Proof Of Concept: Using Uas Technology To Accomplish Aerial Roof Inspections, Madison R. Fanning

Theses and Dissertations

With the growing use of simulation across industries, the digital twin remains an underexplored research area, particularly in emergency management and response. Its real-time updating capability is often overlooked due to the misconception that "digital twin" is merely a complex term for simulation. This paper highlights its distinctiveness through an evasion exercise involving two independent entities in a collocated environment. Using a highly integrated virtual environment (HIVE) and internet of things (IoT) devices, we link the physical system with an analytical simulation, demonstrating the impact of lag times in high-pressure scenarios. The computational model leverages agent-based modeling (ABM) and discrete-event …

Drivers Of Vegetation Structure Differ Between Proposed Natural Reference Conditions For Temperate Europe, Elena A. Pearce, Charles W. Davison, Florence Mazier, Signe Normand, Ralph Fyfe, Maria Antonia Serge, Paolo Scussolini, Jens Christian Svenning

School of Geography, Earth and Environmental Sciences

Aim: Pre-degradation baseline conditions (references) provide crucial context for restoration actions. Here, we compare vegetation structure and its driving processes across the main pre-agricultural references discussed for temperate Europe: the Last Interglacial and the early-mid Holocene—before and after the arrival of Homo sapiens, respectively. Location: Temperate Europe. Time Period: The first ~4000–6000 years, excluding the initial early-successional phases, of the Last Interglacial (PAAZ III) and Holocene (8700–5700 BP). Major Taxa Studied: Plants. Methods: We use large datasets of pollen-based vegetation reconstructions (REVEALS) to compare open vegetation, light woodland and closed forest between the two periods. We use Random Forest modelling …

Quantifying Teaching Quality In University Chemistry Using Bipolar Neutrosophic Decision-Making Framework, Lina Sun, Feng Yi

Neutrosophic Sets and Systems

There is no doubt that the teaching of university Chemistry plays a critical role in enriching the students’ knowledge with analytical and problem-solving skills that are necessary for achieving academic and professional progress in many fields. However, the process of evaluating the quality of Chemistry teaching remains a challenging task because it usually relies on subjective judgments, diversity of criteria, and variability in human perception, leading to inherent uncertainty. Bipolar Neutrosophic Sets (NS) provide appropriate representation for uncertainty setting ls with three levels of membership, each with positive and negative degrees. Inspired by that, this study contributes to the body …

Exploring The Dynamics Of Lotka-Volterra Systems: Efficiency, Extinction Order, And Predictive Machine Learning, Sepideh Vafaie, Deepak Bal, Michael A.S. Thorne, Eric Forgoston

School of Computing Faculty Scholarship and Creative Works

For years, a main focus of ecological research has been to better understand the complex dynamical interactions between species that comprise food webs. Using the connectance properties of a widely explored synthetic food web called the cascade model, we explore the behavior of dynamics on Lotka-Volterra ecological systems. We show how trophic efficiency, a staple assumption in mathematical ecology, affects species extinction. With clustering analysis, we show how straightforward inequalities of the summed values of birth, death, self-regulation, and interaction strengths provide insight into which food webs are more enduring or stable. Through these simplified summed values, we develop a …

Perceived And Recorded Temperature In Aircraft Cabins During 143 Flights, Matthew Nicholls, Peter Vink

Journal of Aviation Technology and Engineering

This essay reports on the perceived and recorded temperature in aircraft cabins during 143 flights. In each flight, passengers reported their experience. They recorded temperature and humidity after boarding and one hour later. The reports show that fewer than half of the passengers perceived the temperature as “good.” Most passengers (39%) perceived it as hot, and some (17%) perceived it as cold. Comparing the temperatures with guidelines shows that 18% of the recorded temperatures in the cabin were empirically too hot and 2% empirically too cold. The differences between passengers in what they perceive as a good temperature are large, …

Abstract Urban areas are foci for the introduction of non-native plant species, and they often act as launching sites for invasions into the wider environment. Although interest in biological invasions in urban areas is growing rapidly, and the extent and complexity of problems associated with invasions in these systems have increased, data on the composition and numbers of non-native plants in urbanized areas remain scattered and idiosyncratic. We assembled data from multiple sources to create the Global Urban Biological Invasions Compendium (GUBIC) for vascular plants representing 553 urban centres from 61 countries across every continent except Antarctica. The GUBIC repository …

A Long-Term Study Of Algal Blooms In Alexandria's Ecosystems: A Review, Samia K. Mikhail, Wagdy Labib

