Cyber-Physical Systems: Complex System Governance As An Integrating Construct, Polinpapilinho F. Katina, Charles B. Keating, Adrian V. Gheorghe
Engineering Management & Systems Engineering Faculty Publications
This paper examines contributions of Complex System Governance (CSG) as an integrating construct for the emerging fields of critical cyber-physical systems (CPS). CPS is concerned with physical entities that are controlled by computational elements. The field is relatively new, emerging, and also somewhat fragmented in development. There are multiple agencies, entities, and activities being undertaken to address a nexus of emerging issues (e.g., cybersecurity) in critical infrastructures. However, the development of critical CPS, as a field, albeit with good intentions and efforts, appears to be largely ‘self-organizing.’ In response, we suggest CSG as an organizing construct capable of provided a …
Using Mavt To Incorporate Public Perception When Choosing A Nuclear Fuel Cycle, Stephen Clement
Using Mavt To Incorporate Public Perception When Choosing A Nuclear Fuel Cycle, Stephen Clement
Theses and Dissertations
Nuclear energy is a source of carbon free power. With many countries striving to make deep carbon cuts in their energy sectors, nuclear energy could be a large part of the solution. One of the main obstacles standing in the way of the use of nuclear energy is the issue of used nuclear fuel disposal. According to the NEI, the U.S. creates about 2000 metric tons of used nuclear fuel per year and has generated around 76,000 metric tons of used nuclear fuel over the last 4 decades. While there are technical problems that need to be solved, it is …

The Next Billion: Lessons In Off-Grid Electricity Development From The Global South, Peter Mcdonough
Graduate Student Theses, Dissertations, & Professional Papers
Today about a third of the world’s population has no access to electricity, and another third has only limited access. Driven by the push for development on one hand and the reality of climate change on the other, a combination of for-profit companies, NGOs, missions, and aid organizations is looking for the silver bullet to sustainable electricity development. In order to understand the challenges facing off-grid electricity projects I used recent literature in the form of peer-reviewed journals, agency reports, news articles, and technical documents; stakeholder interviews; and on-site observations in selected case studies in Nepal, India, and Tanzania. In …

Laboratory Exercise- Mapping The Risk Of Structural Failure In Schools Due To An Earthquake, Joel Barker, Kimberly Sowards, Casey Webb
Engineering Applications of GIS - Laboratory Exercises
Utah’s present geology has been greatly dictated by tectonic stresses that have occurred over the last 0.7 Ga. A determining factor in much of this Geology is the Hingeline that runs through Salt Lake County. Throughout the history of the western North America, this has been an important weak zone. It is no surprise that this same zone is now home to the Wasatch Fault System, which accommodates some of the extension of Western North America. The steep mountains facing west toward Salt Lake City were formed from the tectonic processes of the Fault. The Wasatch Fault is a normal …

Laboratory Exercise – Ideal Locations For A Family, Benjamin Barrett, Colin Esplin, Chris Garcia
Engineering Applications of GIS - Laboratory Exercises
Upon the successful completion of a college degree, many students (and their families) are offered job positions in various locations throughout the Unites States. As a result, these young families are tasked with the challenge of finding a suitable place to live in an area they are completely unfamiliar with. By using a model in ArcMap this task can be made much easier. In this lab a model will be created in ArcGIS Model Builder along with a corresponding map showing suitable locations.

Laboratory Exercise – Determining Evacuation Route For Deer Creek Dam Failure, Eleise Hinton, Matt Randall, Brian Packer
Engineering Applications of GIS - Laboratory Exercises
Deer Creek Reservoir holds a volume of approximately 153,000 acre-ft of water. All of this water is held back by Deer Creek dam. Below the dam, the Provo River flows through Provo Canyon and down into Provo before terminating at Utah Lake. While the chance of a dam break is considered unlikely, an extreme event such as a major earthquake could trigger a break. In the case of a dam break, residents of Provo who live in the flood path will need to know where to evacuate. This exercise will create a model to show the nearest evacuation sites for …

