Using A Sand Tank Groundwater Model To Investigate A Groundwater Flow Model, Christopher Evrard, Callie Johnson, Michael A. Karls, Nicole Regnier

CODEE Journal

A Sand Tank Groundwater Model is a tabletop physical model constructed of plexiglass and filled with sand that is typically used to illustrate how groundwater water flows through an aquifer, how water wells work, and the effects of contaminants introduced into an aquifer. Mathematically groundwater flow through an aquifer can be modeled with the heat equation. We will show how a Sand Tank Groundwater Model can be used to simulate groundwater flow through an aquifer with a no flow boundary condition.

Process Optimization For Syngas Production From The Dry Reforming Of Methane Over 5ni+3sr/10zr+Al Catalyst Using Multiple Response Surface Methodology, Ahmed Al-Fatesh Dr., Mai H. Roushdy, Radwa El-Salamony Dr., Saba Alwan Dr., Ahmed Osman Dr., Sadeq Al-Faresh Dr., Hamid Ahmed Dr., Anis Fakeeha Dr., Ahmed Ibrahim Dr.

Chemical Engineering

5Ni+3Sr/10Zr+Al catalyst is synthesized using the impregnation method, characterized, and tested for dry reforming of methane. The influence of reaction temperature, feed ratio (CO2/CH4), and gas hour space velocity are examined using multiple response surface methodology through three factors in, a four-level central composite design. Second and higher-order regression models are applied to evaluate the interaction between the process parameters and responses. The results indicate that the reaction temperature is the most influential followed by the space velocity, while the feed ratio has a weak effect. The optimum values that maximize each of the response variables are found to be …

Applying The Sir Model: Can Students Advise The Mayor Of A Small Community?, Carrin Goosen, Mark I. Nelson, Mahime Watanabe

CODEE Journal

This is an account of a modelling scenario that uses the sir epidemic model. It was used in a third year applied mathematics subject. All students were enrolled in a mathematics degree of some type. Students are presented with the results of a test carried out on 100 individuals in a community containing 3000 people. From this they determined the number of infectious and recovered individuals in the population. Given the per capita recovery rate and making a suitable assumption about the number of infectious individuals at the start of the epidemic, they then estimate the infectious contact rate and …

Fluid Flow, Mineralization And Deformation In An Oceanic Detachment Fault: Microtextural, Geochemical And Isotopic Evidence From Pyrite At 13°30′N On The Mid-Atlantic Ridge, Andrew J. Martin, John W. Jamieson, Sven Petersen, Mostafa Fayek, Javier Escartin

Geoscience Faculty Research

Hydrothermal fluids in ultramafic-hosted hydrothermal systems associated with oceanic detachment faults can be more oxidizing compared to mafic-hosted vent sites. These fluids form a mineral assemblage of pyrite, magnetite and hematite. At 13°30′N on the Mid-Atlantic Ridge, chlorite-quartz breccias recovered from an exposed fault scarp contain pyrite, with abundant magnetite and hematite, indicating that the redox of the fluids was variable. In primary micron-scale zonations in pyrite, Ni, Co, and Se have a decoupled relationship, recording fluctuations in the chemical composition and temperature of hydrothermal fluid as the grains grew. Secondary zonations that erase and overprint primary zonations are limited …

Priority Skills For Engineers On The Island Of Ireland: Key Stakeholder Perceptions, Rosalind M Henry, Margaret Morgan, Una Beagon, Ruchita Jani, Janet Mckennedy, Brian Bowe

Reports

Executive Summary

Life on a shared island, in particular the island of Ireland (comprising Ireland and Northern Ireland), presents both challenges and opportunities, including for engineers tasked with addressing problems to help solve the SDGs that are indifferent to boundaries. Research demonstrates that (relative to current engineers) the engineer of the future will require a more diverse range of skills to navigate an increasingly complex work environment. Given this context, identification of relevant priority skills would therefore prove useful in focusing engineering educational initiatives.

