GATE-2011 Question

char c[] = "GATE2011";
char *p = c;
printf("%s", p + p[3] - p[1]);
output is :2011
explanation:
p[3] is 'E' and p[1] is 'A'.
ASCII VALUE OF E is 37
ASCII VALUE OF A is 33
so 37-33=4

p[3] - p[1] = ASCII value of 'E' - ASCII value of 'A' = 4
So the expression p + p[3] - p[1] becomes p + 4 which is base address of string "2011"

main()
{
int a=- -4;
printf("a=%d",a);
getch();
}

output: a=4;

Explanation:Here unary minus (or negation) operator is used twice. Same maths rules applies, ie. minus * minus= plus

Note: However you cannot give like --4. Because -- operator can only be applied to variables as a decrement operator (eg., i--). 4 is a constant and not a variable

2011-08-22T12:03:00.001+05:30

main()
{
int i=3;
switch(i)
{
default:printf("zero");
case 1: printf("one");
break;
case 2:printf("two");
break;
case 3: printf("three");
break;
} }
output :three
Explanation :The default case can be placed anywhere inside the loop. It is executed only when all other cases doesn't match.

void main()
{
static int i;
while(i<=10)
(i>2)?i++:i--;
printf(“%d”, i);
}
output:32767

Explanation:Since i is static it is initialized to 0. Inside the while loop the conditional operator evaluates to false, executing i--. This continues till the integer value rotates to positive value (32767). The while condition becomes false and hence, comes out of the while loop, printing the i value

2011-08-22T11:49:00.002+05:30

main()
{
int i=5;
printf(“ %d ”,i=++i ==6);
}

Output : 1

The expression can be treated as i = (++i==6), because == is having higher precedence than = operator so in the inner expression, ++i is equal to 6 yielding true(1). Hence the result is 1

1. Given a collection of points P in the plane, a 1-set is a point in P that can be separated from the rest by a line, .i.e the point lies on one side of the line while the others lie on the other side.
The number of 1-sets of P is denoted by n1(P). The minimum value of n1(P) over all configurations P of 5 points in the plane in general position(.i.e no three points in P lie on a line) is

a)3 b)5 c) 2 d)1
Ans: 5

2. The citizens of planet nigiet are 8 fingered and have thus developed their decimal system in base 8.

a)1 b)3 c)4 d)0

4. Hare in the other. The hare starts after the tortoise has covered 1/5 of its distance and that too leisurely3. A hare and a tortoise have a race along a circle of 100 yards diameter. The tortoise goes in one direction and the. The hare and tortoise meet when the hare has covered only 1/8 of the distance. By what factor should the hare increase its speed so as to tie the race?

a) 37.80 b)8 c) 40 d) 5
Ans: 37.80

5. Here 10 programers, type 10 lines with in 10 minutes then 60lines can type within 60 minutes. How many programmers are needed?

a) 16 b) 6 c) 10 d) 60
Ans: 10

This type of Q's repeated 4times for me but values are different.

6. Alok and Bhanu play the following min-max game. Given the expression
N = 9 + X + Y - Z

Where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu
would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be

a) 0 b) 27 c) 18 d) 20

The Q's concept is same but the equation of N's is changing.

7. Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack.

Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 = i = 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game. Initially, the gold coinis the third coin from the top. Then

a) In order to win, Alice's first move should be a 1-move.
b) In order to win, Alice's first move should be a 0-move.
c) In order to win, Alice's first move can be a 0-move or a 1-move.
d) Alice has no winning strategy.
Ans: d

A turn consists of moving the coin on the top to a position i below the top coin (0 ≤ i ≤ 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it's a player's turn then the player wins the game.

Initially, the gold coinis the third coin from the top. Then

In order to win, Alice's first move should be a 0-move.
In order to win, Alice's first move should be a 1-move.

Pattern 2:

1. There are two water tanks A and B, A is much smaller than B. While water fills at the rate of 1 liter every hour in A, it gets filled up like, 10, 20, 40, 80, 160 in tank B. (At the end of first hour, B has 10 liters, second hour it has 20 liters and so on). If tank B is 1/32 filled of the 21 hours, what is total duration of hours required to fill it completely?
a) 26 B)25 c)5 d)27

Solution: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8)th part in 23 hours,(x/4)th part is filled in 24 hours,
(x/2)th part is filled in 25 hours, (x)th part is filled in 26 hours
So answer is 26 hours.

