We develop a level set method for the computation of multi-valued velocity and electric fields of one-dimensional Euler-Poisson equations. The system of these equations arises in the semiclassical approximation of SchrödingerPoisson equations and semiconductor modeling. This method uses an implicit Eulerian formulation in an extended space — called field space, which incorporates both velocity ...

This thesis describes a method for computationally recognizing the geometrical interpretation of most blades of the model of projective line geometry in geometric algebra. These different interpretations are not merely recognizable by the grade of the elements, or the absence or presence of some basis vector, as can be done for the homogeneous model for geometric algebra. GAViewer, a graphical ...

Analytical DNA ultracentrifugation revealed that eukaryotic genomes are mosaics of isochores: long DNA segments ( q 300 kb on average) relatively homogeneous in G 1 C. Important genome features are dependent on this isochore structure, e.g. genes are found predominantly in the GC-richest isochore classes. However, no reliable method is available to rigorously partition the genome sequence into ...

The general variable coefficient cylindrical/spherical KdV equation has been investigated by using the simplified homogeneous balance method. It proven that if its coefficients satisfy certain constraint conditions, then a nonlinear transformation converts solution of quadratic form into equation. admits series solutions expressed exponential functions, therefore one soliton-like and multi can ...

A form for homogeneous functions is presented which shows them to be a very simple extension of the wellknown Cobb-Douglas functions with similar properties in production (and distribution) economics. This form thus suggests new possibilities for interpreting a wide variety of empirical and theoretical results in economics; it also provides contact with developments in other fields, such as inf...

Active Learning Method (ALM) is a soft computing method which is used for modeling and control, based on fuzzy logic. Although ALM has shown that it acts well in dynamic environments, its operators cannot support it very well in complex situations due to losing data. Thus ALM can find better membership functions if more appropriate operators be chosen for it. This paper substituted two new oper...

In this article I elaborate and codify the extended case method, which deploys participant observation to locate everyday life in its extralocal and historical context. The extended case method emulates a reflexive model of science that takes as its premise the intersubjectivity of scientist and subject of study. Reflexive science valorizes intervention, process, structuration, and theory recon...
