Recently our lab has shown that with broadband stimuli (either visual noise or natural scenes), performance for detecting oriented content is worst at horizontal, best at the obliques, and intermediate at vertical orientations--an anisotropy...

Multidimensional frequency estimation is a classic signal processing problem that has versatile applications in sensor array processing and wireless communications. Eigenvalue-based two-dimensional (2-D) and N -dimensional ( N -D) frequency...
High dynamic range imaging involves imaging at a bit depth higher than the typical 8-12 bits offered by standard video equipment. We propose a method of imaging a scene at high dynamic range, 14+ bits, to detect motion correlated with changes in...
Rapid Electrokinetic Patterning (REP) is a relatively new method for collecting and manipulating micrometer-scale particles at an electrode surface. REP is an AC electrokinetic technique that uses induced fluid motion to capture and manipulate...
Over the last 15 years, researchers have explored the use of piezoresistive microcantilevers/resonators as gas sensors because of their relative ease in fabrication, low production cost, and their ability to detect changes in mass or surface stress...
A Physics doctoral project seeks to reduce the uncertainty of inaccurate visual bridge inspections by producing a remote sensor program to determine and monitor the changes in health of a specified bridge. The Eastern Parkway Bridge was determined...
This study focuses on the variation in structural response to synthetic ground motions derived from the latest attenuation models developed for the Central Eastern United States (CEUS) and used by the USGS to develop the latest edition (2008) of...
Micro air vehicles (MAVs) are type of unmanned aircraft with a maximum length of 150 mm (6 in.) and flight speed of less than 10 m/s. Because their flight speed is comparable to the environmental wind speed coupled with their small size and low...
Polymorphisms in the adrenergic receptor beta-2 (ADRB2) gene have been studied in relation to risk of Type 2 diabetes and obesity, but few studies have investigated associations with breast cancer. The purpose of this research was to evaluate the...
Introduction: Children diagnosed with an Autism Spectrum Disorder (ASD) often lack the ability to recognize and properly respond to emotional stimuli. These emotional deficits are also observed in children with Attention-Deficit Hyperactivity...
A hyper basis function network (HyperBF) is a generalized radial basis function network (RBF) where the activation function is a radial function of a weighted distance. The local weighting of the distance accounts for the variation in local scaling...
Unrepaired DNA damage poses a serious threat to the genetic stability of a replicating cell. One mechanism of tolerating this damage is translesion DNA synthesis (TLS), in which an accessory polymerase synthesizes DNA directly across from a damaged...
Autism Spectrum Disorder (ASD) is an idiopathic pervasive neurodevelopmental disorder associated with various neuropathologies and immunological dysfunctions. Cytokines are regulatory proteins that facilitate communication between the immune and...
Science teachers--Certification; Science--Study and teaching (Elementary)
The purpose of this study was to discern what differences exist between the science inquiry learning environments created by National Board Certified Teachers (NBCTs) and non-NBCTs. Four research questions organized the data collection and...
