Energy Surety For Us Army Buildings In Afghanistan, Eric D. Reisweber Aug 2014

Energy Surety For Us Army Buildings In Afghanistan, Eric D. Reisweber

STAR Program Research Presentations

Energy access and reliability are high priorities at the U.S. Army bases in Afghanistan. Using photovoltaic (PV) arrays can help diversify the systems that supply energy to a given area increasing energy safety, security, reliability and sustainability—and thus improving energy surety. PV systems, which convert incoming solar radiation into usable electric power, may be a wise choice for bases in the Middle East because the solar resource is relatively constant and abundant. Solar resource refers to the amount of solar radiation a given location on earth’s surface receives. The solar resource for two locations were investigated in this study using …


Using Remote Sensing Data To Predict The Spread Of Mosquito Borne Disease, Mary Ellen O'Donnell, Erika Podest Aug 2014

Using Remote Sensing Data To Predict The Spread Of Mosquito Borne Disease, Mary Ellen O'Donnell, Erika Podest

STAR Program Research Presentations

There is interest in how environmental variables derived from satellite data such as temperature, vegetation cover, and precipitation correlate to vector borne disease occurrence such as malaria and dengue fever. This study will be carried out using a decision tree based open source software called Random Forests to find correlations between the remote sensing variables and mosquito abundance. Software will be written in C# to take large amounts of data from the NASA satellite database and automatically format it for the Random Forest Software input. Correlations found, using Random Forests, between disease incidence and the variables can be used as …


San Joaquin River's Sediment Textural Features, Erika Arreguin-Cazarez Aug 2014

San Joaquin River's Sediment Textural Features, Erika Arreguin-Cazarez

STAR Program Research Presentations

The research will be focusing on sediments from Turlock Lake and Riverbank. My focus is to analyze the sediments to know if there are any correlations between the textural features of the sediments between Turlock Lake and Riverbank based on their size. It is expected the environment of the lakes and the rivers has an effect in the changes and if the energy of the water flow also affects the different textural features. The textural features will focus on; roundness, shiny vs. dull, rough vs. smooth, and their shape. The shape is calculated by the three dimensions of the sediment; …


Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio Aug 2014

Wind Speed And Seismic Motion Data Analysis, Margarita Vidrio

STAR Program Research Presentations

The Laser Interferometer Gravitational Wave Observatory (LIGO) was developed to exploit Einstein's prediction of gravitational waves to develop a new way to study the universe. Gravitational waves are detected by observing changes less than 1/10000 of the diameter of a proton in the distances between hanging mirrors that are four kilometers apart within two perpendicular evacuated tubes. These changes in distances between mirrors are produced by gravitational waves from large masses in space, such as colliding black holes. Many factors affect the sensitivity of the interferometer. LIGO’s Physical Environment Monitoring subsystem (PEM) is one method of both eliminating noise and …


Growing Conditions For Algae, Angeles Mora, Tamar Melkonian, Alejandro Calderon-Urrea Aug 2014

Growing Conditions For Algae, Angeles Mora, Tamar Melkonian, Alejandro Calderon-Urrea

STAR Program Research Presentations

With the growing demands of water in California and the increasing cost of fossil fuels to operate water-cleaning equipment, Algae was cultivated in different concentrations of Nitrogen, Phosphorus, and Potassium (NPK) during different trails to identify the best growing conditions for the removal water contaminates. Before testing algae in waste water, the Algae: Dunaliella Primolecta, Chlorella Vulgaris, and Scenedesmus Dimorphus were cultivated in four different media containing distilled water and plant vitamins. The different mediums used include: Orchid Grow More (20-20-20), Miracle Grow (30-10-10), Murashige & Skoog, and Orchid Bloom Boster (11-35-15). As a result of the investigation, the algae, …


Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf Aug 2014

Mother Convict Cichlids Inflict More Bites Upon An Intruder In Hot Temperatures, Jesse L. Heckendorf

STAR Program Research Presentations

Convict cichlids (Archocentrus nigrofasciatus) have developed to be extremely good parents by protecting their brood. Parental care leads to aggressive biting, chasing, and gill flaring to intimidate known predators. In this experiment, we show that environmental factors, such as the changing of temperature in this case, affect a female convict cichlid’s aggression toward caring for her offspring when an intruder is introduced. Females attack more in warmer water.


Injector Configuration And Development Of A Methodology To Scale Between Cold-Flow And Hot-Fire Evaluations, Ilian Angel Rojas, Nils Sedano Aug 2014

Injector Configuration And Development Of A Methodology To Scale Between Cold-Flow And Hot-Fire Evaluations, Ilian Angel Rojas, Nils Sedano

STAR Program Research Presentations

The Air Force Research Laboratory (AFRL) is undertaking a program to improve the development of a gas-centered swirl coaxial liquid injector. The injector in a liquid rocket engine atomizes and mixes the fuel with the oxidizer to produce efficient and stable combustion that will improve stability performance and provide the required thrust for the rocket engine without endangering hardware durability. The rocket injector has been experimentally investigated by using a combination of methodologies called cold-flow and hot-fire testing which have been scaled by other laboratory facilities. The AFRL identified few condition parameters for hot-firing testing that could be simulated through …
