Furthermore, changing conditions like temperature and pressure result in varying acoustic properties of the liquid. That might necessitate an adaption of the ultrasound irradiation. To detect such changes during operation, process monitoring is desired. Labor intensive processes, that might be carried out for several hours, also require process monitoring to increase their reliability by detection of changes or malfunctions during operation. In some applications cavitation detection and monitoring can be achieved by the application of sensors in the sound field. Though the application of sensors is possible, this necessitates modifications on the system and the sensor might disturb the sound field. In other applications harsh, process conditions prohibit the application of sensors in the sound field. Therefore alternative techniques for cavitation detection and monitoring are desired. The applicability of an external microphone and a self-sensing ultrasound transducer for cavitation detection were experimentally investigated.

These so called self-optimizing systems adapt their objectives and behavior autonomously and flexibly to changing operating conditions. On the one hand, securing the dependability of such systems is challenging due to their complexity and non-deterministic behavior. On the other hand, self-optimization can be used to increase the dependability of the system during its operation. However, it has to be ensured, that the self-optimization works dependable itself. To cope with these challenges, the multi-level dependability concept was developed. It enables predictive condition monitoring, influences the objectives of the system and determines suitable means to improve the system's dependability during its operation. In this contribution we introduce a procedure for the conceptual design of an advanced condition monitoring based on the system's principle solution. The principle solution describes the principal operation mode of the system and its desired behavior. It is modeled using the specification technique for the domain-spanning description of the principle solution of a self-optimizing system and consists of a coherent system of eight partial models (e.g. requirements, active structure, system of objectives, behavior, etc.). The partial models are analyzed separately in order to derive the components of the multi-level dependability concept. In particular, the reliability analysis of the partial model active structure is performed to identify the system elements to be monitored and parameters to be measured. The principle solution is extended accordingly: e.g. with system elements required for the realization of the dependability concept. The advantages of the method are shown on the self-optimizing guidance module of a railroad vehicle."}],"publication":"Proceedings of the 11th International Probabilistic Safety Assessment and Management Conference (PSAM11) and The Annual European Safety and Reliability Conference (ESREL2012)","type":"conference","title":"Conceptual Design of Advanced Condition Monitoring for a Self-Optimizing System based on its Principle Solution","date_created":"2019-05-13T13:41:34Z","author":[{"full_name":"Sondermann-Wölke , Christoph","last_name":"Sondermann-Wölke ","first_name":"Christoph"},{"last_name":"Meyer","full_name":"Meyer, Tobias","first_name":"Tobias"},{"full_name":"Dorociak, Rafal","last_name":"Dorociak","first_name":"Rafal"},{"last_name":"Gausemeier","full_name":"Gausemeier, Jürgen","first_name":"Jürgen"},{"full_name":"Sextro, Walter","id":"21220","last_name":"Sextro","first_name":"Walter"}],"date_updated":"2022-01-06T07:04:20Z","citation":{"ama":"Sondermann-Wölke C, Meyer T, Dorociak R, Gausemeier J, Sextro W.

It leads to a simulation flow with two phases towards an enhanced mutation analysis result. First in a random simulation phase, an in-loop heuristics is deployed and adjusts dynamically the test probability distribution so as to improve the coverage efficiency. Next, for each remaining hard-to-kill mutant, a search heuristics on test input space is developed to iteratively locate a target test, using a specific objective cost function for the goal of killing HDL mutant.

An objective cost function is defined on the test input space and serves the guidance of search for fault-detecting test data. This is done by first mapping the simulation traces under a test onto a control and data flow graph structure which is extracted from the design. Then the progress of fault detection can be measured quantitatively on this graph to be the cost value. By minimizing this cost we approach the target test data. The effectiveness of the cost function is investigated under an example neighborhood search scheme. Case study with a floating point arithmetic IP design has shown that the cost function is able to guide effectively the search procedure towards a fault-detecting test.

Online service providers may find themselves maxed out at peak operation levels during high-traffic timeslots but too little demand during low-traffic timeslots, although the latter is becoming less frequent. At this point not only deciding which user is allocated what level of service becomes essential, but also the magnitude of the service provided, can be controlled by pricing. Pricing is an important factor when efficient and acceptable allocation of resources between individuals must be reached. Without prices, transferring or sharing goods would be impossible. In sharing information, pricing a product however is not as simple as relatively pricing an apple or a pear. Often the costs, and hence the prices are simply unknown. Backed by this scenario, the online services market could be combined with the market design mechanism of diamonds. For this we propose an ultimatum pricing strategy which effectively allows for valuations to be accounted for, but no longer a necessity when pricing in grid, cloud or other online computing environments.","lang":"eng"}],"status":"public","file":[{"content_type":"application/pdf","relation":"main_file","creator":"hsiemes","date_created":"2018-12-11T15:22:41Z","date_updated":"2018-12-13T15:20:13Z","file_name":"Take it or leave it - ECIS - Proof.pdf","access_level":"open_access","file_id":"6191","file_size":247621}],"_id":"5690","department":[{"_id":"277"}],"user_id":"61579","keyword":["Posted Price","Ultimatum Game","Energy Efficiency","Mechanism Design"],"ddc":["000"],"file_date_updated":"2018-12-13T15:20:13Z","language":[{"iso":"eng"}],"extern":"1"},{"publication":"Industrial Informatics (INDIN), 2010 8th IEEE International Conference on","type":"conference","abstract":[{"text":"Self-optimizing systems are able to adapt their behavior autonomously according to their current self-determined objectives.

