The U.S. Bureau of Transportation Statistics conducts a nationwide census of ferry boat operators for the U.S. Department of Transportation and the collected information is used for statistical purposes. The Caltrans Division of Local Assistance has been asked by the Federal Highway Administration (FHWA) to gather data regarding ferry operations under MAP-21, the Moving Ahead for Progress in the 21st Century Act. MAP-21 includes a new formula program for ferry boats and ferry terminal facilities eligible under 23 USC 129(c) which authorizes federal participation in toll roads, bridges, tunnels, and ferries. FHWA has asked that Caltrans assure the ferry boat …

Measuring Walking And Cycling Using The Pabs (Pedestrian And Bicycling Survey) Approach: A Low-Cost Survey Method For Local Communities, Ann Forsyth

Mineta Transportation Institute

To tackle the problems of greenhouse gas emissions, traffic congestion, resident quality of life, and public health concerns, communities are using initiatives to spur more walking and cycling. As local governments face hard choices about which programs to fund, decision makers, planners, and residents seek to understand if proposed policies to increase bicycling and walking—modes referred to as “active travel”— actually work. However, most communities have unreliable means to know how many active travel trips occur in their jurisdictions, let alone how the numbers may change over time. This project developed a low-budget survey method and related sampling strategy for …

Smart-Grid: Technology And The Psychology Of Environmental Behavior Change, Stephanie M. Stern

Chicago-Kent Law Review

There is a schism in the legal scholarship between scholars who argue that value, norm, and information campaigns can induce pro-environmental behavior and those who contend that structural, psychological, and social forces sharply constrain behavior change. Both sides of this debate have neglected the critical and ever-increasing role of technology in addressing residential pollution. The example of electricity "smart grids" illustrates how technology engineered to override cognitive and behavioral limitations can comprehensively reduce household consumption and emissions. Electricity conservation suffers from multiple barriers to collective action, including large numbers of geographically dispersed polluters, low financial payoffs, and, the contribution of …

The Legal-Political Barriers To Ramping Up To Hydro, Dan Tarlock

Chicago-Kent Law Review

Hydroelectric energy is the oldest major source of non-carbon, renewable energy and is the only conventional renewable resource in the current energy mix. Increased hydro capacity would seem to be a key element of any United States energy policy designed to promote the greater use of renewable resources. However, for several decades hydro has been perceived as a mature, fully developed technology. This article argues that any effort to stimulate substantial new hydro capacity will face a series of environmental legal and policy constraints. Efforts to adapt to global climate change will further complicate efforts to increase hydro electric generation. …

Green Diesel: Finding A Place For Algae Oil, Fred Bosselman

Chicago-Kent Law Review

The prospect of obtaining domestically-produced biodiesel from algae has attracted wide investor interest. Although many analysts predict that economic production is five to ten years away, the production process involves such a wide range of environmental and land use issues that it is not premature to begin thinking about the kinds of places in which "green biodiesel" could be efficiently made in the United States. Our land use and environmental laws were all drafted by people who never imagined the possibility that huge volumes of algae would be an important energy resource; nor could they have known that the location …

Analysis Of Single And Dual Under-Expanded, Rarefied Jets, Wenhai Li

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

A numerical study, using the Direct Simulation Monte Carlo (DSMC) approach, of the interaction effects between two identical sonic under-expanded nitrogen jets under rarefied conditions is reported. In this paper, the effects of the jet stagnation Knudsen number (Kn_s), the ratio of the stagnation-to-background pressure (P_s/P_b), and the distance between the jet orifices (L/D) were investigated for a range of these parameters. The background pressure has a very significant effect on the physics of flow, and the interactions between the two jets affect the location of the Mach disks for both the primary and …

Contributions Of The Inhibitor Of Kappa B Kinases (Ikks) In Macrophages And Neutrophils After Francisella Tularensis Live Vaccine Strain (Lvs) Infection., Sylvia Samaniego

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The immune system is a complex network of cells regulated by a number of signaling pathways to drive specific host defenses against invading pathogens. The NF-&kappaB (nuclear factor of the kappa light chain enhancer in B cells) family of inducible transcription factors is a critical regulator of many innate and adaptive immune responses. NF-&kappaB activation by several receptors converges upon two upstream kinases, IKK&alpha and IKK&beta, that regulate gene induction. Many studies report that IKK&beta is the critical kinase involved in NF--&kappaB activation, although at a transcriptional level, both kinases are needed to obtain the full spectrum of gene induction. …

