Volcano Infrasound Monitoring With Applications For Statistical Forecasting Of Explosions At Sakurajima (Japan), Matthew R. Vonlintig

Boise State University Theses and Dissertations

Volcanic eruptions are powerful natural phenomena that often occur unpredictably in time and magnitude. Nearby communities are put at risk during volcanic unrest; however, when hazards are well understood and clearly defined risk can be mitigated. This thesis addresses the problem of forecasting the likelihood of future explosive volcanic behavior by monitoring ongoing eruptive history with infrasound. I parameterize inter-event temporal behavior to determine the eruption controlling processes is material failure opposed to changes in magma and volatile supply.

I analyze data from Sakurajima, a type-example open volcano, using two local (4 km from the vent) microphone arrays, which recorded …

A Secure Computing Platform For Building Automation Using Microkernel-Based Operating Systems, Xiaolong Wang

USF Tampa Graduate Theses and Dissertations

Building Automation System (BAS) is a complex distributed control system that is widely deployed in commercial, residential, industrial buildings for monitoring and controlling mechanical/electrical equipment. Through increasing industrial and technological advances, the control components of BAS are becoming increasingly interconnected. Along with potential benefits, integration also introduces new attack vectors, which tremendous increases safety and security risks in the control system. Historically, BAS lacks security design and relies on physical isolation and "security through obscurity". These methods are unacceptable with the "smart building" technologies. The industry needs to reevaluate the safety and security of the current building automation system, and …

The Nebraska Mesonet: Technical Overview Of An Automated State Weather Network, Martha Shulski, Stonie Cooper, Glen Roebke, Allen L. Dutcher

School of Natural Resources: Faculty Publications

The Nebraska Mesonet was established in 1981 as one of the nation’s first automated state weather networks. ‘‘Automated’’ is defined by the nature of the observations being made and recorded by machine, as opposed to observations made and recorded manually. At the time of inception, the five observing locations were geared toward servicing agricultural production applications. The Nebraska Mesonet has grown to 69 stations (as of 2018) and is now a multipurpose environmental observing network under the Nebraska State Climate Office (NSCO). The network is composed of environmental observation stations, sited using best practices for mesoscale and microscale environment situations. …

Statistical Investigation Of Road And Railway Hazardous Materials Transportation Safety, Amirfarrokh Iranitalab

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Transportation of hazardous materials (hazmat) in the United States (U.S.) constituted 22.8% of the total tonnage transported in 2012 with an estimated value of more than 2.3 billion dollars. As such, hazmat transportation is a significant economic activity in the U.S. However, hazmat transportation exposes people and environment to the infrequent but potentially severe consequences of incidents resulting in hazmat release. Trucks and trains carried 63.7% of the hazmat in the U.S. in 2012 and are the major foci of this dissertation. The main research objectives were 1) identification and quantification of the effects of different factors on occurrence and …

Comparison Of Modeled And Measured Pesticide Concentrations In Air, Trenell Davis Boggans

USF Tampa Graduate Theses and Dissertations

Chlorpyrifos (CPF) is a popular organophosphorus insecticide that is heavily used in the agriculture industry as a means of pest control. Chlorpyrifos is known for its toxic effect to inhibit the enzyme acetylcholinesterase (ACHE) in humans and is widely used in areas of California where the site of application is close to occupied areas, such that exposures to residents and bystanders can occur due to secondary drift. Secondary drift refers to the volatilization of a pesticide from the surface to which it was applied (e.g. soil or plant foliage) and subsequent off-site movement in ambient air. Secondary drift is different …

The Role Of Ground-Source Heat Pumps In Achieving New Jersey’S 80% By 2050 Goal: Addressing Emissions From The Buildings Sector, Sheryl Tembe

Sustainability Seminar Series

Emissions reduction and renewable energy sources are vital to health of New Jersey. Governor Murphy’s executive orders and recent legislation target actions to improve our environment and create a sustainable future. The buildings sector is recognized as the second largest source of greenhouse gas emissions in New Jersey behind transportation, with the majority of emissions due to fossil fuel-based heating and cooling. To reach state’s goal of 80% emissions reduction by 2050, reduction strategies for the built environment must implement technologies that displace fossil fuels and maximize clean and low-carbon electricity. Heat pumps are a key technology because of their …

Cross-Referencing Social Media And Public Surveillance Camera Data For Disaster Response, Chittayong Surakitbanharn,, Calvin Yau, Guizhen Wang, Aniesh Chawla, Yinuo Pan, Zhaoya Sun, Sam Yellin, David Ebert, Yung-Hsiang Lu, George K. Thiruvathukal

