Modelling of a hysteresis motor using the Jiles-Atherton model [PDF]
, 2015 In this paper, we present a model of a hysteresis motor based on Maxwell's equations coupled with the Jiles-Atherton (J-A) hysteresis model solved by the finite element method.

Tip-Jump Response of an Amplitude-Modulated Atomic Force Microscope
Sensors, 2012 The dynamic behaviors of an Atomic Force Microscope are of interest, and variously unpredictable phenomena are experimentally measured. In practical measurements, researchers have proposed many methods for avoiding these uncertainties. However, causes of

Does Hysteresis in Unemployment Occur in OECD Countries? Evidence from Parametric and Non-Parametric Panel Unit Roots Tests [PDF]
This study tests the hysteresis hypothesis of unemployment in fourteen OECD countries by examining the stationarity of unemployment rates using several panel unit root tests.

Hysteresis and unemployment : a preliminary investigation [PDF]
, 2005 This paper points out what hysteresis is using a simple model of market entry and exit. A procedure for calculating hysteresis indices for economic time series is outlined.

Advanced Functional Materials, EarlyView.Significant nanoscale oxygen diffusion coefficient variations are measured in ferroelectric hafnium zirconium oxide films with grain boundaries and electrode interfaces exhibiting values 104 times larger than the grain cores. Overall coefficients are 10X larger for films prepared with metal nitride electrodes compared to refractory metals. New insights

Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies
Advanced Functional Materials, EarlyView.The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

Hysteresis in Unemployment [PDF]
The recent European experience of high persistent unemployment has led to the development of theories of unemployment hysteresis embodying the idea that the equilibrium unemployment rate depends on the history of the actual unemployment rate.

Parameter Identification of Latching Solenoid Including Permanent Magnets
Journal of Mechanical EngineeringThis article deals with the measurement and modelling of a latching solenoid containing permanent magnets. The aim of the research is to determine the flux linkage provided by the permanent magnets and the damping, which slows down the movement of the ...

Relationship between Concentration and Discharge on Storm Events: Case Study at Cakardipa Catchment, Cisukabirus Subwatershed, Upper Ciliwung Watershed, Bogor, West Java [PDF]
Journal of Tropical Soils, 2012 River nutrient loadings rates are frequently determined from discharge and hydrochemistry relationships usingregression techniques. Unfortunately such methods as a conventional technique are inadequate for dealing withthe problem such as differences in ...
