  text: Viele virtuelle 3-D-Szenen im industriellen Bereich sind nicht gleichmäßig
    strukturiert, z.B. weil sie eine stark unterschiedliche Dichteverteilung der Polygone
    aufweisen. Für solch heterogene Daten existiert kein Algorithmus, der die Gesamtheit
    der Daten sowohl schnell als auch mit guter Qualität darstellen kann. Die Auswahl
    der richtigen Algorithmen für einzelne Szenenteile durch einen Experten ist zeitintensiv
    und in vielen Visualisierungssystemen nicht umzusetzen. Um dieses Problem zu lösen,
    setzt das hier vorgestellte Multi-Algorithmen-Rendering verschiedene Renderingalgorithmen
    gleichzeitig ein, um eine virtuelle 3-D-Szene darzustellen. Das Verfahren unterteilt
    die Szene dafür in einem Vorverarbeitungsschritt automatisch in geeignete Teilregionen
    und bestimmt deren Eigenschaften. Diese Daten werden zur Laufzeit dazu genutzt,
    um ständig für den aktuellen Standpunkt des Betrachters eine Abschätzung der Qualität
    und Laufzeit der zur Auswahl stehenden Renderingalgorithmen zu berechnen. Durch
    die Lösung eines Optimierungsproblems kann so bei vorgegebener Bildrate durch
    die passende Zuordnung der Algorithmen zu den Regionen die Bildqualität optimiert
    werden – bei automatischer Anpassung an die Leistungsfähigkeit der eingesetzten
    Hardware. In einer experimentellen Evaluierung vergleichen wir die Laufzeit und
    Bildqualität des Verfahrens mit denen verbreiteter Standardrenderingverfahren.

  text: 'In this paper, we define and study a new problem, referred to as the Dependent
    Unsplittable Flow Problem (D-UFP). We present and discuss this problem in the
    context of large-scale powerful (radar/camera) sensor networks, but we believe
    it has important applications on the admission of large flows in other networks
    as well. In order to optimize the selection of flows transmitted to the gateway,
    D-UFP takes into account possible dependencies between flows. We show that D-UFP
    is more difficult than NP-hard problems for which no good approximation is known.
    Then, we address two special cases of this problem: the case where all the sensors
    have a shared channel and the case where the sensors form a mesh and route to
    the gateway over a spanning tree.'

  text: We consider the k-token dissemination problem, where k initially arbitrarily
    distributed tokens have to be disseminated to all nodes in a dynamic network (as
    introduced by Kuhn et al., STOC 2010). In contrast to general dynamic networks,
    our dynamic networks are unit disk graphs, i.e., nodes are embedded into the Euclidean
    plane and two nodes are connected if and only if their distance is at most R.
    Our worst-case adversary is allowed to move the nodes on the plane, but the maximum
    velocity v_max of each node is limited and the graph must be connected in each
    round. For this model, we provide almost tight lower and upper bounds for k-token
    dissemination if nodes are restricted to send only one token per round. It turns
    out that the maximum velocity v_max is a meaningful parameter to characterize
    dynamics in our model.

  text: We present a new online algorithm for profit-oriented scheduling on multiple
    speed-scalable processors.Moreover, we provide a tight analysis of the algorithm's
    competitiveness.Our results generalize and improve upon work by \citet{Chan:2010},
    which considers a single speed-scalable processor.Using significantly different
    techniques, we can not only extend their model to multiprocessors but also prove
    an enhanced and tight competitive ratio for our algorithm.In our scheduling problem,
    jobs arrive over time and are preemptable.They have different workloads, values,
    and deadlines.The scheduler may decide not to finish a job but instead to suffer
    a loss equaling the job's value.However, to process a job's workload until its
    deadline the scheduler must invest a certain amount of energy.The cost of a schedule
    is the sum of lost values and invested energy.In order to finish a job the scheduler
    has to determine which processors to use and set their speeds accordingly.A processor's
    energy consumption is power $\Power{s}$ integrated over time, where $\Power{s}=s^{\alpha}$
    is the power consumption when running at speed $s$.Since we consider the online
    variant of the problem, the scheduler has no knowledge about future jobs.This
    problem was introduced by~\citet{Chan:2010} for the case of a single processor.They
    presented an online algorithm which is $\alpha^{\alpha}+2e\alpha$-competitive.We
    provide an online algorithm for the case of multiple processors with an improved
    competitive ratio of $\alpha^{\alpha}$.

  text: We study two-party communication in the context of directed dynamic networks
    that are controlled by an adaptive adversary. This adversary is able to change
    all edges as long as the networks stay strongly-connected in each round. In this
    work, we establish a relation between counting the total number of nodes in the
    network and the problem of exchanging tokens between two communication partners
    which communicate through a dynamic network. We show that the communication problem
    for a constant fraction of n tokens in a dynamic network with n nodes is at most
    as hard as counting the number of nodes in a dynamic network with at most 4n+3
    nodes. For the proof, we construct a family of directed dynamic networks and apply
    a lower bound from two-party communication complexity.