Some major factors in deciding where one’s family should live include relative safety of the neighborhood, available green space such as parks and schools, grocery stores, and other commercial retail in the area. With the legalization of marijuana in states such as Colorado, proximity of these marijuana dispensaries has become another factor. The Normalized Difference Vegetation Index (NDVI) can be used as a measure of vegetation, and to determine areas with high levels of irrigated vegetation. Using ArcGIS Modelbuilder, the data from an NDVI analysis can be used to determine the proximity of marijuana shops to these types of greenspaces …

The Use Of Remote Sensing Technologies And Models To Study Pollutants In Pdn Region, Suhail Mahmud
Open Access Theses & Dissertations
Using a suite of modeling techniques and instrumentation we study the atmospheric pollutants in the PdN Region. The first objective of this work was to measure hemi-spherically integrated, spectrally resolved solar photon flux (actinic flux) between the wavelengths 300 and 700 nm, and use the measured actinic flux to improve air quality simulations. Actinic flux was measured in the PdN region in order to calculate photolysis rate coefficients for different pollutants. The improved photolysis rate coefficients were then integrated into a photochemical air quality model (CAMx) in order to improve air quality forecasting. We present the simulations performed for a …

Environmental Dynamics: A Compendium Of Rhetorical Application, Annalisa Perez
Open Access Theses & Dissertations
Technology, albeit exceedingly useful, has exponentially exacerbated the communications dilemma between the technical and the non-technical. Additionally, based on a current new understanding of the term environmental, it can no longer be fully defined by terms such as air, water, waste, or purification. Rather, the meaning of environmental has been globally transformed in several ways. The term environmental is encompassing an expansion of understanding and is further defined with words such as essence, perception, rapport and multi-dimensional spaces. This work, Environmental Dynamics: A Compendium of Rhetorical Application (EDC), provides a framework where communication can be enhanced in areas where communication …

Managing Risks Of Market Price Uncertainty For A Microgrid Operation, Sriram Raghavan
Managing Risks Of Market Price Uncertainty For A Microgrid Operation, Sriram Raghavan
Masters Theses
"After deregulation of electricity in the United States, the day-ahead and real-time markets allow load serving entities and generation companies to bid and purchase/sell energy under the supervision of the independent system operator (ISO). The electricity market prices are inherently uncertain, and can be highly volatile. The main objective of this thesis is to hedge against the risk from the uncertainty of the market prices when purchasing/selling energy from/to the market. The energy manager can also schedule distributed generators (DGs) and storage of the microgrid to meet the demand, in addition to energy transactions from the market. The risk measure …

A Cracking Methodology To Assess Fracture And Fatigue Properties Of Asphalt Concrete Mixtures Using Overlay Tester, Victor M. Garcia
A Cracking Methodology To Assess Fracture And Fatigue Properties Of Asphalt Concrete Mixtures Using Overlay Tester, Victor M. Garcia
Open Access Theses & Dissertations
Several highway agencies have either implemented or considered implementing performance tests to predict the cracking potential of asphalt concrete (AC) mixtures in the laboratory setting. One such test, the Overlay Tester (OT) test, measures the number of cycles to failure of the AC specimens by simulating the opening and closing of the cracks induced by daily temperature variations and high tensile strain generated by the traffic load. The variability of the OT test results is expressed as a major concern in reliably characterizing the cracking potential of the AC mixes.
The performance of the OT test, in general, and current …

Application Of Visual Cues On 3d Dynamic Visualizations For Engineering Technology Students And Effects On Spatial Visualization Ability: A Quasi-Experimental Study, Petros Katsioloudis, Vukica Jovanovic, Mildred Jones
STEMPS Faculty Publications
Several theorists believe that different types of visual cues influence cognition and behavior through learned associations; however, research provides inconsistent results. Considering this, a quasi-experimental study was done to determine if there are significant positive effects of visual cues (color blue) and to identify if a positive increase in spatial visualization ability for students in engineering technology courses is observed. According to the results of this study it is suggested that the use of the specific visual cue (color blue) provides no statistically significant higher scores versus the treatment that did not utilize any visual cues.

