Modeling, Optimization And Uncertainty Quantification Of Solids-Based Co2 Capture Technologies, Anca Ostace Jan 2021

Modeling, Optimization And Uncertainty Quantification Of Solids-Based Co2 Capture Technologies, Anca Ostace

Graduate Theses, Dissertations, and Problem Reports (ETD)

Solids-based carbon dioxide (CO2)adsorption, where CO2 is adsorbed under high pressure/low temperature and desorbed at low pressure/high temperature, is a low energy consumption capture technology with high carbon uptake efficiency. Chemical looping combustion (CLC), where a solid oxygen carrier (OC) transports oxygen between two high-temperature reactors – a fuel and an air reactor –, is a low energy penalty, fuel-flexible technology with inherent CO2 capture for power/heat and syngas production.

In this work, state-of-the-art equation-oriented (EO) mathematical models of a fixed-bed (FxB) contactor for CO2 adsorption and moving-bed (MB) reactors for gas-, and solid-fueled CLC …


Identification And Classification Of Radio Pulsar Signals Using Machine Learning, Di Pang Jan 2021

Identification And Classification Of Radio Pulsar Signals Using Machine Learning, Di Pang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Automated single-pulse search approaches are necessary as ever-increasing amount of observed data makes the manual inspection impractical. Detecting radio pulsars using single-pulse searches, however, is a challenging problem for machine learning because pul- sar signals often vary significantly in brightness, width, and shape and are only detected in a small fraction of observed data.

The research work presented in this dissertation is focused on development of ma- chine learning algorithms and approaches for single-pulse searches in the time domain. Specifically, (1) We developed a two-stage single-pulse search approach, named Single- Pulse Event Group IDentification (SPEGID), which automatically identifies and clas- …


Supporting Student Success And Persistence In Stem With Active Learning Approaches In Emerging Scholars Classrooms, David Miller, Jessica Deshler, Tim Mceldowney, John Stewart, Edgar Fuller, Matt Pascal, Lynnette Michaluk Jan 2021

Supporting Student Success And Persistence In Stem With Active Learning Approaches In Emerging Scholars Classrooms, David Miller, Jessica Deshler, Tim Mceldowney, John Stewart, Edgar Fuller, Matt Pascal, Lynnette Michaluk

Faculty & Staff Scholarship

Over the last several decades, Emerging Scholars Programs (ESPs) have incorporated active learning strategies and challenging problems into collegiate mathematics, resulting in students, underrepresented minority (URM) students in particular, earning at least half of a letter grade higher than other students in Calculus. In 2009, West Virginia University (WVU) adapted ESP models for use in Calculus I in an effort to support the success and retention of URM STEM students by embedding group and inquiry-based learning into a designated section of Calculus I. Seats in the class were reserved for URM and first- generation students. We anticipated that supporting students …


Fertilization And Tree Species Influence On Stable Aggregates In Forest Soil, Jacob E. Kemner, Mary Beth Adams, Louis M. Mcdonald, William T. Peterjohn, Charlene N. Kelly Jan 2021

Fertilization And Tree Species Influence On Stable Aggregates In Forest Soil, Jacob E. Kemner, Mary Beth Adams, Louis M. Mcdonald, William T. Peterjohn, Charlene N. Kelly

Faculty & Staff Scholarship

Abstract: Background and objectives: aggregation and structure play key roles in the water-holding capacity and stability of soils and are important for the physical protection and storage of soil carbon (C). Forest soils are an important sink of ecosystem C, though the capacity to store C may be disrupted by the elevated atmospheric deposition of nitrogen (N) and sulfur (S) compounds by dispersion of soil aggregates via acidification or altered microbial activity. Furthermore, dominant tree species and the lability of litter they produce can influence aggregation processes. Materials and methods: we measured water-stable aggregate size distribution and aggregate-associated organic matter …


Credit Cards, Credit Utilization, And Consumption, Scott Fulford, Scott Schuh Dec 2020

Credit Cards, Credit Utilization, And Consumption, Scott Fulford, Scott Schuh

Economics Faculty Working Papers Series

Credit bureau data show remarkably stable consumer utilization of unsecured debt over the business cycle, life cycle, and individually quarter-to-quarter, despite massive variation in available credit. To explain these new findings, we propose a life-cycle consumption model with heterogeneous preferences, endogenous payment choice, and the option to revolve debt for consumption smoothing. Using diary data to identify payment use, the estimated model matches consumption and credit use at every frequency and suggests that around half the population has an endogenously high marginal propensity to consume. The results suggest understanding credit availability and heterogeneous use may lead to richer counter-cyclical policies.

