Magic Squares Of Squares Of Order 4 Over Certain Finite Fields, Drew O’Neill Dec 2013

Magic Squares Of Squares Of Order 4 Over Certain Finite Fields, Drew O’Neill

Theses, Dissertations and Culminating Projects

A magic square of order n over a commutative ring R is an n x n matrix such that all the rows, columns, and the two diagonals add up to a fixed sum, which is called the magic sum. If all of the numbers in a magic square are perfect squares in R, it is called a magic square of squares. The rings under consideration in this thesis are either Z or Zp where p is a prime. In this thesis I present methods of constructing magic squares of squares of order 4 from selected ones of order 3. A …


Updated Pressure And Temperature Determinations For The Metapelites Of The Western Hudson Highlands, Ny, Eric W. Sonnenwald Aug 2013

Updated Pressure And Temperature Determinations For The Metapelites Of The Western Hudson Highlands, Ny, Eric W. Sonnenwald

Theses, Dissertations and Culminating Projects

Pelitic sedimentary material was deposited along the eastern margin of North America in the Mesoproterozoic (~1300-1200 Ma) in an active continental arc basin setting and was subsequently metamorphosed during the Ottawan Orogeny (~1080-1030 Ma) as a part of a closing ocean basin between two continents (Volkert and Drake, 1999). The resulting metapelitic gneisses now exposed in the western Hudson Highlands in Harriman State Park, New York were analyzed to determine the sedimentary protolith and the peak metamorphic pressure-temperature (P-T) conditions during the Ottawan Orogeny that affected this region during the final assembly of Rodinia. The protolith, a clay-bearing arkosic sandstone, …


Spectroscopic Investigation Of The Interaction Of Fadh In Dna Photolyase With Uv-Damaged Dna, Kyle Luke Williams May 2013

Spectroscopic Investigation Of The Interaction Of Fadh In Dna Photolyase With Uv-Damaged Dna, Kyle Luke Williams

Theses, Dissertations and Culminating Projects

Skin cancer is the most prevalent malignancy found in humans, with the diagnosis rate continuing to steadily increase. The primary cause of this disease is overexposure to harmful ultraviolet (UV) radiation from sunlight, which can induce damage to the nitrogenous bases in DNA via dimerization. The most prevalent UV-induced photoproducts in DNA are cyclobutane pyrimidine dimers (CPDs), most commonly between adjacent thymidines.

Organisms have implemented methods by which to repair these CPDs, the primary of which are nucleotide excision repair (NER) and photoreactivation by photolyases. Photolyases are blue-light activated flavoproteins that are more efficient at recognizing and repairing CPDs than …


Modeling Amyloid-Ss Self-Assembly : Stability Of On-Pathway Aggregate Formation, Andrew Kevin Mauro May 2013

Modeling Amyloid-Ss Self-Assembly : Stability Of On-Pathway Aggregate Formation, Andrew Kevin Mauro

Theses, Dissertations and Culminating Projects

Protein misfolding and concomitant aggregation towards amyloid formation is the underlying biochemical commonality among a wide range of human pathologies. Amyloid formation involves the conversion of proteins from their native monomeric states (intrinsically disordered or globular) to well-organized, fibrillar aggregates in a nucleation-dependent manner. Understanding the mechanism of aggregation is important not only to gain better insight into amyloid pathology but also to simulate and predict molecular pathways. One of the main impediments in doing so is the highly stochastic nature of interactions that complicates the development of meaningful insights. In this study, we have utilized a well-characterized intermediate along …

Theses, Dissertations and Culminating Projects

This practitioner action research using qualitative techniques of gathering data looks at the experiences of students in a mostly white, upper-middle class suburb who enrolled in a class that integrated mathematics with social justice issues. The researcher designed the curriculum and co-taught the one semester course. The data were collected from pre-interviews, beginning and end of class questionnaires, quick writes, field notes, and end of class focus group interviews with all the students. The author chose a practitioner action research design because he wanted to be an integral part of the study. The cyclical nature of action research allowed him …


