A solution method determining the effect of spin upon gravitational effects in the surroundings of a black hole
(East Carolina University, 2017-12-12)
Using the theory of General Relativity and quasi-normal modes (QNMs) from the Teukolsky equation as a source of quasi-periodic oscillations (QPOs) from black holes provides information about black hole mass and spin. This ...
Optimizing graphene oxide reduction via laser irradiation
(East Carolina University, 2017-01-04)
The present report discusses a single step method to reduce graphene oxide via laser irradiation. A computer numerically controlled laser engraver equipped with a 450nm laser diode was engineered to conduct this research. ...
Fast Carbon-Ion and Proton Induced Electron Emission from Condensed-Phase Biological Targets
(East Carolina University, 2018-07-23)
Fast charged particles interact with matter through various ionization and excitation pathways that aren't fully understood. Predicting the effects of these interactions is vital in many fields such as radiation therapy, ...
Flow cytometer apparatus for three dimensional difraction imaging and related methods
(2015-04-21)
A flow cytometer assembly includes a fluid controller configured to form a hydrodynamically focused flow stream including an outer sheath fluid and an inner core fluid. A coherent light source is configured to illuminate ...
Multi-wavelength beam splitting systems for simultaneous imaging of a distant object in two or more spectral channels using a single camera
(2016-09-29)
An optical imaging system and related methods are provided that acquire images of an object at a distance in different spectral regions using only one camera. The systems and methods are adaptable to applications where ...
Methods and systems for optically characterizing a turbid material using a structured incident beam
(2010-04-08)
Methods and systems for optically characterizing a turbid sample are provided. A structured light beam is impinged on the sample. The sample includes an embedded region. A reflected light image of the structured light beam ...
Optical Pulling, Optical Deflection, and Optical Trapping of Single Airborne Particles using Negative Photophoresis
(East Carolina University, 2016-05-03)
Optical manipulation is the use of light to control the motion of objects. This thesis focuses on the development of optical transportation technology via optical pulling with application to the characterization of single ...
Graviton and photon orbitals surrounding a black hole : Application to the supermassive black hole at the Milky Way galactic center, with NIR observational confirmation.
(East Carolina University, 2014)
Non-relativistic Quantum Theory fairly accurately describes the resonance phenomena around a black hole, even though black holes are thought of as general relativistic (GR) objects. Graphically and numerically we are able ...
Realistic optical cell modeling and diffraction imaging simulation for study of optical and morphological parameters of nucleus
(2016-01)
Coherent light scattering presents complex spatial patterns that depend on morphological and molecular features of biological cells. We present a numerical approach to establish realistic optical cell models for generating ...
Study of Morphology Based Cell Assay by Diffraction Imaging Flow Cytometry
(East Carolina University, 2015)
Development of an accurate and label-free method for single cell assay attracts intensive research efforts for its importance to cell biology research and clinicG14G7al applications. Flow cytometry is one of the most widely ...
