In recent years, networking issues have become more and more important in the design of vehicle control systems. In the beginning of the 1990s a vehicle control system was built up by ‘simple’ computer nodes exchanging ‘simple’ and relatively non-critical data. Today we have moved into distributed vehicle control systems with functions spanning several nodes from different vendors. These system...

Brain function disorders, resulting for instance from stroke, epilepsy, or other incidents can be partially recovered by rehabilitation training. Performing neuro-rehabilitation in virtual reality systems allows for training scenarios close to daily tasks, is easily adaptable to the patients’ needs, is fully controllable by clinical staff, and guarantees patient safety at all times. In this pap...

Synopsis: Some trucking companies have begun to look outside their operations for additional efficiencies by “cooperating with competitors,” i .e. with other carriers. This has been referred to as Collaborative Transportation Management. We present simple examples where a firm (i .e. a trucking company or an organization that has its own private fleet ) can enhance its transportation efficienci...

Research Article Jens Dibbern University of Bern [email protected] Wynne W. Chin University of Houston [email protected] Armin Heinzl University of Mannheim [email protected] The practice of information systems (IS) outsourcing is widely established among organizations. Nonetheless, evidence suggests that organizations differ considerably in the extent to which they deploy IS outsourcin...

Dynamical models are essential for model-based control methodologies which allow smart buildings to operate autonomously in an energy and cost efficient manner. However, buildings have complex thermal dynamics which are affected externally by the environment and internally by thermal loads such as equipment and occupancy.Moreover, the physical parameters of buildingsmay change over time as the ...

Finding a line plan with corresponding frequencies is an important stage of planning a public transport system. A line plan should permit all passengers to travel with an appropriate quality at appropriate costs for the public transport operator. Traditional line planning procedures proceed sequentially: In a first step a traffic assignment allocates passengers to routes in the network, often b...

The increasing design, manufacturing, and provision complexity of high-quality, cost-efficient and trustworthy products and services has demanded the exchange of best organizational practices in worldwide organizations. While that such a realization has been available to organizations via models and standards of processes, the myriad of them and their heavy conceptual density has obscured their...

Processes leading to an increase of demand for a resource as a consequence of increasing the efficiency of using this resource in production or consumption are known as (direct) rebound effects. Rebound effects at micro and macro levels tend to offset the reduction in resource consumption enabled by progress in efficiency. Systems thinking and modeling instruments such as causal loop diagrams a...

Effective traffic management in urban areas is done by adapting traffic signal times to current traffic conditions. At isolated intersections this task is usually realised by fixed time or by conventional vehicle actuated signal controllers. The fixed time signals use predefined green times, they are reliable and cost-efficient but offer no opportunity to adapt on-line. Especially with rapidly ...

We apply the concept of cost efficient claims to Lévy market models and find in an application to German stock prizes considerable potential savings the optimal payoffs provide. The magnitude of savings is related to the strength of the market trend. It is shown that the cost-efficient options also exhibit an improved behaviour concerning hedging errors. In the second part we introduce addition...
