Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann 2014 California Polytechnic State University - San Luis Obispo

Impact Testing Of Youth-Level Helmets Versus College-Level Helmets, Nicole Hermann

Industrial Technology

With so many studies being conducted on professional football players regarding concussions and other related brain injuries, it’s amazing that such an important demographic has been missed. While NFL players are just as subjected to serious injuries as anyone else or even more so, it is important to remember that these players are outfitted, in most cases, with top-of-the-line equipment -- especially their helmets. If the focus is shifted to a younger demographic, youth football players in middle school and high school, the equipment is far less advanced and in a vast majority of cases, has been previously used by ...

Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta 2014 Morgan State University

Benjamin Banneker's Original Handwritten Document: Observations And Study Of The Cicada, Janet E. Barber, Asamoah Nkwanta

Journal of Humanistic Mathematics

Benjamin Banneker, farmer, mathematician, astronomer, and scientist, is known for his mathematical puzzles, ephemeris calculations, almanacs, his wooden clock, land surveying work, and famous letter on human rights. However, as a naturalist, his scientific and systematic observations of the cicadas are less known. In this paper we publicize Banneker’s naturalistic study of the seventeen-year periodic cycle of the cicada and make available the original handwritten document of his observations. We also introduce the audience of this journal to an intriguing natural problem involving prime numbers.


Geometric Influences Ii: Correlation Inequalities And Noise Sensitivity, Nathan Keller, Elchanan Mossel, Arnab Sen 2014 Bar Ilan University

Geometric Influences Ii: Correlation Inequalities And Noise Sensitivity, Nathan Keller, Elchanan Mossel, Arnab Sen

Statistics Papers

In a recent paper, we presented a new definition of influences in product spaces of continuous distributions, and showed that analogues of the most fundamental results on discrete influences, such as the KKL theorem, hold for the new definition in Gaussian space. In this paper we prove Gaussian analogues of two of the central applications of influences: Talagrand’s lower bound on the correlation of increasing subsets of the discrete cube, and the Benjamini–Kalai–Schramm (BKS) noise sensitivity theorem. We then use the Gaussian results to obtain analogues of Talagrand’s bound for all discrete probability spaces and to ...

Bio-Inspired Surface Engineering For Hydrophobicity, Hua Guo 2014 Edith Cowan University

Bio-Inspired Surface Engineering For Hydrophobicity, Hua Guo

Theses: Doctorates and Masters

Highly evolved, efficient and sophisticated biological systems can be used as models for scientific innovations. This research explored specific surface structures on plant leaves with respect to their hydrophobicity in the context of the often arid Australian climate. The relationships between leaf surface structures and their hydrophobicity could inform the making of artificial surfaces with specially designed hydrophobicity.

Moderate hydrophobicity and strong surface adhesion were discovered on many study plant leaves. Scanning Electron Microscopy (SEM) revealed that their surface morphologies could be categorized into four groups while their water-repellent mechanisms were considered at an individual species level. Specifically, physical models ...


Land Use And Climate Variability Amplify Carbon, Nutrient, And Contaminant Pulses: A Review With Management Implications, Sujay S. Kaushal, Peter M. Mayer, Philippe G. Vidon, Rose M.

Land Use And Climate Variability Amplify Carbon, Nutrient, And Contaminant Pulses: A Review With Management Implications, Sujay S. Kaushal, Peter M. Mayer, Philippe G. Vidon, Rose M. Smith, Micheal J. Pennino, Tamara A. Newcomer, Shuiwang Duan, Claire Welty, Kenneth T. Belt

U.S. Environmental Protection Agency Papers

Nonpoint source pollution from agriculture and urbanization is increasing globally at the same time climate extremes have increased in frequency and intensity. We review >200 studies of hydrologic and gaseous fluxes and show how the interaction between land use and climate variability alters magnitude and frequency of carbon, nutrient, and greenhouse gas pulses in watersheds. Agricultural and urban watersheds respond similarly to climate variability due to headwater alteration and loss of ecosystem services to buffer runoff and temperature changes. Organic carbon concentrations/exports increase and organic carbon quality changes with runoff. Nitrogen and phosphorus exports increase during floods (sometimes by ...