This paper presents a guideline for the dependability-oriented design of self-optimizing systems, which integrates established classical methods like failure mode and effects analysis as well as methods based on self-optimization. On the one hand self-optimization is used to increase the dependability of the system by integrating objectives like safety, availability, and reliability to the objectives of the system. On the other hand methods are required to ensure the self-optimization itself. As basis for this guideline serves the principle solution of the system. The six phases of the guideline extend the design process and lead to an enhanced principle solution.

Our approach is aimed at the enhancement of the logarithmic Mel power spectrum, which is computed at an intermediate stage to obtain the widely used Mel frequency cepstral coefficients (MFCCs). Given the reverberant logarithmic Mel power spectral coefficients (LMPSCs), a minimum mean square error estimate of the clean LMPSCs is computed by carrying out Bayesian inference. We employ switching linear dynamical models as an a priori model for the dynamics of the clean LMPSCs. Further, we derive a stochastic observation model which relates the clean to the reverberant LMPSCs through a simplified model of the room impulse response (RIR). This model requires only two parameters, namely RIR energy and reverberation time, which can be estimated from the captured microphone signal. The performance of the proposed enhancement technique is studied on the AURORA5 database and compared to that of constrained maximum-likelihood linear regression (CMLLR). It is shown by experimental results that our approach significantly outperforms CMLLR and that up to 80\\% of the errors caused by the reverberation are recovered. In addition to the fact that the approach is compatible with the standard MFCC feature vectors, it leaves the ASR back-end unchanged.

What has to be taken into account when developing a methodology for writing research from a cultural-historical and dialogical perspective? Firstly, writing is not separated from other forms of speech activity like interpersonal and intrapersonal speech. Thus, inner dialogue and the addressed character of writing become crucial notions to be methodologically considered. Secondly, contrary to current writing research traditions such as literacy studies and studies of the writing process in cognitive psychology, both individual writing processes and socio-cultural writing practices as well as their relationship must be considered. These reflections lead towards the conclusion that writing is not fully accessible to external observation or to introspection. In consequence, a suggestion of a methodological approach is given, inspired by the activity theoretically informed method of auto-confrontation. The proposed method consists of two phases: a) videotaping of a writing episode and b) co-analysis of the videotaped writing episode in dialogue between writer and researcher. The second phase transfers the writing activity into a new context where understanding it becomes possible. The co-analysis makes involved positions audible: positions of the writer and of the researcher, of real and imagined readers as well as intersubjective and community-related positions. Finally, implications of the proposed research setting are discussed and evaluated with regard to the theoretical grounding. An instance of the methodology to be sketched in this article was developed in the context of the author’s dissertation project in preparation at Ludwig-Maximilians-Universität in Munich, Germany with the working title «Writing processes and writing practices.

Constraints violation within the neighbourhood of a design is considered as part of a measurement for degree of feasibility and robustness of a solution."}],"status":"public","type":"journal_article","publication":"CIRP Journal of Manufacturing Science and Technology","keyword":["Roll cooling design","Uncertainty","Design optimisation","Multi-objective optimisation","Constraint in design"],"language":[{"iso":"eng"}],"_id":"46411","user_id":"15504","department":[{"_id":"34"},{"_id":"819"}],"year":"2010","citation":{"ieee":"Y.

In order to support stepwise RTOS software refinement from system level to the target software, each task can be separately migrated between the native execution and the ISS. By adapting the dynamic binary translation approach to an efficient but yet very accurate synchronization scheme the overhead of QEMU user mode execution is only factor two compared to native SystemC. Furthermore, the simulation speed increases almost linearly according to the utilization of the task set abstracted by the native execution.

It has been defined in terms of child-directed speech (Motherese), child-directed motion (Motionese), and contingency. In the field of developmental robotics, research often assumes that in human-robot interaction (HRI), robots are treated similar to infants, because their immature cognitive capabilities benefit from this behavior. However, according to our knowledge, it has barely been studied whether this is true and how exactly humans alter their behavior towards a robotic interaction partner. In this paper, we present results concerning the acceptance of a robotic agent in a social learning scenario obtained via comparison to adults and 8-11 months old infants in equal conditions. These results constitute an important empirical basis for making use of tutoring behavior in social robotics. In our study, we performed a detailed multimodal analysis of HRI in a tutoring situation using the example of a robot simulation equipped with a bottom-up saliency-based attention model. Our results reveal significant differences in hand movement velocity, motion pauses, range of motion, and eye gaze suggesting that for example adults decrease their hand movement velocity in an Adult-Child Interaction (ACI), opposed to an Adult-Adult Interaction (AAI) and this decrease is even higher in the Adult-Robot Interaction (ARI). We also found important differences between ACI and ARI in how the behavior is modified over time as the interaction unfolds. These findings indicate the necessity of integrating top-down feedback structures into a bottom-up system for robots to be fully accepted as interaction partners."}],"publication":"Development and Learning, 2009.

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."}],"status":"public","date_updated":"2022-01-06T06:51:10Z","oa":"1","volume":16,"author":[{"full_name":"Ion, Valentin","last_name":"Ion","first_name":"Valentin"},{"first_name":"Reinhold","full_name":"Haeb-Umbach, Reinhold","id":"242","last_name":"Haeb-Umbach"}],"date_created":"2019-07-12T05:28:53Z","title":"A Novel Uncertainty Decoding Rule With Applications to Transmission Error Robust Speech Recognition","doi":"10.1109/TASL.2008.925879","main_file_link":[{"open_access":"1","url":"https://groups.uni-paderborn.de/nt/pubs/2008/IoHa08-1.pdf"}],"issue":"5","year":"2008","page":"1047-1060","intvolume":" 16","citation":{"ama":"Ion V, Haeb-Umbach R.
