Direct torque control of permanent magnet synchronous motors with non-sinusoidal back-EMF
(2009-05-15)
This work presents the direct torque control (DTC) techniques, implemented in
four- and six-switch inverter, for brushless dc (BLDC) motors with non-sinusoidal back-
EMF using two and three-phase conduction modes. First ...
One dimensional electron spin imaging for single spin detection and manipulation using a gradient field
(2009-05-15)
The ability to resolve molecules individually has many potential applications.
These include understanding the local environments of single molecules including
details of their interactions with surroundings. The ability ...
Solution-mediated strategies for synthesizing metal oxides, borates and phosphides using nanocrystals as reactive precursors
(2009-05-15)
Because of their high surface area (and hence, increased reactivity) nanocrystals can be used as reactive precursors in the low-temperature synthesis of solid state materials. When nanocrystals are used as reactants, the ...
On countermeasures of worm attacks over the Internet
(2009-05-15)
Worm attacks have always been considered dangerous threats to the Internet since they can
infect a large number of computers and consequently cause large-scale service disruptions and
damage. Thus, research on modeling ...
Genetic analysis of equine 2', 5'-oligoadenylate synthetase (OASI) and ribonculclease L (RNASEL) polymorphims and association to severe West Nile Virus disease
(2009-05-15)
West Nile virus (WNV), a member of the Flaviviridae family of RNA viruses,
was first introduced to the United States in 1999 with rapid transmission across a variety
of hosts throughout the continental states. Genetic ...
Description of isoscalar giant dipole resonance in nuclei
(2009-05-15)
Applicability of the Hartree-Fock (HF) based random phase approximation (RPA) with
several Skyrme effective interactions to the description of the isoscalar giant monopole
(ISGMR) and the isoscalar giant dipole resonance ...
Making sense of divergent career test scores
(2009-05-15)
The purposes of this study were to discover patterns in test scores when both the Myers-Briggs Type Indicator and the Strong Interest Inventory are used simultaneously and to offer career counselors practical ways to ...
Automatic isochoric apparatus for PVT and phase equilibrium studies of natural gas mixtures
(2009-05-15)
We have developed a new automatic apparatus for the measurement of the phase equilibrium and pVT properties of natural gas mixtures in our laboratory. Based on the isochoric method, the apparatus can operate at temperature ...
Reading achievement of English language learners in 50/50 and 90/10 two-way dual language programs
(2009-05-15)
My study investigated the effects of two 50/50 and two 90/10 two-way dual
language programs on the reading achievement of 76 English Language Learners (ELLs)
from the end of third grade to the end of fourth grade. My study ...
Understanding mechanisms for C-H bond activation
(2009-05-15)
The results from density functional theory (DFT) studies into C–H bond
activation, hydrogen transfer, and alkyne–to–vinylidene isomerization are presented in
this work.
The reaction mechanism for the reductive elimination ...
