Assessing Land Deformation And Sea Encroachment In The Nile Delta, Egypt, Esayas Gebremichael
Research and Creative Activities Poster Day
Persistent scatterer interferometric analyses were conducted on a stack of 84 Envisat ASAR scenes spanning 7 years (2004 to 2010) over the entire Nile Delta of Egypt and surroundings to monitor the ongoing spatial and temporal land deformation, identify the factors controlling the deformation, and model the interplay between sea level rise and land subsidence to identify areas and populations threatened by sea encroachment by the end of the 21st century. Findings include: (1) general patterns of subsidence in the northern delta, near-steady (none) subsidence in the southern delta, separated by a previously mapped flexure zone undergoing uplift; (2) high ...
Characteristics Of Helicopter Accidents Involving Male And Female Pilots, 2018 Embry-Riddle Aeronautical University - Worldwide
Characteristics Of Helicopter Accidents Involving Male And Female Pilots, Scott S. Burgess, Robert O. Walton, P. Michael Politano
International Journal of Aviation, Aeronautics, and Aerospace
Studies examining aviation accidents have not found differences in accident rates by gender, though there may be gender differences in the types of accident. Baker, Lamb, Grabowski, and Rebok (2001) examined fixed-wing aviation accident rates of male and female private pilots and found that males were more likely to have accidents related to inattention or poor planning while female pilots were more likely to have accidents due to mishandling the aircraft. This research analyzed the National Transportation Safety Board’s aviation accident database system to examine the severity of injury and aircraft damage in rotary-wing (helicopter) accidents by gender. The ...

Communication is instrumental to both the understanding and the management of risks and crises and needs to be systematically examined within these contexts. The Journal of International Crisis and Risk Communication Research is designed to be an outlet for multi-disciplinary inquiry of communication phenomena within a wide range of crises and risks using multiple methods and perspectives.
Subjectivity In Failure Mode Effects Analysis (Fmea) Severity Classification Within A Reliability Centered Maintenance (Rcm) Context, Marc Banghart, Kari Babski-Reeves, Linkan Bian, Lesley Strawderman
International Journal of Aviation, Aeronautics, and Aerospace
This research paper investigated subjectivity in the severity rating of failure modes within a risk analysis process. Although several risk analysis processes can be utilized, the study considered the application of Failure Modes Effects Analysis (FMEA) or Failure Modes Effects and Criticality Analysis (FMECA) due to its common use within the Aerospace Industry. The study investigated both differences in severity selection given varying amounts of experience as well as any association between severity selection and the provided input information. The main goal of the research was to investigate the impact of data quality on severity selection and to identify factors ...
Are Hydraulic Fracturing Fluids Getting Riskier? - An Integrated Approach To Risk Analysis And Data Analytics Using The Fracfocus Database, 2018 University of Colorado at Boulder
Are Hydraulic Fracturing Fluids Getting Riskier? - An Integrated Approach To Risk Analysis And Data Analytics Using The Fracfocus Database, John Forrest Stults
Civil Engineering Graduate Theses & Dissertations
Hydraulic fracturing and horizontal drilling for oil and gas in low-permeability formations has created a boom for the United States energy sector. This rapid increase in oil and gas development in the contiguous United States has put hydraulic fracturing development in direct conflict with development in urban and peri-urban areas. A major concern of hydraulic fracturing proximity to residential development is the potential threat of groundwater contamination due to surface spills. This study addresses the threat of groundwater contamination by developing a risk analysis framework to quantify the groundwater contamination risk posed by 302 chemicals. This framework was then applied ...
Performance Evaluation Of The Children’S Sleepwear Against Hot Water Splash, 2018 Iowa State University
Performance Evaluation Of The Children’S Sleepwear Against Hot Water Splash, Akm Mashud Alam, Yulin Wu, Chunhui Xiang
International Textile and Apparel Association (ITAA) Annual Conference Proceedings
The objective of this research is to examine, for the first time, the hot splash protection provided by the commercially available children’s sleepwear. Three types of commercially available children’s sleepwear, knitted in different fabric structures with different fiber composition, were evaluated. Polyester fabrics, due to better wicking property, spread hot water faster in both horizontal and vertical directions. As a result, a larger body surface area of the wearer would get burnt quickly. Cotton/modacrylic interlock fabrics, due to cotton excellent absorption of water and high thickness of the interlock structure, less body surface area was affected, indicating ...
Probabilistic Regional Landslide Hazard Assessment For The Enguri Dam (Jivari, Georgia), 2018 Michigan Technological University
Probabilistic Regional Landslide Hazard Assessment For The Enguri Dam (Jivari, Georgia), Maria Diletta Acciaro
Dissertations, Master's Theses and Master's Reports
The Enguri Dam forms a reservoir in a seismically active area in the foothills of the Caucasus Mountain range near Jvari, Georgia. The slopes are steep, highly fractured, and weathered, which make them at risk to failure during or following extreme rainfall events. Hydroelectricity produced by the water retained by the 271-m dam provides almost half of the electricity for the country. The reservoir perimeter is more than 40 km and the surrounding slopes span an area of more than 30 km2. The size of the area and paucity of slope data have made slope-failure hazard assessment of the broader ...

