As predicted from thermodynamic considerations, a grain boundary segregated monophase alloy is observed in the annealed mechanically alloyed state for low Ag content by using atom probe tomography. From the detected Ag solute grain boundary enrichment the segregation free enthalpy is estimated to range between -25 and -49 kJ mol^-1 following the McLean equation, in agreement with values reported for coarse-grained Cu–Ag. The extension of the alloying range is described by a two-domain thermodynamic model that considers the excess free volume in the grain boundaries and the strain in the strain interior on the basis of the universal equation of state at negative pressure. To access the grain boundary volumetric strain experimentally, a method based on a combination of density measurements and microscopical quantification of closed pore areas is presented. Moreover, we apply x-ray diffraction line broadening analysis to determine the local strain amplitude, which yields a root-mean-square microstrain of 0.3% for a grain size of 30 nm. It is shown that the grain boundary free volume represents the major origin for the global solubility enhancement in nanocrystalline Cu–Ag at 503 K.}}, author = {{Riedl, Thomas and Kirchner, A and Eymann, K and Shariq, A and Schlesiger, R and Schmitz, G and Ruhnow, M and Kieback, B}}, issn = {{0953-8984}}, journal = {{Journal of Physics: Condensed Matter}}, number = {{11}}, publisher = {{IOP Publishing}}, title = {{{Elemental distribution, solute solubility and defect free volume in nanocrystalline restricted-equilibrium Cu–Ag alloys}}}, doi = {{10.1088/0953-8984/25/11/115401}}, volume = {{25}}, year = {{2013}}, } @inproceedings{4113, author = {{Lindner, Jörg}}, location = {{Kusadasi (Turkey)}}, title = {{{Ion Interactions with Nanopatterned Surfaces}}}, year = {{2013}}, } @misc{500, author = {{Staschewski, Margarita}}, publisher = {{Universität Paderborn}}, title = {{{Price Formation in the Restaurant Industry - An Empirical Analysis}}}, year = {{2013}}, } @phdthesis{501, abstract = {{Handling run-time dynamics on embedded system-on-chip architectures has become more challenging over the years. On the one hand, the impact of workload and physical dynamics on the system behavior has dramatically increased. On the other hand, embedded architectures have become more complex as they have evolved from single-processor systems over multi-processor systems to hybrid multi-core platforms.Static design-time techniques no longer provide suitable solutions to deal with the run-time dynamics of today's embedded systems. Therefore, system designers have to apply run-time solutions, which have hardly been investigated for hybrid multi-core platforms.In this thesis, we present fundamental work in the new area of run-time management on hybrid multi-core platforms. We propose a novel architecture, a self-adaptive hybrid multi-core system, that combines heterogeneous processors, reconfigurable hardware cores, and monitoring cores on a single chip. Using self-adaptation on thread-level, our hybrid multi-core systems can effectively perform performance and thermal management autonomously at run-time. }}, author = {{Happe, Markus}}, isbn = {{978-3-8325-3425-7}}, pages = {{220}}, publisher = {{Logos Verlag Berlin GmbH}}, title = {{{Performance and thermal management on self-adaptive hybrid multi-cores}}}, year = {{2013}}, } @inproceedings{502, abstract = {{Self-adaptation allows continuously running software systems to operate in changing and uncertain contexts while meeting their requirements in a broad range of contexts, e.g., from low to high load situations. As a consequence, requirementsfor self-adaptive systems are more complex than requirements for static systems as they have to explicitly address properties of the self-adaptation layer.While approaches exist in the literature to capture this new type of requirements formally, their achievement cannot be analyzed in early design phases yet. In this paper, we apply RELAX to formally specify non-functional requirements for self-adaptive systems. We then apply our model-based SimuLizar approach for a semi-automatic analysis to test whether the self-adaptation layer ensures that these non-functional requirements are met. We evaluate our approach on the design of a proof-of-concept load balancer system. As this evaluation demonstrates, we can iteratively improve our system design by improving unsatisfactory self-adaption rules.