Synthesis and verification processes are invoked in each iteration to evaluate the found solutions and to guide the search algorithm. As a result, a large number of approximate circuits is subjected to analysis - leading to long runtimes - but only a few approximate circuits might form an acceptable solution.\r\n\r\nIn this paper, we present our Jump Search (JS) method which seeks to reduce the runtime of an approximation process by reducing the number of expensive synthesis and verification steps. To reduce the runtime, JS computes impact factors for each approximation candidate in the circuit to create a selection of approximate circuits without invoking synthesis or verification processes. We denote the selection as path from which JS determines the final solution. In our experimental results, JS achieved speed-ups of up to 57x while area savings remain comparable to the reference search method, Simulated Annealing.","lang":"eng"}],"publication":"Proceedings of the 2019 on Great Lakes Symposium on VLSI - GLSVLSI '19","language":[{"iso":"eng"}],"keyword":["Approximate computing","design automation","parameter selection","circuit synthesis"],"year":"2019","title":"Jump Search: A Fast Technique for the Synthesis of Approximate Circuits","date_created":"2019-07-08T15:13:10Z","publisher":"ACM"},{"doi":"10.1007/s00180-017-0742-2","title":"OpenML: An R Package to Connect to the Machine Learning Platform OpenML","date_created":"2023-11-14T15:58:57Z","author":[{"last_name":"Casalicchio","full_name":"Casalicchio, Giuseppe","first_name":"Giuseppe"},{"orcid":"0000-0002-4121-4668","last_name":"Bossek","id":"102979","full_name":"Bossek, Jakob","first_name":"Jakob"},{"full_name":"Lang, Michel","last_name":"Lang","first_name":"Michel"},{"first_name":"Dominik","full_name":"Kirchhoff, Dominik","last_name":"Kirchhoff"},{"first_name":"Pascal","last_name":"Kerschke","full_name":"Kerschke, Pascal"},{"last_name":"Hofner","full_name":"Hofner, Benjamin","first_name":"Benjamin"},{"first_name":"Heidi","full_name":"Seibold, Heidi","last_name":"Seibold"},{"last_name":"Vanschoren","full_name":"Vanschoren, Joaquin","first_name":"Joaquin"},{"first_name":"Bernd","full_name":"Bischl, Bernd","last_name":"Bischl"}],"volume":34,"date_updated":"2023-12-13T10:51:17Z","citation":{"chicago":"Casalicchio, Giuseppe, Jakob Bossek, Michel Lang, Dominik Kirchhoff, Pascal Kerschke, Benjamin Hofner, Heidi Seibold, Joaquin Vanschoren, and Bernd Bischl. “OpenML: An R Package to Connect to the Machine Learning Platform OpenML.” Computational Statistics 34, no. 3 (2019): 977–991. https://doi.org/10.1007/s00180-017-0742-2.","ieee":"G.

In comparison to aluminium-copper, copper-copper interconnections require increased normal forces and ultrasonic power, which might lead to substrate damage due to increased mechanical stresses. One option to raise friction energy without increasing vibration amplitude between wire and substrate or bonding force is the use of two-dimensional vibration. The first part of this contribution reports on the development of a novel bonding system that executes two-dimensional vibrations of a tool-tip to bond a nail- like pin onto a copper substrate. Since intermetallic bonds only form properly when surfaces are clean, oxide free and activated, the geometries of tool-tip and pin were optimised using finite element analysis. To maximize the area of the bonded annulus the distribution of normal pressure was optimized by varying the convexity of the bottom side of the pin. Second, a statistical model obtained from an experimental parameter study shows the influence of different bonding parameters on the bond result. To find bonding parameters with the minimum number of tests, the experiments have been planned using a D-optimal experimental design approach.","lang":"eng"}],"status":"public","date_updated":"2020-05-07T05:33:56Z","author":[{"id":"66833","full_name":"Dymel, Collin","last_name":"Dymel","first_name":"Collin"},{"first_name":"Paul","full_name":"Eichwald, Paul","last_name":"Eichwald"},{"first_name":"Reinhard","last_name":"Schemmel","full_name":"Schemmel, Reinhard","id":"28647"},{"full_name":"Hemsel, Tobias","id":"210","last_name":"Hemsel","first_name":"Tobias"},{"last_name":"Brökelmann","full_name":"Brökelmann, Michael","first_name":"Michael"},{"full_name":"Hunstig, Matthias","last_name":"Hunstig","first_name":"Matthias"},{"first_name":"Walter","id":"21220","full_name":"Sextro, Walter","last_name":"Sextro"}],"date_created":"2019-05-27T10:18:10Z","title":"Numerical and statistical investigation of weld formation in a novel two-dimensional copper-copper bonding process","quality_controlled":"1","year":"2018","citation":{"apa":"Dymel, C., Eichwald, P., Schemmel, R., Hemsel, T., Brökelmann, M., Hunstig, M., & Sextro, W.

