michael Silver the vice president of Gartner research technology, Associated Press released.

Microsoft said their proud with Windows Vista sale, because it soled twice more than their product before. They said WIndows XP version sold 17 million copies after it aunched on 2 months period in 2001.
" This is good start and we glad with the sale number on the beginning , that shows WIndows Vista will be fastest Operating system adopted." says Kevin Kutz as a Windows Client Director. But remember that personal computer market grown twice than before since Windows XP launched, Silver says that Windows Vista sale should be more that that number. He said that 51 million computer sold for global market consumer on 2002, this year Gartner thing 96 million consumen will buy personal computer.
Microsotf didnt said how many user vista asking for upgrade on that time.But Dell Bob Kaufman said, about more than a half consumen buy computer on vacation and said they interest to used windows vista. Microsoft didnot say how many sale of Microsoft Windows Vista on retail, with reason 80% windows sale is from company of computer producen.

Polaris XDA Communicator

noreply@blogger.com (Kurt Donie Cobain) — Sun, 04 Nov 2007 05:26:00 +0000

O2 site has launched new picture of a newest XDA communicator. When we observed more deeper, this device very looklike with Xda orbit ( HTC Artemis communicator ) and could be O2 version from HTC Polaris GPS-communicator.

This device running on Windows Mobile 6 Professionale with GSM and UMTS network, bluetooth support and wi-fi also completed with 3 megapixel camera. This device has possibility using TouchFLO interface (finger input). But this news still not sure because O2 self not claimed that version from HTC Polaris device. Whatever their reason , the picture really exist, so not wrong if market guessthere will be Xda with HTC polaris base.

Strike Networks Will Introduce To You To IP Telephony

noreply@blogger.com (Kurt Donie Cobain) — Wed, 31 Oct 2007 21:33:00 +0000

Let's start by describing the new type of phone system that businesses are now using to replace traditional phone systems in their offices. An "IP Phone System" (sometimes called an IP PBX) uses the technology of "IP (Internet Protocol)" to carry the voice conversations in your office. This does not necessarily mean it uses the public Internet. An IP Phone System uses IP technology within the private data network of a business in a single location or across a private network. The same cabling that a business uses for its data network is used to carry the voice traffic of the phone system. In some ways they are totally independent and just sharing the same cabling. In one way they affect each other.

They are independent in that if the data server goes down, the voice will still go through. Your phone system will still work. Likewise if they phone system goes down, the data will still go through.

The way the IP Phone System and data network could affect each other is in the capacity or "bandwidth" of the network, both in the office and going to the outside world. Data is "forgiving" meaning it is not time sensitive. If it is delayed by several tenths of a second or seconds to move your data back and forth the quality of the data doesn't suffer.

However, voice is time sensitive. It must occur in "real time" which typically means there can't be more than 150 milliseconds (0.15 seconds) of delay in moving the voice traffic between its destinations. If the combined voice and data traffic is more than the capacity of the network infrastructure to handle it then the voice quality can suffer. The network infrastructure consists of the cabling and the equipment throughout the network.

IP Telephony on a properly designed, private network has the same voice quality as traditional phone systems. To be "properly designed" the network must include a proper "Quality of Service" plan and execution with the proper equipment. (That discussion is too much to include in this article. Give us a call.)

You can use IP Telephony over your private data network to connect remote sites with multiple workers or remote workers in home offices. If you don't have a private network between sites you can use the public Internet to access remote sites.

VOIP (Voice Over Internet Protocol) - How Does This Enter the Picture?

Although "VOIP" is often used to refer to IP Telephony as described below, it also refers to using the public Internet to carry voice traffic. When the public Internet is used, you (the user) don't have the same control over the Quality of Service as you do over your own network.

Therefore it is more likely that the voice quality over the Internet could suffer compared to that your private network. However, if properly designed with today's technologies, the voice quality over the public internet can often be equally as good as your regular phone line quality. The details of how this is accomplished, especially troubleshooting problems that arise, are too detailed to include here so that's left for another article or discussion with us.

IP Telephony - Why Would You Want It?

Your IP Telephone System provides the following advantages:

• Seamless extension dialing between all your locations on your private network, or even over the public Internet, is relatively easy and much less costly than traditional means. All your offices can be "tied together" to act as one large office no matter where in the world they are located. This also provides the advantage of eliminating long distance charges between your locations.

• IP Telephony creates lower cost and greater functionality advantages from carrier services. With IP Telephony you can connect all your offices together on your own private network. Or you can use the "quasi-private" network of a carrier.

This means you use one service provider to provide the voice trunks at each office. Your voice traffic between offices stays on the private network of the carrier. Your voice traffic never has to travel through the public internet.

If done correctly you have the advantage of carrying your voice traffic over the same network that carries your data traffic between offices but through the service provider you have Quality of Service to give voice priority over data. This will also give you a lower cost than the traditional means of a totally private network connecting your offices.

