Energy Dissipation during Geomagnetic Storms
(2021-12-20)
Some fraction of the solar wind energy is transferred to the Earth magnetosphere
and ionosphere. Sometimes this transfer of energy is exceptionally large,
producing a magnetic storm. Storms occur when the Interplanetary ...
THE ARECIBO OBSERVATORY AS AN INSTRUMENT FOR INVESTIGATING ORBITAL DEBRIS
(2021-11-22)
In this dissertation, the Arecibo Observatory, both past and future, as an instrument for investigating orbital debris is investigated. For over three decades, models of the orbital debris environment in low Earth orbit ...
Orbital Evolution Studies and Radio Searches of Extra-Solar Moons
(2021-12-13)
Exoplanetary research has undergone a great deal of development and growth. Achievements in theoretical studies and detection techniques have led to the discovery of 4,000+ exoplanets in ~3, 000 planetary systems to date. ...
THE COMMISSIONING OF THE LOW FREQUENCY ALL SKY MONITOR, THE FIRST DISTRIBUTED PHASED ARRAY TELESCOPE SPECIFICALLY DESIGNED TO SEARCH FOR RADIO TRANSIENTS AT LONG WAVELENGTHS
(2021-05-15)
The last two decades have seen a proliferation in the development of technology for low frequency radio astronomy based upon phased elements grouped into one or more large stations. Instruments fielding multiple large ...
ns2-md0 Post-Transition Metal Oxides for Solar Energy Applications
(2020-08-10)
Meeting the growing global energy demand while mitigating the deterioration of the global climate requires the rapid introduction of clean, renewable, and sustainable fuels. Solar energy output at daytime provides more ...
INVESTIGATION OF NANOSTRUCTURES FOR HIGHLY SENSITIVE SURFACE PLASMON RESONANCE SENSORS
(2020-08-11)
An extensive study of Surface Plasmon Polaritons (SPPs) and their applications has been undertaken in this work. Highly sensitive surface plasmon resonance sensors, made of noble metals, as well as multilayer nanostructures, ...
Toward Background-Free Methods to Search For Majorana Neutrinos in Xenon Gas
(2020-08-11)
Since the observation of double beta decay 33 years ago the search for neu- trinoless double beta decay has been underway. This is due to the fact that a robust observation of neutrinoless double beta decay is currently ...
Multiscale ionospheric electrodynamics and their impacts on the ionosphere-thermosphere system
(2020-08-11)
In this dissertation, multiscale ionospheric electrodynamics at different latitudinal regions and their impacts on the ionosphere and thermosphere (I-T) system have been studied in three aspects. Firstly, impacts of the ...
Observation and analysis of unexplored low-energy electron emission processes revealed using a low-energy positron beam
(2020-08-17)
This dissertation presents measurements of the kinetic energy distributions of low-energy, positron-induced electrons emitted from single-layer of graphene (SLG), highly oriented pyrolytic graphite (HOPG), Si, Cu and TiO2 ...
Searching for a Pair-Produced Supersymmetric Top Partner Using Recursive Jigsaw Variables and Boosted Decision Trees with 139 fb⁻¹ of Data From the ATLAS Detector
(2020-07-21)
The Standard Model of Particle Physics is the most comprehensive theory describing how fundamental particles and three of the four fundamental forces are related. However, the Standard Model is known to be an incomplete ...