Cloud computing to create one lakh jobs in India: Study

2011-07-20T11:53:00.000+05:30

Indo Asian News Service, On Tuesday 19 July 2011, 10:24 PM

Bangalore, July 19 (IANS) As the next technology wave, cloud computing by enterprises has the potential to create about 100,000 new jobs in India, a study said Tuesday.

'Of the projected $4.5-billion total cloud computing market in India by 2015, private cloud will account for $3.5 billion, generate about 100,000 additional jobs and save about 50 percent of cost of IT operations for Indian enterprises,' the study 'Private Cloud Landscape in India', by Zinnov Management Consulting and global IT firm EMC Corporation, revealed.

In cloud computing, multiple servers are used as a single platform through a digital network (website) under secured environment with access to a range of applications and tools for reducing the cost of IT operations.

Cloud computing is emerging as the next big IT service for its pay-as-you-go model, which eliminates capital intensive investment by companies, especially small and medium enterprises (SMEs) in setting up IT infrastructure.

Spend on using cloud by information technology and back office firms, telecos, BFSI (banking, financial services and insurance), manufacturing and government organisations is set to increase to 8.2 percent over the next five years from 1.4 percent in 2010.

'There will be an increased preference of cloud adoption over the next five years in India. The total cloud market, which was about $400 million in 2010, is expected to growth by a whopping 60 percent annually with private cloud dominating the landscape,' Zinnov chief executive Pari Natrajan told reporters here.

Though vendors with partnerships are better positioned to address enterprise needs, the survey noted that many Indian firms would have to invest in competency building to take advantage of cloud computing technologies as they were under-skilled in meeting the growing requirement.

'Cloud computing will reshape the Indian IT market by generating new opportunities for vendors and driving changes in traditional IT offerings,' Natarajan pointed out.

Companies and organisations, which have not adopted IT so far or invested in data centres and server farms will have the advantage of directly moving to the low-cost cloud model.

'For cloud computing to deliver its promise, customers need human resources with cloud computing competencies, both as vendors or as internal resources. Though there are vendors such as ours (EMC) offering the solution to customers for making informed decisions, we need to build competencies to leverage cloud computing technologies,' EMC India president Manoj Chugh said on the occasion.

The findings are based on a survey of over 100 chief information officers (CIOs) and IT decision-makers in India across industry verticals conducted during January-May 2011

how to make online money 20 ideas.

2011-02-08T09:36:00.001+05:30

A cash cow for the enterprising, the Internet is littered with opportunities to make a fast buck. While it rarely qualifies as a solitary source of income, the Net can easily help you supplement it. However, the amount you earn depends on the time and effort invested. Go through these 20 options and find out which ones work for you.
Blogging
If you're a passionate closet writer who wants to be published but can't find a way to do so, make each keystroke your way to wealth by penning your own blog. Starting a blog doesn't require extensive technical skills but it's important that you have expertise in the field you are writing on. This will attract visitors to your site. Building a large following will enable you to earn profit by luring advertisers, writing paid reviews or getting commissions for promoting other people's products.

Paid Writing
If maintaining a blog is difficult for you but you still want to indulge your passion for writing, you can jot down articles for other blogs or sites such as Weblogs, Helium or PayPerPost. Writing an e-book can also be a good option. E-books are investment free, with no cost for printing and shipping. If you have a strong command over languages, you can become a copy editor, where Webmasters will pay you to read articles and correct grammatical errors, sentence fragments, etc.

e-tuitions/Webinars
The demand for tutors is high and growing. So, if you like helping others learn, e-teaching could be the earning ticket for you. All you need to become an online tutor is expertise in your subject and a few spare hours per week. TutorVista, e-tutor, SmartThinking and Tutor.com are some of the sites you can enroll with. If you gain a good reputation as a coach, you could even conduct Webinars-lectures or seminars transmitted over the Net. College and university students are willing to pay to gain entry to a well-respected Webinar.

