This so-called SSC-effect is presumably related to the active muscle stretch before shortening in SSCs. However, it remains unclear whether the stretch-induced higher preload level or stretch-induced history dependence effects maximize the SSC-effect. Therefore, we analyzed fascicle behavior, MTU shortening work, and torque/force (N=12 participants) via ultrasound and dynamometry during electrically stimulated submaximal plantar flexion contractions from 10° plantarflexion to 15° dorsiflexion. To elucidate the effects of preload level and preload modality (i.e. contraction type) on shortening performance, muscle-tendon unit shortening was preceded by fixed-end (SHO), active stretch (SSC), and preload-matched fixed-end (MATCHED) contractions. Prior to shortening MATCHED and SCC had the same preload level (1% torque difference), similar joint position and muscle fascicle lengths. Compared with SHO, shortening work was significantly (p<.001, partial η2=.749) increased by 85% and 55% for SSC and MATCHED, respectively, with SSC shortening work being significantly higher than MATCHED (p=.016). This indicates that preload contributes by 65% to the overall SSC-effect, so that 35 % need to be referred to stretched-induced history dependent mechanisms. Additionally, SSC showed larger fascicle forces at the end of shortening (p<.001) and 20% less depressed isometric torque following shortening compared with MATCHED (p<.001). Since potential decoupling effects by the series elastic element were controlled by matching the preload levels, we conclude that the difference between SSC and MATCHED is related to stretch-induced long-lasting history dependent effects.", "language" : "English", "issn" : "1522-1601", "doi" : "10.1152/japplphysiol.00809.2023", "bibtexKey": "Goecking_2024" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2d810c9a4b4782d6fdb37e29a549a0007/annettegugel", "tags" : [ "350","Applied","Large","MVA","Monitoring","ODAF\u2013Cooled","Power","Thermal","Transformers","Unit" ], "intraHash" : "d810c9a4b4782d6fdb37e29a549a0007", "interHash" : "7694a309dcdcdb89e56ca770c55dbfe4", "label" : "New Approach in Thermal Monitoring of Large Power Transformers Applied on a 350 MVA ODAF\u2013Cooled Unit", "user" : "annettegugel", "description" : "", "date" : "2020-08-10 13:55:45", "changeDate" : "2020-08-10 11:55:45", "count" : 1, "pub-type": "proceedings", "year": "2004", "url": "https://www.ieh.uni-stuttgart.de/dokumente/publikationen/2004_aptadm_cardillo.pdf", "author": [ "Enzo Cardillo","Kurt Feser" ], "authors": [ {"first" : "Enzo", "last" : "Cardillo"}, {"first" : "Kurt", "last" : "Feser"} ], "eventtitle" : "APTADM 2004", "venue" : "Wroclaw, Poland", "eventdate" : "September 15-17", "bibtexKey": "cardillo2004approach" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/253563f59d2a196336ef9eb70e91036c7/itke", "tags" : [ "biomat","dahy","soft_xr","petrs","robotic","2018","itke","unit","from:petraheim","sippach","explorer" ], "intraHash" : "53563f59d2a196336ef9eb70e91036c7", "interHash" : "3f659b408627ef2ea292b4b8776caec2", "label" : "Soft_XR \u2013 Soft Robotic Explorer Unit", "user" : "itke", "description" : "", "date" : "2020-05-22 14:22:38", "changeDate" : "2020-05-22 12:22:38", "count" : 2, "pub-type": "inproceedings", "booktitle": "Proceedings of the 1st Conference of Design Computing 2018","address":"Prague, Czech Republique", "year": "201ß", "url": "", "author": [ "Timo Sippach","Jan Petrs","Hanaa Dahy" ], "authors": [ {"first" : "Timo", "last" : "Sippach"}, {"first" : "Jan", "last" : "Petrs"}, {"first" : "Hanaa", "last" : "Dahy"} ], "language" : "eng", "bibtexKey": "sippach201sssoftxr" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/253563f59d2a196336ef9eb70e91036c7/petraheim", "tags" : [ "2018","biomat","dahy","explorer","itke","petrs","robotic","sippach","soft_xr","unit" ], "intraHash" : "53563f59d2a196336ef9eb70e91036c7", "interHash" : "3f659b408627ef2ea292b4b8776caec2", "label" : "Soft_XR \u2013 Soft Robotic Explorer Unit", "user" : "petraheim", "description" : "", "date" : "2020-05-20 13:12:39", "changeDate" : "2020-06-02 10:07:21", "count" : 2, "pub-type": "inproceedings", "booktitle": "Proceedings of the 1st Conference of Design Computing 2018","address":"Prague, Czech Republique", "year": "201ß", "url": "", "author": [ "Timo Sippach","Jan Petrs","Hanaa Dahy" ], "authors": [ {"first" : "Timo", "last" : "Sippach"}, {"first" : "Jan", "last" : "Petrs"}, {"first" : "Hanaa", "last" : "Dahy"} ], "language" : "eng", "bibtexKey": "sippach201sssoftxr" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2ce0df7291d15f3b0f1467222f3958c4d/amerwafai", "tags" : [ "Architecture","CUDA","Compute","Device","GPU","Graphics","HLRS","Processing","SCOPE","Unified","Unit","myown" ], "intraHash" : "ce0df7291d15f3b0f1467222f3958c4d", "interHash" : "782fe775e19c904f41d1b5e185f207f1", "label" : "Sparse matrix vector multiplications on graphic processors", "user" : "amerwafai", "description" : "", "date" : "2016-01-29 09:34:55", "changeDate" : "2016-01-29 08:39:18", "count" : 1, "pub-type": "mastersthesis", "address":"Nobelstr. 19, 70569, Stuttgart", "year": "2009", "url": "", "author": [ "Mhd.

Intel processors are now coming with double or even quad cores like Xeon processor. Graphics Processing Units (GPUs) are considered to be highly parallel multi-core processors with tremendous performance. They are specially designed to deal with 3D and realtime graphics. And after the introduction of the new API, Compute Unified Device Architecture (CUDA), from NVIDA, the GPU became an attractive choice for general purpose parallel computing to solve many complex numerical problems. \r\nSparse Matrix-Vector (SpMV) multiplication is one of the most important kernels in scientific computing. Its sparsity, irregularity and indirect addressing properties present new challenges to map it to multi-core systems. \r\nThe objective of this work is to analyze the speed of execution of SpMV multiplication on NVIDIA GPUs (Tesla C1060). An algorithm based on a tailored version of ELLPACK, called Aligned-ELLPACK-R, as well as different algorithms have been developed using different storage formats. These implementations are done using the programming language CUDA. Finally the comparison of that performance has been done with respect to different implementations of SpMV on Intel Xeon E5560 processor using Jagged Diagonal Formats (JAD), ELLPACK and ELLPACK-R storage formats. \r\nThe results show the superiority of JAD storage format over the matrices used to test SpMV on conventional super scaler processors. SpMV on Tesla C1060 based on Aligned-ELLPACK-R outperforms the fastest implementation on CPU with speedup factor 13 times. It also outperforms the CUDA library based on ELLPACK with 2.3 speedup factor.", "date-added" : "2015-08-18 13:53:17 +0000", "date-modified" : "2015-08-18 14:02:15 +0000", "bibtexKey": "wafai09" } ] }
