They fulfil most of the demands with respect to cleaning efficiency and long time durability, but their operation regarding the consumption of pulse gas and energy still has to be optimised. Experimental investigations were carried out to measure the flow field, the pressure and the gas temperature inside the filter candle during pulse jet cleaning. These results are compared with the results of a numerical procedure based on a solution of the two - dimensional conservation equations for momentum and energy. The observed difficulties handling different flow regimes like highly turbulent flow as well as Darcy flow simultaneously are discussed.}, language = {en} } @incollection{ButenwegThierauf1999, author = {Butenweg, Christoph and Thierauf, G.}, title = {Automatic design of reinforced concrete structures with parallel computing}, series = {Innovative computational methods for structural mechanics}, booktitle = {Innovative computational methods for structural mechanics}, editor = {Papadrakakis, M. and Topping, B.H.V.}, publisher = {Saxe-Coburg Publication}, address = {Edinburgh}, isbn = {1-874672-05-9}, doi = {10.4203/csets.1.14}, pages = {305 -- 318}, year = {1999}, abstract = {A concept for the analysis and optimal design of reinforced concrete structures is described. It is based on a nonlinear optimization algorithm and a finite element program for linear and nonlinear analysis of structures. With the aim of minimal cost design a two stage optimization using efficient gradient algorithm is developed. The optimization problems on global (structural) and local (crosssectional) level are formulated. A parallelization concept for solving the two stage optimization problem in minimal time is presented. Examples are included to illustrate the practical use and the effectively of the parallelization in the area of engineering design.}, language = {en} } @incollection{KruskaKuperjans1999, author = {Kruska, Martin and Kuperjans, Isabel}, title = {An{\´a}lisis Thermodin{\´a}micos : [Cap{\´i}tulo 3.3]}, series = {Uso racional de energ{\´i}a : eficiencia energ{\´e}tica y energ{\´i}as renovables. - (Manual para consultores y expertos)}, booktitle = {Uso racional de energ{\´i}a : eficiencia energ{\´e}tica y energ{\´i}as renovables. - (Manual para consultores y expertos)}, publisher = {Ministerio de Energ{\´i}a y Minas}, address = {Lima}, pages = {3.3-1 -- 3.3-15}, year = {1999}, language = {es} } @incollection{HoffmannLindemann1999, author = {Hoffmann, Christoph P. and Lindemann, Markus}, title = {Logistik und internetbasiertes Electronic Commerce}, series = {Schweizer Logistik-Katalog : Logistik, f{\"o}rdern, lagern, verteilen. 1999}, booktitle = {Schweizer Logistik-Katalog : Logistik, f{\"o}rdern, lagern, verteilen. 1999}, publisher = {Binkert}, address = {Lauffenburg}, pages = {16 -- 19}, year = {1999}, language = {de} } @incollection{SchwarteHeinolBuxbaumetal.1999, author = {Schwarte, Rudolf and Heinol, Horst-Guenther and Buxbaum, Bernd and Ringbeck, Thorsten and [u.a.],}, title = {Principles of three-dimensional imaging techniques}, series = {Sensors and imaging. - (Handbook of computer vision and applications ; Vol. 1)}, booktitle = {Sensors and imaging. - (Handbook of computer vision and applications ; Vol. 1)}, editor = {J{\"a}hne, Bernd}, publisher = {Academic Press}, address = {San Diego}, isbn = {0-12-379771-3 (Einzelbd.)}, pages = {463 -- 485}, year = {1999}, language = {en} } @incollection{LuczakWolfSchlicketal.1999, author = {Luczak, Holger and Wolf, Martin and Schlick, Christopher and Springer, J. and Foltz, Christian}, title = {Personenorientierte Arbeitsprozesse und Kommunikationsforrnen}, series = {Integration von Entwicklungssystemen in Ingenieuranwendungen : substantielle Verbesserung der Entwicklungsprozesse}, booktitle = {Integration von Entwicklungssystemen in Ingenieuranwendungen : substantielle Verbesserung der Entwicklungsprozesse}, editor = {Nagl, Walter}, publisher = {Springer}, address = {Berlin}, isbn = {3-540-63920-9}, pages = {403 -- 422}, year = {1999}, language = {de} }
