Boundary Influence In Truncated Groundwater Models: Reconstructing A Local-Scale Modflow Model From A Consultant-Developed Regional Model In The Monterey Subbasin, Bruce K. Liscomb

Master's Theses

Regional groundwater models built by consultants contain valuable calibrated frameworks but are often too large and complex for repeated local-scale analysis. Rather than rebuilding an entirely new smaller model, this study truncates the existing consultant-built regional model of the Monterey Subbasin, preserving the original grid structure and parameter framework while reducing the active domain to a manageable size for planning-level use. A key finding is that boundary-condition representation exerted a dominant influence on simulated groundwater behavior within the truncated domain, highlighting that truncation is a structural decision that meaningfully affects how the model responds. Model performance was evaluated two ways. …

(R2133) Analysis Of A Bulk Queue With Balking, Adaptive Overloading Service, Multiple Vacation, Inspection And Rework, S. Karpagam, R. Lokesh

Applications and Applied Mathematics: An International Journal (AAM)

We consider a queueing system that utilizes a single server to manage product flow through bulk and overload service modes, depending on queue length. Balking occurs when the queue length reaches ‘N’. After completion of service, products undergo quality inspection, with defective products sent for rework based on specific probabilities. If the product is non-defective, the server continues processing until the queue length exceeds a certain threshold; beyond this point, the server is either routed back to bulk service or directed to an overload service. Also, the server goes into a vacation mode when the queue size is below a …

U.S. Regulation And Litigation Regarding Gmos: A Cautionary Tale Of A Piecemeal Framework, Michael R. Reese, George V. Granade

Northern Illinois University Law Review

Bioengineered crops using genetically modified organisms (GMOs or GM) are big business in the United States. In little more than two decades, GM agriculture constitutes more than 90% of crops such as corn, soy, and canola. The acceptance of GMO foods by consumers, however, has not been as robust—leading to demand for labeling regulations so consumers can identify whether their foods contain GMOs. U.S. law governing GMOs, particularly food labeling, lacks a comprehensive regulatory scheme and is instead highly fragmented. The Food and Drug Administration (FDA) has debated how to label such foods for over a decade, issuing no rules …

Nothing Runs Like A Deere, Except When Deere Doesn’T Run: Why Illinois Should Enact Right-To-Repair Legislation For Its Farmers, John Aird

Northern Illinois University Law Review

Since 1971, John Deere has been using the popular slogan “Nothing Runs Like a Deere,” symbolizing the strength and self-reliance long associated with American farming. Yet as modern agricultural equipment has become more computerized and complex, manufacturers such as John Deere have restricted farmers’ ability to independently repair the equipment they own, through the use of unattainable software, licensing agreements, digital locks, and warranty limitations. The modern right-to-repair movement challenges this shift. At its core, the movement asserts that ownership should include the ability to repair the product that a consumer owns. This article argues that Illinois should enact a …

Physics-Informed Machine Learning-Aided Framework For Entrainment Fraction In Gas-Liquid Two-Phase Annular Flow, Anadi Mondal, Subash L. Sharma

Nuclear Engineering and Radiation Science Faculty Research & Creative Works

The liquid film flow rate or droplet flow rate in annular flow is determined by a parameter known as the entrainment fraction. Conventional empirical correlations are commonly employed for predicting the entrainment fraction; however, their applicability is often restricted to specific operating conditions and working fluids. Recently, a few machine learning (ML) models have been developed to achieve better accuracy in entrainment fraction prediction. However, these models are completely data-driven, meaning they are good for prediction in the interpolated domain, but exhibit limited generalization capability in the extrapolated domain. To address this limitation, a physics-informed machine learning-aided framework (PIMLAF), combining …
