Since the part's final geometry is unknown until completed, it creates uncertainties for design and engineering. Existing architectural design workflows are insufficient, and industrial software packages cannot capture the complexity of self-deforming fibres to model complex fibre layups. This research introduces a feedback-based computational method conceived as four development cycles to design and evaluate fibre layups of large-scale architectural building components, and a multi-scalar digital-physical design and evaluation toolset to model and evaluate them at multiple resolutions. The universal applicability of the developed methods is showcased by two different architectural fibre structures. The results show how the systematization of methods and toolset allow for increased design flexibility and deeper integration of interdisciplinary collaborators. They constitute an important step towards a consolidated co-design methodology and demonstrate the potential to simultaneously co-evolve design and evaluation methods.", "language" : "eng", "issn" : "0926-5805", "doi" : "https://doi.org/10.1016/j.autcon.2023.104889", "bibtexKey": "ZECHMEISTER2023104889" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/215cbaa595a6eb4993ab86ab418376c26/elkepeter", "tags" : [ "IADM","Lienstromberg","MEMS","evolution","modelling","problem","quasilinear" ], "intraHash" : "15cbaa595a6eb4993ab86ab418376c26", "interHash" : "64986724c4398d14ae2c3ea8f153a653", "label" : "Well-posedness of a quasilinear evolution problem modelling MEMS with general permittivity", "user" : "elkepeter", "description" : "", "date" : "2023-03-27 11:18:04", "changeDate" : "2023-04-03 07:20:21", "count" : 4, "pub-type": "article", "journal": "J.

Therefore, in the present study, the three-dimensional deformations of the porcine urinary bladder were investigated using 10 cameras in ex vivo experiments. Voltages between 20 V and 40 V were applied to induce contraction without outflow (isovolumetric) and against different back pressures (isobaric). The fluid volume in the bladder and the fluid volume pushed out of the bladder in the active state were measured. During filling, a roughly constant pressure of 2.5\u20134 cmH2O was measured for a large volume range, followed by a steep increase. Overall, the urinary bladder shape changes from elliptical to spherical in the active phase, resulting in a more homogeneous stress field. The active pressure decreases with increasing volume, while the actively generated stress increases up to 65 kPa at the maximum volume examined. Smaller filling volumes and lower back pressures allowed complete emptying, whereas higher back pressures prevent full emptying from larger filling states. Finally, a recently developed three-dimensional model was used to describe the active and passive bladder characteristics in order to qualitatively represent the mechanical properties. Overall, this study provides for the first time a comprehensive experimental data set at organ level that leads to an improved understanding of load transfer mechanisms within the urinary bladder and serves to validate corresponding models.", "doi" : "10.1016/j.jmbbm.2022.105347", "bibtexKey": "Trostorf_2022" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/24b191d99e897e26df3f0f2cddb6083de/annettegugel", "tags" : [ "Distribution","Electric","Era","Load","Mobility.","Modelling","Planning","and","in","of","the" ], "intraHash" : "4b191d99e897e26df3f0f2cddb6083de", "interHash" : "4d116c82246d88beab7f97ce024f0fc8", "label" : "Load Modelling and Distribution Planning in the Era of Electric Mobility.", "user" : "annettegugel", "description" : "", "date" : "2022-02-14 13:26:04", "changeDate" : "2022-02-14 12:26:04", "count" : 1, "pub-type": "article", "journal": "CIRED Technical Report 2018-1", "year": "2021", "url": "", "author": [ "Kathrin Walz","Krzysztof Rudion","al. et" ], "authors": [ {"first" : "Kathrin", "last" : "Walz"}, {"first" : "Krzysztof", "last" : "Rudion"}, {"first" : "al.", "last" : "et"} ], "bibtexKey": "walz2021modelling" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/265b4f9dff8c66a01a285133f33d8b844/petraheim", "tags" : [ "2021","agent-based","amtsberg","architecture","bechert","composite","computational","density","design","itke","knippers","krtschil","menges","methods","modelling","multi-directional","multi-storey","orozco","skoury","slab","systems","timber","variable","wagner" ], "intraHash" : "65b4f9dff8c66a01a285133f33d8b844", "interHash" : "442ccbf50a181614bb7f5979b3441de5", "label" : "Design Methods for Variable Density, Multi-Directional Composite Timber Slab Systems for Multi-Storey", "user" : "petraheim", "description" : "", "date" : "2022-01-27 15:32:10", "changeDate" : "2022-01-27 14:32:10", "count" : 7, "pub-type": "inproceedings", "booktitle": "Proceedings of the 39th eCAADe Conference","publisher":"Cumincad","address":"Novi Sad", "year": "2021", "url": "http://papers.cumincad.org/cgi-bin/works/paper/ecaade2021_284", "author": [ "Luis Orozco","Anna Krtschil","Hans Jakob Wagner","Simon Bechert","Felix Amtsberg","Lior Skoury","Jan Knippers","Achim Menges" ], "authors": [ {"first" : "Luis", "last" : "Orozco"}, {"first" : "Anna", "last" : "Krtschil"}, {"first" : "Hans Jakob", "last" : "Wagner"}, {"first" : "Simon", "last" : "Bechert"}, {"first" : "Felix", "last" : "Amtsberg"}, {"first" : "Lior", "last" : "Skoury"}, {"first" : "Jan", "last" : "Knippers"}, {"first" : "Achim", "last" : "Menges"} ], "editor": [ "V Stojakovic","B Tepavcevic" ], "editors": [ {"first" : "V", "last" : "Stojakovic"}, {"first" : "B", "last" : "Tepavcevic"} ], "volume": "1","pages": "303--312","abstract": "This paper presents an agent-based method for the design of complex timber structures.

