NUCLARR and human reliability: data sources and data profile: The Nuclear Computerized Library for Assessing Reactor Reliability (NUCLARR) is an automated database management system used to process, store, and retrieve human and equipment reliability data. Human error rate data are stored and accessed according to the personnel, human actions, and equipment in....; Authors:Gertman;D.I.;Gilmore;W.E.;Ryan;T.G.Publisher:Human Factors and Power Plants;1988.;Conference Record for 1988 IEEE Fourth Conference onConference Date:5-9 June 1988Total Page:xii+596

Operator model-based design evaluation of advanced systems: conceptual models: A multilevel operator modeling approach is recommended to provide broad support for the integrated design of advanced control and protection systems for nuclear power plants. Preliminary design should address the symbiosis of automated systems and human operators by giving careful attention to the r....; Authors:Schryver;J.C.Publisher:Human Factors and Power Plants;1988.;Conference Record for 1988 IEEE Fourth Conference onConference Date:5-9 June 1988Total Page:xii+596

Operator model-based design and evaluation of advanced systems: computational models: A multilevel operator modeling effort is recommended to provide broad support for integrated design of advanced control and protection systems for new nuclear power plants. A computational model called INTEROPS (integrated reactor operator system) is described which accounts for the cognitive activi....; Authors:Schryver;J.C.Publisher:Human Factors and Power Plants;1988.;Conference Record for 1988 IEEE Fourth Conference onConference Date:5-9 June 1988Total Page:xii+596

The experimental evaluation of the success path monitoring system: The success path monitoring system (SPMS) is an advanced computer-based operator aid which is intended to enhance the operator's ability to handle plant disturbances effectively. It achieves this by providing an online assessment of both the status of critical safety functions and the status of appr....; Authors:Marshall;E.C.;Baker;S.M.;Reiersen;C.S.;Owre;F.;Gaudio;P.J.;Jr.Publisher:Human Factors and Power Plants;1988.;Conference Record for 1988 IEEE Fourth Conference onConference Date:5-9 June 1988Total Page:xii+596

Microwave filters based on coupled MSW resonators and their applications: A novel and simple technique for realizing tunable and planar microwave bandpass filters has been investigated. The use of coupled magnetostatic wave (MSW) resonators for realizing these filters is demonstrated. Due to their low magnetic losses, epitaxially grown single-crystal yttrium iron garnet (....; Authors:Hanna;S.M.Publisher:Ultrasonics Symposium;1988.

Torsional mechanical filters at 500 kHz: A torsional mechanical filter configuration has been developed for operation in the commonly used IF (intermediate frequency) range of 500 kHz, utilizing third torsional-mode electromechanical transducer resonators in conjunction with second torsional-mode interior resonators. This structure was der....; Authors:Domino;W.J.Publisher:Ultrasonics Symposium;1988. Proceedings.;IEEE 1988Conference Date:2-5 Oct. 1988Total Page:2 vol. 1113

Ultrasonic motors: An ultrasonic motor is proposed which uses two piezoelectric elements in the stator. One element is used to generate a vibration polarized with respect to the direction of motion of the rotor or the slider. The other one generates a vibration perpendicular to the motion of the rotor. By imaging the ....; Authors:Ueha;S.;Kurosawa;M.Publisher:Ultrasonics Symposium;1988. Proceedings.;IEEE 1988Conference Date:2-5 Oct. 1988Total Page:2 vol. 1113

Online statistical process control with NDE and computers: It is shown that, for statistical process control (SPC) using ultrasonic instruments for nondestructive evaluation (NDE) directly interfaced with a computer, a variable in every part can be measured at production line speeds and used in groups, typically of five, to generate points for control chart....; Authors:Papadakis;E.P.Publisher:Ultrasonics Symposium;1988.

Practical ultrasonic spectrometric measurement of solution concentrations by a tracking technique: The authors designed and tested a practical measurement technique for solutions, based on a resonator with enclosed piezoceramics which can operate at a resonant frequency mode around 500 kHz. The resonance can be tracked automatically by means of a phase-locked loop. The authors report measurements....; Authors:Dion;J.L.;Barwicz;A.;Bouchard;J.Publisher:Ultrasonics Symposium;1988.

Feature extraction and learning decision rules from ultrasonic signals-applicability in non-destructive testing: The author presents a supervised multiple-concept learning method for generating decision rules from a set of ultrasonic data for defect characterization purposes in nondestructive testing. The first step towards flaw discrimination is to extract relevant information from the collected defect signat....; Authors:Perron;M.-C.Publisher:Ultrasonics Symposium;1988.
