The Measurement of Polarization in Radio Astronomy
[article]
2018
arXiv
pre-print
Modern dual-polarization receivers allow a radio telescope to characterize the full polarization state of incoming insterstellar radio waves. ...
We go to lengths to dissuade the reader of this concept: the backend is the least complicated component of the radio telescope when it comes to measuring polarization. ...
This work made extensive use of NASA's Astrophysics Data System Abstract Service and IEEE Xplore Digital Library. ...

A novel non-acoustic voiced speech sensor
2004
Measurement science and technology
On a non-academic level, he also made the decision to join the Lambda Chi Alpha Fraternity, a highly unlikely decision by one who entered college as a selfproclaimed GDI, but which turned out to be one ...
One promising technique currently being utilized in speech-coding applications is a multi-sensor approach, in which a microphone is used in conjunction with optical, mechanical, and electrical non-acoustic ...
The drawback to this method is that the speech signal used to calculate the SNR is only an estimate, and as such the accuracy of the SNR measurement is limited by the accuracy of the speech estimate. ...

Physics and Fiction
[chapter]

Physics and Literature
The mythical character of a theory does not diminish its scientific validity; quite the contrary. Convincing myths are not easily found and better observations demand better myths. ...
It is not within its power to explain reality, but it can fictionalize it and thus make it understandable, sometimes even predictable. ...
Indeed, the level of theoretical knowledge and computational power required to achieve such a goal is stupendous: anyone who had such a power would probably find the whole framework of density functional ...
