A Highly Tunable Sub-Wavelength Chiral Structure For Circular Polarizer, Menglin L.N. Chen, Li (Lijun) Jun Jiang, Wei E.I. Sha, Tatsuo Itoh

Electrical and Computer Engineering Faculty Research & Creative Works

Chiral structures are composed of periodically arranged asymmetric particles. The asymmetry of chiral particles results in extraordinary properties like negative refraction index, giant optical activity and circular dichroism. Consequently, they have applications in super lens and various polarization controllers. There are two types of chiral structures, namely planar and 3D structures. The planar ones usually have three- or fourfold rotational symmetry, which limits the polarization tuning capability. On the other hand, the 3D prototypes are difficult to fabricate and measure. Here, we propose a highly tunable sub-wavelength 3D chiral structure. It can be conveniently manufactured on the single-layer double-side printed …

Negotiating The Baptist Influence In East Texas: Examining ‘Multiple Reflections’ To Disrupt The Local Sociopolitical Stage, Brandon L. Fox

The Journal of Faith, Education, and Community

The purpose of this paper is to examine multiple reflections (Ronai, 1995) of a White, southern male navigating through and of the influence of the Missionary Baptist church in rural East Texas. While East Texas continues to engage in social struggle through economics and identity politics, the author desires to examine the role of the Missionary Baptist church in maintaining certain power structures and borders (Anzaldúa, 2012). The author critically reflects on intersections of culture, religion, and power to engage in naming (Freire, 1970) covert means that influence the sociopolitical complex (Conquergood, 2002). Themes across autoethnographic reflections are identified and …

Designing Laboratories For Small Scale Digital Device Forensics, Richard P. Mislan, Tim Wedge

Annual ADFSL Conference on Digital Forensics, Security and Law

The ubiquity of small scale digital devices (SSDD), the public’s ever increasing societal dependence on SSDD, and the continual presence of SSDD at all types of crime scenes, including non-technical and violent crimes, demand a formalized curriculum for the education and training of future cyber forensic examiners. This paper presents the various SSDD forensics labs currently in use and under development for future use at the Purdue University Cyber Forensics Laboratory. The primary objective of each module is to provide specific real-world cases for the learning, comprehension, and understanding of hands-on investigative techniques and methodologies. The purpose of this paper …

Network Forensic Investigation Of Internal Misuse/Crime In Saudi Arabia: A Hacking Case, Abdulrazaq Al-Murjan, Konstantinos Xynos

Annual ADFSL Conference on Digital Forensics, Security and Law

There are ad-hoc guidelines and a limited policy on computer incident response that does not include computer forensic preparation procedures (e.g. logging incidents). In addition, these guidelines do not consider the requirement of Islamic law for admissible evidence at an organisational level in Saudi Arabia. Network forensic investigation might breach the Saudi law if they follow ad-hoc or international digital forensic standards such as Association of Chief Police Officers (ACPO) guidelines. This might put the organisation in a costly situation when a malicious employee sues an Islamic court. This is because the law of Saudi Arabia is complying with Islamic …

Religion In Schools? The Importance Of Recognizing The Impact Of Religious Experiences, Kimberly K. Ilosvay Edd

The Journal of Faith, Education, and Community

The school environment is a place of forced contact between diverse peoples. It is the perfect environment to nurture the diverse identities present. The influences on identity (i.e., language, ethnicity, religion, etc.) shape how students perceive information and learn. Some educators use these influences to help them instruct students. However, often overlooked is the influence of religious practices on language use and behavior in classrooms. This paper argues that the significance of understanding the religious practices of students is equally as important for planning instruction as knowing any other aspect of their culture, (i.e., the students’ native language(s)). Framed by …

Using Climate Information For Drought Planning, Taryn Finnessey, Michael Hayes, Jeff Lukas, Mark D. Svoboda

National Drought Mitigation Center: Faculty Publications

Historically, drought has been responded to rather than prepared for, yet studies have illustrated that proactive investment in drought risk management reduces impacts and overall response costs. One key element of preparedness is the use of sufficient climate information for monitoring, forecasting, and tracking long-term trends. In the face of a changing climate and increasing variability, these types of data are even more critical for planning and overall resiliency. The systematic use of these data to inform the drought planning component of drought risk management is a relatively recent development. Actionable science has direct applicability for planning and decision-making, and …

Lava Flow Hazard Assessment For The Idaho National Laboratory, Idaho Falls, And Pocatello, Idaho, U.S.A., Elisabeth Gallant

