We propose two approaches to SAD, where one is based on statistical signal processing, while the other utilizes neural networks. The former employs sophisticated signal processing to track the noise and speech energies and is meant to support the case for a resource efficient, unsupervised signal processing approach.\r\nThe latter introduces a recurrent network layer that operates on short segments of the input speech to do temporal smoothing in the presence of non-stationary noise. The systems are tested on the Fearless Steps challenge database, which consists of the transmission data from the Apollo-11 space mission.\r\nThe statistical SAD  achieves comparable detection performance to earlier proposed neural network based SADs, while the neural network based approach leads to a decision cost function of 1.07% on the evaluation set of the 2020 Fearless Steps Challenge, which sets a new state of the art.","lang":"eng"}],"file":[{"file_name":"ms.pdf","access_level":"closed","file_id":"20697","file_size":998706,"date_created":"2020-12-11T12:33:04Z","creator":"jensheit","date_updated":"2020-12-11T12:33:04Z","relation":"main_file","success":1,"content_type":"application/pdf"}],"status":"public","type":"conference","publication":"INTERSPEECH 2020 Virtual Shanghai China","ddc":["000"],"keyword":["voice activity detection","speech activity detection","neural network","statistical speech processing"],"language":[{"iso":"eng"}],"file_date_updated":"2020-12-11T12:33:04Z","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"20505","user_id":"460","department":[{"_id":"54"}]},{"extern":"1","_id":"17667","department":[{"_id":"63"},{"_id":"541"}],"user_id":"83983","series_title":"2019 6th IEEE International Conference on Cyber Security and Cloud Computing (CSCloud)/ 2019 5th IEEE International Conference on Edge Computing and Scalable Cloud (EdgeCom)","status":"public","type":"conference","doi":"10.1109/CSCloud/EdgeCom.2019.000-9","conference":{"name":"2019 6th IEEE International Conference on Cyber Security and Cloud Computing (CSCloud)/ 2019 5th IEEE International Conference on Edge Computing and Scalable Cloud (EdgeCom)"},"main_file_link":[{"url":"https://ieeexplore.ieee.org/abstract/document/8854057/authors#authors"}],"date_updated":"2022-01-06T06:53:16Z","author":[{"last_name":"Koning","full_name":"Koning, Ralph","first_name":"Ralph"},{"first_name":"Gleb","last_name":"Polevoy","full_name":"Polevoy, Gleb","id":"83983"},{"first_name":"Lydia","last_name":"Meijer","full_name":"Meijer, Lydia"},{"full_name":"de Laat, Cees","last_name":"de Laat","first_name":"Cees"},{"first_name":"Paola","last_name":"Grosso","full_name":"Grosso, Paola"}],"page":"113-123","citation":{"apa":"Koning, R., Polevoy, G., Meijer, L., de Laat, C., &#38; Grosso, P.

In previous work on physician reviews and the corresponding websites, it was observed that there occurs faulty behavior by some reviewers and there were noteworthy differences in the technical implementation of the portals and in the efforts of site operators to maintain high quality reviews.

To put VMs and CNs together, an orchestration framework that can chain services across distributed and heterogeneous domains is required. To this end, we implemented a framework by extending and consolidating state-of-the-art tools and technologies originated from Network Function Virtualization (NFV), Software-defined Networking (SDN) and cloud computing environments.

In this demo we will demonstrate this unique 5GTANGO concept using an elastic proxy service supported by a high availability SLA enforced through a range of traffic regimes.","lang":"eng"}]},{"title":"Measuring the efficiency of SDN mitigations against attacks on computer infrastructures","doi":"https://doi.org/10.1016/j.future.2018.08.011","date_updated":"2022-01-06T06:53:16Z","date_created":"2020-08-06T15:23:11Z","author":[{"last_name":"Koning","full_name":"Koning, R.","first_name":"R."},{"last_name":"de Graaff","full_name":"de Graaff, B.","first_name":"B."},{"first_name":"Gleb","last_name":"Polevoy","full_name":"Polevoy, Gleb","id":"83983"},{"first_name":"R.","last_name":"Meijer","full_name":"Meijer, R."},{"last_name":"de Laat","full_name":"de Laat, C.","first_name":"C."},{"last_name":"Grosso","full_name":"Grosso, P.","first_name":"P."}],"year":"2018","citation":{"ama":"Koning R, de Graaff B, Polevoy G, Meijer R, de Laat C, Grosso P.

