Carbon Nanotubes Animated, Nicholas Onyemeke
Chemistry Summer Fellows
In this project, I implemented the knowledge about carbon nanotubes into an animated short. The animated short is meant to simplify the research so that anyone can understand regardless of their background in science. The research I did was on how nanotubes can be used in the medical field as a measure to inhibit bacteria growth. A nanotube dye solution was synthesized to inoculate bacteria along with an antibiotic solution with the nanotubes. This was done to observe how well the nanotubes can inhibit bacteria growth without the need for a drug compared to the effectiveness when it has a …
Future Of Functional Reactive Programming In Real-Time Systems, Anisha Tasnim
Future Of Functional Reactive Programming In Real-Time Systems, Anisha Tasnim
Theses and Dissertations
The evolution of programming paradigms and the development of new programming languages are driven by the needs of problem domains. Functional reactive programming (FRP) combines functional programming (FP) and reactive programming (RP) concepts that leverage asynchronous dataflow from reactive programming and higher-level abstractions building blocks from functional programming to enable developers to define data flows and transformations declaratively. Declarative programming allows developers to concentrate more on the problem to be solved rather than the implementation details, resulting in efficient and concise code. Over the years, various FRP designs have been proposed in real-time application areas. Still, it remains unclear how …
Hybridity, Ecocriticism, And Feminist Perspectives In She-Ra And The Princesses Of Power, Sarah Warso
Hybridity, Ecocriticism, And Feminist Perspectives In She-Ra And The Princesses Of Power, Sarah Warso
UNLV Theses, Dissertations, Professional Papers, and Capstones
Children’s cartoons are growing increasingly nuanced in the twenty-first century. She-Ra and the Princesses of Power (2018) is an animated television series targeted towards young girls that includes themes of ecocriticism and feminism. The show does this by introducing cyborg, or hybrid, characters. My research explores how cyborg identities in children’s media and their feminist, ecocritical meanings in She-Ra and the Princesses of Power. The cyborg, as a feminist mythic hero, breaks down binaries and recodes communication between opposing forces. The She-Ra is filled with characters that inhabit multiple identities. The main character, Adora, identifies as both a former Evil …

Video Snapshot: Single Image Motion Expansion Via Invertible Motion Embedding, Qianshu Zhu, Chu Han, Guoqiang Han, Tien-Tsin Wong, Shengfeng He
Research Collection School Of Computing and Information Systems
Unlike images, finding the desired video content in a large pool of videos is not easy due to the time cost of loading and watching. Most video streaming and sharing services provide the video preview function for a better browsing experience. In this paper, we aim to generate a video preview from a single image. To this end, we propose two cascaded networks, the motion embedding network and the motion expansion network. The motion embedding network aims to embed the spatio-temporal information into an embedded image, called video snapshot. On the other end, the motion expansion network is proposed to …

