especially useful as the number of queries in the system increases, but this is precisely when projection will be least selective, forcing the downstream engine to parse most or all of the input data even after [...] effective circuit optimization technique. Figure 12(b) illustrates the idea."); and (2) starting to process another document immediately (one machine cycle?) after the previous document, i.e., before it completes [...] when applying an XPath predicates containing a "//" (descendant-or-self) path. It seems to me that processing of document 2 could be stalled by document 1, if the // tag on document was satisfied only after …

VLDB 2009 Reviews

each point) My only complaint is the treatment given to the Linux system used for comparison. It would be nice if the bottleneck in the system could be explained. The bottleneck is likely to be the number [...] application Three weak points of the paper (please number them W1,W2,W3) W1: Comparison against Linux system is weak. More explanation on performance problems would have been good. W2: It is unclear if the [...] paper's main contributions and impact (up to one paragraph) This paper explores the use of FPGAs to process query streams. The paper is motivated by multicore CPUs with the ideas that some cores might be …

Scalable and Precise Multi-UAV Indoor Navigation using TDOA-based UWB Localization

unmanned aerial vehicle (UAV) systems provide several sensors for stabilization and navigation. However, absolute indoor positioning poses a problem for autonomous robotic systems. The specific challenge addressed [...] addressed in this paper is enabling novel applications with autonomous UAV systems through tight integration with scalable and precise receiver-side time-difference of arrival (TDOA) based ultra-wideband [...] proposed approach in a logistics environment.

Congratulations to Max Rademacher, Joris Daus and Ngoc Le

University. Joris Daus investigated “Dynamics of pulsed excitation in a quantum three-level system.” Three-level systems are a cornerstone of quantum optics and naturally occur in quantum dots when spin states [...] Rademacher worked on the topic “Theoretical description of nonlinear optical signals in cuprous oxide systems.” He investigated how coupling in semiconductor materials can be revealed through nonlinear four-wave [...] two-mode Jaynes–Cummings model. Confirming that this bichromatic excitation acts as a one-photon process, she gained detailed insights into the dynamics of the involved states. …

topic of my research group is the quantum theory of condensed matter systems. On the one hand, we are concerned with solid-state systems in which strong correlations prevail, so that metals become Mott insulators [...] magnonics. On the other hand, physics far from normal equilibrium is fascinating: can open quantum systems be brought into special quantum states when driven by laser pulses on the one hand and relax in contact [...] large reservoirs on the other hand? A particularly exciting subfield of this is quantum information processing, with the questions of whether spins can be used as quantum bits or how to optimize quantum gates …
