@techreport{603, abstract = {{Preemptive Routing and Wavelength Assignment (RWA) algorithms preempt established lightpaths in case not enough resources are available to setup a new lightpath in a Wavelength Division Multiplexing (WDM) network. The selection of lightpaths to be preempted relies on internal decisions of the RWA algorithm. Thus, if dedicated properties of the network topology are required by the applications running on the network, these requirements have to be known by the RWA algorithm. Otherwise it might happen that by preempting a particular lightpath these requirements are violated. If, however, these requirements include parameters only known at the nodes running the application, the RWA algorithm cannot evaluate the requirements. For this reason a RWA algorithm is needed which involves its users in the preemption decisions. We present a family of preemptive RWA algorithms for WDM networks. These algorithms have two distinguishing features: a) they can handle dynamic traffic by on-the-fly reconfiguration, and b) users can give feedback for reconfiguration decisions and thus influence the preemption decision of the RWA algorithm, leading to networks which adapt directly to application needs. This is different from traffic engineering where the network is (slowly) adapted to observed traffic patterns. Our algorithms handle various WDM network configurations including networks consisting of heterogeneous WDM hardware. To this end, we are using the layered graph approach together with a newly developed graph model that is used to determine conflicting lightpaths.}}, author = {{Wette, Philip and Karl, Holger}}, publisher = {{Universität Paderborn}}, title = {{{Introducing feedback to preemptive routing and wavelength assignment algorithms for dynamic traffic scenarios}}}, year = {{2012}}, } @book{6138, author = {{Weber, W and Kabst, Rüdiger}}, isbn = {{978-3-8349-1994-6}}, title = {{{Einführung in die Betriebswirtschaftslehre}}}, year = {{2012}}, } @inproceedings{636, abstract = {{We consider an online facility location problem where clients arrive over time and their demands have to be served by opening facilities and assigning the clients to opened facilities. When opening a facility we must choose one of K different lease types to use. A lease type k has a certain lease length lk. Opening a facility i using lease type k causes a cost of f k i and ensures that i is open for the next lk time steps. In addition to costs for opening facilities, we have to take connection costs ci j into account when assigning a client j to facility i. We develop and analyze the first online algorithm for this problem that has a time-independent competitive factor.This variant of the online facility location problem was introduced by Nagarajan and Williamson [7] and is strongly related to both the online facility problem by Meyerson [5] and the parking permit problem by Meyerson [6]. Nagarajan and Williamson gave a 3-approximation algorithm for the offline problem and an O(Klogn)-competitive algorithm for the online variant. Here, n denotes the total number of clients arriving over time. We extend their result by removing the dependency on n (and thereby on the time). In general, our algorithm is O(lmax log(lmax))-competitive. Here lmax denotes the maximum lease length. Moreover, we prove that it is O(log2(lmax))-competitive for many “natural” cases. Such cases include, for example, situations where the number of clients arriving in each time step does not vary too much, or is non-increasing, or is polynomially bounded in lmax.}}, author = {{Meyer auf der Heide, Friedhelm and Pietrzyk, Peter and Kling, Peter}}, booktitle = {{Proceedings of the 19th International Colloquium on Structural Information & Communication Complexity (SIROCCO)}}, pages = {{61--72}}, title = {{{An Algorithm for Facility Leasing}}}, doi = {{10.1007/978-3-642-31104-8_6}}, year = {{2012}}, } @inbook{7557, abstract = {{Software systems are part of our everyday life and they become more complex day by day. The ever-growing complexity of software and high quality requirements pose tough challenges to quality assurance. The quality of a software system can be measured by software testing. However, if manually done, testing is a time-consuming and error-prone task. Especially test case design and test execution are the most cost-intensive activities in testing. In the previous 20 years, many automation tools have been introduced for automating test execution by using test scripts. However, the effort for creating and maintaining test scripts remains. Model-based testing (MBT) aims at improving this part by systematizing and automating the test case design. Thereby, test cases or automatable test scripts can be generated systematically from test models. MBT is already known for several years, but it currently gains a great momentum due to advanced tool support and innovative methodological approaches. This chapter aims at giving an overview of MBT and summarizes recent achievements in MBT. Experiences with using the MBT approach are illustrated by reporting on some success stories.

Das Einsatzgebiet von Polyamiden ist sehr vielseitig. Neben dem massiven Einsatz in der Textilindustrie sei beispielsweise auch der Einsatz in Seilen und Trassen, Zahnrädern und Lagern genannt. Weiterhin findet PA 6 kompositäre Verwendung als Matrixmaterial in thermoplastischen Faserverbundmaterialien (u. a. endlosfaserverstärkte Organobleche) und ist dabei vor allem für die Automobilindustrie von immens steigender Bedeutung. Neben der bei PA ausgeprägten reversiblen Polykondensation, d.h. der Reaktion des Kunststoffes mit Wasser aus der Umgebungsluft, treten irreversible Prozesse (Thermooxidation, Photooxidation, Nachkondensation, $\ldots$) auf, welche seine chemischen und mechanischen Eigenschaften beeinflussen. In diesem Beitrag sollen die Auswirkungen hydrothermischer Alterung durch Temperatur und Feuchtigkeit, auf die akustischen bzw. mechanischen Eigenschaften zum einen im hochfrequenten (Ultraschall) und zum anderen im quasistatischen Bereich charakterisiert werden. Dazu werden PA 6 Probekörper mittels Klimawechseltests künstlich gealtert und in zwei verschiedenen Versuchsaufbauten beurteilt. Zum einen werden hohlzylindrische Proben zur Charakterisierung im Ultraschallbereich (Schallgeschwindigkeit, Schallkennimpedanz, Schallabsorption) und zum anderen Schulterstäbe zur Charakterisierung der mechanischen Materialeigenschaften im quasistatischen Bereich verwendet.