Aiming to enhance the social relevance, usability and sustainability of technological products and solutions, society and public institutions such as research funding organizations increasingly expect engineers to include inter- and transdisciplinary approaches into the development of new technologies. Engineering research and education, however, are particularly challenging areas to realize inter- and transdisciplinary collaborations, for manifold reasons.\r\nThis contribution presents methods and results of an inter- and transdisciplinary research and education strategy designed to meet the particular requirements of engineers and engineering students. It starts with a brief discussion of typical challenges regarding inter- and transdisciplinary approaches in engineering (research topics, research culture, skills, time, and barriers of lay people to involve in technology development). Secondly, it presents the methods developed to overcome those challenges within the context of the NRW Fortschrittskolleg \"Light - Efficient - Mobile\" (FK LEM). Founded in 2014, the FK LEM is a PhD programm focuses on lightweight construction, but with a special emphasis on how lightweight technologies are connected to different areas of society, to societal actors and technology users, and to the needs of a diversity of social groups. In order to explore these connections, we organized three workshops to bring public service, civil society, industry, practitioners and engineers together to discuss the perceived needs in those areas, and the potential of lightweight solutions. Topically, the workshops were dedicated to the fields of Rescue & Security Services; Care, Mobility & Assisted Living; and Sustainable Ressources & Climate Protection. Methodologically, we applied a pragmatic but valid approach to focus groups and discourse analysis. Results of the workshops in terms of directions for future research, epistemological and ethical dimensions of lightweight engineering are presented in the third part of our contribution. Finally, we discuss how our method and experience can be transferred into other engineering and educational contexts. With other words, how empowering students, engineers and the public to involve in inter- and transdisciplinary engineering processes can be achieved, and how this empowerment supports the development of innovative technologies as well as engineers’ skills to design technology in line with societies’ needs and challenges."}],"status":"public","file":[{"date_updated":"2021-09-14T21:31:21Z","date_created":"2021-09-14T21:31:21Z","creator":"innem","file_size":259154,"access_level":"closed","file_name":"Horwath_etal_2018.pdf","file_id":"24469","content_type":"application/pdf","success":1,"relation":"main_file"}]},{"title":"Recombinant Service Systems Engineering","publisher":"SpringerNature","date_created":"2018-09-19T13:53:51Z","year":"2018","quality_controlled":"1","issue":"5","keyword":["Service engineering","Recombinant innovation","(Product-)service system","Design science research","New service development"],"language":[{"iso":"eng"}],"abstract":[{"text":"Although many methods have been proposed for engineering service systems and customer solutions, most of these approaches give little consideration to recombinant service innovation. Recombinant innovation refers to reusing and integrating resources that were previously unconnected. In an age of networked products and data, we can expect that many service innovations will be based on adding, dissociating, and associating existing value propositions by accessing internal and external resources instead of designing them from scratch. The purpose of this paper is to identify if current service engineering approaches account for the mechanisms of recombinant innovation and to design a method for recombinant service systems engineering. In a conceptual analysis of 24 service engineering methods, the study identified that most methods (1) focus on designing value propositions instead of service systems, (2) view service independent of physical goods, (3) are either linear or iterative instead of agile, and (4) do not sufficiently address the mechanisms of recombinant innovation. The paper discusses how these deficiencies can be remedied and designs a revised service systems engineering approach that reorganizes service engineering processes according to four design principles. The method is demonstrated with the recombinant design of a service system for predictive maintenance of agricultural machines.","lang":"eng"}],"publication":"Business & Information Systems Engineering","doi":"10.1007/s12599-018-0526-4","date_updated":"2024-04-18T12:57:19Z","volume":60,"author":[{"id":"59677","full_name":"Beverungen, Daniel","last_name":"Beverungen","first_name":"Daniel"},{"id":"60612","full_name":"Lüttenberg, Hedda","last_name":"Lüttenberg","first_name":"Hedda"},{"full_name":"Wolf, Verena","id":"23633","last_name":"Wolf","first_name":"Verena"}],"page":"377-391","intvolume":" 60","citation":{"apa":"Beverungen, D., Lüttenberg, H., & Wolf, V.

Reliability of these transducers is an important aspect in their application.

