... A three-cell test section roughly representative of the primary mirror was provided for this test by the Steward Mirror Lab. ... Additionally, the tests are intended to determine relative airflow vs. pressure drop characteristics for each of the air flow patterns so the results can be evaluated both as a function of flow rate and of pressure drop along the flow path. ... The bottom (top as installed) was cut out so it could close the chamber for heating and be removed for the cooling tests. ...

... Under certain conditions, like those in the nucleus of a QSO, all atoms can be made to emit light at particular wavelengths. ... If that source is approaching the observer, the wave is squashed up onto itself making the wavelength shorter. ... This is redshift. ... You can see how the section of the QSO spectrum which we observe changes with redshift. ... We then see how far we had to slide the observed spectrum along the scale to make it match and that is the objects redshift. ... The 2QZ team . ...

The HyperNews Linux KHG Discussion Pages . ... Keywords: scheduler overhead . ... From: Jasleen Kaur < jks@cs.utexas.edu > . Hi, I am implementing a different scheduling policy in the scheduler of Linux 2.0.0. I need to measure the time taken for choosing the next task to be scheduled, i.e., the actual time spent in the schedule() function, without the actual context switch having taken place. Since I clear interrupts in schedule(), how do I measure the time? ... Thanks, Jasleen Kaur . ...

... Astrophysics Group . ... COAST . Fringes and Power Spectra from COAST . ... After acquiring a star, measurements must be made of the (complex) fringe visibility on each baseline. ... Fortunately, even in the presence of very strong atmospheric turbulence there is a good observable: the phase of the triple product of the visibilities on three baselines, commonly known as the closure phase. ... We then form the power spectrum of the resultant data, and hence estimate the visibility. ...