• Easily and economically connecting home based workers. Your home based worker can be easily connected to your office phone system with a high speed connection such as DSL or cable Internet. Your worker takes a phone from your office and connects it to that Internet connection. Or your worker uses a "soft phone" which is software on their computer at home that functions like a telephone.

That physical phone or soft phone, located anywhere in the world, is now a phone on your office phone system with all the individual settings that worker has on their phone at the office. Someone calls your office and the call automatically rings the phone at your worker's home. The caller doesn't know where the person they're calling is located. This arrangement can even work for a small one, two, or three person branch office.

• Easily and economically connecting traveling workers. Imagine you're traveling and staying at a hotel with a high speed Internet connection. You have a soft phone on your laptop computer. You can use a headset on your laptop or a handset that plugs into a USB port on your computer. The handset acts just like the handset on your phone at the office. You can now receive and make calls through your soft phone just like you're at your office. Callers will ring through to your soft phone.

You can be located anywhere in the world and the person you call or calls you won't know where you are. If you're going to be away for an extended period of time, you may even want to take a regular office phone and set it up on your Internet connection. This arrangement makes use of IP Telephony for your office combined with VOIP using the Internet. IP Telephony makes all this easily possible at a lower cost than traditional systems.

Home based and traveling workers can also go into your office, in fact any of your office locations, and simply "log in" to your phone system just like they log in to your computer system. Once logged in all their phone settings are automatically provided to the phone in which they log in. This just wasn't easy or feasible to do economically prior to IP Telephony.

• Enhanced contact center (call center) responsiveness to customer needs. Lowered costs through IP Telephony makes it economical to use multiple call centers for time zone coverage, lower labor market costs, and even overseas call centers for small and medium sized businesses.

I know the mention of overseas (in respect to the North America) labor may not be what some people want to hear but the reality is that large corporations have been using overseas labor for call centers, manufacturing, and technical skills for decades. Now, what was once only economical for large corporations is also economical for small and medium sized businesses. IP Telephony levels the playing field of business competitiveness.

• "Contact center" is the replacement term for what used to be "call center." Why? Is it really necessary to change the terminology? Of course, I think the answer is unequivocally "yes" or I wouldn't mention it. A Call Center was appropriately named because all it did was take phone calls.

Now a Contact Center using IP Telephony, since it uses IP technology just as the data network uses, can take phone calls, fax messages, e-mail, web text chat, web voice calls, and even web video calls, all at the same time, in the same queues for the contact center agents. Isn't the point of "customer service" to make it easy for the customer to contact you? What's better than letting the customer choose the means of contact? Now it's possible and affordable.

• Disaster recovery and power outage backup for business continuity. Redundant phone systems with automatic failover over dispersed locations is now economical. With the traditional phone system technologies it used to cost 70% - 100% of the original system cost to get redundant systems. In addition, the carrier services to make it happen were also costly.

Now it's possible to get redundant systems for just 10% - 30% of the original system cost. Additionally, the carrier services are also less expensive than previously. Business continuity planning is just like any other "insurance" you obtain for your business. All insurance is a trade-off between the cost of the insurance and the coverage level you obtain.

At some point paying too much doesn't reap enough extra benefit to warrant the extra cost. On the other hand, paying too little and not obtaining meaningful coverage doesn't make sense either. With the costs for obtaining business continuity so dramatically lower than previously, it could make sense to make it a part of your total insurance and risk management for your business.

• Using one cabling infrastructure to carry both data and voice traffic instead of separate cabling infrastructure for each. This can have significant cost savings especially if you are moving your office or setting up a new office. In either of these situations you will have a substantial cost savings by only having to install your network cabling and not having to install a separate cabling system for your phone system.

• Simplified system administration through a GUI (graphical user interface). You can make changes to your system that previously required your telephone equipment vendor to make the changes. Therefore, you can significantly reduce your maintenance costs.

• Easier moves of telephone sets. When moving from one location in your building to another, it previously required re-programming the telephone switch and physically changing some wires in the "telephone closet." With IP Telephony as you pack up your desk supplies and plants, you also grab your telephone. In your new location, you simply plug the telephone into the Ethernet connection in the wall and then connect your computer to a jack in the phone that acts as a bypass for your data. All your personal settings move with you. Costs for moves are dramatically reduced.

• Software upgrades are easier and can be performed by you instead of paying the telephone equipment vendor to do them.

There are many more benefits to IP Telephony but this brief overview should be enough to peak your interest to continue your investigation. You don't need to make a total swap out of your current phone system. It is possible to gradually introduce an IP Telephone System into your organization and interface it to legacy systems.

By Dominic Grewal

In addition to this brief explanation, you might want to further discuss the strategic business applications and implications of IP Telephony. New technologies such as IP Telephony don't just replace previous ones but allow much greater functionality, increased productivity, enhanced customer service and lower costs than prior technologies.

Don't just improve the way you currently do business! Expand the possibilities of conducting your business in ways you never thought possible. All major phone system manufacturers are investing their research and development dollars into development of their IP Phone Systems. Hundreds of companies have already converted to it. There must be a reason or two or twenty.

