Re: Wuhan Coronavirus Resource Thread

We are at war with the virus and we need to build herd immunity without a vaccine. What if a country attempts to create people immune to the virus in the following controlled fashion. Younger people are relatively unharmed, lets assume that 1% of infected young people need to be hospitalized and req...

Re: Understanding the US - Again

There is behind the scene push for ABA to change its rating of Kavanaugh WSJ edit pushes back with: Mr. Kavanaugh didn’t ignore his 307 judicial opinions and hunt for dirt to destroy his reputation. Mr. Kavanaugh didn’t float charges about gang rape and ask questions about adolescent entries in a hi...

Re: Understanding the US - Again

The following line's in wsj's editorial caught my eye https://www.wsj.com/articles/confirm-brett-kavanaugh-1538089143 Had he not been as forceful, his opponents would have said he looked guilty. Because he called the Democrats out for their character assassination, the critics now say he lacks the r...

Re: Malaysian Airlines Flight MH-370 goes missing

That 1 ppm is long term drift. What is the stability of the VCO at the 10 ns level? I can correct the long term drift by periodically checking with a reference clock like the NIST signal. I can't fix the short term drift. Unless the short term drift is ~ 1Hz on a 1.5GHz carrier, I would not be comf...

Re: Malaysian Airlines Flight MH-370 goes missing

I have worked on Sat modems before, including those that talk to Inmarsat satellites. The modem on the airplane will receive the signal from the satellite and use it to remove its own oscillator drift, just like your cell phone does right now. Only thing left is doppler due to speed. No magic here,...

Re: Malaysian Airlines Flight MH-370 goes missing

These conspiracy theories don't add up. Agree I don't know how much to trust the Doppler shift data as I don't know what the stability of the oscillator on the plane is. The plane does not passively reflect the ping, it actively re-transmits it. That puts the entire shift analysis in question. I ha...

Re: Malaysian Airlines Flight MH-370 goes missing

One possible explanation.....on the doppler theory. Anyone kind enough to translate in layman terms to non-engg folks? http://www.pprune.org/rumours-news/535538-malaysian-airlines-mh370-contact-lost-400.html#post8399298 Let me give it a try: * Doppler is the fancy name given to frequency translatio...

Re: Pokhran II not fully successful: Scientist - Part-2

While KS latest interview has been reported here many times, I found the following transcription in economic times odd. http://economictimes.indiatimes.com/Politics/Nation/India-lacks-deterrence-Santhanam/articleshow/5040401.cms According to Mr Santhanam, the hydrogen bomb test, which was the second...

Re: MRCA News and Discussion

India's MRCA is pretty much the same. $10 billion is a big money but its a mere pittance required to convince anybody to stop applying FULL sanctions on India for resuming nuclear testing. I agree. For example, here is what Boeing has 'pre-ordered' for its dreamliner: http://www.nytimes.com/2009/09...

Re: Internal Security Watch

A lot of time has passed - doesn't the helicopter have a black box? Does one have to fly right over the black box to detect it, I wonder. One of the TV channels had some one from the army as an expert. He said that this helicopter does not have any form of a beacon emitter. Apparently only army hel...
