Doublecloth: History, Technique, Possibilities.

Merged with duplicate record 10026.1/2320 on 06.20.2017 by CS (TIS)The aim of this research is to analyse through practical and historical investigation the manner in which Doublecloth in the twentieth century has been transformed from a traditional woven technique to one of artistic innovation and challenge. The first series of woven samples and historic enquiry concerns the structure and pattern of doublecloth at a time when its industrial and craft-based use was for the production of decorative and utilitarian woven fabrics. The research focuses on the extent to which this technique was given aesthetic credibility by its altered profile at the Bauhaus and the subsequent influence of the writings and work of Anni Albers. While the philosophy and products of the Bauhaus and the role of Walter Gropius have been documented and widely debated the practice of textiles, and the influence on it of gender, class and the hierarchical practice of craft, has received little critical attention. The research seeks to redress this imbalance, evaluating why the output of the textile workshops was undervalued artistically and considered marginal to the products from other workshops. This leads to a consideration of the interface between the practice of Fine Art and the practice of Craft, between designing and making, between art and industry. The woven samples are a process of experimentation against which the historic stages can be tested and the technical constraints of contemporary practice can be explained. This primary material leads to a consideration of the new technology and the impact of Nuno doublecloth fabrics on the production of doublecloth for the mass market. The evidence suggests that while new fabric finishes and experimental pattern effects are desirable, the difficulties of hand production are so prohibitive, that it is only with computer aided technology that such ambitions can be me

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
