We consider the classical graph coloring problem and investigate the dynamic setting where edges are added to the current graph. We then analyze the expected time for randomized search heuristics to recompute high quality solutions. This includes the (1+1) EA and RLS in a setting where the number of colors is bounded and we are minimizing the number of conflicts as well as iterated local search algorithms that use an unbounded color palette and aim to use the smallest colors and - as a consequence - the smallest number of colors. We identify classes of bipartite graphs where reoptimization is as hard as or even harder than optimization from scratch, i. e. starting with a random initialization. Even adding a single edge can lead to hard symmetry problems. However, graph classes that are hard for one algorithm turn out to be easy for others. In most cases our bounds show that reoptimization is faster than optimizing from scratch. Furthermore, we show how to speed up computations by using problem specific operators concentrating on parts of the graph where changes have occurred.","lang":"eng"}],"date_created":"2023-11-14T15:58:52Z","publisher":"Association for Computing Machinery","title":"Runtime Analysis of Randomized Search Heuristics for Dynamic Graph Coloring","year":"2019","department":[{"_id":"819"}],"series_title":"GECCO ’19","user_id":"102979","_id":"48843","extern":"1","type":"conference","status":"public","author":[{"first_name":"Jakob","orcid":"0000-0002-4121-4668","last_name":"Bossek","id":"102979","full_name":"Bossek, Jakob"},{"first_name":"Frank","full_name":"Neumann, Frank","last_name":"Neumann"},{"first_name":"Pan","full_name":"Peng, Pan","last_name":"Peng"},{"full_name":"Sudholt, Dirk","last_name":"Sudholt","first_name":"Dirk"}],"date_updated":"2023-12-13T10:42:37Z","doi":"10.1145/3321707.3321792","publication_identifier":{"isbn":["978-1-4503-6111-8"]},"publication_status":"published","page":"1443–1451","citation":{"ieee":"J.

Particle pollution is known as a serious threat to human health. Along with developments in the use of wireless sensors and the IoT, we propose an architecture that flexibly measures and processes stream data collected in real-time by movable and low-cost IoT sensors. Thus, it enables a wide-spread network of wireless sensors that can follow changes in human behavior. Apart from stating reasons for the need of such a development and its requirements, we provide a conceptual design as well as a technological design of such an architecture. The technological design consists of Kaa and Apache Storm which can collect air pollution information in real-time and solve various problems to process data such as missing data and synchronization. This enables us to add a simulation in which we provide issues that might come up when having our architecture in use. Together with these issues, we state r easons for choosing specific modules among candidates. Our architecture combines wireless sensors with the Kaa IoT framework, an Apache Kafka pipeline and an Apache Storm Data Stream Management System among others. We even provide open-government data sets that are freely available.","lang":"eng"}],"publication":"Proceedings of the 2nd International Conference on Internet of Things, Big Data and Security","doi":"10.5220/0006354801170124","conference":{"name":"2nd International Conference on Internet of Things, Big Data and Security (IoTBDS 2017)","start_date":"2017-04-24","end_date":"2017-04-26","location":"Porto, Portugal"},"author":[{"id":"58701","full_name":"Kersting, Joschka","last_name":"Kersting","first_name":"Joschka"},{"first_name":"Michaela","full_name":"Geierhos, Michaela","id":"42496","orcid":"0000-0002-8180-5606","last_name":"Geierhos"},{"full_name":"Jung, Hanmin","last_name":"Jung","first_name":"Hanmin"},{"full_name":"Kim, Taehong","last_name":"Kim","first_name":"Taehong"}],"date_updated":"2022-01-06T06:51:03Z","page":"117-124","citation":{"chicago":"Kersting, Joschka, Michaela Geierhos, Hanmin Jung, and Taehong Kim. “Internet of Things Architecture for Handling Stream Air Pollution Data.” In <i>Proceedings of the 2nd International Conference on Internet of Things, Big Data and Security</i>, edited by Muthu Ramachandran, Víctor Méndez Muñoz, Verena Kantere, Gary Wills, Robert Walters, and Victor Chang, 117–24.

Their coupling to the crystal environment manifests itself in a limitation of the spin coherence times to the microsecond range, both for electron and hole spins. This rather short-lived coherence compared to atomic states asks for manipulations on timescales as short as possible. Due to the huge dipole moment for transitions between the valence and conduction band, pulsed laser systems offer the possibility to perform manipulations within picoseconds or even faster. Here, we report on results that show the potential of optical spin manipulations with currently available pulsed laser systems. Using picosecond laser pulses, we demonstrate optically induced spin rotations of electron and hole spins. We further realize the optical decoupling of the hole spins from the nuclear surrounding at the nanosecond timescales and demonstrate an all-optical spin tomography for interacting electron spin sub-ensembles.","lang":"eng"}],"keyword":["Spin Polarization","Pump Pulse","Trion","Spin Component","Coherence Time"],"language":[{"iso":"eng"}],"publication_identifier":{"issn":["0946-2171","1432-0649"]},"publication_status":"published","intvolume":"       122","citation":{"ieee":"S.

