Water Hammer Protection For Pumped Turnouts On Aging Pipelines, Charles M. Burt, Zachary C. Markow

BioResource and Agricultural Engineering

Water hammer in an irrigation district pipeline is typically caused by sudden changes in turnout flow rates. A sudden shutoff of a booster pump, or a rapid closure of a turnout valve, can potentially cause surge damage. The problem occurs if the pressure exceeds the pressure rating of the pipeline. As pipes age, their pressure rating typically declines. This report describes three different solutions that utilize a combination of these techniques/devices to provide district pipeline protection from water hammer.

Lateral Deformation Behavior Of Mass Timber Beam To Column Gravity Connection, Tyler James Williams

Civil and Environmental Engineering Master's Project Reports

A beam-to-column connection consisting of glulam beam and column and cross laminated timber floor slab was developed and experimentally evaluated for use in buildings that are expected to undergo earthquake-­­induced lateral drift. The connection utilized a passive gap closure mechanism designed to allow beam rotations during lateral drift while minimizing residual separation between the beam and the column following an earthquake. Full scale cyclic experiments were used to validate the connection’s minimal rotational stiffness and demonstrate low damage performance for lateral drifts exceeding 4.5% drift. The connection exhibited no degradation in gravity load capacity throughout the imposed lateral deformations. An …

Exploring The Relationship Of Bikeshare And Transit In The United States Of America, David Rafael Soto Padín

Civil and Environmental Engineering Master's Project Reports

Bicycling and bike-share have been growing in US cities as transportation alternatives.

The (Re) Adaptability Of Research Methodologies In The Instructional Design & Technology Field, Enilda Romero-Hall, E-Ling Hsiao, Fei Gao

Visual Communications and Technology Education Faculty Publications

In its revolutionary piece, On The Origin of Species, Darwin (1859) provided compelling evidence for the existence of the natural selection process. He described how species interact with their environments to cause variations in traits. Just like the species that Darwin explored in his research, the methodologies used in investigations related to the instructional design and technology (IDT) field have (re)adapted. This (re)adaptability serves to help us better inquire and explore the landscape of formal and informal educational learning environments available today.

Wireless Sensors For Health Monitoring Of Marine Structures And Machinery, Francisco David Rojas Calvente

PhDs

Remote structural and machinery health monitoring (SMHM) of marine structures such as ships, oil and gas rigs, freight container terminals, and marine energy platforms can ensure their reliability. However, the wired sensors currently used in these applications are difficult and expensive to install and maintain. Wireless Sensor Networks (WSN) can potentially replace them but there are significant capability gaps that currently prevent their long-term deployment in the harsh marine environment and the structurally-complex, compartmentalised, all-metal scenarios with high volume occupancy of piping, ducting and operational machinery represented by marine structures. These gaps are in sensing, processing and communication hardware and …

Using Synthetic Lethality To Sensitize Pediatric Brain Cancer Cells To The Dna Damaging Effects Of Radiation Therapy, Megan Ruckman, Rose Nelson, Forrest Kievit

UCARE: Research Products

Brain tumors are the leading cause of cancer related deaths in children. As a treatment, radiotherapy is very effective, but it also comes with many severe side effects, such as radiation-induced adverse developmental and psychosocial effects.² Cancer, because it is a mutagenic disease, is by definition a disease of DNA repair pathways. Here we utilize drugs to inhibit various DNA repair pathways with the purpose of sensitizing cancer cells to radiotherapy so that lower doses may be used. Hopefully this would improve the lifelong outcomes of patients that would otherwise not survive or would be left with lifelong neurocognitive …

Structural Transformations In Porous Glasses Under Mechanical Loading. I. Tension, Nikolai V. Priezjev, Maxim A. Makeev

Mechanical and Materials Engineering Faculty Publications

The evolution of porous structure and mechanical properties of binary glasses under tensile loading were examined using molecular dynamics simulations. We consider vitreous systems obtained in the process of phase separation after a rapid isochoric quench of a glass-forming liquid to a temperature below the glass transition. The porous structure in undeformed samples varies from a connected porous network to a random distribution of isolated pores upon increasing average glass density. We find that at small strain, the elastic modulus follows a power-law dependence on the average glass density and the pore size distribution remains nearly the same as in …

Automated Impact Response Sounding For Accelerated Concrete Bridge Deck Inspection, Jacob Lynn Larsen

Theses and Dissertations

Infrastructure deterioration is an international problem requiring significant attention. One particular manifestation of this deterioration is the occurrence of sub-surface cracking (delaminations) in reinforced concrete bridge decks. Of many techniques available for inspection, air-coupled impact-echo testing, or sounding, is a non-destructive evaluation technique to determine the presence and location of delaminations based upon the acoustic response of a bridge deck when struck by an impactor. In this work, two automated air-coupled impact echo sounding devices were designed and constructed. Each device included fast and repeatable impactors, moving platforms for traveling across a bridge deck, microphones for air-coupled sensing, distance measurement …

Methods For Creating Rigid Foldability In Origami-Inspired Deployable Mechanisms, Alden Daniel Yellowhorse

Theses and Dissertations

Because origami has proved to be a tremendously rich source of inspiration in engineering, interest in solving some of the challenges that affect origami-inspired design has been significant. One such challenge involves ensuring that origami-inspired mechanisms are rigid-foldable or capable of moving without requiring links to bend or distort. Because rigid-foldability is essential in mechanisms that are constructed using rigid materials, access to methods of engineering this characteristic are highly desirable. This research addresses this need by developing methods for the design of origami-inspired mechanisms that are rigid-foldable. Methods for modifying crease patterns to achieve this are described and compared. …
