The aim of the research was to elucidate the effects of hand and massage chair massage on the biomechanical parameters of muscles of lower limbs and back, indicators of Pain Pressure Thresholds (PPT) and subjectively perceived fatigue. A total of 32 female recreational athletes (18 - 50 years old) were assigned to a hand massage, massage chair, or lying down the group. They were measured for muscle biomechanical properties (MyotonPro), PPT (Wagner Instruments) and subjectively perceived fatigue (VAS scale) before and after fatigue tests and treatment. The recovery procedure and subjective satisfaction with treatment were rated on a Likert scale. Changes in the median value of m. rectus femoris and m. gastrocnemius stiffness with treatment showed that hand massage could be more effective in reducing stiffness, as compared to chair massage. Hand massage may have benefits for recovery from physical exertion, but due to the individuality of subjects, detailed methodological studies are needed to evaluate the effects of massage chair vs. hand massage.}, language = {en} } @misc{OPUS4-3250, title = {Jahrbuch 2023/2024 der Absolventinnen und Absolventen}, editor = {Wilms, Andreas}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32507}, pages = {92}, year = {2024}, language = {de} } @misc{OPUS4-3254, title = {Forschungs- und Transferbericht der Technischen Hochschule Brandenburg 2022/23}, editor = {Wilms, Andreas and Hirsch, S{\"o}ren}, publisher = {Technische Hochschule Brandenburg}, address = {Brandenburg an der Havel}, organization = {Technische Hochschule Brandenburg}, issn = {1861-3462}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-32541}, pages = {98}, year = {2024}, language = {de} } @unpublished{TranconyWidemannLepper, author = {Tranc{\´o}n y Widemann, Baltasar and Lepper, Markus}, title = {A theory of conversion relations for prefixed units of measure}, doi = {10.48550/arXiv.2212.11580}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:522-opus4-31984}, pages = {1 -- 45}, abstract = {Units of measure with prefixes and conversion rules are given a formal semantic model in terms of categorial group theory.

PSP is the estimation of the 3D structure of a protein, generally through deep learning architectures. Information about the geometry of the protein chain has been proven to be crucial for accurate predictions of 3D structures. However, this information is usually flattened as machine learning features that are not representative of the geometric nature of the problem. Leveraging recent advances in geometric deep learning, we redesign the 3D projector part of a PSP architecture with the addition of CGENN layers . CGENNs can achieve better generalization and robustness when dealing with data that show rotational or translational invariance such as protein coordinates, which are independent of the chosen reference frame. CGENNs inputs, outputs, weights and biases are objects in the Geometric Algebra of 3D Euclidean space, i.e. G3,0,0, and hence are interpretable from a geometrical perspective. We test 6 approaches to PSP and show that CGENN layers increase the accuracy in term of GDT scores by up to 2.1\\%, with fewer trainable parameters compared to linear layers and give a clear geometric interpretation of their outputs.}, language = {en} } @inproceedings{MarkgrafDietrichMuelleretal.2023, author = {Markgraf, Klaus and Dietrich, Benjamin and M{\"u}ller, Katja and Flassig, Robert and Flassig, Peter}, title = {FINEconcepts - Wissenstransfer und Energiesystemoptimierung mithilfe des digitalen Zwillings}, series = {NWK, HS Harz, 2023}, booktitle = {NWK, HS Harz, 2023}, publisher = {HS Harz}, pages = {428 -- 435}, year = {2023}, abstract = {Climate change, but also geopolitical circumstances, are moving topics such as energy efficiency and renewable energies more and more into the focus of the population, economy , and politics.

