On the negative side, we show that combinatorially Voronoi cells for arbitrary strictly convex and smooth norms are much more complicated than in the Euclidean case.In particular, we construct a family of three-dimensional lattices whose number of Voronoi-relevant vectors with respect to the l_3-norm is unbounded.Since the algorithm of Micciancio and Voulgaris and its run time analysis crucially dependonthefactthatfortheEuclidean normthenumber of Voronoi-relevant vectors is single exponential in the lattice dimension, this indicates that the techniques of Micciancio and Voulgaris cannot be extended to achieve deterministic single exponential time algorithms for lattice problems with respect to arbitrary l_p-norms.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"http://arxiv.org/pdf/1512.00720v1.pdf"}],"date_updated":"2022-01-06T06:55:49Z","title":"Voronoi Cells of Lattices with Respect to Arbitrary Norms","year":"2015","author":[{"id":"23","last_name":"Blömer","first_name":"Johannes","full_name":"Blömer, Johannes"},{"full_name":"Kohn, Kathlén","last_name":"Kohn","first_name":"Kathlén"}],"oa":"1","project":[{"_id":"1","name":"SFB 901"},{"name":"SFB 901 - Subprojekt C1","_id":"13"},{"name":"SFB 901 - Project Area C","_id":"4"}],"file_date_updated":"2018-03-21T10:30:18Z","citation":{"chicago":"Blömer, Johannes, and Kathlén Kohn. <i>Voronoi Cells of Lattices with Respect to Arbitrary Norms</i>.

Since many scheduling problems are NP-hard in the strong sense, there is a need for developing solution heuristics. For scheduling problems with setup times on unrelated parallel machines, there is limited research on solution methods and to the best of our knowledge, parallel computer architectures have not yet been taken advantage of. We address this gap by proposing and implementing a new solution heuristic and by testing different parallelization strategies. In our computational experiments, we show that our heuristic calculates near-optimal solutions even for large instances and that computing time can be reduced substantially by our parallelization approach."}],"language":[{"iso":"eng"}],"author":[{"full_name":"Rauchecker, Gerhard","last_name":"Rauchecker","first_name":"Gerhard"},{"last_name":"Schryen","first_name":"Guido","full_name":"Schryen, Guido","id":"72850"}],"year":"2015","title":"High-Performance Computing for Scheduling Decision Support: A Parallel Depth-First Search Heuristic","date_updated":"2022-01-06T07:02:30Z","oa":"1","citation":{"apa":"Rauchecker, G., &#38; Schryen, G.

It allows customers to easily scale their infrastructure and save on the overall cost of operation. However Cloud service offerings can only thrive if customers are satisfied with service performance. Allow-ing instantaneous access and flexible scaling while maintaining the service levels and offering competitive prices poses a significant challenge to Cloud Computing providers. Furthermore services will remain available in the long run only if this business generates a stable revenue stream. To address these challenges we introduce novel policy-based service admission control mod-els that aim at maximizing the revenue of Cloud providers while taking in-formational uncertainty regarding resource requirements into account. Our evaluation shows that policy-based approaches statistically significantly out-perform first come first serve approaches, which are still state of the art. Furthermore the results give insights in how and to what extent uncertainty has a negative impact on revenue.","lang":"eng"}],"extern":"1","issue":"2","publication":"European Journal of Operational Research","language":[{"iso":"eng"}],"intvolume":"       244","date_updated":"2022-01-06T07:02:30Z","author":[{"last_name":"Püschel","first_name":"Tim","full_name":"Püschel, Tim"},{"id":"72850","last_name":"Schryen","first_name":"Guido","full_name":"Schryen, Guido"},{"full_name":"Hristova, Diana","last_name":"Hristova","first_name":"Diana"},{"last_name":"Neumann","first_name":"Dirk","full_name":"Neumann, Dirk"}],"title":"Revenue Management for Cloud Computing Providers: Decision Models for Service Admission Control under Non-probabilistic Uncertainty","year":"2015"},{"date_created":"2017-11-27T10:22:25Z","department":[{"_id":"75"}],"oa":"1","type":"preprint","citation":{"bibtex":"@article{Dräxler_Karl_2015, title={Specification of Complex Structures in Distributed Service Function Chaining Using a YANG Data Model}, journal={CoRR}, author={Dräxler, Sevil and Karl, Holger}, year={2015} }","ama":"Dräxler S, Karl H.

