For the traveling salesperson problem (TSP) a plethora of features have been suggested. Most of these features are, if at all, only normalized imprecisely raising the issue of feature values being strongly affected by the instance size. Such artifacts may have detrimental effects on algorithm selection models. We propose a normalization for two feature groups which stood out in multiple AS studies on the TSP: (a) features based on a minimum spanning tree (MST) and (b) nearest neighbor relationships of the input instance. To this end we theoretically derive minimum and maximum values for properties of MSTs and k-nearest neighbor graphs (NNG) of Euclidean graphs. We analyze the differences in feature space between normalized versions of these features and their unnormalized counterparts. Our empirical investigations on various TSP benchmark sets point out that the feature scaling succeeds in eliminating the effect of the instance size. A proof-of-concept AS-study shows promising results: models trained with normalized features tend to outperform those trained with the respective vanilla features."}],"date_created":"2023-08-04T07:18:38Z","department":[{"_id":"34"},{"_id":"819"}],"type":"journal_article","keyword":["Feature normalization","Algorithm selection","Traveling salesperson problem"],"publication_identifier":{"issn":["0304-3975"]},"author":[{"first_name":"Jonathan","last_name":"Heins","full_name":"Heins, Jonathan"},{"id":"102979","last_name":"Bossek","orcid":"0000-0002-4121-4668","first_name":"Jakob","full_name":"Bossek, Jakob"},{"first_name":"Janina","last_name":"Pohl","full_name":"Pohl, Janina"},{"id":"105520","last_name":"Seiler","first_name":"Moritz","full_name":"Seiler, Moritz"},{"last_name":"Trautmann","first_name":"Heike","orcid":"0000-0002-9788-8282","full_name":"Trautmann, Heike","id":"100740"},{"first_name":"Pascal","last_name":"Kerschke","full_name":"Kerschke, Pascal"}],"title":"A study on the effects of normalized TSP features for automated algorithm selection","year":"2023","status":"public","intvolume":" 940","date_updated":"2024-06-10T11:57:21Z","_id":"46310","language":[{"iso":"eng"}],"page":"123-145","volume":940,"doi":"https://doi.org/10.1016/j.tcs.2022.10.019","user_id":"15504"},{"publication":"2023 IEEE Symposium Series on Computational Intelligence (SSCI)","citation":{"ieee":"M.