Affilliate/Reseller
For those who have the knack of selling, one of the best ways to make money online is to become an affiliate/reseller. An affiliate is a person who gets a commission for selling every product that he promotes, whether on his Website or through any other avenue such as eBay. You don't have to own the product. You only need to sign up for an affiliate program with a company and start selling its products under your referral link. Firms such as Commission Junction or Click Bank have a large pool of products.

Buying/Selling domains
Buying and selling domain names is another way to make money from home and requires very little investment or time. You can buy domains at their registration prices or even cheaper and trade them at a profit. However, always research on sites such as sedo.co.uk, afternic.com, ebay.com or other domain auction sites to get an estimate of the hottest selling names. The best way to find good ones is to use terminated domain lists, which contain several expired names that are back in the pool.

Freelancing for Professionals
Freelancing is a great option for professionals who are experts in their respective trades and know how to ensure customer satisfaction. Various freelancing and project-oriented sites allow companies that need help to describe their projects. Freelancers and small businesses offer bids, ideas or proposals, from which the buyers can choose what they find most suitable. Websites such as Elance cover everything from programming and writing to data entry and design, while RentACoder focuses on software programming.

Advertising
You can sell space on your Website or blog for advertisements and you earn when these ads are clicked by visitors to your site. The sorting and placing of ads is free. The profitability of pay-per-click advertising depends on the traffic level of the Website and, most importantly, on the clickthrough rate and cost per click. Google AdSense is the most popular option, while others are BidVertiser, Text Link Ads and Blogads. Direct banner and RSS feed are some other forms of online advertising.

GPT Programme
GPT or Get-paid-to sites are becoming increasingly popular among teens. You get paid for signing up for free Websites, newsletters, playing games and filling out online surveys. These are suitable for people who don't have a skill set but want to earn extra money. Taking online surveys is simple- register with a few legitimate, paid survey sites and answer questions. The topics range from shopping to politics. This might not help you make a living, but you can earn good pocket money. Contests2win is one of the trusted GPT Websites.

Online Marketing
Once a Website is created and optimised for search engine (SEO), the SEM or Search Engine Marketing begins. A treasure trove lies hidden here. An SEO/SEM expert, who is responsible for marketing a Website, can promote it in various ways. These include article marketing, writing press releases, forum posting, blog posting, submitting your site to directories and search engines, social bookmarking, etc. Most companies don't do this in-house and pay you to conduct the SEM for them.

Making themes
As more and more people seek an online presence, the demand for Website templates and WordPress (Blog) themes will keep increasing. If you are good at Web designing and coding, you can earn a lot from designing Web themes. In this segment, there are mainstream Websites, such as TemplateMonster and ThemeForest, which act as a marketplace where you can sell your themes. Templates are sold and priced depending on the rights and features that are bundled with them.

Selling photos
If you enjoy photography and are good with a camera, you could be sitting on a huge reserve of revenue. There are people who will be interested in your collection of images. Nowadays, it's easy to take your photos to the public, providing a convenient way to build a secondary income stream. Many stock photo agencies, such as Fotolia, Dreamstime and Shutterstock, offer incentives for people to earn from their photos.

Support & service
Providing coding or fixing other Webmasters' issues is another great way to earn extra bucks. There are simple jobs ranging from adding a script to setting up sites, but knowledge of Web coding is essential. One can offer support for Web CMS (content management systems) like Drupal or Joomla. After you are comfortable with your own installation, you can help other people to set these up and configure them.

Stock/forex trading
Joining the stock/forex market may seem a bit risky. However, you can start small and continue researching till you gain experience in this area. Once you do, it will be easy to earn from exchanging foreign currencies and/or stocks. Their rates fluctuate depending on supply and demand, and economic and political influences in the world. The aim of any trader is to spot which currency/stock is likely to rise or fall in value against another. The more time you put in, the more you will earn.

Selling your own brand
If you have a flair for designing cool images, don't bother about creating your own inventory. As long as your design can be printed on a product, you can pocket some money. You can upload designs on various Websites such as CafePress, and if somebody orders these designs, the company will print them and distribute the products. It could be designs for T-shirts, hats, bags, books, posters, calendars, greeting cards, etc. You will receive a commission for each sale. Other such sites include Lulu and Zazzle.