While research on IT security investment is fast growing, it lacks a theoretical basis for structuring research, explaining economic-technological phenomena and guide future research. We address this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical perspective adopt-ing the Resource-Based View and the Organizational Learning Theory. The joint appli-cation of these theories allows to conceptualize in one theoretical model the organiza-tional learning effects that occur when the protection of organizational resources through IT security countermeasures develops over time. We use this model of IT security invest-ments to synthesize findings of a large body of literature and to derive research gaps. We also discuss managerial implications of (closing) these gaps by providing practical ex-amples.","lang":"eng"}],"extern":"1","publication":"International Conference on Information Systems","keyword":["Information Security","Investment","Literature review","Resource-based View","Organi-zational Learning Theory","Multi-theoretical Perspective"],"type":"conference","department":[{"_id":"277"}],"file":[{"file_name":"ICIS PROCEEDINGS PAPER - Security Investments.pdf","access_level":"open_access","file_size":958019,"relation":"main_file","date_updated":"2018-12-13T15:09:32Z","file_id":"6038","content_type":"application/pdf","creator":"hsiemes","date_created":"2018-12-07T11:45:31Z"}],"date_created":"2018-11-14T11:25:38Z"},{"file_date_updated":"2018-12-13T15:09:01Z","publication":"23rd European Conference on Information Systems (ECIS 2015)","citation":{"apa":"Weishäupl, E., Yasasin, E., &#38; Schryen, G.

However, it is a challenging task to assign access rights to employees? accounts within a satisfying time frame. In addition, the management of multiple accounts and identities can be very onerous and time consuming for the responsible administrator and therefore expensive for the organization. In order to meet these challenges, firms decide to invest in introducing an Identity and Access Management System (IAMS) that supports the organization by using policies to assign permissions to accounts, groups, and roles. In practice, since various versions of IAMSs exist, it is a challenging task to decide upon introduction of an IAMS. The following study proposes a first attempt of a decision support model for practitioners which considers four alternatives: Introduction of an IAMS with Role-based Access Control RBAC) or without and no introduction of IAMS again with or without RBAC. To underpin the practical applicability of the proposed model, we parametrize and operationalize it based on a real world use case using input from an expert interview.","lang":"eng"}],"extern":"1","language":[{"iso":"eng"}],"author":[{"full_name":"Weishäupl, Eva","first_name":"Eva","last_name":"Weishäupl"},{"full_name":"Kunz, Michael","first_name":"Michael","last_name":"Kunz"},{"last_name":"Yasasin","first_name":"Emrah","full_name":"Yasasin, Emrah"},{"full_name":"Wagner, Gerit","first_name":"Gerit","last_name":"Wagner"},{"last_name":"Prester","first_name":"Julian","full_name":"Prester, Julian"},{"id":"72850","first_name":"Guido","last_name":"Schryen","full_name":"Schryen, Guido"},{"last_name":"Pernul","first_name":"Günther","full_name":"Pernul, Günther"}],"title":"Towards an Economic Approach to Identity and Access Management Systems Using Decision Theory","year":"2015","date_updated":"2022-01-06T07:02:04Z"},{"date_updated":"2022-01-06T07:02:09Z","author":[{"last_name":"Schryen","first_name":"Guido","full_name":"Schryen, Guido","id":"72850"},{"full_name":"Weishäupl, Eva","first_name":"Eva","last_name":"Weishäupl"}],"year":"2015","title":"IT-Sicherheit: Ökonomisch Planen und Bewerten","language":[{"iso":"eng"}],"extern":"1","publication":"Managementkompass","issue":"2","department":[{"_id":"277"}],"type":"journal_article","date_created":"2018-11-14T13:59:53Z","file":[{"file_size":101976,"access_level":"open_access","file_name":"MK-DigitalSecurity-2015_Schryen.pdf","date_updated":"2018-12-13T15:09:42Z","relation":"main_file","content_type":"application/pdf","file_id":"6039","creator":"hsiemes","date_created":"2018-12-07T11:46:04Z"}],"has_accepted_license":"1","status":"public","ddc":["000"],"user_id":"61579","publisher":"Frankfurt Business Media, Der F.A.Z.-Fachverlag","_id":"5616","page":"17-18","citation":{"ieee":"G.

