Analyzing Global Cyber Attack Correlates Through An Open Database, Brady Benjamin Aiello

Master's Theses

As humanity becomes more reliant on digital storage and communication for every aspect of life, cyber attacks pose a growing threat. However, cyber attacks are generally understood as individual incidents reported in technological circles, sometimes tied to a particular vulnerability. They are not generally understood through the macroscopic lens of statistical analysis spanning years over several countries and sectors, leaving researchers largely ignorant of the larger trends and correlates between attacks. This is large part due to the lack of a coherent and open database of prominent attacks. Most data about cyber attacks has been captured using a repository of …

There Has Never Been A 'Timber War', Greg King

Humboldt Journal of Social Relations

There has never been a 'timber war' in northwestern California, but rather premeditated and ongoing attacks against the forests, and against the people who would protect them. This paper provides a historic examination of redwood logging and protection efforts since 1850.

Mineral Warfare: The Dark Side Of Technology And International Mediation, Priyanka Basnyat

Master's Theses

Conflict surrounding the extraction and trade of natural resources is not an uncommon phenomenon. Especially in the case of the Democratic Republic of Congo (DRC), which has historically suffered from the negative impacts of the resource curse since their mineral wealth was first discovered by their Colonial administrators. The importance of Congo’s minerals has fluctuated over the years but has peaked during recent times, as their use in technological advancements are becoming more vital. The global demand for these mineral ores have sky rocketed and consequentially, the largely informal trade has benefitted certain rebel groups, playing a pivotal role in …

Elliptic Cryptosystem, Elizabeth Dettrey

UNLV Theses, Dissertations, Professional Papers, and Capstones

The elliptic cryptographic algorithm first presented in a paper by E. F. Dettrey and E. A. Yfantis is examined and explained in this thesis. The algorithm is based on the group operations of a set of points generated from an ellipse of arbitrary radii, and arbitrary center in the case of the generalized version, modulo a large prime. The security of the algorithm depends on the difficulty of solving a discrete logarithm in the groups used by this algorithm. While the elliptic cryptographic algorithm is not the most secure among the discrete logarithm based paradigm of cryptosystems for a given …

These devices have been shown to be insecure in general especially at categories that include any of the following: low-cost, home use, small business, and factory automation. There are continuing research and news reports showing Internet connected devices contain backdoors of various origins whether they be placed intentionally or are discovered as vulnerabilities. These types of devices are of concern because they are critical …

Evaluating The Efficacy Of Using Geomorphology As A Surrogate To Benthic Habitat On The Miami Terrace, Kim D. Smith

HCNSO Student Theses and Dissertations

The deep-sea is a vast and relatively sparsely characterized domain. As little as 0.01% of deep-sea benthic habitats have been characterized in detail. Characterizing the distribution of organisms and environmental components of the deep-sea is pivotal to the creation and implementation of successful resource management. Benthic habitat maps are a good method to inventory and characterize deep-sea habitats. Recent advances in technology, such as multibeam sonar and remotely operated vehicles (ROVs), have allowed for greater understanding of these ecosystems. As it is difficult and expensive to collect data deep-sea benthic community composition, environmental surrogates of biological data would be economically …

A Critical Analysis Of Mystery In Videogames, Ali Alkhafaji

College of Computing and Digital Media Dissertations

Historically, videogame research has focused on how different videogame attributes (like challenge, fantasy, control, goals, etc.) impact the player experience. This type of research is important because it can provide insight into how to design more enjoyable videogames. However, very little exists within the current literature that focuses on mystery and its impact on the player experience. This dissertation is concerned with providing the research community with a better understanding of how mystery manifests in videogames and consequently impacts the player experience, specifically curiosity and motivation. To this end, the research questions are: 1. How do players experience mystery in …

Diagnostic Platform For Current Health Status Monitoring, Albert S. Benight, Megan M. Koslen, Matthew W. Eskew

Student Research Symposium

Our approach is based on physical measurements of blood plasma and exploits the plethora of information contained in the human plasma proteome, as a reporter of human health status. The assay involves collection and analysis ofthermograms of plasma from human blood measured by differential scanning calorimetry (DSC).

