Miller, Joel Steven; Epstein, Arthur J. | Organic and molecular ferromagnets | Unlike common ferromagnets such as iron, nickel, cobalt or even cobalt-samarium and Nb-Fe-B, it is extremely rare for a discrete molecule, especially an organic or polymeric material, to have cooperative magnetic interactions. Since the mid-1980s a few such materials have been prepared which demon... | Magnetic; Magnetization; Temperature | 1992 |

Morse, Michael David | Spectrosopic studies of jet-cooled NiAu and PtCu | Spectroscopic investigations of NiAu and PtCu have revealed that both molecules possess 2?5/2 ground electronic states, and are in this respect analogous to the isovalent molecule NiCu. The ground-state bond lengths (r?) have been measured as 2.351?0.001 ? and 2.335?0.001 ? for NiAu and PtCu, respe... | | 1992 |

Morse, Michael David | Predissociation lifetimes of vibrational levels of the excited ? B? (Ka=O) electronic states of Cd ? H? and Cd ? D? complexes | The experimental rates of predissociation of vibrational levels of the ?B? (K'a-O) excited states of the Cd ? HZ and Cd ? D2 complexes are shown to be consistent with both semiclassical and quantum-mechanical pseudodiatomic theoretical treatments of the process. The ?B? pseudodiatomic potential was ... | | 1992 |

Sobh, Tarek M.; Henderson, Thomas C. | A dynamic framwork for intelligent inspection | CAD Computer Aided Design typically involves the design manufacture and inspection of a me chanical part. The problem of reverse engineering is to take an existing mechanical part as the point of departure and to inspect or produce a design and perhaps a manufacturing process for the part. ... | CAD; Manufacture; Inspection; Intelligent inspection | 1992 |

Ailion, David Charles | Thermal fluctuations and NMR spectra of incommensurate systems | In the presence of thermal fluctuations the incommensurate NMR line shape is a convolution of a static inhomogeneous with a dynamic homogeneous line shape which can be determined separately by 2D NMR. The form of the dynamic line shape and its variation over the inhomogeneous NMR spectrum permit a ... | Thermal fluctuations; NMR; Incommensurate systems; Line shape | 1992 |

Adler, Frederick R. | Information collection and spread by networks of patrolling ants | To study how a social group, such as an ant colony, monitors events occurring throughout its territory, we present a model of a network of patrolling ants engaged in information collection and dissemination. In this network, individuals follow independent paths through a region and can exchange sign... | Patrolling network; ant colony; information-gathering | 1992 |

Kessler, Robert R. | Using utilization profiles in allocation and partitioning for multiprocessor systems | The problems of multiprocessor partitioning and program allocation are interdependent and critical to the performance of multiprocessor systems. Minimizing resource partitions for parallel programs on partitionable multiprocessors facilitates greater processor utilization and throughput. The proces... | utilization profiles; multiprocessor partitioning; program allocation | 1992 |

Mathews, V. John | Multiplication free vector quantization using the L 1 distortion measure and its variants | Vector quantization is a very powerful technique for data compression and consequently, it has attracted a lot for attention lately. One major drawback associated with this approach is its extreme computational complexity. This paper fist considers vector quantization that uses the L1 distortion mea... | | 1992 |

| The programming language jigsaw: mixins, modularity and multiple in heritance | This dissertation provides a framework for modularity in programming languages. In this framework known as Jigsaw, inheritance is understood to be an essential linguistic mechanism for module manipulation. In Jigsaw, the roles of classes in existing languages are "unbundled," by providing a suit... | Jigsaw framework; Mixins | 1992 |

McDaniel, Susan | Women and family in the later years: findings from the 1990 general social survey | Aging is a feminist issue. Women on average live longer than men, live longer in disability or with chronic health problems, more often experience the deaths of spouse and friends, more often live alone in their later years, are significantly poorer than men of the same age, and more often institu... | Middle age; Old age; Family life; Women | 1992 |

Myers, Chris J. | Direct synthesis of timed asynchronous circuits | This paper presents a new method to synthesize timed asynchronous circuits directly from the specification without generating a state graph. Our synthesis procedure begins with a deterministic signal transition graph specification to which timing constraints can be added. First, a timing analysis ex... | | 1992 |

Cohen, Elaine | Second order surface analysis using hybrid symbolic and numeric operators | Results from analyzing the curvature of a surface can be used to improve the implementation, efficiency, and effectiveness of manufacturing and visualization of sculptured surfaces. In this paper, we develop a robust method using hybrid symbolic and numeric operators to create trimmed surfaces each... | Surface analysis; Hybrid symbolic operators; Numeric operators | 1992 |

Silverman, Randall H. | Pamphlet binders and their use in research libraries | By definition, research libraries have a commitment to preserving pamphlets as well as all print and non-print media they collect. A discussion of the preservation requirements for pamphlets is useful for their survival, and pamphlet binders are an important tool in preparing these often ephemeral ... | Pamphlets; Preservation; Binders | 1992 |

Bruderlin, Beat | Robust boolean set operations for manifold solids bounded by planar and natural quadric surfaces | This paper describes our latest effort in robust solid modeling. An algorithm for set operations on solids bounded by planar and natural quadric surfaces, that handles all geometrically degenerate cases robustly, is described. We identify as the main reason for the lack of robustness in geometric m... | Robust solid modeling; Robust boolean set operations; Manifold solids | 1992 |

Couldwell, William T. | Malignant glioma-derived soluble factors regulate proliferation of normal adult human astrocytes | Malignant gliomas are characteristically surrounded by marked gliosis. To assess whether glioma-derived products contribute to the proliferation of astrocytes, a feature of the gliosis response, we evaluated the influence of culture supernatants from malignant human glioma lines and tumor cyst fluid... | Astrocyte; Glioma; Gliosis; Proliferation; Soluble factors | 1992 |

Gopalakrishnan, Ganesh | Dynamic reordering of high latency transactions in time-warp simulation using a modified micropipeline | Time warp based simulation of discrete-event systems is an efficient way to overcome the synchronization overhead during distributed simulation. As computations may proceed beyond synchronization barriers in time warp, multiple checkpoints of state need to be maintained to be able to rollback inva... | Asynchronous design; Micropipelines; Dynamic instruction reordering; Time warp simulations | 1992 |

Christensen, Douglas A. | Laser diode coherence length variation with drive current: a tool for dispersion measurements | A visible light (670nm) laser diode was used as a variable coherence length source to measure dispersion characteristics in single-mode fibers. The diode's spectral width, measured against increasing drive current, was found to change from about 16 nanometers to less than 0.2 nanometer. The corresp... | Laser diode; Fiber interferometry | 1992 |

Davidson, Diane W. | Experimental manipulation of food bodies in Cecropia | Neotropical Cecropia trees range from Mexico to Argentina and are typical of disturbed habitats. Cecropia plants provide food and housing for the ants in return for known or presumed protection from herbivores and vine cover. Glycogen-rich Mullerian bodies (MB's) are the predominant food source for ... | Mullerian bodies; Trichilia; Cecropia tessmannii; Cecropia pungara | 1992 |

Olivera, Baldomero M. | Conus peptides: phylogenetic range of biological activity | The major function of the venoms of the predatory marine snails belonging to the genus Conus is to paralyze prey. Thus, the venom of each Conus species acts on receptors and ion channels of the prey; previous studies suggested much less activity on homologous receptor targets in more distant taxa.... | Conus peptides; Conopeptides; Conotoxins | 1992 |

Landesman, Bruce M. | Health care in a national health program: a fundamental right | Do or should Americans have a right to health care or some appropriate level of it?
