h‐plots for displaying nonmetric dissimilarity matrices [PDF]

open access: greenStatistical Analysis and Data Mining: The ASA Data Science Journal, 2013
AbstractNonmetric pairwise data with violations of symmetry, reflexivity, or triangle inequality appear in fields such as image matching, web mining, or cognitive psychology. When data are inherently nonmetric, we should not enforce metricity as real information could be lost. The multidimensional scaling problem is addressed from a new perspective.

Synthesis, structural, W-H plot and size-strain analysis of nano cobalt doped MgFe2O4 ferrite [PDF]

open access: diamondScience of Sintering, 2020
In this study we have investigated structural attribute of Co+2 doped MgFe2O4. Synthesis of Mg1-xCoxFe2O4 ferrite was carried out using co-precipitation method. The formation of spinal ferrite was confirmed through X-ray diffraction.

Detección gráfica de la multicolinealidad mediante el h-plot de la inversa de la matriz de correlaciones [PDF]

open access: greenRevista Colombiana de Estadística, 2005
La multicolinealidad origina imprecisión en los estimadores de los coeficientes de un modelo lineal. En este trabajo proponemos un gráfico basado en la representación h-plot de la inversa de la matriz de correlaciones, que permite visualizar con cierto ...

Characterization of Zinc oxide & Aluminum Ferrite and Simulation studies of M-H plots of Cobalt/Cobaltoxide

open access: green, 2017
Zinc oxide and Aluminum Ferrite were prepared Chemical route. The samples were characterized by XRD and VSM. Simulation of M-H plots of Co/CoO thin films were performed. Effect of parameters was observed on saturation magnetization.

Analysis of the possible helical structures of nucleic acids and polynucleotides. Application of (n-h) plots. [PDF]

open access: greenNucleic Acids Research, 1976
The two helical parameters n and h where n is the number of nucleotide residues per turn and h is the height per nucleotide residue have been evaluated for single stranded helical polynucleotide chains comprising C(3') -endo and C(2') endo class of nucleotides. The helical parameters are found to be especially sensitive to the C(4')-C(3') (sugar pucker)

Magnetic-head positioning control of HDDs with improved H∞ controller by Robust Controller Bode (RCBode) plot

open access: goldJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2018
In this paper, we present a robust controller design method for a magnetic-head positioning system in a hard disk drive (HDD) based on the H∞ control theory and the Robust Controller Bode (RCBode) plot.

MULTICOLINEARITY DETECTION BY MEANS OF THE h-PLOT OF THE CORRELATION MATRIX INVERSE DETECCIÓN GRÁFICA DE LA MULTICOLINEALIDAD MEDIANTE EL H-PLOT DE LA INVERSA DE LA MATRIZ DE CORRELACIONES

open access: yesRevista Colombiana de Estadística, 2005
Multicollinearity generates imprecision in the estimates of the coefficients in linear models. We propose to use the h-plot of the inverse of the correlation matrix to obtain a representation of the linear relations between the predictor variables.

Synthesis, characterization and microstructural evaluation of ZnO nanoparticles by William-Hall and size-strain plot methods

open access: yesBulletin of the Chemical Society of Ethiopia, 2022
. At various calcination temperatures 450, 550 and 650 °C, zinc oxide nanoparticles were produced. Calcinated ZnO has high surface area as the BET was 119.12 m2g–1 and the average particle radius was calculated to be 1.16 nm.
