This paper is motivated by empirical research that has shown that increasing the angle of edge crossings reduces the negative effect of crossings on human readability. We investigate circular graph drawings (where each vertex lies on a circle) with large crossing angles. In particular, we consider the case of right angle crossing (RAC) drawings, where each crossing angle is π/2. We characterize...

this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

The liner of a compressed natural gas pressure vessel is manufactured by D.D.I. (deep drawing and ironing), which continuous process that uses deep to reduce the diameter billet ironing thickness billet. In second stage existing process, two steps have been performed separately with different dies, requires long processing time, high manufacturing cost, installation space. To solve above proble...

Deep drawing is characterized by extremely complex deformation that influenced process characteristics such as die and punch shapes, blank shape, holding force, material properties, lubrication. The optimization of the deep a challenging issue due to complicated functions define relate parameters. However, essential enhance productivity product cost in process. In this paper, MATLAB toolbox (Pa...

Abstract. In an ongoing quest to realize lighter vehicles with improved fuel efficiency, deformation characteristics of the material AA 6016 is investigated. In the first part of this study, material behavior of Al–Mg–Si sheet alloy is investigated under different process (temperature and strain rate) and loading (uniaxial and biaxial) conditions experimentally. Later, warm cylindrical cup deep...

We propose a method for visualizing a set of related metabolic pathways using 2 2D graph drawing. Interdependent, twodimensional layouts of each pathway are stacked on top of each other so that biologists get a full picture of subtle and significant differences among the pathways. Layouts are determined by a global layout of the union of all pathway-representing graphs using a variant of the pr...

deep drawing of cylindrical shapes with high limiting drawing ratio (ldr) values is relatively difficult. annealing is a further operation, which in turn adds costs and consumes significantly time to the forming process. in the present work, cylindrical cups from brass sheet were made with only limited anneal during few steps, but having ldr of 9 that is about 2 times higher than previous works...

Drawing on Henri Meschonnic’s notion of an “inscient ethics,” and putting “inscience” into dialogue with the old ideal of a “science” of translation, the article explores the collective socio-affective ecologies that organize and regulate social and professional norms and values of translation below the level of conscious awareness—as the true underlying structure not only of “subjectivity” (so...
