PERFORMANCE OF IRANIAN CHILDREN ON THE DRAW-A-MAN TEST

In this study, the Draw-A-Man Test was administered to 183 Iranian children, 96 boys and 87 girls from age of 36 to 119.5 months. The subjects were selected randomly from middle-class families in Tehran. The results show that younger Iranian children scored higher than the older ones. In addition to the age differential on performance, sex differences on drawing a man were tested by means ...

Fiber draw synthesis

The synthesis of a high-melting temperature semiconductor in a low-temperature fiber drawing process is demonstrated, substantially expanding the set of materials that can be incorporated into fibers. Reagents in the solid state are arranged in proximate domains within a fiber preform. The preform is fluidized at elevated temperatures and drawn into fiber, reducing the lateral dimensions and br...

How to Draw Tropical Planes

The tropical Grassmannian parameterizes tropicalizations of ordinary linear spaces, while the Dressian parameterizes all tropical linear spaces in TP. We study these parameter spaces and we compute them explicitly for n ≤ 7. Planes are identified with matroid subdivisions and with arrangements of trees. These representations are then used to draw pictures.

How to Draw a Planarization

In this thesis we study the problem of computing a straight-line representation of a planarization with a fixed combinatorial structure. By the results of Mnëv [Mnë88] and Shor [Sho91] this problem is as hard as the Existential Theory of the Reals (∃R-Complete). We present a heuristic called Geometric Planarization Drawing to compute a straight-line representation of a planarization. We take an...
