Christensen, Douglas A.; Vincent, G. Michael | Fiberoptic laser angioplasty probe with optical steerability | We have designed and bench tested an optically steerable fiberoptic probe for use in laser angioplasty. The unique feature of this design is the use of a gradient-index (GRIN) lens attached to the distal end of a seven-fiber bundle. By selecting which fiber of the bundle is illuminated by the source... | Fiberoptic probe; GRIN lens; Steerability | 1990 |

Michell, Nick | On the potential of asynchronous pipelined processors | An asynchronous version of the pipelined R3000 and DLX processors, the A3000, is being designed. Simulation was employed t o investigate the potential speed-up obtainable due t o the asynchronous operation. Preliminary results show up to a 64% improvement in performance. | Pipelined processors; Pipelined R3000; DLX processors; A3000 | 1990 |

Henderson, Thomas C. | Zo: A framework for autonomous agent behavior specification and analysis | We describe a framework for the specification and analysis of autonomous agents1 . In general, such agents require several levels of behavioral specifications, including: low-level reflex actions, mid-level controllers to deal with the physical aspects of the world, and highlevel representations for... | Z-Infinity; Autonomous agents; Behavior | 1990 |

Mathews, V. John | Tracking analysis of the sign algorithm in nonstationary environments | This paper presents a tracking analysis of the adaptive filters equipped with the sign algorithm and operating in nonstationary environments. Under the assumption that the nonstationarity can be modeled using a random disturbance, it is shown that the long-term time average of the mean-absolute erro... | 1990 | |

Miller, Jan D. | Spectroscopic analysis of passivation reactions for carbonaceous matter from carlin trend ores | Abstract. Three different refractory carbonaceous gold ores from the Carlin operation in northeastern Nevada were investigated to characterize the effect of passivation treatments on the nature of the carbonaceous material. The carbonaceous material was chemically isolated from the ores and pass... | Gold; Chlorine; Cyanidation | 1990 |

Vardeny, Zeev Valentine | Ultrafast electronic and acoustic effects in conducting polymers | The polarized picosecond pump and probe technique with 50 fsec resolution has been used to generate and detect electronic excitations and propagation of ultrasonic phonons in thin films of oriented and unoriented polyacetylene and polythiophene. We found that the photoexcitations are instantaneou... | Ultrafast electronic effects; Ultrafast acoustic effects; Polarized picosecond pump; Pump and probe technique; Ultrasonic phonons | 1990 |

George, Lal | A scheduling strategy for shared memory multiprocessors | An efficient scheduling strategy for shared memory multiprocessors is described. The rapid dissemination of tasks to available procesors and ready queues is crucial to the performance of any parallel system. Such overheads determine the attainable speedup and performance of the system. Poor techniq... | Shared memory multiprocessors | 1990 |

Battin, Margaret P. | Seven caveats concerning the discussion of euthanasia in Holland | As the discussion of voluntary active euthanasia heats up in the United States (indeed, I believe it will be the major social issue of the next decade, replacing abortion in that role), increasing attention is being given to its practice in the Netherlands. Proponents of the view that the United Sta... | 1990 | |

Horch, Kenneth W.; Normann, Richard A. | Simulation of a phosphene field based visual prosthesis | A visual prosthesis for the blind based upon electrical stimulation of the visual cortex requires the development of an array of electrodes. To establish design specifications for such an electrode array, we have conducted psychophysical experiments with normally sighted subjects wearing a portable... | Visual prosthesis; Phosphene simulator | 1990 |

Normann, Richard A.; Chandler, John P. | Effects of calcium ions on L-type horizontal cells in the isolated turtle retina | A technique by which the retina can be isolated from the turtle eye is described. Scanning electron microscopy revealed morphological variability between preparations and also between regions of the same one. Large areas were often totally free of any pigment epithelial cells, yet contained a high p... | Retina; Calcium; Horizontal Cell; Turtle | 1990 |
