However, run-time reconfigurable systems are more complex to implement than static only systems. This increases time to market, and introduces run-time overhead into the system. Our research aims to raise the abstraction level to develop run-time reconfigurable systems. We present operating system extensions which enable seamless integration of run-time reconfigurable hardware threads into applications. To improve resource utilization, the hardware threads are placed on a fine granularity tile grid. We take advantage of a relocatable module placer targeting modern FPGA to manage the reconfigurable area. The module placer accurately models the FPGA resources to compute feasible placement locations for the hardware threads at run-time. Finally, we evaluate our work by means of a case study that consists of a synthetic application to validate the functionality and performance of the implementation. The results show a reduction in reconfiguration time of up to 42% and more than double resource utilization.","lang":"eng"}],"project":[{"name":"SFB 901","_id":"1"},{"_id":"14","name":"SFB 901 - Subprojekt C2"},{"name":"SFB 901 - Project Area C","_id":"4"}],"file_date_updated":"2018-03-20T07:15:59Z","_id":"374","date_updated":"2022-01-06T06:59:32Z","date_created":"2017-10-17T12:42:05Z","status":"public","year":"2014","citation":{"mla":"Wold, Alexander, et al. “Relocatable Hardware Threads in Run-Time Reconfigurable Systems.” <i>Proceedings of the 10th International Symposium on Reconfigurable Computing: Architectures, Tools, and Applications</i>, edited by Diana Goehringer et al., 2014, pp. 61–72, doi:<a href=\"https://doi.org/10.1007/978-3-319-05960-0_6\">10.1007/978-3-319-05960-0_6</a>.","bibtex":"@inproceedings{Wold_Agne_Torresen_2014, series={LNCS}, title={Relocatable Hardware Threads in Run-Time Reconfigurable Systems}, DOI={<a href=\"https://doi.org/10.1007/978-3-319-05960-0_6\">10.1007/978-3-319-05960-0_6</a>}, booktitle={Proceedings of the 10th International Symposium on Reconfigurable Computing: Architectures, Tools, and Applications}, author={Wold, Alexander and Agne, Andreas and Torresen, Jim}, editor={Goehringer, Diana and Santambrogio, MarcoDomenico and Cardoso, JoãoM.P. and Bertels, KoenEditors}, year={2014}, pages={61–72}, collection={LNCS} }","short":"A.

However, this documentation is often outdated, unavailable, or at least not available as a formal model which analysis tools could use. Reverse engineering methods try to fill this gap. However, as they process the system’s source code, they are easily misled by design deficiencies (e.g., violations of component encapsulation) which leaked into the code during the system’s evolution. Despite the high impact of design deficiencies on the quality of the resulting software architecture models, none of the surveyed related works is able to cope with them during the reverse engineering process. Therefore, we have developed the Archimetrix approach which semi-automatically recovers the system’s concrete architecture in a formal model while simultaneously detecting and removing design deficiencies. We have validated Archi metrix on a case-study system and two implementation variants of the CoCoME benchmark system. Results show that the removal of relevant design deficiencies leads to an architecture model which more closely matches the system’s conceptual architecture."}],"has_accepted_license":"1","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt B1","_id":"9"},{"name":"SFB 901 - Project Area B","_id":"3"}]},{"department":[{"_id":"75"}],"user_id":"477","citation":{"apa":"Herlich, M.

