Signal Processing Of White-Light Interferometric Low-Finesse Fiber-Optic Fabry-Perot Sensors
(Optical Society of America, 2013-08-01)
Signal processing for low-finesse fiber-optic Fabry-Perot sensors based on white-light interferometry is investigated. The problem is demonstrated as analogous to the parameter estimation of a noisy, real, discrete harmonic ...
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 ...
GPU Power Prediction via Ensemble Machine Learning for DVFS Space Exploration
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2018-02-02), TR-18-01
A software-based approach to achieve high performance within a power budget often involves dynamic voltage and frequency scaling (DVFS). Consequently, accurately predicting the power consumption of an application at different ...
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 ...
CommAnalyzer: Automated Estimation of Communication Cost on HPC Clusters Using Sequential Code
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2017-08-14), TR-17-04
MPI+X is the de facto standard for programming applications on HPC clusters. The performance and scalability on such systems is limited by the communication cost on different number of processes and compute nodes. Therefore, ...
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 ...
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 ...
The Ph-t/Ph-t/infinity queueing system: Part I - the single node
(INFORMS, 2004)
We develop a numerically exact method for evaluating the time-dependent mean, variance, and higher-order moments of the number of entities in a Ph-t/Ph-t/infinity queueing system. We also develop a numerically exact method ...
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 ...
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 ...