Number Theory Applications In Cryptography, Francesca Pizzigoni May 2013

Number Theory Applications In Cryptography, Francesca Pizzigoni

Theses, Dissertations and Culminating Projects

This thesis provides a unique cryptosystem comprised of different number theory applications. We first consider the well-known Knapsack Problem and the resulting Knapsack Cryptosystem. It is known that when the Knapsack Problem involves a superincreasing sequence, the solution is easy to find. Two cryptosystems are designed and displayed in this thesis that allow two parties often called Alice and Bob use a common superincreasing sequence in the encryption and decryption process. They use this sequence and a variation of the Knapsack Cryptosystem to send and receive binary messages. The first cryptosystem assumes that Alice and Bob agree on a shared …


Climate Evolution Of The Antarctic Peninsula Over The Last 1,000 Years : An Environmental Magnetism Analysis Of Two High Resolution Sediment Cores, Brendan Reilly May 2013

Climate Evolution Of The Antarctic Peninsula Over The Last 1,000 Years : An Environmental Magnetism Analysis Of Two High Resolution Sediment Cores, Brendan Reilly

Theses, Dissertations and Culminating Projects

Two marine sediment cores from very different depositional environments, off the coast of western and northeastern Graham Land, Antarctic Peninsula (AP), record high resolution climatic records of the last 1,000 years. This study finds evidence in the sedimentary magnetic signature for a regional shift from warmer to colder climatic conditions around 1100-1400 AD. The first core, from middle Barilari Bay, western AP, displays a shift from seasonally open marine conditions to sub/proximal ice shelf ca. 1100 AD, with evidence for multiple grounding line advances in the magnetic mineral distributions during the first half of the last millennium. Prior to the …

Investigating Planetary Magnetic Fields : 1. Paleosecular Variation And Relative Paleointensity Curves From Maxwell Bay, Antarctica 2. Rock Magnetic And Remanence Properties Of Natural And Synthetic Martian Basalts, Deepa Shah

Theses, Dissertations and Culminating Projects

This thesis study investigates two individual projects to determine the paleomagnetic records from sediment core NBP0502-1B from Maxwell Bay Antarctica and SNC Martian meteorite Yamato-908459. Core NBP0502-1B from Maxwell Bay, South Shetland Islands, recovered a 108 m sedimentary record dating between 14.1-14.8 ka. The core has a silty-clay lithology and a calcite based radiocarbon chronology, making this an ideal site to reconstruct an independently dated record of paleosecular variation (PSV) and relative paleointensity (RPI). The interval 0-72 mbsf displays a normal sedimentary fabric, with Kmjn inclination values nearly vertical and Kint and Kmax distributed within the bedding …


Collocation Error Correction In Web Queries And Text Documents, Alan T. Varghese May 2013

Collocation Error Correction In Web Queries And Text Documents, Alan T. Varghese

Theses, Dissertations and Culminating Projects

Collocations are words in English that occur together frequently. Non-native speakers of English tend to confuse certain terms with other similar terms. This causes one of the terms to be substituted with a term that is not commonly used with the other term. “Powerful tea” is an example of such an odd collocation. In this scenario the more commonly used term is “strong tea”.

This paper proposes an approach called CollOrder to detect such odd collocations in written English. CollOrder also provides suggestions to correct the odd collocate. These suggestions are filtered and ranked as top-k suggestions.

We make use …


Variations Of The Combinatorial Game Tron, Miriam Parnes May 2013

Variations Of The Combinatorial Game Tron, Miriam Parnes

Theses, Dissertations and Culminating Projects

The combinatorial game Tron is a two player game played on a graph, in which players move to adjacent vertices, but cannot move to any vertex which is currently occupied or which has been occupied by either player earlier in the course of the game. It was introduced by Hans Bodlaender, inspired by the Disney movie of the same name. Bodlaender and, later, Tillmann Miltzow considered the complexity of the question of whether a player has a winning strategy in the game. Miltzow also considered an extremal question regarding the ratio of the vertices taken by the second player over …


