Sikorski, Kris | An interior ellipsoid algorithm for fixed points | We consider the problem of approximating fixed points of non-smooth contractive functions with using of the absolute error criterion. In [12] we proved that the upper bound on the number of function evaluations to compute ?-approximations is 0(n3(In 1/? + In 1/1-q +In n)) in the worst case, where ... | Ellipsoid algorithm; Contractive functions; Fixed points | 1998 |

Boll, Steven F. | Application of the saber method for improved spectral analysis of noisy speech | A stand alone noise suppression algorithm is described for reducing the spectral effects of acoustically added noise in speech. A fundamental result is developed which shows that the spectral magnitude of speech plus noise can be effectively approximated as the sum of magnitudes of speech and noise.... | Noise suppression algorithm; SABER method | 1977 |

Tasdizen, Tolga; Whitaker, Ross T. | Cramer-Rao bounds for nonparametric surface reconstruction from range data | The Cramer-Rao error bound provides a fundamental limit on the expected performance of a statistical estimator. The error bound depends on the general properties of the system, but not on the specific properties of the estimator or the solution. The Cramer-Rao error bound has been applied to scal... | Cramer-Rao bounds; Error bounds; 3D reconstruction | 2003-04-18 |

Henderson, Thomas C. | Implementing multi-sensor systems in a functional language | We discuss a methodology for configuring systems of sensors using a functional language. To date no such general methodology exists, and existing multi-sensor systems have been hand-crafted around a particular application. Our main point is that the use of abstraction and of functional language fe... | Multi-sensor systems; Multisensor systems | 1984 |

Lindstrom, Gary E. | The key node method: a highly-parallel alpha-beta algorithm | A new parallel formulation of the alpha-beta algorithm for minimax game tree searching is presented. Its chief characteristic is incremental information sharing among subsearch processes in the form of "provisional" node value communication. Such "eager" communication can offer the double benefit of... | Key node method; Alpha-beta algorithm; Minimax; Game tree searching | 1983 |

Weinstein, David | Lead field basis for FEM source localization | In recent years, significant progress has been made in the area of EEG/MEG source imaging. source imaging on simple spherical models has become increasingly efficient, with consistently reported accuracy of within 5mm. In contrast, source localization on realistic head models remains slow, with sub-... | FEM source localization; Source imaging; EEG; MEG | 1999 |

Keller, Robert M. | An approach to determinacy proofs | It is known that any parallel program graph composed of continuous operators itself represents a continuous function. In other words, the network is determinate in the sense that for a given input, the output is unique, independent of the timing of the constituent operators.
