Quantification of information flow in cyber physical systems
<p>"In Cyber Physical Systems (CPSs), traditional security mechanisms such as cryptography and access control are not enough to ensure the security of the system since complex interactions between the cyber portion and physical portion happen frequently. In particular, the physical infrastructure …

Influence of hydrodynamics on the larval supply to hydrothermal vents on the East Pacific Rise
… and temporally, and correlation with concurrent physical observations can provide insights into larval transport mechanisms that contribute to structuring marine benthic communities. In order to facilitate field studies, this thesis first provides new morphological and genetic identifications for …

Scalable Surrogates for Counts and Computer Experiments
… space scientists to revise hypotheses about the physical processes, and computer simulations under those models, that are in play at the boundary of our solar system. Providing estimates and associated uncertainty quantification (UQ) of the rate at which ENAs are generated is vital to theory …

Thermal Modeling of Cooling Time of Submarine Dacite Lapilli Tuff: Brothers Volcano, Kermadec Arc
… of 100°C in eruption temperature.</p> <p>While physical observations of whole rock samples indicate brecciation, earlier paleomagnetic work proves coherent primary magnetization with the same inclination of the Geocentric Axial Dipole, suggesting deposition during a single eruption. The combined …

Analyzing and Modeling the Effects of Independent Variables on Texas Severe Work Zone Crashes
… analysis. Using statistical analysis and physical observations, this document will be modeling the different factors to determine their contribution to severe crash risk in work zones. For this research, crash severity will be selected as the dependent variable. Though all crashes are …

Imagined Futures: The impact of mlearning and access to mobile technology on the role of the teacher
… using interviews, video analysis, online observations and physical observations of classes. Some methods were extensions or innovations on traditional grounded theory approaches. These data were analysed through the process of constant comparison, from which codes and categories emerged. …

Seaglider observations of biogeochemical variability in the Iberian upwelling system.
… studying the region using traditional shipboard observations. This thesis demonstrates an alternative sampling technique, providing high spatial and temporal resolution biogeochemical data through the use of an autonomous underwater gliderthe Seaglider. SG510 “Orca” was outfitted with sensors to …

Reducing emissions of a large bore two stroke cycle engine using a natural gas and hydrogen mixture
… gas. Engine and emissions data were recorded and physical observations were also noted, such as engine misfires. Results showed that the addition of hydrogen into the fuel gas without the use of a pre-combustion chamber reduced emissions. The addition of the pre-combustion chamber reduced …

Exponential Smoothing for Forecasting and Bayesian Validation of Computer Models
… used to investigate complex systems for which physical experiments are highly expensive or very time-consuming. Before using a computer model, we need to address an important question ``How well does the computer model represent the real system?" The process of addressing this question is …

Shear fatigue of adhesively bonded frictional interfaces in high-strength steel
This thesis presents new experimental data, physical observations and a new analytical model relevant for the design of bonded/bolted hybrid joints in high-strength steel plates subjected to cyclic shear loading. Hybrid joints can have improved fatigue endurance as compared to welded connections of …

Behavior of Deep Reinforced Concrete Beams under Monotonic and Reversed Cyclic Load
… showed that the new model is consistent with physical observations and explains the transition from deep to slender beams. Furthermore, it was shown that the ISTM can be used in combination with the above-mentioned kinematic model for estimation of the ultimate displacement and deformed shape …

Physical processes and zooplankton distribution in the Great South Channel : observational and numerical studies
… of a tightly integrated set of biological and physical observations made in the GSC by means of a new instrument, the Video Plankton Recorder (VPR); and a two-dimensional Eulerian numerical model that simulates one way in which a physical flow field, combined with a biological behavior pattern, …

Seismic Behavior of Simcon-Jacketed High Strength Lightweight Aggregate Fiber Reinforced Concrete Filled Steel Tube Column Members
Earthquake resistant structures and structures deteriorated due to earthquake and lack of durability inspired engineers to develop novel structural systems. During the recent decades advanced fiber reinforced cementitious composites such as High-Performance Fiber Reinforced Concretes (HPFRCs) have …
