Miller, Jan D. | A new cone beam X-ray microtomography facility for 3D analysis of multiphase materials | Three-dimensional x-ray microtomography offers a unique imaging capability. Spatial resolution on the order of ten microns can be achieved with the use of microfocus x-ray generators. Recently, a state-of-the-art, flexible cone beam x-ray microtomography system has been installed at the University o... | 2001-01-01 | |

Regehr, John | Augmented CPU reservations: towards predictable execution on general-purpose operating systems | One problem with performing soft real-time computations on general-purpose operating systems is that these OSs may spend significant amounts of time in the kernel instead of performing work on behalf of the application that is nominally scheduled: the OS effectively steals time from the running appl... | 2001-01-01 | |

Furse, Cynthia M.; Cherkaev, Elena A. | Cross-borehole delineation of a conductive ore deposit in a resistive host-experimental design | The finite-difference time-domain method is used for high-resolution full-wave analysis of cross-borehole electromagnetic surveys of buried nickel sulfide deposits. The method is validated against analytical methods for simple cases, but is shown to be a valuable tool for analysis of complicated ... | Finite-difference time-domain; FDTD; Cross-borehole; Electromagnetic surveys; Nickel sulfide deposits; Conductive ores; Resistive host | 2001-01-01 |

Furse, Cynthia M. | Down to the wire | As today's military and commercial aircraft age past their teen years, the many kilometers of wiring buried deep within their structures begin to crack and fray. Once thought to be rare and benign, such faults are found by the hundreds in a typical aircraft. Unlike obvious cracks in a wing or an e... | Aging wiring; Wire fault location; Aging wire detection; Smart wire systems | 2001-01-01 |

Regehr, John | HLS: a framework for composing soft real-time schedulers | Hierarchical CPU scheduling has emerged as a way to (1) support applications with diverse scheduling requirements in open systems, and (2) provide load isolation between applications, users, and other resource principals. Most existing work on hierarchical scheduling has focused on systems that prov... | 2001-01-01 | |

Barusch, Amanda | Social security is not for babies: trends and policies affecting older women in the United States | In the first year of the new century, over a million American women officially entered the ranks of "the elderly" by reaching their 65th birthday (U.S. Bureau of the Census, 1999). What can they expect of government policy? To what extent will the nation's economic support systems respond to their n... | Income security; Shifting fertility patterns; Labor force participation | 2001-01-01 |

Regehr, John | Some guidelines for proportional share CPU scheduling in general-purpose operating systems | Our premise is that since there already exists a large, mature body of literature on real-time scheduling in general-purpose operating systems, it is time to spend more effort deciding which of these algorithms should be used and when, and less effort on generating new algorithms. In this paper we f... | 2001-01-01 | |

Gerig, Guido | Tumor-induced structural radiometric asymmetry in brain images | This paper presents a general framework for analyzing structural and radiometric asymmetry in brain images. In a healthy brain, the left and right hemispheres are largely symmetric across the mid-sagittal plane. Brain tumors may belong to one or both of the following categories: mass-effect, in whic... | 2001-01-01 | |

Regehr, John | Two case studies in predictable application scheduling using Rialto/NT | This paper analyzes the results of two case studies in applying the Rialto/NT scheduler to real Windows 2000 applications. The first study is of a soft modem-a modem whose signal processing work is performed on the host CPU, rather than on a dedicated signal processing chip. The second is of an audi... | 2001-01-01 | |

Regehr, John | Using hierarchical scheduling to support soft real-time applications in general-purpose operating systems | The CPU schedulers in general-purpose operating systems are designed to provide fast response time for interactive applications and high throughput for batch applications. The heuristics used to achieve these goals do not lend themselves to scheduling real-time applications, nor do they meet other s... | 2001-01-01 | |