  text: Diese Arbeit besch{\"a}ftigt sich mit dem Facility Location Problem. Dies
    ist ein Optimierungsproblem, bei dem festgelegt werden muss an welchen Positionen
    Ressourcen zur Verf{\"u}gung gestellt werden, so dass diese von Nutzern gut erreicht
    werden k{\"o}nnen. Es sollen dabei Kosten minimiert werden, die zum einen durch
    Bereitstellung von Ressourcen und zum anderen durch Verbindungskosten zwischen
    Nutzern und Ressourcen entstehen. Die Schwierigkeit des Problems liegt darin,
    dass man einerseits m{\"o}glichst wenige Ressourcen zur Verf{\"u}gung stellen
    m{\"o}chte, andererseits daf{\"u}r sorgen muss, dass sich Nutzer nicht all zu
    weit weg von Ressourcen befinden. Dies w{\"u}rde n{\"a}mlich hohe Verbindungskosten
    nach sich ziehen. Das Facility Location Problem wurde bereits sehr intensiv in
    vielen unterschiedlichen Varianten untersucht. In dieser Arbeit werden drei Varianten
    des Problems modelliert und neue Algorithmen f{\"u}r sie entwickelt und bez{\"u}glich
    ihres Approximationsfaktors und ihrer Laufzeit analysiert. Jede dieser drei untersuchten
    Varianten hat einen besonderen Schwerpunkt. Bei der ersten Varianten handelt es
    sich um ein Online Problem, da hier die Eingabe nicht von Anfang an bekannt ist,
    sondern Schritt f{\"u}r Schritt enth{\"u}llt wird. Die Schwierigkeit hierbei besteht
    darin unwiderrufliche Entscheidungen treffen zu m{\"u}ssen ohne dabei die Zukunft
    zu kennen und trotzdem eine zu jeder Zeit gute L{\"o}sung angeben zu k{\"o}nnen.
    Der Schwerpunkt der zweiten Variante liegt auf Lokalit{\"a}t, die z.B. in Sensornetzwerken
    von großer Bedeutung ist. Hier soll eine L{\"o}sung verteilt und nur mit Hilfe
    von lokalen Information berechnet werden. Schließlich besch{\"a}ftigt sich die
    dritte Variante mit einer verteilten Berechnung, bei welcher nur eine stark beschr{\"a}nkte
    Datenmenge verschickt werden darf und dabei trotzdem ein sehr guter Approximationsfaktor
    erreicht werden muss. Die bei der Analyse der Approximationsfaktoren bzw. der
    Kompetitivit{\"a}t verwendeten Techniken basieren zum großen Teil auf Absch{\"a}tzung
    der primalen L{\"o}sung mit Hilfe einer L{\"o}sung des zugeh{\"o}rigen dualen
    Problems. F{\"u}r die Modellierung von Lokalit{\"a}t wird das weitverbreitete
    LOCAL Modell verwendet. In diesem Modell werden f{\"u}r die Algorithmen subpolynomielle
    obere Laufzeitschranken gezeigt.

  text: 'We study the complexity theory for the local distributed setting introduced
    by Korman, Peleg and Fraigniaud. They have defined three complexity classes LD
    (Local Decision), NLD (Nondeterministic Local Decision) and NLD^#n. The class
    LD consists of all languages which can be decided with a constant number of communication
    rounds. The class NLD consists of all languages which can be verified by a nondeterministic
    algorithm with a constant number of communication rounds. In order to define the
    nondeterministic classes, they have transferred the notation of nondeterminism
    into the distributed setting by the use of certificates and verifiers. The class
    NLD^#n consists of all languages which can be verified by a nondeterministic algorithm
    where each node has access to an oracle for the number of nodes. They have shown
    the hierarchy LD subset NLD subset NLD^#n. Our main contributions are strict hierarchies
    within the classes defined by Korman, Peleg and Fraigniaud. We define additional
    complexity classes: the class LD(t) consists of all languages which can be decided
    with at most t communication rounds. The class NLD-O(f) consists of all languages
    which can be verified by a local verifier such that the size of the certificates
    that are needed to verify the language are bounded by a function from O(f). Our
    main results are refined strict hierarchies within these nondeterministic classes.'

  text: In Distributed Cloud Computing, applications are deployed across many data
    centres at topologically diverse locations to improved network-related quality
    of service (QoS). As we focus on interactive applications, we minimize the latency
    between users and an application by allocating Cloud resources nearby the customers.
    Allocating resources at all locations will result in the best latency but also
    in the highest expenses. So we need to find an optimal subset of locations which
    reduces the latency but also the expenses – the facility location problem (FLP).
    In addition, we consider resource capacity restrictions, as a resource can only
    serve a limited amount of users. An FLP can be globally solved. Additionally,
    we propose a local, distributed heuristic. This heuristic is running within the
    network and does not depend on a global component. No distributed, local approximations
    for the capacitated FLP have been proposed so far due to the complexity of the
    problem. We compared the heuristic with an optimal solution obtained from a mixed
    integer program for different network topologies. We investigated the influence
    of different parameters like overall resource utilization or different latency
    weights.

