March/24/2017 is a historical day for India After England, USA, France and Israel; India is a fifth county which develops his own navigation system for ships.  Secondly, after the democracy India first time export defence items. India gives three SONAR system USHUS-2 to Myanmar and the cost of this product is about 180 crore. USHUS-2  is developed by Naval Physical and Oceanographic Laboratory (NPOL), the only Defence Research and Research organisation (DRDO) lab in Kerala, India. Union Defence and Finance minister  Mr Arun Jaitley handed over  10 USHUS-2 to Indian navy too.   USHUS-2 USHUS-2 is an integrated submarine sonar suite, a state-of-the-art upgraded of existing USHUS sonar presently operational on the frontline submarine of Navy. USHUS will replace Russian sonar system. It is designed and manufactured by DRDO. The range of USHUS-2 is about 100 to 150 kms. 

Graphene is an allotrope of carbon in the form of a two-dimensional, atomic-scale, hexagonal lattices in which one atom from each vertex. Graphene can be described as a one-atom thick layer of graphite. It is the strongest, thinnest material known to exist. Each carbon atom is sp 2 hybridized and it is bound to its the neighbors. History of Graphene One of the very first patents pertaining to the production of graphene was filed in October 2002 entitled, “ Nano-scaled Graphene Plates”. Two years later, in 2004 Andre Geim and Kostya Novoselov at the university of Manchester extracted single-atom-thick crystallites from bulk graphite. Geim and Novoselov received several awards for their pioneering research on graphene, notably the 2010 Nobel prize in physics. Structure of Graphene Graphene is a 2-dimensional network of the carbon atom. These carbon atoms are bound to the plane by strong bond by strong bonds into a honeycomb array comprised of six-memb...

As mine previous blog we know about Hyperloop what it is?  Link: http://yourtechnomate.blogspot.com/2017/02/hyperloop.html And now we going to know about the technologies on which hyperloop works. Hyperloop have high speed due to some technologies combine together we know then one by one     Just like magneto trains, Hyperloop has magnets ay the bottom of the capsule which but the capsule in the air which provide low friction i.e. approximately zero due to low pressure in the Hyperloop tube.  In Hyperloop system the capsule contains air compressors which provide thrust to the capsule.  The vactrain concept theoretically eliminates these obstacles by employing magnetically levitating trains in evacuated (airless) or partly evacuated tubes, allowing for speeds of thousands of miles per hour. However, the high cost of maglev and the difficulty of maintaining a vacuum over large distances has prevented this type of system from ever being buil...

For transportation, we use a bus, train, ship, airplane and spacecraft’s and these are not nature-friendly. But here the latest technology is coming now that is Hyperloop whose average speed is 900 km/hours and completely nature-friendly. It has a steel tube which has a capsule-like structure which carries passengers and luggage and this capsule travel from one place to another place with high speed due to negligible friction. Negligible friction is achieved by the low pressure inside the loop and capsule float in the air by installing the magnet on the bottom of our pod (i.e bottom of the capsule). The capsule contains a battery with providing power to an air compressor which provides thrust to the capsule. It consumes very low power and this power is obtained from the solar plates place over it. The overall system is power generative because it produces more energy than it consumes. It is completely environment-friendly because there is no noise pollution, work o...

The owner of the internet? Do you know this? No?? Let’s know this! We daily use the internet and pay money to our service providers. Are they are the main owner of the internet? The answer is no. The owners of the internet are the companies who setups the cables in oceans.  And they not completely own the internet. In short, we pay to our internet service provider, they take their interest from us and they are payable to the companies who setups the cables in oceans. That’s the process and that companies are not payable to anyone only they pay the taxes if any. The main point is that no government can lay claim to owning the internet. The internet works because of a system of rule called protocols. By following these protocols, computers can send information across the network to other computers. If there were no protocols, then there be no guarantee that the information sent from one computer could be understood by another, or that it even reache...