Virtual Assistant
Small businesses always need help in running their processes, but may not be willing to hire a full-time employee. As a virtual assistant, you are expected to perform practically any administrative task that a traditional secretary or assistant would, such as make travel reservations, handle expense reimbursements or pay bills. You can do it from the comfort of your home, interacting with clients either online or by phone. Your expertise will decide how much moolah you rake in.

Inbound call centre
Many companies, who are facing space constraints, especially those in metro cities, prefer to hire workers outside their offices or outsource certain processes. You can set up an inbound call centre at home to handle such jobs. Research different companies that are outsourcing their work as they may have opportunities for inbound call centre agents. You can work for more than one company. This can be either a part-time or fulltime engagement, depending on your need.

You Tube
If there's a dramatic performer hidden inside you who craves applause and adulation, upload yourself on YouTube. You can be a filmmaker, musician or comedian who wants a wider audience. Your earnings will come from ads displayed on your video page. This process is similar to the pay-per-click advertising program common to other Websites and blogs. Sites such as Flixya and Mediaflix can be helpful in this regard.

Researching for others
Don't be morose if you can't write, design or code. Lack of talent cannot stop you from making money online. If you're willing to work hard for a few hours a week, you can take up simple research jobs for other people who don't have the time to do it themselves. You could search for opportunities in organisations that provide funding for research and offer to assist them through online investigation.

Building Applications
With smartphones gaining popularity, the demand for their applications, or apps as they are popularly known, has also shot up. There are over 3 million apps for the iPhone and over a million apps in Google's Android market. Most of these are selling like hot cakes. Developing and selling your own smartphone app is becoming a lucrative way to make money on the Internet. Apps cost virtually nothing to develop and entail no storage or shipping costs. So they enjoy the best profit margins.

Transcription
Medical transcription involves making written copies of oral material dictated by doctors or other medical experts. These may include history and physical reports, clinical notes, consultation notes, reports, letters, psychiatric evaluation and so on. The dictated material needs to be transcribed swiftly and accurately, which is the most challenging aspect of the job. To become a medical transcriptionist, you need to have a good knowledge of medical terminology and a high typing speed along with accuracy.

How to switch - Rules:

a) Subscribers who want to avail of this service, first need to send an SMS: PORTyour mobile number to 1900 from their mobile. They will get an eight-digit alphanumeric code and an expiry date for that code from the current service provider. This code is called unique porting code, or UPC.

b) Then he needs to fill the application in a particular format and mention the new service provider, he would like to subscribe for.

c) The new service provider will collect the information about the user from the current operator. A time period of seven days will be taken for the complete transfer of mobile number to the network of the new mobile operator.

Don’t put your cell number on Facebook

2011-01-18T15:59:00.000+05:30

Sydney, Jan 17 (ANI): A security expert has warned that users should remove their home addresses and phone numbers from their Facebook accounts.

Graham Cluley said the website now gives third parties access to that information.

The website said in a blog post at the weekend that it would give developers of applications access to the contact information of users who install their apps.

"These permissions must be explicitly granted to your application by the user via our standard permissions dialogs. Please note that these permissions only provide access to a user's address and mobile phone number, not their friend's addresses or mobile phone numbers," the Sydney Morning Herald quoted Facebook's Jeff Bowen as saying.

However, Sophos security expert Cluley, has raised doubts over the move.

"You have to ask yourself - is Facebook putting the safety of its 500+ million users as a top priority with this move?" he said.

"It won't take long for scammers to take advantage of this new facility, to use for their own criminal ends."

Cluley advised that users should take personal info such as home addresses and mobile numbers off their pages.

"You can imagine, for instance, that bad guys could set up a rogue app that collects mobile phone numbers and then uses that information for the purposes of SMS spamming or sells on the data to cold-calling companies," he said. (ANI)

IT biggies vroom back on job street

2010-10-12T15:19:00.001+05:30

KOLKATA: For over two million software professionals in India recovering from last year’s recession blues, when employers trimmed payrolls and froze hiring, there’s finally some good news ahead.

According to software industry lobby Nasscom , India’s top IT firms, including Tata Consultancy Services , Infosys and Wipro , are set to hire nearly 90,000 this year, compared with only around 20,000 last year. For the first time since the global economic crisis forced IT companies to freeze hiring and shed jobs in December 2008, employment in the sector is now looking up.

