#IJSRD Private Virtual Infrastructure (PVI) and Locator Bot

Also addressing the security and confidentiality issues surrounding cloud computing is University of Maryland, Baltimore County researcher John Krautheim. His proposal is aimed at better sharing the risk responsibility between the cloud provider and customer, giving the customer much more control than is typically the case. "A method of combining the requirements of the user and provider is to let the clients control the security posture of their applications and virtual machines while letting the service provider control the security of the fabric. This provides a symbiotic security stance that can be very powerful provided both parties hold up their end of the agreement,"

#IJSRD Astrophysics and Space Sciences

Physicists in the McDonnell Center for the Space Sciences use experimental techniques of high-energy physics, observational techniques of astrophysics, and the laboratory study of extraterrestrial materials to address a variety of astrophysical problems. These include the origin of cosmic rays, energetic processes in galactic and extra-galactic objects, the synthesis of heavy elements in nature, the formation of dust around stars, and the history of the lunar surface and of meteorites.

How Does Whatsapp Generate Revenue? #ijsrd

Whatsapp: The leading OTT messaging service. There is always a prominent question baffling every user’s mind – How is Whatsapp able to make money when its services are free of cost?

Whatsapp enables it’s user to send text messages, images, video and audio media to other whatsapp users. The said service is available on iOS, android, Symbian, blackberry OS and windows platforms.

On a different note, we know Facebook has recently bought Whatsapp. Do you want read about it? Read about it here! Just follow the link!

Okay, back to business now!

Whatsapp is earning its revenue through two different ways:

1) Subscription Fee: Whatsapp allows it’s user to enjoy Whatsapp services for free for first year. However, after that it charges $0.99 for continued service. But till date, I have not heard of a single person who has paid for this service. Interestingly, Whatsapp tend to extend the free service period every time a user reaches close to the expiry date.

So this method of revenue generation that seems like the only visible revenue generation scheme is actually not generating the revenue for Whatsapp.

2) According to my speculation, the revenue generation for Whatsapp is primarily through database management. All the conversations on Whatsapp are backed up on Whatsapp servers constantly. Our conversations reflect our interests, likes, dislikes and majorly depicts our preferences. This information is invaluable to big firms where relevant tailor made products can be offered after data sorting.

Let’s take a deeper look into this!

Whatsapp users have been ever increasing since launch currently numbering out users on any other competitor.

Given such high number of users, the number of messages exchanged per day is also incredibly high in case of Whatsapp- peaking as high as 11 billion. With such extensive information available on Whatsapp backups, the big companies are willing to pay handsome amounts for information extraction.

This data management scheme is merely a speculation. As evident, Whatsapp is not involved in ad marketing. Any Whatsapp user can vouch for the fact that Whatsapp does not support advertisements. Whatsapp’s CEO Jan Koum clearly states that Whatsapp is meant for instant messaging and forcing advertisements would disrupt the sole meaning of Whatsapp and instant messaging. There is no way to justify the data management ideology, but then there is no other justified revenue model as well in the store.

#IJSRD Technology That Allows Users to See Through Walls and Melt Objects

It would be interesting to note that the researchers have also been working on an invention that would make it possible for users to see and sense virtual objects. The new technology is called Visuo-Haptic Augmented Reality and it allows an individual to manipulate a 3D object by making use of a head mounted screen and touch-based gadgets.

#IJSRD new research in Sixth sens By Microsoft

RFID based enterprise intelligence

The vision of the SixthSense project in the MNS group at Microsoft Research India is the workplace or home of the future where computing is extended to encompass non-computing entities such as people, objects, and spaces to enable rich user experiences. For instance, we would like users to be able to search the physical world for objects they may have misplaced or use physical events to index their experiences (e.g., "was my laptop with me when I received a phone call from person X?").

# ijsrd – Intel releases rare details of its custom CPUs for Oracle – and there’s a lot more to come

We’ve known for quite some time that Intel was building special versions of certain cores for its large data center customers, but the chip giant has kept the details of the implementation secret — even when negotiating for contracts with companies like Google, Facebook, and Amazon.

Now, some details on Intel’s deal with Oracle have come to light, and they shed light on the kinds of optimizations the company is baking in. Specifically, Intel’s new Xeon E7-8895 V2 is identical to the Xeon E7-8890 V2 released last winter — but the new 15-core chip (pictured above) has received some validation cycles that the other Xeon hasn’t had.

The enhancements that Intel is discussing all relate to server version of Turbo Mode. When Intel sells a consumer chip — say, a Core i7-4960X — it verifies that the chip can run at certain increased frequencies with a given core count. Two cores might hit 4GHz, four cores top out at 3.9GHz, and all six cores could be limited to 3.7GHz at most.

What Intel has done with the new E7-8895 V2 is to validate the core at the clock speeds and frequencies that other components in the stack would normally target — and to allow it to switch to these alternate operating modes on the fly. Do you want an E7-8895 V2 (15 cores, 3.4GHz maximum clock) to reconfigure itself as an E7-8893 (6 cores, 3.7GHz maximum clock)? The new chip can do that without even requiring a reboot.

The new Xeon E7-8895 V2 can reconfigure itself to look like the 8891 or 8893 on the fly.

Intel has also released a taped interview with the data center group’s general manager, Diane Bryant, in which she states that this kind of collaboration is central to Intel’s long-term plans. “As our collaboration continues, we are actually co-defining — with the Oracle engineers [and] with the Intel engineers — next-generation instructions that will further accelerate the Oracle database solution, and those will be coming in future processor generations. Things such as memory enhancements, vector manipulation acceleration, and cluster interconnect performance acceleration.”

Intel also stated that the new Xeons can hit lower power targets than typical chips and possibly spin the cores up more quickly, but the company hasn’t released any information on this. The implication is that the company may actually be power gating the cores to nearly off, in order to use as much thermal headroom as possible to ramp up frequency on the other chips. Presumably there’s some additional validation associated with this — if Intel wants to hit higher Turbo frequencies with a given number of cores, it needs to know which CPU cores can hit those frequencies and which it should power gate.
