Optimum Injury And Illness Prevention Cost For U.S. Construction Projects, Sathyanarayanan Rajendran, Morgan Bliss, Dominic Klyve Jun 2017

Optimum Injury And Illness Prevention Cost For U.S. Construction Projects, Sathyanarayanan Rajendran, Morgan Bliss, Dominic Klyve

Mathematics Faculty Scholarship

Worker injuries and illnesses can affect the profitability of an organization. Regardless of the regulatory requirements for safety and health, many organizations prefer to see positive returns (i.e., better safety metric performance) on their safety investments (i.e., project costs associated with injury and illness prevention programs). Understanding the relationship between costs associated with an injury and illness prevention program of a construction project and project safety performance is critical to the future success of construction organizations in the United States. In evaluating this relationship, the authors’ goal was to identify an equilibrium point of injury and illness prevention program investment …


Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, Armando Jacob Espinoza, Thomas Conner Field Jun 2017

Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, Armando Jacob Espinoza, Thomas Conner Field

Materials Engineering

This presentation contains an assessment of the best overall corrosion monitoring device, intrusive or non-intrusive, for use in the petrochemical industry. Corrosion in the petrochemical industry is a large issue because it causes a deterioration of pipe integrity in fuel processing systems. A reduction of pipe wall integrity due to corrosion could result in a leak or an explosion of fuel processing lines since those systems function at high pressures. The use of corrosion monitoring systems in the petrochemical industry helps to detect early signs of corrosion prior to failure so that proper maintenance can be performed to prevent catastrophe. …


Motion Dynamics Of Dropped Cylindrical Objects, Gong Xiang May 2017

Motion Dynamics Of Dropped Cylindrical Objects, Gong Xiang

LSU New Orleans Theses and Dissertations

Dropped objects are among the top ten causes of fatalities and serious injuries in the oil and gas industry. Objects may be dropped during lifting or any other offshore operation. Concerns of health, safety, and the environment (HSE) as well as possible damages to structures require the prediction of where and how a dropped object moves underwater. This study of dropped objects is subdivided into three parts. In the first part, the experimental and simulated results published by Aanesland (1987) have been successfully reproduced and validated based on a two-dimensional (2D) theory for a dropped drilling pipe model. A new …

Who R U? Identity Theft And Unl Students, Marcia L. Dority Baker, Cheryl O'Dell

Information Technology Services: Publications

How can academic institutions help educate their students about the risks of identity theft? Or teach students to better understand how one’s online presence can hold so much joy and angst? For one campus, the University of Nebraska–Lincoln, the opportunity came from a middle school teacher engaging his students in a future problem-solving activity. UNL had the opportunity to create a 45-minute presentation on identity theft for local public school students who would be spending the day on campus researching this topic.

While preparing the presentation, we realized a top 10 list on identity theft for UNL students would be …


Cost Versus Risk: The Policy Of Nuclear Weapon Maintenance Of Tritium Based Limited Life Components, Michael P. Mason Mar 2017

Cost Versus Risk: The Policy Of Nuclear Weapon Maintenance Of Tritium Based Limited Life Components, Michael P. Mason

Theses and Dissertations

This research develops a method to measure the cost to society of current maintenance policy for the exchange of tritium based limited life components within nuclear weapons. The incentives for the Department of Energy and Department of Defense which causes either a substantial cost or substantial risk to be accepted by either Department. A simulation model is created to measure the current policy and compare it to different policies in order to recommend a policy that would minimize the cost to society. The measurement of the cost to society will offer decision makers insight into the ramifications of their decisions.


Risk Optimized Microgrid Resource Management, Thomas William Cashel Iii Jan 2017

Risk Optimized Microgrid Resource Management, Thomas William Cashel Iii

Electronic Theses and Dissertations

This thesis proposes a risk based price adjustment method for a day ahead scheduling of a distribution side tiered community microgrid within a transactive energy style market. The system is organized into a master controller and local controller confïguration to simulate behind meter activity that is not visible to the master controller. Conditional value at risk is used to asses the risk of distributed energy resources in each local controller and the risk for each local controller is aggregated providing each local controller a single risk value. Each device's, or local controller's, risk value is used to adjust the price …


