Analysis Of Applied Modifications To A Cone Penetration Test-Based Lateral Spread Displacement Prediction Model, Alexander Edward Corob

Theses and Dissertations

This study set out to examine the effectiveness and reliability of six modifications to the Zhang et al. (2004) CPT-based lateral spread model. A regression analysis, distribution charts, and a discriminant analysis are performed to determine how effective the modifications are on the model. From the comparisons and statistical analysis performed in this study, application of these modifications reduces over-predictions from strain-based prediction methods. Unfortunately, the tendency to under-predict displacements on average is also increased.

The Heterogeneity And Change In The Urban Structure Of Metropolitan Areas In The United States, 1990–2010, Stefan Leyk, Deborah Balk, Bryan Jones, Mark R. Montgomery, Hasim Engin

Publications and Research

While the population of the United States has been predominantly urban for nearly 100 years, periodic transformations of the concepts and measures that define urban places and population have taken place, complicating over-time comparisons. We compare and combine data series of officially-designated urban areas, 1990–2010, at the census block-level within Metropolitan Statistical Areas (MSAs) with a satellite-derived consistent series on built-up area from the Global Human Settlement Layer to create urban classes that characterize urban structure and provide estimates of land and population. We find considerable heterogeneity in urban form across MSAs, even among those of similar population size, indicating …

The Effects Of Oil Viscosity And Water Vapor Temperature On Droplet Condensation In Lubricant-Infused Surfaces, Michael Lorberg, Jianxing Sun, Patricia Weisensee

Mechanical Engineering and Materials Science Independent Study

This experiment is meant to measure the effects of oil viscosity and water vapor temperature on the nucleation rate of droplets on lubricant-infused surfaces. To accomplish this, three different lubricants with a range of viscosities were used. Each lubricant was placed on top on a glass stage with a coating of Glaco, a superhydrophobic surface coating, to create the lubricant-infused surface. The surface was then placed on top of a cold stage in order to cool the sample. Then, hot water vapor was blown over the surface of the sample so that it could condense to form droplets on the …

Nothing Is Over: Ftca Claims For Toxic Torts On Native Lands, Jessica Ditmore

American Indian Law Journal

In 1976, Congress passed the Resource Conservation and Recovery Act (“RCRA”) to curtail the growing problem of disposing of hazardous waste and toxic substances generally. Decades prior, Congress established the Federal Tort Claims Act (“FTCA”) to hold the federal Government liable for tortious conduct the same way a private citizen would be. The federal government assumed the responsibility to ensure the wellbeing of Native Nations (“NN”). This is commonly referred to the “Trust Doctrine.” This duty stems from the settlement of Native American lands, and a recognition of the treaties entered into by the United States with a “moral [obligation] …

Ransomware Is Quietly Devastating American Healthcare Facilities, Benjamin Powers

Capstones

The patient didn’t attract any attention initially. They were just one more cog moving through the system that was the massive hospital complex on your average day. That was, until they were shown to a room, and left alone. At that point, they removed a flash drive from their pocket and tried to insert it into a computer — with the goal of accessing the hospitals computer systems.

This is according to the Chief Information Security Officer at a major Northwest university hospital system, who asked for anonymity due to the sensitive nature of such attacks.

More Than A Century After Problem Emerged, Manhole Explosions Still Injuring Dozens In New York City, Gaspard Le Dem, Gabriel Sandoval

Capstones

Since the early days of electrification, New York City has been rattled by manhole explosions –– underground blasts that injure residents, damage buildings, force evacuations, cause power outages and traffic disruptions.

Consolidated Edison, the city's largest electric provider, has for decades blamed manhole issues on bad weather and road salt that erodes underground wires. But some experts and former utility workers say lack of maintenance is at the root of the problem.

Meanwhile, city and state officials have failed to rein in the problem through weak laws and loose oversight. As a result, unsuspecting drivers and pedestrians continue to be …

Flood Dynamics In The Portland Metropolitan Area, Past, Present, And Future, Lumas Terence Helaire

Dissertations and Theses

The Portland area has an extensive flood history since it was founded in 1845. In the late 19th century, the Portland area was prone to flooding from snowmelt freshets (3-6 months duration) and brief winter rain or rain-on-snow events. Since that time the magnitude of spring freshets has been curtailed by 45% due to climate change, flow diversions, and reservoir management. Along with changes in hydrology, the bathymetry of the Lower Columbia River has been altered by the dredging of the navigation channel, diking, and land reclamation. To understand how these changes in hydrology and bathymetry have affected tidal and …

The resistance of the pCdTe films is ρ ≈ 102÷103Оm • sm, the thickness is d ≈ 70÷100 μm. An n-type SnO2 layer was deposited by magnetron-ion sputtering. The photosensitive structure pCdTe-TeO2-n SnO2 can be widely used as sensors for detecting X-ray and gamma radiation.

Crazy Rich Karachi — Where The Streets Are Paved With Gold, Murtaza Irfan Ali

MSJ Capstone Projects

Karachi happens to be Pakistan’s economic powerhouse but the irony is it never received its fair share of development. Which is why, to this day, I have no clue where to park, when I visit the southern district of the city. The random and sporadic parking has costed me with a hundred scratches and 2 pairs of side-view mirrors during the course of a year. So to find exactly where I could safely and “legally” park, I set out to find some answers.

Beavers Alter Stream Macroinvertebrate Communities In Northeastern Utah, Susan E. Washko, Brett B. Roper, Trisha Brooke Atwood

Watershed Sciences Faculty Publications

1. Understanding changes in macroinvertebrate communities is important because they play a large role in stream ecosystem functioning, and they are an important food resource for fish. Beaver‐induced changes to stream morphology could alter macroinvertebrate communities, which in turn could affect food webs and ecosystem function. However, studies investigating the effects of North American beaver activities on macroinvertebrates are rare in the inter‐mountain west, an area with high potential for beaver‐assisted restoration.
2. The aim of this study was to quantify differences in the macroinvertebrate community between unaltered segments of streams and within beaver ponds in north‐eastern Utah, U.S.A. We assessed macroinvertebrate …
