In order to elaborate this genealogy, the text takes as its starting point not only politics but also life, as the second component of the term. The hypothesis is the following: To understand what biopolitics means, we have to take seriously Foucault's assertion of an indetermination of life, as the correlate of power and knowledge. This notion emerges in the epistemic break that takes place around 1800 and that entails the opening up of the notion of biopolitics under the name of governmentality, implying that life is not only the object of biopolitics but also serves as its model.}, subject = {Biopolitik}, language = {es} } @article{TatliLucks, author = {Tatli, Emin Islam and Lucks, Stefan}, title = {Mobile Identity Management Revisited}, series = {Electronic Notes in Theoretical Computer Science}, journal = {Electronic Notes in Theoretical Computer Science}, doi = {10.1016/j.entcs.2009.07.044}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170426-31640}, pages = {125 -- 137}, abstract = {Identity management provides PET (privacy enhancing technology) tools for users to control privacy of their personal data.

The method is based on the inverse modeling of TDR reflectograms using an optimization algorithm. By means of using flat ribbon cables it is possible to take two independent TDRmeasurements from both ends of the probe, which are used to improve the spatial information content of the optimization results and to consider effects caused by electrical conductivity. The method has been used for monitoring water content distributions on a full-scale levee model made of well-graded clean sand. Flood simulation tests, irrigation tests, and long-term observations were carried out on the model. The results show that spatial TDR is able to determine water content distributions with an accuracy of the spatial resolution of about ±3 cm compared to pore pressure measurements and an average deviation of ±2 vol \% compared to measurements made using another independent TDR measurement system.}, subject = {Damm}, language = {en} } @article{SchanzTripathy, author = {Schanz, Tom and Tripathy, Snehasis}, title = {Swelling pressure of a divalent-rich bentonite: Diffuse double-layer theory revisited}, series = {Water Resources Research}, journal = {Water Resources Research}, doi = {10.1029/2007WR006495}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20170425-31592}, abstract = {Physicochemical forces are responsible for the swelling pressure development in saturated bentonites. In this paper, the swelling pressures of several compacted bentonite specimens for a range of dry density of 1.10-1.73 Mg/m3 were measured experimentally. The clay used was a divalent-rich Ca-Mg-bentonite with 12\% exchangeable Na+ ions. The theoretical swelling pressure-dry density relationship for the bentonite was determined from the Gouy-Chapman diffuse double-layer theory. A comparison of experimental and theoretical results showed that the experimental swelling pressures are either smaller or greater than their theoretical counterparts within different dry density ranges. It is shown that for dry density of the clay less than about 1.55 Mg/m3, a possible dissociation of ions from the surface of the clay platelets contributed to the diffuse double-layer repulsion. At higher dry densities, the adsorptive forces due to surface and ion hydration dominated the swelling pressures of the clay. A comparison of the modified diffuse double-layer theory equations proposed in the literature to determine the swelling pressures of compacted bentonites and the experimental results for the clay in this study showed that the agreement between the calculated and experimental swelling pressure results is very good for dry densities less than 1.55 Mg/m3, whereas at higher dry densities the use of the equations was found to be limited.}, subject = {Bentonit}, language = {en} } @article{KreibichPirothSeifertetal., author = {Kreibich, H. and Piroth, K. and Seifert, I. and Maiwald, Holger and Kunert, U. and Schwarz, Jochen and Merz, B. and Thieken, A.

However, this influence is hardly quantified and virtually no damage models take it into account. Therefore, the influences of flow velocity, water depth and combinations of these two impact parameters on various types of flood damage were investigated in five communities affected by the Elbe catchment flood in Germany in 2002. 2-D hydraulic models with high to medium spatial resolutions were used to calculate the impact parameters at the sites in which damage occurred. A significant influence of flow velocity on structural damage, particularly on roads, could be shown in contrast to a minor influence on monetary losses and business interruption. Forecasts of structural damage to road infrastructure should be based on flow velocity alone. The energy head is suggested as a suitable flood impact parameter for reliable forecasting of structural damage to residential buildings above a critical impact level of 2m of energy head or water depth. However, general consideration of flow velocity in flood damage modelling, particularly for estimating monetary loss, cannot be recommended.}, subject = {Str{\"o}mungsgeschwindigkeit}, language = {en} } @article{KoenigBauriedel, author = {K{\"o}nig, Reinhard and Bauriedel, Christian}, title = {Generating settlement structures: a method for urban planning and analysis supported by cellular automata}, series = {Environment and Planning B: Planning and Design}, journal = {Environment and Planning B: Planning and Design}, doi = {10.25643/bauhaus-universitaet.2605}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20160624-26054}, pages = {602 -- 624}, abstract = {Previous models for the explanation of settlement processes pay little attention to the interactions between settlement spreading and road networks. On the basis of a dielectric breakdown model in combination with cellular automata, we present a method to steer precisely the generation of settlement structures with regard to their global and local density as well as the size and number of forming clusters. The resulting structures depend on the logic of how the dependence of the settlements and the road network is implemented to the simulation model. After analysing the state of the art we begin with a discussion of the mutual dependence of roads and land development. Next, we elaborate a model that permits the precise control of permeability in the developing structure as well as the settlement density, using the fewest necessary control parameters. On the basis of different characteristic values, possible settlement structures are analysed and compared with each other. Finally, we reflect on the theoretical contribution of the model with regard to the context of urban dynamics.}, language = {en} } @article{BimberIwai2009, author = {Bimber, Oliver and Iwai, Daisuke}, title = {Superimposing Dynamic Range}, series = {Eurographics 2009}, journal = {Eurographics 2009}, doi = {10.25643/bauhaus-universitaet.1532}, url = {http://nbn-resolving.de/urn:nbn:de:gbv:wim2-20120130-15325}, year = {2009}, abstract = {Replacing a uniform illumination by a high-frequent illumination enhances the contrast of observed and captured images.