To reduce the energy consumption of RANs different techniques have been proposed. One of the most promising techniques is the use of a low-power sleep mode. However, a sleep mode can also reduce the performance. In this dissertation, I quantify how much energy can be conserved with a sleep mode and which negative effects it has on the performance of RANs. Additionally, I analyze how a sleep mode can be enabled more often and how the performance can be kept high. First, I quantify the effect of power-cycle durations on energy consumption and latency in an abstract queuing system. This results in a trade-off between energy consumption and latency for a single base station (BS). Second, I show that considering a network as a whole (instead of each BS individually) allows the energy consumption to be reduced even further. After these analyses, which are not specific for RANs, I study RANs for the rest of the dissertation. RANs need to both detect and execute the requests of users. Because detection and execution of requests have different requirements, I analyze them independently. I quantify how the number of active BSs can be reduced if the detection ranges of BSs are increased by cooperative transmissions. Next, I analyze how more BSs can be deactivated if the remaining active BSs cooperate to transmit data to the users. However, in addition to increasing the range, cooperative transmissions also radiate more power. This results in higher interference for other users which slows their transmissions down and, thus, increases energy consumption. Therefore, I describe how the radiated power of cooperative transmissions can be reduced if instantaneous channel knowledge is available. Because the implementation in real hardware is impractical for demonstration purposes, I show the results of a simulation that incorporates all effects I studied analytically earlier. In conclusion, I show that a sleep mode can reduce the energy consumption of RANs if applied correctly. To apply a sleep mode correctly, it is necessary to consider power-cycle durations, power profiles, and the interaction of BSs. When this knowledge is combined the energy consumption of RANs can be reduced with only a slight loss of performance. Because this results in a trade-off between energy consumption and performance, each RAN operator has to decide which trade-off is preferred."}],"has_accepted_license":"1","project":[{"name":"SFB 901","_id":"1"},{"name":"SFB 901 - Subprojekt A2","_id":"6"},{"_id":"2","name":"SFB 901 - Project Area A"}],"author":[{"first_name":"Matthias","full_name":"Herlich, Matthias","last_name":"Herlich"}],"file":[{"success":1,"date_updated":"2018-03-20T07:14:52Z","relation":"main_file","date_created":"2018-03-20T07:14:52Z","file_id":"1398","content_type":"application/pdf","access_level":"closed","file_size":1476366,"file_name":"376-Herlich-Dissertation.pdf","creator":"florida"}],"title":"Reducing Energy Consumption of Radio Access Networks","date_updated":"2022-01-06T06:59:35Z","file_date_updated":"2018-03-20T07:14:52Z","_id":"376","status":"public","year":"2014","type":"dissertation","publisher":"Universität Paderborn","ddc":["040"],"date_created":"2017-10-17T12:42:05Z"},{"user_id":"477","file":[{"relation":"main_file","date_updated":"2018-03-20T07:13:36Z","success":1,"creator":"florida","file_size":310961,"file_name":"378-re-chord_journal.pdf","content_type":"application/pdf","file_id":"1396","access_level":"closed","date_created":"2018-03-20T07:13:36Z"}],"title":"Re-Chord: A Self-stabilizing Chord Overlay Network","has_accepted_license":"1","abstract":[{"lang":"eng","text":"The Chord peer-to-peer system is considered, together with CAN, Tapestry and Pastry, as one of the pioneering works on peer-to-peer distributed hash tables (DHT) that inspired a large volume of papers and projects on DHTs as well as peer-to-peer systems in general. Chord, in particular, has been studied thoroughly, and many variants of Chord have been presented that optimize various criteria. Also, several implementations of Chord are available on various platforms. Though Chord is known to be very efficient and scalable and it can handle churn quite well, no protocol is known yet that guarantees that Chord is self-stabilizing, i.e., the Chord network can be recovered from any initial state in which the network is still weakly connected. This is not too surprising since it is known that the Chord network is not locally checkable for its current topology. We present a slight extension of the Chord network, called Re-Chord (reactive Chord), that turns out to be locally checkable, and we present a self-stabilizing distributed protocol for it that can recover the Re-Chord network from any initial state, in which the n peers are weakly connected, in O(nlogn) communication rounds. We also show that our protocol allows a new peer to join or an old peer to leave an already stable Re-Chord network so that within O(logn)^2) communication rounds the Re-Chord network is stable again."}],"doi":"10.1007/s00224-012-9431-2","project":[{"_id":"1","name":"SFB 901"},{"_id":"5","name":"SFB 901 - Subprojekt A1"},{"name":"SFB 901 - Project Area C","_id":"4"},{"name":"SFB 901 - Subproject C1","_id":"13"},{"_id":"2","name":"SFB 901 - Project Area A"}],"page":"591-612","issue":"3","publication":"Theory of Computing Systems","ddc":["040"],"type":"journal_article","citation":{"short":"S.

