Sea Level Change In The Gulf Islands National Park Reserve, Southern British Columbia: Implications For The Interpretation Of Nearshore Archaeological Features, Glenda J. Wyatt

Salish Sea Ecosystem Conference

Sea level along the B.C. coastline has changed dramatically over the past 10,000 years due to isostatic rebound following deglaciation from the Fra ser Glaciation (Clague & James, 2002). In the future, sea levels globally are also predicted to rise according to the Intergovernmental Panel on Climate Change (IPCC) (2014), due to climate change. Lemmen et al. (2008), suggest that in the near future some B.C. coastal communities will have to deal with changes in shorelines due to rising sea levels, and hence erosional patterns, modifications to ecosystems and habitats, and potentially an altered marine food supply. This thesis examines …

Pacific Great Blue Heron Population Monitoring On Vancouver Island And The Surrounding Gulf Islands, Trudy A. Chatwin, Travis Heckford

Salish Sea Ecosystem Conference

The Pacific or Great Blue Heron fannini subspecies winters and breeds on Vancouver Island in locations within 5 km of the marine shoreline. Its visibility and close connection to the Salish Sea make it an important flagship species. Due to population concerns and threats associated with urban development, the Province of BC has coordinated monitoring of Great Blue Heron colonies on Vancouver Island and the adjacent Gulf Islands from 1997 through 2015. Starting in 2005, I trained volunteer stewards and technicians to use a standardized methodology to locate and assess heron colonies, count active nests, determine nest success and follow …

Mathematical Relativity And The Nature Of The Universe, Priscila Reyes

Mathematics Colloquium Series

In this talk, I will be discussing certain space-times, which can be used to model celestial objects and events in the universe. These are solutions to Einstein's field equations, which roughly describe the relation between matter, energy and the geometry of the universe. The concept of time in relation to an observer will be demonstrated. I will also include some interesting phenomena that arise out of the unusual mathematical structure of space-times , such as Lorentz contraction, reverse Cauchy-Schwarz, and the twin paradox.

A Gis Analysis Of Waulsortian-Like Mounds In The Mississippian Of Kentucky And Tennessee, Philip Roberson

Scholars Week

Following a mass extinction nearly 365 million years ago, bryozoans and crinoids replaced corals and stromatoporoids as the dominant framework organisms in reefs and, during the very earliest part of the Carboniferous period, they built reef-like structures that are known from Europe, North America and Africa. They are characterized by large size, a matrix of carbonate mud, and their major framework organisms.

Waulsortian-like mounds occur in geographically isolated patches in outcrop and in the subsurface of central Tennessee and Kentucky where they are associated with hydrocarbon production. These mounds have the same characteristic organisms as the European mounds and do …

Scholars Week

Up-to-date and detailed vegetation map provides critical information for habitat management. In addition, a vegetation map is necessary for the Park’s Fire Management, for classification of fuel types, and for delineation of fire management units. There have been several attempts of vegetation mapping in 1934, 1975 and 1997. Recent advancements in mapping technology and the availability of high resolution Lidar data call for a new vegetation map for the Park’s management team.

In this study, Landsat-8 Operational Land Imager (OLI) imagery, Lidar and geology dataset were applied to vegetation mapping. Habitat types are determined by a combination of geology, aspect …

Change Detection Of Mount Nyiragongo Post Eruption, Molly E. Karnes

Scholars Week

Because of the dangerous nature of volcanic eruptions, it makes them very difficult to study, however this makes them even more important for us to study because of how much destruction they can cause in such a short amount of time. We need to study all parts of an eruption to gain more insight into the specifics of how a volcano works. Having a better understanding of how large of an area is effected by an eruption will allow governments to decide on evacuation procedures. The goal of my project is to answer a very simple question, “How can we …

Landform Mapping Of The Clarks River Alluvial System Using Lidar Dems, Benedict W. Ferguson

Scholars Week

The Clarks River is located in western Kentucky near the city of Benton. It travels through and weathers lacustrine or lake deposits as well as fluvial or river deposits. These deposits are also overlain by loess deposited from the last glacial maximum. Historically, people have taken advantage of these rich deposits for agriculture which has led to increased settlement. With increased settlement, the river has experienced alteration. The west fork of the Clarks River has been channelized while the east fork of the Clarks River has managed to remain un-channelized and has since been allowed to run relatively freely.

