Responsibilities & Contributions

Everyone who is a part of the society needs to contribute something or the other towards the development & growth of the society.

VAYAM, as a company, was thought of, as an instrument for uplifting human resource & capital standards which exist through-out the country & to set the moral & ethical values straight which have diverted paths. India needs to be the singular destination for global requirements in future if it has to stand up on its feet.

VAYAM’s role in the development of India as a major super-power would essentially be pivotal with VAYAM providing the basic structure & support for providing global standards in workforce training & schooling, without which the entire quality corporate structure would collapse.

Providing back-end support to the growing industries & providing the much needed human infrastructure support, we would aid the country in developing, quality human resource.
To ensure this, VAYAM starts from ground, up, developing the potentials of kids who would be the future. The basic idea being to develop India as a hub for world class talent in every field which would boost the nation’s economy as well as sustain a healthy per capita income, GNP/GDP level.

At VAYAM, we’ve laid a belief system that everyone in India, no matter the background, financials, language, religion, no barriers at all, shall discriminate a person’s talent & his ability to excel. That is the reason why at VAYAM we hold camps even for those who cannot pay, but have the will to excel.

We would try to raise the base level of the nation; the bottomline; the cut-off standards & set out new benchmarks for the forthcoming generations in terms of living standards, educational, mental, nutritional, co-curricular, etc. We wish to set across the same standards that exist globally for any other global citizen. It would be a new India.

Holographic Storage: The BIG Daddy of BluRay

 

The Holographic Versatile Disc (HVD) is an optical disc technology. It can hold many times the amount of information of a Blu-ray disc. It employs a technique known as collinear holography, whereby two green laser beams are collimated in a single beam. The green laser reads data encoded as laser interference fringes from a holographic layer near the top of the disc. A red laser is used as the reference beam to read servoinformation from a regular CD-style aluminum layer near the bottom. Servoinformation is used to monitor the position of the read head over the disc, similar to the head, track, and sector information on a conventional hard disk drive. On a CD or DVD this servoinformation is interspersed amongst the data.
A dichroic mirror layer between the holographic data and the servo data reflects the green laser while letting the red laser pass through. This prevents interference from refraction of the green laser off the servo data pits and is an advance over past holographic storage media, which either experienced too much interference, or lacked the servo data entirely, making them incompatible with current CD and DVD drive technology. These discs have the capacity to hold up to 6 terabytes (TB) of information. The HVD also has a transfer rate of 1 Gbit/s (125 MB/s). Sony, Philips, TDK, Panasonic and Optware all plan to release 1 TB capacity discs in 2019 while Maxell plans one for early 2020 with a capacity of 500 GB and transfer rate of 20 MB/s—although HVD standards were approved and published on June 28, 2007, no company has released an HVD as of May of 2010.

TECHNOLOGY

Current optical storage saves one bit per pulse, and the HVD alliance hopes to improve this efficiency with capabilities of around 60,000 bits per pulse in an inverted, truncated cone shape that has a 200 micron diameter at the bottom and a 500 micron diameter at the top. High densities are possible by moving these closer on the tracks: 100 GB at 18 microns separation, 200 GB at 13 micrometers, 500 GB at 8 micrometers and a demonstrated maximum of 5 TB for 3 microns separation on a 10 cm disc.
The system uses a green laser, with an output power of 1 watt which is quite high power for a consumer device laser. So a major challenge of the project for widespread consumer markets is to either improve the sensitivity of the polymer used, or develop and commoditize a laser capable of higher power output and suitable for a consumer unit.

COMPETING TECHNOLOGIES

HVD is not the only technology in high-capacity, optical storage media. InPhase Technologies was developing a rival holographic format called Tapestry Media, which they claim will eventually store 1.6 TB with a data transfer rate of 120 MB/s, and several companies are developing TB-level discs based on 3D optical data storage technology. Such large optical storage capacities compete favorably with the Blu-ray Disc format. However, holographic drives are projected to initially cost around US$15,000, and a single disc around US$120–180, although prices are expected to fall steadily. The market for this format is not initially the common consumer, but enterprises with very large storage needs.

