307 Tasdizen, Tolga; Whitaker, Ross T.; Marc, Robert E.; Jones, Bryan W.Enhancement of cell boundaries in transmission electon microscopy imagesTransmission electron microscopy (TEM) is an important modality for the analysis of cellular structures in neurobiology. The computational analysis of neurons entail their segmentation and reconstruction from TEM images. This problem is complicated by the heavily textured nature of cellular TEM ima...2005
308 Mathews, V. JohnIdentification of nonlinear, memoryless systems using chebyshev nodesABSTRACT This paper describes an approach for identification of static nonlinearities from input-output measurements. The approach is based on minimax approximation of memoryless nonlinear systems using Chebyshev polynomials. For memoryless nonlinear systems that are finite and continuous with fini...2005
309 Stevens, KennethModeling and verifying circuits using generalized relative timingWe propose a novel technique for modeling and verifying timed circuits based on the notion of generalized relative timing. Generalized relative timing constraints can express not just a relative ordering between events, but also some forms of metric timing constraints. Circuits modeled using gener...2005

Statistical segmentation algorithms compute these quantitative results, yet volume rendering tools typically produce only qualitative imagery via transfer functionbase...2005
311 Furse, Cynthia M.Commission B (fields and waves) international survey about EM educationCommission B has the terms of reference "Fields and waves", which have been well established on the basis of electromagnetism and Maxwell's equations.

312 Furse, Cynthia M.Noise-domain reflectometry for locating wiring faultsAbstract-Reflectometry is commonly used to determine the integrity of cables and wiring. This paper describes a new family of reflectometers, the noise-domain reflectometers (NDR), that uses existing data signals on wiring and does not need to generate any signals of their own. There are two types o...2005
313 Tasdizen, Tolga; Whitaker, Ross T.A geometric multigrid approach to solving the 2D inhomogeneous laplace equation with internal drichlet boundary conditionsThe inhomogeneous Laplace (Poisson) equation with internal Dirichlet boundary conditions has recently appeared in several applications to image processing and analysis. Although these approaches have demonstrated quality results, the computational burden of solution demands an efficient solver. Desi...2005