Tools To Enrich User Experience During"Visual Analysis", Supriya Garg

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Visual Analytics is the integration of interactive visualization with analysis techniques to help answer questions, and find interesting"patterns" in a given dataset. This approach is useful in cases where human knowledge and intuition is required. Further, with the increasing size of data, an interactive visual interface can give the user control over what she wants to see. Towards this end, we develop a Visual Analytics (VA) infrastructure, rooted on techniques in machine learning and logic-based deductive reasoning. This system assists people in making sense of large, complex data sets by facilitating the generation and validation of models representing relationships in …

Of Nesting Dolls And Trojan Horses: A Survey Of Legal And Policy Issues Attendant To Vehicle-To-Grid Battery Electric Vehicles, Bryan Lamble

Chicago-Kent Law Review

2010 will not be remembered as the year when the domestic energy landscape changed, dominated as it was by environmental catastrophe and human calamity and tragedy caused by the search for and extraction of traditional fossil fuels. In fact, clean(er) energy and greater efficiency seem, in some ways, to be less of a reality at the beginning of the second decade of the twenty-first century than many would have predicted (and hoped). Furthermore, a contentious mid-term election season (stoked by fears of massive deficits, rising national debt and ballooning government) dominated the headlines at the expense of what could prove …

Biotech Biofuels: How Patents May Save Biofuels And Create Empires, Adam Wolek

Chicago-Kent Law Review

The United States' primary transportation energy sources are fossil fuels, namely, gasoline and diesel. These products have high environmental, security, and financial costs. A strong emphasis has been placed on biofuels, especially ethanol and biodiesel, to lessen reliance on fossil fuels. Historically, high production costs, lack of infrastructure, return on investment anxieties, and concerns about scaling-up production have slowed the development of these alternative technologies. Today, biotechnological solutions are lowering productions costs and making large scale production more economically feasible. Patents can lessen anxieties about investment as they can provide longer-term protection and market exclusivity for patented technologies. As biofuels …

Undergraduate Honors Capstone Projects

In an age where training and knowledge are easily accessible online, textbooks, lecture slides and other class materials have migrated to online programs. Online programs are becoming easier to maintain for professors and administrators and offer some convenience and efficiency that traditional classroom lectures do not. It is widely assumed that students who have grown up with cell phones, email accounts, social media, iPods, Google and laptops easily identify with internet based applications. This research studies a group of over 30 university students seeking to develop skill-­‐sets to prepare them for entering the workforce through participation in an online and …

Toward The Validation Of Depth-Averaged, Steady-State Simulations Of Fluvial Flows Using Three-Dimensional, Steady-State, Rans Turbulence Models, Pedro Abdiel Mateo Villanueva

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Calculations of fluvial flows are strongly influenced by geometry complexity and large overall uncertainty on every single measurable property, such as velocity and shear. Moreover, a considerable portion of the data obtained from computational simulations arose from two-dimensional, steady-state models. The present work states a different approach to perform computer-based simulations and analyze fluvial flows. For the first part, the suitability of OpenFOAM to be used as the main CFD solver to analyze fluvial flows is studied. Initially, two well documented channel configurations are computationally studied using OpenFOAM. Finally, these results are compared to the output obtained from one of …

An Evolutionary Approach To Optimization Of Compound Stock Trading Indicators Used To Confirm Buy Signals, Allan W. Teeples

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis examines the application of genetic algorithms to the optimization of a composite set of technical indicator filters to confirm or reject buy signals in stock trading, based on probabilistic values derived from historical data. The simplicity of the design, which gives each filter within the composite filter the ability to act independently of the other filters, is outlined, and the cumulative indirect effect each filter has on all the others is discussed. This system is contrasted with the complexity of systems from previous research that attempt to merge several indicator filters together by giving each one a weight …

Incorporating Spatial Information Into Gas Plume Detection In Hyperspectral Imagery, Cameron S. Grant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Detection of chemical plumes in hyperspectral data is a problem having solutions that focus on spectral information. These solutions neglect the presence of the spatial information in the scene. The spatial information is exploited in this work by assignment of prior probabilities to neighborhood configurations of signal presence or absence. These probabilities are leveraged in a total probability approach to testing for signal presence in a pixel of interest. The two new algorithms developed are named spatial information detection enhancement (SIDE) and bolt-on SIDE (B-SIDE). The results are explored in comparison to the clutter matched filter (CMF), a standard spectral …

Destructive Testing And Finite-Element Modeling Of Full-Scale Bridge Sections Containing Precast Deck Panels, Travis R. Brackus

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Full-depth, precast panel deck systems are becoming more common in bridge installation and repair. The objective of these systems is to achieve the performance of cast-in-place systems while simultaneously saving time and money. The structural behavior of these systems has been the subject of scrutiny in recent research. The Utah Department of Transportation demolished a steel I-girder bridge containing a precast panel deck system and provided two full-scale specimens for this project. Destructive testing was performed at Utah State University on the specimens to investigate three failure modes: flexural, beam shear, and punching shear. Finite-element models were created using ANSYS …

