Systematic Derivation (systematic + derivation)
Selected AbstractsSystematic derivation of an asymptotic model for the dynamics of curved viscous fibersMATHEMATICAL METHODS IN THE APPLIED SCIENCES, Issue 10 2008Satyananda Panda Abstract This paper presents a slender body theory for the dynamics of a curved inertial viscous Newtonian fiber. Neglecting surface tension and temperature dependence, the fiber flow is modeled as a three-dimensional free boundary value problem in terms of instationary incompressible Navier,Stokes equations. From regular asymptotic expansions in powers of the slenderness parameter, leading-order balance laws for mass (cross-section) and momentum are derived that combine the unrestricted motion of the fiber centerline with the inner viscous transport. The physically reasonable form of the one-dimensional fiber model results thereby from the introduction of the intrinsic velocity that characterizes the convective terms. For the numerical investigation of the viscous, gravitational and rotational effects on the fiber dynamics, a finite volume approach on a staggered grid with implicit upwind flux discretization is applied.

[source] Equivalent circuit representation for integral formulations of electromagnetic problemsINTERNATIONAL JOURNAL OF NUMERICAL MODELLING: ELECTRONIC NETWORKS, DEVICES AND FIELDS, Issue 1 2002H. Baudrand The purpose of this study is to investigate the resources offered by electromagnetic equivalent circuits as a tool for the systematic derivation of integral equations and also, to propose consistent models for active sources.

[source] Advanced relationships between categories analysis as a qualitative research toolJOURNAL OF CLINICAL PSYCHOLOGY, Issue 7 2010Merav Rabinovich Abstract The authors propose an advanced relationships between categories (RBC) model as an expansion of Tutty, Rothery, and Grinnell's (1996) qualitative tool for classifying RBC patterns as contained, temporal, and causal relationships. It is assumed that identification of the relationships obtained among categories of qualitative data paves the way for construction of a theory, even though few tools have been developed for this purpose to date. The advanced RBC model points to three additional relationship patterns: bilateral, trilateral, and quadrilateral relationships. These relationships reveal how the text itself links among its various components. The model serves as an innovative tool for systematic derivation of explanations based on the qualitative raw data, contributing to grounded theory and other interpretive studies. © 2010 Wiley Periodicals, Inc.

[source] A Unified Dynamic Model Formulation for Robotic Manipulator SystemsJOURNAL OF FIELD ROBOTICS (FORMERLY JOURNAL OF ROBOTIC SYSTEMS), Issue 10 2003Anjan Kumar Swain This paper addresses the problem of the formulation of a unified dynamic model for sundry robotic manipulator systems derived from the first principle of mechanics instead of the existing formulation based on linear separability principle. It provides a systematic derivation, evaluation, and subsequent conceptual interpretation of manipulator dynamics model. Further, it analyzes the generality of the unified model over a wide range of manipulator configurations. In addition, it describes the implementation aspects of the unified model. © 2003 Wiley Periodicals, Inc. [source] | ||||||||||
