Limiting disproportionate disaccommodation in design for human variability
Ergonomics, 2013In the design of artefacts, tasks and environments for human use, the body dimensions of the target population are a critical element in spatial optimisation of the design. This study examines how the choices designers make affect the ability of different user groups to safely and effectively interact with a designed artefact. Due to the variability in

Data processing for magnetic disaccommodation spectroscopy
IEEE Transactions on Magnetics, 1989The authors address the problems of analyzing experimental data obtained from magnetic disaccommodation measurements in order to extract information about the nature of the underlying phenomena. Some data processing methods commonly used in this type of investigation are reviewed, and novel techniques aimed at the optimization of the signal-to-noise ...

Mechanism of Disaccommodation in Ferrite
Journal of the Physical Society of Japan, 1962The time decrease of the magnetic permeability after demagnetization, so called disaccommodation, was observed for Ni–Zn ferrite, which had various degrees of oxidation. The effect of the existence of Fe 2+ ion in disaccommodation was detected. Fe 2+ facilitates the diffusion of cation and makes the disaccommodation rapid.

Mechanism of Disaccommodation in Ferrites
Journal of the Physical Society of Japan, 1962Theory and experimental techniques developed in the study of the uniaxial anisotropy in iron-cobalt ferrites have been applied to the disaccommodation phenomena in ferrites. The results have shown clearly and quantitatively that the underlying mechanisms are essentially the same in these two phenomena, i.e., process of reorientation of the ionic ...

Magnetic disaccommodation of hydrogen and dislocations in metals
Il Nuovo Cimento B Series 11, 1976In ferromagnetic materials hydrogen has been observed to give rise to three types of magnetic relaxations: 1) diffusion aftereffect due to a long-range migration of hydrogen within domain walls, 2) orientation after-effect due to the rearrangement of anisotropic hydrogen-impurity complexes, 3) magnetic cold-work peak resulting from a condensed hydrogen

Magnetic disaccommodation in normal spinel structures
Applied Physics A Solids and Surfaces, 1991Magnetic disaccommodation is investigated for ferrous ferrites with normal spinel structure. This study shows the presence of a new relaxation process in the temperature region IV (≃285 K) that has not been detected in inverse spinels. A numerical analysis of the isochronal spectra reveals that it is composed of two simple Debye processes with ...

Magnetic disaccommodation in Sn substituted magnetite
Journal of Magnetism and Magnetic Materials, 2001Abstract The relaxation of the initial magnetic permeability has been measured in polycrystalline Sn-doped magnetite with nominal composition Sn x Fe 3− x O 4 with x ranging from x =0 to 0.6. In the temperature range between 80 and 500 K, the time decay of the initial permeability after sample demagnetization has been represented by means of ...

On the Mechanism of Disaccommodation in Ferrites
Journal of the Physical Society of Japan, 1962The dependence of the disaccommodation spectra on the density of cation vacancies has been investigated in the manganese- and nickel-iron-rich ferrites and the results compared with the dependence predicted by Iida (1) . It is found that his model is not applicable to the disaccommodation effect occurring at room temperature.

Disaccommodation measurements in amorphous wires
Journal of Magnetism and Magnetic Materials, 1992 Abstract Stress dependent magnetic disaccommodation is studied for high and low magnetostrictive amorphous wires and ribbons. The results are interpreted considering the particular domain structure developed in amorphous wires during preparation.
