Er pr{\"a}sentiert nicht nur die Traditionslinien, die ihre Wurzeln in der neuen Sachlichkeit und den ersten Dokumentarfilmtheorien fanden, sondern auch die k{\"u}nstlerische und filmische Vorstellung von Ruttmann. Um den h{\"o}chsten Grad an Objektivit{\"a}t in der Realit{\"a}tsdarstellung zu erreichen, hat dieser Film einerseits treu alle theoretischen und {\"a}sthetischen Gedanken der neusachlichen Kunst zum ersten Mal filmisch in einem DOKUMENTARFILM dargestellt. Noch dazu dr{\"u}ckt der Berlin-Film seinen kulturellen Beitrag mit ausschliesslich filmischen Mitteln aus, also mit rein visuellen Mitteln, oder anders gesagt mit FILMSPRACHE. Im Gegensatz zur ersten Ank{\"u}ndigung des Films und der Filmliteratur, die den Film als Dokumentarfilm ansehen, ist er in Wirklichkeit einer der ersten innovativen Musikfilme in seinem historischen Kontext, welcher mit der Montage von Wirklichkeitsabbilden autonome Musik zu interpretieren versucht. Seine sachlichen, dokumentarischen Reportage-Bilder ordnen sich der abstrakten Struktur und dem Taktmaß der Musik unter. Als Folge entsteht laut Ruttmann eine VISUELLE SINFONIE, die eigentlich vielmehr eine Vision von Berlin darstellte, als zuk{\"u}nftige industrielle Musterstadt. Mit anderen Worten ist Berlin in diesem Film eine realistische Illusion, aber keineswegs ein reales Bild. Er bildet ein neues Filmgenre, den KUNSTDOKUMENTARFILM, das den Grundprinzipien des Dokumentarfilms nicht folgt. Dies unterscheidet ihn aber auch von den K{\"U}NSTLERISCHEN DOKUMENTARFILMEN, die einerseits dem Film BERLIN - DIE SINFONIE DER GROSSTADT zwar formalstilistisch und {\"a}sthetisch {\"a}hneln. Aber im Gegensatz zu ihm erf{\"u}llen diese die elementaren Voraussetzungen f{\"u}r einen Dokumentarfilm. Beispiele daf{\"u}r sind: DER MANN MIT DER KAMERA (1929, Dsiga Vertov), KOYAANISQATSI (1982,Godfry Reggio) und das Remake BERLIN, SINFONIE EINER GROßSTADT (2002, Thomas Schadt). BERLIN - DIE SINFONIE DER GROSSTADT von Walter Ruttmann stellt nicht nur ein neues Filmgenre dar, er ist auch eine singul{\"a}re Erscheinung in der Filmgeschichte. In diesem Sinne spielte er, laut dem Filmkritiker Helmut Korte, eine entscheidende Rolle in der Weiterentwicklung des absoluten Films „als Musterbeispiel f{\"u}r die M{\"o}glichkeiten des k{\"u}nstlerisch-dokumentarischen Films" (Korte 1991: 76).}, subject = {Musikfilm}, language = {de} } @article{WagnerBoreRobinetetal., author = {Wagner, Norman and Bore, Thierry and Robinet, Jean-Charles and Coelho, Daniel and Taillade, Frederic and Delepine-Lesoille, Sylvie}, title = {Dielectric relaxation behavior of Callovo-Oxfordian clay rock: A hydraulic-mechanical-electromagnetic coupling approach}, series = {Journal of Geophysical Research: Solid Earth}, journal = {Journal of Geophysical Research: Solid Earth}, doi = {10.1002/jgrb.50343}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170428-31681}, pages = {4729 -- 4744}, abstract = {Water content is a key parameter to monitor in nuclear waste repositories such as the planed underground repository in Bure, France, in the Callovo-Oxfordian (COx) clay formation. High-frequency electromagnetic (HF-EM) measurement techniques, i.e., time or frequency domain reflectometry, offer useful tools for quantitative estimation of water content in porous media. However, despite the efficiency of HF-EM methods, the relationship between water content and dielectric material properties needs to be characterized. Moreover, the high amount of swelling clay in the COx clay leads to dielectric relaxation effects which induce strong dispersion coupled with high absorption of EM waves. Against this background, the dielectric relaxation behavior of the clay rock was studied at frequencies from 1 MHz to 10 GHz with network analyzer technique in combination with coaxial transmission line cells. For this purpose, undisturbed and disturbed clay rock samples were conditioned to achieve a water saturation range from 0.16 to nearly saturation. The relaxation behavior was quantified based on a generalized fractional relaxation model under consideration of an apparent direct current conductivity assuming three relaxation processes: a high-frequency water process and two interface processes which are related to interactions between the aqueous pore solution and mineral particles (adsorbed/hydrated water relaxation, counter ion relaxation and Maxwell-Wagner effects). The frequency-dependent HF-EM properties were further modeled based on a novel hydraulic-mechanical-electromagnetic coupling approach developed for soils. The results show the potential of HF-EM techniques for quantitative monitoring of the hydraulic state in underground repositories in clay formations.