Unlocking Lean Construction: Decoding The Root Causes Of Initial Implementation Failures, Adam Hoots

All Theses

In recent years, the construction industry has increasingly adopted lean construction methodologies, with the aim of enhancing project efficiencies, eliminating waste, and delivering projects that exceed all project owner expectations. With this as the industry’s focus, many projects struggle with the initial implementation of lean principles, leading to disrespect of people and resources, cost overruns, schedule delays, stakeholder misalignment, and compromised quality. This research investigates the reasons behind initial failures and how they influence the broader industry's perception of lean construction.

Drawing from a comprehensive case study of a higher education dormitory and dining facility project, this research study explores …

Designing And Building An Action Figure Of Alexander The Great To Better Engage Young Learners In History, Patrick Sandoval

All Theses

This paper discusses creating an action figure of Alexander the Great as a means of garnering a child’s interest in a specific setting of human history. Physical mediums have merit as supplemental tools for traditional learning methods for children, with action figures providing an outlet for role-playing and enhanced engagement. Topics include the significance of Alexander the Great, as well as the process of creating an action figure of him using production methods of digital character sculpting and 3D printing. Its design takes inspiration from the Street Fighter series, Classical and Hellenistic Greek sculpture, and professional wrestling action figures.

Unsupervised Moving Object Segmentation With Atmospheric Turbulence, Dehao Qin

All Theses

Moving object segmentation in the presence of atmospheric turbulence is a highly challenging task due to the irregular and time-varying distortions induced by the atmospheric turbulence. This thesis presents an unsupervised approach for segmenting moving objects in videos affected by such atmospheric turbulence. The proposed methodology is grounded in a detect-then-grow scheme: the algorithm begins by identifying a small set of moving object pixels (seed points) with high confidence and progressively expanding a foreground mask from these seed points to segment all moving objects. The proposed approach capitalizes on rigid geometric consistency across video frames to disentangle different types of …

Texas Panicum (Urochloa Texana (Buckley) R.D.Webster) Management In South Carolina Peanut (Arachis Hypogaea L.) Production, Alexis Clobas-Celiz

All Theses

Texas panicum (TP) is a persistent weed in South Carolina peanut fields, challenging growers with its season-long emergence and the limited availability of effective mid- to late-season herbicide options. Residual herbicides typically applied within 40 days of planting, fail to control late-emerging TP cohorts, making postemergence (POST) herbicides like clethodim and imazapic essential for managing this weed. Clethodim efficacy, however, depends on the TP growth stage and environmental conditions during application. To optimize control, this research evaluated clethodim applied at various TP growth stages (5 to 60 cm) and with different adjuvants. Clethodim was applied singly or in sequence, with …

Shifting Perspectives With Procedural Modeling Techniques And Vertex Animated Textures For Real-Time Interactive Morphing, Stephanie Schulze

All Theses

As humans experience reality, they intake external stimuli using sensory receptors to process information, forming a perception. Perceptions are subjective and shape each individual’s reality. Naturally then, by changing one’s perceptions, their experience of reality is altered, for better or worse. To emphasize the idea that perception is malleable and encourage a mindset of questioning alternative ways to look at a situation, an interactive experience in Unreal Engine is developed where a dull cityscape morphs and transforms into a surreal oversized nature scene. Procedural modeling techniques are used to create a variety of morphing assets, while Vertex Animated Textures are …

Plasticity Characterization Of Sheet Metals Using Torsional In-Plane Shear Testing, Matthew Eaton

Master's Theses and Capstones

In the field of sheet metal forming, it is important to accurately model the plastic stress-strain behavior of materials for use in simulations. Various tests are performed to characterize the plastic behavior, such as plastic anisotropy and strain hardening, which is used to identify material parameters of constitutive models. Shear testing in particular is an area of increasing interest in metal forming applications due to significantly larger strain level compared to uniaxial tension. This thesis aims to design a torsional in-plane shear testing fixture, to characterize the strain hardening and plastic anisotropy in shear for DDQ and DP980 steel sheets, …

Carceral Apartheid: Centering State Responsibility For The Racial Order, Ion Meyn

Cardozo Law Review

Racial harms are often attributed to private ordering. But the power of White communities to subordinate communities of color is not a constellation of private acts independent of state violence. When scrutinized, acts of racial exclusion, segregation, and violence persist to the extent they are aligned with the political order and backed by the state’s violent guarantee. The knowledge that any resistance to these acts will be met with state retribution bristles in the background.

There are different ways in which state violence produces and reproduces the racial order: (1) direct violence; (2) a violent guarantee backing communal acts of …

Lung Ct Image Segmentation Using Vgg-16 Network With Image Enhancement Based On Bounded Turning Mittag-Leffler Function, Ali M. Hasan, Mohammed Khalaf, Bayan M. Sabbar, Rabha W. Ibrahim, Hamid A. Jalab, Farid Meziane

Baghdad Science Journal

Automated segmentation of diseases considered a necessary initial step in routine diagnosis. Lung diseases that affect the lungs, such as pneumonia or lung collapse can result in areas of consolidation or atelectasis, where lung tissue becomes denser or collapses. It can be challenging to accurately segment such areas, as they may exhibit similar characteristics to adjacent structures. This study proposes a lung CT image segmentation method which includes two steps: (1) a new image enhancement model that uses the bounded turning Mittag-Leffler function to improve the CT images for better segmentation outcomes. (2) a new modified VGG-16 for infection of …

Baghdad Science Journal

During a diazotization coupling reaction, an azo dye-ligand (H4L) was formed by combining 3-aminophenol and 2,4,6-trihydroxyacetophenone. This ligand was then allowed to react with several different metal ions (Mo (VI), Fe (III), Co (II), Cr (III), Ru (III) and Rh (III)), forming stable metal complexes with various geometries. The binding of the azo-dye group to the metal ions was detected through the M-N and M-O absorption bands in Fourier-transform-infrared, which indicated the involvement of nitrogen and oxygen. LC-MS spectra confirmed the molecular weights of the ligand and its complexes, and elemental analysis was also conducted. Electronic spectra were used to …