Recruitment firms and HR honchos at leading IT firms say the sector has witnessed the highest-ever job creation in September, with staff strength growing over 50%, similar to pre-recession levels.

“This is the highest hiring growth recorded in the IT sector since recession. We expect similar momentum till November since companies will be required to complete their annual hiring plan before next year,” says E Balaji, director & president, Ma Foi Randstad. He estimates IT hiring to have grown 20-22% during August-September over the same period last year.

Till 2008, even a 15% attrition rate was conservative in an industry where some firms struggled to keep it below 20-30%. However, with lar GE customers like JPMorgan, Citibank and GE sending more projects to India and with firms such as IBM and Accenture under pressure to hire more in low-cost locations like India, the war for retaining and hiring talent is back.

Apart from looking to serve new projects with fresh recruits, companies are also beginning to build bench strengths for future business. “IT biggies are stocking up skills and training them in advance in anticipation of new contracts they are expected to bag in the near future,” said Pradeep Udhas, executive director and head of IT advisory, KPMG.

“Some of them are also expecting attrition, and hence a preventive measure. All major companies like TCS , Infosys, and Cognizant have exceeded their expected earnings levels,” he added. He expects the renewed hiring momentum to continue for another year.

MphasiS, which declared a manpower base of 38,275 in its last quarterly results when it added 1,156 employees, says there are currently more than 2,000 vacant positions within the company.

“We never stopped hiring even during the downturn. What is encouraging is that some of the other companies that ceased recruitment have again started hiring,” says MphasiS chief human resource officer Elango R.

Headhunters say recruitment in tier-I companies are at pre-recession levels, but they say it will still take some time to pick up in the mid-level as the market landscape has changed. However, they say specialist companies like those in product development, analytics and testing are still growing and so has recruitment in tandem.

“Recruitment may be back, but there is much more sanctity now,” says Ikya Human Capital Solutions MD Ajit Isaac. “Recruitment is much more planned now with a small bench. Companies are also much more disciplined and avoiding employees who frequently change jobs,” he says.

Interestingly, Mahindra Satyam, which is on a comeback trail, plans to recruit some 3,000 by February next year. The company, with some 27,000 employees on rolls, has been hiring fresh talent for the past few months now and has already added 3,000 people during May-July.

Eamcet 2010 web allotment results hit by SMS ban

2010-09-25T12:03:00.000+05:30

Hyderabad, Sept. 24: The decision of the Centre to extend the ban on bulk SMS services till September 29, on account of the Allahabad High Court verdict on the Ayodhya issue, will hit over 1.5 lakh Eamcet qualified students who are eagerly waiting to hear if they have been granted admission to the engineering colleges.

The students were to be informed of the details via SMS on September 25.

The department of technical education had made all the arrangements to send an SMS to each Eamcet student on Saturday specifying the college and course they were allotted in the recently concluded web-based counselling.

It had even entered into an MoU with BSNL for the purpose.

The results will now be sent via e-mail to students’ personal IDs. But another problem is that a majority of students from rural areas do not have e-mail IDs.

“The seat allotment results will be mailed to each student. Those who have not provided e-mail IDs can know the results by visiting the Eamcet website,” said Mr Raghunath, camp officer, Eamcet admissions.

This is the first time that SMS was used for various purposes for the Eamcet, such as communicating the location of exam centres and announcing the exam marks and ranks.

Nearly 70% students of JNTUH fail 1st year B.Tech first year exams(2009-10)

2010-08-06T13:00:00.002+05:30

HYDERABAD: Of the 90,000 students who enrolled into JNTU-affiliated engineering colleges last year, 62,000 failed in their first year engineering exam, the results of which were declared on Wednesday. The exams were held in May. “So much for this craze to become engineers,” said an analyst.

Officials from JNTU said that over 40 colleges in Hyderabad and Ranga Reddy districts have got a pass percentage less than 10. Also over 25 per cent of the students who failed the examinations scored less than 10 percent in aggregate.

D N Reddy, JNTU vice chancellor, however, said that the pass percentage of first year students is poor this year as proper instruction had not happened in classrooms in the academic year 2009-10. “The number of working days were far less than 180 due to several reasons including political ones,” he said.

