noreply@blogger.com (Mechanical Sky) — Fri, 06 Feb 2009 04:11:00 +0000

World most viewed game is so much entertaining, even advertisements broadcasted for this show have budget in millions. Next interesting thing is that most of these vidoes are made by engineering and drafting softwared "AutoCad". Bud Light Lime's Sphere of Summer or Thugs, a commercial for a Denny's campaign in Super Bowl XLIII, Autocad was used. Even movie trailer for Start Trek used this software. Mostly they use Autodesk Maya 3D modeling, animation and rendering software and Autodesk Inferno visual effects software. Coca Cola's Heist, Kellogg's Plant a Seed as well as Fandamonium for Monster.com. All were created with Maya. Include adds from Cash4Gold, Chase for Audi, Career Builder and Ladder, they were all used in Autodesk. The most loved add drinkability beer budweiser was made in Autodesk too.
Basically Autodesk, Inc., is a world leader in 2D and 3D design software for the manufacturing, building and construction, and media and entertainment markets. Since its introduction of AutoCAD software in 1982, Autodesk has developed the broadest portfolio of state-of-the-art Digital Prototyping solutions to help customers experience their ideas before they are real.

World's slimmest TV - Just a quarter inch thick

noreply@blogger.com (Mechanical Sky) — Mon, 05 Jan 2009 19:02:00 +0000

Now we can have TV which is just a quarter inch thick. It is thinner than mobile set. News released by AFP states: South Korea's Samsung Electronics on Monday unveiled what it says is the world's slimmest LCD (liquid crystal display) TV.
The new product, measuring only 6.5 millimetres (0.26 inch) thick, is thinner than any other existing TV set, and even slimmer than most mobile handsets, Samsung said in a statement.
Its thickness is one seventh of Samsung's "Bordeaux 850" LCD TVs, which is currently the thinnest on the market, the company said.
The new product, which adopts an LED (light emitting diode) backlighting system, will be on display at the 2009 Consumer Electronics Show in Las Vegas from January 8 to 11, Samsung added.
Samsung is the leader, who is the follower time will tell us. Till then lets wait till january 8 for the show in Las Vegas.

Solar Car

noreply@blogger.com (Mechanical Sky) — Sat, 03 Jan 2009 08:00:00 +0000

Why are we burinng gas? Aren't we emptying earth's gasoline tank? Probably we should tap the unlimited ray of sun. or moon or even stars? why don't anyone bring this? If we can drive giant satelitte, obviously we can drive tiny car.
Just today Toyota Motor is in news. They have started producing solar panels. Though it is limited to their own manufacturing plant, expert says these pannel may be used for future solar vehicle. Today report of Toyota developing solar powered green car is all over the place. Toyota has already begun using solar panels at its Tsutsumi plant in central Japan to produce some of its own electricity.
The solar panels on the roofs add up in size to the equivalent of 60 tennis courts and produce enough electricity to power 500 homes, according to Toyota. That reduces 740 tons a year of carbon dioxide emissions and is equal to using 1,500 barrels of crude oil.
Conclusion: Toyota is also likely to indirectly gain expertise in solar energy.
And probably GM,Ford,Chevy,Honda are secretly doing reseach too, who knows!

New Fastener Glitches Slow the Dreamliner Again

noreply@blogger.com (Mechanical Sky) — Wed, 17 Dec 2008 04:19:00 +0000

Oops! it happened again......nut and bolt. yeah very little thing to hold two pieces together again slow down the production of deamliner. Itgonna be dream again for Boeing. This time not only fastener delayed their schedule, they are having trouble attachng structres.
In the most recent glitch, a pressurization test on a Dreamliner fuselage revealed a small gap under the heads of thousands of fasteners. The problem occurred on the floor grid and other structures installed inside the fuselage shell where titanium was fastened to carbon fiber composite. This means they have to replace thousands of fasteners. Currently 12 dreamlines are in production assembly. Earlier the productionof dreamlined was delayed because of fastener supplier. This time it is their design glitch. They didn't define the specification of attachingtitanium to the compoisite shell. The specifications were developed by Boeing engineering staff.
Here is the engineering description of fastener specificaton:Cadmium coatings are applied to ferrous and nonferrous metals to provide resistance to corrosion. Like zinc, cadmium also provides sacrificial protection to a substrate such as steel by being preferentially corroded when the coating is damaged and small areas of the substrate are exposed. Electroplating accounts for more than 90 percent of all cadmium used in coatings and is normally specified in thicknesses between 10 and 30 microns.Because of incorrect specification now some of the fasteners are not flush and some have gap between the structre and the head of the fastener.Beoing has stated the problem as"fastener with incorrect length"

