The chirp of the cricket may soon be used to monitor their species diversity.
Scientists are establishing an acoustic signal library that can help track the diversity of these insects.
Morphology-based traditional taxonomy has gone a long way to recognise and establish species diversity. But it is often not sufficient in delimiting cryptic species– a group of two or more morphologically indistinguishable species (hidden under one species) or individuals of the same species expressing diverse morphological features (which are often classified into multiple species). Therefore, identification solely based on morphological features leads to underestimation or overestimation of species diversity.
As per reports, after a discussion between National Security Advisor of India and Foreign Minister of China, yesterday night, Chinese troops have started to withdraw from at least three places. Withdrawal from Penang Tso is not yet clear. But this is not over. The war had started long ago and it is not going to end with this small retreat. The war between China and India is always on and will always be on till there is a Communist Party in either of these countries. Do not belive me? Read this headline in newspaper:
In 1962 Chinese troop had done the same thing before attacking the area behind it which was then called Aksai Chin and now we call it Aksai Hind. So retreat means almost nothing.
Indian Airforce had earlier started its war exercise in Ladakh.
The exercise which started yesterday has many purposes. Apart from practice the terrain it also exercise possible moves and resultant reactions from enemy. This is getting serious. Watch this:
Let’s revert back to the topic in hand about the Missile choices for India. India has so far deployed Astra and Nirbhaya Missiles. But there is another name. Brahmos, which is now India’s bread and butter missile. It is also unstoppable missile in the world.
Astra Missile
Astra is an all weather beyond-visual-range air-to-air missile developed by the Defence Research and Development Organisation. It is the first air-to-air missile developed by India. It features mid-course inertial guidance with terminal active radar homing. Astra is designed to be capable of engaging targets at varying range and altitudes allowing for engagement of both short-range targets at a distance of 10 km and long-range targets up to a distance of 110–160 km
It means an Indian Fighter plane at the LAC can fire a missile and hit a target 160 Km inside the territory in the control of China.
Nirbhaya Missile
The missile is guided by a highly-advanced inertial navigation system which is also indigenously designed and developed by the Research Centre Imarat (RCI), DRDO sources had told PTI. ‘Nirbhay’ missile can travel with a turbofan or turbojet engine. The way it functions is this: Soon after the cruise missile is able to achieve its designated altitude and velocity, the booster motor is separated and the engine automatically switches on taking further propulsion.
Akash Missile
Akash is a medium-range mobile surface-to-air missile (SAM) defense system developed by the Defence Research and Development Organisation and produced by Bharat Dynamics Limited for Missile Systems, Bharat Electronics, Tata Power Strategic Engineering Division and Larsen & Toubro for other radars, control centers, launcher systems in India. The missile system can target aircraft up to 30 km away, at altitudes up to 18,000 m. The Akash system is fully mobile and capable of protecting a moving convoy of vehicles. The launch platform has been integrated with both wheeled and tracked vehicles. While the Akash system has primarily been designed as an air defence SAM, it also has been tested in a missile defense role. The system provides air defence missile coverage for an area of 2,000 km2.
Now compare this with the missiles of China. China may have assault missile of long range but the same can be detected and shot down easily with the Askash Missile or other missiles. But Akash as SAM air defence is far more superior in technology and speed over the missiles of China. Similarly all these missiles are sleek and portable, unlike China which has to use huge trucks to fire and operate the missiles. And I have not yet talked about Brahmos in this article at all. There is a squadron of Sukhoi planes fitted with Brahmos missiles now waiting at Ambala Airbase for Orders.
Actually the position of technology is same with China. No country has given it any latest technology in any military field and technology of China has not progressed beyond reverse engineering. The fighter planes too have similar problems for China. See this video is about the fighter planes which both countries are not going to use as these are not for dog fight but mere air superiority:
Comparison of J-17 with Tejas
India has large squadron of Sukhoi SU 30 MKI which is made in India with Russian technology and Mig 29 which is a Russian plane. China rely of J-20 which it calls fifth generation plane with stealth but India air force asserts that it can detect J-20 without any difficulty and thus making the claim of stealth doubtful.
The China may have large inventory of everything it has, but number do not always matter. Especially with an enemy who is as large as India and has indigenous production of weapons it is relying and a short supply line due to geography.
But that is not the point. China knows it too well. Why then it keeps targeting the borders of Ladakh or Arunanchal Pradesh or Bhutan? There is a big strategy involved in this. Until India will call China’s bluff it will keep troubling India in the North. India is maintaining 90000 strong Mountain Force. It is the largest mountain ready army in the world. Such Large force entail huge expenditure. The real soft belly for China is in Indian Ocean. Unless India starts to caress this soft belly, China will keep troubling it in the North to keep India burn resources in North.
Remember Hollywood TV Show called ” Person of Interest”?
Soon it would not be entirely fictional. India is going ahead it’s long pendinding plan to form a National Intelligence Grid.
Union Home Minister Amit Shah is going to hold a high-level meeting on Friday to launch the National Intelligence Grid (NATGRID).
India is facing Jihad since it’s inception i.e. 1000 years and it fell before Temurite dynasty because of its failure to have proper intelligence. India was prepared for a war of supremacy but what arrived was a death match. The genocide and destruction that followed has parallel only in ISIS and it’s deeds.
9/11 in USA is another example of gross failure of Intelligence. Last 6 years in Indi have been remarkable as terrorists have been caught in preprations but no civilians have been attacked.
Reverting back to NatGrid, it will start working by the end of the year.
Chandrayan 2 was launched yesterday and it uses the same technology of gravitational pull that was used by Mars mission spcecraft, Mangalyan. The reported mission is stated by ISRO as under:
July 22, 2019 at 14:43 hrs IST from Satish Dhawan Space Center at Sriharikota on-board GSLV Mk-III. It will be injected into an earth parking 170 x 39120 km orbit. A series of maneuvers will be carried out to raise its orbit and put Chandrayaan-2 on Lunar Transfer Trajectory. On entering Moon’s sphere of influence, on-board thrusters will slow down the spacecraft for Lunar Capture. The Orbit of Chandrayaan-2 around the moon will be circularized to 100×100 km orbit through a series of orbital maneuvers. On the day of landing, the lander will separate from the Orbiter and then perform a series of complex maneuvers comprising of rough braking and fine braking. Imaging of the landing site region prior to landing will be done for finding safe and hazard-free zones. The lander-Vikram will finally land near South Pole of the moon on Sep 7, 2019. Subsequently, Rover will roll out and carry out experiments on Lunar surface for a period of 1 Lunar day which is equal to 14 Earth days. Orbiter will continue its mission for a duration of one year.
To understand the technique of using gravitational pull, this picture uploaded by ISRO explains better:
Human programming is a fact for me but I do not think that everybody in the world is ready to accept it. More so, a large majority of people may not even understand it. To understand the meaning of a word it is interesting to how different languages express it. But before that, lets understand what programming means in respect of computer program. Interestingly when Woogle translated it in Hindi it came out as “कार्यक्रम निर्माण” which if re-translated in English would be expressed as “creation of work/program”. Interesting?
Computer programming
The world programming is actually used in respect of computers. A program when in operation is also referred as “Algo Rythm”. The process of writing a computer program is called coding as it entails writing a long lines of codes in computer programming language. BTW the most popular language is called “C” and it’s latest version is called as “C++”. For example the first program which is taught to a beginner is how to make computer to give output of “Hello World” on screen. An example of the code: Continue reading →
