Saharan Dust and Pediatric Asthma : A Multinational, Multiyear Assessment in the Caribbean
(2020-09-09)Background: The annual seasonal intrusion of Saharan Dust to the Caribbean has been linked with asthma, a complex disease and a major cause of morbidity in the Caribbean and around the world. This first multinational, ... -
Sample Efficient Cost-Aware Active Learning
(2020-10-01)The grand vision of Artificial Intelligence is to build agents that can continuously learn from experience and reason about how to act in the world. Traditional machine learning models generally assume access to huge amount ... -
Sampling and Estimation on Large Online Social Networks
(2016-12)Studying the structural characteristics of online social networks (OSNs) provide useful information about the underlying OSN applications. Due to their very large sizes, sampling is a commonly used approach. One of the ... -
“SapSense”- Development of a Field Based Biosensor towards Wheat Pathogen Detection
(2017-12)Wheat is cultivated in almost all the states in the United States of America, and it is the third most cultivated crop in terms of acreage, producing a yield of 60 million tons per year. In 2016, world production of wheat ... -
Satellite Observations of Evolving Properties of Equatorial Ionospheric Plasma Structures
(2018-05)The Earth’s atmosphere contains a layer of plasma created primarily by photo-ionization of neutral species between 80 km and 1,000 km called the ionosphere. There are many complex processes near the equator where the Earth’s ... -
Saturation in Lock-Based Concurrent Data Structures
(2017-12)For over three decades, computer scientists enjoyed a "free lunch" inasmuch as they could depend on processor speeds doubling every three years. This all came to an end in the mid-2000's, when manufacturers ceased increasing ... -
Scalable and Secure Learning with Limited Supervision over Data Streams
(2018-07-17)Applications that employ machine learning over a stream of data provide the knowledge necessary for its users to make informed decisions at the right time. With the advantages of cloud computing infrastructure, these ... -
Scalable Learning Approaches for Sum-Product-Cutset Networks
(2016-12)Tractable models are a subclass of probabilistic graphical models (PGMs) in which exact inference can be performed tractably – a very desirable property missing from arbitrary PGMs like Bayesian and Markov networks – exact ... -
Scalable Low-Cost Large-Area Micro-Structured Thermal Neutron Detectors
(2020-12-03)Semiconductor thermal neutron (0.025 eV) detectors with micro-structured cavities backfilled with neutron conversion materials (10B, 6LiF) show a profound increase in the intrinsic thermal neutron detection efficiency as ... -
Scalable Synthesis and Dynamic Mechanical Characterization of Multifunctional Polymer Aerogels
(2020-05)Aerogels are low-density nanoporous solids containing hierarchical three-dimensional networks of nanoparticles pursued primarily for thermal and acoustic insulations and often for functionalization purposes. This work ... -
Scalable, Lifted Maximum a Posteriori Inference
(2016-12)This dissertation focuses on Markov logic networks (MLNs), a knowledge representation tool that elegantly unifies first-order logic (FOL) and probabilistic graphical models (PGMs). FOL enables compact representation while ... -
Scavenger Receptor A1 Distinguishes Bovine Serum Albumin-Coated Pristine and Carboxylated Multi-Walled Carbon Nanotubes
(2021-04-23)This dissertation concerns the interactions of multi-walled carbon nanotubes (MWNTs) with mammalian macrophages, cells that are first responders to foreign invaders in the body. The production and use of MWNTs are rapidly ... -
Scavenging of Particles by Cloud Droplets with Varying Particle Density and Relative Humidity
(2017-08)Results of a Monte Carlo trajectory model calculating collision rate coefficients between electrically charged 3.0μm radius cloud droplets and aerosol particles are presented in this work. For particles with radius less ... -
Scientific Fundamentals and Technological Development of Novel Biocompatible/Corrosion Resistant Ultrananocrystalline Diamond (UNCD) Coating Enabling Next Generation Superior Metal-Based Dental Implants
(2017-05)Current Ti-based dental implants exhibit failure (2-10%), due to various mechanisms, including chemical corrosion of the surface of the TiO2 naturally covered Ti-based implants. This thesis focused on developing a unique ... -
Secure Cloud Data Analytics with Trusted Processors
(2019-11-20)Over the last few years, data storage in cloud-based services has been very popular due to the easy management and monetary advantages of cloud computing. Recent developments showed that such data could be leaked due to ... -
Securing Autonomous Vehicles with Robust Physical Invariants
(2020-04-14)Automation is an exciting and developing field that, today, is growing at the speed of human innovation. Autonomous Vehicles (AVs) in particular are being implemented in pioneering ways across many industries—medical, ... -
Securing Binary Programs Without Perfect Disassembly
(2019-12)This dissertation introduces several approaches to improving the security, performance, and generality of binary software without source code. These source-free approaches have the advantage of being applicable to ... -
Securing Computations With GPUs
(2021-05-03)Many modern computers have two diverse computing models baked-in: CPUs and GPUs. The diversity of these computing models arises from their historically disparate purposes: Early CPU designs focused on rapidly executing ... -
Securing SGX Applications via Memory Safe Programming Languages and Augmented Runtime
(2019-12)Intel introduced Software Guard eXtensions (SGX) in its Skylake CPU, providing application programmers the ability to execute code in an isolated trusted execution environment (TEE) called an enclave. SGX isolates sensitive ... -
