Due to the complexity of the structures, their modeling and simulation needs to be solved in three-dimensional (3D) CAD developments. In this paper, 3D loop geometrical models of weft knitted fancy structures, including tuck stitch, jacquard stitch, transfer stitch and fleecy stitch, were developed based on an improved model of plain loop, and their central axes as some 3D space curves were achieved by using Non-Uniform Rational B-Splines (NURBS). The 3D visual simulation programme was written in C++ programming language using OpenGL, which was a function library of 3D graphics. Some examples of weft knitted fancy fabrics were generated and practical application of 3D simulation was discussed.展开更多

The story revolves around a sack of gold that every one of the 19 principal citizens in the"most honest and upright town"Hadleyburg desires to claim by any means, fair or foul. The vivid description reveals the bourgeois hypocrisy of the capitalist society. This article intends to study the story from the perspective of binary opposition and finds out three pairs of opposition, they are honesty vs. hypocrisy; trust vs. trap; fancy vs. fact, which makes the story more sarcastic and full of sight and wisdom.展开更多
