Shaded areas of windows, solar thermal collectors or photovoltaic modules are of major importance for the calculation of solar heating- and cooling-loads of buildings as well as for the determination ...of thermal or electrical output of corresponding solar equipment. SOMBRERO, a PC-program written in Turbo-Pascal, calculates the GSC (geometrical shading coefficient), the proportion of shaded area of an arbitrarily oriented surface surrounded by shading elements as a function of time and location. Shading elements are treated as polygons (not necessarily rectangles) located in a plane and can be combined to bodies such as buildings or trees. They may also represent overhangs and side-wings of the building under consideration. Elements which are far away from the receiver area are treated as horizontal shading profiles. The reduction of (isotropic) diffuse radiation caused by different kinds of obstacles is calculated by means of view-factors. Calculated results of the GSC are stored in ASCII-format and can be used as an input for dynamic solar system simulation programs. This is demonstrated in two illustrative examples showing the coupling of SOMBRERO with SUNCODE and TRNSYS in order to calculate the effects of shading on passive solar heating and passive cooling, respectively.

El objetivo de este trabajo es ilustrar el uso del sistema de programas «SAMA» (Sistema Automatizado para el Monitoreo de las Aguas) para la ayuda en el control de la composición química de la aguas. ...El mismo se basa en la determinación de ecuaciones de dependencia matemática entre la concentración iónica y la conductividad eléctrica. Ha sido implementado en lenguaje Turbo Pascal para microcomputadoras IBM compatibles. El ejemplo de aplicación que se presenta corresponde a aguas de un acuífera kárstico litoral afectado por la intrusión marina las cuales se usan en el regadío de cítricos.
The frontal overthrust structures of a collision ridge and its foreland basin together form an area where the movement of imbricated overthrust structure, erosion, sedimentation, and substratum ...subsidence occur simultaneously. These various phenomena interact and lead to a subsequent sequence of exhumations and burying of the sheets forming these structures. Separate models have been developed in Turbo Pascal for each of these phenomena (imbricate movement, erosion, sedimentation, differential subsidence of the bedrock) and these models are coupled in a general algorithm. By changing the values of the geometrical and mechanical parameters, it is possible to study and quantify the effect of various phenomena on the development and tectonic history of the collision ridge front. Ancillary programs for reconstructing the geometry of the sedimentary bodies of the transported basins and the series of cross sections also were developed and are used to analyze the geometry predicted by the models and to compare them with natural examples.
A program sequence has been developed on a microcomputer that affords automatic acquisition and processing of electroretinogram (ERG) obtained in vivo in dark-adapted albino rats. A 50-Hz digital ...filter and an averaging summation remove the background noise.
This paper presents a Turbo Pascal program, which optimizes an operating radial primary distribution power network. The program suggests changes of conductor sizes so as to have an acceptable voltage ...profile across the entire network with the minimum cost. By using pointers and tree data structures the computation procedure is dynamic and the problem solution fast and complete.
