Development of a Framework for Evaluating Yellow Timing at Signalized Intersections
(Virginia Center for Transportation Innovation and Research, 2011-02-01), FHWA/VCTIR 11-R12
Studies show that the proper design of clearance intervals has significant implications for intersection safety. For example, in 2001, approximately 218,000 red-light-running crashes occurred at signalized intersections ...
Field Performance of High Friction Surfaces
(Virginia Center for Transportation Innovation and Research, 2010-06-01), FHWA/VTRC 10-CR6
This report describes an evaluation of high friction surface (HFS) systems. The goal of this evaluation was to develop guidance for agencies when considering whether an HFS was an appropriate solution when addressing ...
Computer generation of binary Fresnel holography
(Optical Society of America, 2011-03-01)
Binarization of Fresnel holograms by direct thresholding based on the polarity of the fringe pattern is studied. It is found that if the hologram is binarized (i.e., for black and white hologram pixels) in this manner, ...

Controlled growth of epitaxial BiFeO3 films using self-assembled BiFeO3-CoFe2O4 multiferroic heterostructures as a template
(AIP Publishing, 2012-07-01)
The growth mechanism of a BiFeO3 layer deposited on self assembled (0.65) BiFeO3-(0.35) CoFe2O4 (BFO-CFO) composite thin films was studied. Epitaxial and self-assembled BFO-CFO thin films were deposited on SrTiO3 (111) ...
Alternating and direct current field effects on the structure-property relationships in Na0.5Bi0.5TiO3-x% BaTiO3 textured ceramics
(AIP Publishing, 2013-06-01)
The influence of alternating (ac) and direct current (dc) fields on the structural and dielectric properties of (PC) textured Na0.5Bi0.5TiO3-7%BaTiO3 (NBT-7%BT) ceramics has been investigated. X-ray diffraction ...
Method Of Multiple References For 3D Imaging with Fourier Transform Interferometry
(Optical Society of America, 2010-03-01)
This letter presents an improved phase referencing technique, called Method of Multiple References, for optical profilometry. Based on a lookup table, the method eliminates several major drawbacks of single-reference Fourier ...
Intensity image-embedded binary holograms
(Optical Society of America, 2013-01-01)
Past research has demonstrated that, by downsampling the source object scene in multiple directions, a binary Fresnel hologram can be generated to preserve favorable quality on the reconstructed image. In this paper, we ...
Incorporating Conductive Materials Into A Photonic Crystal Fiber: Toward Optoelectronic Applications
(Optical Society of America, 2012-04-01)
We report a method to selectively fill arbitrary air holes of microstructured photonic crystal fibers with conductive materials through microsphere-assisted fabrication. A photonic crystal fiber with three of its air holes ...
The influence of interface bonding on thermal transport through solid-liquid interfaces
(AIP Publishing, 2013-06-01)
We use time-domain thermoreflectance to show that interface thermal conductance, G, is proportional to the thermodynamic work of adhesion between gold and water, W-SL, for a series of five alkane-thiol monolayers at the ...