Each node v can buy a set of edges, each for a fixed price α > 0. Its goal is to minimize its private costs, i.e., the sum (SUM-game, Fabrikant et al., PODC 2003) or maximum (MAX-game, Demaine et al., PODC 2007) of distances from v to all other nodes plus the prices of the bought edges. The above papers show the existence of Nash equilibria as well as upper and lower bounds for the prices of anarchy and stability. In several subsequent papers, these bounds were improved for a wide range of prices α. In this paper, we extend these models by incorporating quality-of-service aspects: Each edge cannot only be bought at a fixed quality (edge length one) for a fixed price α. Instead, we assume that quality levels (i.e., edge lengths) are varying in a fixed interval [βˇ,β^] , 0 series = {LNCS}","lang":"eng"}],"doi":"10.1007/978-3-319-13129-0_34","title":"Quality of Service in Network Creation Games","file":[{"date_created":"2018-03-20T07:05:59Z","access_level":"closed","content_type":"application/pdf","file_id":"1394","file_size":166640,"file_name":"380-WINE2014.pdf","creator":"florida","success":1,"date_updated":"2018-03-20T07:05:59Z","relation":"main_file"}],"author":[{"last_name":"Cord-Landwehr","full_name":"Cord-Landwehr, Andreas","first_name":"Andreas"},{"first_name":"Alexander","full_name":"Mäcker, Alexander","last_name":"Mäcker","id":"13536"},{"first_name":"Friedhelm","full_name":"Meyer auf der Heide, Friedhelm","last_name":"Meyer auf der Heide","id":"15523"}],"date_updated":"2022-01-06T06:59:36Z","page":"423-428","_id":"380","file_date_updated":"2018-03-20T07:05:59Z","type":"conference","year":"2014","status":"public","ddc":["040"],"publication":"Proceedings of the 10th International Conference on Web and Internet Economics (WINE)","date_created":"2017-10-17T12:42:06Z"},{"author":[{"last_name":"Brüseke","first_name":"Frank","full_name":"Brüseke, Frank"},{"full_name":"Wachsmuth, Henning","first_name":"Henning","last_name":"Wachsmuth","id":"3900"},{"last_name":"Engels","full_name":"Engels, Gregor","first_name":"Gregor"},{"full_name":"Becker, Steffen","first_name":"Steffen","last_name":"Becker"}],"title":"PBlaman: performance blame analysis based on Palladio contracts","department":[{"_id":"600"}],"user_id":"82920","citation":{"chicago":"Brüseke, Frank, Henning Wachsmuth, Gregor Engels, and Steffen Becker. “PBlaman: Performance Blame Analysis Based on Palladio Contracts.” In <i>Proceedings of the 4th International Symposium on Autonomous Minirobots for Research and Edutainment</i>, 1975–2004, 2014.","ieee":"F.

We investigate a duopoly of providers and analyze stable market prices in two-part tariffs. Further, we study offers that allow a specified amount of included usage (three-part tariffs).

Depending on the type of safety property, proofs can however become quite large and their validation - though faster than their construction - still time consuming. In this paper we introduce a new concept for safe execution of untrusted code. It keeps the idea of putting the time consuming part of proving on the side of the code producer, however, attaches no proofs to code anymore but instead uses the proof to transform the program into an equivalent but more efficiently verifiable program. Code consumers thus still do proving themselves, however, on a computationally inexpensive level only.

These reputation values, typically aggregations of individual user ratings, shall be reliable, i.e. should enable a realistic assessment of the probability that the rated party behaves as expected in a transaction. In order for the reputation values to stay reliable and, thus, for the reputation system to provide a benefit, the system needs to be resistant against manipulations by users, the rated parties trying to improve their reputation values, and even against competitors trying to worsen a reputation value. At the same time, a reputation system shall provide privacy protection for users: rated parties shall not be able to learn who provided a certain rating. Otherwise users might not take part in the system as they fear bad feedback in revenge for bad ratings, or users do not want to be connected to certain transactions based on their provided ratings. In this paper we come up with a solution that provides both, reliability of reputation values on the one hand, and privacy protection for users on the other hand. In contrast to related work, our solution only makes use of a single reputation provider that needs to be trusted (to a certain extent) and does not require any bulletin boards to be present in the system.