Yet, we observe a lack of theoretical underpinning of and epistemological insights into how literature reviews can contribute to knowledge creation and have actually contributed in the IS discipline. To address these theoretical and empirical research gaps, we suggest a novel epistemological model of literature reviews. This model allows us to align different contributions of literature reviews with their underlying knowledge conversions - thereby building a bridge between the previously largely unconnected fields of literature reviews and epistemology. We evaluate the appropriateness of the model by conducting an empirical analysis of 173 IS literature reviews which were published in 39 pertinent IS journals between 2000 and 2014. Based on this analysis, we derive an epistemological taxonomy of IS literature reviews, which complements previously suggested typologies."}],"extern":"1","date_created":"2018-11-14T14:01:13Z","file":[{"creator":"hsiemes","date_created":"2018-12-07T11:44:48Z","relation":"main_file","date_updated":"2018-12-13T15:09:22Z","file_name":"ICIS PROCEEDINGS PAPER - Literature Reviews.pdf","access_level":"open_access","file_size":487102,"file_id":"6037","content_type":"application/pdf"}],"department":[{"_id":"277"}],"keyword":["Literature review","Research methods/methodology","Theory of knowledge"],"type":"conference","status":"public","has_accepted_license":"1","_id":"5618","ddc":["000"],"user_id":"61579","citation":{"bibtex":"@inproceedings{Schryen_Wagner_Benlian_2015, title={Theory of Knowledge for Literature Reviews: An Epistemological Model, Taxonomy and Empirical Analysis of IS Literature}, booktitle={International Conference on Information Systems (ICIS)}, author={Schryen, Guido and Wagner, Gerit and Benlian, Alexander}, year={2015} }","ama":"Schryen G, Wagner G, Benlian A.

MLNs combine graphical models with first-order logic. They areparticularly suitable for providing inference in the presence of inconsistent and incomplete data, which are typical of an automatic speech recognizer's (ASR) output in the presence of degraded speech. The target application is a speech interface to a home automation system to be operated by people with speech impairments, where the ASR output is particularly noisy. In order to cater for dysarthric speech with non-canonical phoneme realizations, acoustic representations of the input speech are learned in an unsupervised fashion. While training data transcripts are not required for the acoustic model training, the MLN training requires supervision, however, at a rather loose and abstract level. Results on two databases, one of them for dysarthric speech, show that MLN-based semantic analysis clearly outperforms baseline approaches employing non-negative matrix factorization, multinomial naive Bayes models, or support vector machines.","lang":"eng"}],"publication":"INTERSPEECH 2015","citation":{"ieee":"V.

A thorough simulative evaluation yields insight into parameter selection and provides details on the performance for both directional and omni-directional microphones. A comparison to the well known Steered Response Power with Phase Transform (SRP-PHAT) algorithm and a state of the art DoA estimator which explicitly accounts for aliasing, shows in particular the advantages of presented algorithm if inter-sensor level differences are indicative of the DoA, as with directional microphones."}],"related_material":{"link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2015/DrJaHa15_Presentation.pdf","relation":"supplementary_material","description":"Presentation"}]},"citation":{"mla":"Drude, Lukas, et al. “DOA-Estimation Based on a Complex Watson Kernel Method.” <i>23th European Signal Processing Conference (EUSIPCO 2015)</i>, 2015.","ama":"Drude L, Jacob F, Haeb-Umbach R.

The first can be adjusted to different conditions by an appropriate parameter setting, while the latter needs to be trained on conditions similar to the ones expected at decoding time, making it vulnerable to a mismatch between training and test conditions. We use a DNN backend and study reverberant ASR under three types of mismatch conditions: different room reverberation times, different speaker to microphone distances and the difference between artificially reverberated data and the recordings in a reverberant environment. We show that for these mismatch conditions BFE can provide the targets for a DA. This unsupervised adaptation provides a performance gain over the direct use of BFE and even enables to compensate for the mismatch of real and simulated reverberant data."}],"date_created":"2019-07-12T05:28:45Z","keyword":["codecs","signal denoising","speech recognition","Bayesian feature enhancement","denoising autoencoder","reverberant ASR","single-channel speech recognition","speaker to microphone distances","unsupervised adaptation","Adaptation models","Noise reduction","Reverberation","Speech","Speech recognition","Training","deep neuronal networks","denoising autoencoder","feature enhancement","robust speech recognition"],"type":"conference","oa":"1","department":[{"_id":"54"}]}]
