The non-orthogonal boundary-fitted coordinate transformation method is applied to the solution of steady three-dimensional conservation equations of mass, momentum, energy and speciescontinuity to obtain the laminar velocity, temperature and concentration fields for simulation of polymerization of styrene in arbitrary cross-sectional duct reactors. Variable physical properties (except for speci...

This paper reports previously obtained results concerning topographic change in a water area. Latitude-longitude components of positional data from GPS receiver were transformed to planar orthogonal coordinates, and vertical combined with depth an echo sounder. A piecewise linear function defined on triangular mesh represented surface that fitted measurement results. study applied those techniq...

Many anticounterfeiting tags rely on images intricate in different color and/or polarization states to create optical effects invisible conventional observation conditions. We build here an imaging micropolarimeter based the dual-rotating compensator system and using capabilities of cameras yield full polarimetric information for any coordinates one acquisition step. After correction camera res...

This paper describes a computational infrastructure that supports Chimera-based interfacing of different CFD solvers a body-fitted unstructured grid solver with a blockstructured adaptive cartesian grid solver to perform time-dependent adaptive movingbody CFD calculations of external aerodynamics. The goal of this infrastructure is to facilitate the use of different solvers in different parts o...

In 1916 Captain A. V. Hill was transferred from the infantry to the Ministry of Munitions to work on anti-aircraft gunnery. He determined the three-dimensional coordinates of flying objects by placing two mirrors far apart. The mirrors were viewed from a fixed distance above them and observers simultaneously marked the position of the object. He gathered brilliant men, most too old or too young...

There is usually a pattern of veins on an insect wing. This pattern is species-specific and is used taxonomically. For example, the coordinates of some characteristic points on the wing are used to compare vein patterns. The characteristic points are often vein junctions or vein ends. A tool is presented that enables automatic identification of vein junctions. An image of an insect wing is used...

We describe the reinforcement learning problem, motivate algorithms which seek an approximation to the Q function, and present new convergence results for two such algorithms.

In this paper, we address the problem of how to seamlessly and without repetition artifacts or visible projective distortion cover the surface of a polygonally-defined model with a texture pattern derived from an acquired 2D image such that the dominant orientation of the pattern will everywhere follow the surface shape in an aesthetically pleasing way. Specifically, we propose an efficient, au...
