Improved rotor position estimation in extended back-EMF based sensorless PM brushless AC drives with magnetic saliency [PDF]
, 2007 An improved extended back-EMF based sensorless control method is proposed for a brushless AC motor equipped with an interior permanent magnet rotor. It accounts for dq-axis cross-coupling magnetic saturation by introducing an apparent mutual winding ...

Adhesive Contact to a Coated Elastic Substrate [PDF]
, 2007 We show how the quasi-analytic method developed to solve linear elastic contacts to coated substrates (Perriot A. and Barthel E. {\em J. Mat. Res.}, {\bf 2004}, {\em 19}, 600) may be extended to adhesive contacts. Substrate inhomogeneity lifts accidental

An extended finite element method with smooth nodal stress [PDF]
, 2013 The enrichment formulation of double-interpolation finite element method (DFEM) is developed in this paper. DFEM is first proposed by Zheng \emph{et al} (2011) and it requires two stages of interpolation to construct the trial function.

A narrow-band unfitted finite element method for elliptic PDEs posed on surfaces [PDF]
, 2015 The paper studies a method for solving elliptic partial differential equations posed on hypersurfaces in $\mathbb{R}^N$, $N=2,3$. The method allows a surface to be given implicitly as a zero level of a level set function.

Numerical simulation of the magnetization of high-temperature superconductors: 3D finite element method using a single time-step iteration [PDF]
, 2008 We make progress towards a 3D finite-element model for the magnetization of a high temperature superconductor (HTS): We suggest a method that takes into account demagnetisation effects and flux creep, while it neglects the effects associated with ...