Finally, we provide a perspective on how multi-scale computational models, which couple perfusion changes to hepatic function, could become part of clinical workflows to predict and optimize patient outcome after complex liver surgery.", "file" : "Christ\\_2021\\_Hepatectomy-Induced Alterations in Hepatic Perfusion and Function - Toward Multi-Scale Computational Modeling for a Better Prediction of Post-hepatectomy Liver Function:Attachments/Christ\\_2021\\_Hepatectomy-Induced Alterations in Hepatic Perfusion and Function - Toward Multi-Scale Computational Modeling for a Better Prediction of Post-hepatectomy Liver Function.pdf:application/pdf", "doi" : "10.3389/fphys.2021.733868", "bibtexKey": "ist:Christ.21a" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/265b4f9dff8c66a01a285133f33d8b844/intcdc", "tags" : [ "agent-based","buildings","computational","construction","design","from:hansjakobwagner","itech","modelling","multi-storey","peer","robotic","rp3","rp4","timber" ], "intraHash" : "65b4f9dff8c66a01a285133f33d8b844", "interHash" : "442ccbf50a181614bb7f5979b3441de5", "label" : "Design Methods for Variable Density, Multi-Directional Composite Timber Slab Systems for Multi-Storey", "user" : "intcdc", "description" : "", "date" : "2021-09-15 14:28:23", "changeDate" : "2021-09-15 13:48:41", "count" : 7, "pub-type": "inproceedings", "booktitle": "Proceedings of the 39th eCAADe Conference","publisher":"Cumincad","address":"Novi Sad", "year": "2021", "url": "http://papers.cumincad.org/cgi-bin/works/paper/ecaade2021_284", "author": [ "Luis Orozco","Anna Krtschil","Hans Jakob Wagner","Simon Bechert","Felix Amtsberg","Lior Skoury","Jan Knippers","Achim Menges" ], "authors": [ {"first" : "Luis", "last" : "Orozco"}, {"first" : "Anna", "last" : "Krtschil"}, {"first" : "Hans Jakob", "last" : "Wagner"}, {"first" : "Simon", "last" : "Bechert"}, {"first" : "Felix", "last" : "Amtsberg"}, {"first" : "Lior", "last" : "Skoury"}, {"first" : "Jan", "last" : "Knippers"}, {"first" : "Achim", "last" : "Menges"} ], "editor": [ "V Stojakovic","B Tepavcevic" ], "editors": [ {"first" : "V", "last" : "Stojakovic"}, {"first" : "B", "last" : "Tepavcevic"} ], "volume": "1","pages": "303--312","abstract": "This paper presents an agent-based method for the design of complex timber structures. This method features a multi-level agent simulation, that relies on a feedback loop between agent systems and structural simulations that update the agent environment. Such an approach can usefully be applied for the design of variable density timber slab systems, where material arrangements based on structural, fabrication, and architectural boundary conditions are necessary. Such arrangements can lead to multi-directional spanning slabs that can accept pointwise supports in unique layouts. We discuss the implementation of such a method on the basis of the structural design of a pavilion-scale multi-storey testing setup. The presented method enables a more versatile approach to the design of multi-storey timber buildings, which should increase their applicability to a diverse range of building typologies.", "file" : ":C\\:/Users/ac128044/Google Drive/ICD_Wagner/01_Publikationen/PUBLICATION_COLLECTION/2021_ECAADE_METHODS_SLAB_DESIGN.pdf:pdf", "bibtexKey": "Orozco2021" } ] }
