Driver cognitive workload

Ruff, Stefan (2017)

Using in-car speech interaction systems has become increasingly popular. However, the cognitive workload resulting from this and its consequences for the driver are not yet fully understand. This thesis therefore aims to better understand the consequences of driver cognitive workload regarding performance, subjective evaluation and physiological changes and to identify suitable non-intrusive ph...

The loading, shape and motion of the lumbar spine

Dreischarf, Marcel (2017)

Low back pain (LBP) is one of the most challenging health-economic problems of modern societies that are subjected to demographic change. Due to its multifactorial causes and a lack of scientific knowledge, currently employed therapy concepts for LBP, for pain in the lumbar spine in particular, are insufficiently successful. However, recent clinical-biomechanical research has emphasized that a ...

Material reutilization cycles across industries and production lines

Halstenberg, Friedrich A. ; Steingrímsson, Jón G. ; Stark, Rainer (2017)

The concept of Industrial Symbiosis aims at organizing industrial activity like a living ecosystem where the by-product outputs of one process are used as valuable raw material input for another process. A significant method for the systematic planning of Industrial Symbiosis is found in input–output matching, which is aimed at collecting material input and output data from companies, and using...

Target-driven sustainable product development

Buchert, Tom ; Pförtner, Anne ; Stark, Rainer (2017)

Figuring in sustainability in product development requires a profound understanding of the cause and effect of engineering decisions along the full spectrum of the product lifecycle and the triple bottomline of sustainability. Sustainability design targets can contribute to mitigating the complexity involved, by means of a formalised problem description. This article discusses how sustainabilit...

Sustainable technologies for thick metal plate welding

Sproesser, Gunther ; Chang, Ya-Ju ; Pittner, Andreas ; Finkbeiner, Matthias ; Rethmeier, Michael (2017)

Welding is the most important joining technology. In the steel construction industry, e.g. production of windmill sections, welding accounts for a main part of the manufacturing costs and resource consumption. Moreover, social issues attached to welding involve working in dangerous environments. This aspect has unfortunately been neglected so far, in light of a predominant focus on economics co...

Reduction of friction by normal oscillations. II. In-plane system dynamics

Mao, Xinyu ; Popov, Valentin L. ; Starcevic, Jasminka ; Popov, Mikhail (2017)

The influence of out-of-plane oscillations on friction is a well-known phenomenon that has been studied extensively with various experimental methods, e.g., pin-on-disk tribometers. However, existing theoretical models have yet achieved only qualitative correspondence with experiment. Here we argue that this may be due to the system dynamics (mass and tangential stiffness) of the pin or other s...

Brain connectivity during encoding and retrieval of spatial information: individual differences in navigation skills

Sharma, Greeshma ; Gramann, Klaus ; Chandra, Sushil ; Singh, Vijander ; Mittal, Alok Prakash (2017)

Emerging evidence suggests that the variations in the ability to navigate through any real or virtual environment are accompanied by distinct underlying cortical activations in multiple regions of the brain. These activations may appear due to the use of different frame of reference (FOR) for representing an environment. The present study investigated the brain dynamics in the good and bad navi...