In a SARNET, an agent running a control loop constantly assesses the security state of the network by means of observables. The agent reacts to and resolves security problems, while learning from its previous decisions. Two main metrics govern the decision process in a SARNET: impact and efficiency; these metrics can be used to compare and evaluate countermeasures and are the building blocks for self-learning SARNETs that exhibit autonomous response. In this paper we present the software implementation of the SARNET framework, evaluate it in a real-life network and discuss the tradeoffs between parameters used by the SARNET agent and the efficiency of its actions."}],"status":"public","publication":"Future Generation Computer Systems","type":"journal_article"},{"author":[{"first_name":"Joschka","id":"58701","full_name":"Kersting, Joschka","last_name":"Kersting"},{"full_name":"Geierhos, Michaela","id":"42496","orcid":"0000-0002-8180-5606","last_name":"Geierhos","first_name":"Michaela"},{"full_name":"Jung, Hanmin","last_name":"Jung","first_name":"Hanmin"},{"last_name":"Kim","full_name":"Kim, Taehong","first_name":"Taehong"}],"date_updated":"2022-01-06T06:51:03Z","doi":"10.5220/0006354801170124","conference":{"start_date":"2017-04-24","name":"2nd International Conference on Internet of Things, Big Data and Security (IoTBDS 2017)","location":"Porto, Portugal","end_date":"2017-04-26"},"has_accepted_license":"1","publication_identifier":{"isbn":["978-989-758-245-5"]},"publication_status":"published","page":"117-124","citation":{"ama":"Kersting J, Geierhos M, Jung H, Kim T.

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.

This autonomous behavior adaptation is made possible by software in combination with complex sensor and actuator systems and by sophisticated information processing, all of which make these systems increasingly complex. This increasing complexity makes the design process a challenging task and brings new complex possibilities for operation and maintenance. However, with the risk of increased system complexity also comes the chance to adapt system behavior based on current reliability, which in turn increases reliability. The development of such an adaption strategy requires appropriate methods to evaluate reliability based on currently selected system behavior. A common approach to implement such adaptivity is to base system behavior on different working points that are obtained using multiobjective optimization. During operation, selection among these allows a changed operating strategy. To allow for multiobjective optimization, an accurate system model including system reliability is required. This model is repeatedly evaluated by the optimization algorithm. At present, modeling of system reliability and synchronization of the models of behavior and reliability is a laborious manual task and thus very error-prone. Since system behavior is crucial for system reliability, an integrated model is introduced that integrates system behavior and system reliability. The proposed approach is used to formulate reliability-related objective functions for a clutch test rig that are used to compute feasible working points using multiobjective optimization.","lang":"eng"}],"status":"public","date_updated":"2019-09-16T10:20:49Z","author":[{"id":"14802","full_name":"Kaul, Thorben","last_name":"Kaul","first_name":"Thorben"},{"full_name":"Meyer, Tobias","last_name":"Meyer","first_name":"Tobias"},{"last_name":"Sextro","id":"21220","full_name":"Sextro, Walter","first_name":"Walter"}],"date_created":"2019-05-27T09:37:46Z","volume":"Vol. 231(4)","title":"Formulation of reliability-related objective functions for design of intelligent mechatronic systems","doi":"10.1177/1748006X17709376","quality_controlled":"1","year":"2017","citation":{"ieee":"T.

In comparison to real life human interaction, in which sentiments have been shown to have an influence on human behaviour, it is not yet completely understood which mechanisms explain how sentiments influence users in online environments. We develop a theoretical framework that tries to bridge the gap between social influence theories that focus on offline interactions on one hand and online interaction in social networks on the other hand. We then test our hypothesis about the influence and dissemination of sentiments in a quantitative analysis that is based on retrieved textual messages of communication patterns in over 12000 online social networks. Our empirical results suggest a general influence of sentiments on node communication patterns that is evidenced by increased occurrences of subsequent messages that express the same sentiment polarization. We interpret these findings and suggest future research to advance our currently limited theories that assume perceived and generalized social influence to path-dependent social influence models that consider actual behaviour.","lang":"eng"}],"status":"public","type":"conference","publication":"ECIS 2013 Proceedings"},{"main_file_link":[{"url":"https://groups.uni-paderborn.de/nt/pubs/2013/SchHaeb2013.pdf","open_access":"1"}],"title":"Sampling Rate Synchronisation in Acoustic Sensor Networks with a Pre-Trained Clock Skew Error Model","author":[{"first_name":"Joerg","full_name":"Schmalenstroeer, Joerg","id":"460","last_name":"Schmalenstroeer"},{"first_name":"Reinhold","last_name":"Haeb-Umbach","full_name":"Haeb-Umbach, Reinhold","id":"242"}],"date_created":"2019-07-12T05:30:15Z","oa":"1","date_updated":"2023-10-26T08:11:01Z","citation":{"bibtex":"@inproceedings{Schmalenstroeer_Haeb-Umbach_2013, title={Sampling Rate Synchronisation in Acoustic Sensor Networks with a Pre-Trained Clock Skew Error Model}, booktitle={21th European Signal Processing Conference (EUSIPCO 2013)}, author={Schmalenstroeer, Joerg and Haeb-Umbach, Reinhold}, year={2013} }","short":"J.

