Henderson, Thomas C. | The synthesis of visual recognition strategies | A coherent automated manufacturing system needs to include CAD/CAM, computer vision, and object manipulation. Currently, most systems which support CAD/CAM do not provide for vision or manipulation and similarly, vision and manipulation systems incorporate no explicit relation to CAD/ CAM models. CA... | visual recognition; automated manufacturing systems; object manipulation | 1985 |

Barsky, Brian A. | A description of several tools for the synchronization of concurrent processes | Concurrent processes are tasks which may be executed simultaneously. When several such processes have access to shared variables, it is necessary to establish some regimen to control this access. Several language tools for expressing various synchronization disciplines are presented. | Concurrent processes | 1980 |

Smith, Kent F. | A fast parallel squarer based on divide-and-conquer | Fast and small squarers are needed in many applications such as image compression. A new family of high performance parallel squarers based on the divide-and-conquer method is reported.

Cohen, Elaine | A hole-filling algorithm for triangular meshes | Data obtained by scanning 3D models typically contains missing pieces and holes. These can be caused due to scanning artifacts or artifacts in the surface due to wear and tear. We provide a method based on the Moving Least Squares projection to fill holes in triangular meshes obtained during the ... | Hole-filling algorithm; Triangular meshes; 3D models; Scanning | 2004-12-20 |

Henderson, Thomas C. | Evolutionary teleomorphology | The physical layout of organs and neural structures in biological systems is important to their functioning, and is the result of evolutionary selection forces. We believe this is true even at the individual neuron level, and should be accounted for in any bio-based approach. In particular, when tr... | Evolutionary teleomorphology; Bio-based approach; Physical layout problem; PLP; Neurons; Nodes | 1995 |

Smits, Brian | Global illumination test scenes | The global illumination community has discussed having a database of scenes that could be used to compare and validate different global illumination algorithms. We present a set of test scenes for global illumination algorithms and propose that they be the beginning of such a database. These scenes ... | Global illumination | 2000 |

Henderson, Thomas C. | The importance of unknows in Epidemiologic studies | 1. Epidemiologic study data often include omitted/unobtainable responses (unknowns). In most cases, unknowns are eliminated during data-reduction to facilitate analysis. We examined the effect that elimination of unknowns would have on mortality calculations using data on newborns admitted to a newb... | Unknowns; Mortality calculations | 1985 |

Weinstein, David | Localization of multiple deep epileptic sources in a realistic head model via independent component analysis | Estimating the location and distribution of current sources within the brain from electroencephalographic (EEG) recordings is an ill-posed inverse problem. The ill-posedness of the problem is due to a lack of uniqueness in the solution; that is, different configurations of sources can generate ident... | EEG; Current sources; Head model | 2000 |

Johnson, Christopher R. | Map3d: scientific visualization program for multichannel time series data on unstructured, three-dimensional meshes. program user's guide | There are many examples in biomedical research of recording time signals with multi-sensor arrays whose elements are arranged in irregular, three-dimensional grids [1, 2, 3, 4]. If the nodes in such arrays can be connected into "surfaces", it is possible to employ linear interpolation techniques to ... | Map3D; Multi-sensor arrays; Scientific visualization; Multichannel time series data; Three-dimensional meshes | 1994 |

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.
