First-order reversal curve (FORC) diagrams of magnetic mixtures: Micromagnetic models and measurements

Physics of the Earth and Planetary Interiors, 2006
First-order reversal curve (FORC) diagrams were modelled and experimentally measured for different assemblages of single-domain (SD) magnetite particles with bimodal distributions of coercivities, and varying concentrations.

Magnetic vortex effects on first-order reversal curve (FORC) diagrams for greigite dispersions [PDF]

Earth and Planetary Science Letters, 2018
First-order reversal curve (FORC) diagrams are used increasingly in geophysics for magnetic domain state identification. The domain state of a magnetic particle is highly sensitive to particle size, about which FORC diagrams provide valuable information.

Scale diagrams for forced plumes

Journal of Fluid Mechanics, 1973
A wide range of behaviour for turbulent forced plumes generated by vertical emission of heated or other buoyant fluid from finite sources in extensive and otherwise still uniform environments can be represented on a single non-dimensional diagram of characteristic heights, plotted against a parameter Γ, which for forced plumes represents the balance of

Form as Diagram of Forces

Journal of Architectural Education, 2003
Abstract The relationships between form, performance, and construction are uniquely demonstrated in the long-span works of Pier Luigi Nervi. The balance of these forces led in Nervi's case to a series of works that take the form of the equiangular spiral, a bizarre geometrical phenomenon that appears regularly in the natural world.

Surface Phase Diagrams for Wetting with Long-Ranged Forces

Physical Review Letters, 2023
Recent density functional theory and simulation studies of wetting and drying transitions in systems with long-ranged, dispersionlike forces, away from the near vicinity of the bulk critical temperature T_{c}, have questioned the generality of the global surface phase diagrams for wetting, due to Nakanishi and Fisher, pertinent to systems with short ...

FORC Diagrams in Magnetic Thin Films

2021
The first-order reversal curve (FORC) technique allows the use of bulk measurements to extract nanoscale features from hysteretic systems and separate intrinsic and interaction effects. Magnetic thin films in particular possess an extremely diverse and anisotropic energy landscape, which is complicated by interactions that exist on several length ...

Shearing Force and Bending Moment Diagrams

1972
Consider a cantilever AB, carrying a concentrated load W at the free end B, Figure 10.1(a). At any section C, the load W is tending to shear the beam (Figure 10.1(b)), this being resisted by the internal force exerted on CB by the adjacent part AC.

Accuracy of Harbeck Diagram for Forced Evaporation

Journal of the Energy Division, 1980
The Harbeck Diagram, a method for estimating the forced evaporation from a cooling pond, gives the fraction of heat load dissipated by evaporation as a function of windspeed and natural (unloaded) water surface temperature. The derivation of the diagram is presented, emphasizing the approximations that permit suppression of the temperature excess as an

Model FORC diagrams for hybrid magnetic elastomers

Journal of Magnetism and Magnetic Materials, 2017
Abstract We propose a model of hybrid magnetic elastomers filled with a mixture of magnetically soft and magnetically hard microparticles. The magnetically hard particles are described by the Stoner–Wohlfarth model, the magnetically soft phase obeys the Frohlich–Kennelly equation. The interaction between the two types of particles is described by the

Compositional Physics and Other Diagrams of Force

<p>At the beginning of every architectural act is an immaterial event. Volumetric fragments falling onto an open ground plane. Cubes casually stacked in a pile. A group of planks floating in zero gravity. Freestanding, unsteady walls falling in on one another. A thickened plane draped over geometric scraps.
