SUMMARY OF THE RESEARCH PROPOSAL by Maxim Vsemirnov Research topic: Hurwitz and (2,3)-generated matrix groups and related problems. ... The reason to study these groups arises from the fact that the class of (2, 3)-generated groups together with three cyclic groups {1}, C2 and C3 is exactly the class of quotients of the classical modular group PSL2 (Z). ... The answer is known for sporadic groups, some exceptional groups of Lie type and for the most series of classical matrix groups of large rank. ...

... 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. ...

Comments on Mark Walker's Catadioptric Camera for the SKA Element Antenna Graeme James 25 May 2001 Mark Walker has suggested in [1] a catadioptric * optical design as a possible solution to the SKA antenna problem. ... Firstly, for a given collecting area, the physical size of the Luneburg lens and the correcting lens in the catadioptric design in Fig. 1 will be identical. To a good approximation, this correcting lens is in fact a Luneburg lens with a long focal length. ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...

... More recently, I have been concerned with observing masers located in the circumstellar shells generated by red giant stars in their mass-loss phase, and in what we can therefore learn about the late stages of stellar evolution. 100 mJy are now undetectable after ~12 years, aka the DEATH of an OH/IR star or its cyclical evolution back to a Mira variable. ... I find that this momentum flux is sufficient to support the largest observed rates of AGB mass-loss. last updated: 14 January 2015 . ...

A problem, that can arise when moving from Fortran 77 to Fortran 90, is dependent on a usual deviation from the standard, and has to do especially with user programs. ... With many Fortran 77 implementations we wrote PROGRAM TEST REAL X WRITE(*,10) 10 FORMAT('Give X = ',$) READ(*,*) X WRITE(*,*) X END In Fortran 90 we use "non-advancing I/O" instead. ...