Electrical and Computer Engineering Conference Papers, Posters and Presentations
Various methodologies exist for assessing the risk of cascading outage in power systems, differing in the cascading mechanisms considered and in the way they are modeled. These methodologies can be classified in three groups: static computation (QSS methodologies), dynamic computation (dynamic methodologies), or a combination of both (hybrid methodologies). The objective of this paper is to benchmark the performance of several widely used QSS cascading outage methodologies. For that purpose, they are applied on a unique system, the RTS- 96, and the results are compared. Several metrics and indicators are used for that comparison: expected demand loss, distribution of demand ...
Decision Making Under Uncertainty For Design Of Resilient Engineered Systems, 2018 Iowa State University
Decision Making Under Uncertainty For Design Of Resilient Engineered Systems, Cameron A. Mackenzie, Chao Hu
Industrial and Manufacturing Systems Engineering Publications
Designing resilient engineered systems that can sense and withstand adverse events and recover from the effects of the adverse events is increasingly seen as an important goal of engineering design. This paper proposes a value-driven design for resilience (VD2R) framework in order to enable the assessment of system resilience and the optimization of decision variables (or design characteristics) that maximize the value of the system for a firm. The VD2R framework possesses three unique features that allow system resilience and value to be addressed in a theoretically founded and explicit way. First, it assesses the time-dependent resilience of an engineered ...

Innovative Solutions Through Innovated Problems, Shanna R. Daly, Seda Mckilligan, Jaryn A. Studer, Jaclyn K. Murray, Colleen M. Seifert
Industrial Design Publications
Designers are accustomed to solving problems that are provided to them; in fact, common practice in engineering is to present the problem with carefully delineated and detailed constraints required for a promising solution. As a consequence, engineers focus on creating feasible solutions rather than exploring novel perspectives on the presented problems. However, the Engineer of 2020 needs to respond with innovations for multiple and dynamic user needs, diverse users and cultures, and rapidly changing technologies. These complex demands require engineering students to learn that problems are not ‘‘fixed’’ as presented, and to build the habit of exploring alternative perspectives on ...
Modeling Uncertainty In Rooftop Pv Investment Return, 2018 Iowa State University
Modeling Uncertainty In Rooftop Pv Investment Return, Anuj Mittal, Cameron A. Mackenzie, Caroline C. Krejci, Taylor B. Elkins
Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters
Residential energy consumers in the U.S. have shown increased interest in solar-based electricity at home, resulting in increased adoption of photovoltaic (PV) systems on residential rooftops. Empirical research has determined that economic factors are the dominant motivation behind consumers’ decisions to adopt rooftop PV. However, the high degree of uncertainty with respect to return on investment has slowed adoption rates. The factors that drive this uncertainty can be classified as exogenous and endogenous. Exogenous factors include market and environmental factors that are not under the consumers’ control, such as change in net metering policies and future electricity tariffs, and ...
Task Complexity, And Operators’ Capabilities As Predictor Of Human Error: Modeling Framework And An Example Of Application, 2018 Technological University Dublin
Task Complexity, And Operators’ Capabilities As Predictor Of Human Error: Modeling Framework And An Example Of Application, Maria Chiara Leva, Alberto Caimo, R. Duane, Micaela Demichela, Lorenzo Comberti
This paper presents the initial framework adopted to assess human error in assembly tasks at a large manufacturing company in Ireland. The model to characterize and predict human error presented in this paper is linked conceptually to the model introduced by Rasch (1980), where the probability of a specified outcome is modelled as a logistic function of the difference between the person capacity and item difficulty. The model needs to be modified to take into account an outcome that is not dichotomous and feed into the interaction between two macro factors: (a) Task complexity: that sum-marises all factors contributing to ...

