... Up: Algorithms . ... The imaging problem can be described as an optimizing problem in mathematics. ... Computer simulations of rotating modulation collimator imaging show that the quality of images from this method is better than that from the traditional cross-correlation method. ... The imaging problem is: . ... The results show that this algorithm can be used in the imaging problem and usually results in a better image than that obtained from a traditional method such as cross-correlation. ...

A mathematical analogy between a L-and MV-optimal experiments design and an ideal linear correction of system parameters is established, Optimality conditions are derived on the basis of this analogy and effective algorithms for solving these problems are designed. ... The E-optimal problem is reduced to the generalized linear programming problem with M+1 by constraints, where M=m (m+1) /2. ...

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. ...

Next: CCD data Up: Special problems Previous: Marginal nights . If the program complains that you have negative intensities, this is usually due to misidentifying star observations as sky. ... Another problem with sky occurs when the program cannot find a suitable sky observation to subtract from a star datum. ... Finally, as the sky-modelling algorithm does not try to model twilight, it uses the ``nearest-neighbor'' method to correct star observations made during twilight for sky. ...

... The RCB carbon abundance remains an enigma ([ Asplund et al. ... The strength of a stellar absorption line represents the ratio of line opacity to continuous opacity in the atmosphere; both are related to the number density of the absorbing atoms and so provide the number ratio of line absorbers to continuum absorbers. ... Since the predominant continuum absorber in RCB atmospheres is neutral carbon, it has not yet proved possible to measure the carbon abundance from carbon absorption lines. ...
