Ailion, David Charles | 93Nb NMR in the imcommensurate and quasi-commensurate phases of barium sodium niobate | NMR spectra have been measured for the quadrupole perturbed 1/2 -1/2 transition of 9 3Nb in barium sodium niobate (BSN) between 300 and 650 K. The spectra are inhomogeneously broadened in the incommensurate (/) phase between T7 = 580 K and r c = 540 K as well as in the quasicommensurate (QC) phase ... | NMR; Spectra; Barium sodium niobate; Line shapes | 1994 |

Mecklenburg, Robert | A dossier driven persistent objects facility | We describe the design and implementation of a persistent object storage facility based on a dossier driven approach. Objects are characterized by dossiers which describe both their language defined and "extra-linguistic" properties. These dossiers are generated by a C+-f- preprocessor in concert ... | Persistent object storage facility; Dossier driven | 1994 |

Sobh, Tarek M. | A graphical environment and applications for discrete event and hybrid systems in robotics and automation | In this paper we present an overview for the development of a graphical environment for simulating, analyzing, synthesizing, monitoring, and controlling complex discrete event and hybrid systems within the robotics, automation, and intelligent system domain. We start by presenting an overview of di... | Intelligent system domain; Graphical environment | 1994 |

Weinstein, David | A morphing algorithm for generating near optimal grids: applications in computational medicine | We apply morphing to t h e problem of generating the initial mesh for finite element simulations. This algorithm reduces mesh adaptation time by integrating physical and geometric constraints to provide a near optimal initial mesh. We apply this method to large-scale bioelectric field problems invol... | Morphing algorithm; Bioelectric field problems | 1994 |

Bruderlin, Beat | A new approach to tolerance analysis | Tolerance analysis is seen as part of a more general problem, namely handling data with uncertainty. Uncertain geometric data arises when interpreting measured data, but also in solid modeling where floating point approximations are common, when representing design tolerances, or when dealing with l... | Tolerance analysis | 1994 |

Furse, Cynthia M.; Gandhi, Om P. | A simple convolution procedure for calculating currents induced in the human body for exposure to electromagnetic pulses | Abstract-The finite-difference time-domain (FDTD) and frequency dependent finite difference time-domain (FD)2TD methods have been previously used to calculate internal electric (E) fields and induced currents for exposure of the anatomically based model of the human body to electromagnetic pulses (E... | 1994 | |

Mathews, V. John | A stability condition for certain bilinear systems | Abstract-This correspondence derives a simple sufficient condition for the output of a discrete-time, time-invariant bilinear system to be bounded whenever the input signal to the system is bounded by a finite constant. | 1994 | |

Mathews, V. John | A stability result for RLS adaptive bilinear filters | Abstract- This letter considers recursive least squares (RLS) adaptive nonlinear filtering using bilinear system models. It is shown that the extended RLS adaptive bilinear filter, as well as the equation-error RLS adaptive bilinear filter, are guaranteed to be stable in the sense that the time aver... | 1994 | |

Sobh, Tarek M.; Henderson, Thomas C. | A unifying framework for tolerance analysis in sensing, design, and manufacturing | In this work we address the problem of tolerance representation and analysis across the domains of industrial inspection using sensed data, CAD design, and manufacturing. Instead of using geometric primitives in CAD models to define and represent tolerances, we propose the use of stronger methods t... | Tolerance representation; Tolerance analysis; Industrial inspection; Sensed data; CAD design | 1994 |

Ogburn, Joyce L. | Acquiring minds want to know: smart systems, smart books | This article will outline a specific suggestion both to aid some basic acquisitions functions and their management. It will focus primarily on use of vendors, vendor performance and business terms. I have several suggestions for improvement, which were touched on briefly in the first article, based... | Libraries; Acquisitions; Vendors | 1994 |

Mathews, V. John | Adaptive bilinear predictors | This paper considers an extended recursive least squares (RLS) adaptive bilinear predictor. It is shown that the extended RLS adaptive bilinear predictor is guaranteed to be stable in the sense that the time average of the squared a-posteriori prediction error signal is bounded whenever the input... | 1994 | |

Bruderlin, Beat | An interactive N-Dimensional constraint system | In this paper, we present a graph-based approach to geometric constraint solving. Geometric primitives (points, lines, circles, planes, etc.) possess intrinsic degrees of freedom in their embedding space. Constraints reduce the degrees of freedom of a set of objects. A constraint graph is created wi... | Geometric constraint solving | 1994 |

Flynn, John J. | Antitrust policy and health care reform | Among the economic and political challenges facing the United States today, none is more significant - yet difficult to resolve - than the complex puzzle of how to reform the delivery of health care services. A consensus appears to have been reached that reform should extend health care coverage to ... | 1994 | |