This is achieved by utilizing the health state and RUL predictions to adaptively control the usage of the components or to schedule appropriate maintenance without interrupting operation. In this work, a prognostic approach utilizing self-sensing, where electric signals of a piezoelectric transducer are used as the condition monitoring data, is proposed. The approach involves training machine learning algorithms to model the degradation of the transducers through a health index and the use of the learned model to estimate the health index of similar transducers. The current health index is then used to estimate RUL of test components. The feasibility of the approach is demonstrated using piezoelectric bimorphs and the results show that the method is accurate in predicting the health index and RUL."}],"status":"public","_id":"9978","department":[{"_id":"151"}],"user_id":"55222","keyword":["Estimation of Remaining Useful Lifetime of Piezoelectric Transducers Based on Self-Sensing"],"language":[{"iso":"eng"}],"quality_controlled":"1","year":"2017","page":"1 - 10","citation":{"ama":"Kimotho JK, Sextro W, Hemsel T.

Methodologists have drawn attention to the question of how we can leverage the value of LRs to preserve and generate knowledge. The panelists who participated in the discussion of ?Standalone Literature Reviews in IS Research: What Can Be Learnt from the Past and Other Fields?? at ICIS 2016 in Dublin acknowledged this significant issue and debated a) what the IS field can learn from other fields and where IS-specific challenges occur, b) how the IS field should move forward to foster the genre of LRs, and c) what best practices are to train doctoral IS students in publishing LRs. This article reports the key takeaways of this panel discussion. Guidance for IS scholars is provided on how to conduct LRs that contribute to the cumulative knowledge development within and across the IS field to best prepare the next generation of IS scholars."}],"publication":"Communications of the AIS","title":"Literature Reviews in IS Research: What Can Be Learnt from the Past and Other Fields?","date_created":"2018-11-14T14:25:40Z","publisher":"Association for Information Systems (AIS)","year":"2017","file_date_updated":"2018-12-13T15:07:15Z","extern":"1","department":[{"_id":"277"}],"user_id":"61579","_id":"5633","status":"public","type":"journal_article","volume":40,"author":[{"first_name":"Guido","last_name":"Schryen","full_name":"Schryen, Guido","id":"72850"},{"full_name":"Benlian, Alexander","last_name":"Benlian","first_name":"Alexander"},{"last_name":"Rowe","full_name":"Rowe, Frantz","first_name":"Frantz"},{"last_name":"Shirley","full_name":"Shirley, Gregor","first_name":"Gregor"},{"first_name":"Kai","last_name":"Larsen","full_name":"Larsen, Kai"},{"full_name":"Petter, Stacie","last_name":"Petter","first_name":"Stacie"},{"first_name":"Guy","full_name":"Par{\\'e}, Guy","last_name":"Par{\\'e}"},{"full_name":"Wagner, Gerit","last_name":"Wagner","first_name":"Gerit"},{"full_name":"Haag, Steffi","last_name":"Haag","first_name":"Steffi"},{"last_name":"Yasasin","full_name":"Yasasin, Emrah","first_name":"Emrah"}],"date_updated":"2022-01-06T07:02:14Z","oa":"1","page":"557 - 569","intvolume":" 40","citation":{"short":"G.

Developing this competence should be a main aspect of early childhood teachers’ education. This is, however, not the case in all countries. Consequently, high-quality professional development courses are needed. Based on research results, we developed a competence-oriented continuous professional development course (\"EmMa\") and examined the effects of \"EmMa\" by asking: How does \"EmMa\" affect the development of early childhood teachers’ i) mathematical content knowledge, ii) mathematical pedagogical content knowledge and iii) beliefs towards mathematics in general? To answer these questions, we conducted a pre-test/post-test study including a control group with 99 in-service early childhood teachers. Results show that the course affected teachers’ mathematical pedagogical content knowledge and static orientation towards mathematics positively. From this we conclude that scaling-up \"EmMa\" might be a suitable approach to bridge the gap between pre-service education with nearly no mathematics and the challenges of early mathematics education."}],"type":"journal_article","publication":"Mathematics Teacher Education and Development (MTED)","language":[{"iso":"eng"}],"extern":"1","keyword":["Beliefs","Competency Based Teacher Education","Control Groups","Early Childhood Education","Faculty Development","Foreign Countries","Inservice Teacher Education","Intervention","Mathematical Aptitude","Mathematics Skills","Pedagogical Content Knowledge","Preschool Teachers","Pretests Posttests","Professional Continuing Education","Statistical Analysis","Teacher Competency Testing"],"user_id":"49063","department":[{"_id":"611"},{"_id":"97"}],"_id":"36481"},{"file_date_updated":"2018-03-21T12:29:37Z","department":[{"_id":"36"},{"_id":"1"},{"_id":"579"}],"series_title":"Lecture Notes in Computer Science","user_id":"477","_id":"191","project":[{"_id":"1","name":"SFB 901"},{"_id":"3","name":"SFB 901 - Project Area B"},{"name":"SFB 901 - Subproject B1","_id":"9"}],"status":"public","editor":[{"first_name":"Elisabeth ","full_name":"Métais, Elisabeth ","last_name":"Métais"},{"full_name":"Meziane, Farid ","last_name":"Meziane","first_name":"Farid "},{"full_name":"Saraee, Mohamad ","last_name":"Saraee","first_name":"Mohamad "},{"first_name":"Vijayan ","last_name":"Sugumaran","full_name":"Sugumaran, Vijayan "},{"first_name":"Sunil ","full_name":"Vadera, Sunil ","last_name":"Vadera"}],"type":"conference","conference":{"name":"21st International Conference on Applications of Natural Language to Information Systems (NLDB 2016)","start_date":"2016-06-22","end_date":"2016-06-24","location":"Salford, UK"},"doi":"10.1007/978-3-319-41754-7_4","volume":9612,"author":[{"id":"42496","full_name":"Geierhos, Michaela","last_name":"Geierhos","orcid":"0000-0002-8180-5606","first_name":"Michaela"},{"id":"38837","full_name":"Bäumer, Frederik Simon","last_name":"Bäumer","first_name":"Frederik Simon"}],"date_updated":"2022-01-06T06:53:58Z","page":"37-47","intvolume":" 9612","citation":{"bibtex":"@inproceedings{Geierhos_Bäumer_2016, place={Cham, Switzerland}, series={Lecture Notes in Computer Science}, title={How to Complete Customer Requirements: Using Concept Expansion for Requirement Refinement}, volume={9612}, DOI={10.1007/978-3-319-41754-7_4}, booktitle={Proceedings of the 21st International Conference on Applications of Natural Language to Information Systems (NLDB)}, publisher={Springer}, author={Geierhos, Michaela and Bäumer, Frederik Simon}, editor={Métais, Elisabeth and Meziane, Farid and Saraee, Mohamad and Sugumaran, Vijayan and Vadera, Sunil Editors}, year={2016}, pages={37–47}, collection={Lecture Notes in Computer Science} }","short":"M.