Application Of Real Field Connected Vehicle Data For Aggressive Driving Identification On Horizontal Curves, 2017 San Diego State University
Application Of Real Field Connected Vehicle Data For Aggressive Driving Identification On Horizontal Curves, Arash Jahangiri, Vincent Berardi, Sahar Ghanipoor Machiani
Psychology Faculty Articles and Research
The emerging technology of connected vehicles generates a vast amount of data that could be used to enhance roadway safety. In this paper, we focused on safety applications of a real field connected vehicle data on a horizontal curve. The database contains connected vehicle data that were collected on public roads in Ann Arbor, Michigan with instrumented vehicles. Horizontal curve negotiations are associated with a great number of accidents, which are mainly attributed to driving errors. Aggressive/risky driving is a contributing factor to the high rate of crashes on horizontal curves. Using basic safety message data in connected vehicle ...
Implementing The Heston Option Pricing Model In Object-Oriented Cython, 2017 Utah State University
Implementing The Heston Option Pricing Model In Object-Oriented Cython, Brandon Hardin
All Graduate Plan B and other Reports
The 1973 Black-Scholes model, a revolutionary option pricing formula whose price is 'relatively close to observed prices, makes an assumption that the volatility is constant and thus, deterministic. This causes some inefficiencies and patterns in the pricing of options due to the model providing evidence of the volatility smile' of the volatility. Many scholars have suggested that the volatility should be modelled by a stochastic process and the (1993) Heston Model is one of many proposed solutions to remedy this problem. The Heston Model allows for the 'smile' by defining the volatility as a stochastic process. This thesis considers a ...
Reliability-Based Designs Procedure Of Earth Retaining Walls In Geotechnical Engineering, 2017 Universidad de Antioquia
Reliability-Based Designs Procedure Of Earth Retaining Walls In Geotechnical Engineering, Juan Camilo Viviescas, Juan Pablo Osorio, Julio E. Canon
The design and construction of foundations, retaining structures and slopes are usually based on deterministic formulations that do not allow the distinction between the natural variability and the inherent dispersion in the geotechnical parameters. Due to the inherent variability of the soil properties, there is a growing trend to implement reliability-based designs in geotechnical engineering to reduce design uncertainties by probabilistic methods. The reliability designs require the definition of the probability density functions of the geotechnical properties, as well as knowledge of the spatial variability of soils. This paper identifies the procedures, type of soil investigations, simulations and the most ...
Airport Security Investment Model, 2017 University of Arkansas, Fayetteville
Airport Security Investment Model, Joshua Daniel Bolton
Theses and Dissertations
In an increasingly mobile and diverse world, it is difficult to quantify the risk, or danger, associated with traveling. Airports have suffered greatly for being unable to define potential risks and protect against them. Intelligent adversary risk is a complicated high-level issue for many airports. Airports are targeted because of the large amount of people in a confined space and the social, economic, and psychological impact of terrorist attacks on the American people. In the months following September 11th, 2001, the airline industry in the United States lost $1.1 billion in revenue. The American people stayed grounded, for fear ...
High Consequence Scenarios For North Korean Atmospheric Nuclear Tests With Policy Recommendations For The U.S. Government, 2017 James Madison University
High Consequence Scenarios For North Korean Atmospheric Nuclear Tests With Policy Recommendations For The U.S. Government, Thomas S. Popik, Jordan T. Kearns, George H. Baker Iii, Henry F. Cooper, William R. Harris
Department of Integrated Science and Technology - Faculty Scholarship
The government of North Korea has declared high-altitude EMP-capability to be a “strategic goal” and has also threatened an atmospheric test of a hydrogen bomb. Atmospheric nuclear tests have the potential to cripple satellites and the undersea cable networks critical to communication, and navigation necessary for trans-Pacific trade among the U.S., China, and other nations. When a nuclear warhead is detonated at high altitude, a series of electromagnetic pulses radiate downward within the line of sight of the blast. These pulses can disable equipment with miniature electronics and long conductors. Electric grid controls and transmission systems are especially vulnerable ...

Benchmarking Estonia's Cyber Security: An On-Ramping Methodology For Rapid Adoption And Implementation, Ernest Wong, Nan Porter, Mckinnon Hokanson, Bing Bing Xie
In April of 2007, Estonia fell victim to a series of distributed denial of service (DDoS) attacks that crippled its government websites, email servers, media outlets, and banking system for nearly a month. Due to the devastating effects of these cyber attacks, Estonia took great efforts to strengthen its cyber security protocols. This research analyzes the reforms that Estonia has implemented in its domestic and foreign policies and attempts to determine if any of it systemic improvements can help to also bolster cyber security in the United States (US). The findings from this research are that Estonia’s policy reforms ...
