What a busy few months, and it's just getting busier!
This week I have been designing a pre-amplifier for our seismometers, trying to make one that is quiet enough to help boost the signal without boosting the noise. I'm trying to work with signals as low as a few microvolts however; so all it takes is a few microvolts of noise and the signal gets lost... A * (noise+signal) = A*noise + A*signal. The non-technical way of saying this is what happens to a good voice recording when there's a computer fan running in the background. No matter how high you gain up the voice, the fan will still be there , just as loud as the voice. I'm working on it!
- Some good news is that our research was well received in Vienna at the U.N. CTBTO SnT2015 conference, which is an international conference on science and technology that supports efforts to ban nuclear weapons tests all over the world. It was a good week. We got a lot of pictures in the evenings after the conference, and my wife even got to come along with me. Now the hard part - Tallying all my receipts and getting the travel reimbursement vouchers all turned in. That's pretty important, because this wasn't a cheap trip... Especially for a grad student.
- Tycho Aussie is back, after being sent in for some 'tuneup' work at Beastcub Creations. The fursuit is safe and sound, all brushed and ready for the Anthrocon in Pittsbugh, PA which I will be attending next week.
Only one week to go !
After that, it's all research & developmetn as well as writing on the thesis. Speaking of which, I need to get some lunch and get back to the other screen where my abstract is staring at me...
