Polarization Dependent Spectral Analysis Reveals Dipole Alignment and Intermolecular Coupling in Anthradithiophene Organic Semiconducting Crystals

Creator:: Lam, Andrew
Abstract:: Organic photovoltaics are being explored as the next generation material for semiconducting and optoelectronic devices but are limited by their stability and efficiency. One new candidate is crystallized Anthradithiophene (ADT), which is a promising photo-voltaic material due to its high quantum yield and adjustable side groups. The side derivatives TES-F,...

Wireless Multi-Sensor Patch for Wind Turbine Impact Detection

Creator:: Wilson, Calder
Abstract:: Bird and bat collisions with wind turbines are a problem that needs to be better quantified for its impact to be fully understood. This thesis documents portions of the design of a sensor patch module for use on wind turbines blades to detect impacts caused by birds and bats. This...

Multivariate Vegetation Mapping -- Code and Data

Creator:: Henderson, Emilie B.
Abstract:: This data set contains RCode designed for mapping correlated vegetation summary variables via univariate (modified random forest regression) and multivariate (random forest nearest neighbor) methods. It also contains a small vegetation plot dataset to illustrate the type of information needed to support such an analysis.

Investigating synergistic effects of climate and land-use change on the pollination of a tropical plant, Heliconia tortuosa

Creator:: Dowd, Claire E.
Abstract:: Loss of biodiversity due to the effects of climate and land-use change may have implications for pollination services. Disruption to phenological synchronicity or a reduction in the overlap in species distributions of plants and their pollinators may reduce floral resources to pollinators, forcing them to move farther distances. If pollinators...

SIMstat: Hardware Design Considerations for Implementing a Low-Cost, Portable Potentiostat

Creator:: Cook, Jacob M.
Abstract:: Electroanalytical techniques allow scientists and engineers to characterize bulk solutions as well as interfaces. Potentiostats are commonly used by researchers in a variety of disciplines to analyze the chemistry which occurs at a working electrode surface. Advancements in microelectronics and the proliferation of open-source designs have allowed researchers to construct...

Modeling hop kilning with respect to energy consumption and drying kinetics

Creator:: Thomas, Matthew W.
Abstract:: Currently, little work has been performed studying energy consumption in hop kilning. This thesis explores drying with an alternative drying schedule that extends the initially elevated drying temperature currently used by growers and examines its impact on drying time and energy use. Extending the time of the initially elevated drying...

A Security Analysis of the Signal Protocol’s Group Messaging Capabilities in Comparison to Direct Messaging

Creator:: Jansen, Matthew L.
Abstract:: Signal is a multimedia messaging application developed by OpenWhisper Systems in 2015 which allows its users to communicate securely between one another through the use of a complex encryption scheme. The set of algorithms used in combination to provide the services of the Signal application to their users is called...

Investigating Calving Areas for Rocky Mountain Elk on the Plumas National Forest: Implications for Land Management

Creator:: Marshall, Abigail C.
Abstract:: Sustainable elk (Cervus canadensis) habitat management on U.S. Forest Service (USFS) lands involves a complex relationship between management practices and ecological processes. A relatively novel Rocky Mountain elk population (Cervus canadensis nelsoni) on the Plumas National Forest (PNF) in northeastern California became established in the early 2000s, but there is...

Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

Creator:: Nichols, Dublin MacCray
Abstract:: Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

Hacking RFID Tags to Produce Economical Soil Moisture Sensors

Creator:: Stoddard, Brett S.
Abstract:: Currently available soil moisture sensors have intrinsic limitations that limit their adoption by industry. Depending on the technology, these limitations may include high costs, battery requirements, precice manual installation, high cost, and/or constrictive legislation that regulates their use. A passive soil moisture sensing system based around RFID technology would allay...
