Awesome Science: Stirling Engine


A Stirling engine is a heat engine operating by cyclic compression and expansion of air or other gas, the working fluid, at different temperature levels such that there is a net conversion of heat energy to mechanical work. Or more specifically; a closed-cycle regenerative heat engine with a permanently gaseous working fluid, where closed-cycle is defined as a thermodynamic system in which the working fluid is permanently contained within the system, and regenerative describes the use of a specific type of internal heat exchanger and thermal store, known as the regenerator. It is the inclusion of a regenerator that differentiates the Stirling engine from other closed cycle hot air engines.
Here’s an experiment showing the stirling engine

5 Things We Want in the New Kindle Fire

Amazon Kindle Fire
Amazon today sent out invites for a press conference on Sept. 6, which very well might be a new line of Kindles including a new Kindle Fire $199.00 at Amazon.
The timing is right; the Kindle Fire was announced last September, and possibly more importantly, everyone's trying to get in ahead of the rumored iPad mini launch on Sept. 12.
September is looking quite busy indeed, with Nokia and Motorola phone releases on Sept. 5, the Amazon event on Sept. 6, and Apple on Sept. 12. (Wouldn't it be funny if Apple didn't release an iPad mini?)
The new Kindle Fire enters a much more competitive world for 7-inch tablets than the old one did. Even without Apple's participation, we've got the blockbuster Google Nexus 7, which runs the latest version of Android on significantly more powerful hardware than the Kindle Fire for the same $199 price.
Last month, All Things D, which cited sources familiar with Amazon's plans, said the new Kindle Fire will have a built-in camera. The updated Amazon tablet will also sport a much-improved display with 1280-by-800-pixel resolution, bigger than the current 1024-by-600 screen. There will also be an entirely new width-to-height ratio, again following the Nexus 7, ATD said.
So what can the new Kindle Fire do to be something other than a Nexus 7 clone? Here are five ideas.
A truly sunlight-readable screen. This has been my Kindle Fire dream since before the first one came out. LCD technology looks dim outdoors and can be tiring on the eyes. For years now, we've been hearing of alternative screen technologies like Pixel Qi and color e-ink that look just as good outdoors and in. But those technologies still haven't broken through, and All Things D describes just another LCD on this tablet.
Exclusive TV and movie deals. The Amazon event is happening in Santa Monica, which is an unusual place to throw tech product launches; typically, if something's launched there, it has a major movie, music, or TV component. Amazon could make waves by getting Prime streaming for in-demand movies and TV shows that aren't on Netflix or iTunes. It could even secure exclusive rights to rent out blockbuster movies before its competitors do. 
Exclusive games. The video game industry is also centered in LA, and some blockbuster, exclusive and big-name games could win people over to this tablet. Amazon's brand is about content more than it's about hardware. Let's bring the content.
WhisperNet browsing. Bundling in at least some 3G access - even if it's only to stream Amazon content - would set this apart from most tablets, which are generally sold Wi-Fi-only because people don't want to pay extra for a service plan. The ability to download anywhere was part of what made the Kindle so addictive, and the Nexus 7 just doesn't have it. Amazon's event is being thrown at an airport, so I see a possibility here - get it? Things that fly through the air and into the cloud?
Silk living up to its promises. Amazon's Silk browser was supposed to leverage Amazon's servers to deliver dramatically faster browsing than the competition, but it didn't end up showing much of an advantage. Super-fast Web browsing that doesn't use a lot of data (a la Opera Mini) could help Amazon win away Web fiends.
There's one thing I don't particularly want to see: a shift from a 7-inch Fire exclusively to a 10-inch model. While a 10-inch Amazon tablet has potential for magazines, comics, and movie watching, the 7-inch model is absolutely the right size for reading on the go. While adding a 10-inch model would be a good thing, that shouldn't be done at the expense of a top-notch 7-inch tablet.
We'll be at Amazon's event at 1:30 p.m. Eastern on Sept. 6 to bring you the news.

2012 CBSE passout students will have to appear for all the exams in improvement test

As per MHRD notification dated Aug 14 students who have appeared for their class XII in 2012 and wish to improve upon their performance can re-appear for their boards in 2013. The Central Board of Secondary Education and the state boards would make appropriate arrangements to facilitate this through a special dispensation.

