  text: In this paper we describe a beamforming algorithm based on widely-linear rather
    than linear data models. Initially, we develop this beamformer by generalizing
    the Capon (MVDR) optimization problem. That is, if the objective is to minimize
    output power while maintaining a specified directional gain, then we show that
    the output power of the widely-linear beamformer is less than or equal to the
    output power of the Capon (MVDR) beamformer. This result is valid regardless of
    the “true” distribution of the data. We also derive the widely-linear beamformer
    by considering beamforming to be an estimation problem. Linear models assume that
    the composite covariance matrix formed from the real and imaginary parts of the
    array-snapshot has a particular structure. This structure is often summarized
    by stating that the covariance formed from the array snapshot and its transpose
    (not Hermitian transpose) is zero. We could also call these data “proper” Gaussian
    vectors. The beamformers in this paper are appropriate for situations in which
    these implicit assumptions are violated.

  text: The quantum dynamics of an ensemble of interacting electrons in an array of
    random scatterers is treated using a new numerical approach for the calculation
    of average values of quantum operators and time correlation functions in the Wigner
    representation. This approach combines both molecular dynamics and Monte Carlo
    methods and computes numerical traces and spectra of the relevant dynamical quantities
    such as momentum–momentum correlation functions and spatial dispersions. Considering,
    as an application, a system with fixed scatterers, the results clearly demonstrate
    that the many-particle interaction between the electrons can lead to an enhancement
    of the conductivity at intermediate densities.

  text: We present a new and easy to use framework for navigating through scenes of
    arbitrary complexity and topology. In the preprocessing, images for discrete viewpoints
    and viewing directions are rendered and stored on an external volume. During navigation
    each image can be displayed within a very short time by loading it from the volume.
    For acceleration, our prefetching strategy loads possibly needed images for the
    next few frames if the viewer takes a break. The measurements show that we achieve
    interactive frame rates, whereby the difference between the minimal and maximal
    display time is very small. Our system works well with scenes modelled by polygons,
    but also digital photos can easily be used for describing a 3D scene.

  text: Die Implementierung von Algorithmen zur Lösung geometrischer Probleme im Euklidischen
    Raum (z.B. Berechnung der konvexen Hülle oder des Durchschnitts zweier Polyeder)
    stellt sich oftmals als hochgradig nichttrivial heraus. Ob und unter welchen Voraussetzungen
    die verursachenden numerischen Instabilitäten überhaupt ini den Griff zu kriegen
    oder vielmehr dem Problem inhärent sind, untersucht diese Arbeit in einem auf
    Turing zurückgehenden Rechenmodell. Im Gegensatz zu algebraischen Ansätzen geht
    jenes nicht von der Verfügbarkeit exakter Tests auf z.B. Gleichheit reeller Zahlen
    aus, sondern berücksichtigt die auf Digitalcomputern tatsächlich realisierbare
    Approximation durch rationale Zahlen. In diesem Rahmen werden beweisbar stabile
    Algorithmen zum Lösen linearer Gleichungssysteme, zur Matrix-Diagonalisierung
    und zur linearen wie nichtlinearen Optimierung präsentiert. Als wichtiges technisches
    Hilfsmittel dient ein neuer Berechenbarkeitsbegriff für reguläre unendliche Mengen
    reller Zahlen, der sich aus dem systematischen Vergleich verschiedener der Literatur
    entnommener ad-hoc Ansätze ergibt.

  text: Quite often, the implementation of well-known algorithms for solving geometric
    problems in Euclidean space (such as convex hull computation or intersecting two
    polyhedra) turns out to be a highly nontrivial task. Whether and under what prerequisites
    the underlying numerical numerical instabilities can be avoided or are rather
    inherent to the problem is investigated by the present work in a model of computation
    dating back to Alan Turing himself. Other than algebraic approaches, this does
    not rely on (volatile) exact tests for, e.g., equality of real numbers but reflects
    the property of actual digital computers to only approximate real numbers by rationals.
    In this framework, we devise and present provably stable algorithms for solving
    systems of linear equations, matrix diagonalization, and lineare as well as non-linear
    optimization. As major technical tool, a new notion of computability for regular
    infinite sets of real numbers is introduced that arises from formalizing and systematically
    comparing several ad-hoc notions found in previous literature.

  text: Bei der Online-Marktforschung lässt sich mit Hilfe virtueller 3D-Welten das
    Konsumentenverhalten beobachten. Da die Struktur der dabei anfallenden Daten multidimensional
    ist und die marktforschungsrelevanten Anfragen eine hohe OLAP-Affinität aufweisen,
    wurde hierzu im Rahmen des Forschungsprojekts Benevit ein Data Warehouse konzipiert
    und realisiert. Im Rahmen einer Standardisierung der Protokollierung von Konsumentenaktivitäten
    und deren prototypischen Realisierung erwies sich der Data Warehouse/OLAP-Ansatz
    zur Speicherung, Analyse und Präsentation der Marktforschungsdaten als adäquates
    Instrumentenbündel.

  text: Within this paper we propose architecture ideas of a distributed Video on
    Demand network which base on peer to peer technology. Each peer offers video streams
    to other peers and may receive a video stream from another peer simultaneously.
    This results in an optimization problem depending on different factors which we
    approximate with the help of an simulation environment. Our approach bases on
    a peer to peer framework by Sun called Project JXTA which provides a set of protocols
    for P2P applications.
