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

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

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.

Abstract

Hydraulic structures are exposed to multifaceted exposures. Particular the hydro-abrasive wear of the concrete edge zones represents a key exposure. The knowledge about the abrasive mechanisms of concrete and its degradation process is still insufficient. Relating to the hydro-abrasive test method, the relevant material parameter and degradation model incomplete knowledge existed which was removed.

Abstract

This work studies the interaction of natural aerosol with clouds for two different weather regimes in Central Europe. One model study highlights the impact of sea salt aerosol on postfrontal, convective cumulus clouds. The other study examines the influence of mineral dust aerosol on the formation of cirrus clouds during a mineral dust outbreak on 3 April 2014.

Abstract

Sandstone is the most common kind of natural stone used for historic buildings in Central Europe. During the past century a dramatic increase in different types of damage to historic buildings, monuments and sculptures made from natural stone has been observed. The present work deals with theoretical aspects of strength loss, fracture processes and degradation during the decay processes.

Abstract

The consideration of discrete motor primitives in models of human motor control is essential for the realistic prediction of voluntary movements. In this book a formal movement model is derived from neurobiological findings as well as new identification and learning methods are presented for the secured determination of the model parameters. Both the model and the identification methods are demonstrated using the example of predicting human driver steering movements.

Abstract

In this work a newly developed techno-economic optimization model of a household system with electric vehicle (EV) is used to endogenously dimension both the PV system and the stationary battery storage system (SBS). It maximizes the net present values (NPV) of these two systems. The NPV are highly affected by the load shifting potentials of EV and SBS, electricity tariff design and further general conditions.

Abstract

Wireless inductive charging improves user acceptance of electric vehicles, as it allows for a comfortable charging process. A mature inductive power transfer solution has to fulfill various requirements. In order to meet the various demands, at first, an appropriate structure of the magnetic coupler system has to be selected according to the specific case of application Afterwards, a comprehensive design methodology allows a fast and efficient dimensioning of the particular coil topology.
