Free-Electron Lasers like the one at the SLAC National Accelerator Laboratory are sources of extremely bright X-rays that are useful in a variety of scientific imaging applications. Because there are only a handful of FEL facilities around the world, access to these X-rays is in…

Passive micromixers focus on variations in the channel geometry and the presence of flow obstacles as a means of improving mixing efficiency. An analysis of these geometries can provide useful information for further mixer design iteration. These passive micromixers have applica…
In this work, to address the sampling problem for systems at high densities and low temperatures, a generalized identity exchange algorithm is developed for grand canonical Monte Carlo simulations. The algorithm, referred to as Molecular Exchange Monte Carlo (MEMC), is implement…
Siber-Fiziksel Sistemler’den elde edilen Çok-değişkenli Zaman Serileri (CZS) verisi, sistemin karakteristik özellikleri hakkında değerli bilgiler içermektedir. Bir Makine Öğrenmesi yöntemi olan, Çok-değişkenli Zaman Serileri (CZS) Kümelemesi, sistemin değişik çalışma aralıkların…
The study of open physical systems concerns finding ways to incorporate the lack of information about the environment into a theory that best describes the behavior of the system. We consider characterizing the environment by using the system as a sensor, mitigating errors, and …
Computational Fluid Dynamics (CFD) is a useful tool when it comes to research in the fields of Aerodynamics, Turbomachinery, and is used in several other fields of research. CFD is an important tool in the engineering industry because it allows for understanding and evaluation o…
Dissolved oxygen is an important parameter of water quality in aquaculture. Aeration has been known to improve oxygen levels and yields, but its use is uncommon in many developing world environments due to high costs. As a more effective implementation, this thesis presents the …
Recent experimental and computational investigations have provided a comprehensive phenomenological description of unsteadiness in nominally two-dimensional (2-D), spanwise homogeneous shock-wave/turbulent-boundary-layer interactions (STBLIs), including both the impinging-shock …
In the recent years, atomistic calculations have had a significant impact on materials science with a strong emphasis toward materials design. These calculations provide the basis for systematic screening and detailed analysis of materials properties which is critical to sustain…
If a single phrase can be said to embody modern perspectives on many-body theory, it is P.W. Anderson's famously simple line, "More is different". This idea is well understood by practitioners of many-body theory, and field theory more generally, as drawing a distinction between…
Most technological relevant structural materials are polycrystals that contain many (millions) so-called grains. Plastic deformation in polycrystalline metallic materials is not homogeneous at the microscale, but sometimes strongly heterogeneous among grains and varies spatially…
In collisionless and weakly collisional plasmas, the particle distribution function is a rich tapestry of the underlying physics. However, actually leveraging the particle distribution function to understand the dynamics of a weakly collisional plasma is challenging. The equatio…
The CycleGAN generative adversarial network is applied to simulated electro-optical (EO) images in order to transition them into a Synthetic Aperture Radar (SAR)-like domain. If possible this would allow the user to simulate radar images without computing the phase history of th…
Fractional calculus introduces tractable mathematical tools for accurate description of anomalous phenomena, regarded as a manifestation of self-similar structures and memory effects. Fractional approaches in modeling anomalous dynamics have been increasingly employed over the l…
Reservoir characterization and history matching are essential steps in various subsurface applications, such as petroleum exploration and production and geological carbon sequestration, aiming to estimate the rock and fluid properties of the subsurface from geophysical measureme…
Future space telescopes will provide us with the opportunity to characterize the atmospheres of terrestrial planets orbiting within the habitable zones of their stars. In the near future, the James Webb Space Telescope (JWST) will allow us to spectrally characterize terrestrial …
Manufacturing processes are known for their intricacies in changing material shapes and properties. New generations of manufacturing technologies, known as flexible manufacturing, are moving toward design freedom, which allows producing parts with optimized geometries and high c…
The lifespan of a galaxy is punctuated by both mergers and flybys, yet most methods to track the galaxy assembly history within a cosmological simulation are designed to identify only mergers. Here, we present the full halo interaction network for several runs of the Illustris s…
Advanced Polymer and Ceramic Matrix Composites (PMCs and CMCs) are currently employed in a variety of airframe and engine applications. This includes PMC jet engine fan cases and CMC hot gas path turbine components. In an impact event, such as a jet engine fan blade-out, PMCs ex…
