  • Painterly rendering using space-time varying style parameters

    Creator:
    Kagaya, Mizuki
    Abstract:
    Automatic painterly rendering systems have been proposed but they opted for selecting a single style to generate paintings from images, which lacks the ability of creatively using multiple styles to focus important objects and deemphasize unimportant part of the scenes. We provide a multi-style painting framework to address this issue...

    Creator:
    Chen, Guoning, Mischaikow, Konstantin Michael, Laramee, Robert S., Pilarczyk, Pawel, Zhang, Eugene, and Oregon State University. School of Electrical Engineering and Computer Science
    Abstract:
    Design and control of vector fields is critical for many visualization and graphics tasks such as vector field visualization, fluid simulation, and texture synthesis. The fundamental qualitative structures associated with vector fields are fixed points, periodic orbits, and separatrices. In this paper we provide a new technique that allows for...

  • A recurrent neural network implementation using the graphics processing unit

    Creator:
    Moore, Christopher
    Abstract:
    We took the back-propagation algorithms of Werbos for recurrent and feed-forward neural networks and implemented them on machines with graphics processing units (GPU). The parallelism of these units gave our implementations a 10 to 100 fold increase in speed. For nets with less than 20 neurons the machine performed faster...

  • Topological analysis, visualization, and design of vector fields on surfaces

    Creator:
    Chen, Guoning
    Abstract:
    Analysis, visualization, and design of vector fields on surfaces have a wide variety of major applications in both scientific visualization and computer graphics. On the one hand, analysis and visualization of vector fields provide critical insights to the flow data produced from simulation or experiments of various engineering processes. On...

  • OP-AMP free SC biquad LPF and delta-sigma ADC

    Creator:
    Yoo, Kiseok
    Abstract:
    The objective of this work is to explore the feasibility of replacing conventional op-amps with inverters in switched-capacitor (SC) circuits. In order to verify the idea, a low-pass filter (LPF) and a second-order delta-sigma (∆Σ) analog-todigital converter (ADC) are designed in the 0.5-m CMOS technology. The low-pass filter structure is...

  • Student understanding of functions and the use of the graphing calculator in a college algebra course

    Creator:
    Averbeck, Patrick J.
    Abstract:
    The purpose of the study was to investigate students' learning of the function concept and the role of the graphing calculator in a College Algebra course. Differences between students with high symbolic manipulation skills. and students with low symbolic manipulation skills were also examined. On the basis of an algebraic...

  • Graphical models for multivariate spatial data

    Creator:
    Irvine, Kathryn M.
    Abstract:
    In this thesis we focus on a graphical model for multivariate spatially correlated data--isomorphic chain graphs (ICG; Gitelman and Herlihy, 2007). We feel ICG allow flexibility for modeling spatial correlation and are intuitively appealing because each model has an associated graph that visually represents a complex multivariate system. We examine...

  • How to Render Mathematical Symbols in Java

    Creator:
    Sun, Yuemei
    Abstract:
    Current math software provides limited interactivity and dynamics when conveying math ideas. We are developing prototype Java toolkits to display math-embedded documents in a more dynamic and interactive way. The core task of current project is to create a Java implementation of a MathML (in which a math expression is...