Research on creation of virtual humans enables increasing automatization of their behavior, including synthesis of verbal and nonverbal behavior. As the achievable realism of different aspects of agent design evolves asynchronously, it is important to understand if and how divergence in realism between behavioral channels can elicit negative user responses. Specifically, in this work, we investigate the question of whether autonomous virtual agents relying on synthetic text-to-speech voices should portray a corresponding level of realism in the non-verbal channels of motion and visual appearance, or if, alternatively, the best available realism of each channel should be used. In two perceptual …
Invasives In Our National Parks: How Tourists Can Help Stop The Spread Of Invasive Species, Alexandria Elivira Marci
Invasives In Our National Parks: How Tourists Can Help Stop The Spread Of Invasive Species, Alexandria Elivira Marci
Masters Theses
Invasive species are a major issue around the world and more specifically in our U.S. National Parks. Ranging from plants to insects to animals, invasive species are a greater threat than many may imagine. The impact that invasive species have on an ecosystem encompasses more than taking over a native species’ environment; it includes competing for food, water, and other resources, as well as having an adverse effect on our economy and threatening us with deadly diseases. Many factors lead to the cause of spread of invasive species, but all point back to human interference, from purposely spreading invasive species …
Physically Based Rendering Techniques To Visualize Thin-Film Smoothed Particle Hydrodynamics Fluid Simulations, Aditya H. Prasad
Physically Based Rendering Techniques To Visualize Thin-Film Smoothed Particle Hydrodynamics Fluid Simulations, Aditya H. Prasad
Dartmouth College Undergraduate Theses
This thesis introduces a methodology and workflow I developed to visualize smoothed hydrodynamic particle based simulations for the research paper ’Thin-Film Smoothed Particle Hydrodynamics Fluid’ (2021), that I co-authored. I introduce a physically based rendering model which allows point cloud simulation data representing thin film fluids and bubbles to be rendered in a photorealistic manner. This includes simulating the optic phenomenon of thin-film interference and rendering the resulting iridescent patterns. The key to the model lies in the implementation of a physically based surface shader that accounts for the interference of infinitely many internally reflected rays in its bidirectional surface …
Do Animated Line Graphs Increase Risk Inferences?, Junghan Kim, Arun Lakshmanan
Do Animated Line Graphs Increase Risk Inferences?, Junghan Kim, Arun Lakshmanan
Research Collection Lee Kong Chian School Of Business
This article shows that animated display of time-varying data (e.g., stock or commodity prices) enhances risk judgments. We outline a process whereby animated display enhances the visual salience of transitions in a trajectory (i.e., successive changes in data values), which leads to transitions being utilized more to form cognitive inferences about risk. In turn, this leads to inflated risk judgments. The studies reported in this article provide converging evidence via eye tracking (Study 1), serial mediation analyses (Studies 2 and 3), and experimental manipulations of transition salience (graph type; Study 3) and utilization of transitions (global trend; Study 4 and …

Browse all Theses and Dissertations
This thesis research project focuses on design and development of an immersion simulation-based training tool that help raise the social determinants of health (SDOH) awareness among the health care providers. Compared to existing classroom lecture and/or role-play based SDOH education approach, our immersion-simulation based approach provides an easy access and highly realistic experience to such training curriculum at anytime and anywhere with an Internet connection. Such an interactive and immersive exposure is critical to raise SDOH awareness and maintain long-lasting empathy towards actual patients in practice, and thus help providers to be better prepared when encountering with those patients. Particularly, …

A More Accurate Model For Finding Tutorial Segments Explaining Apis, He Jiang, Jingxuan Zhang, Xiaochen Li, Zhilei Ren, David Lo
A More Accurate Model For Finding Tutorial Segments Explaining Apis, He Jiang, Jingxuan Zhang, Xiaochen Li, Zhilei Ren, David Lo
Research Collection School Of Computing and Information Systems
Developers prefer to utilize third-party libraries when they implement some functionalities and Application Programming Interfaces (APIs) are frequently used by them. Facing an unfamiliar API, developers tend to consult tutorials as learning resources. Unfortunately, the segments explaining a specific API scatter across tutorials. Hence, it remains a challenging issue to find the relevant segments. In this study, we propose a more accurate model to find the exact tutorial fragments explaining APIs. This new model consists of a text classifier with domain specific features. More specifically, we discover two important indicators to complement traditional text based features, namely co-occurrence APIs and …
In God’S Land: Cinematic Affect, Animation And The Perceptual Dilemmas Of Slow Violence, Salma Monani
In God’S Land: Cinematic Affect, Animation And The Perceptual Dilemmas Of Slow Violence, Salma Monani
Environmental Studies Faculty Publications
In this paper, I argue that Indian independent filmmaker Pankaj Rishi Kumar's documentary In God’s Land (2012) blends animation and live-action to illuminate the destructive nuances of postcolonial literary scholar, Rob Nixon's notion of slow violence. In turning to cinema, I also suggest that In God’s Land’s “aesthetic strategies” further eco-film scholarship’s recent interests in animation, which have tended to highlight the mode's "feel good affect." I draw attention to In God's Land's hybrid of dark, discordant animation spectacle interspliced in the documentary live-action to articulate the potential of eco-animation outside of this affect. Ultimately, the film not only draws …
A Distributed Map Animation Framework For Spatiotemporal Datasets, Ahmet Sayar
A Distributed Map Animation Framework For Spatiotemporal Datasets, Ahmet Sayar
Turkish Journal of Electrical Engineering and Computer Sciences
Maps are an excellent way to present data that have spatial components. However, when the data being presented vary over time, a simple two-dimensional map ignores an important feature of the data. An animated map that shows a series of two-dimensional maps at successive points in time allows one to add a time dimension to the display of data. The current study proposes a distributed service-oriented architecture to create map animations from spatiotemporal datasets. We extend the open standards GIS web services definitions with a topic-based publish-subscribe paradigm, which best suits the animation requirements. The effectiveness of the technique is …
Java Based Visualization And Animation For Teaching The Dijkstra Shortest Path Algorithm In Transportation Networks, Ivan Makohon, Duc T. Nguyen, Masha Sosonkina, Yuzhong Shen, Manwo Ng
Java Based Visualization And Animation For Teaching The Dijkstra Shortest Path Algorithm In Transportation Networks, Ivan Makohon, Duc T. Nguyen, Masha Sosonkina, Yuzhong Shen, Manwo Ng
Civil & Environmental Engineering Faculty Publications
Shortest path (SP) algorithms, such as the popular Dijkstra algorithm has been considered as the "basic building blocks" for many advanced transportation network models. Dijkstra algorithm will find the shortest time (ST) and the corresponding SP to travel from a source node to a destination node. Applications of SP algorithms include real-time GPS and the Frank-Wolfe network equilibrium.
For transportation engineering students, the Dijkstra algorithm is not easily understood. This paper discusses the design and development of a software that will help the students to fully understand the key components involved in the Dijkstra SP algorithm. The software presents an …

