Bruderlin, Beat | Moving into higher dimensions of geometric constraint solving | In this paper, we present an approach to geometric constraint solving, based on degree of freedom analysis. Any geometric primitive (point, line, circle, plane, etc.) possesses an intrinsic degree of freedom in its embedding space which is usually two or three dimensional. Constraints reduce the deg... | Geometric constraint solving | 1994 |

Carter, John B. | MP-LOCKs: Replacing hardware synchronization primitives with message passing | Shared memory programs guarantee the correctness of concurrent accesses to shared data using interprocessor synchronization operations. The most common synchronization operators are locks, which are traditionally implemented in user-level libraries via a mix of shared memory accesses and hardware sy... | MP-LOCKs; Message passing; Shared memory programs; Synchronization operators; Synchronization primitives | 2011-05 |

Hansen, Charles D. | Multidimensional transfer functions for interactive volume rendering | Abstract-Most direct volume renderings produced today employ one-dimensional transfer functions which assign color and opacity to the volume based solely on the single scalar quantity which comprises the data set. Though they have not received widespread attention, multidimensional transfer function... | 2002-07 | |

Bargteil, Adam Wade | Multiphase flow of immiscible fluids on unstructured moving meshes | In this paper, we present a method for animating multiphase flow of immiscible fluids using unstructured moving meshes. Our underlying discretization is an unstructured tetrahedral mesh, the deformable simplicial complex (DSC), that moves with the flow in a Lagrangian manner. Mesh optimization opera... | 2014-01-01 | |

Venkatasubramanian, Suresh | Multiple target tracking with RF sensor networks | RF sensor networks are wireless networks that can localize and track people (or targets) without needing them to carry or wear any electronic device. They use the change in the received signal strength (RSS) of the links due to the movements of people to infer their locations. In this paper, we cons... | 2014-01-01 | |

Henderson, Thomas C. | Multisensor methods to estimate thermal diffusivity | Several methods for the estimation of thermal diffusivity are studied in this work. In many application scenarios, the thermal diffusivity is unknown and must be estimated in order to perform other estimation functions (e.g., tracking of the physical phenomenon, or solving other inverse problems lik... | 2012-01-01 | |

Shirley, Peter S. | Natural image statistics for computer graphics | The class of all natural images is an infinitely small fraction of all possible images. The structure of natural images can be statistically modeled, revealing striking regularities. The human visual system appears to be optimized to view natural images, as opposed to any possible image, and therefo... | Natural image | 2001 |

Balasubramonian, Rajeev | NDC: Analyzing the impact of 3D-stacked memory+logic devices on MapReduce workloads | While Processing-in-Memory has been investigated for decades, it has not been embraced commercially. A number of emerging technologies have renewed interest in this topic. In particular, the emergence of 3D stacking and the imminent release of Micron's Hybrid Memory Cube device have made it more pra... | 2014-01-01 | |

Shirley, Peter S.; Thompson, William B. | Night rendering | The issues of realistically rendering naturally illuminated scenes at night are examined. This requires accurate models for moonlight, night skylight, and starlight. In addition, several issues in tone reproduction are discussed: eliminatiing high frequency information invisible to scotopic (night v... | Night rendering; Low light -- Computer models | 2000 |

Hibler, Michael J. | Notes on thread models in Mach 3.0 | During the Mach In-Kernel Servers work, we explored two alternate thread models that could be used to support traps to in-kernel servers. In the "migrating threads" model we used, the client's thread temporarily moves into the server's task for the duration of the call.
