Sensorless Speed Control of Permanent Magnet-Assisted Synchronous Reluctance Motor (PMa-SynRM)
(2011-02-22)
An interesting alternative for today's high efficiency variable speed drives is the Permanent Magnet-Assisted Synchronous Reluctance Motor drive, which belongs to the family of brushless synchronous AC motor drives. ...
Characteristics of Effective Mentoring in a Formal Mentoring Setting
(2011-02-22)
A qualitative phenomenological study was conducted to determine the perceived
levels of effectiveness and barriers for a successful mentoring relationship between
mentors and mentees. Specifically, this study explored ...
Radar-Derived Forecasts of Cloud-to-Ground Lightning Over Houston, Texas
(2011-02-22)
Ten years (1997 - 2006) of summer (June, July, August) daytime (14 - 00 Z)
Weather Surveillance Radar - 1988 Doppler data for Houston, TX were examined to
determine the best radar-derived lightning forecasting predictors. ...
Population Dynamics of Plain Chachalacas in the Lower Rio Grande Valley
(2011-02-22)
The Lower Rio Grande Valley (LRGV) of Texas is an ecologically diverse region in the United States and marks the northernmost extension for many tropical species of plants and animals. Since the early 1900s, 95% of the ...
Nondestructive Testing of Overhead Transmission Lines: Numerical and Experimental Investigation
(2011-02-22)
Overhead transmission lines are periodically inspected using both on-ground and helicopter-aided visual inspection. Factors including sun glare, cloud cover, close proximity to power lines and the rapidly changing visual ...
Robust Optimization of Nanometer SRAM Designs
(2011-02-22)
Technology scaling has been the most obvious choice of designers and chip
manufacturing companies to improve the performance of analog and digital circuits.
With the ever shrinking technological node, process variations ...
Effect of Omega 3 Polyunsaturated Fatty Acids (PUFAs) on Markers of Inflammation in Young Horses in Training
(2011-02-22)
Sixteen horses (2 to 4 yr; 357 to 439 kg BW) were utilized in a randomized complete block design for a 140 d trial to determine effect of omega 3 PUFAs (n-3) supplementation on markers of inflammation in young horses in ...
Filter Design Considerations for High Performance Continuous-Time Low-Pass Sigma-Delta ADC
(2011-02-22)
Continuous-time filters are critical components in the implementation of large bandwidth, high frequency, and high resolution continuous-time (CT) sigma-delta (ΣΔ) analog-to-digital converters (ADCs). The loop filter defines ...
A Phenotypic Evaluation of 61 Mutated Lines of TAM 94L-25
(2011-02-22)
Among the available methods of creating selectable variation, induced mutagenesis has been historically under-utilized in cotton improvement. Dick Auld showed that chemical mutagenesis could be used to enhance fiber length ...
Numerical Simulation of the Flow Field in 3D Eccentric Annular and 2D Centered Labyrinth Seals for Comparison with Experimental LDA Data
(2011-02-22)
The flow field in an annular seal is simulated for synchronous circular whirl orbits with 60Hz whirl frequency and a clearance/radius ratio of 0.0154 using the Fluent Computational Fluid Dynamics (CFD) code. Fluent's Moving ...