Robotic Cars: The Future of Automotive Technology

In 2003, Sebastian Thrun was just a Stanford professor with a really cool idea. Having already built several prototype cars that feature autonomous driving, including one for a Smithsonian exhibit, the car enthusiast decided to go full bore with a new project that would eventually become Stanley, a robotic car built around a VW Touareg that won the DARPA Challenge in 2005 and has sensors that monitor traffic, control steering, and can self-park. (In 2007, Thrun returned with another VW model that took second place in the DARPA Challenge.)
With this success, you might wonder: what can possibly top a car that drives itself? Since 2007, Thrun has taken a sabbatical to help Google develop the Street View feature in Google Maps, which display photographic overlays to help travelers find hotspots. This year, Stanford is working on a new project involving a modified Audi TT-S that provides autonomous vehicle operation as well. But in many ways, despite the recent excitement surrounding new in-car technology by Ford and others, the days of DARPA are rapidly fading, and it almost seems like the idea of the fully robotic auto has lost momentum. Or has it?
In many ways, the dream of autonomous cars did not die at the last DARPA event. Instead, it was born anew. Several leading car companies have invested in robotic automation features and are now well on their way to providing an experience not unlike Thrun’s vision for autonomous control, where a driver simply presses a button and sits back in his seat while the car drives him home.

The Infinity EX 35: A Vision of the Future
Infiniti EX35 is a sports-sedan that drives exceptionally well. But it is advanced technology that sets it apart. The car has sensors all around it, and cameras in the in the rear-view mirrors and behind the vehicle that scan for obstructions. In some ways, the EX is more advanced than the Mercedes E-350 in that it shows how robotic automation could work: by scanning all around the vehicle. In tests, the EX would beep slightly when we approached to closely to a passing or stationary vehicle. The rear-mounted camera is also higher-resolution and more accurate than the Taurus Sho for backing up in a tight parking spot.
The EX also has exceptional lane-assist features – no wonder, since Infiniti was one of the first to invent this idea. In many conditions – including night driving, heavy traffic, partially obscured roads, and on city streets – the EX sensed the side of the road by scanning for white marker lines using front-mounted sensors. (Truth be told: we were pulled over by Las Vegas police while testing this feature and had a good laugh about it with the officer, who thought we were drunk-driving.)
Lane-assist uses a camera that scans for stark contrasts in the road and flashes an icon when you depart a lane. However, the car is smart enough to know the difference between a lane change and an inadvertent nudge – the EX waits a half-second before flashing the icon to sense a real lane departure.

 

Zero Accountability

I, as a visionary & an entrepreneur & as a guy who loves making people smile through his efforts, is actually feeling dejected the way things have gone in the recent past.

Why can’t people be accountable, sincere, honest?? They get paid for it and they don’t wish to work. Man, atleast have a look at what are you working for & what is on stake if you don’t work??

There can be nothing which can substitute your responsibilities towards the society & the nation. If a company is working for a much greater cause, than money, why can’t people understand it. You are getting paid for the job, atleast do your work properly man. The country’s future depends on the way you work. People leave their hopes in your hands so that you don’t let them down & is money, all that matters to you, that too without doing any work? Where is the sincerity & loyalty that everyone talks of?

No one, now-a-days, feels accountable for anything that has been entrusted to him/her. We have become comfortable with a system which has ZERO accountability. Is that the legacy we wish to pass on to our future generations?? Where is all the passion for a non-corrupt, responsible system?? Is this cheating & deceit what’s gonna give your kids their dream world?? Is this what you’ll pass on??

