Title: A SINGLE-PIXEL HYPERSPECTRAL IMAGING SYSTEM FOR CANCER MARGIN DETECTION
Author: Peller, Joseph
Date Created: 2018
Subjects--Topical: Optics, Physics
Description: We have developed a hyperspectral imaging (HSI) system based on a single pixel camera design to detect differences in tissue properties based on the optical reflectance and autofluorescence spectra of the tissue. The long-term goal of this project...

Title: ACCURATE AND EFFICIENT CALCULATION OF SINGULAR ELECTROSTATIC POTENTIALS IN CHARGE-DIELECTRIC SPHERICAL AND JANUS PARTICLE SYSTEMS
Author: Retz, Caylah
Date Created: 2018
Subjects--Topical: Molecular biology, Mathematics, Physics
Description: We introduce an efficient and accurate boundary element method for computing the electrostatic potential in closely-packed dielectric spheres and Janus particles. Close physical proximity occurs in modeling molecular ion interactions or colloidal ...

Title: CHARACTERIZATION OF LIGHT-META STRUCTURE INTERACTIONS
Author: Chandra, Nitish
Date Created: 2018
Subjects--Topical: Optics, Physics
Description: The advent of metamaterials has increased the complexity of possible light-matter interactions, creating gaps in knowledge and violating various commonly used approximations and rendering some common mathematical frameworks incomplete. Our forward...

Title: IN-SITU MEASUREMENT OF DIMENSIONS AND SURFACE PROFILE OF AXISYMMETRIC OBJECTS USING FRINGE PROJECTION TECHNIQUE
Author: Farahi, Navid
Date Created: 2018
Subjects--Topical: Optics, Physics
Description: Fringe projection technique has been a powerful tool for 3D metrology and surface profilometry with high repeatability. However, for in-situ measurement of objects with highly specular surfaces, large dimensions, and large varying slopes, acquirin...

Title: Metasurfaces for Field Control and Detection
Author: Rosenbury, Christopher
Date Created: 2018
Subjects--Topical: Optics, Nanoscience, Physics
Description: Metasurfaces have been of increasing interest in the scientific community due to their consistent ability to efficiently reproduce traditional optical elements via quasi-monolithic patterning. In this dissertation I will examine various metasurfac...

Title: Molecular clustering characteristics in ternary trehalose and choline dihydrogen phosphate solutions
Author: Nikulsin, Nikita
Date Created: 2018
Subjects--Topical: Physics
Description: Spatial and temporal characteristics of molecular structure in ternary solutions of trehalose and choline dihydrogen phosphate (CDHP) are studied using molecular dynamics simulations at 300 K for a range of solute concentrations with a 2:1 stoichi...

Title: New Algorithms for Protein Structure Analysis: From Nonparametric Density Estimation to Characterization of Molecular Volume Spatial Distributions
Author: Farmer, Jenny
Date Created: 2018
Subjects--Topical: Bioinformatics, Biophysics, Physics
Description: The Flexibility and Stability Test (FAST) is a C++ class library designed in the early 2000’s to execute free energy decomposition and reconstitution operations applied to protein structures. The library has been substantially expanded to include ...

Title: Propagation properties of Hermite non-uniformly correlated beams in turbulence
Author: Gbur, Greg, Yu, Jiayi
Date Created: 2018
Subjects--Topical: Physics, Optics
Description: We study the propagation properties (intensity, degree of coherence and scintillation) of a new class of beams in a turbulent atmosphere, which are called Hermite non-uniformly correlated (HNUC) beams. The results show that the beams not only have...

Title: Rectangular Hermite non-uniformly correlated beams and its propagation properties
Author: Gbur, Greg, Yu, Jiayi, Cai, Yangjian
Date Created: 2018
Subjects--Topical: Physics, Optics
Description: We introduce a new class of non-uniformly correlated beams that are called rectangular Hermite non-uniformly correlated (RHNUC) beams, which possess rectangular symmetry in their degree of coherence. It is shown that, in free space and in turbulen...