This study analysed (i) chronotype/SJL association with visceral fat/skeletal muscle mass, (ii) the attribution to physical activity behaviour, and (iii) chronotype-specific changes in physical activity behaviour in young adults during the Covid-19 pandemic lockdown. Chronotype and SJL were derived from the Munich-Chrono-Type-Questionnaire in 320 German students (age 18–25 years) from September 2019 to January 2020, 156 of these participated in an online follow-up survey in June 2020. Body composition was assessed by bioimpedance analysis at baseline. Multivariable linear regression analyses were used to relate chronotype/SJL to body composition; the contribution of self-reported physical activity was tested by mediation analysis. At baseline, a later chronotype and a larger SJL were associated with a higher visceral fat mass (P<0.05), this relation was notably mediated by the attention to physical activity (P<0.05). Chronotype (P = 0.02) but not SJL (P = 0.87) was inversely associated with skeletal muscle mass. During the pandemic lockdown, chronotype hardly changed, but SJL was reduced. Timing and physical activity behaviour remained in most participants and changes were unrelated to chronotype (all P>0.07). A later chronotype/higher SJL may increase the risk of a higher visceral fat mass even in this relatively healthy sample, which may be partly due to their physical activity behaviour. Despite a reduction in SJL during the pandemic lockdown, later chronotypes did not change their physical activity behaviour more than earlier chronotypes."}],"publication":"PLOS ONE","issue":"1","doi":"10.1371/journal.pone.0279620","language":[{"iso":"eng"}],"article_number":"e0279620","intvolume":" 18","date_updated":"2023-01-24T11:54:46Z","publication_status":"published","publication_identifier":{"issn":["1932-6203"]},"author":[{"id":"49428","orcid":"0000-0001-5351-1785","first_name":"Betina","last_name":"Krueger","full_name":"Krueger, Betina"},{"id":"77099","full_name":"Stutz, Bianca","first_name":"Bianca","last_name":"Stutz"},{"full_name":"Jankovic, Nicole","last_name":"Jankovic","first_name":"Nicole"},{"last_name":"Alexy","first_name":"Ute","full_name":"Alexy, Ute"},{"full_name":"Kilanowski, Anna","first_name":"Anna","last_name":"Kilanowski"},{"id":"88682","first_name":"Lars","orcid":"0000-0003-1603-3133","last_name":"Libuda","full_name":"Libuda, Lars"},{"full_name":"Buyken, Anette E.","last_name":"Buyken","first_name":"Anette E.","id":"65985"}],"title":"The association of chronotype and social jet lag with body composition in German students: The role of physical activity behaviour and the impact of the pandemic lockdown","year":"2023","citation":{"mla":"Krueger, Betina, et al. “The Association of Chronotype and Social Jet Lag with Body Composition in German Students: The Role of Physical Activity Behaviour and the Impact of the Pandemic Lockdown.” PLOS ONE, vol. 18, no. 1, e0279620, Public Library of Science (PLoS), 2023, doi:10.1371/journal.pone.0279620.","bibtex":"@article{Krueger_Stutz_Jankovic_Alexy_Kilanowski_Libuda_Buyken_2023, title={The association of chronotype and social jet lag with body composition in German students: The role of physical activity behaviour and the impact of the pandemic lockdown}, volume={18}, DOI={10.1371/journal.pone.0279620}, number={1e0279620}, journal={PLOS ONE}, publisher={Public Library of Science (PLoS)}, author={Krueger, Betina and Stutz, Bianca and Jankovic, Nicole and Alexy, Ute and Kilanowski, Anna and Libuda, Lars and Buyken, Anette E.}, year={2023} }","ama":"Krueger B, Stutz B, Jankovic N, et al.

The list consists of 356 foods selected for analysis in order to ensure ≥90% coverage of the diet. Recently, new food consumption data for children (0.5–<6 and 6–<12 years) in Germany became available, which raised the opportunity to evaluate the applicability of the MEAL food list 2016 on new data.\r\n \r\n Objective\r\n We tested the hypotheses that the MEAL food list 2016 also covers ≥90% of the diet of the new collected food consumption data, and that the selection of foods from younger children and adults was sufficient to also cover the middle age group (6–<12 years). Strategies for updating the existing food list were assessed.\r\n \r\n Methods\r\n Three approaches evaluated the reusability and potential adjustment strategies of the existing food list. Approach 1 applied the existing food list to new food consumption data. Approach 2 allowed the extension of the existing food list to improve coverage of food consumption. Approach 3 set up a new food list based on the new data.\r\n \r\n Results\r\n The MEAL food list 2016 covered 94% of the overall diet of the new collected food consumption data. The diet of the middle age group was sufficiently covered with 91%. However, coverage on main food group or population subgroup level was <90% in some cases. Approach 3 most accurately identified relevant modifications to the existing food list. 94% of the MEAL food list 2016 could be re-used and 51 new foods were identified as potentially relevant.\r\n \r\n Significance\r\n The results suggest that a high investment in the coverage of a TDS food list will lower the effort and the resources to keep data updated in the long-term.\r\n \r\n Impact\r\n There is no established approach to update a TDS food list. This study provides comparative approaches to handle newly collected food consumption data for follow-on TDS activities. The results provide useful information for institutions planning or updating a TDS. Furthermore, new food consumption data for children in Germany recently became available and are here presented for the first time.\r\n ","lang":"eng"}],"citation":{"short":"A.E. Kolbaum, S. Ptok, C.

