Marine & Environmental Sciences Faculty Articles
Previous research evaluating hydrocarbon toxicity to corals and coral reefs has generally focused on community-level effects, and results often are not comparable between studies because of variability in hydrocarbon exposure characterization and evaluation of coral health and mortality during exposure. Toxicity of the polycyclic aromatic hydrocarbon 1-methylnaphthalene to the coral Porites divaricata was assessed in a constant exposure toxicity test utilizing a novel toxicity testing protocol uniquely applicable to shallow-water corals, which considered multiple assessment metrics and evaluated the potential for post-exposure mortality and/or recovery. Acute and subacute effects (gross morphological changes, photosynthetic efficiency, mortality, and histologic cellular changes) were …

Marine & Environmental Sciences Faculty Articles
The damping of short gravity-capillary waves (Bragg waves) due to surfactant accumulation under low wind speed conditions results in the formation of natural sea slicks. These slicks are detectable visually and in synthetic aperture radar (SAR) imagery. Surfactants are produced by natural life processes of many organisms, such as bacteria, phytoplankton, seaweed, and zooplankton. By using DNA analysis, we are able to determine the relative abundance of surfactant-associated bacteria in the sea surface microlayer and the subsurface water column. A method to reduce contamination of samples during collection, storage, and analysis (Kurata et al., 2016; Hamilton et al., 2015) has …

A Principal Component Analysis Of Vertical Temperature Profiles For Tracking Movements Of Large Pelagic Fishes, Kathryn G. Carmody, Arthur Mariano, David Kerstetter
Marine & Environmental Sciences Faculty Articles
Pop-up satellite archival tag (PSAT) technology that records depth, temperature, and light-level data has expanded the understanding of free-swimming behavior for numerous pelagic animals. Astronomical algorithms using these light-level data have allowed geolocation estimates of daily longitude and latitude. However, many pelagic animals have a crepuscular behavior pattern in which individuals are at depths below the photic layer during the day, thus precluding the use of traditional light-based movement algorithms for geolocation in such species as swordfish. A principal component analysis (PCA) of temperature profiles is described herein that utilizes depth and temperature data rather than light to estimate the …

In aquatic environments, what one observes during the day can differ substantially by night. The species composition and associated ecological processes that occur during the day are often different than night. In polar seas and at great depths, “night” can span, months, years, and beyond. Teleosts and elasmobranchs have evolved unique sensory and behavioral modalities for living in darkness. As a consequence, fishers have adopted unique strategies for exploiting fish at night or in dark systems. We propose that neglecting the night has led to an incomplete understanding of aquatic organismal ecology, population/community dynamics, and ecosystem function with consequences for …

Using Logbook Data To Determine The Immediate Mortality Of Blue Sharks (Prionace Glauca) And Tiger Sharks (Galeocerdo Cuvier) Caught In The Commercial U.S. Pelagic Longline Fishery, Derek R. Dapp, Charlie Huveneers, Terence I. Walker, John Mandelman, David Kerstetter, Richard D. Reina
Marine & Environmental Sciences Faculty Articles
Commercial fisheries are recognized as one of the greatest threats to shark populations worldwide, but factors affecting the likelihood of shark mortality during fishery capture are poorly understood. We used the U.S. pelagic fishery logbook data from 1992 through 2008 to quantify the effects of several variables (fisheries regulatory periods, geographic zone, target catch, and sea surface temperature) on mortality of blue sharks (Prionace glauca) and tiger sharks (Galeocerdo cuvier). Mortality rates and trends in both species closely matched those recorded from other sources, and therefore indicated that the data on sharks discarded dead and discarded …

Measuring Cybersecurity Competency: An Exploratory Investigation Of The Cybersecurity Knowledge, Skills, And Abilities Necessary For Organizational Network Access Privileges, Richard Nilsen
CCAC Theses and Dissertations
Organizational information system users (OISU) that are victimized by cyber threats are contributing to major financial and information losses for individuals, businesses, and governments. Moreover, it has been argued that cybersecurity competency is critical for advancing economic prosperity and maintaining national security. The fact remains that technical cybersecurity controls may be rendered useless due to a lack of cybersecurity competency of OISUs. All OISUs, from accountants to cybersecurity forensics experts, can place organizational assets at risk. However, that risk is increased when OISUs do not have the cybersecurity competency necessary for operating an information system (IS). The main goal of …

