Implementation of virtual manufacturing by a technology licensing company
NoThe paper considers the implementation of a virtual manufacturing system as an alternative to outward technology licensing in a high technology industrial sector. Brief theoretical definition and description of the two strategy options is provided to give background and context. This is followed by empirical material from a longitudinal case study of a company that has developed a virtual manufacturing system in addition to its pre-existing outward technology licensing business stream. A summary account of the company history and development is followed by description of the virtual manufacturing proposal. Analysis of this identified a number of competencies that would be required in order to succeed. The final part of the paper describes the company's response to this analysis and discusses early implementation of the virtual system. It is shown that implementation of the proposal has represented a positive response to the business challenges facing the company
Fiber optic data bus using Frequency Division Multiplexing (FDM) and an asymmetric coupler
A fiber optic data bus, using frequency division multiplexing (FDM) is discussed. The use of FDM is motivated by the need to avoid central control of the bus operation. A major difficulty of such a data bus is introduced by the couplers. An efficient low loss access coupler with an asymmetric structure is presented, and manufacturing processes for the coupler are proposed

Quasar-galaxy associations
There is controversy about the measurement of statistical associations
between bright quasars and faint, presumably foreground galaxies. We look at
the distribution of galaxies around an unbiased sample of 63 bright, moderate
redshift quasars using a new statistic based on the separation of the quasar
and its nearest neighbour galaxy. We find a significant excess of close
neighbours at separations less than about 10 arcsec which we attribute to the
magnification by gravitational lensing of quasars which would otherwise be too
faint to be included in our sample. About one quarter to one third of the
quasars are so affected although the allowed error in this fraction is large.Comment: uuencoded Postscript file (including figures and tables), SUSSEX-AST