China’S Illegal Organ Trade: From Executed Prisoners To Organ Tourism To Falun Gong, Adrienne Thompson Nov 2020

China’S Illegal Organ Trade: From Executed Prisoners To Organ Tourism To Falun Gong, Adrienne Thompson

West Virginia University Historical Review

As worldwide populations continue to rise, the constant necessity for life-saving organs for terminally and chronically ill patients has become extremely vital and profitable to medical centers across the globe. Since China’s preliminary debut in the international organ donation and transplantation system in the late 1960s, various scholars, journalists, and health professionals across the globe have demonstrated outright shock at the massive influx and seemingly endless supply of transferable organs emanating from Chinese transplant centers and hospitals. Investigations have shown that China has been actively harvesting organs from recently executed prisoners and incarcerated Falun Gong practitioners. Regardless of numerous outside …


Determining The Impact Of The Anabaptists Using Bullinger’S Propaganda Strategies In Von Dem Unverschampten Fräfel, Jovanna Shirky Nov 2020

Determining The Impact Of The Anabaptists Using Bullinger’S Propaganda Strategies In Von Dem Unverschampten Fräfel, Jovanna Shirky

West Virginia University Historical Review

Many scholars of the Reformation contend that the Anabaptist movement did not significantly impact the society of its day. However, my analysis of Heinrich Bullinger’s anti-Anabaptist work Von dem unverschampten fräfel, ergerlichem verwyrren unnd unwarhafftem leeren der selbsgesandten Widertöuffern indicates that the Anabaptists did pose a significant threat to the socioreligious structures that both the mainstream Reformation and Catholicism endorsed. By analyzing Bullinger’s propaganda strategies within the work, I find that the beliefs and practices of the Anabaptists challenged the most basic structures of society, thus alarming Bullinger and others who opposed the movement. Bullinger’s language within the work and …


Development Of Surrogate Hand For Impact Tests, Trevor A. Brison, Eduardo M. Sosa Nov 2020

Development Of Surrogate Hand For Impact Tests, Trevor A. Brison, Eduardo M. Sosa

Mountaineer Undergraduate Research Review

Despite continuous advancements in technology and safety procedures, hand injuries are still a significant problem in many industries. Metacarpal gloves are often used by workers to protect their hands against impacts, cuts, and other hazards. Importantly, testing the level of impact protection offered by different designs of metacarpal gloves cannot be done with living subjects. This limitation requires the use of a surrogate hand which can be used consistently and systematically in controlled impact tests. This work focuses on the development of a surrogate hand which can be manufactured and used for this purpose. The surrogate hand developed in this …

Commodities Are Not Industries! A Value Chain Example, Randall W. Jackson, Patricio Aroca Oct 2020

Commodities Are Not Industries! A Value Chain Example, Randall W. Jackson, Patricio Aroca

Regional Research Institute Working Papers

Leontief and Stone both received Nobel Prizes in Economics for development and extension of input-output (IO) analysis, a framework that has gained little traction in mainstream U.S. economics. Although IO modeling has gained renewed focus in several problem domains, many contemporary economists eschew Stone's enhancements, resulting in inconsistent analytics, even in top economics journals. In this paper, we use an increasingly common approach to value chain analysis as one example that demonstrates such conceptual misunderstandings and by presenting properly formulated alternatives, we demonstrate the extent of the consequences of neglecting the Stone enhancements and important role of reproducing results.


The Political Economy Of Vermont’S Abortion Bill, Shishir Shakya, Elham Erfanian, Alexandre R. Scarcioffolo Oct 2020

The Political Economy Of Vermont’S Abortion Bill, Shishir Shakya, Elham Erfanian, Alexandre R. Scarcioffolo

Regional Research Institute Working Papers

Public choice literature divides the rationality of voting between instrumental and expressive. In this paper, we take the Vermont legislature in passing the H. 57 bill as a case to explain some of the determinants of expressive voting empirically. The H.57 bill declares that no government entity can interfere with, or restrict, a consenting individual’s right to abortion care across the entire gestation period. However, the bill has not changed the previously states quo of the state towards abortion rights. Thus, it creates a situation in which we can analyze the legislator’s voting behavior through the lens of expressive voting …


Extending The Macroeconomic Impacts Forecasting Capabilities Of The National Energy Modeling System, Christa D. Court, Randall W. Jackson, Justin Adder, Gavin Pickenpaugh, Charles Zelek, Amanda J. Harker Steele Oct 2020

Extending The Macroeconomic Impacts Forecasting Capabilities Of The National Energy Modeling System, Christa D. Court, Randall W. Jackson, Justin Adder, Gavin Pickenpaugh, Charles Zelek, Amanda J. Harker Steele

Regional Research Institute Working Papers

To comprehensively model the macroeconomic impacts that result from changes in long-term energy-economy forecasts, the United States Department of Energy’s National Energy Technology Laboratory (NETL) partnered with West Virginia University’s (WVU) Regional Research Institute to develop the NETL/WVU econometric input-output (ECIO) model. The NETL/WVU ECIO model is an impacts forecasting model that functions as an extension of the U.S. energy-economic models available from the United States (U.S.) Energy Information Administration’s National Energy Modeling System (NEMS) and the U.S. Environmental Protection Agency’s Market Allocation (MARKAL) model. The ECIO model integrates a macroeconomic econometric forecasting model and an input-output accounting framework along …

