... We are developing the following problems: a) combine optical and microwave technic to the indication of non-linear surface waves and wave breaking field; b) modelling of microwave propagation in a multiphase air-water interface; c) obtain quantitative dependencies of microwave radiation on geometry and statistics of wave breaking field in ocean surface; d) monitoring of ocean surface states using optical amd microwave airspace data sets. ... Important issue is spray and underwater bubbles. ...

... Io's Surface: Under Construction . ... Io's surface is constantly under construction . This moon of Jupiter holds the distinction of being the Solar System's most volcanically active body -- its bizarre looking surface continuously formed and reformed by lava flows. Generated using 1996 data from NASA's Galileo spacecraft, this highest resolution composite image of Io is centered on the side of Io that always faces away from Jupiter. ... 1995 1996 . ...

Next: Particle Background Rejection Up: Detection Efficiency Previous: Front Illumination . ... The method requires that the CCD substrate be etched from the rear towards the depletion layer boundary. The device can be illuminated through this rear surface, which has a much thinner dead layer than the electrode side. ... The corresponding detection efficiency data are presented in Figure 7, and compared with the predicted data for a 20 m thick depletion layer. ...

... For SIMS (Secondary Ion Mass Spectrometry) analysis, a solid surface is bombarded by primary ions of some keV energy. ... The subsequent mass analysis of the emitted ions provides detailed information on the elemental and molecular composition of the surface. ... Extremely short ion pulses with a duration below . ... By rastering a fine-focussed ion beam over the surface, like an electron beam in an electron microprobe, mass resolved secondary ion images (chemical maps) can be obtained...

... user-defined data file formats . ... better integration with a user's analysis routines To add such functionality to SAOimage, we developed the XPA Messaging System that allows X programs to define points of public access through which data and commands can be exchanged with external programs. ... We have utilized XPA to develop "SAOimage: The Next Generation" (SAOtng), an extensible image display service that can cooperate with other processes and programs. ... SAOtng help pages . ...

Electron Bombarded, Back-Illuminated CCD Sensors . ... EBCCD PERFORMANCE: EBS Gain . ... To the first order, the signal gain in the EBCCD is proportional to the kinetic energy of the photoelectrons prior to their impinging on the CCD back surface. ... To obtain EBS gain in the active material, it is necessary for the photoelectron to enter the pixel from the back surface of the CCD -- away from the gate structures that dissipate the electron energy. ... The EBCCD EBS gain was tested using two methods. ...

Overall 2 % of the total available thermal energy in this region heats water for steam . How many years can this source provide power for electricity generation at the rate of 2000 MW every year?

... Up: Future Instruments and Telescopes, Tools . ... New Generation Astronomical Telescopes (NGAT), a class of telescopes designed to be operated remotely and robotically, require efficient methods for communicating images over heterogeneous and low-bandwidth data networks such as the Internet. ... Methods researched thus far involve the classification of astronomical images based on object parameterisation, progressive image transmission, and evaluation of existing image compression schemes. ...

... We study in this paper the effect of shock excitation of leaky and surface modes by the p-polarized electromagnetic wave incident on the rapidly ionized gaseous or solid layer. ... For example, if [pic] (solid density, multiple ionized plasma), the basic frequency [pic], [pic], [pic] we find, that the wavelength of leaky wave [pic] is in soft x rays band. ... If [pic] (low density gaseous plasma), the basic frequency [pic], [pic], [pic] we find, that the wavelength of leaky wave [pic] is in THz band...

... 2002 October 19 . Io's Surface: Under Construction . Credit: Galileo Project , JPL , NASA . ... Io's surface is constantly under construction . This moon of Jupiter holds the distinction of being the Solar System's most volcanically active body -- its bizarre looking surface continuously formed and reformed by lava flows. ... The notable absence of impact craters suggests that the entire surface is covered with new volcanic deposits much more rapidly than craters are created. ...
