Home ETH Deutsch News Archive: News of the ETH-Bibliothek Year 2004 New portal for Web of Science and other ISI databases: Web of Knowledge The ETH-Bibliothek is now presenting the multidisciplinary database Web of Science under the Web of Knowledge portal. This user-friendly integrated portal also provides access to additional ISI databases (Current Contents Connect, Derwent Innovations Index, Essential Science Indicators, ISI Proceedings, Journal Citation Reports) as well as to the important Biosis Previews and Inspec databases. The products are linked with one another and can be searched simultaneously to a large extent. SFX functionality leads the user directly from database references to the relevant types of access (full text, online article delivery, etc.). Please note that due to this change in platform, Biosis Previews and Inspec will no longer be searchable under the Silverplatter interface from the beginning of January 2005. New Search Interface for Medline Database As of now, the ETH-Bibliothek is presenting a new search interface (EBSCOhost) for the Medline database. The new appearance replaces the previous SilverPlatter interface, which will be disconnected at the end of this year.

Map Projections Conformal Projections Introduction A map projection faithfully reproducing all features of the original sphere would be perfectly equidistant ; i.e., distances between every two points would keep the same ratio on both map and sphere. Therefore, all shapes would also be preserved. On a flat map this property is simply not possible (as proved by points at the map's edge). For many mapping applications (like topography and certain kinds of navigation), a lesser constraint - fidelity of shape, or conformality , is the most fundamental requisite: the angle between any two lines on the sphere must be the same between their projected counterparts on the map; in particular, each parallel must cross every meridian at right angles. Also, scale at any point must be the same in all directions. Conformality is a strictly local property: angles (therefore shapes) are not expected to be preserved much beyond the intersection point; in fact, straight lines on the sphere are usually curved in the plane, and vice versa. Conformal map projections are frequently employed in large-scale applications, and seldom used for continental or world maps (those shown here are included for comparison only). Since no conformal map can be

COMPLEX ANALYSIS: Mathematica 4.1 Notebooks (c) John H. Mathews, and ... APPLICATIONS of HARMONIC FUNCTIONS Section 10.9 Schwarz-Christoffel Transformation To proceed further, we must review the rotational effect of a conformal mapping w=f(z) at a point Many applications involving conformal mappings require the construction of a one-to-one conformal mapping from the upper half plane onto a domain G in the w-plane where the boundary consists of straight line segments. Let us consider the case where G is the interior of a polygon P with vertices specified in the positive (counterclockwise) sense. We want to find a function with the property , and Two German mathematicians Herman Amandus Schwarz (1843-1921) and Elwin Bruno Christoffel (1829-1900) independently discovered a method for finding f, and that is our next theorem.

Difference Equations and Recursive Relations Difference Equations and Recursive Relations index History Topics Index Difference equations and recursive relations were first studied extensively by the ancient Greek mathematicians. The major contributors to the theory of difference equations and recursive relations during the period of 1876-1900 were: Hermite Christoffel Routh Laguerre ... Chebychev and Peano. Charles Hermite is known for introducing Hermite equations y" - 2xy' + 2 n y = where n is a constant, not necessarily an integer. Hermite functions is the solutions of an equation related to Hermite's equations. By the method of solution in series, the general solution of Hermite's equation is y(x) = c y (x) + c y (x) where c and c are arbitraty constants and the functions y (x) and y (x) are defined by the equations y (x) = 1 - 2 n/ 2! x n(n-2)/4! x n(n-2)(n-4)/6! x y (x) = x [ 1 - 2 ( n-1)/3 ! x n-1)(n-3)/5! x In solutions of the Hermite equation, when n is a positive integer; it then has a polynomial solution.
