摘要: A low-cost and simple technique for encryption of two-dimensional patterns and shapes is suggested and demonstrated. The method is based on the superposition of random grids.关键词: Simple Lie groups Controllability Invariant vector fields Root systems ...
Forest scenes are also 3-dimensional, with the overlapping leaves of fall foliage, or a stand of aspens with cylindrical trunks receding into the distance. For such scenes, the shapes of the individual Xtra-Dimension components themselves are chosen to complement the scene. Autumn Color Reflected...
Through the good graces of Inga Karliner of the University of Illinois physics department I was put in contact with Ivan Petrov of the U of I's materials research department, which just happens to be a national collaborative center for materials testing, which means they have a hallway with ...
The active fabrics created using LCE yarns demonstrated reversible three-dimensional shape changes by utilizing circular weaving patterns that resulted in cone shapes when heated. This seamless integration of active LCE yarns with existing passive yarns opens up new possibilities for developing stimuli-resp...
Pictures can also be illusions—deceptions of vision so that what is seen does not necessarily correspond to what is physically presented. Most of visual science is now concerned with pictorial images—two-dimensional displays on computer monitors. Is vision now the science of deception?
For centuries, people knew pure carbon in two forms, diamond and graphite. Diamond is three-dimensional matrix of carbon atoms in which each atom is bonded to four others in a tetrahedral arrangement. Graphite on the other hand consists of two-dimension sheets of hexagons, like a honeycomb, ...
They are stored as a two-dimensional array of dots, which gives them a fixed resolution. A $3\times5$-inch bitmap image that prints correctly on your 300dpi laser printer will only be a $\frac{3}{4}\times1\frac{1}{4}$-inch picture if you make your final copy on a 1200dpi ...
A stick figure is a body drawn with very simple lines, and because only single lines are used, it's a two-dimensional representation. Because you are trying to capture the essence of the subject very quickly, you don't have time to draw its individual parts in any real detail. Drawing ...
Thinking Pictures: Conceptual Art from Moscow and the Baltics, exhibition view. Photo by Paco Ulman, courtesy of Kumu Art Museum. Soviet conceptual artists often worked with geometric shapes reminiscent of the Russian avant-garde, and with Kazimir Malevich’s idea of art as a spiritual substance....
Finally for this step, center align the two bodies in the design in every direction. Step 6: Cutting Out the Edge Pieces 3 More Images To begin this step, duplicate the two shapes in the design and move them together off to the side. Then take the original set of bodies and hide the...