}, subject = {Lehm}, language = {en} } @article{VoelkerBeckmannKoehlmannetal., author = {V{\"o}lker, Conrad and Beckmann, Julia and Koehlmann, Sandra and Kornadt, Oliver}, title = {Occupant requirements in residential buildings - an empirical study and a theoretical model}, series = {Advances in Building Energy Research}, journal = {Advances in Building Energy Research}, number = {7 (1)}, doi = {10.25643/bauhaus-universitaet.3813}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20181015-38137}, pages = {35 -- 50}, abstract = {Occupant needs with regard to residential buildings are not well known due to a lack of representative scientific studies. To improve the lack of data, a large scale study was carried out using a Post Occupancy Evaluation of 1,416 building occupants. Several criteria describing the needs of occupants were evaluated with regard to their subjective level of relevance. Additionally, we investigated the degree to which deficiencies subjectively exist, and the degree to which occupants were able to accept them. From the data obtained, a hierarchy of criteria was created. It was found that building occupants ranked the physiological needs of air quality and thermal comfort the highest. Health hazards such as mould and contaminated building materials were unacceptable for occupants, while other deficiencies were more likely to be tolerated. Occupant satisfaction was also investigated. We found that most occupants can be classified as satisfied, although some differences do exist between different populations. To explain the relationship between the constructs of what we call relevance, acceptance, deficiency and satisfaction, we then created an explanatory model. Using correlation and regression analysis, the validity of the model was then confirmed by applying the collected data. The results of the study are both relevant in shaping further research and in providing guidance on how to maximize tenant satisfaction in real estate management.}, subject = {Post Occupancy Evaluation}, language = {en} } @article{VuBacNguyenXuanChenetal., author = {Vu-Bac, N. and Nguyen-Xuan, Hung and Chen, Lei and Lee, C.K. and Zi, Goangseup and Zhuang, Xiaoying and Liu, G.R. and Rabczuk, Timon}, title = {A phantom-node method with edge-based strain smoothing for linear elastic fracture mechanics}, series = {Journal of Applied Mathematics}, journal = {Journal of Applied Mathematics}, doi = {10.1155/2013/978026}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170426-31676}, abstract = {This paper presents a novel numerical procedure based on the combination of an edge-based smoothed finite element (ES-FEM) with a phantom-node method for 2D linear elastic fracture mechanics. In the standard phantom-node method, the cracks are formulated by adding phantom nodes, and the cracked element is replaced by two new superimposed elements. This approach is quite simple to implement into existing explicit finite element programs. The shape functions associated with discontinuous elements are similar to those of the standard finite elements, which leads to certain simplification with implementing in the existing codes. The phantom-node method allows modeling discontinuities at an arbitrary location in the mesh. The ES-FEM model owns a close-to-exact stiffness that is much softer than lower-order finite element methods (FEM). Taking advantage of both the ES-FEM and the phantom-node method, we introduce an edge-based strain smoothing technique for the phantom-node method. Numerical results show that the proposed method achieves high accuracy compared with the extended finite element method (XFEM) and other reference solutions.}, subject = {Finite-Elemente-Methode}, language = {en} } @techreport{VogelVoelkerArnoldetal., author = {Vogel, Albert and V{\"o}lker, Conrad and Arnold, J{\"o}rg and Schmidt, Jens and Thurow, Torsten and Braunes, J{\"o}rg and Tonn, Christian and Bode, Kay-Andr{\´e} and Baldy, Franziska and Erfurt, Wolfgang and Tatarin, Ren{\´e}}, title = {Methoden und Baustoffe zur nutzerorientierten Bausanierung.