Computer Science: Faculty Publications and Other Works

Physical media (like surveillance cameras) and social media (like Instagram and Twitter) may both be useful in attaining on-the-ground information during an emergency or disaster situation. However, the intersection and reliability of both surveillance cameras and social media during a natural disaster are not fully understood. To address this gap, we tested whether social media is of utility when physical surveillance cameras went off-line during Hurricane Irma in 2017. Specifically, we collected and compared geo-tagged Instagram and Twitter posts in the state of Florida during times and in areas where public surveillance cameras went off-line. We report social media content …

Waterfall Formation At A Desert River-Reservoir Delta Isolates Endangered Fishes, Charles N. Cathcart, Casey A. Pennock, Christopher A. Cheek, Mark C. Mckinstry, Peter D. Mackinnon, Mary M. Conner, Keith B. Gido

Wildland Resources Faculty Publications

Unforeseen interactions of dams and declining water availability have formed new obstacles to recovering endemic and endangered big-river fishes. During a recent trend of drying climate and declining reservoir water levels in the southwestern United States, a large waterfall has formed on two separate occasions (1989-1995 & 2001-present) in the transition zone between the San Juan River and Lake Powell reservoir because of deposited sediments. Because recovery plans for two large-bodied endangered fish species, razorback sucker (Xyrauchen texanus) and Colorado pikeminnow (Ptychocheilus lucius), include annual stockings in the San Juan River, this waterfall potentially blocks upstream …

Resonance Attacks On Load Frequency Control Of Smart Grids, Yongdong Wu, Zhuo Wei, Jian Weng, Xin Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

Load frequency control (LFC) is widely employed to regulate power plants in modern power generation systems of smart grids. This paper presents a simple and yet powerful type of attacks, referred to as resonance attacks, on LFC power generation systems. Specifically, in a resonance attack, an adversary craftily modifies the input of a power plant according to a resonance source (e.g., rate of change of frequency) to produce a feedback on LFC power generation system, such that the state of the power plant quickly becomes instable. Extensive computer simulations on popular LFC power generation system models which consist of linear, …

Environmental Conditions In San Martin Lake: Effects Of Eutrophication In An Estuary Associated With The Laguna Madre, Wendy L. Rogers

Theses and Dissertations

San Martin Lake is a shallow water Estuary in the lower Laguna Madre off the Port of Brownsville Shipping channel. It is influenced both by incoming tides and waste water runoff both from local farms and the Brownsville water treatment plants. The resulting mixture of eutrophic water and incoming sea water creates the perfect mix for a potential algal bloom. This study looks at the nutrient levels and environmental conditions in the main basin of the estuary to establish baseline levels and to observe the rate of nutrient clearing being accomplished in this environment. As sport recreation in the area …

The Perception Of Utah Division Of Wildlife Resource’S Law Enforcement By Local, County And Municipal Law Enforcement Agencies, Wyatt Bubak

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Like most states throughout the nation, Utah’s population has continually grown since settlement. In 2014 Utah’s population was estimated at 2.95 million and between 2015-2016 Utah had the highest percentage growth rate of any state in the nation. This profound amount of growth can be attributed to many factors that are unique to Utah; two of which are the aesthetic and recreational opportunities available to Utah residents.

Due to population growth and urban sprawl, areas commonly patrolled by Utah Division of Wildlife Resources (UDWR) conservation officers are now located closer to urban populations. Previously rural or backcountry areas are seeing …

Hydrodynamic Drivers Of Dissolved Oxygen Variability Within A Highly Developed Tidal Creek In Myrtle Beach, South Carolina, Douglas Matthew Pastore

Electronic Theses and Dissertations

Erosion and water quality degradation have been observed in Singleton Swash in Myrtle Beach, SC, and have been hypothesized to be related to migration of the beach-face channel. Dredging this channel temporarily fixes erosional threats to nearby infrastructure but the effects on water quality are not well understood. It is hypothesized that variations in dissolved oxygen (DO) concentration (used here as a proxy for water quality) within the water column are related to changes in vertical mixing and transport due to oceanic tidal forcing. This study utilizes current meters, pressure sensors, and optical DO probes to measure and study the …

Even though many different types of data are being generated and analyzed in various domains, the development of distributed city-level cyberinfrastructure …