A Representation Of Selected Nonmanual Signals In American Sign Language, Jerry C. Schnepp
A Representation Of Selected Nonmanual Signals In American Sign Language, Jerry C. Schnepp
Jerry C Schnepp
Computer-generated three-dimensional animation holds great promise for synthesizing utterances in American Sign Language (ASL) that are not only grammatical, but believable by members of the Deaf community. Animation poses several challenges stemming from the massive amounts of data necessary to specify the movement of three-dimensional geometry, and there is no current system that facilitates the synthesis of nonmanual signals. However, the linguistics of ASL can aid in surmounting the challenge by providing structure and rules for organizing the data. This work presents a first method for representing ASL linguistic and extralinguistic processes that involve the face. Any such representation must …
Eye-Tracktive: Measuring Attention To Body Parts When Judging Human Emotions, Cathy Ennis, Ludovic Hoyet, Carol O'Sullivan
Eye-Tracktive: Measuring Attention To Body Parts When Judging Human Emotions, Cathy Ennis, Ludovic Hoyet, Carol O'Sullivan
Conference papers
Virtual humans are often endowed with human-like characteristics to make them more appealing and engaging. Motion capture is a reliable way to represent natural motion on such characters, thereby allowing a wide range of animations to be automatically created and replicated. However, interpersonal differences in actors’ performances can be subtle and complex, yet have a strong effect on the human observer. Such effects can be very difficult to express quantitatively or indeed even qualitatively. We investigate two subjective human motion characteristics: attractiveness and distinctiveness. We conduct a perceptual experiment, where participants’ eye movements are tracked while they rate the motions …

K-Sketch: Digital Storytelling With Animation Sketches, Richard Christopher Davis, Nur Camellia Binte Zakaria
K-Sketch: Digital Storytelling With Animation Sketches, Richard Christopher Davis, Nur Camellia Binte Zakaria
Research Collection School Of Computing and Information Systems
K-Sketch gives novice animators an easy way to tell stories with animation sketches. It relies on users’ intuitive sense of space and time, and makes animation easy through the use of sketching and demonstration. Our studies have shown that people take naturally to telling stories with K-Sketch, and it is particularly helpful for exploring the timing of events. We also found that K-Sketch is a good collaborative medium for telling stories. In this demonstration we will show how K-Sketch works and explain how these advantages are realized in practice.
Efficient Control Of Assets In A Modern Production Pipeline, Timothy Curtis
Efficient Control Of Assets In A Modern Production Pipeline, Timothy Curtis
All Theses
Managing large collections of assets created in today's CG productions is no easy task. This thesis examines basic production hierarchies and identifies problems that arise without proper workflow and asset control. The possibility of hundreds of assets being created in several workflows each week creates the potential for extraordinary time waste and user error without a system to track and manage the files being produced. It is becoming increasingly necessary to utilize methods during production that enforce naming and storage standards to prevent catastrophic data loss. This thesis presents an implementation of a customized database used to track all of …

