Vorhersageverbesserung des Windes im Küstenbereich

Viertel, René, Tetzlaff, Gerd 23 March 2017 (has links) (PDF)
Nachdem der weitere Ausbau der Stromerzeugung aus Windenergie an Land an seine Grenzen stösst, rücken die küstennahen Bereiche der Seegebiete in den Mittelpunkt der Planungen. Aufgrund seiner Komplexität sind die Vorhersagen der relevanten Größen im Zeitbereich bis 48 Stunden in diesen Gebieten oftmals ungenau. Mittels systematischer Vergleiche von Prognosen und Messreihen meteorologischer Größen wurde untersucht, ob sich charakteristische Muster der Abweichung der Windprognose von der Messung in Abhängigkeit meteorologischer Größen und Prognosezeit finden und sich die Abweichungen verringern lassen. / After the further development of the generation of current by wind energy on land areas is pushed to the borders the near-shore areas of the see regions moves into the center of plannings. Because of the complex behavior of such areas the prediction of the required meteorological values often becomes uncertain within the forecast range of 48 hours. Measurements of meteorological values and forecasts were compared systematically. By means of this comparisons it was examined, whether characteristical pattern of the deviation between measurements and forcasts, dependent on other meteorological values and forecast time, can be found. The possibility to reduce this deviations was verified.

Essays in Swahili geographical thought.

Tolmacheva, Marina 15 October 2012 (has links) (PDF)
The essays offered here originated in a series of conference papers presented over the years at various professional meetings. In the time elapsed since the first of them was offered at the meeting ofthe UNESCO Commission on the History of Geographical Thought (1988), new important works on Swahili history and language have appeared which demonstrate a variety of productive approaches to the problems of Swahili cultural and ethnic history In a publication such as the Swahili Forum it may be appropriate to recognize the steps made, to acknowledge the advances achieved, and to identify the needs remaining John Middleton`s (1992) well-received book presents a thorough and authmitative analysis of the social, economic, and spatial structures which evolved in the international setting of the East African coast Jarnes de Vere Alien`s posthumously published study (1992) pursues the questions of historic identity of the Swahili and of the political styles developed in the process of interaction of Arab-Islamic and African elements of coastal culture The special role of Islam in the formation and dynamics of Swahili city-states` elites has been analyzed slightly earlier by Randall L Pouwels (1987) Pouwels also has addressed coastal historiography in a series of articles some of which are cited in the following essays The fundamental study of the Swahili language by Derek Nurse and Thomas Hinnebusch (1993) revises and elaborates the possibilities of relating the chronology of the development of Swahili to the history of the Bantu-speaking coastal societies, raised in the earlier works singly or jointly by Derek Nurse and Thomas Spear New editions of Swahili texts make available, sometimes for the first time, to African and Western scholars alike, the synchronic nanatives indispensable for historical accuracy of our interpretations (Omar & Frankl 1990, I olmacheva 1993)

Biashara nzuri - biashara mbaya

Bromber, Katrin 09 August 2012 (has links) (PDF)
Als Bestandteil des Großraums Indischer Ozean wurde die ostafrikanische Küste über Jahrhunderte besonders an ihren Schnittstellen - den `Ankerplätzen` und Hafenstädten - durch kulturelle Austauschbeziehungen geprägt. Diese führten einerseits zu translokalen Anpassungs- und Überlagerungsprozessen, andererseits aber auch zu Konflikten der Ab- und Ausgrenzung. Die Ab- und Ausgrenzung kultureller Gmppen bildet den Ausganspunkt der folgenden Überlegungen. Am Beispiel des swahilisprachigen Pressetextes Biashara (Handel) aus der monatlich in British Tanganyika herausgegebenen Zeitung Mambo Leo (Zeitgeschehen) sollen mit textlinguistischen Mitteln sprachliche Mechanismen der Ab- und Ausgrenzung aufgespürt und ihre Funktion hinterfragt werden.
