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 ...
First-order quantum phase transition in adiabatic quantum computation
(American Physical Society, 2009-12-01)
We investigate the connection between local minima in the problem Hamiltonian and first-order quantum phase transitions during adiabatic quantum computation. We demonstrate how some properties of the local minima can lead ...
Spiral CT of the Temporal Bone
(2010-11-01)
Maximum image resolution with commercial spiral CT scanners is inadequate to define clearly the anatomical features and electrode positions within this intricate, 3D space. The objective of this research was to develop ...
Fast CT Reconstruction - Practical Performance via Parallelization
(2008-06-12)
Parallel computing has been used to solve large-scale problems in many fields. While CT is being developed towards high-resolution, volumetric, dynamic and spectral imaging, datasets become increasingly large, and ...
How to Define the Next Generation Cardiac CT Architecture? - a Contemporary Challenge for Interdisciplinary Collaboration
(2010-05-21)
Cardiovascular diseases are pervasive with high mortality and morbidity at tremendous social and healthcare costs. There are urgent needs for significantly higher fidelity cardiac CT with substantially lower radiation dose, ...
Phase stitching and error correction in aperture synthesis for generalized phase-shifting interferometry
(Optical Society of America, 2013-07-01)
An accurate aperture synthesis method in generalized phase-shifting interferometry is suggested to improve the quality of the reconstructed object wavefront by stitching both the phase and the real amplitude of the object ...
Network-Based Prediction and Analysis of HIV Dependency Factors
(Public Library of Science, 2011-09-22)
HIV Dependency Factors (HDFs) are a class of human proteins that are essential for HIV replication, but are not lethal to the host cell when silenced. Three previous genome-wide RNAi experiments identified HDF sets with ...
Deviation Influences on Sectional Image Reconstruction in Optical Scanning Holography Using A Random-Phase Pupil
(Optical Society of America, 2013-10-01)
In this paper, we analyze the influence of two kinds of deviation errors on sectional image reconstruction for an optical scanning holography system using a random-phase pupil. The first deviation occurs in the lateral ...
Novel method for converting digital Fresnel hologram to phase-only hologram based on bidirectional error diffusion
(Optical Society of America, 2013-10-01)
We report a novel and fast method for converting a digital, complex Fresnel hologram into a phase-only hologram. Briefly, the pixels in the complex hologram are scanned sequentially in a row by row manner. The odd and even ...
Integrated Airline Schedule Design and Fleet Assignment: Polyhedral Analysis and Benders' Decomposition Approach
(INFORMS, 2010)
The main airline operations consist of schedule planning, fleet assignment, aircraft routing, and crew scheduling. To improve profitability, we present in this paper an integrated fleet assignment model with schedule ...
