1. ASP: Effecting Global Change
Changing a World . What did the students learn from all this? ... The students found this unsatisfactory -- some of them would not be able to fit another astronomy class into their schedules, but they wanted to know about our planetary neighbors, and this project gave them the opportunity to find out without spending valuable class time on the subject. ... The students also learned to learn for themselves, perhaps one of the most important milestones during formal education. ...

2. An Example of a Perplexing Problem
Next: A Plea to Up: Some Problems of Practical Previous: Problems of Fourier . I would like to spend the rest of my time showing an example of the kind of dilemma one can get into when doing restorations. In this particular case we were dealing with an FOC ultraviolet image of the center of M31, and a PC V -band image of the same region, scaled, rotated, and aligned. We wanted to take the quotient of the two images, to look for color effects. ... Image A has low , while B has high . ...

3. Equations of condition
... Assured of a reliable method of solving the normal equations, we now consider the equations of condition. The observed magnitude m of a star at M air masses with true instrumental magnitude is modelled as ([ 10 ], [ 28 ]) . ... The effective extinction coefficient depends on the effective spectral gradient [ 29 ] of the star, for which we use some color index, affected by half the atmospheric reddening ([ 26 ], [ 10 ]): . ... Thus, for the B band of UBV, we use the (U-V) color. ...

8. East Siberian Center for the Earth's Ionosphere Research. Problems of the IS
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. ...

11. Conference Global Fields
In this talk we will present a series of results and open problems emerging from the study of infinite global fields. We will give a survey of the asymptotic properties of the Brauer-Siegel and Euler-Kronecker invariants in the classical situation of number fields and function fields as well as in certain higher dimensional cases. ...

Higher Criticism Statistic: Theory and Applications in Cosmology and Astronomy Jiashun Jin Department of Statistics Purdue University October 2, 2005 Abstract Higher Criticism is a recent statistic proposed by Donoho and Jin [1] where it has been shown to be effective at resolving a very subtle testing problem: test whether n normal means are all zero versus the alternative that a small fraction is non-zero. Higher Criticism is also useful for non-Gaussian detection. ... 2004). ...

20. Database of Optical Properties -- Level: subsubpage
The efficiency of interaction of radiation with a particle and hence its optical properties depend on the particle chemical composition, size, shape, structure, etc. ... Particle size expressed in units of the wavelength of incident radiation, together with chemical composition, most strongly affects the optical properties of a scatterer. ... There are many methods to solve the light-scattering problem for a homogeneous spheroid (our survey of the light-scattering methods see here ). ...
