Modelling V-Band Atmospheric Loss With Deep Learning, Ralph Lyndon Gesner

Electrical and Computer Engineering ETDs

Modelling atmospheric loss is fundamental to implementation of future mm-wave terrestrial and earth space communication links. Atmospheric losses have traditionally been estimated by calculating the contributions of individual weather phenomena through in-situ meteorological measurements and statistically derived models for estimating localized atmospheric water content. Collecting data for all points along the propagation path and calculating the physical effects of gases, clouds, and precipitation individually is both time consuming and impractical for large-scale use cases.

In response to these present limitations, this work proposes the use of novel deep learning models for estimating atmospheric losses from tabular meteorological sensor data and …

Effect Of Temperature And Rhenium Content In Precipitates On Dispersion Hardening Of Tungsten, Yulia R. Sharapova, Arseny M. Kazakov, Elena A. Korznikova, Alexandr Zinovev, Dmitry Terentyev, Sergey V. Dmitriev

Karbala International Journal of Modern Science

Tungsten (W) is being developed as a plasma-facing material for fusion reactors, where it is subjected to MeV neutron irradiation, low-energy helium isotope particles, and high temperatures. These conditions lead to the formation of point defects, dislocation loops, voids, and transmutation into rhenium (Re) and osmium (Os), which form precipitates that significantly impact dislocation motion and increase hardness. This study uses molecular dynamics modeling to examine the interaction between an edge dislocation and Re-rich particles of various stoichiometries, specifically coherent bcc-phase particles and noncoherent σ-phase precipitates. Results show that shear stress increases by approximately 20-40% with larger particle size (3-5 …

Gauss-Lobatto Method For Nuclear Reactivity Calculation, Daniel Suescún-Díaz, Luis E. Cardoso-Páez, Diego Peña-Lara

Okinawa Studies In Taiwan Under Japanese Rule: Focusing On The Use Of The Word “Nantō”, Takahiro Teshima

Kritika Kultura

In the modern period, certain research on Okinawa utilizing the noun “nantō,” which signified the southern islands, was known as Nantō studies. It accentuated Okinawa as the southernmost portion, or one component, of Japan, emphasizing Okinawa’s identity as a place that preserves old Japanese culture, based on the hypothesis that culture originates in the center of a cultural region and spreads to the frontier. This article examines the possibilities and limitations of Nantō studies in colonial Taiwan. Under the academic guidance at Taihoku Imperial University, including Japanese history, which had previously received less attention in prior research, Nantō studies could …

Broken Bengal: Tropes Of Conviviality And Fracture In Bangla Fiction, Maurice O'Connor

Kritika Kultura

This essay examines how Bangla fiction employs the trope of conviviality as a means to provide an affective understanding of the partition of Bengal. Of principal concern is how Bengali writers, regardless of their religious affiliation, insist upon the existence of a common Bengali across the religious divide. I open my essay with a brief historiographic introduction to the fracturing of Bengali society, contextualizing the backstories that are rarely fleshed out within Bangla fiction yet are elliptically present. Conviviality is the term I use to frame a common Bangla culture, and I explore the concept through Ivan Illich, Thomas Erikson …

Baroque Modernity And The Colonial World: Aesthetics And Catastrophe In Nick Joaquin’S A Portrait Of The Artist As Filipino, John D. Blanco

Kritika Kultura

The point of departure for these reflections is the status of “Hispanism” as an aesthetic mode (and possibly an elitist position or ideology in Philippine society) in a largely ignored debate within Philippine nationalist circles after World War II. In this instance, Dr. Blanco is thinking of the polemic between nationalist historian and poet Teodoro Agoncillo and Filipino national artist Nick Joaquin following the inauguration of a Philippine national republic formally recognized by the League of Nations. In this paper, he wants to focus on one, perhaps the key, manifestation of this "Hispanism" – Joaquin’s recovery of the baroque mode …

Controlled intracellular delivery of biomolecular cargo is critical for developing targeted therapeutics and cell reprogramming. Conventional delivery approaches (e.g., endocytosis of nano-vectors, microinjection, and electroporation) usually require time-consuming uptake processes, labor-intensive operations, and/or costly specialized equipment. Here, we present an acoustofluidics-based intracellular delivery approach capable of effectively delivering various functional nanomaterials to multiple cell types (e.g., adherent and suspension cancer cells). By tuning the standing acoustic waves in a glass capillary, our approach can push cells in flow to the capillary wall and enhance membrane permeability by increasing membrane stress to deform cells via acoustic radiation forces. Moreover, by coating …

Geosciences Faculty Publications

Analysis of PRISM and SNOTEL station data paired with USGS streamflow gage data in the western United States shows that, in snow-dominated mountainous watersheds, streamflow regimes differ between watersheds with karst geology and their non-karst neighbours. These carbonate aquifers exhibit a spectrum of flow paths encompassing karst conduits, including large fractures or voids that transmit water readily to springs and other surface waters, and matrix flow paths through soils, highly fractured bedrock, or porous media bedrock grains. A well-connected karst aquifer will discharge a large portion of its accumulated precipitation to surface water via springs and other groundwater flow paths …