Built-In Bicycle Rack For Cars, Scott A. Hansberry Jan 2017

Built-In Bicycle Rack For Cars, Scott A. Hansberry

All Undergraduate Projects

Transporting a bicycle after riding somewhere and then needing to be pickup can be problematic. Bicycles will not fit in most vehicles without removing components. There is also the risk of damaging the inside of the vehicle. Expecting everyone to have a bike rack for their vehicle is unrealistic because the bike rack could be considered unappealing visually, take up to much space in the trunk, or limit the vehicle owner’s access to the trunk. The solution to this problem is a bike rack that mounts onto your car and then mounts your bike onto the rack. Most people don’t …


The Impact Of Requirements Management Documentation On Software Project Outcomes In Health Care, Sujatha Alla, Pilar Pazos, Rolando Delaguila Jan 2017

The Impact Of Requirements Management Documentation On Software Project Outcomes In Health Care, Sujatha Alla, Pilar Pazos, Rolando Delaguila

Engineering Management & Systems Engineering Faculty Publications

Despite considerable time and resources spent on the initiation phase of software projects, discrepancies often exist between formal project documentation, customer requirements, and final project specifications. Such discrepancies in the requirements management process can have a very negative impact on final project outcomes. The Business Requirements Document (BRD) constitutes the formal software requirements documentation, which typically includes stakeholders’ needs and expectations and project scope while providing a clear project roadmap and project plan. According to IEEE standards, a BRD should be a structured document that includes specific elements such as functional and technical requirements while incorporating certain traits such as …


Resilience In Ecotoxicology: Toward A Multiple Equilibrium Concept, Mirco Bundschuh, Ralf Schulz, Ralf B. Schäfer, Craig R. Allen, David G. Angeler Jan 2017

Resilience In Ecotoxicology: Toward A Multiple Equilibrium Concept, Mirco Bundschuh, Ralf Schulz, Ralf B. Schäfer, Craig R. Allen, David G. Angeler

School of Natural Resources: Faculty Publications

The term resilience describes stress-response patterns across scientific disciplines. In ecology, advances have been made to clearly define resilience based on underlying mechanistic assumptions. Engineering resilience (rebound) is used to describe the ability of organisms to recover from adverse conditions (disturbances), which is termed the rate of recovery. By contrast, the ecological resilience definition considers a systemic change, that is, when ecosystems reorganize into a new regime following disturbance. Under this new regime, structural and functional aspects change considerably relative to the previous regime, without recovery. In this context, resilience is an emergent property of complex systems. In the present …


Nuclear Power: Black Sky Liability Or Black Sky Asset?, Sherrell R. Greene Dec 2016

Nuclear Power: Black Sky Liability Or Black Sky Asset?, Sherrell R. Greene

International Journal of Nuclear Security

Ready access to abundant electricity is a key enabler of modern life. During the past decade the vulnerability of Critical Infrastructure sectors in the U.S. to a variety of natural hazards and man-made threats has become increasingly apparent. The electrical infrastructure (the “Grid”) is the foundation for all other critical civil infrastructures upon which our society depends. Therefore, protection of the Grid is an energy security, homeland security, and national security issue of highest importance. Geomagnetic disturbances (GMD) induced by solar coronal mass ejections (CMEs), electromagnetic pulse (EMP) attacks, and cyber attacks are three events having the potential to plunge …

A Traders Guide To The Predictive Universe- A Model For Predicting Oil Price Targets And Trading On Them, Jimmie Harold Lenz Dec 2016

A Traders Guide To The Predictive Universe- A Model For Predicting Oil Price Targets And Trading On Them, Jimmie Harold Lenz

Doctor of Business Administration Dissertations

At heart every trader loves volatility; this is where return on investment comes from, this is what drives the proverbial “positive alpha.” As a trader, understanding the probabilities related to the volatility of prices is key, however if you could also predict future prices with reliability the world would be your oyster. To this end, I have achieved three goals with this dissertation, to develop a model to predict future short term prices (direction and magnitude), to effectively test this by generating consistent profits utilizing a trading model developed for this purpose, and to write a paper that anyone with …

Towards A Development Of A Mobile Application Security Invasiveness Index, Sam Espana Oct 2016

Towards A Development Of A Mobile Application Security Invasiveness Index, Sam Espana

