Numerical investigation of mesh size convergence rate of the finite element method in MESFET simulation
(Elsevier, 1981-06)
The mesh size convergence rate of the finite element method in two-dimensional GaAs MESFET simulation has been investigated numerically. The equations governing MESFET operation and the finite element formulation of these ...
Structure and morphology of magnetron sputtered CoCr thin films
(Elsevier, 1991-12-02)
The growth characteristics of magnetron sputtered Co-22%Cr thin films on amorphous glass or carbon substrates have been investigated utilizing transmission electron microscopy, X-ray diffraction and electrical resistivity ...
Mapping of spectral density functions using heteronuclear NMR relaxation measurements
(Elsevier, 1992-06-15)
A method is proposed for direct mapping of spectral density functions of the rotational motions of H-X bond vectors, such as 1H---15N, by measuring a set of NMR relaxation parameters. The well known and frequently measured ...
Peritumoral tissue compression is predictive of exudate flux in a rat model of cerebral tumor: an MRI study in an embedded tumor
(Wiley Periodicals, Inc.Springer, 2015-11)
Transient Responses of a Heterogeneous Spin System to Binomial Pulse Saturation
(Elsevier, 1993-03)
The transient responses of a heterogeneous spin system to binomial pulses applied at the free-water resonance frequency are obtained by solving the Bloch equations pertaining to such a system modeled by a pair of binary ...
Geometrical optimization of longitudinally pumped solid-state lasers
(Elsevier, 1991-12-01)
We use a simplified analysis of gain saturation in longitudinally pumped lasers or amplifiers to study the effect of the relative pump and laser beam size. We derive a simple rule of thumb allowing one to optimize the efficiency.
Solid state- and magneto-chemistry of the SrO-Fe2O3 system : III. The non-existence of single-phase "SrFe2O4"
(Elsevier, 1979-11)
A detailed Mossbauer investigation of 1 : 1 SrO : Fe2O3 has shown that a single phase with the SrFe2O4 composition does not exist in the SrO-Fe2O3 system when SrCo3 and Fe2O3 are reacted in air. A multiphase assemblage of ...
A new technique of incoherent complex signal detection
(Elsevier, 1978-10)
A new technique of incoherent complex spatial filtering is presented. The advantage of this technique is its use of white light, for which the unavoidable coherent noise in the coherent optical processor may be removed. ...
