摘要:

Project Universe is a research project to investigate aspects of coupled local-network-based systems. Initially, there are some 15 local networks spread between seven organisations, and the various sites are connected by a 1 Mbit/s satellite link via the Orbital Test Satellite, OTS. The paper describes the architecture of the Universe network and the program support being provided to allow the network components to be bootstrapped and for experiments to be set up

摘要:

Many microprocessor teaching and development laboratories make use of a multiuser computer system for program development, and the object code is down-line loaded into the microprocessor for testing. The program development cycle of edit-compile-load can be fairly lengthy on a heavily loaded central system and it would be more desirable to use a commercially available operating system running on the microprocessor to perform program development. The operating systems will require a disc, and it may be undesirable or just too expensive to add a disc system to each microprocessor, or it may be that the central multiuser system provides other services such as printer spooling, electronic mailing and file back-up. The paper discusses an alternative method to using discs on every microprocessor, whereby the multiuser system acts as a file server to the microprocessors, thus requiring no extra cost to enhance the microprocessors to run a local operating system

摘要:

Scanning microscopy is increasingly being used because of its advantages over conventional microscopy, e.g. as improved resolution and subsurface imaging. Until recently the image was displayed on a continually refreshed long-persistence CRT. However, continuing reductions in memory costs are now permitting the economical incorporation of digital framestores which, together with low cost microprocessors, allow digital image processing techniques to be applied

摘要:

The addition of a microcomputer to a standard multichannel engineering seismograph provides a seismic processing system with enhanced processing capabilities. The resulting system is low-cost and has widespread engineering applications. Developments described in the report include a low-cost logging unit for recording data from the seismograph, an interface card for interfacing the microcomputer to either the logging unit or the seismograph, and a modular software package which provides interactive time- and frequency-domain seismic processing
