Full textThe present work describes a generic method for the probabilistic identification of driving situations and driving manoeuvres for safety relevant driver assistance systems. Driving situations and driving manoeuvres underlie a certain uncertainty based on the different situation perception and manoeuvre execution of the driver. This uncertainty component is considered in the approach for the situation and manoeuvre identification. An additional uncertainty aspect is based on the inaccurate environment information, the identification of driving situations and manoeuvres depend on. Both uncertainty aspects are completely independent and are considered and modelled separately for this reason. For modelling both of these uncertainty aspects the present approach is using the fuzzy theory, probabilistic networks, as well as methods for error propagation and sensitivity analysis. After introducing these techniques theoretically, the application and the interaction of the single methods to identify the driving situations and manoeuvres is described in detail. The practicability of the introduced proceeding is shown exemplarily on the emergency brake situation. The emergency brake situation consists of several situation and manoeuvre components. The identification of the single situations and manoeuvres as well as the combination to the higher emergency brake situation is realised with the introduced proceeding. Measuring data gathered on road traffic and close to reality data measured on a test track were used to evaluate the identification quality

Full textFor more than a decade, the collaborative research centres 528 and 532 of the Deutsche For-schungsgemeinschaft (DFG) have worked on the application of textile fabrics in civil engi-neering. The RWTH Aachen (CRC 532) first and foremost dealt with the innovative composite “textile reinforced concrete” with the aim of developing thin-walled concrete components with a heavy-load capacity. The TU Dresden (SFB 528) concentrated on re-search into the strengthening and restoration of reinforced concrete load-bearing structures or timber components to provide an economically and technically attractive alternative for the current challenges in civil engineering. The sixth colloquium on textile reinforced structures (CTRS 6) is part of a series of colloquia which has been alternately organized by the collaborative research centre 528 (Dresden) and 532 (Aachen).After the DFG’s grant had come to an end, the joint sixth and final colloquium of both collaborative research centres, which was this time organized by the CRC 528 from Dresden, took place in Berlin due to its more central location. The scientists from both col-laborative research centres presented their current results which were explained by young scientists from the individual subprojects. The programme was complemented by presenta-tions by renowned international guest lecturers from the field of fibres and textiles.

Full textWinter wheat root growth was measured and modelled to improve site-specific soil and fertilizer management in commercial wheat fields. Field variations in root length densities were analysed at two contrasting sites in East-Germany during two vegetation seasons. A semi-automated root analysing method was developed to facilitate analyses of large numbers of samples. Influences of variations in soil water states, bulk densities and penetration resistances on spatial distributions of roots were quantified. Differences in soil characteristics were large between the two sites and affected root growth considerably. The same field data was used for validating the soil moisture and root growth calculations of the widely applied growth model CERES-Wheat. Simulations of root length densities, soil physical properties and soil water contents were inadequate. The effects of changes of rainfall variabilities on simulated root length densities and soil water contents were tested by uncertainty analysis but were negligible low. A methodology for generating soil information for practical management purposes at a high degree of spatial resolution using limited input information was developed. The corresponding model calculations were carried out based on the Dempster and Shafer theorem. Soil types and texture classes were determined with multimodally and multitemporally captured data of soil electrical conductivities which are required input data of the new model approach. The model generates a digital map with extensive information of spatial variations in soil properties. The validation of the generated soil map with soil data from independent measurements yielded close correlation between measured and calculated values.

Full textThe present thesis deals with solid continuum mechanics applied to metal and crystal plasticity on different length scales. In this respect, the work consists of three larger parts. In the first part, deformation processes are simulated with explicit FEM (Finite Element Method) and a macroscopic phenomenological model of viscoplasticity. Here the focus is on the Equal-Channel Angular Pressing (ECAP) of a metal billet and the compression of a so-called crash box. In both cases it is possible to correctly reproduce the localization of the deformation as already observed in the experiment. Since the concrete microstructure of the material is neglected in the simulations, these localization phenomena are regarded as deformation-induced. The second part deals with the extension of the viscoplastic model so that microscopic processes of the lattice defect structure of the material can be considered. A model of the dynamic behavior of dislocation populations is developed and coupled to the macroscopic viscoplastic model. In this way, aspects of the so-called grain refinement – a complex structure formation process of dislocations and other lattice defects – can be captured. However, the formation of subgrain boundaries, which is decisive for the macroscopic properties, cannot be predicted in this way. To achieve this, a mesoscopic theory of crystal plasticity with continuously distributed dislocations is used and further developed in the third part of the thesis. Here, the degrees of freedom essential for subgrain formation are added, while the number of phenomenological approaches and associated material parameters are kept as small as possible. With this continuum dislocation theory it is possible to follow the formation of subgrain boundaries during large plastic deformations of a crystallite. In the implicit FEM simulations, localization is also observed, but with respect to the dislocation activity in different slip planes. Accordingly, this localization phenomenon is considered dislocation-induced. The contribution of the present work lies on the one hand in the review and comparison of different methodical approaches to the modeling of deformation- and dislocation-induced localization phenomena. On the other hand, an analysis and unification of the geometrically linear continuum dislocation theory according to Berdichevsky & Le is carried out. As it turns out, inherent kinematic limitations of the theory prevent the simulation of subgrain formation. For this reason the consistent geometrically non-linear continuum dislocation theory from Gurtin is adopted and extended. With the derived model of elastically and plastically anisotropic single crystal viscoplasticity it is proven that subgrain formation can be simulated. Moreover, a preparation and synthesis of algorithms for the numerical solution of the associated field equations using the method of finite differences and finite elements is provided. In addition, both approximation methods are compared in terms of advantages and disadvantages as well as thermodynamic consistency when applied to multi-field problems.

Full textThe economic success of companies in the mobile communications industry is determined not only by a reliable provision of services and by the development of innovative business models, but also by the planning, construction, operation and maintenance of high quality and cost-effective radio network infrastructures. This represents an enormous challenge in view of rapid technological progress, changes in customer requirements as well as complexity and longevity of radio networks. Against this background and in order to ensure a long-term cost-effectiveness of infrastructure, a modeling and management concept that allows to analyze and to influence the life cycle costs of radio network infrastructures is developed. This concept consists of three interlinked components. (Systems of) Decision models represent the first component. They are suitable for preparing decision-making about investments in view of complex, infrastructure-related (decision) problems. Approaches of a life cycle oriented target costing for radio network infrastructures as the second component make cost reduction potentials accessible and provide starting points for the market-driven design of infrastructure. The successful application of the concept is supported by IT solutions, which provide appropriate information (third component). Finally, the practical use of the concept is demonstrated and it is investigated whether findings are transferable to other complex technical systems – here machine tools.