Popular applications are image denoising, sparse\r\nregression and machine learning. Since the choice of the regularization\r\nparameter is crucial but often difficult, path-following methods are used to\r\napproximate the entire regularization path, i.e., the set of all possible\r\nsolutions for all regularization parameters. Due to their nature, the\r\ndevelopment of these methods requires structural results about the\r\nregularization path. The goal of this article is to derive these results for\r\nthe case of a smooth objective function which is penalized by a piecewise\r\ndifferentiable regularization term. We do this by treating regularization as a\r\nmultiobjective optimization problem. Our results suggest that even in this\r\ngeneral case, the regularization path is piecewise smooth. Moreover, our theory\r\nallows for a classification of the nonsmooth features that occur in between\r\nsmooth parts. This is demonstrated in two applications, namely support-vector\r\nmachines and exact penalty methods."}],"date_created":"2021-11-15T09:24:59Z","type":"journal_article","department":[{"_id":"101"},{"_id":"655"}],"year":"2023","title":"On the structure of regularization paths for piecewise differentiable regularization terms","author":[{"id":"32643","full_name":"Gebken, Bennet","first_name":"Bennet","last_name":"Gebken"},{"id":"32829","full_name":"Bieker, Katharina","last_name":"Bieker","first_name":"Katharina"},{"full_name":"Peitz, Sebastian","orcid":"0000-0002-3389-793X","last_name":"Peitz","first_name":"Sebastian","id":"47427"}],"date_updated":"2023-03-11T17:16:33Z","intvolume":" 85","main_file_link":[{"url":"https://link.springer.com/content/pdf/10.1007/s10898-022-01223-2.pdf","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1007/s10898-022-01223-2"},{"publication":"Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022)","file":[{"date_created":"2023-03-25T10:01:03Z","creator":"maxh","success":1,"content_type":"application/pdf","file_id":"43096","access_level":"closed","file_size":201942,"file_name":"HoffmannBiehler2022_indrum_congruence.pdf","date_updated":"2023-03-25T10:01:03Z","relation":"main_file"}],"date_created":"2022-06-12T11:07:34Z","type":"conference","keyword":["Teaching and learning of specific topics in university mathematics","Transition to","across and from university mathematics","Student Teachers","Geometry","Congruence","Double Discontinuity."],"department":[{"_id":"97"}],"title":"Student Teachers ’ Knowledge of Congruence before a University Course on Geometry","year":"2023","author":[{"full_name":"Hoffmann, Max","orcid":"0000-0002-6964-7123","last_name":"Hoffmann","first_name":"Max","id":"32202"},{"id":"16274","last_name":"Biehler","first_name":"Rolf","full_name":"Biehler, Rolf"}],"publication_status":"published","date_updated":"2023-03-25T10:11:35Z","main_file_link":[{"url":"https://hal.univ-reims.fr/INDRUM2022/","open_access":"1"}],"language":[{"iso":"eng"}],"file_date_updated":"2023-03-25T10:01:03Z","citation":{"chicago":"Hoffmann, Max, and Rolf Biehler. “Student Teachers ’ Knowledge of Congruence before a University Course on Geometry.” In Proceedings of the Fourth Conference of the International Network for Didactic Research in University Mathematics (INDRUM 2022, 19-22 October 2022), edited by Marı́a Trigueros, Berta Barquero, Reinhard Hochmuth, and Jana Peters.