USF Tampa Graduate Theses and Dissertations

This study presents a probabilistic lava flow hazard assessment for the Idaho National Laboratory (INL) and the cities of Idaho Falls and Pocatello, Idaho. The impetus of this work is to estimate the conditional probability that a lava flow on the eastern Snake River Plain (ESRP) will impact the areas of interest given the formation of a new volcanic vent in the region. A list of 288 eruptive events, derived from a previously published inventory of 506 surface and 32 buried vents, was created to reduce the biasing of spatial density maps towards eruptions with multiple dependent vents. Conditional probabilities …

Phenomenological Mssm Interpretation Of Cms Searches In Pp Collisions At √S=7 And 8 Tev, M M. Baarmand, Vallary Bhopatkar, Stefano Colafranceschi, Marcus Hohlmann, H Kalakhety, D Noonan, Tuhin S. Roy, Francisco X. Yumiceva, Cms Collaboration

Aerospace, Physics, and Space Science Faculty Publications

Searches for new physics by the CMS collaboration are interpreted in the framework of the phenomenological minimal supersymmetric standard model (pMSSM). The data samples used in this study were collected at s=7 and 8 TeV and have integrated luminosities of 5.0 fb−1and 19.5 fb−1, respectively. A global Bayesian analysis is performed, incorporating results from a broad range of CMS supersymmetry searches, as well as constraints from other experiments. Because the pMSSM incorporates several well-motivated assumptions that reduce the 120 parameters of the MSSM to just 19 parameters defined at the electroweak scale, it is possible to assess the results of …

Evolution From The Plasmon To Exciton State In Ligand-Protected Atomically Precise Gold Nanoparticles, Meng Zhou, Chenjie Zeng, Yuxiang Chen, Shuo Zhao, Matthew Y. Sfeir, Manzhou Zhu, Rongchao Jin

Publications and Research

The evolution from the metallic (or plasmonic) to molecular state in metal nanoparticles constitutes a central question in nanoscience research because of its importance in revealing the origin of metallic bonding and offering fundamental insights into the birth of surface plasmon resonance. Previous research has not been able to probe the transition due to the unavailability of atomically precise nanoparticles in the 1-3 nm size regime. Herein, we investigate the transition by performing ultrafast spectroscopic studies on atomically precise thiolate-protected Au₂₅, Au₃₈, Au₁₄₄, Au₃₃₃, Au_∼520 and Au_∼940 nanoparticles. Our results …

Structure And Physical Conditions In The Huygens Region Of The Orion Nebula, C. R. O'Dell, Gary J. Ferland, M. Peimbert

Physics and Astronomy Faculty Publications

Hubble Space Telescope images, MUSE maps of emission lines, and an atlas of high velocity resolution emission-line spectra have been used to establish for the first time correlations of the electron temperature, electron density, radial velocity, turbulence, and orientation within the main ionization front of the nebula. From the study of the combined properties of multiple features, it is established that variations in the radial velocity are primarily caused by the photoevaporating ionization front being viewed at different angles. There is a progressive increase of the electron temperature and density with decreasing distance from the dominant ionizing star θ^{1 …}

Physics and Astronomy Faculty Publications

We study the internal radial gradients of stellar population properties within 1.5 R_e and analyse the impact of galaxy environment. We use a representative sample of 721 galaxies with masses ranging between 10⁹ M_⊙ and 10^11.5 M_⊙ from the SDSS-IV survey MaNGA. We split this sample by morphology into early-type and late-type galaxies. Using the full spectral fitting code firefly, we derive the light and mass-weighted stellar population properties, age and metallicity, and calculate the gradients of these properties. We use three independent methods to quantify galaxy environment, namely the Nth nearest neighbour, the …

Making Scholarly Activity Available To The Masses: The Scaffolding Of Scholarship Throughout The Undergraduate Curriculum, Michael Savarese, Trent R. Brown, Carolyn Culbertson, Anna Carlin

Florida Statewide Symposium: Best Practices in Undergraduate Research

Florida Gulf Coast University’s Quality Enhancement Plan (QEP) focuses on improving student critical thinking, information literacy, and written communication. Rather than developing these skills through traditional methods (e.g., through senior-level, independent research), these learning outcomes are practiced through scholarly experiences. Traditional undergraduate scholarship manifests itself through terminal, senior capstone or research experiences. These, because of the economy of scale, typically reach a minority of students, often just honors students or those approached by faculty mentors. At FGCU, however, scholarly experiences are a part of the curriculum throughout the program of study, and scaffolded to build greater depth and sophistication. Presented …

Space Environment Effects Of Ionizing Radiation On Seed Germination And Growth, Alex Souvall, Takuyuki Sakai, Takahiro Shimizu, Yuta Takahashi, Midori Morikawa, Shusuke Okita, Akihiro Nagata, Toshihiro Kameda, Shaunda Wenger, Jr Dennison