Volumetric Cloud Rendering: An Animation Of Clouds, Zhaoxin Ye
Volumetric Cloud Rendering: An Animation Of Clouds, Zhaoxin Ye
All Theses
This paper demonstrates a production workflow for a volumetric-rendering-based short animation about clouds. The animation is based on the concept of a giant fish swimming in the sky from Zhuangzi's philosophical story. The algorithm and implementation for the modeling and rendering of clouds are also presented. A renderer was developed that uses the OpenVDB library for data storage, fast retrieving and grid manipulation. A user-friendly pipeline was also developed for cloud modeling and rendering, which used Python and XML for adjusting rendering parameters. The pipeline includes Maya to build the rough cloud model and Houdini to calculate the interior light …
Pen-Based Methods For Recognition And Animation Of Handwritten Physics Solutions, Salman Cheema
Pen-Based Methods For Recognition And Animation Of Handwritten Physics Solutions, Salman Cheema
Electronic Theses and Dissertations
There has been considerable interest in constructing pen-based intelligent tutoring systems due to the natural interaction metaphor and low cognitive load afforded by pen-based interaction. We believe that pen-based intelligent tutoring systems can be further enhanced by integrating animation techniques. In this work, we explore methods for recognizing and animating sketched physics diagrams. Our methodologies enable an Intelligent Tutoring System (ITS) to understand the scenario and requirements posed by a given problem statement and to couple this knowledge with a computational model of the student's handwritten solution. These pieces of information are used to construct meaningful animations and feedback mechanisms …
Integrating A Lighting System With Objective Light Movement, Kiel Pease
Integrating A Lighting System With Objective Light Movement, Kiel Pease
All Theses
When applying a light design within computer graphics software, there is no clear-cut way to achieve accurate and noticeable light movement without rigorous work animating the lighting tools by hand. This task can be arduous and involve constant test renders throughout a single frame range. This project strives to explain the production of a short animated feature, by incorporating a video-based lighting system, which is intended to assist with scenes that require objective light movement. The video-based lighting method will strive to minimize (not eliminate) the need to animate by hand light motion from environment lighting. Since lighting design is …
Emotion Capture: Emotionally Expressive Characters For Games, Cathy Ennis, Ludovic Hoyet, Arjan Egges, Rachel Mcdonnell
Emotion Capture: Emotionally Expressive Characters For Games, Cathy Ennis, Ludovic Hoyet, Arjan Egges, Rachel Mcdonnell
Conference papers
It has been shown that humans are sensitive to the portrayal of emotions for virtual characters. However, previous work in this area has often examined this sensitivity using extreme examples of facial or body animation. Less is known about how attuned people are at recognizing emotions as they are expressed during conversational communication. In order to determine whether body or facial motion is a better indicator for emotional expression for game characters, we conduct a perceptual experiment using synchronized full-body and facial motion-capture data. We find that people can recognize emotions from either modality alone, but combining facial and body …
Motion Capture Of Character Interactions With A Rope, Bryce Zachary Porter
Motion Capture Of Character Interactions With A Rope, Bryce Zachary Porter
Theses and Dissertations
We present a solution to animating interactions between characters and thin, non-rigid bodies using a passive optical motion capture system. Prior work in human body motion capture can accurately recreate human motion but this work is not adequate because it does not allow for interactions with a non-rigid body. Prior work in face and cloth motion capture handles non-rigid planes but rope is better handled with a curved spline rather than a curved plane. The segmented motion is in the form of un-indexed motion capture data. After segmenting the motion of the thin, non-rigid body and the human character the …
Impressionist Rendering Of An Animated Painting, Michela Rose
Impressionist Rendering Of An Animated Painting, Michela Rose
All Theses
The following thesis documents the development of a non-traditional rendering technique, that of classic impressionist painting, and its use to create an animated three-dimensional painting. Impressionist style painting has an organic feel to it, with brush strokes that remain visible in the dried paint and a light, lively color palette that seeks to capture the light in an image. Reproducing this style in a computer-generated image is no small task. For this project a CG paint method was developed, utilizing Maya Paint Effects and particles. This method was implemented with a script, saving time by automating the process as much …