So far, very little is known about the relationship between sentiments and network emergence, dissemination patternsand possible differences between positive and negative sentiments. The dissemination patterns analyzed in this study consist of network motifs based on triples of actors and the ties among them. These motifs are associated with common social network effects to derive meaningful insights about dissemination activities. The data basis includes several thousand social networks with textual messages classified according to embedded positive and negative sentiments. Based on this data, sub-networks are extracted and analyzed with a dynamic network motif analysis to determine dissemination patterns and associated network effects. Results indicate that the emergence of digital social networks exhibits a strong tendency towards reciprocity, followed by the dominance ofhierarchy as an intermediate step leading to social clustering with hubs and transitivity effects for both positive and negative sentiments to the same extend. Sentiments embedded in exchanged textual messages do only play a secondary role in network emergence and do not express differences regarding the emergence of network patterns.","lang":"eng"}],"status":"public","_id":"13331","department":[{"_id":"198"}],"user_id":"62809","keyword":["Social Network Analysis","Dynamic Network Motif Analysis","Sentiment Dissemination","Networking Effects","Triads"],"language":[{"iso":"eng"}]},{"quality_controlled":"1","citation":{"ieee":"M.

The conditional independence assumption, prevalent in hidden Markov model-based ASR, is relaxed to obtain a clean speech posterior that is conditioned on the complete observed feature vector sequence. This is a more informative posterior than one conditioned only on the current observation. The novel decoding is used to obtain a transmission-error robust remote ASR system, where the speech capturing unit is connected to the decoder via an error-prone communication network. We show how the clean speech posterior can be computed for communication links being characterized by either bit errors or packet loss. Recognition results are presented for both distributed and network speech recognition, where in the latter case common voice-over-IP codecs are employed.","lang":"eng"}],"publication":"IEEE Transactions on Audio, Speech, and Language Processing","type":"journal_article","language":[{"iso":"eng"}],"keyword":["automatic speech recognition","bit errors","codecs","communication links","corrupted observations","decoding","distributed speech recognition","error-prone communication network","feature vector sequence","hidden Markov model-based ASR","hidden Markov models","inter-frame correlation","Internet telephony","network speech recognition","packet loss","speech posterior","speech recognition","transmission error robust speech recognition","uncertainty decoding","voice-over-IP codecs"],"department":[{"_id":"54"}],"user_id":"44006","_id":"11820"},{"status":"public","abstract":[{"lang":"eng","text":"In order to avoid over-regulation, some countries have experimented with what might be called threat-based regulation. The idea is - similarly to the contestable market model - that actual regulation may not be necessary as long as the threat of regulation is credible. In that case, so the idea, even monopolies will abstain from setting monopolistic prices in order to avoid being regulated. As experience from Germany and New Zealand has demonstrated, there are quite a number of problems associated with threat-based regulatory systems. The most significant problem has turned out to be the likely under-regulation and according welfare losses from market power, and in this context, a critical issue that has been identified is the credibility of the regulatory threat. If the threat of regulation is not credible, a light-handed regulatory regime (LHRR) amounts to leaving monopolistic firms unregulated, clearly an undesirable situation from a welfare point of view. This failure of threat-based regulatory systems results from potential free-rider problems associated with good corporate behaviour (as in the case of Germany's electricity market) as well as the lack of credibility of the threat either because of the weakness of the enforcement authorities or due to political constraints. Furthermore, a problem emerges if exercising the threat of regulation implies an abandonment of the LHRR and a corresponding substitution with heavy-handed ex ante regulation. An innovative way out of this dilemma has been the quasi-automatic threshold system originally designed for New Zealand's electricity distribution networks, which aims at simulating the pressures that companies would face in competitive markets.