Epistasis In Predator-Prey Relationships, Iuliia Inozemtseva 2014 Georgia Southern University

Epistasis In Predator-Prey Relationships, Iuliia Inozemtseva

Electronic Theses and Dissertations

Epistasis is the interaction between two or more genes to control a single phenotype. We model epistasis of the prey in a two-locus two-allele problem in a basic predator- prey relationship. The resulting model allows us to examine both population sizes as well as genotypic and phenotypic frequencies. In the context of several numerical examples, we show that if epistasis results in an undesirable or desirable phenotype in the prey by making the particular genotype more or less susceptible to the predator or dangerous to the predator, elimination of undesirable phenotypes and then genotypes occurs.


Rollover, Drowning, And Discontinuous Retreat: Distinct Modes Of Barrier Response To Sea-Level Rise Arising From A Simple Morphodynamic Model, Jorge Lorenzo Trueba, Andrew Dale Ashton 2014 Montclair State University

Rollover, Drowning, And Discontinuous Retreat: Distinct Modes Of Barrier Response To Sea-Level Rise Arising From A Simple Morphodynamic Model, Jorge Lorenzo Trueba, Andrew Dale Ashton

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

We construct a simple morphodynamic model to investigate the long-term dynamic evolution of a coastal barrier system experiencing sea-level rise. Using a simplified barrier geometry, the model includes a dynamic shoreface profile that can be out of equilibrium and explicitly treats barrier sediment overwash as a flux. With barrier behavior primarily controlled by the maximum potential overwash flux and the rate of shoreface response, the modeled barrier system demonstrates four primary behaviors: height drowning, width drowning, constant landward retreat, and a periodic retreat. Height drowning occurs when overwash fluxes are insufficient to maintain the landward migration rate required to keep ...

Air-Quality And Climatic Consequences Of Bioenergy Crop Cultivation, William Christian Porter 2013 Portland State University

Air-Quality And Climatic Consequences Of Bioenergy Crop Cultivation, William Christian Porter

Dissertations and Theses

Bioenergy is expected to play an increasingly significant role in the global energy budget. In addition to the use of liquid energy forms such as ethanol and biodiesel, electricity generation using processed energy crops as a partial or full coal alternative is expected to increase, requiring large-scale conversions of land for the cultivation of bioenergy feedstocks such as cane, grasses, or short rotation coppice. With land-use change identified as a major contributor to changes in the emission of biogenic volatile organic compounds (BVOCs), many of which are known contributors to the pollutants ozone (O3) and fine particulate matter (PM ...

Uranian Moon Investigation With “Hitchhiker” Small Spacecraft, Jeremy Straub, Tyler Hill, Josh Berk, Nick Long

Jeremy Straub

This poster presents a mission concept for exploring the Uranian moon system utilizing two 6-U (30 cm x 20 cm x 10 cm, 8 kg) CubeSat spacecraft which will be deployed from and relay their communications to Earth through a primary spacecraft. This primary spacecraft, part of the Gap- Based Expanding Outer Region Geophysical Explorer (GEORGE) Mission, will initially work in concert with the 6-U CubeSats to create a gravity map of Uranus. Once this is completed, the spacecraft will re-dock so that the primary craft can move the two 6-U CubeSats to their orbit around Miranda to perform imaging ...

Investigating Uranus With George: The Gap-Based Expanding Outer Region Geophysical Explorer Mission, Jeremy Straub, Josh Berk, Tyler Hill, Nick Long

Jeremy Straub

This paper presents an overview of a two-part mission to Uranus and its moons. Key questions about the Uranian system remain unanswered which can and should be resolved by this mission. These include gaining an understanding about the offset of Uranus’s magnetic field and its axial tilt. Additional details about the composition and formation of Uranus’s moons are also desired. The mission will be comprised of a primary craft and three 6-U CubeSats. The CubeSats will initially be deployed in Uranian orbit to perform a characterization of the gravity field of the planet. They will then be moved ...