Marine & Environmental Sciences Faculty Articles
We examined the unmanipulated performance of students under real classroom conditions in order to assess the effect of a technology-enhanced hybrid learning approach to second language, (L2) instruction on beginning and advanced Spanish language learners. This research focused on the transition period of technology implementation when the entire section of Spanish of a modern language department of a liberal arts university transitioned from traditional face-to-face instruction, to a technology-enhanced hybrid learning approach with concurrent reduction in face-to-face classroom hours. This implementation provided an opportunity to compare the performance of students prior to and during the transition to hybrid model of …
Automated Feature Engineering For Deep Neural Networks With Genetic Programming, Jeff T. Heaton
Automated Feature Engineering For Deep Neural Networks With Genetic Programming, Jeff T. Heaton
CCAC Theses and Dissertations
Feature engineering is a process that augments the feature vector of a machine learning model with calculated values that are designed to enhance the accuracy of a model’s predictions. Research has shown that the accuracy of models such as deep neural networks, support vector machines, and tree/forest-based algorithms sometimes benefit from feature engineering. Expressions that combine one or more of the original features usually create these engineered features. The choice of the exact structure of an engineered feature is dependent on the type of machine learning model in use. Previous research demonstrated that various model families benefit from different types …
Examining The Effects Of Distractive Multitasking With Peripheral Computing In The Classroom, Jaime Eduardo Puente
Examining The Effects Of Distractive Multitasking With Peripheral Computing In The Classroom, Jaime Eduardo Puente
CCAC Theses and Dissertations
The growing use of information and communication technologies (ICTs) in college campuses has dramatically increased the potential for multitasking among students who have to juggle classes, school assignments, work, and recreational activities. These students believe that they have become more efficient by performing two or more tasks simultaneously. The use of technology, however, has changed the student’s ability to focus and attend to what they need to learn. Research has shown that multitasking divides students’ attention, which could have a negative impact on their cognition and learning. The purpose of this study was to examine the effects of distractive multitasking …
A Runtime Verification And Validation Framework For Self-Adaptive Software, David B. Sayre
A Runtime Verification And Validation Framework For Self-Adaptive Software, David B. Sayre
CCAC Theses and Dissertations
The concepts that make self-adaptive software attractive also make it more difficult for users to gain confidence that these systems will consistently meet their goals under uncertain context. To improve user confidence in self-adaptive behavior, machine-readable conceptual models have been developed to instrument the adaption behavior of the target software system and primary feedback loop. By comparing these machine-readable models to the self-adaptive system, runtime verification and validation may be introduced as another method to increase confidence in self-adaptive systems; however, the existing conceptual models do not provide the semantics needed to institute this runtime verification or validation. This research …
Pulsar Search Using Supervised Machine Learning, John M. Ford
Pulsar Search Using Supervised Machine Learning, John M. Ford
CCAC Theses and Dissertations
Pulsars are rapidly rotating neutron stars which emit a strong beam of energy through mechanisms that are not entirely clear to physicists. These very dense stars are used by astrophysicists to study many basic physical phenomena, such as the behavior of plasmas in extremely dense environments, behavior of pulsar-black hole pairs, and tests of general relativity. Many of these tasks require information to answer the scientific questions posed by physicists. In order to provide more pulsars to study, there are several large-scale pulsar surveys underway, which are generating a huge backlog of unprocessed data. Searching for pulsars is a very …

