... A bolometer consists of a thermometer with heat capacity C mounted on an absorbing substrate, weakly coupled to a bath at temperature T 0 via a thermal conductance G ( Figure 1 ). ... We have developed a new bolometer concept using a non-dissipative thermometer coupled with a heat switch to break the link between thermal conductance and performance. ... Temperature changes in the bolometer thus depend solely on the integrated infrared power incident on the absorber. ...

... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

. You can compare any two versions of a file that is under the control of SCCS with the sccsdiff command: /usr/sccs/sccsdiff -r version -r version s. filename . Using this command produces a line by line difference between the two versions of the file. Results are shown in the same format as that produced by the diff command. Examples .

Jeff mock supplied 6 different types of filters to use with the high resolution mode of the mock spectrometer. ... Plots were made of the time domain voltage response as well as the frequency domain power response. A decimation of 10 was used for the filter decimation. this gave a filter length of 80 coeff.

The theory predicts that the oscillation period should be proportional to the square root of the oscillating mass, including the mass of the clip. Note that gravity plays no part here: the oscillation period would be the same on the Moon or in zero-g. Denoting square root by SQRT, we have . ...

... We have made series of computer runs of the orbital evolution of asteroids for the 3/1 and 5/2 resonances with Jupiter using both the symplectic integrator RMVS3 [1] and the Bulirsh­Stoer method [2] (BULSTO). ... Besides the values of r hc presented in the Table at N = 144, for the 3/1 resonance at N = 24 we obtained r hc equal to 4.0, 1.7, 0.33, 0.4, and 0.7 at '' = 10 \Gamma8 , 10 \Gamma9 , d s = 3, 10, and 30 days, respectively. So in some cases a symplectic method can give large errors. ...

... In short, ROMAFOT performs the best fit by comparing a given pixel to the value of the PSF at the centre of the pixel. This approximation is valid if the pixel size is small compared with the scale length of the point images. ... With the commands below the integral of the PSF over the pixel area is computed via the Gauss - Legendre integration formulae which are characterized by a high precision for a correspondingly small number of subpixels where the PSF must be calculated. ...
