Crgb_Mem: At The Intersection Of Memory Forensics And Machine Learning, Aisha Ali-Gombe, Sneha Sudhakaran, Ramyapandian Vijayakanthan, Golden G. Richard

Faculty Publications

Mobile malware's alarming sophistication and pervasiveness have continued to draw the attention of many cybersecurity researchers. Particularly on the Android platform, malware trojans designed to steal user PIIs, crypto miners, ransomware, and on-device fraud continue to infiltrate the primary Google store market and other secondary markets. While much effort has been put in place by the research community and industry to curb this menace since 2012, malware authors have consistently found ways to circumvent the existing detection and prevention mechanisms. Largely this remains so because of the restrictiveness of the feature set used in building the current classification models. Thus, …

Faculty Publications

Willow wood presents a real interest for biomass pyrolysis due to its fast growth, renewability, and high energy density. Following the pyrolysis of willow wood in an inert atmosphere, a multi-fuel gaseous mixture was obtained, with the following composition (by volume): 38.20% CO/21.87% H2/17.44% CH4/1.15% O2/17.15% CO2/4.19% N2. The propagation of laminar premixed flames in these multifuel mixtures with air was investigated numerically for initial temperatures from 298 to 500 K, initial pressures from 1 to 20 bar, and fuel equivalence ratios between 0.60 and 2.00. The combustion of these gaseous mixtures as free laminar premixed flames was simulated by …

Pattern-Based Target Selection For Treatment Of Irregular Past Tense: A Single-Case Experimental Design For Children With Dld, Kirsten M. Hannig Russell, Amy Wilder, Julie L. Wambaugh

Faculty Publications

Purpose: Many children with developmental language disorder (DLD) demonstrate difficulty inflecting irregular past tense verbs. We evaluated using phonological-based patterns (i.e., schemas) to select targets for treatment of irregular verb inflection for children with DLD. We hypothesized this approach would result in acquisition of treated verbs, generalization to untreated verbs within the same phonological schema, and increased use of correct irregular verbs in naturalistic contexts.

Method: Treatment was provided to three 7-year-old participants with DLD in the context of multiple baseline design across behaviors and participants. Phonological schemas included vowel change, final alveolar, and dual change irregular verbs. Treatment was …

Water-Based Settlements At The Confluence: San Gabriel & El Guique New Mexico, José A. Rivera Ph.D

Faculty Publications

After more than four centuries, the acequias of New Mexico continue to serve agricultural purposes in spite of economic, demographic, political, technological, and environmental changes. Their origins can be traced to early settlements at the confluence of the Río Grande and the Río Chama, the birthplace of Iberian acequia irrigation in New Mexico. This article demonstrates the value of water in high desert environments where mountain snowpacks feed rivers and streams that are diverted to irrigate fields in places such as San Gabriel (now Chamita) and El Guique. These and other acequia communities in the region should be protected for …

The Great Rebellion And The Mystery Of Lawlessness In 2 Thessalonians 2,1-12, Ranko Stefanovic

Faculty Publications

This article provides an expository study of 2 Thessalonians 2,1-12 in which Paul delineates the Christian history from his day until the Second Coming. The apostle contends that the Christian history will be characterized by a great spiritual rebellion against God organized by Satan. The apostle points to the central roles of two entities in that great rebellion, which he defines in terms of “the man of lawlessness” as the agent of Satan and “the restrainer” who for some time holds back the full revelation of that lawless figure on the world scene. Bible commentaries offer various proposal on the …

Packets-To-Prediction: An Unobtrusive Mechanism For Identifying Coarse-Grained Sleep Patterns With Wifi Mac Layer Traffic, Dheryta Jaisinghani, Nishtha Phutela

Faculty Publications

A good night’s sleep is of the utmost importance for the seamless execution of our cognitive capabilities. Unfortunately, the research shows that one-third of the US adult population is severely sleep deprived. With college students as our focused group, we devised a contactless, unobtrusive mechanism to detect sleep patterns, which, contrary to existing sensor-based solutions, does not require the subject to put on any sensors on the body or buy expensive sleep sensing equipment. We named this mechanism Packets-to-Predictions(P2P) because we leverage the WiFi MAC layer traffic collected in the home and university environments to predict “sleep” and “awake” periods. …

The Future Of International Law Freedom Of Journalism: A Transitional Justice Framework, Edward L. Carter

Faculty Publications

The overwhelming majority of digital and physical attacks on journalists are done with impunity. This results in lower-quality journalism, less scrutiny of government, and less healthy societies and democracies. The international human rights law concept of transitional justice could bolster collective will and inform legal mechanisms to combat such impunity. Judges and investigators in several recent cases of attacks on journalists have invoked transitional justice concepts, including truth-telling, criminal investigations and prosecutions, reparations, and institutional reforms to guarantee non-recurrence. These mechanisms should be fully implemented to protect journalism at local, national, and international levels.