Knowledge on the thermal conductivity of paraffins is necessary for the design and optimization of heat storage systems. However, for most paraffins solely the thermal conductivity of the liquid state has been sufficiently investigated. For the solid state, precise thermal conductivity data are only known for a few paraffins, while only generalized values are available for the remainder, some of which contradict each other. In this study, a measurement setup based on the modified guarded hot plate method is developed. It is used to investigate the thermal conductivity of several paraffines in the solid state, including pure n-docosane and its compounds with different types and concentrations of graphite. For n-docosane in the solid state, the thermal conductivity is determined to be 0.49 W/(m K). A particle size of 200 μm with a spherical shape turns out to be optimal to increase the thermal conductivity. This allows the thermal conductivity of a compound with 10% graphite to increase by a factor of three compared to the pure paraffin. Furthermore, significant differences to thermal conductivity data from the literature are found."}],"quality_controlled":"1","date_created":"2023-04-04T06:48:57Z","keyword":["Physical and Theoretical Chemistry","Condensed Matter Physics"],"type":"journal_article","department":[{"_id":"728"},{"_id":"145"},{"_id":"393"},{"_id":"9"}],"year":"2023","status":"public","title":"Thermal conductivity of solid paraffins and several n-docosane compounds with graphite","publication_identifier":{"issn":["1388-6150","1588-2926"]},"author":[{"id":"7828","first_name":"Andreas","last_name":"Paul","full_name":"Paul, Andreas"},{"id":"15164","first_name":"Elmar","last_name":"Baumhögger","full_name":"Baumhögger, Elmar"},{"id":"49826","full_name":"Dewerth, Mats-Ole","first_name":"Mats-Ole","last_name":"Dewerth"},{"last_name":"Hami Dindar","first_name":"Iman","full_name":"Hami Dindar, Iman","id":"54836"},{"full_name":"Sonnenrein, Gerrit","last_name":"Sonnenrein","first_name":"Gerrit"},{"first_name":"Jadran","last_name":"Vrabec","full_name":"Vrabec, Jadran"}],"publication_status":"published","date_updated":"2023-04-27T11:10:32Z","language":[{"iso":"eng"}],"_id":"43391","publisher":"Springer Science and Business Media LLC","user_id":"7828","doi":"10.1007/s10973-023-12107-2"},{"conference":{"location":"Nürnberg","name":"20th International Conference on Sheet Metal 2023","start_date":"2023-04-02","end_date":"2023-04-05"},"status":"public","publisher":"Materials Research Forum LLC","_id":"43044","page":"11-18","volume":25,"user_id":"82645","citation":{"ieee":"M.

The combination of incremental sheet metal forming and high-speed forming offers new possibilities for flexible forming processes in the production of large sheet metal components of increased complexity with relatively low forming energies. In this paper, the general feasibility and process differences between the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic forming were investigated. An example component made of EN AW 6016 aluminum sheet metal was thus formed incrementally by both processes and the forming result evaluated by an optical 3D measurement system. For this purpose, a forming strategy for electromagnetic incremental forming (EMIF) was developed, tested and adapted to the electrohydraulic incremental forming process (EHIF). The discharge energy, the tool displacement and the pressure field of the forming zone were determined as relevant parameters for the definition of an adequate tool path strategy. It was found that the EHIF process is less affected by larger distances between the tool and the blank, while this is a critical variable for force application to the component during EMIF. On the other hand, the more uniform pressure distribution of the EMIF process is advantageous for forming large steady component areas.

Upon heat treatment (1100 °C, 14 h), the chemical composition is homogeneous throughout the microstructure. A moderate decrease (1060 to 985 MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment.

The shortage of Al atoms causes a shift of the intermetallic as a\r\nwhole towards aluminum."}],"publication":"Vacuum","doi":"10.1016/j.vacuum.2023.112043","article_number":"112043","language":[{"iso":"eng"}],"publication_status":"published","date_updated":"2023-06-01T14:22:15Z","article_type":"original","intvolume":" 212","year":"2023","title":"3D-structure of intermetallic interface layer in Al–steel clad material","publication_identifier":{"issn":["0042-207X"]},"author":[{"first_name":"Michaela","last_name":"Šlapáková","full_name":"Šlapáková, Michaela"},{"full_name":"Kihoulou, Barbora","last_name":"Kihoulou","first_name":"Barbora"},{"first_name":"Jozef","last_name":"Veselý","full_name":"Veselý, Jozef"},{"first_name":"Peter","last_name":"Minárik","full_name":"Minárik, Peter"},{"full_name":"Fekete, Klaudia","first_name":"Klaudia","last_name":"Fekete"},{"first_name":"Michal","last_name":"Knapek","full_name":"Knapek, Michal"},{"first_name":"Rostislav","last_name":"Králík","full_name":"Králík, Rostislav"},{"id":"43822","last_name":"Grydin","first_name":"Olexandr","full_name":"Grydin, Olexandr"},{"full_name":"Stolbchenko, Mykhailo","first_name":"Mykhailo","last_name":"Stolbchenko"},{"full_name":"Schaper, Mirko","last_name":"Schaper","first_name":"Mirko","id":"43720"}]}]
