Modeling of Permanent Magnets in 3-d Space Using Edge Nite Elements Typeset Using Revt E X 1

چکیده
A surface integration method for modeling of permanent magnets in 3-D space using edge nite elements is presented, where the value of the coercive magnetic forceH c is integrated only over the entire surface area of the permanent magnet. This allows direct computation of the equivalent source current values, which are afterwards assigned to the surface edges of the permanent magnet. The main advantages of the proposed method are: accurate results with less computational e ort and improved convergence rate of the iterative solver. Veri cation of this surface integration method is carried by comparing the results with those obtained by the Biot-Savart Law and the traditional current-sheet method. Finally, a comparison between the numerical results obtained through the surface integration method and the measured results of a complex electromagnetic device with permanent magnets is given.

Why Odd-space and Odd-time Dimensions in Even-dimensional Spaces? * Typeset Using Revt E X * Nbi-he-00-26
We are answering the question why 4-dimensional space has the metric 1+ 3 by making a general argument from a certain type of equations of motion linear in momentum for any spin (except spin zero) in any even dimension d. All known free equations for non-zero spin for massless fields belong to this type of equations. Requiring Hermiticity1 of the equations of motion operator as well as irreduci...

The elds generated by \quarks" in the adjoint representation of SU(2) color are analyzed in the scaling region of the four-dimensional lattice theory. Evidence of vacuum screening of adjoint quarks is obtained from a comparison of quark-antiquark (QQ) ux-tubes for quarks in the adjoint (\isospin" j = 1) and fundamental (j = 1=2) representations. The component E j of the colorelectric eld streng...

متن کاملContinuum Study of Deconnnement at Nite Temperature Typeset Using Revt E X
Deconnnement and chiral symmetry restoration are explored in a connning, renormalisable, Dyson-Schwinger equation model of two-avour QCD. An order parameter for deconnnement is introduced and used to establish that, in the chiral limit, deconnnement and chiral symmetry restoration are coinci-dent at T c 150 MeV. The transitions are second order and each has the same critical exponent: 0:3. The ...
