Toward Real-Time Flip Fluid Simulation Through Machine Learning Approximations, Javid Kennon Pack
Toward Real-Time Flip Fluid Simulation Through Machine Learning Approximations, Javid Kennon Pack
Theses and Dissertations
Fluids in computer generated imagery can add an impressive amount of realism to a scene, but are particularly time-consuming to simulate. In an attempt to run fluid simulations in real-time, recent efforts have attempted to simulate fluids by using machine learning techniques to approximate the movement of fluids. We explore utilizing machine learning to simulate fluids while also integrating the Fluid-Implicit-Particle (FLIP) simulation method into machine learning fluid simulation approaches.
Adaptive Fluid Simulation Using A Linear Octree Structure, Sean A. Flynn
Adaptive Fluid Simulation Using A Linear Octree Structure, Sean A. Flynn
Theses and Dissertations
An Eulerian approach to fluid flow provides an efficient, stable paradigm for realistic fluid simulation. However, its traditional reliance on a fixed-resolution grid is not ideal for simulations that simultaneously exhibit both large and small-scale fluid phenomena. Octree-based fluid simulation approaches have provided the needed adaptivity, but the inherent weakness of a pointer-based tree structure has limited their effectiveness. We present a linear octree structure that provides a significant runtime speedup using these octree-based simulation algorithms. As memory prices continue to decline, we leverage additional memory when compared to traditional octree structures to provide this improvement. In addition to reducing …
The Role Of Algorithmic Decision Processes In Decision Automation: Three Case Studies, Blake Edward Durtschi
The Role Of Algorithmic Decision Processes In Decision Automation: Three Case Studies, Blake Edward Durtschi
Theses and Dissertations
This thesis develops a new abstraction for solving problems in decision automation. Decision automation is the process of creating algorithms which use data to make decisions without the need for human intervention. In this abstraction, four key ideas/problems are highlighted which must be considered when solving any decision problem. These four problems are the decision problem, the learning problem, the model reduction problem, and the verification problem. One of the benefits of this abstraction is that a wide range of decision problems from many different areas can be broken down into these four “key” sub-problems. By focusing on these key …