We consider a wireless network consisting of a set of n honest and reliable nodes within transmission (and interference) range of each other, and we model the external disruptions with a powerful adaptive adversary. This adversary may know the protocol and its entire history and can use this knowledge to jam the wireless channel at will at any time. It is allowed to jam a (1 − )-fraction of the timesteps, for an arbitrary constant > 0 unknown to the nodes. The nodes cannot distinguish between the adversarial jamming or a collision of two or more messages that are sent at the same time. We demonstrate, for the first time, that there is a local-control MAC protocol requiring only very limited knowledge about the adversary and the network that achieves a constant (asymptotically optimal) throughput for the nonjammed time periods under any of the aforementioned adversarial strategies. The derived principles are also useful to build robust applications on top of the MAC layer, and we present an exemplary study for leader election, one of the most fundamental tasks in distributed computing.","lang":"eng"}],"doi":"10.1145/2635818","project":[{"name":"SFB 901","_id":"1"},{"_id":"13","name":"SFB 901 - Subprojekt C1"},{"name":"SFB 901 - Project Area C","_id":"4"}],"issue":"4","ddc":["040"],"publication":"Transactions on Algorithms","type":"journal_article"},{"date_created":"2018-08-11T16:13:24Z","publication":"Proceedings of COLING 2014, the 25th International Conference on Computational Linguistics: Technical Papers","language":[{"iso":"eng"}],"year":"2014","type":"conference","status":"public","_id":"3877","page":"553-564","date_updated":"2022-01-06T06:59:47Z","title":"Modeling Review Argumentation for Robust Sentiment Analysis","author":[{"first_name":"Henning","full_name":"Wachsmuth, Henning","id":"3900","last_name":"Wachsmuth"},{"full_name":"Trenkmann, Martin","first_name":"Martin","last_name":"Trenkmann"},{"first_name":"Benno","full_name":"Stein, Benno","last_name":"Stein"},{"last_name":"Engels","first_name":"Gregor","full_name":"Engels, Gregor"}],"citation":{"short":"H.

Confronted with model and data integration tasks for distributed Decision Support Systems which are especially composed out of software services, we describe model constituents such as constraints both structurally and semantically. Within our approach, typed model constituents can be integrated into complete models and the instantiation of model constituents itself with data and data models can be wrapped into semantic software services. Besides others, this supports the automated generation of adaptors and the search for and composition of services. The basic idea of our approach is to represent the optimization models as instance knowledge of different ontologies for both optimization and application domains. By separating the model expression structure from the goal and constraint conceptualizations predefined modeling constructs can be reused, where we do not only separate the model structure from data, but can also abstract the structure from a specific data model. We present an XML and ontology-query based approach for this separation and demonstrate the resulting flexible model integration procedure out of reusable goal and constraint types on a network flow problem."}],"title":"Ontology-based Representation of Optimization Models","file":[{"success":1,"date_updated":"2018-03-20T07:01:29Z","relation":"main_file","access_level":"closed","file_id":"1386","content_type":"application/pdf","date_created":"2018-03-20T07:01:29Z","creator":"florida","file_name":"389-201x_-_Stapel__Suhl_-_Ontology-based_Representation_of_Optimization_Models.pdf","file_size":595852}],"author":[{"last_name":"Stapel","first_name":"Florian","full_name":"Stapel, Florian"},{"last_name":"Suhl","first_name":"Lena","full_name":"Suhl, Lena"}],"citation":{"short":"F.

Based on a customer-specific request, available service offers have to be discovered and composed into sophisticated IT services that fulfill the customer's request.A prerequisite of this vision are rich service descriptions, which comprise structural as well as behavioral aspects of the services, otherwise an accurate service discovery and composition is not possible. However, automatic matching of service requests and offers specified in rich service descriptions for the purpose of service discovery is a complex task, due to the multifaceted heterogeneity of the service partners. This heterogeneity includes the use of different specification languages, different underlying ontologies, or different levels of granularity in the specification itself.In this article, we present a comprehensive approach for service discovery and composition, which overcomes the underlying heterogeneity of the service partners. Based on a realistic case study of our industrial partner from the e-tourism domain, we first introduce an automatic matching mechanism for service requests and offers specified in a rich service description language. In addition, we propose an automatic service composition approach, which determines possible service compositions by composing the service protocols through a composition strategy based on labeled transition systems.