Building on a European study (Beagon et al, 2022a) which identified at a European level the …

Designing A Convection-Cloud Chamber For Collision-Coalescence Using Large-Eddy Simulation With Bin Microphysics, Aaron Wang, Mikhail Ovchinnikov, Fan Yang, Silvio Schmalfuss, Raymond A. Shaw

Michigan Tech Publications

Collisional growth of cloud droplets is an essential yet uncertain process for drizzle and precipitation formation. To improve the quantitative understanding of this key component of cloud-aerosol-turbulence interactions, observational studies of collision-coalescence in a controlled laboratory environment are needed. In an existing convection-cloud chamber (the Pi Chamber), collisional growth is limited by low liquid water content and short droplet residence times. In this work, we use numerical simulations to explore various configurations of a convection-cloud chamber that may intensify collision-coalescence. We employ a large-eddy simulation (LES) model with a size-resolved (bin) cloud microphysics scheme to explore how cloud properties and …

Computer Science Faculty Research & Creative Works

The healthcare industry has transitioned from traditional healthcare 1.0 to AI-powered healthcare 4.0. However, overall cost for patient treatment remains high and challenging to manage due to the absence of a centralized cost evaluation mechanism before hospital visits. Therefore, in this paper, we devise a cloud-based mechanism to calculate hospitals' star rating based on questionnaire with the application of Z-score and K∗clustering algorithm. To evaluate disease severity at cloud, splitfed technique is utilized in coordination with Wireless Body Area Network (WBAN). Finally, the cloud calculates provisional treatment costs and finds a preferable hospital with a low payable treatment cost and …

Comment On 'From Counterportation To Local Wormholes', Justin Dressel, Gregory Reznick, Lev Vaidman

Mathematics, Physics, and Computer Science Faculty Articles and Research

Hatim Salih discovered a method for transferring a quantum state with no particles present in the transmission channel, which he named counterportation. Recently (Salih 2023 Quantum Sci. Technol.8 025016), he presented a feasible procedure for its implementation. The modification of the protocol by Aharonov and Vaidman, adopted by Salih, justifies the claim that no photons were present in the transmission channel during counterportation. We argue, however, that there is an error in this paper. The analysis of a simplified protocol, which questions the validity of the two-state vector formalism description of the photon presence in the communication channel, is …

Revisiting Robert Pagès: Documents And Culture, Michael K. Buckland

Proceedings from the Document Academy

An introduction to the life and work of Robert Pagès (1919–2007), French social psychology researcher and theorist of documentation. From 1946 to 1948 Pagès was a student in the program in documentation directed by Suzanne Briet that later became the Institut National des Techniques de Documentation (INTD). A 1947 thesis was published in 1948 as an article entitled “Transformations documentaires et milieu culturel” (Documentary transformations and cultural context). It received little attention until recently. The article, now reprinted and translated, examines the rise of new media and how they have largely displaced lived experience and bookish knowledge in a society …

In a context of uncertainty, organizations use creativity methods to anticipate future challenges in relations with the long-term evolutions of the society. These approaches consist in bringing together people with complementary points of view to multiply the diversity of ideas. This paper focuses on the process of transformation and selection of ideas and artifacts from a collective perspective in the unprecedented circumstances that occurred during the pandemic.

We question how ideas are grounded in the documents and artifacts produced at the key moments of the creative process from the perspective of the facilitators and the participants.

In this paper we …

Making-To-Be: Documents, Facta, And Material-Discursive Agency, Elliott Hauser

Proceedings from the Document Academy

This paper presents the performative analysis of agency within and surrounding documents as a path towards uniting the otherwise incompatible insights of both meaningcentric and materialcentric approaches. I contrast the terms agentical, providing agency, and agentic, possessing agency, to help clarify the apparent incompatibilities of prior approaches. I argue that a relational conception of agency, wherein the agentical/agentic distinction is blurred, preserves important virtues of both meaning and materialcentric approaches to documents. This paves the way for a unified materialdiscursive account of documents and a cure for document studies’ inherited duality malady. Extending prior work on capta (Drucker, 2011) and …