Presentations

An initial limited set of tests of germination rate and seed growth in a controlled environment have identified statistically significant differences between control samples and seed flown in a Russian LEO research flight. Most significantly, average seed germination of space borne seeds was 2 days less than the 6 days for the control seeds. Modification of the seed coat leading to enhanced rate of water uptake, as a result of radiation from the space environment or abrasion due to launch vibrations, is hypothesized to cause early germination. High school students will conduct growth tests on seeds exposed to simulated space …

Plasma Deflection Test Setup For E-Sail Propulsion Concept, Allen Andersen, Jason Vaughn, Todd Schneider, Ken Wright

Presentations

The Electronic Sail or E-Sail is a novel propulsion concept based on momentum exchange between fast solar wind protons and the plasma sheath of long positively charged conductors comprising the E-Sail. The effective sail area increases with decreasing plasma density allowing an E-Sail craft to continue to accelerate at predicted ranges well beyond the capabilities of existing electronic or chemical propulsion spacecraft. While negatively charged conductors in plasmas have been extensively studied and flown, the interaction between plasma and a positively charged conductor is not well studied. We present a plasma deflection test method using a differential ion flux probe …

High Altitude Dependence Of Ionizing Radiation From Cosmic Rays, Zack Gibson, Akihiro Nagata, Midori Morikawa, Takuyuki Sakai, Takahiro Shimizu, Yuta Takahashi, Shusuke Okita, Raul Ramirez, Alexandra Hughlett, Toshihiro Kameda, Jr Dennison

Posters

The flux of ionizing radiation from cosmic background sources has been measured as a function of altitude using a compact Geiger counter aboard a high altitude balloon. The payload was developed by researchers from University of Tsukuba and flown under the auspices of the Utah State Get-Away-Special (GAS) team. Dose rate, temperature, pressure, humidity, altitude and position data were acquired during a ~4 hour flight up to an altitude of 32 km in August 2016. The altitude reached by this balloon was more than 5 times the height of that reached by Victor Hess’ experiment in 1912, which later won …

The STEM retention model being evaluated and modified is Learning …

Seasonal Temperature Variations Controlling Cave Ventilation Processes In Cueva Larga, Puerto Rico, Rolf Vieten, Amos Winter, Sophie Friederike Warken, Andrea Schrӧder-Ritzrau, Thomas E. Miller, Denis Scholz

International Journal of Speleology

Two years of cave monitoring investigate ventilation processes in Cueva Larga, a tropical cave in Puerto Rico. The cave is 1,440 m long with a large main passage (about 120,000 m³). Cave air pCO₂ in the main passage varies seasonally, between 600 ppm in winter and 1,800 ppm in summer. The seasonal variability in cave pCO₂ permits the estimation of a cave air exchange time of 36 ± 5 days and a winter ventilation rate of 3,300 ± 1,000 m³/day for the main cave passage. Calculations of virtual temperature and differences between cave and …

Optimal Portfolio Using A Genetic Algorithm, Hector Reyes

Fall Interdisciplinary Research Symposium

Distributing the amount of money to invest in each stock of a portfolio, while maximizing profit and minimizing risk is key. This project applied the method of a genetic algorithm in order to select an optimal portfolio. A genetic algorithm generates solutions to optimization problems using techniques inspired by natural evolution. A five stock, five years’ portfolio was utilized in order to demonstrate the efficiency of a genetic algorithm. The most important steps of this method were the fitness function and the crossover. The fitness function is a formula that determined the effectiveness of the portfolio distribution; it returned a …

Academic And Psychosocial Outcomes Of A Physical Activity Program With Fourth Graders: Variations Among Schools In Six Urban School Districts, Cheryl L. Somers, Erin E. Centeio, Noel Kulik, Alex Garn, Jeffry Martin, Bo Shen, Mariane Fahlman, Nathan A. Mccaughtry

Kinesiology, Health and Sport Studies

The purpose was to examine academic achievement, school attachment, and peer acceptance before and after a comprehensive school-based physical activity program (CSPAP) with 378 children in 12 fourth-grade classrooms across six schools in primarily low-socioeconomic status (SES) districts of a large Midwestern metropolitan area. Both personal and normative rate of academic achievement improvement metrics were used. Overall, all students showed personal math and reading growth. However, effects varied by types of achievement indicator and comparison group, revealing noteworthy school-level demographic and implementation characteristics that are inextricably intertwined with program effectiveness and student growth. Implications, especially for minimizing generalizations, are significant.
