Very nice.

Are there any new features that ISRO has uncovered which can be given Indic names.

"it will be sent to space in late September along with six small “piggyback” satellites of three foreign customers." Nice! This is news, I had heard of Lapan satellite of Indonesia being a passenger, but not 5 other satellites. So another 7 satellite launch( the 3rd for PSLV) coming up, o...

the Govt is not helping. it must be made mandatory for all cellphones sold in India from mid 2016 to be capable of and receive IRNSS signals (apart from gps and glonass most claim) and Govt body like ISRO or BEL can release free reference API kits and apps to pull info from this feed. Absolutely. N...

can anyone point me to link or tell how do we get a sense of data rate measured over frequency. let us say 50mbps using 5GHz wireless tech.. what is the relationship between 50mbps and 5ghz? is there a table or something? 5GHz is the frequency of the carrier wave and it is usually got nothing to do...

The radio chipset must be physically capable of generating these frequencies along with an antenna tuned for it. The Nokia 920 has 1700/1900/2100 for HSPA+21 even though Nokia doesn't advertise it as such. The Nokia 808 does not have the right chipset for 1700 MHz downlink. It has yet to be announc...

It's not just EDGE. LTE is also a huge battery hog. It depends on how LTE is implemented. Long Term Evolution - LTE is industry jargon for the idea of using spread spectrum technology more efficiently. It is an open standard for CDMA and eventually all voice will be LTE as well. The problem is how ...

Dhanyawaadam SriniYjee. Is it worth to buy Thinkpad T530 just for bigger dimensions considering 15.6" screen is not common as 14" is? Also hearing that DVD Writer are to slowly getting obsolete with newer models coming in market without DVD W/R, will that trend catch up with thinkpad/vost...

Can some one explain in a bit more detail how a surface to air quick reaction interceptor with a directional warhead <100kg has been modified to a surface to surface missile with a huge payload and much extended range?

SriniY

At the resolution at which an IR sensor would see the chopper, my guess is you would find one smooth (but not so bright) image

What is the thing on the Rustom UAV in the second picture ?

SriniY

AFAIK, PA and PAF maintain a huge inventory of SAM's for this very purpose.

it might be also possible that 5000 is the total list of targets, and probably a good portion could be taken out with long range artillery.

SriniY

5000 targets. wow. Even if say 2000 targets are to be taken out in the first few days of battle, that calls for about 1000 - 1500 sorties just for strikes. And then strike packages need escorts and there would be aircraft set aside for air-to-air just in case. Wonder if IAF can do such an intense bo...

Singha sir,

Most massa universities are more interested in minting money from indian/chinese students and dont really care much whether you do a MS thesis or not and if you do its quality. My above post was in reference to graduate study in India

SriniY

There are two ways in which you could get a masters in India as far as I know. In the first, after your BS/BTech you could join a masters program typically for two years. The first one year would be course work in most cases. Students get to choose two options here. You could do some more course wor...