Identity And Rituals Of South Asian Communities In Africa: A Missiological Analysis, Andrew Tompkins

Faculty Publications

There is a sizable Indian population throughout sub-Saharan Africa. A majority of the Indian population are practicing Hindus. For Hindus, ritual is a significant part of their faith tradition, often the most important. In Africa, where they are a minority, Indians often cling to these rituals to maintain their identity as both Indian and Hindu. To share Christ among Indians in Africa, a robust understanding of ritual is required. While many Africans have thought about ritual from their cultural backgrounds, Seventh-day Adventist Africans have yet to do as much reflection on the role of ritual and faith. Adventists in Africa …

Caveat Emptor: Scan Quality Of Elsevier's Digital Backfile Pdf Collection, Gregory M. Nelson, Paul K.J. Robbins, Dennis L. Eggett

Faculty Publications

Scans of journal articles originally published in print, otherwise known as digital journal backfiles, benefit library patrons by providing near instantaneous access to important older information and full-text searchability. Digital backfiles can serve as a reliable surrogate for their corresponding print journals which could be removed from the library, freeing up space for other patron services. Both benefits are realized when the scanned articles are of sufficient clarity to replace the print versions. Several studies have analyzed small and subject-narrow sections of Elsevier’s digital backfile. This article contains a scan-quality analysis from 1578 journals that contain nearly four million articles …

Accurate Covariance Estimation For Pose Data From Iterative Closest Point Algorithm, Rick H. Yuan, Clark N. Taylor, Scott L. Nykl

Faculty Publications

One of the fundamental problems of robotics and navigation is the estimation of the relative pose of an external object with respect to the observer. A common method for computing the relative pose is the iterative closest point (ICP) algorithm, where a reference point cloud of a known object is registered against a sensed point cloud to determine relative pose. To use this computed pose information in downstream processing algorithms, it is necessary to estimate the uncertainty of the ICP output, typically represented as a covariance matrix. In this paper, a novel method for estimating uncertainty from sensed data is …

Cost Estimation Trends For Major Defense Acquisition Programs, Sammantha Jones, Edward D. White, Jonathan D. Ritschel, Shawn M. Valentine

Faculty Publications

The authors use both descriptive and inferential techniques to investigate average and standard deviation trends in cost estimates for major defense acquisition programs (MDAPs) grouped into decades from the 1970s to 2010s. For total program-cost-growth factors (CGFs), the 2010s exhibited lower CGFs compared to the 1990s. For the program-acquisition-unit cost (PAUC) CGFs, the 2010s appear lower than the 1990s and borderline lower than the 1970s. A statistically significant decreasing trend in the standard deviations of total program CGFs throughout the decades was identified. This lowering variability trend also appeared for PAUC CGFs from the 1980s onward. This finding appears to …

Integrating Lipid Metabolism, Pheromone Production And Perception By Fruitless And Hepatocyte Nuclear Factor 4, Jie Sun, Wen Kan Liu, Calder Ellsworth, Qian Sun, Yufeng Pan, Yi Chun Huang, Wu Min Deng

Faculty Publications

Sexual attraction and perception are crucial for mating and reproductive success. In Drosophila melanogaster, the male-specific isoform of Fruitless (Fru), FruM, is a known master neuro-regulator of innate courtship behavior to control the perception of sex pheromones in sensory neurons. Here, we show that the non-sex-specific Fru isoform (FruCOM) is necessary for pheromone biosynthesis in hepatocyte-like oenocytes for sexual attraction. Loss of FruCOM in oenocytes resulted in adults with reduced levels of cuticular hydrocarbons (CHCs), including sex pheromones, and show altered sexual attraction and reduced cuticular hydrophobicity. We further identify Hepatocyte nuclear factor 4 (Hnf4) as a key target of …

Faculty Publications

Recurrent outbreaks of zoonotic infectious diseases highlight the importance of considering the interconnections between human, animal, and environmental health in disease prevention and control. This has given rise to the concept of One Health, which recognizes the interconnectedness of between human and animal health within their ecosystems. As a contribution to the One Health approach, this study aims to develop an indicator system to model the facilitation of the spread of zoonotic diseases. Initially, a literature review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement to identify relevant indicators related to One Health.