Plasma thermograms arise from the temperature-induced denaturation profile of proteins within blood plasma measured by DSC. This insightful measurement thereby provides a snapshot of the current state of the human plasma proteome which directly informs on overall systemic health. Such measurements have been shown to be highly accurate and sensitive indicators of health …

Cuando La Vida Era Tranquila: Land Use And Livelihood Changes Following The Construction Of The Chan 75 Dam In Nance Del Risco, Bocas Del Toro, Patrick Mckenzie

Independent Study Project (ISP) Collection

The Ngobe are Panama’s most populous indigenous group. While the Ngobe that live in the comarca have land and resource rights, those that live immediately outside of it do not. This issue has been exacerbated by the creation of Palo Seco Forest Reserve which has removed all land rights from the Ngobe living within it. In order to meet its growing demand for energy, Panama is expanding its hydroelectric sector. One such hydroelectric dam built by AES is Chan 75. However, Chan 75 has had a controversial history, especially regarding its treatment of the Ngobe people of the corregimiento Nance …

Boosted Hidden Markov Models For Malware Detection, Aditya Raghavan

Master's Projects

Digital security is an important issue today, and efficient malware detection is at the forefront of research into building secure digital systems. As with many other fields, malware detection research has seen a dramatic increase in the application of machine learning algorithms. One machine learning technique that has found widespread application in the field of pattern matching and malware detection is hidden Markov models (HMMs). Since HMM training is a hill climb technique, we can often significantly improve a model by training multiple times with different initial values. In this research, we compare boosted HMMs (using AdaBoost) to HMMs trained …

Thin Film Carbon Nanofuses For Permanent Data Storage, Kevin Robert Laughlin

Theses and Dissertations

We have fabricated nanofuses from thin-film, arc-evaporation carbon for use in permanent data storage. Thin film carbon fuses have fewer fabrication barriers and retain the required resistivity and structural stability to work as a data storage medium. Carbon thin films were characterized for their electrical, microstructural, and chemical bonding properties. Annealing the thin-film carbon in an argon environment at 400°C reduced the resistivity from about 4*10^-2 Ω cm as deposited down to about 5*10^-4 Ω cm, allowing a lower blowing voltage. Nanofuses with widths ranging from 200 nm down to 60 nm were fabricated and tested. They blow …

The spatial resolution of the observations encompasses a spectrum over 4 orders of magnitude from O(10¹ m) to O(10⁵ m), and …

Higher Energy Gap Control Of Fluorescence In Conjugated Polymers, Chien-Hung Chiang

LSU Doctoral Dissertations

Chemo- and biosensors based on fluorescent conjugated polymer benefit from greater detection sensitivity due to amplification of the electronic perturbations produced by analyte binding. This amplification stems from the exciton-transporting properties of conjugated polymers. A conventional design paradigm relies on the analyte binding events which generate sites of lower energy relative to the polymer energy: either fluorescence quenching sites (turn-off sensors) or bathochromically shifted fluorophores (turn-on sensors). In both type sensors, the excitons migrate to the lower-energy site created by analyte binding.

This dissertation primarily focused the investigation of an alternative paradigm when analyte binding creates higher energy gap sites …

Mitigating The Effects Of Cyber Attacks And Human Control In An Autonomous Intersection, Karl C. Bentjen

Theses and Dissertations

Widespread use of fully autonomous vehicles is near. However, the desire for a human to maintain control, even if limited, of a vehicle will likely never fully subside. Protocols to safely and efficiently manage reservation-based intersections with a mixture of fully autonomous, semi-autonomous, and non-autonomous vehicles exist such as AIM, SemiAIM, and H-AIM. Missing from these protocols is persistent human control of semi-autonomous vehicles in approaching and navigating autonomous intersections without the use of traditional signals. This thesis offers a proof-of-concept of a reservation-based protocol with necessary extensions required for human control in semi-autonomous vehicles. Desired is a protocol that …

Behavior Flexibility For Autonomous Unmanned Aerial Systems, Taylor B. Bodin

Theses and Dissertations

Autonomous unmanned aerial systems (UAS) could supplement and eventually subsume a substantial portion of the mission set currently executed by remote pilots, making UAS more robust, responsive, and numerous than permitted by teleoperation alone. Unfortunately, the development of robust autonomous systems is difficult, costly, and time-consuming. Furthermore, the resulting systems often make little reuse of proven software components and offer limited adaptability for new tasks. This work presents a development platform for UAS which promotes behavioral flexibility. The platform incorporates the Unified Behavior Framework (a modular, extensible autonomy framework), the Robotic Operating System (a RSF), and PX4 (an open- source …

Near Earth Space Object Detection Utilizing Parallax As Multi-Hypothesis Test Criterion, Joseph C. Tompkins

