Characteristics Of Refractivity And Sea State In The Marine Atmospheric Surface Layer And Their Influence On X-Band Propagation, Douglas Matthew Pastore

Electronic Theses and Dissertations

Predictions of environmental conditions within the marine atmospheric surface layer (MASL) are important to X-band radar system performance. Anomalous propagation occurs in conditions of non-standard atmospheric refractivity, driven by the virtually permanent presence of evaporation ducts (ED) in marine environments. Evaporation ducts are commonly characterized by the evaporation duct height (EDH), evaporation duct strength, and the gradients below the EDH, known as the evaporation duct curvature. Refractivity, and subsequent features, are estimated in the MASL primarily using four methods: in-situ measurements, numerical weather and surface layer modeling, boundary layer theory, and inversion methods.

The existing refractivity estimation techniques often assume …

Environment, Communication And Decision For Multiagent Systems, Lu Zhao

Electrical Engineering Dissertations - Archive

ABSTRACT: Multiagent systems (MAS) are ubiquitous in modern systems and have found broad applications, such as in intelligent transportation systems (ITS). Environment, communication and decision are among the essential components of MAS. The realistic environment in which MAS operates is usually stochastic, and its modeling, identification and estimation are important to consider. The communication in MAS is also critical for decisions. For example, in ITS, to improve travel efficiency and reduce traffic accidents, scheduling schemes for Vehicle-to-Everything (V2X) communication need to be developed. MAS decisions also need to be robust to uncertainties. For example, in mixed-traffic autonomous driving, the decisions …

Converging And Diverging Outcomes Of Posttraumatic Growth (Ptg) And Posttraumatic Depreciation (Ptd) In Combat Veterans: A Case Study, Dayton Williams

Social Work Theses - Archive

Upon examining combat veterans’ psychological responses to combat-related trauma, two emerged for consideration: posttraumatic growth (PTG) through making meaning out of a traumatic experience and a positive outcome or change, and posttraumatic depreciation (PTD) an inability to make meaning of a traumatic experience and a negative outcome or change. Understanding how PTG and PTD converge, diverge, and impact an individual is crucial in supporting a veteran’s journey to health and well-being. A comparative study of the cases of two Marine combat veterans who served during OEF/OIF offers numerous similarities: both are in the millennial cohort; both are part of a …

Monitoring Wise Civilization By Creating An Index, Andrew Targowski

Comparative Civilizations Review

The Wise Civilization Index will assess how wise we are in developing and living in a sustainable civilization.

Recently, people have started to worry about the state of the climate. This has been reflected in the finding that the climate temperature should be kept to a growth of below two degrees Celsius by 2100 to save our species from a slow death (The Paris Agreement of 2015). After all, raising the human body temperature by two degrees threatens illness and even death by four degrees. The same (relatively) can be done with Earth. However, apart from the climate, the problem …

Buber The Radical Egalitarian And Buber And Psychology, Kenneth Feigenbaum

Comparative Civilizations Review

My first iteration for this paper was to present Martin Buber in the context of radical politics in Germany and to focus upon his relationship to the anarchist Gustav Landauer. After a brief search, I found too few sources that were easily accessible from here in the United States, so as part of this presentation I situate Buber in the radical politics extant mostly during his time in Germany and in Berlin. I focus here on Buber’s psychology but include several intellectual side trips visiting aspects of Buber’s philosophy and his politics. I cannot separate them in discussing Buber and …

Investigating And Characterizing Septin Cellular Regulators During Infection Related Development In M. Oryzae, Rinalda Proko

Graduate Theses and Dissertations

The fungus Magnaporthe oryzae causes a devastating disease of rice and wheat, called blast, which poses a major threat to food security across the planet. To enter plant tissue, M. oryzae produces a remarkable pressure-generating infection cell called an appressorium, which mechanically ruptures the tough cuticle of host leaves through the application of enormous physical force directed onto a narrow penetration structure emerging from its base. Importantly, appressorium form and functionality depends on the regulated assembly of a toroidal ring-like structure, composed of septins, which forms within its base. Septins are a family of membrane-associated GTP-binding proteins that polymerize into …

Localization And Identification Of Emi Sources In Shielding Enclosures Based On A Two-Step Source Reconstruction Method, Zi An Wang, Jun Fa Mao, Li (Lijun) Jun Jiang, Ping Li

Electrical and Computer Engineering Faculty Research & Creative Works

Localization and identification of unknown electromagnetic interference (EMI) sources in shielding enclosures is a great challenge due to the complex electromagnetic environment. In this work, a two-step source reconstruction method is proposed to address this issue. The actual EMI sources are initially modeled by equally distributed equivalent electric dipoles in the shielding enclosure. Effects of surrounding environments are rigorously incorporated using the numerical Green's function which bridges between the equivalent dipoles and planar scanned tangential magnetic near-field. Next, the initial equivalent sources are downsized via evaluating the contribution of each equivalent dipole. The parameters of remaining equivalent dipoles are updated …

A Direct Data Approach To Joint 2-D Doa And Frequency Estimation With L-Shaped Array, Yanming Zhang, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

This article presents a joint two-dimensional dynamic mode decomposition (JTDDMD) approach to estimate the azimuth angle, elevation angle, and frequency for multiple narrowband sources using the L-shaped array. According to the placement position of different coordinate axes of the receiving antenna in the array, i.e., x- or z-axis, the received signal is divided into two datasets. Two-dimensional dynamic mode decomposition (TDDMD), the sub algorithm of JTDDMD, is used twice to deal with these two datasets separately. Through the analysis of the x-axis subarray received signal using TDDMD, the electrical angle in the x-direction and frequency are obtained with automatic pairing. …
