The potential of adaptive structures is based on the principle of providing means for the system to accommodate a variety of loading conditions (earthquakes, wind, snow) by actively inducing deformations and forces in response to external loads. Thus, stresses and vibrations in the structure are reduced, maintaining or exceeding the performance of passive structures while using much less material and, correspondingly, resources. Adaptive structures, in comparison to traditional systems, contain sensors, actuators, and control systems. One method of actuation is the controlled positioning of the support points of structures. Assuming a statically indeterminate structure, the displacement of the supports will introduce structural deformations and forces. For three-dimensional structures such as the double-curved shell structure under investigation, translational positioning of the support must be provided in all directions. One method to achieve this is the use of 3-SPR-parallel mechanism. The implementation requires a unique and real time solution of the forward and inverse kinematics of the mechanism in order to relate actual displacement of the structural support of the shell to the displacement of the actuators. The solution presented here is based on an analytical approach taking into account the constraint conditions of the 3-SPR-parallel mechanism. The method is validated by numerical analysis of the workspace and then implemented on a reference system.", "doi" : "10.1109/AIM.2013.6584279", "bibtexKey": "worner_kinematic_2013" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2ec952595ff449504c1022011ebc3d996/tourian", "tags" : [ "ERA,","analysis","decomposition,","error","estimates,","evaluation,","geoinst","imported","multi-scale","precipitation","statistical" ], "intraHash" : "ec952595ff449504c1022011ebc3d996", "interHash" : "864577af10785fbb6ed1ad6c31ba06e2", "label" : "Evaluating the Evolution of ECMWF Precipitation Products Using Observational Data for Iran: From ERA40 to ERA5", "user" : "tourian", "description" : "", "date" : "2022-11-28 10:28:12", "changeDate" : "2025-11-30 22:22:14", "count" : 2, "pub-type": "article", "journal": "Earth and Space Science", "year": "2022", "url": "https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2022EA002352", "author": [ "Navid Ghajarnia","Mahdi Akbari","Peyman Saemian","Mohammad Reza Ehsani","Seyed-Mohammad Hosseini-Moghari","Asghar Azizian","Zahra Kalantari","Ali Behrangi","Mohammad J.

Studies evaluating the performance of individual ERA products cannot adequately assess the evolution of the products. We compared the performance of all ERA precipitation products at daily, monthly, and annual data (1980\u20132018) using more than 2100 Iran precipitation gauges. Results indicated that ERA-40 performed worst, followed by ERA-20CM, which showed only minor improvements over ERA-40. ERA-20C considerably outperformed its predecessors, benefiting from the assimilation of observational data. Although several previous studies have reported full superiority of ERA5 over ERA-Interim, our results revealed several shortcomings in ERA5 compared with the ERA-Interim estimates. Both ERA-Interim and ERA5 performed best overall, with ERA-Interim showing better statistical and categorical skill scores, and ERA5 performing better in estimating extreme precipitations. These results suggest that the accuracy of ERA precipitation products has improved from ERA-40 to ERA-Interim, but not consistently from ERA-Interim to ERA5. This study employed a grid-grid comparison approach by first creating a gridded reference data set through the spatial aggregation of point source observations, however, the results from a point-grid approach showed no change in the overall ranking of products (despite the slight changes in the error index values). These findings are useful for model development at a global scale and for hydrological applications in Iran.", "eprint" : "https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/2022EA002352", "doi" : "https://doi.org/10.1029/2022EA002352", "bibtexKey": "https://doi.org/10.1029/2022EA002352" } , { "type" : "Publication", "id" : "https://puma.ub.uni-stuttgart.de/bibtex/2af9cf6633cb0a8ba281c9a520a2aee04/annettegugel", "tags" : [ "Analysis","Assessment","Frequency","Measurements","Methods","Power","Response","Statistical","Transformer" ], "intraHash" : "af9cf6633cb0a8ba281c9a520a2aee04", "interHash" : "49ce555523be57fe289eb6e8235a1dad", "label" : "Analysis of Statistical Methods for Assessment of Power Transformer Frequency Response Measurements", "user" : "annettegugel", "description" : "", "date" : "2021-01-21 16:12:13", "changeDate" : "2021-01-21 15:12:13", "count" : 1, "pub-type": "article", "year": "2020", "url": "", "author": [ "Mehran Tahir","Stefan Tenbohlen","S.
