A visual representation of how students flow between majors and colleges can aid in this understanding. This thesis will study how a student cohort can be represented in a Sankey Diagram. In this analysis, a student cohort is represented as a weighted, directed, graph, where a vertex represents a distinct class status for a semester and each weighted edge represents the number of students moving …
Passion For Food: Redesigning The Way We Eat, Nicole Chen
Passion For Food: Redesigning The Way We Eat, Nicole Chen
Theses
Where has the passion in food gone? The focus of food has been on the obesity epidemic, as people demand fast, cheap, and easy foods. The symbol of food is no longer seen as a basic need for survival because of the abundance and options of goods. Being unaware of food and its' power to bring and express so many facets of life, has given me the chance to discover areas that could be redesigned. During these past few years learning about food has made me fully understand these processes as a symbiotic relationship. In today's society, what separates people …

Illustrative Neighborhood Redevelopment, Bradley Bethel
Illustrative Neighborhood Redevelopment, Bradley Bethel
Theses
Urban planning is implemented under many theories and purposes. But often times, due to difference in public preferences, plans can become inconsistent and lack harmony with other neighborhoods. Design theories may become muddled in other design theories. Sometimes, even basic design principles are undermined or ignored completely. The city of Buffalo, New York is distinguished by several major characteristics in area planning. However, those plans have been threatened by inconsistent planning from the past sixty years. Only in recent years have plans been sought for more concise methods to preserve the past and establish newer, progressive plans. The Illustrative Neighborhood …

Analysis Of Virtual Environments Through A Web Based Visualization Tool, Ronald Valente
Analysis Of Virtual Environments Through A Web Based Visualization Tool, Ronald Valente
Theses
Virtualization is gaining popularity in corporations as well as academia. This technology provides a large return on investment by providing the ability to consolidate hardware servers into smaller, more efficient virtual machines (VM). With a seemingly negligible cost to deploy a new virtual machine when compared to deploying a physical server, more and more virtual machines get deployed. However, as the number of virtual machine increases, the task of managing and keeping track of them becomes exceedingly cumber- some. With advanced visualization techniques and real-time analysis of virtualization environments, the control over virtual machine sprawl will become more manageable and …

Multimodal Breast Imaging: Registration, Visualization, And Image Synthesis, Karl Baum
Multimodal Breast Imaging: Registration, Visualization, And Image Synthesis, Karl Baum
Theses
The benefit of registration and fusion of functional images with anatomical images is well appreciated in the advent of combined positron emission tomography and x-ray computed tomography scanners (PET/CT). This is especially true in breast cancer imaging, where modalities such as high-resolution and dynamic contrast-enhanced magnetic resonance imaging (MRI) and F-18-FDG positron emission tomography (PET) have steadily gained acceptance in addition to x-ray mammography, the primary detection tool. The increased interest in combined PET/MRI images has facilitated the demand for appropriate registration and fusion algorithms. A new approach to MRI-to-PET non-rigid breast image registration was developed and evaluated based on …
Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones
Egocentric Depth Perception In Optical See-Through Augmented Reality, James Adam Jones
Theses and Dissertations
Augmented Reality (AR) is a method of mixing computer-generated graphics with real-world environments. In AR, observers retain the ability to see their physical surroundings while additional (augmented) information is depicted as simulated graphical objects matched to the real-world view. In the following experiments, optical see-through head-mounted displays (HMDs) were used to present observers with both Augmented and Virtual Reality environments. Observers were presented with varied real, virtual, and combined stimuli with and without the addition of motion parallax. The apparent locations of the stimuli were then measured using quantitative methods of egocentric depth judgment. The data collected from these experiments …
Visualizing The Inner Structure Of N-Body Data Using Skeletonization, Edward Dale, Hans-Peter Bischof
Visualizing The Inner Structure Of N-Body Data Using Skeletonization, Edward Dale, Hans-Peter Bischof
Presentations and other scholarship
N-body simulations solve the n-body problem numerically and determine the trajectories of the n point masses. The result of these calculations is a huge amount of data detailing the positions and other properties of each body such as mass and velocity. To effectively draw conclusions from these data, one must employ scientific visualization to create images and movies that illustrate the structure of the data. We show that the computer animation technique of skeletonization can be applied to the volume data produced by n-body simulations in order to visualize the inner structure of the data. This novel application is compared …

