... In order to get actual measurements of the fluctuating network flow rates between some astronomical Web sites, the CDS has developed a tool called AstroRoute. ... AstroRoute is a system to get measurements about the connectivity and the quality of the network between astronomical web sites. ... There exists a lot of network tools to test network quality, but the main problem is that the tests are generally done from one single site--the tester's own host machine. ...

... Remote Sensing of Fire Intensity and Burn Severity in Forests of Central Siberia . ... Increasingly sophisticated and comprehensive estimates of burned areas and of active fire areas are being produced using satellite imagery. However, accurate regional estimates of fire intensity, ecosystem fire effects, and fire emissions to the atmosphere require development of accurate remote-sensing based methods for estimating the intensity of active fires and the severity of fire impacts. ...

... Low-Frequency Flux-Density Measurements and Spectral Features of Millisecond Pulsars . ... Radio flux-density measurements for a large sample of millisecond pulsars at a low frequency of 102 MHz are presented. ... The spectra of millisecond and normal pulsars have been found to differ. The spectra of millisecond pulsars have no low-frequency turnover typical of normal pulsars. ...

... DIAGNOSTICS OF IONOSPHERIC IRREGULARITY SPECTRUM USING MEASUREMENTS OF RADIO WAVE ANOMALOUS ATTENUATION UNDER VERTICAL SOUNDING . ... The selected experimental data are characterized by a high average level of attenuation of a signal of vertical sounding (10 dB and above), which cannot be caused by collisional absorption of radio waves (practically absent in a dark time of day) and, hence, being a consequence of scattering on random irregularities. ...

SLIDE 1 Coherent beam­beam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchro­betatron modes in the beam­beam system, and thus a head­tail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchro­betatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