Scalable Preparation Of The Masked Acyl Cyanide Tbs-Mac, Haley Hinton, Jack Patterson, Jared Hume, Krunal Patel, Julie Pigza

Faculty Publications

This paper describes the three-step synthesis of TBS-MAC, a masked acyl cyanide (MAC) and a versatile one-carbon oxidation state three synthon. We have developed a scalable and detailed synthesis that involves: (1) acetylation of malononitrile to form the sodium enolate, (2) protonation of the enolate to form acetylmalononitrile, and (3) epoxidation of the enol, rearrangement to an unstable alcohol, and TBS-protection to form the title compound. Both the sodium enolate and acetylmalononitrile are bench-stable precursors to the intermediate hydroxymalononitrile, which can be converted to other MAC reagents beyond TBS by varying the protecting group (Ac, MOM, EE, etc.).

Intrinsic Point Defects (Vacancies And Antisites) In Cdgep2 Crystals, Timothy D. Gustafson, Nancy C. Giles, Peter G. Schunemann, Kevin T. Zawilski, Kent L. Averett, Jonathan E. Slagle, Larry E. Halliburton

Faculty Publications

Cadmium germanium diphosphide (CdGeP₂) crystals, with versatile terahertz-generating properties, belong to the chalcopyrite family of nonlinear optical materials. Other widely investigated members of this family are ZnGeP₂ and CdSiP₂. The room-temperature absorption edge of CdGeP₂ is near 1.72 eV (720 nm). Cadmium vacancies, phosphorous vacancies, and germanium-on-cadmium antisites are present in as-grown CdGeP₂ crystals. These unintentional intrinsic point defects are best studied below room temperature with electron paramagnetic resonance (EPR) and optical absorption. Prior to exposure to light, the defects are in charge states that have no unpaired spins. Illuminating a CdGeP_{2 …}

A Comparison Of Quaternion Neural Network Backpropagation Algorithms, Jeremiah Bill, Bruce A. Cox, Lance Champaign

Faculty Publications

This research paper focuses on quaternion neural networks (QNNs) - a type of neural network wherein the weights, biases, and input values are all represented as quaternion numbers. Previous studies have shown that QNNs outperform real-valued neural networks in basic tasks and have potential in high-dimensional problem spaces. However, research on QNNs has been fragmented, with contributions from different mathematical and engineering domains leading to unintentional overlap in QNN literature. This work aims to unify existing research by evaluating four distinct QNN backpropagation algorithms, including the novel GHR-calculus backpropagation algorithm, and providing concise, scalable implementations of each algorithm using a …

A Multi-Scale Method For Combined Design And Dispatch Optimization Of Nuclear Hybrid Energy Systems Including Storage, Daniel Hill, Dawson Mccrea, An Ho, Matthew Memmott, Kody Powell, John Hedengren

Faculty Publications

Reliable, carbon-free power generation is increasing in importance. Nuclear-renewable hybrid energy systems (NHES) are a potential solution for current generation challenges, but design and dispatch optimization for these systems remains challenging particularly when stochastic effects, long time horizons and nonlinear modeling are needed. This work presents a multi-scale method for combining the design and dispatch optimization problems for nonlinear NHES over long time horizons. Rather than treating the entire horizon as a single optimization problem, a large number of combined optimization problems are solved for shorter samples of the horizon resulting in distributions of optimal capacities for each of the …

Academic Success And Retention Pathway For Mechanical Engineering Major, Paul Akangah, Henry Ivuawuogu, Adeola Morawo, Andrea Nana Ofori-Boadu

Faculty Publications

Evaluating student success in higher education relies heavily on Grade Point Average (GPA), a measure determined by faculty through formative and summative assessments. Faculty determine these grades throughout the student's academic career. Society often equates higher grades with greater intelligence and engagement, assuming students work independently. Grades are also a means to measure or quantify learning and intellectual progress during students' academic careers. However, when students resort to unsanctioned online resources (UORs) using applications like Chegg, Course Hero, and Slader, the student may obtain good grades, but understanding and learning are grossly sacrificed. This study investigates the performance of 100 …