Moving Target Defense For Securing Scada Communications, Vahid Heydari

College of Science & Mathematics Departmental Research

In this paper, we introduce a framework for building a secure and private peer to peer communication used in supervisory control and data acquisition networks with a novel Mobile IPv6-based moving target defense strategy. Our approach aids in combating remote cyber-attacks against peer hosts by thwarting any potential attacks at their reconnaissance stage. The IP address of each host is randomly changed at a certain interval creating a moving target to make it difficult for an attacker to find the host. At the same time, the peer host is updated through the use of the binding update procedure (standard Mobile …

Faculty Publications

National data indicate that initial mathematics course placement in college is a strong predictor of persistence to degree in engineering, with students placed in calculus persisting at nearly twice the rate of those placed below calculus. Within the state of South Carolina, approximately 95% of engineering-intending students who initially place below calculus are from in-state. In order to make systemic change, we are first analyzing system-wide data to identify prevalent educational pathways within the state, and the mathematical milestones along those pathways taken by students in engineering and engineering-related fields. This paper reports preliminary analysis of that data to understand …

Reserved Optimisation: Handling Incident Priorities In Emergency Response Systems, Muralidhar Konda, Supriyo Ghosh, Pradeep Varakantham

Research Collection School Of Computing and Information Systems

Emergency (medical, fire or criminal) Management Systems(EMSs) are crucial for ensuring public safety and security. Typically in many cities, less than 20% of the cases received by EMSs belong to the extremely serious category and require immediate help. Rest of the incidents typically are less serious and thereby allow more flexibility in response time. Therefore, for efficient management of EMS requests, several EMSs now categorise an incoming emergency request into apriority level based on well studied “triaging” methods. Leading research on optimising emergency response has either focussed on data-driven models for settings with homogenous incidents or on generic heuristics (that …

Making And Breaking Trust In Forest Collaborative Groups, Emily Jane Davis, Lee K. Cerveny, Donald R. Ulrich, Meagan L. Nuss

Humboldt Journal of Social Relations

There has been a recent increase in use of an organized, forest ‘collaborative’ group approach for multi-stakeholder input on federal forestlands in the U.S. West. This approach relies on the creation of shared trust to achieve social agreement. Yet growing critiques suggest a lack of trust in the U.S. Forest Service [Forest Service], between stakeholders, and the collaborative process itself. We conducted three comparative case studies of established forest collaborative groups in Oregon, Washington, and Idaho to ask how trust is created and damaged or broken in this context. We found multiple, interlinked dimensions to trust, including significant reliance on …

Who’S In Charge? The Role Of Power In Collaborative Governance And Forest Management., Patricia B. Orth, Antony S. Cheng

Humboldt Journal of Social Relations

Collaborative processes for working toward common management goals between individuals and organizations, despite their differences, emerged as one enduring legacy resulting from the Timber Wars in the American West during the late-1980s and the early 1990s. Power imbalances are often cited as a common problem in collaborative processes and can have a lasting, deleterious impact on the collaborative process and its outcomes. For all its importance, however, there is a yet unfulfilled need to understand the extent to which power and power imbalances affect collaborative relationships. Our research uses a case study approach to qualitatively analyze power dynamics within three …

Addressing The Regulator's Dilemma: A Self Drive Framework For Balancing Safety And Innovation, Craig Maughan

Brigham Young University Prelaw Review

Policymakers are tasked with creating regulations that responsibly oversee the growth and deployment of emerging technologies. I argue that the SELF DRIVE Act, currently being deliberated in Congress, offers one such intelligent regulatory structure for autonomous vehicles: it prioritizes public safety over adherence to outdated requirements, giving innovators greater freedom to field-test new designs. More importantly, I examine how key principles of the SELF DRIVE Act should be applied to other emerging technologies currently facing regulatory roadblock. Specifically, I suggest the drone industry be subject to regulatory changes that incentivize safety, allow exploration, and anticipate future growth. Such regulations allow …

The Impact Of Past Experience With Tornadoes On Future Decisions, Emily Paltz, Michael Hayes

Honors Program: Senior Projects (Public)

Tornadoes are a dangerous threat to public safety. The National Weather Service (NWS), therefore, advises the public to go to an interior room on the lowest level of their houses when a tornado warning is issued for their area. As the NWS Central Region Service Assessment of the Joplin, Missouri Tornado published in July 2011 reveals, however, this is often not the first action taken after learning that there is danger of being hit by a tornado. Rather, people need to seek confirmation from more than one source before following the recommended action. The goal of this research project is …