Braintstroming

noreply@blogger.com (Mechanical Sky) — Thu, 11 Dec 2008 02:45:00 +0000

What is brainstroming? Strom your brain to and froth to get a solid a result. This is my definition. If you look at wekipedia, you will find this:
"Brainstorming is a group creativity technique designed to generate a large number of ideas for the solution to a problem. The method was first popularized in the late 1930s by Alex Faickney Osborn in a book called Applied Imagination. Osborn proposed that groups could double their creative output by using the method of brainstorming."
Brainstorming is generally done in a group to produce effective technique. It is an excersie of brain. Basic norms of brain stroming are: Focus on the task, bring all kind of ideas and concluded with best ideas.
Brainstroming is not only fun but it has a lot of benefit too. Here are 8 tips for brainstroming.
1. Use brainstorming to combine and extend ideas, not just to harvest ideas.
Andrew Hargadon's How Breakthroughs Happen shows that creativity occurs when people find ways to build on existing ideas. The power of group brainstorming comes from creating a safe place where people with different ideas can share, blend, and extend their diverse knowledge. If your goal is to just "collect the creative ideas that are out there," group brainstorms are a waste of time. A Web-based system for collecting ideas or an old-fashioned employee suggestion box is good enough.

2. Don't bother if people live in fear.
As Sigmund Freud observed, groups bring out the best and the worst in people. If people believe they will be teased, paid less, demoted, fired, or otherwise humiliated, group brainstorming is a bad idea. If your company fires 10% of its employees every year, for instance, people might be too afraid of saying something "dumb" to brainstorm effectively. It is better to have them just work alone.

3. Do individual brainstorming before and after group sessions.
Alex Osborn's 1950s classic Applied Imagination, which popularized brainstorming, gave advice that is still sound: Creativity comes from a blend of individual and collective "ideation." Skilled organizers tell participants what the topic will be before a brainstorm. I once went to a session on how to give an "itch-less haircut," and, at the suggestion of the organizer, took a preliminary trip to a salon where I asked the stylist for a cut as "itch-free as possible" to jumpstart my thinking. At the brainstorm, I reported how tightly the stylist wrapped the cape around my neck and how she put talcum powder all over me—effective, if uncomfortable and messy measures.

4. Brainstorming sessions are worthless unless they are woven with other work practices.
Brainstorming is just one of many practices that make a company creative, and it is of little value if it's not combined with other practices—such as observing users, talking to experts, or building prototype products or experiences—that provide an outlet for the ideas generated. Some of the worst "creative" companies that I've worked with are great at coming up with new ideas, but never actually get around to implementing them. A student and I once studied a team that spent a year brainstorming and arguing about a simple product without producing even a single prototype, even though a good engineer could have built one in an hour or two. The project was finally killed when a competitor came out with the product.

5. Brainstorming requires skill and experience both to do and, especially, to facilitate.
In all of the places that I've seen brainstorming used effectively—Hewlett-Packard, SAP's Design Services Team, the Hasso Plattner Institute of Design at Stanford (or "The d.school"), the Institute for the Future, Frog Design, and IDEO—brainstorming is treated as a skill that takes months or years to master. Facilitating a session is a skill that takes even longer to develop. If you hold brainstorms every now and then, and they are led by people without skill and experience, don't be surprised if participants "sit there looking embarrassed, like we're all new to a nudist colony," as one manager told The Wall Street Journal. That is how humans act when they do something new and have poor teachers.

6. A good brainstorming session is competitive—in the right way.
In the best brainstorms, people feel pressure to show off what they know and how skilled they are at building on others' ideas. But people are also competitive in a paradoxical way. They "compete" to get everyone else to contribute, to make everyone feel like part of the group, and to treat everyone as collaborators toward a common goal. The worst thing a manager can do is set up the session as an "I win, you lose" game, in which ideas are explicitly rated, ranked, and rewarded.

A Stanford graduate student once told me about a team leader at his former company who started giving bonuses to people who generated "the best" ideas in brainstorms. The resulting fear and dysfunctional competition drastically reduced the number of ideas generated by what had been a creative and cooperative group just weeks earlier.

7. Use brainstorming sessions for more than just generating good ideas.
Brainstorms aren't just a place to generate good ideas. At IDEO, these gatherings support the company's culture and work practices in a host of other ways. Project teams use brainstorms to get inputs from people with diverse skills throughout the company. In the process, a lot of other good things happen. Knowledge is spread about new industries and technologies, newcomers and veterans learn—or are reminded—about who knows what, and jumping into a brainstorm for an hour or so to think about someone else's problem provides a welcome respite from each designer's own projects. The explicit goal of a group brainstorm is to generate ideas. But the other benefits of routinely gathering rotating groups of people from around a company to talk about new and old ideas might ultimately be more important for supporting creative work.

8. Follow the rules, or don't call it a brainstorm.
This is true even if you only hold occasional brainstorms and even if your work doesn't require constant creativity. The worst ""brainstorms"" happen when the term is used loosely, and the rules aren't followed—or known—at all. Perhaps the biggest mistake that leaders make is failing to keep their mouths shut. I once went to a meeting that started with the boss saying, "Let's brainstorm." He followed this pronouncement with 30 minutes of his own rambling thoughts, without a single idea coming from the others in the room. Now that's productivity loss
