Prevention of Partial Draw-In During High Speed Deep Drawing
Key Engineering Materials, 2009Due to an ongoing trend of function compaction miniaturization gets more and more important in industrial production. Through the growing miniaturization new difficulties have overcome like scaling effects. However, on the other hand scaling towards smaller parts enables the application of new technologies which do not work in macro engineering.

Edge Detection in Natural Scenes Inspired by the Speed Drawing Challenge
International Journal of Image and Graphics, 2021Edge detection is a major step in several computer vision applications. Edges define the shape of objects to be used in a recognition system, for example. In this work, we introduce an approach to edge detection inspired by a challenge for artists: the Speed Drawing Challenge.

Predicting fracture in high-speed wire drawing
Strength of Materials, 19811. A mathematical model of wire drawing speed was constructed, with allowance for inertial terms and the angle of taper, from the theory of viscoplastic flow. The stresses and temperature inside the deformation zone were determined. 2. The model makes it possible to find the critical drawing speeds corresponding to brittle and ductile ...

Lubricating and cooling liquids for high-speed drawing
Vestnik Mashinostroeniya, 2022The features of the effect of the lubricating-cooling liquid (LCL) on the cutting process during high-speed drawing of the external shaped surfaces are considered. Criteria and recommendations for the selection of coolants for highspeed drawing of workpieces from structural steels are given.

Speed Up Graph Drawing for Social Network Visualization
2011Though classical forced-directed algorithms have many advantages on graph drawing, such as good-quality results, flexibility, simplicity, etc., the high running time makes them impractical to real applications. To this end, we propose a community-based approach to speed up graph drawing for social networks under the assumption that the position of a ...

High-speed drawing of steel wire
Steel in Translation, 2013The increase in productivity due to increase in the drawing speed may be largely lost as a result of more frequent shutdown of the equipment associated with the replacement of worn dies and with wire fracture. The influence of the tool parameters on its wear and the wire fracture is analyzed.

High‐speed transformation of drawing images based on structure description
Systems and Computers in Japan, 1987AbstractThis paper assumes the situation where the existing drawing is to be re‐utilized after a partial modification, and discusses a system, which can easily improve or modify with a high speed the characters and figures at the image level. First, the input drawing is segmented automatically and described in terms of the composing elements of the ...

Circle-Drawing Movements at Different Speeds: Role of Inertial Anisotropy
Journal of Neurophysiology, 2002This study investigated the role of inertial anisotropy at the hand in causing distortions in movement. Subjects drew circles in the horizontal plane at four locations in the workspace at three instructed paces using elbow and shoulder movements.

Adjustable speed D-C drives for deep-draw presses
Transactions of the American Institute of Electrical Engineers, Part II: Applications and Industry, 1953The trend in the automobile industry toward larger and more complex stamped parts for fabricating automobile bodies has necessitated radical changes in the design of stamping presses and their associated drives. The drive problems presented by these more complex machines and operations have led to the development of new drive systems.

Speed, subjectivity and visual conventions in ethnographic reportage drawings
Drawing: Research, Theory, Practice, 2021Reportage drawing is a way of visual journalism and records opinions as well as observation. In ethnographic fieldwork, reportage drawing has been used as a method of visually documenting ethnographic discoveries. The question is: what are the most significant skills that a reportage drawing artist need to effectively document visual materials?