Theses and Dissertations

The US Strategic Command (USSTRATCOM) operated Space Surveillance Network (SSN) is tasked with Space Situational Awareness (SSA) for the US military. This system is made up of Electro-Optic sensors such as the Space Surveillance Telescope (SST) and Ground-based Electro-Optical Deep Space Surveillance (GEODSS) as well as RADAR based sensors such as the Space Fence. While Lockheed Martin’s Space Fence is very adept at detecting & tracking objects in Low Earth Orbit (LEO) below 3000 Km in height [1], gaps remain in the tracking of Resident Space Objects (RSO’s) in Geosynchronous Orbits (GEO) due to limitations associated with the implementation of …

Outlier Classification Criterion For Multivariate Cyber Anomaly Detection, Alexander M. Trigo

Theses and Dissertations

Every day, intrusion detection systems catalogue millions of unsupervised data entries. This represents a “big data” problem for research sponsors within the Department of Defense. In a first response to this issue, raw data capture was transformed into usable vectors and an array of multivariate techniques implemented to detect potential outliers. This research expands and refines these techniques by implementing a Chi-Square Q-Q plot-based classification criteria for outlier detection. This methodology has been implemented into an R-based programming solution that allows for a refined and semi-automated user experience for intelligence analysts. Moreover, two case analyses are performed that illustrate how …

Radiological Decontamination In The Urban Environment Utilizing An Irreversible Wash-Aid Recovery System, Keith A. Sanders

Theses and Dissertations

The radioactive fallout from the Fukushima Daiichi nuclear reactors accident and the ongoing threat of nuclear or radioactive terrorism have forced the need for urban radiological decontamination into the forefront. Many of the established decontamination techniques are not ideally suited for the urban milieu. One of the keys to maximize the effectiveness of long-term remediation and recovery in the urban environment is immediate mitigation within a few days of the incident and before a rain event. The Integrated Wash-Aid, Treatment, and Emergency Reuse System (IWATERS) provides a potentially safe and effective method for early responders and remediation teams to perform …

Expected Coverage (Excov): A Proposal To Compare Fuzz Test Coverage Within An Infinite Input Space, Evan V. Swihart

Theses and Dissertations

A Fuzz test is an approach used to discover vulnerabilities by intentionally sending invalid inputs to a system for the purpose of triggering some type of fault or unintended effect that renders the system vulnerable to an exploit. Fuzz testing is an important cyber-testing technique used to find and fix vulnerabilities before they are exploited. The fuzzing of military data links presents a particular challenge because existing fuzzing tools cannot be easily applied to these systems. As a result, the tools and techniques used to fuzz these links vary widely in sophistication and effectiveness. Because of the infinite, or nearly …

The "Double Standard" Of Nonproliferation: Regime Type And The U.S. Response To Nuclear Weapons Program, Alina Shymanska

International Journal of Nuclear Security

There is no doubt that the NPT regime is far from being equal for all states involved. As the predominant hegemonic power since WWII, the United States plays a major role in deciding the fates of non-great power proliferators. This article tries to find the logical explanation of the phenomenon whereby some nuclear proliferators are absolved regardless of their active accumulation of nuclear arsenals while others are labeled as “rogue states” and ordered to disarm. The article suggests that a particular proliferator’s political regime could affect the way in which its state is approached by the U.S., known for its …

All spectra were calibrated using a methanol reference spectrum generated by SpectraPlot using the HITRAN Database. The frequency uncertainty is estimated as 0.002 cm^-1. Two peaks at 976.69 and 1003.50 cm^-1 were assigned to ν₁₈ and ν₂₆ bands respectively. Supporting calculations of the anharmonic vibrational frequencies and rotational constants were performed at the MP2/cc-pVTZ level of theory. Two specific motions were assigned to the vibrational modes ν₁₈ and ν₂₆. A spectrum of the ν₂₆ band was …

Water Scarcity: Sudan, Catherine Priebe

Global Issues in Public Health

Water scarcity is an environmental global problem that will only become more pressing as time goes on. It is a public health issue that affects every continent, although certain areas of the world are facing more serious water scarcity than others such as Sudan. Populations that are more vulnerable to the effects of water scarcity are the poor, women, children, and those living in areas of political unrest. For example, South Sudan’s urban water systems have been damaged during recent warfare. Water scarcity is also an issue that disproportionately affects women who are forced from a young age to travel …
