The maximal number of allowed hops might be bounded with the motivation to guarantee small latency. We introduce hybrid connectivity games to study the impact of selfishness on this kind of infrastructure. Mobile devices are represented by selfish players, each of which aims at establishing an uplink path to the base station minimizing its individual cost. Our model assumes that intermediate nodes on an uplink path are reimbursed for transmitting the packets of other devices. The reimbursements can be paid either by a benevolent network operator or by the senders of the packets using micropayments via a clearing agency that possibly collects a small percentage as commission. These different ways to implement the payments lead to different variants of the hybrid connectivity game. Our main findings are: (1) If there is no constraint on the number of allowed hops on the path to the base station, then the existence of equilibria is guaranteed regardless of whether the network operator or the senders pay for forwarding packets. (2) If the network operator pays, then the existence of equilibria is guaranteed only if at most one intermediate node is allowed, i.e., for at most two hops on the uplink path of a device, but not if the maximal number of allowed hops is three or larger. (3) In contrast, if the senders pay for forwarding their packets, then equilibria are guaranteed to exist given any bound on the number of allowed hops. The equilibrium analysis presented in this paper gives a first game theoretical motivation for the implementation of micropayment schemes in which senders pay for forwarding their packets. We further support this evidence by giving an upper bound on the Price of Anarchy for this kind of hybrid connectivity games that is independent of the number of nodes, but only depends on the number of hops and the power gradient.}}, author = {{Ackermann, Heiner and Briest, Patrick and Fanghänel, Alexander and Vöcking, Berthold}}, isbn = {{9783540771043}}, journal = {{Internet Mathematics}}, number = {{4}}, pages = {{459--475}}, publisher = {{Springer}}, title = {{{Who Should Pay for Forwarding Packets?}}}, doi = {{10.1007/978-3-540-77105-0_21}}, volume = {{5}}, year = {{2008}}, } @inproceedings{7995, abstract = {{Enterprise Architecture (EA) has undergone many changes since the IT has found its way into enterprises.

As a consequence, there is a demand for consolidating different versions of process models by detecting and resolving differences. Existing approaches rely on the existence of a change log which logs the changes when changing a process model. However, in several scenarios such a change log does not exist and differences must be identified by comparing process models before and after changes have been made. In this paper, we present our approach to detecting and resolving differences between process models, in the absence of a change log. It is based on computing differences and deriving change operations for resolving differences, thereby providing a foundation for variant and version management in these cases.}}, author = {{Küster, Jochen and Gerth, Christian and Förster, Alexander and Engels, Gregor}}, booktitle = {{Proceedings of the 6th International Conference on Business Process Management (BPM'08)}}, pages = {{244--260}}, publisher = {{Springer}}, title = {{{Detecting and Resolving Process Model Differences in the Absence of a Change Log}}}, doi = {{http://dx.doi.org/10.1007/978-3-540-85758-7_19}}, volume = {{5240}}, year = {{2008}}, } @inproceedings{8002, author = {{Koehler, Jana and Gschwind, Thomas and Küster, Jochen and Pautasso, Cesare and Ryndina, Ksenia and Vanhatalo, Jussi and Völzer, Hagen}}, booktitle = {{Proceedings of the 3rd International Symposium on Applications of Graph Transformations with Industrial Relevance 2007 (AGTIVE '07), Kassel (Germany)}}, pages = {{1--16}}, publisher = {{Springer}}, title = {{{Combining Quality Assurance and Model Transformations in Business-Driven Development}}}, doi = {{http://dx.doi.org/10.1007/978-3-540-89020-1_1}}, volume = {{5088}}, year = {{2008}}, } @inproceedings{8006, author = {{Voigt, Hendrik and Ruhroth, Thomas}}, booktitle = {{Proceedings of the 27th International Conference on Conceptual Modeling (ER 2008), Barcelona, Spain}}, pages = {{526--527}}, publisher = {{Springer}}, title = {{{A Quality Circle Tool for Software Models}}}, doi = {{http://dx.doi.org/10.1007/978-3-540-87877-3_44}}, volume = {{5231}}, year = {{2008}}, } @inproceedings{8007, author = {{Wahler, Michael and Küster, Jochen}}, booktitle = {{Proceedings of the 6th International Conference on Business Process Management}}, pages = {{148--163}}, publisher = {{Springer}}, title = {{{Predicting Coupling of Object-Centric Business Process Implementations}}}, doi = {{http://dx.doi.org/10.1007/978-3-540-85758-7}}, volume = {{5240}}, year = {{2008}}, } @inproceedings{822, author = {{H.

Variations in the characteristics of the load cause change in eigenfrequency and amplitude of the vibration. In most technical applications, this unwanted behaviour is cancelled by the use of control algorithms. However, multiple applications, like bond quality monitoring or chemical and pressure sensors, have found that the load may be characterised by interpreting the change in characteristics of a resonant vibrating device used as a sensor. Surgical resection of tumours is a very difficult task. After localising the tumour by the use of imaging techniques, the resection demands the surgeon to decide where and what to resect based on visual and tactile differentiation of tumour and healthy tissue. Exactness of this process could be enhanced if we can provide the surgeon with a device capable of evaluating mechanical characteristics of the tissue much more accurately than the surgeon himself can do. As the mechanical characteristics of tumour and healthy tissue differ but slightly, the task is to design a system with high sensitivity. Therefore, we have developed a resonant actuator-sensor that allows the differentiation among distinct media that have similar mechanical characteristics to tumour and healthy tissue using a piezoelectric bimorph. The design is based on the detection and evaluation of frequency shift and amplitude variation of the fundamental and higher harmonics using one layer for the resonant excitation of vibration and the other one as the sensing element.}}, author = {{Stroop, Ralf and Uribe, David Oliva and Martinez, Melisa Orta and Brökelmann, Michael and Hemsel, Tobias and Wallaschek, Jörg}}, issn = {{1385-3449}}, journal = {{Journal of Electroceramics}}, keywords = {{Piezo ceramics, Bimorph, Tactile sensor, Tumour tissue}}, number = {{3-4}}, pages = {{237--241}}, publisher = {{Springer US}}, title = {{{Tactile tissue characterisation by piezoelectric systems}}}, doi = {{10.1007/s10832-007-9183-6}}, volume = {{20}}, year = {{2008}}, } @article{4317, abstract = {{Phonon-assisted singlet-singlet relaxation in semiconductor quantum dot molecules is studied theoretically.

It is shown that the phonon-assisted tunneling is much faster (down to ∼ 6 ps even at zero temperature) in comparison with other decoherence processes. The influence of Coulomb interaction is discussed and its consequences are indicated.