“Everyone agreed to a second chance from next year,” said Vineet Joshi, chairperson of the Central Board of Secondary Education (CBSE). “But students will have to appear for all the exams.
The second chance is being given in view of the fact that a student’s performance in the board exams will now play a role in determining entry to the Indian Institutes of Technology (IITs), National Institutes of Technology (NITs) and other engineering colleges. However, the changes were announced in July this year, after the board exams ended.
There are many students who wish to improve their performance in one or two subjects but it doesn’t seem possible for now.
The Maharashtra state education board already allows students a second chance. A student who has appeared for exams in March can do so again in October, and vice versa. Students can choose the better performance. The board chairperson, S Jadhav, said he was not aware of the HRD ministry notification.

What is with IITians these days? One from IIT Kanpur ends life with poison

 V. Nehru 20, a native of Marlinga thanda in Nalgonda district committed suicide by consuming poison after his parents came to know about his dismissal on Wednesday. Nehru was terminated by his college due to poor performance in academics.

“It was four months back that Nehru’s admission was terminated by IIT Kanpur authorities after he failed to score prescribed marks in neither his first or second semester exams of first year engineering. After this development, Nehru returned to the city and was staying at a hostel in Kukatpally keeping his family in the dark about the development. They were under the impression that Nehru was in Kanpur,” said sub-inspector K Raghu Kumar.
Since four months after termination, Nehru was taking money from his parents and staying at the hostel in Kukatpally. However two days back, Nehru’s father Ramana, a farmer, learnt that his son had been staying at Kukatpally and not in Kanpur.
“On Wednesday, Nehru called up his brother Venkat and informed him about his decision to commit suicide after learning that his parents had found out the truth. Nehru might have committed suicide by consuming poison,” police added.

Some Apple, Samsung Devices Banned in Korea

 Apple, Samsung Infringed Each Other’s Patents, Seoul Court Says
 An Apple Inc. iPhone 4S smartphone, left, and a Samsung Electronics Co. Galaxy S III smartphone are arranged for a photograph in Seoul. 

Apple Inc. (AAPL) and Samsung Electronics Co. (005930) must stop selling some smartphones and tablet computers in South Korea and pay damages after a Seoul court ruled they infringed on each other’s patents.
Apple, maker of the iPhone, violated two Samsung patents related to mobile-data transfer technologies, the Seoul Central District Court said today. Samsung, the world’s largest mobile- phone maker, infringed one Apple patent related to a “bounce- back” touchscreen feature, though the Suwon, South Korea-based company didn’t copy the design of the iPhone, the court said.
Cupertino, California-based Apple must stop selling the iPhone 3GS, iPhone 4, iPad 1 and iPad 2, while Samsung must stop selling 12 products including the Galaxy S, Galaxy S II and Galaxy Tab, the court said in a statement. Apple must pay Samsung 40 million won ($35,000), and the Korean company must pay its U.S. rival 25 million won, the court said.
“The ruling is in line with what we had expected,” Im Jeong Jae, a Seoul-based fund manager at Shinhan BNP Paribas Asset Management Co., which oversees about $29 billion, said by phone today. “What’s important is how the verdict that’s coming out soon in the U.S. will affect other pending cases in places like Europe and Australia.”

Four Continents

Samsung didn’t have an immediate comment on the ruling, Nam Ki Yung, a Seoul-based spokesman for the company, said by phone. Two phone calls to Steve Park, a Seoul-based spokesman for Apple, went answered.
Shares of Samsung fell 1.1 percent to 1.273 million won at 2:07 p.m. in Seoul trading.
The sales bans take effect immediately, and the companies can ask the court to rescind them. Samsung generated 39 percent of revenue in South Korea in the quarter ended June 30, according to data compiled by Bloomberg. Apple, the world’s most-valuable company, garnered 23 percent of its sales (AAPL) in Asia- Pacific during the same period.
“These products all came out a while ago, so the actual impact won’t be big,” Kim Hyung Sik, a Seoul-based analyst at Taurus Investment Securities Co., said by phone. “The U.S. case is the important one. Even a neutral verdict there would be a victory for Samsung.”

