... There are several classifications of the exact methods. ... A more physical classification is that of Th.Wriedt (1998) where he devides the methods in 3 groups: Mie theory expansions (SVM), surface-based (PMM, EBCM, GMT, MoM) and volume-based (FDTDM, TLMM, FEM and various volume IEMs - CDM, DDA, etc.) methods. Features of the methods . Among the methods only SVM and EBCM are capable to provide very accurate results (5 and more correct decimals) (Mishchenko et al., 2000). ... 1998) Part. ...

Catastrophism : . ... During the late 18th and early 19th century, a German mineralogist, Abraham Gottlob Werner, proposed that all of the Earth's rocks were formed by rapid chemical precipitation from a "world ocean," which he then summarily disposed of in catastrophic fashion. Though not directed toward the genesis of landforms in any coherent fashion, his catastrophic philosophy of changes of the Earth had two major consequences of geomorphic significance. ...

... In this paper, a project aiming to allow access to data archives by means of a query-by-example mechanism is described. The basic user query would simply be the submission of an input image, either 1-D or 2-D; the system should allow retrieval of archived images similar to an input one on the basis of some ``resemblance parameter". ... A system called QUBE is currently being designed to support the QUery-By-Example paradigm in accessing astronomical data archives. ... the QUBE User Interface. ...

... 7.1 Introduction to media types . ... 7.3 Recognized media types . 7.3.1 Media groups One of the most important features of style sheets is that they specify how a document is to be presented on different media: on the screen, on paper, with a speech synthesizer, with a braille device, etc. Certain CSS properties are only designed for certain media (e.g., the 'cue-before' property for aural user agents). ... For example, the 'font-size' property is useful both for screen and print media. ...

... Electronic Raman scattering in the single - CuO 2 layered superconductor Tl 2 Ba 2 CuO 6+ d . ... Electronic Raman scattering in Tl 2 Ba 2 CuO 6+ d (Tl-2201) has been investigated in order to test whether the scattering cross section in high-temperature superconductors depends on the number of CuO 2 planes, i.e., sheets specific details of the Fermi surface. ... The peak in the B 1g symmetry component of the scattering intensity is found at 460 cm -1 ( T c = 90 K), or 430 cm -1 ( T c = 80 K). ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth.
