42. Geometry In Action: Molecular Modeling Part of geometry in Action, a collection of applications of computational geometry. David Eppstein, Theory Group, ICS, UC Irvine. http://www.ics.uci.edu/~eppstein/gina/molmod.html

Molecular Modeling Connections have been growing recently between the molecular modeling community and the computational geometry. Many questions in molecular modeling can be understood geometrically in terms of arrangements of spheres in three dimensions. Problems include computing properties of such arrangements such as their volume and topology, testing intersections and collisions between molecules, finding offset surfaces (related to questions of accessability of molecule subregions to solvents such as water), data structures for computing interatomic forces and performing molecular dynamics simulations, and computer graphics algorithms for rendering molecular models accurately and efficiently (taking advantage of their special geometric structure). Classical molecular modeling has dealt with biological molecules which generally have a tree-like structure, but applications to nanotechnology require dealing with more complicated diamond-like structures; it is unclear to what extent this affects the relevant algorithms. Algorithms for finding the axis of a helix , J. Christopher, R. Swanson, and T. Baldwin. The authors use this problem to detect structural patterns in protein molecules.

Computational Mechanics Division Project: Computational Geometry. Applications to Finite Element pre- and post-processing castellano HEAD: KEYWORDS: Computational geometry - Finite elements - Mesh generation - Object-oriented programming OVERVIEW: This project assembles a set of research lines in the area of computational geometry applied to finite element processing. Tridimensional non structured mesh generation together with adaptive techniques -areas of intense activity at the present time- will receive special attention inside the project, since they are key pieces to acces the computational modelling of 3D problemas. The chance of applying computational geometry elements to calculate view factors, which are necessary to modelate heat transfer problems in radiation dominated cases, will also be explored. Other lines integrated to this project are distributed processing and results visualization in engineering STAFF: Arnica, Daniela Dari, Enzo Padra, Claudio Saliba, Roberto PROFESSIONALS FROM OTHER GROUPS INVOLVED IN THE PROJECT: Back to Computational Mechanics Division's projects page Back to Computational Mechanics Division 's home page

HB's Home Page APPLICATIONS of FRACTAL GEOMETRY Harold Brochmann In this part we attempt to answer the question: "What practical use can be made of an understanding of fractal concepts?" Smallparticles Smallparticles include dust, soot, pollen, aerosols, sand, silt, crushed minerals, the solid components of various suspensions such as paint, contaminated lubricants, etc. The physical characteristics of such particles is related in a complex way with the fractal dimension of their surfaces. For example: The tendency of soot to adhere to lung surfaces, Soot's capacity to absorb carcigenous combustion products, The opacity of paint pigment, The dullness of talc face powder, The rate of absorption of ingested pharmaceuticals, The efficiency with which crushed mineral ore can undergo refinement, The strength of objects made by cintering, ..... are all related to particle fractal dimension. Geologic Features and Structures Geologic features and structures includes mountains, coastlines, cracks and faults, valleys, river courses, silt deposition patterns, etc. The fractal dimension of geologic features and structures are related in a complex way with the conditions under which such features were formed and the processes to which they have been subjected.

One in a series of snapshots of applications of discrete mathematics to other parts of mathematics. D. A. Leonard Auburn University The Context The Problem The general decoding problem for any code, is to take a received word (that is, a corrupted code word) and produce (efficiently) the nearest code word to it (or equivalently the smallest error possible). For linear codes (subspaces), this is generally done by using functions of the received word which only depend on the error, not on the specific code word transmitted. Such functions are called syndromes For Reed-Solomon codes over , currently used in various applications such as CD technology, the syndromes are with the given received word, and a primitve element of One then uses a Berlekamp-Massey algorithm (or the extended Euclidean algorithm) to produce an error-locator polynomial (or an error-evaluator polynomial). Then one has a choice of producing all , (by viewing as a recurrence relation and the given syndromes as initial conditions) and using an inverse transform, with the (most likely) error or factoring , producing , and using Forney's formula: Algebraic-Geometric Codes Algebraic-geometric codes (the duals of those described in ``Coding Theory and Algebraic Geometry: An Interplay'') are generalizations of the Reed-Solomon codes above. As such, there should be an efficient decoding scheme that is modelled on the algorithm above. The first important algorithm in this process was the generalization of the Berlekamp-Massey algorithm to higher dimensions, published in the late 80's by Sakata. This lead to reasonably efficient vector-space based techniques, each with some flaws, either in the number of errors, number of points, or efficiency. The next important idea was published in 93 by Feng and Rao. This majority voting scheme allowed for production of more ``syndromes'' while row-reducing the syndrome matrix. Only recently has this been synthesized into a generalization of the above algorithm.

To get an idea about the style and format, take a look at the Introduction or chapter 7 on Voronoi diagrams Computational geometry Computational geometry emerged from the field of algorithms design and analysis in the late 1970s. It has grown into a recognized discipline with its own journals, conferences, and a large community of active researchers. The success of the field as a research discipline can on the one hand be explained from the beauty of the problems studied and the solutions obtained, and, on the other hand, by the many application domains-computer graphics, geographic information systems (GIS), robotics, and others-in which geometric algorithms play a fundamental role. For many geometric problems the early algorithmic solutions were either slow or difficult to understand and implement. In recent years a number of new algorithmic techniques have been developed that improved and simplified many of the previous approaches. In this textbook we have tried to make these modern algorithmic solutions accessible to a large audience. The book has been written as a textbook for a course in computational geometry, but it can also be used for self study.