According to JNTU rules, the failed candidates will have to write supplementary and clear the test before appearing for second year examinations.

When asked about the reasons for low pass percentage, JNTU officials said that the downward slide in the pass percentage is due to an increase in the number of students taking admission in engineering colleges.

“Even students who get poor ranks in Eamcet take admission in engineering colleges as there is no dearth of seats. And the number of engineering colleges have increased multifold by the year leading to a decline in the quality of education. Both factors have contributed to poor percentage in final year results,” said Dr K Ramamohan Reddy, controller of examinations, JNTU-Hyderabad.

2010-05-11T10:03:00.001+05:30

Mon, May 10 03:15 PM
Washington, May 10 (ANI): An expert in online privacy has drawn attention to the five dangers of sharing information on social networking site Facebook.

Joan Goodchild, senior editor of CSO (Chief Security Officer) Online, claims marketing efforts by the company often results in a compromise on account holders' privacy, reports CBS News.

Goodchild noted five risks of using Facebook on 'The Early Show on Saturday Morning.' They are:

1.Your information is being shared with third parties

2. Privacy settings revert to a less safe default mode after each redesign

3. Facebook ads may contain malware

4. Your real friends unknowingly make you vulnerable

5. Scammers are creating fake profiles

India Today::Why foreign institutes dig Indian market

2010-03-19T13:52:00.000+05:30

For foreign universities, which haven't yet recovered fully from the aftershocks of the worldwide recession, India presents, to quote a word re-introduced into the English vocabulary by Tim Burton's Alice in Wonderland , a 'frabjous' opportunity.

More than 100,000 students leave Indian shores annually to study at universities abroad. Their presence has made foreign universities wake up to the incontrovertible fact that there's another 'creamy layer' below these students abroad whose families are prepared to pay upwards of Rs 2.5 lakh a year for quality education.

International students are the economic mainstay of foreign universities, but these institutions are not in a position to meet the demand for the education they provide on their own campuses back home. This untapped market makes the business of overseas campuses that much more lucrative.

For over a decade, foreign universities have been lobbying hard for the passage of the Foreign Education Providers Bill, which has been a pet project of HRD minister Kapil Sibal. The most recent of these exploratory visits was that of Robert A. Brown, president of Boston University, who was in the Capital in January to plan collaborations with leading universities here.

He said there was an insatiable appetite for quality education in India and collaborations would mutually benefit both countries. US's Georgia Institute of Technology announced its plan to set up campuses in Hyderabad and Visakhapatnam as soon as the Bill gets Parliament nod.

Central Michigan University, meanwhile, has taken another route to plant its flag in India. It has been offering a collaborative MBA programme with the Jawaharlal Nehru Institute of Technology, Hyderabad, for the past five years.

Experts associated with these universities explain the economic logic of their plans for India: the proliferation of private institutions in the country-especially in engineering, medicine, management and law - that charged fees upwards of Rs 2.5 lakh a year was evidence of the vast market waiting to be tapped.

These institutions attract the second layer of the country's higher education market. These are students whose families can't afford foreign education (upwards of Rs 15 lakh a year), but want to be in the top four favourite streams.

India, according the now-defunct National Knowledge Commission, needs 1,500 universities, compared with about 350 now, to raise the enrollment numbers from 7 per cent of the population aged 18-25 to developed country averages.

But even before the Bill got the cabinet's nod, Indian universities had initiated the process of collaborating with their international peers to offer degrees or diplomas. A National University of Educational Planning and Administration (NEPA) report in 2008 pegged the number of these institutions at more than 130.

For Bangalore University vice- chancellor A. N. Prabhu Deva, collaboration is the way forward.

"It will help a higher education institution rise to the standards of its foreign partner," he says. But for this collaboration to become meaningful, says R. Govinda, NEPA V-C, teaching must go hand in hand with research. "Only then will quality education and foreign collaborations be meaningful," he says.

Either way, for foreign universities, this is a winwin situation. Narayanan Ramaswamy, executive director of the management consultancy KPMG, points to the "massive demand supply gap" driving the international higher education market.