I mean how can you say that you didnt do you job properly coz u didnt “feel” like it??What do you say to the doctor who almost killed you child, coz he didnt feel like it?? You tell him that its okay?? Jobs, hopes, dreams & duties are not to be mishandled…

Wake up people. Darwin said it… either you fight or you’ll become extinct…. Time would move & the next generation, if bred properly, would wipe you off & would defy the very beliefs which have formed your world..

“Can we see mobile??”: An Insight into the Future of Mobile Communication

You have five senses: sight, hearing, touch, taste, and smell. While your mobile doesn’t have the last two (yet), it can have a few more: location (gps), proximity (to your ear), acceleration (speed), orientation (direction), and some even have temperature.

In what was one of the most interesting SXSW panels thus far, the experts at “What if your phone had 5 senses” discussed where our mobiles are heading. Below are a few of their ideas. But first, a trivia question: What was the first consumer augmented reality device? Answer after the break…
According to the panel: The Sony Walkman. You could walk around in reality listening to your favorite music. Though according to Nokia’s Jan Chipchase, the first augmented reality device was that transparent red paper that would show answers when overlayed on a test or board game. (remember that stuff? I do.) But on to the predictions…
– Navigating GPS on your mobile while driving can be unsafe. Using voice control would be much safer. But do you want everyone in the car able to accidentally give it voice commands? What if it used its’ proximity sensor to know when it was next to your ear? What if it was able to learn synonyms of words so you could say, “Take me to my homeboy’s pad, baby!” instead of “Navigate to John Smith’s house, baby!”
– Imagine your device was connected to you while you sleep and knew whether you were almost awake, dreaming, or deep sleep. What if instead of setting your alarm for “7:00″, you set it for “almost awake” so you don’t get awoken during that cool flying dream. (my second favorite dream)
If augmented reality is the future, wouldn’t mobile technology in glasses make sense? One of the SXSW panelists said, “Eyewear is the next mobile form factor”. Instead of keeping your head down to look at a device, it will always be up. Instead of a small screen, you’ll have the highest resolution possible. Instead of a photograph of your environment, you’ll see an overlay of metadata. And no more worries about the sun glare on your screen.
How about designer augmented-reality-glasses co-produced by trendy sunglass brands like D&G and Gucci? And how about a virtual pet dog that can only be seen through these glasses? Woof!
Or what if your mobile kept track of what you’re doing. What if it reminded you to stop visiting the liquor store. Or maybe it could recognize changes in your voice and could recommend a trip to the doctor’s office. I’d personally find this very useful.
Whatever happens or doesn’t happen, one thing is for sure: The future just keeps getting more awesome.

The Future of High Speed Rail Transportation: Automotrice Grande Vitesse (AGV)

Heralding the future of high-speed railway transportation, Alstom comes up with yet another massive breakthrough, after their PENDOLINO range of high speed trains, that are for operations at 200 to 270 km per hour on existing lines. Most of their PENDOLINO trains are equipped with a tilting mechanism that allows them to tilt in curves without slowing, and thus optimizing their running times without any need to upgrade existing infrastructure. This mechanism is based on their patented Alstom’s TILTRONIX technology.

With a growth rate of 3.6% per year for the next ten years, the very high speed market, currently worth an annual 2 billion euros, looks set to be one of the most promising sectors in the railway market.

In order to guarantee an economical solution, capable of ensuring the levels of performance, comfort and security already attained on high capacity trains, Alstom has chosen an entirely articulated and modular electrical multiple unit. This concept makes it prossible to propose a whole range of trains, developed on the basis of modules of several types of trailers whose motive power is not concentrated but spread all along the train. This architecture increases trains’ transport capacity and enables a global diminution of operating and maintenance costs.

The AGV™ is the first very high-speed train project to be developed following the publication of the European TSI (Technical Specifications for Interoperability) standards. The AGV™, capable of operating on all the networks in Western Europe from the outset, is also the product of the experience acquired by Alstom in the domain of high-speed trains outside Europe.

