Mouse Vs. Machine: The Game, Cafferty Aiko Frattarelli

Senior Projects Spring 2017

Many modern video games built by big name companies are coded by a group of people together using, and possibly modifying, an already designed game engine. These games usually have another group of people creating the artwork. In this project, I coded and designed a video game from scratch, as well as created all the artwork used in the game. The player controls a mouse character who fights a variety of monsters. In order to create the complexity of the game, I implement basic neural networks as the enemy artificial intelligence, i.e. the decision making process of the enemy. It …

Beyond Homographies: Exploration And Analysis Of Image Warping For Projection In A Dome, Kai Joseph Malowany

Senior Projects Spring 2017

The goal of this project is to provide multiple approaches for warping a flat image tofit the curvature of a geodesic dome, to be presented as an immersive, Augmented Reality (AR) environment. This project looks to develop an algorithmic method of warping any image to fit perspective distortion for a dome-like surface. Despite fairly common usage in planetarium methods and other such shows, there is very little documented method that would allow for the warping of images to fit a curved projection surface. The methods will be explored include using Processing, OpenCV, and fisheye image filters. In addition to the …

Thin Blue Seam, Sebastian Anton-Ojeda

Senior Projects Spring 2017

This performance began as an exploration of liminal spaces in the context of a post-modern world. The lines between a suburban, consumptive society, fraught with binaries and thresholds while on the fringes of nature, were what interested me the most. However, this line of thought quickly took me to far more ancient places, to a view of nature driven by animism and pervaded by spiritual introspection. In Celtic Ireland, to give an example, every stone and river is witness to a myth. The Celts of the old world as described by anthropologist Marie-Louise Sjoestedt are constantly straddling the line between …

Land Trust Response To Renewable Energy Siting Challenges In New York, Collin David Adkins

Bard Center for Environmental Policy

Energy policies promoting energy independence, grid modernization, climate change mitigation, and clean energy standards are a leading driver of land-use change in the United States. This has resulted in an increased pressure to develop land. The recent focus by states to expand renewable energy poses an interesting challenge to organizations dedicated to conserving open space and natural resources, creating a potential tension between competing “green” goals. In response, The Land Trust Alliance, a national organization supporting over 1,100 member land trusts, has recently set a goal to “empower land trusts to encourage the buildout of renewable energy facilities while steering …

An Analysis Of China’S Regional Emissions Trading System: Challenges And Lessons, Ronghui (Kevin) Zhou

Bard Center for Environmental Policy

China, the largest carbon dioxide emitter in the world, has faced environmental pressures both internationally and domestically over the last ten years. In early 2011, the Chinese government approved a carbon emissions trading program in seven cities and provinces, and started planning a national emissions trading framework. This thesis reviews these pilot programs and examines the issues that underlie them. Drawing lessons from the U.S. Acid Rain Program, the European Union’s ETS, and California’s CAT, the three largest emissions trading frameworks in the world, I find that: (1) lack of trades in China’s pilot programs is a consequence of permit …

Climate Change In The Hudson River Estuary: Promoting Adaptation And Resilience Through Stakeholder Engagement In Design And Visualization, Gabrielle S.D. Weiss

Bard Center for Environmental Policy

In response to the growing risk to communities from climate change impacts, Professor Cerra at the Cornell University School of Landscape Architecture developed the Climate Adaptive Design (CAD) program. CAD is being implemented as a partnership between the Hudson River Estuary Program (Estuary Program) and Cornell that utilizes participatory design and visualization to engage communities about planning for future climate impacts. The goal of CAD is to build climate resilience, galvanize community participation and education, and build links to external sources of support including local institutions of higher education. This thesis outlines background for the development of the program and …

Public Perception Of Environmental Programs In The Sierra Gorda Biosphere Reserve, Landa De Matamoros, Queretaro, Mexico, Danielle Marie Salisbury

Bard Center for Environmental Policy

Biological or ecological corridors have recently been sought out as a solution to biodiversity loss due to habitat fragmentation. In eastern Mexico, the Mexican and German governments are collaborating to connect fragmented landscapes and Natural Protected Areas (NPAs) over five states across a Madrean Pine-Oak biodiversity hotspot through the implementation of the Ecological Corridor of the Sierra Madre Oriental (CESMO). One of the ways the CESMO is accomplishing its conservation goals is by extending environmental programs that are currently in place within NPAs to other areas within the corridor, but outside of NPA borders. However, the success of the corridor …

