This paper describes formulation and implementation of the fast multipole boundary element method (FMBEM) for 2D acoustic problems. The kernel function expansion theory is summarized, and four building blocks of the FMBEM are described in details. They are moment calculation, moment to moment translation, moment to local translation, and local to local translation. A data structure for the quad...

dyebias.application.subset Return a subset of reporters that can be dye bias-corrected reasonably well Description Convenience function returning a subset of reporters that can be expected to be corrected reasonably well. Often, the logical AND of this set and that of maW(data.norm) == 1.0 is used. The resulting subset is passed as the application.subset-argument to dyebias.apply.correction. Ar...

Local-structure scattering refinements using a simultaneous fit of x-ray/neutron total scattering, EXAFS, and diffuse scattering in electron diffraction are implemented as an extension to the RMCProfile software Version 6. Users should refer to the main RMCProfile manual for this version for details regarding RMC refinements using total scattering data alone. A user is expected to have a reason...

This paper introduces an innovative method, Dynamic Local Feature Analysis (DLFA), for human face recognition. In our proposed method, the face shape and the facial texture information are combined together by using the Local Feature Analysis (LFA) technique. The shape information is obtained by using our proposed adaptive edge detecting method that can reduce the effect on different lighting c...

I describe the challenges involved in designing and evaluating high assurance, verifiable voting systems. I describe the Pret a Voter scheme that provides voterverifiablity with minimal trust in officials, software etc. I also describe a number of threats against voting schemes and the extent to which they apply to the basic Pret a Voter scheme. Some enhancements to the scheme designed to count...

Program Slicing is a technique of identifying parts (slice) of a program that may influence or be influenced by a given set of program points (slice criteria). This technique has been extensively applied to program understanding. In the Bandera project [7], the application of program slicing was considered to reduce the size of the model extracted from concurrent Java programs for the purpose o...

Building trustworthy (dependable) systems is a major challenge faced by software developers. To this end, various fault tolerance mechanisms have been developed by researchers and used in industry. Unfortunately, more often than not these solutions ignore earlier development phases most importantly, the architecture design to exclusively focus on the implementation instead. This creates a dange...

We use the complex logarithm as a transformation for the visualization and navigation of highly complex satellite and aerial imagery. The resulting depictions show details and context with greatly different scales in one seamless image while avoiding local distortions. We motivate our approach by showing its relations to the ordinary perspective views and classical map projections. We discuss h...