}}, author = {{Becker, Matthias and Luckey, Markus and Becker, Steffen}}, booktitle = {{Proceedings of the 9th ACM SigSoft International Conference on Quality of Software Architectures (QoSA'13)}}, pages = {{43--52 }}, title = {{{Performance Analysis of Self-Adaptive Systems for Requirements Validation at Design-Time}}}, doi = {{10.1145/2465478.2465489}}, year = {{2013}}, } @misc{503, author = {{Blix, Andreas}}, publisher = {{Universität Paderborn}}, title = {{{Optimale und adaptive binäre Bäume in Netzwerken}}}, year = {{2013}}, } @inbook{5031, author = {{Becker, Jörg and Bernhold, Torben and Beverungen, Daniel and Kaling, Nina and Knackstedt, Ralf and Vanessa, Lellek and Peter Rauer, Hans}}, booktitle = {{Dienstleistungsmodellierung 2012: Product-Service Systems und Produktivität}}, editor = {{Thomas, Oliver and Nüttgens, Markus}}, pages = {{208----226}}, title = {{{Softwaregestützte Konstruktion von Produktivitätsmodellen im Facility Management}}}, doi = {{10.1007/978-3-658-00863-5}}, year = {{2013}}, } @misc{504, author = {{Schwichtenberg, Simon}}, publisher = {{Universität Paderborn}}, title = {{{Ontology-based Normalization and Matching of Rich Service Descriptions}}}, year = {{2013}}, } @book{5042, author = {{König, Rolf and Sureth-Sloane, Caren}}, publisher = {{Verlag Neue Wirtschafts-Briefe}}, title = {{{Besteuerung und Rechtsformwahl}}}, year = {{2013}}, } @misc{5043, author = {{Maiterth, Ralf and Sureth-Sloane, Caren}}, booktitle = {{Frankfurter Allgemeine Zeitung}}, number = {{125}}, pages = {{18}}, title = {{{Vermögensteuer vernichtet Eigenkapital}}}, year = {{2013}}, } @techreport{5044, author = {{Meißner, Fabian and Sureth-Sloane, Caren}}, title = {{{The Impact of Corporate Taxes and Flexibility on Entrepreneurial Decisions with Moral Hazard and Simultaneous Firm and Personal Level Taxation}}}, volume = {{141}}, year = {{2013}}, } @misc{5046, author = {{Sureth-Sloane, Caren}}, booktitle = {{Cicero Online}}, title = {{{ Die Reichensteuer gefährdet Arbeitsplätze}}}, year = {{2013}}, } @inproceedings{506, abstract = {{Alle Dom{\"a}nen und Branchen der heutigen Wirtschaft sind auf eine effiziente und effektive Entwicklung von ben{\"o}tigten Softwaresystemen angewiesen.

The goal of VTD is to find a virtual topology that supports forwarding the expected traffic without congestion. In networks with fluctuating, high traffic demands, it can happen that no single topology fits all changing traffic demands occurring over a longer time. Thus, during operation, the virtual topology has to be reconfigured. Since modern networks tend to be large, VTD algorithms have to scale well with increasing network size, requiring distributed algorithms. Existing distributed VTD algorithms, however, react too slowly on congestion for the real-time reconfiguration of large networks. We propose Selfish Virtual Topology Reconfiguration (SVTR) as a new algorithm for distributed VTD. It combines reconfiguring the virtual topology and routing through a Software Defined Network (SDN). SVTR is used for online, on-the-fly network reconfiguration. Its integrated routing and WDM reconfiguration keeps connection disruption due to network reconfiguration to a minimum and is able to react very quickly to traffic pattern changes. SVTR works by iteratively adapting the virtual topology to the observed traffic patterns without global traffic information and without future traffic estimations. We evaluated SVTR by simulation and found that it significantly lowers congestion in realistic networks and high load scenarios.}}, author = {{Wette, Philip and Karl, Holger}}, booktitle = {{Proceedings of the 19th IEEE International Workshop on Local and Metropolitan Area Networks (IEEE LANMAN)}}, pages = {{1 -- 6 }}, title = {{{On the Quality of Selfish Virtual Topology Reconfiguration in IP-over-WDM Networks}}}, doi = {{10.1109/LANMAN.2013.6528271}}, year = {{2013}}, }