Carbon Stocks In Shade Coffee: Strategies For Enhancing Carbon Storage In Smallholder Systems In Jinotega, Nicaragua, Vanessa Katheryn Kichline

Bard Center for Environmental Policy

Climate change has recently shifted focus to adaptation and mitigation strategies in coffee production. Shade coffee systems, already widely recognized for their contribution to biodiversity and soil conservation, are now drawing attention for their role in carbon storage. Researchers have generally assumed that high carbon storage must come at the expense of reduced crop yields, implying that farmers must choose between sustainability and profit. This study uses field inventories of 70 farms in Jinotega, Nicaragua to estimate this tradeoff in smallholder shade coffee systems. Field inventories were used to develop three typologies representing different shade management strategies in use in …

Utilizing New York State’S Distributive Generation Laws For Affordable Housing Organizations, Reuben Jaffe Goldstein

Bard Center for Environmental Policy

The focus of this report is to assist in the deployment of renewable energy in New York City by creating a framework that affordable housing organizations can use to navigate evolving New York regulations to deploy solar PV to their tenants and reduce their tenants’ utility bills. New York’s regulatory environment is trying to make it easier to deploy solar PV through programs such as Shared Solar Program and Remote Net Metering that provide guidance to those who are currently unable to access solar PV. However, incentivizing Solar PV and distributed generation have disproportionately increased costs for utilities, which has …

To Nudge Or Not To Nudge: Promoting Environmentally Beneficial Behaviors, Emma Jean Cooper

Bard Center for Environmental Policy

In order to mitigate the effects of climate change, humans need to change how they act toward the environment. Unfortunately, as much as we may want to act in ways that would be best for us and for the environment, we often struggle to do just that due to cognitive biases. Nudge theory attempts to remedy this problem by helping us make the decision that would be in our best interests. To explore this issue, I conduct an extended review of the literature to examine how well nudge theory can be applied to the realm of environmental policy. Specifically, I …

Addressing Antibiotic Resistance From Farm-Raised Fish Imported To The United States, Nicholas Ali

Bard Center for Environmental Policy

Misuse of medically important antibiotics in animal production threatens the effectiveness of drugs that are vital in combating disease and infections. Recently, the FDA implemented regulations to limit the use of and access to veterinary drugs. However, these regulations only affect domestic production operations. Because over 90% of seafood consumed in the U.S. is imported from countries with different regulatory standards and because the U.S. has an import inspection rate of less than 1%, antibiotic resistance stemming from imported aquaculture is still a risk that is not sufficiently accounted for. This research investigates how the U.S. has reacted to the …

Quantifying The Effect Of The Shift In Major League Baseball, Christopher John Hawke Jr.

Senior Projects Spring 2017

Baseball is a very strategic and abstract game, but the baseball world is strangely obsessed with statistics. Modern mainstream statisticians often study offensive data, such as batting average or on-base percentage, in order to evaluate player performance. However, this project observes the game from the opposite perspective: the defensive side of the game. In hopes of analyzing the game from a more concrete perspective, countless mathemeticians - most famously, Bill James - have developed numerous statistical models based on real life data of Major League Baseball (MLB) players. Large numbers of metrics go into these models, but what this project …

Competing Theories Of Pitch Perception: Frequency And Time Domain Analysis, Nowell Thacher Stoddard

Senior Projects Spring 2017

Pitch perception is a phenomenon that has been the subject of much debate within the psychoacoustics community. It is at once a psychological, physiological and mathematical issue that has divided scientists for the last 200 years. My project aims to investigate the benefits and shortcomings of both the place theory and time theory approaches. This is done first by a model consistent with the long-standing focus on the frequency domain, and then by expanding to a more modern approach that functions in the time domain.

Content-Aware Image Resizing, Race Darwin Morel

Senior Projects Spring 2017

The purpose of this project is to implement and explore the use of seam carving — a tool used to select and remove “seams” of low-importance pixels from an image in order to reduce its height or width. I also cover the process of seam insertion, creating new seams of pixels to increase the image’s size rather than reducing it. Using these content-aware algorithms, I investigate the process of intelligently resizing an image. Using edge detection, dynamic programming, and pixel manipulation, I push the limits of seam carving and attempt to quantify the qualitative concept of salience.

