The Whispering Voices Behind The Poetry Of Robert Browning And Matthew Arnold: Three Theoretical Approaches To Selected Works: Formalist, Psychoanalytic, And Marxist, Gabriel M. Cisneros

Theses (2016-Present)

Throughout the literary world, many critics have attempted to pinpoint the root cause for the sudden changes in style and attitude about writing the poetry that ultimately chased Robert Browning and Matthew Arnold into developing their own style in which to convey their innermost compassion for humanity. They hid their injured poetic souls; they hid their innermost thoughts, but they expressed themselves through their characters. By expressing themselves as the voice behind the speaker, they were able to create an artificial mask and utilize the mask as a method of capitalizing on the very essence of what the dramatic monologue …

Exploring The Impact Of Negative Publicity And Organizational Justice Among Officers Of A Southwest Agency, Matthew J. Durán

Open Access Theses & Dissertations

Three years since the murder of George Floyd and police departments, nationwide, are amid a staffing crisis. While the outcomes of â??depolicingâ?? have received much empirical attention, little has been placed on understanding how officerâ??s attitudes were impacted, and how this affects their interactions with the public. This study uses survey data from a sample of 138 predominately Hispanic police officers to investigate the impact that negative publicity and organizational justice have on self-legitimacy (i.e., the confidence an officer has in their authority). Accordingly, multi-variate regressions are estimated to test the independent effects of negative publicity and organizational justice on …

Public Privacy And Info-Liberal Authoritarianism, Christopher Hongach

Dissertations, Theses, and Capstone Projects

Neoliberalism’s promise of economic prosperity has proven itself futile, as growing disparities in inequality have resulted in both developing and developed countries. As neoliberalism has become a major influence in international relations and the global economy, its adaptive capacity has led to the emergence of new forms and functions of capital, especially through commodification and abstract labor. With the rise of information capitalism, neoliberalism has incorporated information of all sorts into the nexus of capitalism. Most especially through the advancement of the Internet and social media platforms, information capitalism reaches its highest form through developing surveillance technology and the brokerage …

Post-Pandemic Travel Patterns Of Remote Tech Workers, Simon Tan, Kevin Fang, T. William Lester

Faculty Research, Scholarly, and Creative Activity

Almost half of all jobs in the San Francisco Bay Area are “remote-eligible” – more than any other metropolitan area in the United States, due to the high concentration of employees in the technology sector who were early to embrace teleworking at the start of the COVID-19 pandemic in early 2020. Any significant share of these tech workers staying remote may have profound long-term impacts on aggregate travel patterns in the region. This research seeks to predict the magnitude of these impacts and derive insights about the newly learned behaviors of tech workers, as indicative of remote-eligible workers in general. …

Animal tracking has afforded insights into patterns of space use in numerous species and thereby informed area-based conservation planning. A crucial consideration when estimating spatial distributions from tracking data is whether the sample of tracked animals is representative of the wider population. However, it may also be important to track animals in multiple years to capture changes in distribution in response to varying environmental conditions. Using GPS-tracking data from 23 seabird species, we assessed the importance of multi-year sampling for identifying important sites for conservation during the chick-rearing period, when seabirds are most spatially constrained. We found a high degree …

Search For Photons Above 1019ev With The Surface Detector Of The Pierre Auger Observatory, P. Abreu, M. Aglietta, I. Allekotte, K. Almeida Cheminant, A. Almela, J. Alvarez-Muñiz, B. Fick, D. Nitz, I. Norwood, A. Puyleart, Et Al.

Michigan Tech Publications, Part 1

We use the surface detector of the Pierre Auger Observatory to search for air showers initiated by photons with an energy above 1019 eV. Photons in the zenith angle range from 30° to 60° can be identified in the overwhelming background of showers initiated by charged cosmic rays through the broader time structure of the signals induced in the water-Cherenkov detectors of the array and the steeper lateral distribution of shower particles reaching ground. Applying the search method to data collected between January 2004 and June 2020, upper limits at 95% CL are set to an E-2 diffuse flux of …

An Intercomparison Of Large-Eddy Simulations Of A Convection Cloud Chamber Using Haze-Capable Bin And Lagrangian Cloud Microphysics Schemes, Fan Yang, Fabian Hoffmann, Raymond Shaw, Mikhail Ovchinnikov, Andrew M. Vogelmann

Michigan Tech Publications, Part 1

Recent in situ observations show that haze particles exist in a convection cloud chamber. The microphysics schemes previously used for large-eddy simulations of the cloud chamber could not fully resolve haze particles and the associated processes, including their activation and deactivation. Specifically, cloud droplet activation was modeled based on Twomey-type parameterizations, wherein cloud droplets were formed when a critical supersaturation for the available cloud condensation nuclei (CCN) was exceeded and haze particles were not explicitly resolved. Here, we develop and adapt haze-capable bin and Lagrangian microphysics schemes to properly resolve the activation and deactivation processes. Results are compared with the …

