Applying dimensional analysis to wave dispersion
(American Association of Physics Teachers, 2007-02)
We show that dimensional analysis supplemented by physical insight determines if a wave has dispersion, without recourse to sophisticated mathematical tools.
Dimensionality reduction for visualization of normal and pathological speech data
For an adequate analysis of pathological speech signals, a sizeable number of parameters is required, such as those related to jitter, shimmer and noise content. Often this kind of high-dimensional signal representation ...
ChemVA: Interactive visual analysis of chemical compound similarity in virtual screening
(IEEE Computer Society, 2021-02-13)
In the modern drug discovery process, medicinal chemists deal with the complexity of analysis of large ensembles of candidate molecules. Computational tools, such as dimensionality reduction (DR) and classification, are ...
Boundary element method for J-integral and stress intensity factor computations in three-dimensional interface cracks
A general numerical tool for the analysis of three–dimensional bimaterial interface cracks is presented in this paper. The proposed tool is based on a multidomain formulation of the Boundary Element Method (BEM), with the ...
Proteomic analysis and sperm physiopathology: The two-dimensional difference in gel electrophoresis approach
(Elsevier Science Inc., 2013-04-04)
Two-dimensional (2D) gel electrophoresis coupled with protein identification using mass spectrometry (MS) is a procedure extensively used to obtain a catalog of several thousand proteins in a single gel. These evaluations ...
Deprivation and the Dimensionality of Welfare: A Variable-Selection Cluster-Analysis Approach
We approach the problems of measuring the dimensionality of welfare and that of identifying the multidimensionally poor, by first finding the poor using the original space of attributes, and then reducing the welfare space. ...
Expectations, Satisfaction and Professional Achievement. An Analysis of their Relation in light of a New Systemic Paradigm: The Three- Dimensional Spiral of Sense
(European Center for Science Education and Research, 2017-01)
This research has been done in the field of Education, Sociology and Social and Organizational Psychology. Issues are taken up from two research studies carried out with researchers and PhDs from different disciplinary ...
Clustering biological data with SOMs: on topology preservation in non-linear dimensional reduction
(Pergamon-Elsevier Science Ltd, 2013-07)
Dimensional reduction is a widely used technique for exploratory analysis of large volume of data. In biological datasets, each object is described by a large number of variables (or dimensions) and it is crucial to perform ...
Experimental and theoretical analysis of the intensity of beams diffracted by three-dimensional photonic crystals
(American Physical Society, 2008-12)
An analysis of the diffracted beams emerging from three-dimensional photonic crystals is herein presented. The wave vectors of nonspecular beams are calculated for a triangular two-dimensional lattice and the change in ...
Boundary element analysis of three-dimensional mixed-mode thermoelastic crack problems using the interaction and energy domain integrals
(John Wiley & Sons Ltd, 2008-04)
A three-dimensional boundary element method (BEM) implementation of the interaction integral methodology for the numerical analysis of mixed-mode three-dimensional thermoelastic crack problems is presented in this paper. ...