Teaching With Digital 3d Models Of Minerals And Rocks, Graham Dm Andrews, Gabrielle Labishak, Sarah Brown, Shelby L. Isom, Holly Danielle Pettus, Trevor Byers Oct 2020

Teaching With Digital 3d Models Of Minerals And Rocks, Graham Dm Andrews, Gabrielle Labishak, Sarah Brown, Shelby L. Isom, Holly Danielle Pettus, Trevor Byers

Faculty & Staff Scholarship

The disruption to geoscience curricula due to the COVID-19 pandemic highlights the difficulty of making mineral and rock samples accessible to students online rather than through traditional lab classes. In spring 2020, our community had to adapt rapidly to remote instruction; this transition amplified existing disparities in access to geoscience education but can be a catalyst to increase accessibility and flexibility in instruction permanently. Fortunately, a rich collection of 3D mineral and rock samples is being generated by a community of digital modelers (e.g., Perkins et al., 2019).


Consistent Regional Commodity-By-Industry Input-Output Accounts, Randall Jackson, Péter Járosi Sep 2020

Consistent Regional Commodity-By-Industry Input-Output Accounts, Randall Jackson, Péter Járosi

Regional Research Institute Working Papers

A long-standing regional science problem domain focuses on the identification of structural economic change. One of several approaches relies on the use of historical final demand series and a comparison of observed industry output to an estimate of what output would have been were economic structure static. However, these methods were first developed before the introduction of today’s commonly used commodity-by-industry (CxI)input-output (IO) accounting frameworks, and before the application of these methods to regional economies. Correctly formulating the supporting accounting structures for these analyses is essential, but can be challenging even for experienced an- alysts. Related textbook and journal articles …


Spatial Transportation Modeling, Christian Werner Sep 2020

Spatial Transportation Modeling, Christian Werner

Web Book of Regional Science

Transportation modeling is both one of the valuable job skills offered by scientific geography and a topic that can serve to develop analytic intuition. This book is designed for the student receiving a first exposure to the transportation problem as well as an introduction to the formal modeling of geographic phenomena. Transportation modeling is a good and particularly useful example of the sharing of paradigms and methodologies between scientific geography and other sciences. Professor Christian Werner’s geographical approach should be of particular interest to students and followers of the literature not only in human geography but also in operations research, …


Spatial Autocorrelation, John Odland Sep 2020

Spatial Autocorrelation, John Odland

Web Book of Regional Science

The analysis of spatial distributions and the processes that produce and alter them is a central theme in geographic research and this volume is concerned with statistical methods for analyzing spatial distributions by measuring and testing for spatial autocorrelation. Spatial autocorrelation exists whenever a variable exhibits a regular pattern over space in which its values at a set of locations depend on values of the same variable at other locations. Spatial autocorrelation is present, for example, when similar values cluster together on a map. Spatial autocorrelation statistics make it possible to use formal statistical procedures to measure the dependence among …

Point Pattern Analysis, Barry N. Boots, Arthur Getls Aug 2020

Point Pattern Analysis, Barry N. Boots, Arthur Getls

Web Book of Regional Science

Points on a map can represent many important phenomena, including towns, stores and centers for shopping, industrial locations, parks, archaeological sites, plant and animal species, the home site of a person with a possible environmentally related disease, and so on. The authors introduce readers to the general analysis of the location of points on maps. Map patterns are assumed to result from one or more spatial processes in the human or physical world. Often the causal forces are known, but more frequently, researchers seek to identify them. The analysis of the spatial pattern of the phenomena under study can be …


Input-Output Analysis: A Primer, 2nd Ed., Randall W. Jackson Aug 2020

Input-Output Analysis: A Primer, 2nd Ed., Randall W. Jackson

Web Book of Regional Science

Input-output (IO) analysis is a modeling framework that records the business transactions in an economy over a given time period. It is used in any number of ways, all of which are intended to improve our understanding of how industries in an economy are interrelated. The economy under study can be a national economy, a multi-state, state, or multi-county regional economy. As its name suggests, the IO accounting framework describes and depicts the input and output relationships of all industries in an economy. The utility of the IO framework is manifold. Most immediately, the inter-industry transactions table, or input-output matrix, …

Professional Sporting Events Increase Seasonal Influenza Mortality In Us Cities, Alexander Cardazzi, Brad Humphreys, Jane E. Ruseski, Brian P. Soebbing, Nicholas Watanabe Jun 2020

Professional Sporting Events Increase Seasonal Influenza Mortality In Us Cities, Alexander Cardazzi, Brad Humphreys, Jane E. Ruseski, Brian P. Soebbing, Nicholas Watanabe

Economics Faculty Working Papers Series

The COVID-19 pandemic shut down sporting events worldwide. Local policy makers and league officials face important decisions about restarting play, especially in professional leagues that draw large numbers of spectators to games. We analyze the impact of professional sporting events on local seasonal influenza mortality to develop evidence that will help inform sports league reopening policy decisions. Results from a difference-in-differences model applied to data from a sample of US cities that gained new professional sports teams over the period 1962-2016 show that the presence of games in these cities increased local influenza mortality by between 4% and 24%, depending …