KSU Proceedings on Cybersecurity Education, Research and Practice

The economic impact of Mobile IP, the standard that allows IP sessions to be maintained even when switching between different cellular towers or networks, has been staggering in terms of both scale and acceleration (Doherty, 2016). As voice communications transition to all-digital, all-IP networks such as 4G, there will be an increase in risk due to vulnerabilities, malware, and hacks that exist for PC-based systems and applications (Harwood, 2011). According to Gostev (2006), in June, 2004, a well-known Spanish virus collector known as VirusBuster, emailed the first known mobile phone virus to Kaspersky Lab, Moscow. Targeting the Symbian OS, the …


Guidance Index For Shallow Landslide Hazard Analysis, Cheila Cullen Sep 2016

Guidance Index For Shallow Landslide Hazard Analysis, Cheila Cullen

Dissertations, Theses, and Capstone Projects

Rainfall-induced landslides are one of the most frequent hazards on slanted terrains. They lead to considerable economic losses and fatalities worldwide. Intense storms with high-intensity and long-duration rainfall have high potential to trigger rapidly moving soil masses due to changes in pore water pressure and seepage forces. Nevertheless, regardless of the intensity-duration of the rainfall, shallow landslides are influenced by antecedent soil moisture conditions. To the present day, no system exists that dynamically interrelates these two factors.

This work establishes a relationship between antecedent soil moisture and rainfall expressed in the form of a Shallow Landslide Index (SLI) at 1km …


Air Force Project Risk Management – The Impact Of Inconsistent Processes, Eric J. Perez Sep 2016

Air Force Project Risk Management – The Impact Of Inconsistent Processes, Eric J. Perez

Theses and Dissertations

On the surface, the majority of Air Force units appear to be executing some form of project risk management (PRM). Deeper investigation exposes many of the PRM practices currently in place to often be ad hoc, and as such, have the potential to poorly inform decisions when risk data is escalated to the enterprise levels of the Air Force. Resultantly, there is inconsistency between the PRM processes practiced by Air Force units. This inconsistency is an indication of risk mishandling at the project level and erroneous risk data provided at the enterprise levels of the Air Force. It may be …

Toward Risk Assessment 2.0: Safety Supervisory Control And Model-Based Hazard Monitoring For Risk-Informed Safety Interventions, Francesca Favaro, Joseph Saleh Aug 2016

Toward Risk Assessment 2.0: Safety Supervisory Control And Model-Based Hazard Monitoring For Risk-Informed Safety Interventions, Francesca Favaro, Joseph Saleh

Faculty Publications

Probabilistic Risk Assessment (PRA) is a staple in the engineering risk community, and it has become to some extent synonymous with the entire quantitative risk assessment undertaking. Limitations of PRA continue to occupy researchers, and workarounds are often proposed. After a brief review of this literature, we propose to address some of PRA׳s limitations by developing a novel framework and analytical tools for model-based system safety, or safety supervisory control, to guide safety interventions and support a dynamic approach to risk assessment and accident prevention. Our work shifts the emphasis from the pervading probabilistic mindset in risk assessment toward the …


Incorporating A New Class Of Uncertainty In Disaster Relief Logistics Planning, Emre Kirac Aug 2016

Incorporating A New Class Of Uncertainty In Disaster Relief Logistics Planning, Emre Kirac

Graduate Theses and Dissertations

In recent years, there has been a growing interest among emergency managers in using Social data in disaster response planning. However, the trustworthiness and reliability of posted information are two of the most significant concerns, because much of the user-generated data is initially not verified. Therefore, a key tradeoff exists for emergency managers when considering whether to incorporate Social data in disaster planning efforts. By considering Social data, a larger number of needs can be identified in a shorter amount of time, potentially enabling a faster response and satisfying a class of demand that might not otherwise be discovered. However, …


A Model Of Human Harm From A Falling Unmanned Aircraft: Implications For Uas Regulation, Andrew V. Shelley Jul 2016

A Model Of Human Harm From A Falling Unmanned Aircraft: Implications For Uas Regulation, Andrew V. Shelley

International Journal of Aviation, Aeronautics, and Aerospace

This paper quantifies the human harm, in the form of fatalities and skull fractures, which could occur as a result of an unmanned aircraft falling from a height. The analysis is used to establish the maximum height at which an unmanned aircraft can be flown over people to achieve a level of safety consistent with the rate of ground fatalities from General Aviation. The maximum height is dependent on the aircraft mass and the population density of people on the ground below.

The results are used to inform a critical evaluation of recent recommendations from the FAA-chartered “Unmanned Aircraft Systems …