Constraining The Sources Of Ultra-High-Energy Cosmic Rays Across And Above The Ankle With The Spectrum And Composition Data Measured At The Pierre Auger Observatory, A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte, K. Almeida Cheminant, A. Almela, B. Fick, D. Nitz, I. Norwood, A. Puyleart, Et. Al

Michigan Tech Publications, Part 1

In this work we present the interpretation of the energy spectrum and mass composition data as measured by the Pierre Auger Collaboration above 6 × 1017 eV. We use an astrophysical model with two extragalactic source populations to model the hardening of the cosmic-ray flux at around 5 × 1018 eV (the so-called "ankle"feature) as a transition between these two components. We find our data to be well reproduced if sources above the ankle emit a mixed composition with a hard spectrum and a low rigidity cutoff. The component below the ankle is required to have a very soft spectrum …

Lead Scoring Using Low Code Ml Library, Ayad Aziz

Theses

Scoring leads manually can be time-consuming and ineffective because it relies on subjective criteria and human biases. On the other hand, automated lead scoring uses advanced algorithms to analyse large datasets and accurately predict a lead's potential value to the business. It provides valuable insights into customer behaviour and preferences that inform marketing and sales strategies. Machine learning algorithms are trained on historical sales data to identify patterns and correlations that indicate a lead's likelihood to convert. They consider variables like demographic information, web behaviour, and marketing engagement to generate a lead score that reflects the probability of converting into …

At an infiltrated refractive index (RI) of 1.35, 1.38, and 1.41, respectively, the maximal RI sensitivities of c-1 (channel-one), c-2 (channel-two), and …

Optimal Offering Strategy Of Genco With Joint Participation In Ftr Auction And Day-Ahead Market Considering Virtual Bidding, Hossein Mehdipourpicha, Rui Bo, Siyuan Wang

Electrical and Computer Engineering Faculty Research & Creative Works

Nodal price separations in Day-Ahead (DA) market caused by transmission congestion create congestion charges/surplus that are reallocated to the market participants through the financial transmission right (FTR) auction. From a market participant's viewpoint, these two markets are interrelated because the revenue of market participant in FTR auction is determined based on the day-ahead locational marginal prices. Furthermore, virtual transactions which are designed to improve price convergence between the day-ahead and real-time markets can directly impact day-ahead prices. This impact through virtual transactions may be utilized by a market participant to increase its FTR value and improve its overall strategy in …

Conventional wavemeters employ gratings, prisms, and other wavelength-sensitive devices in their design. Here, we report a simple and low-cost wavemeter based on a section of multimode fiber (MMF). The concept is to correlate the multimodal interference pattern (i.e., speckle patterns or specklegrams) at the end face of an MMF with the wavelength of the input light source. Through a series of experiments, specklegrams from the end face of an MMF as captured by a CCD camera (acting as a low-cost interrogation unit) were analyzed …

Machine Learning For A Vernier-Effect-Based Optical Fiber Sensor, Chen Zhu, Osamah Alsalman, Wassana Naku

Electrical and Computer Engineering Faculty Research & Creative Works

In recent years, the optical Vernier effect has been demonstrated as an effective tool to improve the sensitivity of optical fiber interferometer-based sensors, potentially facilitating a new generation of highly sensitive fiber sensing systems. Previous work has mainly focused on the physical implementation of Vernier-effect-based sensors using different combinations of interferometers, while the signal demodulation aspect has been neglected. However, accurate and reliable extraction of useful information from the sensing signal is critically important and determines the overall performance of the sensing system. In this Letter, we, for the first time, propose and demonstrate that machine learning (ML) can be …

Caspi: Collaborative Photon Processing For Active Single-Photon Imaging, Jongho Lee, Atul Ingle, Jenu V. Chacko, Kevin W. Eliceiri, Mohit Gupta

Computer Science Faculty Publications and Presentations

Image sensors capable of capturing individual photons have made tremendous progress in recent years. However, this technology faces a major limitation. Because they capture scene information at the individual photon level, the raw data is sparse and noisy. Here we propose CASPI: Collaborative Photon Processing for Active Single-Photon Imaging, a technology-agnostic, application-agnostic, and training-free photon processing pipeline for emerging high-resolution single-photon cameras. By collaboratively exploiting both local and non-local correlations in the spatio-temporal photon data cubes, CASPI estimates scene properties reliably even under very challenging lighting conditions. We demonstrate the versatility of CASPI with two applications: LiDAR imaging over a …
