Many parallel and distributed applications have well defined structure which can be described by few simple relations. Some structures are so common that they are abstracted to parallel and grid benchmarks, other structures, are data and application dependent, become evident only at run-time. Many of these patterns reflect flow of data in the applications. Data Flow Graphs (DFG) provide an abst...

Some marine bacterial species form mucosal layers, called veils, on sulfidic marine sediment. The bacteria attached to this veil actively swim and exert force on the surrounding fluid. The bacteria can break free of the veil and swim, chemotacting back to the veil. Over time the veil forms holes arranged in a hexagonal pattern. Motivated by this system, we present a simplified model to describe...

We perform time-resolved calculations of the information transmitted about visual patterns by neurons in primary visual and inferior temporal cortices. All measurable information is carried in an eeective time-varying ring rate, obtained by averaging the neuronal response with a resolution no ner than about 25 ms in primary visual cortex and around twice that in inferior temporal cortex. We fou...

Electrohydrodynamic effect on natural convection in horizontal channels is investigated from a numerical point of view. The EHD effect is induced by narrow strip electrodes placed at the bottom wall of the channel. The channel is subjected in a first stage only to the electric forces, and in a second stage to the simultaneous action of a temperature gradient and an electric field. The interacti...

This thesis investigates the topic of using entropy estimation for traffic classification. A real-time encrypted traffic detector (RT-ETD) which is able to classify traffic in encrypted and unencrypted traffic is proposed. The performance of the RT-ETD is evaluated on ground truth and real network traces. This thesis is opened by some introductory chapters on entropy, pattern recognition, user ...

Methods We prospectively enrolled 80 patients (51 with rightleft-coronary-cusp fusion pattern [RL-BAV] and 29 with right-non-coronary-cusp fusion pattern [RN-BAV]), and 27 healthy volunteers (HV) with a mean age across groups of 42±16 years. Time-resolved 3-dimensional flow-sensitive magnetic resonance imaging was used to quantify flow abnormalities and local distribution of WSS in the ascendin...
