Abstract

An efficient highway capacity design is becoming an increasingly important topic, thanks to recurring congestions and unreliable travel times in the German highway network. This work provides a new methodology for the analysis of oversaturated freeway facilities. A Cell Transmission Model was used as an underlying traffic flow model for modeling oversaturated freeway facilities and tailor-fitted to represent the HBS manual faithfully.

Abstract

The study explores digitization in higher education from the organizational perspective of a university as a “model”, illustrated through specific case studies of the Karlsruhe Institute of Technology and the University of Stuttgart. It is assumed that the key factors affecting digitization in higher education are the widespread adoption and usage of digital technology in science, the digital interconnectedness of higher education systems and the media usage habits of instructors and students.

Abstract

While the present state of knowledge on the time dependent deformation behaviour of normal and high-strength concrete may be considered as sufficiently determined, the creep and shrinkage of lightweight aggregate (LWA) concrete, particularly of high-strength LWA concrete, can only be specified inadequately. On the basis of the experimental results a prediction model for shrinkage and creep of structural lightweight aggregate concrete was developed.

Abstract

As a contribution to environmental protection, the EU tyre label was introduced. However, the best label value does not necessarily imply the lowest rolling resistance under real operating conditions. This research work aims to develop a model to predict the rolling losses of car tyres based on standardized rolling resistance measurements. Using this model, the rolling resistance at variable operating parameters will be predicted.

Abstract

Auf internationaler Ebene wurden Ziele zur Minderung von Luftschadstoff- und klimarelevanten Emissionen vereinbart, deren Umsetzung den jeweiligen Unterzeichnerstaaten obliegt. Hierzu existieren zahlreiche umweltpolitische Instrumente, deren Effektivität und Effizienz jedoch schwer abschätzbar sind. Daher ist es das Anliegen des im vorliegenden Buch beschriebenen otello-Modellsystems, solche politischen Instrumente in ihren ökologischen und ökonomischen Wirkungsmechanismen zu bewerten.

Abstract

In this work, model-based methods for the online identification of physically motivated aging parameters of battery cells are presented and applied to lithium-ion-cells. The new methods are based on fractional impedance models and, in contrast to the state of the art, are late-lumping approaches. A further contribution of this work is the extension of the theory of time-variant fractional systems by a controllability analysis and an energy-optimized control.

Abstract

The compliance with functional safety according to the standard ISO 26262 in context of the increasing electrification of road vehicles is a significant challenge. This work provides a concept and methodology for the model-based development of functional safe hardware. This is characterized by the description of hardware designs, annotation of failure data and performing the demanded safety evaluations.

Abstract

The reuse of process models is a promising technique to reduce modelling effort. Yet, finding similar models in large model collections is not feasible manually. A search functionality for relevant models, which can be used as a template, is therefore helpful. This work describes multiple techniques for finding similar process models and acitvities in process model repositories.

Abstract

This work presents a new approach for a hail loss model to quantify the hail risk on residual buildings for high return periods. Based on the analysis of 3D radar data from 2005 to 2015 a stochastic hail track model is developed to sample a random number of stochastic hail tracks. A detailed vulnerability analysis combines the hazard from the hail tracks and the vulnerability of buildings towards hail and leads to the hail risk for a certain portfolio.

Abstract

In the present work a systematic approach is presented. With this approach it is possible to take concerted simplifications in building models of power train systems of mobile machines. The adopted systematic simplifications are aimed essentially of reducing the order of the system. The basis for this is the introduction of hydraulic replacement elements. Their mathematical structure is based on reduced-dynamic, stationary and event-oriented considerations.
