A Unified Risk-Based Framework For Assessing Sustainability And Resiliency Of Civil Infrastructure, Thomas Adam Robbins

Boise State University Theses and Dissertations

As of February 2019, the National Aeronautics and Space Administration (NASA) has reported since 1880 the average global temperature has increased 1°C, with the warmest year on record being 2016. As the years continue to pass, it is becoming more evident that climate change is occurring, which is known to be a catalyst for climatic weather events. Statistically speaking, these events are more prevalent, and catastrophic exemplified as hurricanes, earthquakes, flooding, and fires. In addition to the increase of potentially catastrophic events, society as a whole has become more conscientious in the use and preservation of natural resources, waste generation, …

Seismic Performance Of Earth Slopes Subjected To Earthquake Mainshock – Aftershock Sequences, Alisha Khanal

Civil Engineering Theses

Mainshocks are usually followed by aftershocks. Aftershocks continue over a period of time with a decreasing frequency and there is not sufficient time for repair and retrofit between a mainshock – aftershock sequence. Typically, aftershocks are smaller in magnitude; however, aftershock ground motion characteristics such as the intensity and duration can be greater than the mainshock due to the changes in the earthquake mechanism and location with respect to the site. The seismic performance of slopes is typically evaluated based on the sliding displacement predicted to occur along a critical sliding surface. Various empirical models are available that predict sliding …

Fico® Scores Through The Economic Cycle And Understanding Consumer Sensitivities To Economic Fluctuations, Gerald Fahner

SDSU Data Science Symposium

FICO® Scores assess default likelihood under “normal” conditions. Additional risk emanates from economic variability and manifests itself in changes to the score distribution as well as changes to the Odds-to-Score relationship. In this session we will examine credit bureau data from the Great Recession in the United States as compared to a stable economic period. We’ll share a framework that provides new and actionable insights into consumers’ sensitivities to such economic fluctuations such as:

• Application of counterfactual analysis, machine learning, and scorecards, to rank-order consumers’ sensitivities

• Consumer segmentation by economic sensitivities

• Sensitivity profiling reveals interesting differences between the most and …

Project Insight: A Granular Approach To Enterprise Cybersecurity, Sunna Quazi, Adam Baca, Sam Darsche

SMU Data Science Review

In this paper, we disambiguate risky activity corporate users are propagating with their software in real time by creating an enterprise security visualization solution for system administrators. The current problem in this domain is the lag in cyber intelligence that inhibits preventative security measure execution. This is partially due to the overemphasis of network activity, which is a nonfinite dataset and is difficult to comprehensively ingest with analytics. We address these concerns by elaborating on the beta of a software called "Insight" created by Felix Security. The overall solution leverages endpoint data along with preexisting whitelist/blacklist designations to unambiguously communicate …

Autojack - Hydraulic Powertrain System, Tyce Vu

All Undergraduate Projects

A primary problem for mechanics and automotive enthusiasts is the risk associated with lifting and securing a vehicle with conventional jack stands. Often times, improper jack-stand installation results in the vehicle collapsing unexpectedly, causing injury and/or death. This problem can be minimized through the application of a newly re-designed vehicle lifting system. The conventional method for lifting cars is time consuming and can be unsafe in many circumstances. A better, safer, and more efficient lift design was needed; the AutoJack. The approach of the AutoJack design was entirely focused on the safety of lifting a vehicle. Safety was improved by …

Influence Of Limit Equilibrium Methods In The Design Of Contiguous Cantilever Sheet Pile Walls Through Reliability-Based Analysis, Alvaro J. Mattos, Juan Camilo Viviescas, Juan Pablo Osorio

Conference papers

In geotechnical engineering the design of bored- pile walls is commonly performed in terms of the embedment length (D) defined according to the limit equilibrium methods (also known as balance methods) formulated by Krey, Blum, Rowe, Hansen and the empirical method of Look in sandy soils. The limit equilibrium methods are calculations associated with the shape of the earth pressures distributions in the shaft, earth pressures theories, geotechnical properties and safety factors, while the empirical criteria establish that the relationship between embedment and the free height (H) is of the order of D/H = 1.5. These design methods are complemented …

Capital Efficiency For Development Stage Biotech-Based Firms: An Ipo Perspective, Mark J. Ahn, Amir Shaygan

Engineering and Technology Management Faculty Publications and Presentations

Access to multiple tranches of capital is critical for predominantly no revenue development stage biotech firms. While financing needs are monotonically increasing over multiple years in the product development approval cycle, the market for high risk, milestone driven biotech investment is significantly more volatile than the financial markets as a whole. In this paper, we analyzed the role and relative importance of global biotech IPOs, as well as other sources of capital such as strategic alliances, for research and development funding. We also explored and assessed the degree of mismatch between the access to capital, operational efficiencies, and how firms …

Management Strategy Evaluation: Transdisciplinary And Transparent Natural Resource Management, Eileen Hofmann, Lisa Maddison, Ingrid Van Putten

CCPO Publications

Management Strategy Evaluation (MSE) is a modelling tool used to evaluate sufficiently realistic simulations of potential policy choices in complex systems. As a contribution to the Integrated Marine Biosphere Research (IMBeR) project IMBIZO V, which occurred in October 2017, a workshop was convened with the goal of developing a coherent understanding of best-practice approaches for MSEs. MSEs are becoming standard approaches to characterizing risk across fisheries management organizations globally. MSEs are important tools that aid in delineating objectives, costs, and constraints that define risk and provide a possible mechanism to meet assessment challenges. The MSE workshop considered case studies drawn …

Cataloging The Degree Of Sensitization Via Electrochemical Reactivation For Studying The Corrosion Behavior Of Inconel 718, Austenitic, And Duplex Stainless Steels, Bradley Lynes

Williams Honors College, Honors Research Projects

Corrosion resistant materials can be expensive, but usually reduce the life cycle cost of metallic assets. However, negligent sensitization of these materials can lead to aggressive, intergranular corrosion. Using the methodology of the double loop electrochemical potentiokinetic reactivation (DL-EPR), this project investigates different steel reinforced bars and Inconel to determine the degree of sensitization after a heat treatment of 900°C for 2 hours. The purpose of this research is to validate and determine the appropriate test parameters for performing further DL-EPR test in the future. Additionally, the kinetics observed for each sample during the DL-EPR test will be analyzed and …