Especially technology-based self-service channels have found their way into the 21st century service economy. While research embraces these channels for their cost-efficiency, it has not examined whether a shift from personal to self-service affects customer–firm relationships. Drawing from the service-dominant logic and its central concept of value-in-context, we discuss customers’ value creation in self-service and personal service channels and examine the long-term impact of these channels on customer retention. Using longitudinal customer data, we investigate how the ratio of self-service versus personal service use influences customer defection over time. Our findings suggest that the ratio of self-service to personal service used affects customer defection in a U-shaped manner, with intermediate levels of both self-service and personal service use being associated with the lowest likelihood of defection. We also find that this effect mitigates over time. We conclude that firms should not shift customers toward self-service channels completely, especially not at the beginning of a relationship. Our study underlines the importance of understanding when and how self-service technologies create valuable customer experiences and stresses the notion of actively managing customers’ cocreation of value.

Häufig handelt es sich um neue Werkzeuge oder Trends (Klicker, MOOCs, Web 2.0), die einerseits potenzialreich und spannend erscheinen, deren didaktische Verwertbarkeit sich aber nicht auf den ersten Blick erschließt. Oft folgt nach einer euphorischen Erprobung schnell die Ernüchterung, wenn festgestellt wird, dass sich durch die digitalen Technologien allein kein erhöhter Lernerfolg ergibt und auch die Studierenden keine nachhaltigen Motivationsschübe erfahren.\r\nAus der Hochschuldidaktik hört man häufig und berechtigterweise kritische Stimmen, welche die Einbettung digitaler Medien in sorgfältig geplante didaktische Arrangements betonen. Es stellt sich die Frage, inwieweit damit die Kreativität und der Entdeckergeist von Lehrenden und Studierenden eingeschränkt werden. Wir wollen im Disq-Space der Frage nachgehen, wie die Hochschuldidaktik auf neue digitale Trends reagieren und dabei einen Mittelweg zwischen \"kreativem Ausprobieren\" und pädagogisch-didaktischer Rationalität einschlagen kann. Zunächst werden die Ergebnisse einer aktuellen Umfrage an der Universität St. Gallen zu den Vorstellungen Studierender zu innovativer Lehre vorgestellt. Nach einer Öffnung des Raums für gute sowie schlechte Erfahrungen und Bespiele von Seiten der Teilnehmenden soll diskutiert werden, welche personellen, didaktischen und organisatorischen Voraussetzungen erfüllt sein müssen, damit Digitalisierung die Kompetenzentwicklung der Studierenden unterstützt.\r\nDie Ergebnisse der Diskussionsrunde werden im Blog des Teams Hochschulentwicklung zur Verfügung gestellt.

A recently proposed observation model is employed whose time-variant observation error statistics are obtained as a side product of the inference of the a posteriori probability density function of the clean speech feature vectors. Further a reduction of the computational effort and the memory requirements are achieved by using a recursive formulation of the observation model. The performance of the proposed algorithms is first experimentally studied on a connected digits recognition task with artificially created noisy reverberant data. It is shown that the use of the time-variant observation error model leads to a significant error rate reduction at low signal-to-noise ratios compared to a time-invariant model. Further experiments were conducted on a 5000 word task recorded in a reverberant and noisy environment. A significant word error rate reduction was obtained demonstrating the effectiveness of the approach on real-world data.","lang":"eng"}],"status":"public","type":"journal_article","publication":"IEEE Transactions on Audio, Speech, and Language Processing","title":"Bayesian Feature Enhancement for Reverberation and Noise Robust Speech Recognition","doi":"10.1109/TASL.2013.2258013","date_updated":"2022-01-06T06:51:11Z","date_created":"2019-07-12T05:29:42Z","author":[{"full_name":"Leutnant, Volker","last_name":"Leutnant","first_name":"Volker"},{"full_name":"Krueger, Alexander","last_name":"Krueger","first_name":"Alexander"},{"first_name":"Reinhold","id":"242","full_name":"Haeb-Umbach, Reinhold","last_name":"Haeb-Umbach"}],"volume":21,"year":"2013","citation":{"ieee":"V.

Consequently, validation of the power design intent should begin as early as possible at electronic system-level (ESL) together with first executable system specifications for integrity tests. However, today's system-level design methodologies usually focus on the abstraction of digital logic and time, so that typical low-power aspects cannot be considered so far. In this paper, we present a high-level modeling approach on top of the SystemC/TLM standard to simulate power distribution and voltage based implications in a \"loosely-timed\" functional execution context. The approach reuses legacy TLM models and prevents the need for detailed lock-step process synchronization in contrast to existing methods. A case study derived from an open source low-power design demonstrates the efficiency of our approach in terms of simulation performance and testability."}],"author":[{"full_name":"Mischkalla, Fabian","last_name":"Mischkalla","first_name":"Fabian"},{"last_name":"Müller","id":"16243","full_name":"Müller, Wolfgang","first_name":"Wolfgang"}],"date_created":"2023-01-16T12:08:03Z","date_updated":"2023-01-16T12:08:17Z","publisher":"IEEE","doi":"10.1109/PATMOS.2013.6662171","conference":{"name":"23rd International Workshop on Power and Timing Modeling, Optimization and Simulation (PATMOS)"},"title":"Efficient Power-Intent Validation Using \"Loosely-Timed\" Simulation Models: A Non-Invasive Approach","publication_identifier":{"eisbn":["978-1-4799-1170-7"]},"citation":{"chicago":"Mischkalla, Fabian, and Wolfgang Müller. “Efficient Power-Intent Validation Using ‘Loosely-Timed’ Simulation Models: A Non-Invasive Approach.” Karlsruhe: IEEE, 2013. <a href=\"https://doi.org/10.1109/PATMOS.2013.6662171\">https://doi.org/10.1109/PATMOS.2013.6662171</a>.","ieee":"F.