This work describes the development and usage of a new software called FINEconcepts which creates a digital twin of an energy system. This virtual model can then be used to optimize the energy system based on annual costs, CO2 emissions or other relevant criteria such as self-sufficiency. Because all system components, which include renewable technologies as well, can be added as a building block with chosen but changeable parameters, the software allows the user to explore and awaken interest and understanding of technologies that were previously considered too costly, irrelevant, or unrealistic. Implemented projects in small and large companies as well as in residential areas did prove, that the usage of FINEconcepts leads not only to more efficient energy systems by increasing the use of renewable energy, but also increased knowledge and understanding in terms of energy. Besides economics, ecology and security, understanding is an equally important factor in achieving a sustainable energy supply.}, language = {en} } @article{WangHarthPuzyrevetal.2022, author = {Wang, Jing and Harth, Kirsten and Puzyrev, Dmitry and Stannarius, Ralf}, title = {The effect of obstacles near a silo outlet on the discharge of soft spheres}, series = {New Journal of Physics}, volume = {24}, journal = {New Journal of Physics}, publisher = {IOP}, doi = {10.1088/1367-2630/ac8bea}, year = {2022}, language = {en} } @techreport{KybaArroyoDegenetal.2024, author = {Kyba, Christopher C.M. and Arroyo, Hector Linares and Degen, Tobias and Abascal, Angela and Simoneau, Alexandre and Kuffer, Monika and H{\"o}lker, Franz and Aub{\´e}, Martin and Walczak, Ken and Espey, Brian R. and de Miguel, Alejandro S{\´a}nchez and Jechow, Andreas and Gyuk, Geza}, title = {Night Watch Mission Description Document}, publisher = {GFZ German Research Centre for Geosciences}, address = {Potsdam}, doi = {10.48440/gfz.b103-24052}, pages = {1 -- 156}, year = {2024}, abstract = {This is the Mission Description Document (MDD) for a future Earth observation satellite mission addressing visible band observations of nighttime lights.

Thereby, HR practitioners often listen to their guts feeling instead of using more systematic HR practices that are, as research evidence shows, more effective for attracting, motivating and retaining talented staff. This paper elaborates on the question how SMEs may profit from the design and implementation of evidence-based, systematic HRM instruments. The analysis focuses on the antecedents of the so called science-practitioner gap in HRM and why it is even more pronounced in SMEs as compared to larger companies. As a conclusion, we find that SMEs need to design HRM instruments that are systematic and evidence-based in their approach, but can be used by HR practitioners on an intuitive basis without ex ante training or cumbersome formal procedures. However, designing HRM instruments based on a so-called "walk-up-and-use" approach means beating new paths. Given the scarce resources for people management in SMEs, such innovative HRM instruments cannot be developed by a single SME alone. Therefore, the paradigm of open cooperation as it has been successfully applied in open source software (OSS) development is evaluated , in particular whether it can be transferred on the design of HRM instruments that take into account the specific needs of SMEs. First of all, we conceptualize a general framework how HR practitioners from SMEs and HR experts from business and academia can jointly develop Open HRM instruments. Then we discuss the social side of Open HRM, in particular why someone should contribute to Open HRM without receiving immediate profits, how to ensure the quality of openly developed HRM instruments and other gov-ernance issues. As a conclusion, we find that-despite a number of technical and social challenges that have to be overcome-Open HRM has a great potential in order to open up evidence-based HRM for SMEs.}, language = {de} } @inproceedings{OrlowskiKnauffMarquardt2025, author = {Orlowski, Maximilian and Knauff, Emilia and Marquardt, Florian}, title = {Towards Personal Assistants for Energy Processes Based on Locally Deployed LLMs}, series = {Proceedings of the 17th International Conference on Agents and Artificial Intelligence (ICAART 2025) , 2025, Porto, Portugal}, booktitle = {Proceedings of the 17th International Conference on Agents and Artificial Intelligence (ICAART 2025) , 2025, Porto, Portugal}, publisher = {SCITEPRESS}, doi = {10.5220/0013175600003890}, pages = {695 -- 706}, year = {2025}, abstract = {This paper presents a coaching assistant for network operator processes based on a Retrieval-Augmented Gen- eration (RAG) system leveraging open-source Large Language Models (LLMs) as well as Embedding Models.