Since customer requirements are often written in natural language by end users, they lack precision, completeness and consistency. Although user stories are often used in the requirement elicitation process in order to describe the possibilities how to interact with the software, there is always something unspoken. Here, we present techniques how to automatically refine vague software descriptions. Thus, we can bridge the gap by first revising natural language utterances from higher-level to more detailed customer requirements, before functionality matters. We therefore focus on the resolution of semantically incomplete user-generated sentences (i.e. non-instantiated arguments of predicates) and provide ontology-based gap-filling suggestions how to complete unverbalized information in the user’s demand."}],"publication":"Proceedings of the 21st International Conference on Applications of Natural Language to Information Systems (NLDB)","title":"How to Complete Customer Requirements: Using Concept Expansion for Requirement Refinement","date_created":"2017-10-17T12:41:29Z","publisher":"Springer","year":"2016","quality_controlled":"1"},{"department":[{"_id":"181"}],"user_id":"37741","_id":"5700","language":[{"iso":"eng"}],"keyword":["Research","Service theory"],"article_type":"original","publication":"Journal of Service Management","type":"journal_article","status":"public","abstract":[{"lang":"eng","text":"Purpose\r\n– The purpose of this paper is to examine the nature of context and its implications for theory and research in service. \r\n\r\nDesign/methodology/approach\r\n– This is a conceptual paper based on exploring existing research and theory related to context in service research. \r\n\r\nFindings\r\n– The characteristics of service make context both important and challenging, there is great contextual diversity in service research as reflected, for example in ecosystems made up of multiple contextual variables. There is a need to identify the context-specific nature of middle range theory and the contextual logic of general theory. The authors explore the challenges of context for service theory and how we might learn from theory in a particular context and test or adapt it in other contexts. \r\n\r\nOriginality/value\r\n– The findings of this paper are of value to researchers seeking to develop and justify theory in service research (general, middle range or theory in use)."}],"volume":27,"date_created":"2018-11-15T11:19:00Z","author":[{"first_name":"Chris","last_name":"Voss","full_name":"Voss, Chris"},{"first_name":"Helen","last_name":"Perks","full_name":"Perks, Helen"},{"full_name":"Sousa, Rui","last_name":"Sousa","first_name":"Rui"},{"last_name":"Witell","full_name":"Witell, Lars","first_name":"Lars"},{"first_name":"Nancy","last_name":"Wünderlich","full_name":"Wünderlich, Nancy","id":"36392"}],"publisher":"Emerald Group Publishing Limited","date_updated":"2022-01-06T07:02:36Z","title":"Reflections on Context in Service Research.","issue":"1","publication_status":"published","intvolume":" 27","page":"30-36","citation":{"chicago":"Voss, Chris, Helen Perks, Rui Sousa, Lars Witell, and Nancy Wünderlich. “Reflections on Context in Service Research.” Journal of Service Management 27, no. 1 (2016): 30–36.","ieee":"C.
