Solution of the distributional equation and Green’s functions for scattering problems [PDF]

open access: yes, 2007
A general method is described to obtain Green’s functions involved in nuclear scattering theory problems. By imposing specified boundary conditions on the general solution to the distribution equation, one can readily obtain the Green’s function for the ...

Efficient analysis of input impedance and mutual coupling of microstrip antennas mounted on large coated cylinders [PDF]

open access: yes, 2003
Cataloged from PDF version of article.An efficient and accurate hybrid method, based on the combination of the method of moments (MoM) with a special Green’s function in the space domain is presented to analyze antennas and array elements conformal to

Response functions for electrically coupled neuronal network : a method of local point matching and its applications [PDF]

open access: yes, 2016
Neuronal networks connected by electrical synapses, also referred to as gap junctions, are present throughout the entire central nervous system. Many instances of gap-junctional coupling are formed between dendritic arbours of individual cells, and these

Computer programs for temperature in fins and slab bodies with the method of Green's functions

open access: yesComputer Applications in Engineering Education, 2004
AbstractHeat conduction in fins and slab bodies, a traditional undergraduate topic, is treated with the Green's function (GF) method. A variety of boundary conditions and heating conditions are included. Computer programs are described which are designed to improve student learning of the GF method. The programs are available from the author.

Steady-Periodic Green’s Functions and Thermal-Measurement Applications in Rectangular Coordinates

open access: yesHeat Transfer, Part B, 2005
Two-dimensional steady-periodic heat transfer in rectangles, slabs, and semi-infinite bodies is treated with the method of Green’s functions. The application is the measurement of thermal properties. Several types of boundary conditions are treated systematically, including convection conditions and boundaries containing a thin, high-conductivity film.

Green’s Functions for Surface Waves in a Generic Velocity Structure [PDF]

open access: yes, 2014
Methodologies for calculating surface‐wave velocities and the associated displacement/stress eigenfunctions and Green’s functions have been well established for many decades. However, to our knowledge, no one has ever documented a quantitative evaluation

A New Role of Green′s Function in Interpolation and Sampling Theory

open access: yesJournal of Mathematical Analysis and Applications, 1993
AbstractOne of the most fundamental theorems in interpolation and sampling theory is the Whittaker-Shannon-Kotel′nikov sampling theorem, which gives an algorithm for reconstructing functions that are Fourier transforms of functions with compact supports, from their sampled values at a discrete set of points.

Cylindrically symmetric Green’s function approach for modeling the crystal growth morphology of ice [PDF]

open access: yes, 1999
We describe a front-tracking Green’s function approach to modeling cylindrically symmetric crystal growth. This method is simple to implement, and with little computer power can adequately model a wide range of physical situations. We apply the method to

A comparison of simple methods to incorporate material temperature dependency in the Green’s function method for estimating transient thermal stresses in thick-walled power plant components [PDF]

open access: yes, 2016
The threat of thermal fatigue is an increasing concern for thermal power plant operators due to the increasing tendency to adopt “two-shifting” operating procedures.