MemoryCard that Equal with HardDisk

noreply@blogger.com (Kurt Donie Cobain) — Mon, 22 Oct 2007 04:55:00 +0000

Panasonic 32 Gb SDHC
Panasonic launch a memorycard 32GB SDHC on CEATEC 2007 fair, they claimed that hardware could saved file HD video capacity. In that opprtunity they shown that hardware ability in write and read data speed. As we known before, SDHC is new format from SD card, where SDHC ( Secure Digital High Capacity, SD 2.0), own 2 GB minimum capacity. SDHC used FAT32 file system that supported data density higher if compared with FAT16(10).
file size still like with SD, but they used SD 2.0 standart and SDHC use different memory addressing methode, and theoritically in this methode SDHC can reach 2048GB capacity. SDHC card just work on hardware that SDHC support, but old SD still can used on SDHC hardware.

Digital Music File Format

noreply@blogger.com (Kurt Donie Cobain) — Sun, 21 Oct 2007 09:12:00 +0000

MP3
from MPEG, Audio layer 3, MP3 become most popular in music digital. Because it have small file size and it have as good as Audio CD. This format is developed by Fraunhofer Institute. With 128 kbps bitrate, MP3 file have good quality, but MP3 pro-format as MP3 generation offering same quality with half bitrate from MP3. MP3 pro compatible with MP3. MP3 player can play MP3 Pro but not as good as MP3 Pro player.

WAV
The results of CD ripping recorded from this format before formatted to another format, but this step now skipped because this format have big filesize.

AAC
Advanced Audio Coding this format is standart Motion Picture Experts Group (MPEG) part, since MPEG-2 is use on 1997, they offer sample rate till 96 KHz- twice from MP3. This format used by Apple on their online music store iTunes. Music quality in this format is good enough even in low bitrate. iPod, portable digital music player from Apple, is the most popular that support this format.

WMA
This format is the most format that online music vendor, because they support with Digital Rights Management (DRM). DRM is a fiture that stop music hijack thing that affraid of music studio at this time. Music qulity that WMA offer is better than MP3. and also AAC. This format is enough popular and most of general hardware and software support in this file format.

Ogg Vorbis
This is the only one free file formatand open source. The other file format above generally have a copyrighted and software developer must pay for license for product that played in this file format. From quality side is high quality on low bitrate compare with another file format.

RealAudio
One of format that ussually found on low bitrate, this format from Realnetworks ussually used on audio streaming on up to 128 kbps, RealAudio used standart AAC MPEG-4

MIDI
This format is fit for sound that result from synthesizer or another electronics hardware, but it doesnt match from analog sound convertion because not too accurate. File in this format have small file size and lately used on phonecell ringtones.

Symmetric Transmission vs. Asymmetric Transmission

noreply@blogger.com (Kurt Donie Cobain) — Thu, 18 Oct 2007 08:33:00 +0000

Data transmission is symmetric if the data in the downlink and the data in the uplink is transmitted at the same data rate. This will probably be the case for voice transmission - the same amount of data is sent both ways. However, for internet connections or broadcast data (e.g., streaming video), it is likely that more data will be sent from the server to the mobile device (the downlink).

FDD transmission is not so well suited for asymmetric applications as it uses equal frequency bands for the uplink and the downlink (a waste of valuable spectrum). On the other hand, TDD does not have this fixed structure, and its flexible bandwidth allocation is well-suited to asymmetric applications, e.g., the internet (see this PDF file for more details). For example, TDD can be configured to provide 384kbps for the downlink (the direction of the major data transfer), and 64kbps for the uplink (where the traffic largely comprises requests for information and acknowledgements). See this PDF file for more details.

TDMA vs. CDMA

noreply@blogger.com (Kurt Donie Cobain) — Thu, 18 Oct 2007 08:31:00 +0000

We have considered how a mobile phone can send and receive calls at the same time (via an uplink and a downlink). Now we will examine how many users can be multiplexed into the same channel (i.e., share the channel) without getting interference from other users, a capability called multiple access. For 3G technology, there are basically two competing technologies to achieve multiple access: TDMA and CDMA.

TDMA is Time Division Multiple Access. It works by dividing a single radio frequency into many small time slots. Each caller is assigned a specific time slot for transmission. Again, because of the rapid switching, each caller has the impression of having exclusive use of the channel.

CDMA is Code Division Multiple Access. CDMA works by giving each user a unique code. The signals from all the users can then be spread over a wide frequency band. The transmitting frequency for any one user is not fixed but is allowed to vary within the limits of the band. The receiver has knowledge of the sender's unique code, and is therefore able to extract the correct signal no matter what the frequency.

This technique of spreading a signal over a wide frequency band is known as spread spectrum. The advantage of spread spectrum is that it is resistant to interference - if a source of interference blocks one frequency, the signal can still get through on another frequency. Spread spectrum signals are therefore difficult to jam, and it is not surprising that this technology was developed for military uses.

Finally, let's consider another robust technology originally developed by the military which is finding application with 3G: packet switching.
