Line Sampling In Participating Media, Hsu Cheng 2021 Dartmouth College

Line Sampling In Participating Media, Hsu Cheng

Dartmouth College Master’s Theses and Essays

Participating media, such as fog, fire, dust, and smoke, surrounds us in our daily life. Rendering participating media efficiently has always been a challenging task in physically based rendering. Line sampling has been derived to be an alternative method in direct lighting recently. Since line sampling takes visibility into account, it could reduce variance in the same render time compared to point sampling. We leverage the benefits of line sampling in the context of evaluating direct lighting in participating media. We express the direct lighting as a three-dimensional integral and perform line sampling in any one of them. We show ...


Exploring The Relationship Between Intrinsic Motivation And Receptivity To Mhealth Interventions, Sarah Hong 2021 Dartmouth College

Exploring The Relationship Between Intrinsic Motivation And Receptivity To Mhealth Interventions, Sarah Hong

Dartmouth College Undergraduate Theses

Recent research in mHealth has shown the promise of Just-in-Time Adaptive Interventions (JITAIs). JITAIs aim to deliver the right type and amount of support at the right time. Choosing the right delivery time involves determining a user's state of receptivity, that is, the degree to which a user is willing to accept, process, and use the intervention provided.

Although past work on generic phone notifications has found evidence that users are more likely to respond to notifications with content they view as useful, there is no existing research on whether users' intrinsic motivation for the underlying topic of mHealth ...

City Goers: An Exploration Into Creating Seemingly Intelligent A.I. Systems, Matthew Brooke 2021 University of Arkansas, Fayetteville

City Goers: An Exploration Into Creating Seemingly Intelligent A.I. Systems, Matthew Brooke

Computer Science and Computer Engineering Undergraduate Honors Theses

Artificial Intelligence systems have come a long way over the years. One particular application of A.I. is its incorporation in video games. A key goal of creating an A.I. system in a video game is to convey a level of intellect to the player. During playtests for Halo: Combat Evolved, the developers at Bungie noticed that players deemed tougher enemies as more intelligent than weaker ones, despite the fact that there were no differences in behavior in the enemies. The tougher enemies provided a greater illusion of intelligence to the players. Inspired by this, I set out to ...

Achieving Differential Privacy And Fairness In Machine Learning, Depeng Xu 2021 University of Arkansas, Fayetteville

Achieving Differential Privacy And Fairness In Machine Learning, Depeng Xu

Theses and Dissertations

Machine learning algorithms are used to make decisions in various applications, such as recruiting, lending and policing. These algorithms rely on large amounts of sensitive individual information to work properly. Hence, there are sociological concerns about machine learning algorithms on matters like privacy and fairness. Currently, many studies only focus on protecting individual privacy or ensuring fairness of algorithms separately without taking consideration of their connection. However, there are new challenges arising in privacy preserving and fairness-aware machine learning. On one hand, there is fairness within the private model, i.e., how to meet both privacy and fairness requirements simultaneously ...

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Effective facilitation of active learning is key to enhancing student engagement in engineering classrooms. Instructors need opportunities for frequent observation, feedback, and reflection on the use of their active learning strategies, yet there are no validated automated approaches available. We address this need by designing a feedback dashboard, TEACHActive, that leverages classroom analytics from an automated sensing observation system. The TEACHActive dashboard provides feedback on the in-class implementation of various active learning strategies in engineering classrooms. In this poster, we present the initial phases of a human-centered dashboard design process. The human-centered design (HCD) approach includes techniques such as, creating ...

A Composite Framework Of Co-Located Asymmetric Virtual Reality, Kaitlyn M. Ouverson, Stephen B. Gilbert

Industrial and Manufacturing Systems Engineering Publications

As the variety of possible interactions with virtual reality (VR) continues to expand, researchers need a way to relate these interactions to users' needs and goals in ways that advance understanding. Existing efforts have focused mainly on the symmetric use of technology, which excludes a rising form of interaction known as asymmetric VR, in which co-located participants use different interfaces to interact with a shared environment. There must be a clear path to creating asymmetric VR systems that are rooted in previous work from several fields, as these systems have use cases in education, hybrid reality teams (using VR and ...


Recent Advances In Smartphone Computational Photography, Paul Friederichsen 2021 University of Minnesota - Morris

Recent Advances In Smartphone Computational Photography, Paul Friederichsen

Scholarly Horizons: University of Minnesota, Morris Undergraduate Journal

Smartphone cameras present many challenges, most of which come from the need for them to be physically small. Their small size puts a fundamental limit on their ability to resolve detail and collect light, which makes low-light photography and zooming difficult. This paper presents two approaches to improve smartphone photography through software techniques. The first is handheld super-resolution which uses natural hand movement to improve the resolution smartphone images, especially when zoomed. The second approach is a system which improves low light photography in smartphones.


Physics Engine On The Gpu With Opengl Compute Shaders, Quan Huy Minh Bui 2021 Cal Poly

Physics Engine On The Gpu With Opengl Compute Shaders, Quan Huy Minh Bui

Master's Theses

Any kind of graphics simulation can be thought of like a fancy flipbook. This notion is, of course, nothing new. For instance, in a game, the central computing unit (CPU) needs to process frame by frame, figuring out what is happening, and then finally issues draw calls to the graphics processing unit (GPU) to render the frame and display it onto the monitor. Traditionally, the CPU has to process a lot of things: from the creation of the window environment for the processed frames to be displayed, handling game logic, processing artificial intelligence (AI) for non-player characters (NPC), to the ...

Gpu High-Performance Framework For Pic-Like Simulation Methods Using The Vulkan® Explicit Api, Kolton Jacob Yager

Master's Theses

Within computational continuum mechanics there exists a large category of simulation methods which operate by tracking Lagrangian particles over an Eulerian background grid. These Lagrangian/Eulerian hybrid methods, descendants of the Particle-In-Cell method (PIC), have proven highly effective at simulating a broad range of materials and mechanics including fluids, solids, granular materials, and plasma. These methods remain an area of active research after several decades, and their applications can be found across scientific, engineering, and entertainment disciplines.

This thesis presents a GPU driven PIC-like simulation framework created using the Vulkan® API. Vulkan is a cross-platform and open-standard explicit API for ...


Google Books, Jody Condit Fagan 2021 James Madison University

Google Books, Jody Condit Fagan

Libraries

Google Books’ (GB) full-text search of more than 40 million books offers significant value for libraries and their patrons. However, Google’s refusal to disclose information about the coverage of GB, as well as observed gaps and inaccuracies in the collection and its metadata, makes it difficult to recommend with confidence for a given research need. While most search and retrieval functions work well, glitches aren’t hard to find, which suggests GB development is focused on user experiences that relate to monetization. Privacy and equity concerns surrounding GB mirror those of other big technology platforms. Still, every librarian should ...