Integrating External Controls By Regression Calibration For Genome-Wide Association Study, Lirong Zhu, Shijia Yan, Xuewei Cao, Shuanglin Zhang, Qiuying Sha

Michigan Tech Publications

Genome-wide association studies (GWAS) have successfully revealed many disease-associated genetic variants. For a case-control study, the adequate power of an association test can be achieved with a large sample size, although genotyping large samples is expensive. A cost-effective strategy to boost power is to integrate external control samples with publicly available genotyped data. However, the naive integration of external controls may inflate the type I error rates if ignoring the systematic differences (batch effect) between studies, such as the differences in sequencing platforms, genotype-calling procedures, population stratification, and so forth. To account for the batch effect, we propose an approach …

Fish Assemblage Structure In Great Lakes Coastal Wetlands Over Ten Years, Matthew S. Silverhart

Masters Theses

Coastal wetlands in the Laurentian Great Lakes are important habitats for many fish species. The geographic scale of the watershed and the diversity of land uses in the region result in substantial environmental variation among coastal wetlands. During 2011-2020, annual surveys were conducted as part of the Great Lakes Coastal Wetland Monitoring Program (GLCWMP) to better understand the status and trends of coastal wetlands. Fish sampling consisted of fyke netting in monodominant vegetation zones. During this time, 1225 unique monodominant plant zones in coastal wetlands were sampled, resulting in 584,125 fishes captured that consisted of 113 different species. Yellow Perch …

Identification Of Faulty Sensor Nodes In Wban Using Genetically Linked Artificial Neural Network, Haider Rasheed Abdulshaheed, Mayasa M. Abdulrahman, Israa Ibraheem Al_Barazanchi, Jamal Fadhil Tawfeq

Iraqi Journal for Computer Science and Mathematics

Wireless Body Area Networks (WBANs) have risen as a promising innovation for checking human physiological parameters in real time. Be that as it may, the unwavering quality and precision of WBANs depend on the right working of sensor hubs. The distinguishing proof of defective sensor hubs is vital for guaranteeing the quality of information collected by WBANs. In this paper, we propose a novel approach to recognizing faulty sensor hubs in WBAN employing a hereditarily linked artificial neural organize (GLANN). The GLANN is preparedto employa crossbreedfuzzy-genetic calculation to optimize its execution in distinguishing defective sensor hubs. The proposed approach is …

Iraqi Journal for Computer Science and Mathematics

In this article, a projection type two step inertial iterative scheme for investigating set-valued quasivariational inequality in real Banach spaces is designed. We manifest the existence result and verified by an illustrativeexample. Also, we estimate the approximate solution of a set-valued quasi variational inequality by analyzing theconvergence of the proposed inertial iterative algorithm. Further, an extended Weiner-Hopf equation is consideredand substantiated that it is analogous to the extended set-valued quasi variational inequality. Finally, we investigatethe extended Weiner-Hopf equation by analyzing the convergence of the composed iterative scheme

Enrichment Of Polycyclic Aromatic Hydrocarbon Metabolizing Microorganisms On The Oral Mucosa Of Tobacco Users, James V. Defrancesco, Lin Tao, M Paul Chiarelli, Sylvia Pavlova, Antonia Kolokythas, Joel Schwartz, Benjamin Salameh, Stefan J. Green, Guy Adami

Chemistry: Faculty Publications and Other Works

Certain soil microbes resist and metabolize polycyclic aromatic hydrocarbons (PAHs). The same is true for a subset of skin microbes. In the human mouth, oral microbes have the potential to oxidize tobacco PAHs, thereby increasing these chemicals' ability to cause cancer of adjacent epithelium. We hypothesized that we could identify, in smokers, the oral mucosal microbes that can metabolize PAH. We isolated bacteria and fungi that survived long-term in minimal media with PAHs as the sole carbon source, under aerobic conditions, from the oral mucosa in 17 of 26 smokers and two of 14 nonsmokers. Of bacteria genera that survived …
