... also take data with dewar monitoring turned off. a2010 alfalfa data from the last year was used to get an idea when the problem started. ... You can see the oscillations clearly in beam2a,b . ... The oscillation does not show much frequency dependence. 16feb11: . ... A 2.5 MHz oscillation was seen at the dewar bias voltages when a spectrum analyzer was attached at the dewar. 21jan11 (.ps) ( .pdf) . ... Turning the dewar bias monitoring off caused the oscillation to disappear. ...

... Data from various satellite missions concerning emission lines formed at temperatures of 7 x 10 4 K to 1.3 x 10 5 K show oscillations in sunspots with frequencies in the range of 5.8-7.8mHz. ... All the observational data clearly indicate the presence of 3-minute oscillations in sunspots in spectral lines covering a vast temperature range from the low chromosphere to those lines normally associated with coronal temperatures. ...

Next: Inverse transform Up: No Title Previous: Analysis of a . As pointed out earlier, if the data are periodic, Fourier analysis is best and there is no need for wavelet transforms. ... First, we show the graph of with its Mexican-hat wavelet transform (Fig 12). Figure 12: g2-wavelet map of showing the gradual shift to shorter durations. ... Figure 13: g2-wavelet map of a strongly modulated oscillation. ... Figure 14: g2-wavelet map of an intermittent signal. ...

... Toward this goal, the Baryon Oscillation Spectroscopic Survey (BOSS) of the Sloan Digital Sky Survey -III (SDSS-III) has measured slight recurring density enhancements in galaxy densities up to six billion light years away ( redshift 0.7), when the universe was about half its current age. ... BOSS's measurements of this size scale indicate a strong universe component of dark energy , and so bolsters previous indications of this unusual composition. ... NASA Official: Jay Norris. ...