Blue Economy

Coastal ecosystems in Alexandria are facing significant stress, primarily due to the intrusion of discharged wastewaters of different origins. Over the past three decades, there has been a noticeable increase in the occurrence of harmful algal blooms (HABs) across Alexandria marine, brackish, and freshwater environments. Unfortunately, the situation is deteriorating, and HABs have become chronic issues characterized by frequent occurrences of various causative species. This phenomenon has spread widely affecting previously uninfected coastal areas with high frequency and diverse patterns of occurrence. This article provides an overview of the state of visible HABs associated with incidents of fish and/or invertebrate …

Multiple Hypothesis Testing Under Dependence, Nabaneet Das

Doctoral Theses

We have examined various aspects of multiple hypothesis testing under dependence. Traditional algorithms designed to control the error arising from multiplicity become severely conservative when the hypotheses exhibit positive dependence, resulting in a loss of power. There is a paucity of literature explicating the behaviour of traditional algorithms when the hypotheses are dependent. In the realm of multiple testing, a popular multiplicity correction is the Bonferroni correction, which is perhaps the oldest classical approach for controlling the Family-Wise Error Rate (FWER) at a desired level, regardless of dependence among hypotheses. However, under the global null and equicorrelated normal model, the …

Tenacious Resins And Residues: Oil Propaganda In Architectural Digest During The Energy Crises Of The 1970s, Banafsheh Mohammadi

The Goose

Architectural Digest was first published in 1920 by John C. Brasfield, a California-based publisher. In 1933, the magazine was purchased by Condé Nast and has since become a popular design magazine, particularly in North America, known for its visually vibrant and abundant advertisements. Car advertisements are among the most recurring ads featured in the magazine. Through an archival investigation of Architectural Digest magazines from 1973 to 1983, I investigate how, if at all, car advertisements in the magazine reflected the 1973 and 1979 oil crises.

The 1979 global energy crisis was a period of high energy prices and supply …

Video Poem: What Remains, Edie Steiner

The Goose

What Remainsis a three-minute poetry film I created to address the issue of “becoming-with” (Wright 2014). In the film, I document two large-scale, public-art spectacles I witnessed in Toronto, as historical markers of collective becoming-with. I contrast super-8mm film footage of the 1984 outdoor public performance “Shibola” at the Bell Trinity Square building in Toronto, by the Japanese Butoh dance group Sankai Juku, with digital video of “A Tribute to Toronto,” Judy Chicago’s 2022 Smoke Sculpture on the Toronto waterfront. I then intercut these images with digital recordings of ruins and relics, both ancient and modern, merging as …

The Sedimentological Signature Of Impact Spherules And Its Relation To Ejecta Transport Mechanisms During The Chicxulub Asteroid Impact (Cretaceous/Paleogene Boundary), Hermann D. Bermúdez, Liliana Bolívar, José A. Arz, Ignacio Arenillas, Vicente Gilabert, Robert Depalma, George Phillips, Daniela Bermúdez, Maurizia De Palma, Clemencia Gómez, Ying Cui

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Chicxulub impact is the most likely cause of the Cretaceous/Paleogene boundary (KPB) mass extinction and the only impact event in Earth's history with a globally traceable ejecta bed. Although the impact spherules are thought to represent molten or vaporized material, precise genesis and transport mechanisms remain underconstrained. Here, we show that the morphology, size, internal structure, and distribution of the spherules within the KPB deposits are related to origin and transport processes. The study of thousands of spherules from KPB deposits in Colombia, the USA, and Spain has revealed the presence of three fractions related to three different distribution …

Promoting Equity: Embracing Food Justice In The Transformation Of The Food Systems For Bipoc Communities, Frank Yeboah Adusei

Journal of Extension

The food justice movement addresses systemic food inequities impacting BIPOC communities, rooted in civil rights and environmental justice movements. It advocates for fair access to culturally relevant food, combating food deserts, and promoting food sovereignty. Recognizing intersectionality, it emphasizes collaboration to dismantle systemic barriers. This study aims to understand BIPOC communities' challenges and effective strategies, stressing the importance of collaborative efforts for lasting systemic change. Extension professionals face challenges but can contribute through equity-focused strategies, community engagement, and partnerships, advancing food justice and fostering inclusive food systems.

Beer And Biology, A Perfect Pairing: Using Beer To Spread Awareness About Invasive Species, Samuel Nutile, Adam Simpson, Sara Stahlman, Lynne E. Beaty

Journal of Extension

Managing the spread of introduced invasive species relies on educating recreationists that currently or potentially harbor such species. By partnering with a local brewery, we developed the Lagers for Lakes Draft Series to facilitate outreach about aquatic invasive species in Erie, Pennsylvania. To date, Lagers for Lakes drafts and associated launch events have reached over 230 individuals and increased awareness of invasive species by 86%. With the materials provided here and the lessons learned from these events, we hope similar outreach efforts can be developed elsewhere to educate and minimize the spread of invasive species.