Biometric ID cards for JNTUH students

2010-02-07T22:39:00.001+05:30

Students of affiliated colleges of Jawaharlal Nehru Technological University (JNTU) will now swipe their identity cards to mark their attendance. JNTU has advised the engineering colleges under its purview to give students biometric identity cards to record attendance.

JNTU authorities took this decision last week. It will be implemented from July. The university decided to introduce the new attendance system after the higher education department demanded a stricter attendance system.

The department had got complaints from parents that certain colleges were tampering with the attendance records of students. According to the parents, certain students were given full attendance while some were prevented from writing annual and semester exams due to attendance shortage.

“Once the attendance system is computerised the colleges will not be able to tamper with it. Students who get less than 65 per cent of attendance will not be allowed to write examinations,” said D N Reddy, vice chancellor, JNTU-H.He said that the attendance records would be maintained by the university till the students complete their course.

TCS announces new doctorate funding program to drive quality academic research

2009-11-30T09:43:00.001+05:30

Tata Consultancy Services (TCS), (BSE: TCS.BO, NSE: TCS.NS), a leading global IT services, business solutions and outsourcing firm, today announced a new program to encourage quality academic research and thereby increase the available faculty talent pool in India.

The company will fund 200 doctoral candidates over a period of five years to take up Phd programs in reputable academic institutions across the country. The “TCS Research Fellows” will pursue original research in various aspects of computer science. 40 doctoral or Phd candidates will be chosen as TCS Research Scholars every year from a number of reputable academic institutes through a process of selection conducted by TCS and the academic institutes.

Announcing the TCS Research Scholar Program on the sidelines of Sangam, TCS’ annual academic conclave, N Chandrasekaran, CEO and MD said, “At a time, when the introduction of new technologies are changing business models rapidly, there is an urgent need for more focused research to stay ahead of the learning curve. The TCS Research Scholars program will help enlarge the R&D agenda and encourage exploration of new ideas by funding candidates in doctorate programs”.

“TCS works with our academic partners through the year to examine ways of deepening our relationship. The TCS Research Scholars Program is a new initiative to take this engagement with academia to the next level, said Ajoy Mukherjee, Head Global HR. “By inducting 200 new Phd scholars into the academic eco-system over a period of five years, this initiative will also significantly enhance the pipeline of high quality faculty for colleges, apart from generating new ideas and honing research talent in the country.”

The new program will supplement existing TCS programs like the Academic Interface Program, which is a holistic initiative to enhance the quality of the emerging workforce across the globe by supporting students, faculty, institutes and government. The program engaged with 499 academic institutes in India and over 85 overseas during FY2009, conducting over 130 faculty development programs benefiting over 4,000 instructors and 400 workshops for over 52,000 students globally. Over 1300 students benefited from TCS internships and awards.

EIE — the new age multi-utility course :ALL THE BEST FOR EXAM

2009-11-17T18:19:00.001+05:30

Electronics and instrumentation engineers have a plethora of opportunities spread across a wide spectrum of industries in India and abroad. There are plenty of employment chances if one does a B.Tech. course in electronics & instrumentation engineering (EIE).

The B.Tech (EIE) degree course is an excellent hybrid course formulated from the electronics and instrumentation subjects leading to multifaceted opportunities that will otherwise be unavailable to those doing electronics and instrumentation courses separately.

A common thing now in the U.S. and U.K. is that their modern Electrical Engineering Departments have introduced hybrid courses, which are offered with course content drawn from any two basic courses from subjects like electronics, instrumentation, computer engineering and son on. There will be immense scope for research, patent and product realisation thanks to the seamless integration of these basic and time-tested subjects in a hybrid course.

Many modern universities in India and abroad nurture offer hybrid courses even at the risk of initial sluggishness in getting wider acceptance. Hybrid disciplines offer wide scope for innovation and stability since new areas for research will constantly emerge. The primary focus of electronics and instrumentation engineering is the development and implementation of electronic instruments and subsystems for the purpose of measuring, monitoring, and recording physical phenomena.

EIE graduates are needed almost in every industry — chemical, drugs & pharmaceuticals, aluminium, steel, mining & metallurgy, paper, textile, consumer electronics, space, defence R&D, remote sensing, aerospace, AAI, Indian Railways, nuclear power stations, power sector, etc.
