Hierarchical RLE Level Set: A Compact and Versatile Deformable Surface Representation BEN HOUSTON1, Exocortex Technologies, Frantic Films

This paper introduces the Hierarchical Run-Length Encoded (H-RLE) Level Set data structure. This novel data structure combines the best features of the DT-Grid (of Nielsen and Museth [2004]) and the RLE Sparse Level Set (of Houston et al. [2004]) to provide both optimal efficiency and extreme versatility. In brief, the H-RLE level set employs an RLE in a dimensionally recursive fashion. The RLE...

Set Partitioning in Hierarchical Trees

Embedded zerotree wavelet (EZW) coding, introduced by J. M. Shapiro, is a very eeective and computationally simple technique for image compression. Here we ooer an alternative explanation of the principles of its operation, so that the reasons for its excellent performance can be better understood. These principles are partial ordering by magnitude with a set partitioning sorting algorithm, ord...

Le Rle First Bezier

Transonic airfoil design problems are solved using a Genetic Algorithm (GA) based optimizer. At the desired operating point, the minimum drag and constant lift targets are achieved through either a scalarized objective function, involving an arbitrary weighting factor, or the Pareto technique. For the optimization of an airfoil at two operating points, similar approaches are used. The CPU cost ...

Single ‎A‎ssignment Capacitated Hierarchical Hub Set Covering Problem for Service Delivery Systems Over Multilevel Networks

The present study introduced a novel hierarchical hub set covering problem with capacity constraints. This study showed the significance of fixed charge costs for locating facilities, assigning hub links and designing a productivity network. The proposed model employs mixed integer programming to locate facilities and establish links between nodes according to the travel time between an origin-...