California Trial

Apple and Samsung (AAPL) have sued each other on four continents since April, accusing each other of copying products, design and technology, even as they are bound by commercial deals involving components supply. At stake is the dominance of the smartphone market, estimated by Bloomberg Industries to be worth $219 billion last year, where Samsung and Apple are the world’s two biggest manufacturers.
Samsung sued Apple in April 2011 in Seoul, Tokyo and Mannheim, Germany, alleging the iPhone maker infringed the South Korean company’s patents. Apple countered with a suit in June. Samsung filed a separate suit in Seoul in March this year, as the dispute expanded to countries including the U.S., U.K. and Australia.
The two companies began a jury trial in U.S. federal court in San Jose, California, on July 30 to try Apple’s claims that Samsung copied its iPad and iPhone designs and Samsung’s counterclaims that it’s the victim of patent infringement by the U.S. competitor. The case is the first U.S. jury trial in the dispute.
In the last quarter, the South Korean company controlled 34.6 percent of the global smartphone market, followed by Apple with 17.8 percent, according to market researcher Strategy Analytics.

Competitors and Customers

In the U.S. trial, Apple is seeking $2.5 billion to $2.75 billion in damages for its claims that Samsung infringed four design patents and three software patents in copying the iPhone and iPad. Apple also wants to make permanent a preliminary ban it won on U.S. sales of a Samsung tablet computer and extend the ban to the South Korean company’s smartphones.
Samsung is seeking as much as $421.8 million in royalties that the company claims it’s owed for Apple’s infringement of two patents covering mobile-technology standards and three utility patents.
Lawyers for both companies made closing arguments on Aug. 21 ahead of jury deliberations.
Both sides have had legal victories. Apple won a U.S. court order on June 29 blocking sales of Samsung’s Galaxy Nexus smartphone, the first smartphone to use Google Inc.’s Android 4.0 operating system. The product has remained on the market as Samsung appeals the order to the Federal Circuit.
In November, Samsung won a battle in an Australian court that allowed customers to buy Samsung’s rival to the iPad.
The allegations over intellectual property contrast with the commercial ties that bind the two companies. Apple’s reliance on Samsung chips for its best-selling phones and tablets will be worth as much as $7.5 billion to Samsung this year, a 60 percent jump from 2011, according to estimates from Gartner Inc., an industry researcher based in Stamford, Connecticut.
Apple accounts for about 9 percent of Samsung’s revenue, making it the company’s largest customer, according to a Info Aspirants supply-chain analysis.

Awesome Science: Ferrofluid



A ferrofluid (portmanteau of ferromagnetic, and fluid) is a liquid which becomes strongly magnetized in the presence of a magnetic field.
Ferrofluids are colloidal liquids made of nanoscale ferromagnetic, or ferrimagnetic, particles suspended in a carrier fluid (usually an organic solvent or water). Each tiny particle is thoroughly coated with a surfactant to inhibit clumping. Large ferromagnetic particles can be ripped out of the homogeneous colloidal mixture, forming a separate clump of magnetic dust when exposed to strong magnetic fields.
Here is some cool video of demonstrations of  Ferrofluid

JEE 2013 – Mechanism to divide 1.5 lakh students into all categories still not clear

The ministry for human resource development (MHRD) issued its first ever notification on JEE-2013 for admissions to all centrally-funded technical institutes on August 14. Not all 1.5 lakh students shortlisted for JEE Advanced, from Joint Entrance Exam (JEE)- Main exam will be from open category.

The official notification released by the ministry of human resource development (MHRD) said the 1.5 lakh students who will qualify for the Joint Entrance Exam (JEE)-Advanced test will include students from all categories, but IIT faculty members are still not clear about how they will divide 1.5 lakh into open category and reserved categories.
Usually, IITs follow 15% reservation for SC, 7 and a half% for ST and 27% for OBC candidates. “We are not sure if they will divide 1.5 lakh into open category and reserved categories, or they would have some other mechanism for the cut-offs,” said a faculty member of IIT-Bombay.
