The precision of image synthesis techniques for rendering naturalistic scenes often works contrary to the realism of the everyday world. Pristine, crystalline, uniform and perfect may describe the most idealized computer images: the surfaces are smooth, neat and crisp in appearance. Efforts to produce realism have recently focused on light and the interaction of light with surfaces. The radiosi...

PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...

In Chapter 1, we seek to understand the relation between liquidity and market imperfections from two dimensions: 1) Across liquidity measures, we compare the influence of imperfections on two commonly used measures, Kyle's lambda and price reversal; 2) Across imperfections, we study the interaction between two sources of market imperfection, information asymmetry and participation cost. We show...

In many different industries, such as chemical industry, plastic industry and especially in rubber industry, there are systems with random parameters. It is well-known in case of the systems with determined parameters that the systems can be either stable or unstable. But, in case of the random parameters the systems can be stable, unstable, or stable with some probability. The stability proble...