Proper Connection Of Bipartite Circulant Graphs, Melissa Marie Fuentes May 2013

Proper Connection Of Bipartite Circulant Graphs, Melissa Marie Fuentes

Theses, Dissertations and Culminating Projects

The study of proper edge-colorings of graphs has been a popular topic in graph theory since the work of Vizing. While the proper edge-colorings of entire graphs was the topic of interest when the subject began decades ago, more recent works have focused on the study of properly colored subgraphs, as opposed to proper colorings of graphs as a whole. The types of properly colored subgraphs that we will be most concerned with are paths. The topic of finding certain types of properly colored paths within larger edge-colored graphs, though seemingly specific in nature, has been a topic of much …


Fe(Vi) As A New Chemical Agent For Treatment Of Landfill Leachate, Christopher Gravesen May 2013

Fe(Vi) As A New Chemical Agent For Treatment Of Landfill Leachate, Christopher Gravesen

Theses, Dissertations and Culminating Projects

More than 50% municipal solid waste (MSW) is being disposed of within landfills in the United States. Despite many benefits, landfills inevitably produce highly contaminated wastewater - landfill leachate. Landfill leachate represents one of the most challengeable wastewaters in the world. Refractory organic matters and ammonia nitrogen are two major persistent traditional contaminants in landfill leachate. The contaminants ought to be properly removed prior to discharge into natural water resources.

Ferrate (FeO42-) is a potential water treatment chemical agent in which iron is in its + 6 oxidation state. In engineering practice, Fe(VI) can concurrently function as …


A Historical, Empirical Analysis Of The Relationship Between Urbanization And Stream Baseflow In The Eastern United States, Jared Michael Lopes May 2013

A Historical, Empirical Analysis Of The Relationship Between Urbanization And Stream Baseflow In The Eastern United States, Jared Michael Lopes

Theses, Dissertations and Culminating Projects

The population density of the United States has more than tripled over the last century causing increased urbanization and greater anthropogenic influences in previously rural watersheds. Urbanization leads to increased impervious surfaces and the compaction of soils, both of which combine to reduce infiltration rates. Reduced baseflow can directly limit water availability for approximately half the U.S. population that depends on surficial waters for their drinking water. This project empirically investigated the baseflow-urbanization relationship on a geographic and temporal scale that has not been previously investigated. USGS river gage data in 11 eastern U.S. states (NY south of the Adirondacks, …


Citizens’ Perspectives Of Access To The Decision Making Process And Community Improvement As Determinants Of Brownfields Redevelopment Success, Shevon Jean Letang Jan 2013

Citizens’ Perspectives Of Access To The Decision Making Process And Community Improvement As Determinants Of Brownfields Redevelopment Success, Shevon Jean Letang

Theses, Dissertations and Culminating Projects

Brownfields redevelopment is acclaimed as a successful program that has revitalized struggling urban communities and returned unproductive, underutilized, and abandoned industrial and commercial properties to municipalities’ tax rolls. Despite a major brownfields' redevelopment goal being to improve the communities and their citizens' quality of life, to date, the program has not been evaluated from the mainstreams' perspective as to its impact on their neighborhoods and their quality of life. A survey of 129 citizens from urban, suburban and exsuburban municipalities in Passaic County New Jersey sought to evaluate the social outcomes of three redeveloped projects from the affected mainstreams' perspective. …


Corporate Social Responsibility And The Gold Mining Industry : The Ghana Experience, Aimann Sadik Jan 2013

Corporate Social Responsibility And The Gold Mining Industry : The Ghana Experience, Aimann Sadik

Theses, Dissertations and Culminating Projects

In 2012, the price of gold is sky rocketing due to strong demand and tight supply. Investors have revived their interest in gold investments at the expense of financial assets such as bonds and equities because of the current financial market turbulence. In addition, the trend in price has been fuelled by the strategic reserve holdings decisions by the central banks of advanced western economies to halt the sale of their gold reserves while that of emerging markets are acquiring gold holdings to protect their wealth during a period of global financial crisis. The supply of gold has not responded …