Safety Evaluation Of Work Zone Practices In Utah, Tomás Ernesto Lindheimer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Work zones present a risk to drivers and to personnel constructing the roadway. In 2005 work zones accounted for 2.5% of fatalities nationwide, 3.5% for the state of Utah. The goal of this research is to make work zones safer by quantifying the risk that they present to drivers. The approach of this research has been to review part 6 of the Manual of Uniform Traffic Control Devices (MUTCD) and compare the differences from the 2003 and 2009 editions, conduct field studies of Utah work zones, and develop a tool for measuring risk in work zones. In the 2009 MUTCD …

Architecture, Modeling, And Analysis Of A Plasma Impedance Probe, Magathi Jayaram

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Variations in ionospheric plasma density can cause large amplitude and phase changes in the radio waves passing through this region. Ionospheric weather can have detrimental effects on several communication systems, including radars, navigation systems such as the Global Positioning Sytem (GPS), and high-frequency communications. As a result, creating models of the ionospheric density is of paramount interest to scientists working in the field of satellite communication.

Numerous empirical and theoretical models have been developed to study the upper atmosphere climatology and weather. Multiple measurements of plasma density over a region are of marked importance while creating these models. The lack …

Assessment Of Ruminal Fermentation Characteristics Of Condensed Tannin-Containing Forages Using Continuous Cultures, Christina Marie Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two independent studies were conducted to assess the effects of feeding condensed tannin (CT)-containing forages to continuous cultures to evaluate their impacts on ruminal fermentation and digestibility, with an emphasis on methane (CH4) and ammonia-N (NH3-N) production. In Chapter 3, treatments consisted of: 1) 100% alfalfa hay (AH), 2) 50% AH and 50% birdsfoot trefoil hay (dry matter (DM) basis; AHBFTH), and 3) 100% birdsfoot trefoil hay (BFTH). Three replicated runs lasted 8 d each, with the first 5 d allowed for microbial adaptation to the diets, and 3 d for data collection and sampling. Methane, neutral detergent fiber (NDF) …

Transportation Network Resiliency: A Fuzzy Systems Approach, Nayel Urena Serulle

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Every day the dependence on transportation grows as local, regional, national, and international independence increases. Resilient transportation systems are needed to secure the highest possible level of service during disruptive events, including natural and man-made disasters. Because of limited resources, decision makers need guidance on how, when, and where to invest to improve resiliency of their networks. The research objective is to develop a method to assess and quantify resiliency, at pre-event conditions, using a fuzzy inference approach. This research expands previous work, refining key variable definitions, adjusting model interactions, and increasing transparency between metrics. This thesis presents the method …

Estimating And Verifying Household Potential To Conserve Water, Francisco J. Suero

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This thesis identifies impacts of behaviors and technology on residential indoor water use and conservation efforts. We use pre-existing detailed end-use data collected before and after toilets, faucets, showerheads, and clothes washers were retrofitted in 96 owner-occupied, single-family households in Oakland, California; Seattle, Washington; and Tampa, Florida between 2000 and 2003.

Water volume, duration of use, and time of use were recorded and disaggregated by appliance for two weeks before and four weeks after appliances were retrofitted. For each appliance, we compare observed differences in water use before and after retrofits to water savings predicted by analytical engineering, semi-analytical engineering, …

Correspondence Of Job-Preference And Job-Matching Assessment With Job Performance And Satisfaction Among Youth With Developmental Disabilities, Julie Hall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the effects of job preference and job match on job performance among four 19-to 20-year-old young adults with developmental disabilities placed in community-based job conditions. Prior studies have examined the effects of job preference on community-based job performance without the job-matching component. The researcher identified high-preference, high-match and low-preference, low-match job conditions and tasks using a video web-based assessment program. Each participant was subsequently placed in a randomized sequence of 30-min sessions on one high-preference, high-match job condition performing a preferred task and one low-preference, low-match job performing a non preferred task. Job coaches instructed and prompted …

Walking Biomechanics Of End Stage Knee Oa And Tka Patients., Danielle Biton

Electronic Theses and Dissertations

Osteoarthritis (OA) of the knee is associated with decline in functional capacity and ultimately leads to Total Knee Arthroplasty (TKA) in many of these patients. Exercise regimens prior to surgery may potentially enhance pre and post TKA functional performance. However, assessment of such performance should involve biomechanical factors that characterize the mechanisms with which tasks are performed, and not just the quantity of task performed. The present overall study investigated walking biomechanics of end stage knee OA and TKA patients. Throughout the three sub-studies that comprised the overall investigation, particular emphasis was placed on heelstrike and the loading response phase …
