Background and Aims: Mouse models of cardiac disease play a major role in cardiovascular research but are frequently imaged with echocardiography rather than with MRI. While several groups have shown that MRI can image the mouse heart with an unparalleled level of breadth and detail, many in the cardiac research community remain concerned by the complexity and time-consuming nature of cardiac M...

Various realtime multimedia applications will be provided in next generation Internet where IEEE 802.11e wireless LAN will be widely used as broadband access networks. The characteristics of the wireless channels in IEEE 802.11 (i.e., fluctuating bandwidth and large error rate), however, impose challenging problems in the efficient QoS-guaranteed realtime multimedia communications with strict Q...

Biometric speaker verification deals with the recognition of voice and speech features to reliably identify a user and to offer him a comfortable alternative to knowledge-based authentication methods like passwords. As more and more personal data is saved on smartphones and other mobile devices, their security is in the focus of recent applications. Continuous Speaker Verification during smartp...

We introduce an online adaptive algorithm for learning gesture models. By learning gesture models in an online fashion, the gesture recognition process is made more robust, and the need to train on a large training ensemble is obviated. Hidden Markov models are used to represent the spatial and temporal structure of the gesture. The usual outputprobabilitydistributions— typically representing a...

In this paper we present a new, simple, and efficient way to illuminate folded surfaces with extended light sources in realtime including shadows. In a preprocessing step we compute the parts of the surrounding environment that are visible from a set of points on the surface and represent this information in a binary visibility map. The illumination of the scene, i.e., incoming light from diffe...

A new generation of real-time computer systems performs physically and logically decentralized mission management—such as semi-autonomous entities collaboratively performing manufacturing, maintenance, combat, etc. These entities must robustly accommodate significant run-time uncertainties in their application environment and system resource state, by being dynamically adaptive. In particular, ...

In the future, real-time, on-line instrument systems connected by wide area networks will be the norm for scientific, medical, and similar data generating systems, because the associated human community, the instruments, and the resources required for data processing are increasingly distributed. The modern instrument environment is characterized by steadily increasing quantities and rates of d...

This paper proposes an approach for constraint-based algorithmic composition in realtime. To our knowledge, constraint programming – which performs a search – has not been used for music composition in realtime before. The main contribution of this paper is a meta-solver with a timeout. We decompose the music creation process into one sub-constraint-problem and solver call per time step. The me...

The accurate and sensitive measurement of hepatitis C virus (HCV) RNA is essential for the clinical management and treatment of infected patients and as a research tool for studying the biology of HCV infection. We evaluated the linearity, reproducibility, precision, limit of detection, and concordance of viral genotype quantitation of the Abbott investigational use only RealTime HCV (RealTime)...

Not that many years ago, many people doubted that a single operating system could support both desktop and server workloads. Linux is well on its way to proving these people wrong. But new times bring new challenges, and so there are now many people who doubt that a single operating system can support both both general-purpose and realtime workloads. This question is still open, although Linux ...