Impact Of Optimally Minimizing Delay Times On Safety At Signalized Intersections In Urban Areas, Case Study: The City Of Virginia Beach, Eugene Vida Maina, Albert Forde, R. Michael Robinson
VMASC Publications
Optimally minimizing delay times at signalized intersections can significantly improve both traffic flow and safety. However, most traffic flow optimizing tools do not measure the effect on safety. This study uses nonlinear programming (NLP) algorithms to optimally minimize delay times and employs both Safety performance functions (SPFs) and empirical Bayes (EB) before-after methodology to measure the impact on safety presented as a Crash Modification Factor (CMF). A crash modification factor (CMF) is a multiplicative factor used by transportation practitioners to compute the expected number of crashes at specific study site(s) after a countermeasure has been proposed or is implemented. Using …

Crowds are a part of everyday public life, from stadiums and arenas to school hallways. Occasionally, pushing within the crowd spontaneously escalates to crushing behavior, resulting in injuries and even death. The rarity and unpredictability of these incidents provides few options to collect data for research on the prediction and prevention of hazardous emergent behaviors in crowds. This study takes a close look at the way states of agitation, such as panic, can spread through crowds. Group composition—mainly family groups composed of members with differing mobility levels—plays an important role in the spread of agitation through the crowd, ultimately affecting …

Considering this, a quasi-experimental study was conducted to identify the existence of statistically significant effects on sectional view drawing ability due to the impacts of music. In particular, the study compared the use of three different types of music; classical, rock, heavy metal and whether a significant difference exists towards sectional view drawing ability, among engineering technology students. According to the results of this study it is suggested that the impact of music provides no …
Low Budget Forensic Drive Imaging Using Arm Based Single Board Computers, Eric Olson, Narasimha Shashidhar
Low Budget Forensic Drive Imaging Using Arm Based Single Board Computers, Eric Olson, Narasimha Shashidhar
Journal of Digital Forensics, Security and Law
Traditional forensic analysis of hard disks and external media typically involves a powered down machine and “dead analysis” of these devices. Forensic acquisition of hard drives and external media has traditionally been by one of several means: standalone forensic duplicator; using a hardware write-blocker or dock attached to a laptop, computer, workstation, etc., forensic operating systems that live boot from a USB, CD/DVD or virtual machines with preinstalled operating systems. Standalone forensics acquisition and imaging devices generally cost thousands of dollars. In this paper, we propose the use of single board computers as forensic imaging devices. Single board computers can …

In-The-Wild Residual Data Research And Privacy, William B. Glisson, Tim Storer, Andrew Blyth, George Grispos, Matt Campbell
Journal of Digital Forensics, Security and Law
As the world becomes increasingly dependent on technology, researchers in both industry and academia endeavor to understand how technology is used, the impact it has on everyday life, the artifact life-cycle and overall integrations of digital information. In doing so, researchers are increasingly gathering 'real-world' or 'in-the-wild' residual data, obtained from a variety of sources, without the explicit consent of the original owners. This data gathering raises significant concerns regarding privacy, ethics and legislation, as well as practical considerations concerning investigator training, data storage, overall security and data disposal. This research surveys recent studies of residual data gathered in-the-wild and …
Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili
Bytewise Approximate Matching: The Good, The Bad, And The Unknown, Vikram S. Harichandran, Frank Breitinger, Ibrahim Baggili
Journal of Digital Forensics, Security and Law
Hash functions are established and well-known in digital forensics, where they are commonly used for proving integrity and file identification (i.e., hash all files on a seized device and compare the fingerprints against a reference database). However, with respect to the latter operation, an active adversary can easily overcome this approach because traditional hashes are designed to be sensitive to altering an input; output will significantly change if a single bit is flipped. Therefore, researchers developed approximate matching, which is a rather new, less prominent area but was conceived as a more robust counterpart to traditional hashing. Since the conception …

Security Analysis Of Mvhash-B Similarity Hashing, Donghoon Chang, Somitra Sanadhya, Monika Singh
Journal of Digital Forensics, Security and Law
In the era of big data, the volume of digital data is increasing rapidly, causing new challenges for investigators to examine the same in a reasonable amount of time. A major requirement of modern forensic investigation is the ability to perform automatic filtering of correlated data, and thereby reducing and focusing the manual effort of the investigator. Approximate matching is a technique to find “closeness” between two digital artifacts. mvHash-B is a well-known approximate matching scheme used for finding similarity between two digital objects and produces a ‘score of similarity’ on a scale of 0 to 100. However, no security …
