Video storyboards: summarising video sequences for indexing and searching of video databases: Ongoing research into intelligent image databases continues to produce new and innovative techniques for the browsing and retrieval of digital images, but these techniques are generally not applicable to moving image (video) databases. Video sequences, by their very nature, contain a temporal element. This, coupled with the high volume of data need....; Authors:Macer;P.J.;Thomas;P.J.Publisher:Intelligent Image Databases;IEE Colloquium onConference Date:ISSN:Total Page:86

Electromagnetic simulator interfacing to a general CAD framework: automatic, electromagnetic-based mesh generation: An electromagnetic simulator has been interfaced through a custom-meshing program to a general CAD (computer-aided design) framework. Standard information within the CAD framework (netlist information, location in layout, and maximum simulation frequency) is all that is needed to automatically generate a surface mesh (consisting of triangles and re....; Authors:Draxler;P.J.Publisher:Microwave Symposium Digest;1993.;IEEE MTT-S InternationalConference Date:14-18 June 1993ISSN:0-7803-1209-0Total Page:3 vol.

Effective waveform recorder evaluation procedures: The author describes a waveform-recorder evaluation system which is controlled by a Microvax II with instrumentation control through the IEEE-488 bus. Evaluation procedures are described with attention to the 'pathological cases' that can lead to significant misestimates of a digitizer's performance. The aim of these evaluation procedures is consis....; Authors:Green;P.J.Publisher:Instrumentation and Measurement Technology Conference;1990. IMTC-90.

The Ultra-Zener-a portable replacement for the Weston cell?: Twenty-four samples of the Ultra-Zener, an integrated circuit containing a buried Zener junction, type no. LTZ 1000, have been tested since March 1988. With some circuit modification, half of the samples have been found to have an aging rate of less than 1.5 p.p.m./year, and all have an aging rate of less than 4 p.p.m./year. The initial tests indic....; Authors:Spreadbury;P.J.Publisher:Precision Electromagnetic Measurements;1990. CPEM '90 Digest.;Conference onConference Date:11-14 June 1990ISSN:Total Page:xxiv+446

Design, calibration and evaluation of a two axis correlation log for use on autonomous underwater vehicle: The design of a specific correlation speed log system developed to meet the requirements for relatively low-cost, high-performance submersible mounted operation is presented. The installation calibration of high-performance speed logs on surface vessels is important in order to identify and minimize the effects of installation misalignments. The ha....; Authors:Stevens;P.J.Publisher:Autonomous Underwater Vehicle Technology;1990. AUV '90.;Proceedings of the (1990) Symposium onConference Date:5-6 June 1990ISSN:Total Page:317

Ground based observations to probe the ionospheric and magnetospheric plasmas: Summary form only given. Ground-based, or near-ground-based, observations of particles, currents, and fields have yielded important information when studying both local and global magnetospheric phenomena. A great variety of instruments and techniques have been developed to carry out measurements from ground of phenomena which are of such an extent....; Authors:Tanskanen;P.J.Publisher:Plasma Science;1990.

Factors affecting accuracy of quantitative blood flow measurements by duplex ultrasound: The effect of both physiologic variables and hardware variables on the accuracy of duplex ultrasound volume flow measurements was investigated with an in vivo model under controlled laboratory conditions. Changes in physiologic variables such as heart rate, cardiac output, vessel compliance and fluid volume consistently caused >10 % error in me....; Authors:Bendick;P.J.Publisher:Ultrasonics Symposium;1990.

Correlation of ultrasonic image features with histologic characteristics of atherosclerotic plaque: A study was undertaken to determine the ability of preoperative duplex sonography to characterize carotid atherosclerotic lesions and to correlate these findings with histologic studies of carotid endarterectomy specimens in order to establish the reliability of noninvasive ultrasound in assessing plaque morphology. Regions of uniform echogenicity ....; Authors:Bendick;P.J.Publisher:Ultrasonics Symposium;1990. Proceedings.;IEEE 1990Conference Date:4-7 Dec. 1990ISSN:Total Page:3 vol. 1673

Managing open networks: The progress and schedules associated with OSI management standardization, and efforts to define network management requirements, are reviewed; the author synopsizes the ISO efforts to standardize management communication services for specific functional areas of management, reviews efforts to integrate network management across ISO and non-ISO env....; Authors:Brusil;P.J.Publisher:Computers and Communications;1988.

An integrated process controller chip: A description is given of the development of an LSI circuit chip that finds use in a textile dyeing machine called JIGGER. Until now a semielectrical system was utilized to control the various operations in the process cycle. The various design steps involved and the use of novel design-for-testability features are also described. Possible future i....; Authors:Krishnan;P.J.Publisher:System Theory;1988.;Proceedings of the Twentieth Southeastern Symposium onConference Date:20-22 March 1988ISSN:0-8186-0847-1Total Page:xix+697
