Effect Of Heat Input On Microstructure And Mechanical Properties Of Submerged Arc Welded Sm570-Tmc Steel, Toni Yuhandri, Winarto Winarto, Diana Natalia
Journal of Materials Exploration and Findings (JMEF)
SM570TMC is high-strength steel (HSS), which is commonly used in structures that require higher-strength components. In this research, submerged arc welding (SAW)-welded SM570 TMC steels' microstructure and mechanical characteristics were examined. SM570 plates with 12mm thickness were multi-pass welded by using a 3.0 mm diameter of ESAB OK Autrod 13.40 (AWS A5.23: EG) filler metal. The joint design is a single V multi-pass butt weld with a backing strip. Two welded joints were prepared by using heat inputs of 2.2 and 2.9 kJ/mm. The microstructures of two welded joints were observed by using optical microscopy and scanning electron microscope (SEM). …

Graphite: Open Source 2d Graphics Editor, Christopher H. Mendoza, Oliver A. Dolan
Computer Science and Software Engineering
Graphite is an open source 2D graphics editor aiming to provide a useful alternative to the Adobe product suite while integrating modern ideas from research and industry, including a node-based procedural approach that makes the design process fully non-destructive. Tools from the VFX and gamedev industry like Nuke, Houdini, and Substance Designer have proven the power and flexibility of node-based systems, but they are each lacking in their user experience because of the deep level of complexity that is not abstracted into simpler concepts for users (Adobe Systems, SideFX, The Foundry Visionmongers Ltd., n.d.). Graphite puts the node-based core into …

An Engineering Approach For Evaluating The Lifetime Experience Of Sex Trafficking Victimization, Kimberly Starr Nagulpelli
Dissertations
This research is an original approach that applies industrial engineering and operations research tools to the sociological problem of sex trafficking victimization. Such an approach enables quantitative evaluation of the impacts on an individual’s lifetime by anti-trafficking efforts and public policies.
A fully interconnected, lifetime model for the experience of sex trafficking victimization is defined as the result of a comprehensive review of literature. Beginning with victimization risk, the defined model is an anticipatory tool to understand the incidences and consequences to individuals during their lifetime. This research develops the model further into a Discrete-Time Markov Chain (DTMC) with definitions …

Enabling The Integration Of Sustainable Design Methodological Frameworks And Computational Life Cycle Assessment Tools Into Product Development Practice, Tejaswini Chatty
Dartmouth College Ph.D Dissertations
Environmental sustainability has gained critical importance in product development (PD) due to increased regulation, market competition, and consumer awareness, leading companies to set ambitious climate targets . To meet these goals, PD practitioners (engineers and designers) are often left to adapt their practices to reduce the impacts of the products they manufacture. Literature review and interviews with practitioners show that they highly valued using quantitative life cycle assessment (LCA) results to inform decision making.
LCA is a technique to measure the environmental impacts across various stages of a product life cycle. Existing LCA software tools, however, are designed for dedicated …

Identifying Key Activity Indicators In Rats' Neuronal Data Using Lasso Regularized Logistic Regression, Avery Woods
Honors Theses
This thesis aims to identify timestamps of rats’ neuronal activity that best determine behavior using a machine learning model. Neuronal data is a complex and high-dimensional dataset, and identifying the most informative features is crucial for understanding the underlying neuronal processes. The Lasso regularization technique is employed to select the most relevant features of the data to the model’s prediction. The results of this study provide insights into the key activity indicators that are associated with specific behaviors or cognitive processes in rats, as well as the effect that stress can have on neuronal activity and behavior. Ultimately, it was …

Automating Lackenby's Method: The Design Of A Set Of Scripts To Execute Lackenby's Method With Mcnaull's Expansion In Rhinoceros 3d, Mara E. Kramer
University of New Orleans Theses and Dissertations
In vessel design, modifying the design of a preexisting hull is a common practice to save time and labor compared to designing a hull from scratch. This can be achieved either by manually adjusting the hull model in a 3D modeling software or by systematically adjusting certain vessel parameters using an algebraic method. However, these methods are time-intensive and do not fully utilize the capabilities of modern software. To address this issue, this paper presents a set of Rhinoscript and Python scripts that automate part of the hull modification process using Lackenby’s method with McNaull’s expansion. The developed code utilizes …