Molecular Sensitivity And Selectivity Of Metal Nanoparticles Decorated Graphene As ‘Smart’ Surface-Enhanced Raman Scattering (Sers) Platforms [Hybrid Poster 1-A], Alexander Banaszak, Tyler Smith

Posters-at-the-Capitol

Raman scattering signal enhancement that uses graphene as support, graphene-enhanced Raman scattering (GERS), is a recent phenomenon. It can produce clean and reproducible Raman signals of chemical molecules with significantly enhanced signal intensity in contrast to traditional surface- (SERS) and tip- enhanced Raman scattering (TERS) techniques. While enhancement in SERS and TERS arise due to the electromagnetic mechanism, GERS also relies on a chemical mechanism and therefore shows unique molecular sensitivity and selectivity. In this work, we developed graphene materials decorated with noble metal (silver and gold) nanoparticles for detection of different chemical molecules e.g. methylene blue (MB) and rhodamine …

Leveraging existing U.S. regulatory frameworks, as well as international organizations, will dramatically shorten the time needed to develop an effective Space Traffic Management concept. Both the Department of Defense and the Department of Transportation have been working with the U.S. Congress to define and develop a Space Traffic Management concept that will allow the Office of Commercial Space Launch to begin a new mission that will help to ensure the safety and resilience of the space domain. Outside observers can easily see forward progress toward this, still, undeveloped concept. This paper explores potential final U.S. Space Traffic Management concepts that …

Minimum Number Of Distinct Eigenvalues Of Graphs, Shahla Nasserasr

Mathematics Colloquium Series

For a simple graph G on n vertices, a real symmetric nxn matrix A is said to be compatible with G, if for different i and j, the (i; j) entry of A is nonzero whenever there is an edge between the vertices i and j, it is zero otherwise. The minimum number of distinct eigenvalues, when minimum is taken over all compatible matrices with G, is denoted by q(G). In this talk, a survey of some known and new results about q(G) is presented.

An Analysis Of Archival Observations Made Of Galactic Supernova Remnants By The Chandra X-Ray Observatory, Daniel M. Rush, Haley E. West

Posters-at-the-Capitol

Since its launch in 1999, the Chandra X-ray Observatory has spurred explosive growth in the study of Galactic supernova remnants (SNRs) due to its unsurpassed angular resolution (1 arcsecond at 1 keV) and its moderate sensitivity. We are currently analyzing archival observations made by Chandra of two particular classes of SNRs: mixed-morphology SNRs (which feature contrasting center-filled thermal X-ray morphologies with shell-like radio morphologies) and synchrotron X-ray SNRs (which feature X-ray spectra dominated by synchrotron emission). To illustrate some of our initial results, we present spatially resolved spectroscopic analyses of the mixed-morphology SNR 3C 397 and the synchrotron X-ray dominated …

P-26 Detection Of Counterfeit Antimalarial Drugs By Sers, Getahun Merga, P. Shepard, M. Trujillo, J. Camden

Celebration of Research and Creative Scholarship

Substandard antimalarial drugs are a major problem to the health of citizens in developing countries, and it is likely that the problem persists due to the lack of means to detect substandard drugs. Various colorimetric techniques have been implemented to determine if a drug contains the stated active ingredient or not, but vibrational spectroscopies such as NIR and Raman can be used to more reliably quantify the amount of active ingredient. The use of Raman, however, has been limited by the presence of significant sample fluorescence that interferes with detection of the SERS signals of the active ingredients. Thus, we …

Smartsignplay: Lily Learns American Sign Language, Jeremiah Doody

DHI Digital Projects Showcase

Many children are born either wholly or partially deaf, leaving parents to wonder how they can communicate with, and teach their child. For a hearing parent, unfamiliar with American Sign Language (ASL), traditional methods can be exasperating. Additional methods are helpful to reinforce this learning process. The teaching method needs to be effective, yet easy enough for a 2 year old to pick up. Likewise, the premise needs to actually hold the child’s attention. SmartSignPlay was proposed as an interactive smartphone, or tablet, game designed to make teaching ASL easier and fun. The game was to be point and click, …