  text: Dominating set based virtual backbones are used for rou-ting in wireless ad-hoc
    networks. Such backbones receive and transmit messages from/to every node in the
    network. Existing distributed algorithms only consider undirected graphs, which
    model symmetric networks with uniform transmission ranges. We are particularly
    interested in the well-established disk graphs, which model asymmetric networks
    with non-uniform transmission ranges. The corresponding graph theoretic problem
    seeks a strongly connected dominating-absorbent set of minimum cardinality in
    a digraph. A subset of nodes in a digraph is a strongly connected dominating-absorbent
    set if the subgraph induced by these nodes is strongly connected and each node
    in the graph is either in the set or has both an in-neighbor and an out-neighbor
    in it. We introduce the first distributed algorithm for this problem in disk graphs.
    The algorithm gives an O(k^4) -approximation ratio and has a runtime bound of
    O(Diam) where Diam is the diameter of the graph and k denotes the transmission
    ratio r_{max}/r_{min} with r_{max} and r_{min} being the maximum and minimum transmission
    range, respectively. Moreover, we apply our algorithm on the subgraph of disk
    graphs consisting of only bidirectional edges. Our algorithm gives an O(ln k)
    -approximation and a runtime bound of O(k^8 log^∗ n) , which, for bounded k ,
    is an optimal approximation for the problem, following Lenzen and Wattenhofer’s
    Ω(log^∗ n) runtime lower bound for distributed constant approximation in disk
    graphs.

  text: Many 3D scenes (e.g. generated from CAD data) are composed of a multitude
    of objects that are nested in each other. A showroom, for instance, may contain
    multiple cars and every car has a gearbox with many gearwheels located inside.
    Because the objects occlude each other, only few are visible from outside. We
    present a new technique, Spherical Visibility Sampling (SVS), for real-time 3D
    rendering of such -- possibly highly complex -- scenes. SVS exploits the occlusion
    and annotates hierarchically structured objects with directional visibility information
    in a preprocessing step. For different directions, the directional visibility
    encodes which objects of a scene's region are visible from the outside of the
    regions' enclosing bounding sphere. Since there is no need to store a separate
    view space subdivision as in most techniques based on preprocessed visibility,
    a small memory footprint is achieved. Using the directional visibility information
    for an interactive walkthrough, the potentially visible objects can be retrieved
    very efficiently without the need for further visibility tests. Our evaluation
    shows that using SVS allows to preprocess complex 3D scenes fast and to visualize
    them in real time (e.g. a Power Plant model and five animated Boeing 777 models
    with billions of triangles). Because SVS does not require hardware support for
    occlusion culling during rendering, it is even applicable for rendering large
    scenes on mobile devices.

  text: "In order to evaluate the efficiency of algorithms for real-time 3D rendering,
    different properties like rendering time, occluded triangles, or image quality,
    need to be investigated. Since these properties depend on the position of the
    camera, usually some camera path is chosen, along which the measurements are performed.
    As those measurements cover only a small part of the scene, this approach hardly
    allows drawing conclusions regarding the algorithm's properties at arbitrary positions
    in the scene. The presented method allows the systematic and position-independent
    evaluation of rendering algorithms. It uses an adaptive sampling approach to approximate
    the distribution of a property (like rendering time) for all positions in the
    scene. This approximation can be visualized to produce an intuitive impression
    of the algorithm's behavior or be statistically analyzed for objectively rating
    and comparing algorithms. We demonstrate our method by evaluating performance
    aspects of a known occlusion culling algorithm.\r\n"

  text: "Many virtual 3D scenes, especially those that are large, are not structured
    evenly. For such heterogeneous data, there is no single algorithm that is able
    to render every scene type at each position fast and with the same high image
    quality. For a small set of scenes, this situation can be improved if different
    rendering algorithms are manually assigned to particular parts of the scene by
    an experienced user. We introduce the Multi-Algorithm-Rendering method. It automatically
    deploys different rendering algorithms simultaneously for a broad range of scene
    types. The method divides the scene into subregions and measures the behavior
    of different algorithms for each region in a preprocessing step. During runtime,
    this data is utilized to compute an estimate for the quality and running time
    of the available rendering algorithms from the observer's point of view. By solving
    an optimizing problem, the image quality can be optimized by an assignment of
    algorithms to regions while keeping the frame rate almost constant.\r\n"

  text: In this paper we introduce “On-The-Fly Computing”, our vision of future IT
    services that will be provided by assembling modular software components available
    on world-wide markets. After suitable components have been found, they are automatically
    integrated, configured and brought to execution in an On-The-Fly Compute Center.
    We envision that these future compute centers will continue to leverage three
    current trends in large scale computing which are an increasing amount of parallel
    processing, a trend to use heterogeneous computing resources, and—in the light
    of rising energy cost—energy-efficiency as a primary goal in the design and operation
    of computing systems. In this paper, we point out three research challenges and
    our current work in these areas.
