Three dimensional magnetic field computation by a coupled vector-scalar potential method in brushless DC motors with skewed permanent magnet mounts - the no-load and load results
(
IEEE
, 1994 , Article)
The coupled magnetic vector potential-magnetic scalar potential (CMVP-MSP) method of computation of 3D magnetic fields by finite elements (3D-FE), whose theoretical development and formulation were detailed in a companion ...
Determination of amitriptyline, imipramine and orphenadrine in antidepressant drugs by potentiometry, spectrophotometry and atomic absorption spectrometry
(
Springer-Verlag
, 1993 , Article)
Methods are described for the determination of amitriptyline, imipramine and orphenadrine in some antidepressant drugs. They are based on a prior reaction with ammonium reineckate to form 1∶1 water-insoluble drugreineckate ...
Radon concentration determination in some dwellings of Doha city of Qatar
(
Elsevier
, 1997 , Article)
Yearly average radon concentrations have not been reported yet in Qatar. Only few measurements on indoor radon concentrations have been conducted during the autumn season in 1992. To complete these measurements a determination ...
A coupled vector-scalar potential method for permanent magnet modeling in large-scale 3D-FE magnetic field computations
(
IEEE
, 1993 , Article)
This paper introduces a magnetic scalar potential (MSP) formulation to model permanent magnet volumes. This formulation is suited for use in coupled vector-scalar magnetic potential (CMVP-MSP) 3D-FE computations of large-scale ...
Mercurimetric potentiometric determination of barbiturates using a solid-state iodide ion-selective electrode
(
Taylor and Francis Inc.
, 1997 , Article)
A simple potentiometric method is described for mercurimetric titration of barbiturates using a solid-state iodide ion-selective electrode. The optimum titration conditions involve the use of a borate buffer of pH 9-10 as ...
An Adaptive Newton-Raphson Technique for Combined Vector-Scalar Potential Solutions of Large Scale 3D Magnetic Field Problems Involving Anisotropic Materials
(
IEEE
, 1993 , Article)
In general, magnetic field problems in electrical devices and machines are of nonlinear nature due to magnetic saturation in their ferrous cores. In the combined magnetic vector-magnetic scalar potential (MVP-MSP) method ...
Thiamine-reineckate liquid membrane electrode for the selective determination of thiamine (vitamin B1) in pharmaceutical preparations
(
The Royal Society of Chemistry
, 1989 , Article)
The construction and electrochemical response characteristics of a liquid membrane electrode for thiamine (vitamin B1) based on the formation of an ion pair between the thiamine cation and the reineckate anion in nitrobenzene ...
Positron annihilation lifetime study of pure and treated polyvinyl chloride
(
scientific.net
, 1997 , Article)
Positron annihilation lifetime technique (PAL) has been applied to investigate the behavior of the free volume in pure and doped polyvinyl chloride (PVC) as a function of Pb concentration and temperature. It is noticed ...
Teaching Electric Machinery and Associated Electromagnetic Fields-A Case for the Benefits of Academic Computing
(
IEEE
, 1993 , Article)
This paper describes three broad categories of benefits resulting from use of and access to personal computers (PCs) and work stations (WSs) in teaching electric machines and drives. This includes all the electromagnetic ...
