Signatures of the El Nino-southern oscillation on rainfall and cave dripwater oxygen isotopes in N. Borneo
(Georgia Institute of Technology, 2019-12-11)
Oxygen isotope (δ18O) records of speleothem carbonates are a critical terrestrial paleoclimate archive, providing insight into past hydroclimate variations and past changes in atmospheric circulation. Specifically, time ...
Numerical study of the dynamic processes in volcanic eruptions: Bubble dynamics and volatiles diffusion
(Georgia Institute of Technology, 2017-04-06)
Volcanic eruption releases gases and aerosols (e.g., sulfur compounds) to the atmosphere, impacting climate for up to several years. While most research efforts of volcanologists to date have been devoted to unraveling the ...
Geophysical and remote sensing study of terrestrial planets
(Georgia Institute of Technology, 2016-07-12)
The overarching theme of this dissertation is the study of the evolution of terrestrial planets and its effect on surface processes and planetary habitability. In many regards, planetary habitability is an enthralling yet ...
Softair: Software-defined networking and network function virtualization solutions for 5g cellular systems
(Georgia Institute of Technology, 2017-05)
One of the main building blocks and major challenges for 5G cellular systems is the design of flexible network architectures, which can be realized by the paradigm of software-defined networking (SDN) and network function ...
Measurements of emissions from agricultural fires and wildfires in the U.S.
(Georgia Institute of Technology, 2016-11-09)
Biomass burning (BB) produces significant amounts of trace gases and aerosol, which play important roles in atmospheric chemistry and climate. This study presents detailed airborne measurements of emissions from 15 ...
Systematic study of earthquake triggering using microearthquakes detected by the matched filter technique
(Georgia Institute of Technology, 2015-06-18)
Earthquakes can be promoted or inhibited by surprisingly small stress perturbations, known as earthquake triggering. The stress perturbations can stem from various natural and anthropogenic processes. The most common stress ...
Measurement of pernitric acid and inorganic bromine species using chemical ionization mass spectrometry
(Georgia Institute of Technology, 2016-09-21)
Measurements of atmospheric trace gases is a central aspect of the study of atmospheric chemistry. It allows scientists to explore the atmosphere. Chemical ionization mass spectrometry (CIMS) has been utilized to measure ...
A concise survey of the occurrence and varying formation environments of feldspathic rocks in the southern highlands, Mars
(Georgia Institute of Technology, 2016-12-09)
Presented here, is a synthesis of previous studies that have resulted in the discovery of feldspathic material on the Martian surface through the utilization of orbital (e.g., OMEGA on Mars Express and CRISM on MRO) and ...
Reactive transport in natural porous media: contaminant sorption and pore-scale heterogeneity
(Georgia Institute of Technology, 2012-08-22)
Reactive Transport Models (RTMs) provide quantitative tools to analyze the interaction between transport and biogeochemical processes in subsurface environments such as aquatic sediments and groundwater flow. A tremendous ...
A multiscale analysis of heat transfer in porous media
(Georgia Institute of Technology, 2017-11-02)
The modeling of thermal convection in porous media is a challenging task due to the inherent structural and thermophysical heterogeneities that permeate over several scales. In the present thesis, I address several issues ...
