... Novel theoretical perspectives include various extremal principles concerning entropy production or dissipation, the Fluctuation Theorem, and the Maximum Entropy formulation of non-equilibrium statistical mechanics. ... MaxEP principle derived from the MaxEnt argument given in Chap. 3 then supplements the Second Law inequality with the statement that not only is hXi non-negative but hXi takes on its maximum value attainable under the imposed constraints.12 1.4.2 Which Entropy Production is...

This site offers information about the International Astronomy Olympiad (IAO), one of the six First International Science Olympiads (like International Olympiads on Mathematics, Physics, Chemistry, Informatics and Biology). It contains the Organization Rules of the IAO which are officially accepted by all participating states and ratified by the leading body of the IAO - the Euro-Asian Astronomical Society. The Rules have to be strictly followed by all participants. ... Update 31-Aug-2004 . ...

We have designed the laboratory model of static Fourier spectrometer for onboard usage for spectral study of atmosphere and ionosphere. The gain of model is to simulate onboard FS which will not have any moving elements (all its optical elements will be mounted at fused quartz monolithic construction), to compare experimental results with theoretical estimations and to measure MTF of CCD array. ... This fact connected with low frequency response of CCD array due to small format of it. ...

Pulkovo NEO Page . ... EPOS Software Package . ... EPOS ( E phemeris P rogram for O bjects of the S olar system) is the Windows PC application for study and ephemeris support of observations of the Solar system objects. ... It controls the part of common data and transfers the control to one of the programs that solve the restricted set of tasks. ... So with the EPOS software package one can calculate the accurate ephemerides for many objects and get the quick illustration of their motion as well. ...

... If the sticky, silicon-based material were ever used to repair Shuttle tiles on orbit, astronauts would apply it with a device like a caulk gun and then smooth it out to reduce turbulence. ... The first part of any on-orbit TPS repair is getting the astronaut to the site of the damage. ... For repairs away from the Space Station, Hill said, the crew would use a "boom" extension on the Shuttle's robot arm ­ currently under development ­ to carry an astronaut to the repair site. ...

. Libration of the Moon (from the Lat. Libratio - vibration) is the observed periodically pendulum like vibrations of the Moon relatively to its mass centre. As a result the Moon is turned to the Earth not strictly by one side but it is slowly rotating on the longitude and latitude, so that 0,59% of all the Moon’s libration: nonuniformity of the Moon motion along the orbit.
