In this paper, a novel biomechanical modeling and simulation environment with an emphasis on user-specific customization is presented. A modular modeling approach for multi-body systems allows a flexible extension by specific biomechanical modeling elements and enables an efficient application in dynamic simulation and optimization problems. A functional(More)
Mobility is considered a key technology of the next generation Internet and has been standardized within the IETF. Rapidly emerging multimedia group applications such as IPTV, massive mutliplayer games (MMORPGs) and video conferencing increase the demand for mobile group communication, but a standard design of mobile multicast is still awaited. The open(More)
Feelings of unrealistic body parts are related to deficits in human information processing and can occur as a part of phantom sensations after amputation [8]. Experimentally induced sensoric illusions like rubber hand illusion (RHI) [1] may help to understand basic information processing and could give new ideas for treatment or the rehabilitation process.(More)
Neuroscience research often requires direct access to brain tissue in animal models which clearly requires opening of the protective cranium. Minimizing animal numbers requests only well-experienced surgeons, since clumsy performance may lead to premature death of the animal. To minimise those traumatic outcomes, an algorithmic approach for closed-loop(More)
Multicast network services advantageously complement multimedia information and communication technologies, as they open up the realm for highly scalable multi- customer applications. Mobile environments providing shared limited bandwidth to a growing number of users will emphasize the need for multicast support even further. The traditional Internet(More)
Differential near infrared sensors recently sparked a growing interest as a promising measuring modality for brain computer interfacing. In our study we present the design and characterization of novel, differential functional NIRS sensors, intended to record hemodynamic changes of the human motor cortex in the hand-area during motor imagery tasks. We(More)
When it comes to academic signal processing, students' experiences are sometimes spoilt by the dry nature of the topic, applying only mathematical methods. We propose in the following a more hands-on method to acquire signal processing experiences by utilizing state-of-the-art Digital Signal Processor hardware for biomedical engineering related tasks. In(More)
Multimedia networking in the near future is expected to be dominated by group applications such as IPTV, MMORPGs, and video conferencing. Hand in hand with new service offers, the deployment of multicast at the network layer started to disseminate. Currently info-tainment is gradually expanding into the mobile world, but a standard design of mobile(More)
