A novel hybrid method for tracking multiple indistinguishable maneuvering targets using a wireless sensor network is introduced in this paper. The problem of tracking the location of targets is formulated as a Maximum Likelihood Estimation. We propose a hybrid optimization method, which consists of an iterative and a heuristic search method, for finding the location of targets simultaneously. T...

Zusammenfassung. Im Beitrag werden Verfahren zur Visualisierung und Analyse von zerebralen arteriovenösen Malformationen (AVM) präsentiert. Als Eingabe dienen hochaufgelöste 3Dsowie zeitlich-räumliche 4D-MRT-Daten. Ein Ziel dieser Arbeit ist die Kombination von räumlichen und zeitlichen Informationen. Bei der vorgestellten Methode wird zunächst in den 3D-MRT-Daten das Gefäßsystem segmentiert un...

Background Asthma is the most prevalent of all childhood diseases and accounts for the majority of hospitalizations and school absences in children [1]. Current mouse model research has identified the early life gut microbiota as a potential therapeutic target for the prevention of asthma and atopic diseases [2-4]. We hypothesize that the early life gut microbiota could play a similar preventat...

Zusammenfassung. Es werden Methoden zur Visualisierung dynamischer 3D-Volumendaten vorgestellt, die z.B. die Anreicherung eines Kontrastmittels in menschlichen Organen darstellen. Die zugrundeliegenden Daten sind regelmäßig strukturierte CTbzw. MRT-Daten. Der zeitliche Verlauf dynamischer Vorgänge wird anhand von korrespondierenden Intensitätswerten (unterschiedliche Zeitpunkte; gleiche Bildpos...

Submit Manuscript | http://medcraveonline.com Despite their efficacy, approximately 30% of patients do not respond to these therapies, and up to 40% of those who do respond lose efficacy over time [6]. To date, when faced with the failure to respond, the approach was to act empirically by intensifying the employed anti-TNF or by changing to another anti-TNF or a drug with a different therapeuti...

We examine an algorithm for the visualization of domain-coloured Riemann surfaces of plane algebraic curves. The approach faithfully reproduces the topology of the surface and also preserves some of its geometry. We discuss how the algorithm can be implemented efficiently in OpenGL with geometry shaders, and (less efficiently) even in WebGL with multiple render targets and floating point textur...

In designing Markov Decision Processes (MDP), one must define the world, its dynamics, a set of actions, and a reward function. MDPs are often applied in situations where there is a clear choice of reward functions and in these cases significant care must be taken to construct a reward function that induces the desired behavior. In this paper, we consider an analogous design problem: crafting a...