Multimodal Display Techniques With Application To Breast Imaging, Kimberly Rafferty, Karl Baum, Evan Schimdt, Andrzej Krol, Maria Helguera
Articles
Application of a multimodality approach is advantageous for detection, diagnosis and management of breast cancer. In this context, F-18-FDG positron emission tomography (PET), and high-resolution and dynamic contrast-enhanced magnetic resonance imaging (MRI) have steadily gained clinical acceptance. Obtaining the spatial relationships between these modalities and conveying them to the observer maximizes the benefit that can be achieved. Traditionally the registered images are displayed side by side. However, it is believed that a combined MRI/PET display may be more beneficial. The advantage of a combined image lies in our inability to visually judge spatial relationships between images when they are viewed …

Perceptual Display Strategies Of Hyperspectral Imagery Based On Pca And Ica, Hongqin Zhang, David W. Messinger, Ethan Montag
Presentations and other scholarship
This study investigated appropriate methodologies for displaying hyperspectral imagery based on knowledge of human color vision as applied to Hyperion and AVIRIS data. Principal Component Analysis (PCA) and Independent Component Analysis (ICA) were used to reduce the data dimensionality in order to make the data more amenable to visualization in three-dimensional color space. In addition, these two methods were chosen because of their underlying relationships to the opponent color model of human color perception. PCA and ICA-based visualization strategies were then explored by mapping the first three PCs or ICs to several opponent color spaces including CIELAB, HSV, YCrCb, and …
Visualizing The Inner Structure Of N-Body Data, Edward Dale
Visualizing The Inner Structure Of N-Body Data, Edward Dale
Theses
N-body simulations produce a large amount of data that must be visualized in order to extract interesting features. This data consists of thousands of particles, each with a number of properties such as velocity, mass, and acceleration, that are persisted across hundreds of time steps. Rendering these points using traditional means quickly leads to a image that is satu- rated because the number of particles is greater than the number of pixels available. Volume rendering, and particularly splatting, seeks to remedy this and allows one to see inside the volume and discern the inner structure. The definition of inner structure …

N-Body Visualizations, William Mclaughlin
Theses
In the age of technology and information, data calculations and visualizations are key to the communication and understanding of the world in which we live. It is sometimes difficult to display data in a way to make it clear and understanding, or is difficult to calculate the data to be displayed. The N-body problem has elements of both. The N-body problem is a set of N particles representing stars that move in response to the gravitational force generated by the N-1 other particles. There have been many attacks to this problem. The GRAPEcluster Project of RIT has developed software and …
Web-Based 3-D Theatre Seating Charts And Ticket Reservation Application, Patrick Henstebeck
Web-Based 3-D Theatre Seating Charts And Ticket Reservation Application, Patrick Henstebeck
Theses
Seating charts for theatres and stadia have always been an important part of buying tickets to a staged event, despite offering little information about the view from any particular seat. While the internet has increased the potential to provide this information, most official arena websites and online ticket brokers still only provide the standard two-dimensional diagram whose detail is limited to the approximate location of each section and which offers no guidance as to the height or slope of the section, nor any warning of any obstructing objects that would depreciate a seat s true value. The few three-dimensional models …
Experimental Study Of Flow Boiling Heat Transfer And Critical Heat Flux In Microchannels, Wai Keat Kuan
Experimental Study Of Flow Boiling Heat Transfer And Critical Heat Flux In Microchannels, Wai Keat Kuan
Theses
Advancements in microprocessors and other high power electronics have resulted in increased heat dissipation from those devices. In addition, to reduce cost, the functionality of microprocessor per unit area has been increasing. The increase in functionality accompanied by reduction in chip size has caused its thermal management to be challenging. In order to dissipate the increase in heat generation, the size of conventional fin-type heat sinks has to be increased. As a result, the performance of these high heat flux generating electronics is often limited by the available cooling technology and space to accommodate the larger conventional air-cooled heat sinks. …

Study Of Visualizations For N-Body Stellar Models, Christian Gray
Theses
The visualization of large datasets is invaluable to the advancement of scientific knowledge. N-Body problems produced large dataset that present several challenges to visualization. These challenges include over-plotting and self-obscuring data. Using the general visualization framework, Spiegel, five different visualization techniques are explored to solve these problems: slicing, projection, 3D projection, 3D density shells, and direct volume rendering. Each visualization looks to solve the problem in a slightly different manner while all have kernel density estimation as their starting point. While none of the visualization is ground breaking or perfectly solves the problems they do provide new insight allowing for …