Plasma Striations In Vacuum Chambers, Loren Hamilton Jackson

Senior Projects Spring 2017

Plasma, often referred to as the fourth state of matter, is ionized gas consisting of positive ions and free electrons. Specifically, a glow discharge is a glowing plasma formed by a voltage across a low pressure gas. The area of the glow discharge of interest in this study is the positive column, a relatively long column of pink, glowing plasma, and its bright and dark striated patterns.

The striated positive column resembles pattern phenomena caused by standing pressure waves. These pressure wave patterns are due to the length of the tube in which they are contained. However, in past plasma …

The Disciple: A Talking Platformer, Benjamin Sernau

Senior Projects Spring 2017

Working in Unity to create a two-dimensional platformer with a Natural Language Generation system, I have considered a new way in which Artificial Intelligence may affect gameplay. The resulting project, The Disciple, takes input from the environment of the game and offers successfully a sentence relevant to what occurs within the game's world. The sentences this system generates are diverse enough so that, while the Natural Language Generation system may restate what it has said, already, it does not utter the same sentence twice in a row. Often, the Natural Language Generation system selects a phrase I have written from …

Modeling Purple Sea Urchin And California Sheephead Populations In Southern California Kelp Forests, Olivia Rachel Williams

Senior Projects Spring 2017

In this project I am modelling the predator-prey relationship between California sheephead and purple sea urchin populations, respectively, in kelp forests off the coast of southern California. The Lotka-Volterra equations explain predator-prey relationships in their most basic form. These equations incorporate a set of biological assumptions that can be unrepresentative of many ecological systems. I will consider alternate models that incorporate variations of the Lotka-Volterra model which may better represent the biology of the purple sea urchins and California sheephead. Using biological characteristics of both species in kelp forests, I will set possible and likely parameters and solve for unknown …

Community Detection For Counter-Terrorism, Patrick Michael Kelly

Senior Projects Spring 2017

Community detection in large networks is a process that has been heavily researched in the past decade due to the the emergence of online social networks. For Twitter, Inc., analyzing terrorists communities is vital in the fight against ISIS recruiters who use the twitter platform to radicalize people around the world. The goal of this project is to develop an algorithm which can accurately detect communities in large networks and to provide textual analysis on the discovered communities. Our algorithm combines the results of two unsupervised clustering algorithms to find communities in a given network. One algorithm uses the structure …

From Random To Organized: The Architecture Of Neural Networks During Development, Avery Isabella Morris

Senior Projects Fall 2017

The brain is constantly changing during development as a result of various stimuli: memories, language, visual patterns and other sensory information. As a result, networks need to have specific learning rules to function being both plastic and stable. In this project, I’ve constructed a mathematical model based on a biological neural network during development. I’ve written differential equations to describe these specific learning rules as well as methods of visual input to the network. I’ve changed my model, using Euler’s method, to create a discrete-time version of this biological phenomenon to implement on the computer. I’ve successfully coded this, using …

Thinking Outside The Box: Computing 3d Volume In 2d, Alexandra D. Morris

Senior Projects Fall 2017

This project explores how to compute 3D volume of cardboard boxes in 2D without a calibrated camera. Computer vision techniques to obtain 3D volume typically require camera calibration, the standard method for mapping 3D points to 2D. We created our own solution that doesn’t rely on camera calibration and obtains the areas of each box with unknown dimensions with the help of a chessboard pattern placed on each box side. The solution is a proportion that given the box area in pixels, chessboard pattern in pixels, and the chessboard pattern in inches, determines the box area in inches. We tested …

Nitrate Loading In The Saw Kill Watershed: Small Watershed Nutrient Dynamics, Answering A Community Question, And Assessing Methodological Approaches, Marco Sebastian Spodek

Senior Projects Spring 2017

Biogeochemical cycles mitigate the movement of nutrients through ecosystems at a variety of scales. Within aquatic systems, nitrogen (N) and phosphorus (P) are especially critical due to their high influence on primary production and decomposition. However, in excess, N and P can pose hazardous ecological effects downstream. Excessive loading of both N and P to waterways can facilitate harmful algal blooms or dead zones in reservoirs and at drainage points. Extensive research over the past half century has shown that the majority of nutrient loading to aquatic systems is the result of anthropogenic land use. While the effects of these …