Reducing The Download Time In Stochastic P2p Content Delivery Networks By Improving Peer Selection, Nicholas Hays
Reducing The Download Time In Stochastic P2p Content Delivery Networks By Improving Peer Selection, Nicholas Hays
CCAC Theses and Dissertations
Peer-to-peer (P2P) applications have become a popular method for obtaining digital content. Recent research has shown that the amount of time spent downloading from a poor performing peer effects the total download duration. Current peer selection strategies attempt to limit the amount of time spent downloading from a poor performing peer, but they do not use both advanced knowledge and service capacity after the connection has been made to aid in peer selection. Advanced knowledge has traditionally been obtained from methods that add additional overhead to the P2P network, such as polling peers for service capacity information, using round trip …
Improved Detection For Advanced Polymorphic Malware, James B. Fraley
Improved Detection For Advanced Polymorphic Malware, James B. Fraley
CCAC Theses and Dissertations
Malicious Software (malware) attacks across the internet are increasing at an alarming rate. Cyber-attacks have become increasingly more sophisticated and targeted. These targeted attacks are aimed at compromising networks, stealing personal financial information and removing sensitive data or disrupting operations. Current malware detection approaches work well for previously known signatures. However, malware developers utilize techniques to mutate and change software properties (signatures) to avoid and evade detection. Polymorphic malware is practically undetectable with signature-based defensive technologies. Today’s effective detection rate for polymorphic malware detection ranges from 68.75% to 81.25%. New techniques are needed to improve malware detection rates. Improved detection …
Data Masking, Encryption, And Their Effect On Classification Performance: Trade-Offs Between Data Security And Utility, Juan C. Asenjo
Data Masking, Encryption, And Their Effect On Classification Performance: Trade-Offs Between Data Security And Utility, Juan C. Asenjo
CCAC Theses and Dissertations
As data mining increasingly shapes organizational decision-making, the quality of its results must be questioned to ensure trust in the technology. Inaccuracies can mislead decision-makers and cause costly mistakes. With more data collected for analytical purposes, privacy is also a major concern. Data security policies and regulations are increasingly put in place to manage risks, but these policies and regulations often employ technologies that substitute and/or suppress sensitive details contained in the data sets being mined. Data masking and substitution and/or data encryption and suppression of sensitive attributes from data sets can limit access to important details. It is believed …

Individualized Instruction As A Faculty Training Strategy For Technology Integration, Jennifer Merritt
CCAC Theses and Dissertations
It is inevitable that campus-based higher education will adopt some form of a hybrid learning approach. For schools and their faculty members, this means the acknowledgment and acceptance of these changes are required. Campus-based higher education faculty members wish to change how they teach courses due to societal demands to better suit the next generation of students. Initially, schools began offering new technology to faculty that wished to use the technology; however, over the years, due to the demands of competition with other schools and next generation, tech-savvy students entering academia, schools are starting to require the use of technology …
A Heuristic Approach To Creating Technological Fair Use Guidelines In Higher Education, Jerry L. Roper
A Heuristic Approach To Creating Technological Fair Use Guidelines In Higher Education, Jerry L. Roper
CCAC Theses and Dissertations
Higher education has experienced challenges defining and implementing copyright compliance. Confusion among faculty and staff appears to be common regarding copyright and fair use. The original copyright doctrine was drafted over 200 years ago, which predates practically all technological advances that have and will continue to occur. Change is slow and onerous with most legislation; there is not much possibility the small amendments made to the law will be able to keep pace with the continual technological evolution. Further, judges are citing precedents in court rulings of copyright disputes that were made using the best interpretation of the law, even …

A Study Of Human-Machine Interface (Hmi) Learnability For Unmanned Aircraft Systems Command And Control, Tom Haritos
CCAC Theses and Dissertations
The operation of sophisticated unmanned aircraft systems (UAS) involves complex interactions between human and machine. Unlike other areas of aviation where technological advancement has flourished to accommodate the modernization of the National Airspace System (NAS), the scientific paradigm of UAS and UAS user interface design has received little research attention and minimal effort has been made to aggregate accurate data to assess the effectiveness of current UAS human-machine interface (HMI) representations for command and control. UAS HMI usability is a primary human factors concern as the Federal Aviation Administration (FAA) moves forward with the full-scale integration of UAS in the …
Strategies For Combining Tree-Based Ensemble Models, Yi Zhang
Strategies For Combining Tree-Based Ensemble Models, Yi Zhang
CCAC Theses and Dissertations
Ensemble models have proved effective in a variety of classification tasks. These models combine the predictions of several base models to achieve higher out-of-sample classification accuracy than the base models. Base models are typically trained using different subsets of training examples and input features. Ensemble classifiers are particularly effective when their constituent base models are diverse in terms of their prediction accuracy in different regions of the feature space. This dissertation investigated methods for combining ensemble models, treating them as base models. The goal is to develop a strategy for combining ensemble classifiers that results in higher classification accuracy than …
