A METHOD FOR QUASI-STATIC ANALYSIS OF TOPOLOGICALLY VARIABLE LATTICE STRUCTURES
International Journal of Computational Methods, 2006The proposed time-independent quasi-static approach for simulations of lattice structures with imperfections is based on integration of the Inverse Broyden's Method suitable for finding the equilibrium state for a large system of atoms interacting through strongly nonlinear potentials and the Recursive Inverse Matrix Algorithm (RIMA) capable of ...

Neutron kinetics of fluid–fuel systems by the quasi-static method
Annals of Nuclear Energy, 2004The quasi-static method for the neutron kinetics of nuclear reactors is generalized for application to neutron multiplying systems fueled by a fluid multiplying material, typically a mixture of fissile molten salts. The method is derived by the application of factorization formulae for both the neutron density and the delayed precursor concentrations ...

Subdomain Perturbation Finite-Element Method for Quasi-static Darwin Approximation
IEEE Transactions on Magnetics, 2020The subdomain perturbation (SDP) finite-element (FE) method is a very efficient numerical technique and it speeds up the analysis of magneto- and electroquasi-static problems significantly. In order to solve quasi-static Darwin models, the authors have recently developed a low-frequency stable FE A-V formulation that incorporates both capacitive and ...

Characterisation of alginate gels using quasi-static and dynamic methods
Journal of Food Engineering, 2007Abstract The rheological behaviour of the calcium salts of several commercial mannuronic and guluronic alginates in the time and frequency domain was assessed by quasi-static (uniaxial compression and compressive stress relaxation) and oscillatory dynamic tests. Both tests gave almost the same range (1–10%) of apparent linear viscoelasticity. Use of

On-chip quasi-static floating-gate capacitance measurement method
International Conference on Microelectronic Test Structures, 1990An accurate interconnect capacitance parameter measurement technique is described. The technique is based on measurement of a capacitively divided DC voltage by means of a source follower stage integrated in the test structure. Determining of dielectric thickness as well as interconnect capacitance parameters using this technique in combination with ...

Multiphysics reactor-core simulations using the improved quasi-static method
Annals of Nuclear Energy, 2019Abstract The improved quasi-static method (IQS) is a rigorous space/time multiscale approach whereby the neutron flux is represented by a time-dependent amplitude and a time-, space-, and energy-dependent shape. The objective of the IQS factorization is to evaluate amplitude and shape on different time scales in order to reduce the computational ...

Pyroelectric Properties of Polyvinylidene Fluoride (PVDF) by Quasi Static Method
2006 IEEE International Conference on Semiconductor Electronics, 2006Our main objective is to investigate the behavior of polyvinylidene fluoride (PVDF) polymers when they are subjected to electric field in different temperature range. Initially, the PVDF powders were dissolved in acetone with different concentration and the PVDF films were then prepared by spin coating technique.

Biological cell modelling using quasi static FDTD/lumped element method
8th International Multitopic Conference, 2004. Proceedings of INMIC 2004., 2005Several numerical models have been set up in order to understand the modalities of interaction of electromagnetic (EM) fields with biological systems. This paper demonstrates the application of a quasi-static approximate version of the finite-difference time-domain method (FDTD) to modelling a biological cell, represented as a sphere inside the ...