In June 2002, on-line trials of a demonstrator at 320kph made it possible to approve the guiding principles of the AGV™ project, whose design has been entirely developed by Alstom teams. The results obtained make it possible to envisage a further increase in the speed of trains on the European network, aiming at 350 kph while continuing to satisfy economic criteria.

About 100 engineers and technicians from Alstom have devoted themselves to the development of this business project, with contributions from a total of nearly 500 members of staff. The first certification tests have been run at the beginning of 2008. Alongside the La Rochelle integration site, centre of excellence for high-speed trains, three of the company’s factories are already preparing to build the AGV™: the Le Creusot factory for the bogies, the Ornans factory for the engines and the factory in Tarbes for the traction system.

The Challenge
Air transport currently presents travellers with numerous problems, from extended check-in times to overcrowded airports. The challenge for very high speed rail travel is to offer a commercial service speed of 360 km/h, passing the threshold of 1,000 km in three hours to further increase the appeal of train travel over other modes of transport.

Pressure on energy costs have also led rail operators to demand exceptional cost performance. The ratio between train capacity and energy consumption has, as a result, become a decisive market factor.

Alstom has developed a new generation of very high speed trains, AGV (Automotrice Grande Vitesse), to meet these new requirements.
The concept
Designed to travel at 360 km/h, the AGV is the first train in the world to combine articulated architecture with distributed power. The principle of the articulated train set is based on a design that places bogies between the cars. This technique, which has ensured Alstom’s success for 25 years, eliminates much of the vibration and rolling noise on board, cushions movement between cars, optimizes aerodynamic performance, guarantees maximum security, and reduces maintenance costs by 30%. The distributed power principle spread along the train increases on-board capacity by 20%.

The combination of articulated architecture, composite materials, and improved traction systems have made it possible to reduce the mass of the AGV by 70 tonnes compared to competitors’ trains. The AGV is therefore particularly efficient from an environmental point of view, consuming 15% less energy.

Distributed power also offers the advantage of modularity in relation to car numbers. Based on an AGV range comprising between 7 and 14 cars, each operator can built up a fleet to match their capacity requirements.

Key figures
Modular design: 7 to 14 cars (130 to 250 m)
Seats: 250 to 650
Mass: 270 to 510 tonnes
Power: 6,000 to 12,000 kW (22 kW/t)
Traction equipment : Quadri-voltage 25 kV 50 Hz / 15 kV 16.7 Hz / 3 kVdc / 1.5 kVdc, water-cooled IGBT traction converters, permanent magnet motors

For the reference:
Alstom occupies first place among manufacturers and has built 70% of the trains in service in the world which travel at more than 300 km/h. The company’s very high speed activity is constantly growing. It will account for 6% of sales during 2006-2007 and is expected to reach 10% in 2010, thanks to Alstom’s unrivalled experience and technological lead.

Guide & Mentor

Being a guide, a mentor, a teacher is a tough job.

More than usual, I find myself in this extraordinary situation, where every word has to be carefully weighed, should have gone through the acid tests of reasoning & should be logically & ethically sound. My world revolves around structuring lives that would influence the very basis of thought which creates the foundation of human excellence.
My students are the same people who would shape India into what it would be tomorrow & they are the future that lies in wake of the turmoils of the present. Giving them the right direction, showing them the path towards an ethical, successful & honourable life.
Teaching them ways of words like honour, commitment, prestige, ethics, etc. which seem to have been lost in the struggle for survival in the contemporary world, is an extremely difficult path to tread because the world that they’ve noticed, born & brought up in, denies the existence of these words and thus, making my task, extremely failure prone.
My students make me proud by following the leads given to them on several occasions. Parents, sometimes, can never understand how just one sentence can alter the child’s life, but VAYAM’s efforts towards an honourable world, a world that acknowledges a man for what he/she is, not just for what he/she has, is what I, Sanand Mitra, offer as a humble offering to humankind, dedicated to the undiminishable spirit of human strive for excellence.
