A strategy for semantic integrity enforcement in a parallel database machine (1994)
Presentation / Conference Contribution
McCarroll, N., & Kerridge, J. (1994, July). A strategy for semantic integrity enforcement in a parallel database machine. Presented at Directions in Databases: 12th British National Conference on Databases, BNCOD 12, Guildford, UK

Semantic integrity constraints represent knowledge about data with which a relational database must be consistent. To enforce semantic integrity we must ensure that transactions which alter the database will preserve database consistency by accompany...

A conceptual language for querying object oriented data (1994)
Presentation / Conference Contribution
Barclay, P. J., & Kennedy, J. (1994, July). A conceptual language for querying object oriented data. Presented at 12th British National Conference on Database: Directions in Databases - BNCOD12, 1994

A variety of languages have been proposed for object oriented database systems in order to provide facilities for ad hoc querying. However, in order to model at the conceptual level, an object oriented schema definition language must itself provide f... Read More about A conceptual language for querying object oriented data.

Presentation / Conference Contribution
Paechter, B. (1994, April). Optimising a Presentation Timetable Using Evolutionary Algorithms. Presented at AISB EC: AISB Workshop on Evolutionary Computing, Leeds

This paper describes a solution to the problem of scheduling student presentations which uses evolutionary algorithms. The solution uses a permutation based approach with each candidate schedule being coded for by a genotype containing six chromosome...

An experimental 3D interface to an object oriented database is described. It is hoped that using such techniques will help make complex data structures more comprehensible and easier to navigate. A number of 3D visualisation techniques are used to en... Read More about Three dimensional interface for an object oriented database..

Application of 3D finite-difference time-domain (FDTD) method to predict radiation from a PCB with high speed pulse propagation. (1994)
Presentation / Conference Contribution
Buchanan, W. J., Gupta, N. K., & Arnold, J. M. (1994, September). Application of 3D finite-difference time-domain (FDTD) method to predict radiation from a PCB with high speed pulse propagation

The authors have applied the 3D FDTD technique to simulate the propagation of electrical signals within printed circuit boards (PCBs). This relates to the work currently being carried out into the propagation of very high speed digital pulses in PCBs...

Two solutions to the general timetable problem using evolutionary algorithms. (1994)
Presentation / Conference Contribution
Paechter, B., Luchian, H., Cumming, A., & Petriuc, M. (1994, June). Two solutions to the general timetable problem using evolutionary algorithms. Presented at First IEEE Conference on Evolutionary Computation, 1994 IEEE World Congress on Computational Intelligence

The general timetable problem, which involves the placing
of events requiring limited resources into timeslots,
has been approached in many different ways. This paper
describes two approaches to solving the problem using
evolutionary algorithms.... Read More about Two solutions to the general timetable problem using evolutionary algorithms..

A general model for the answer-pertubation techniques. (1994)
Presentation / Conference Contribution
Stamate, D., Luchian, H., & Paechter, B. (1994, September). A general model for the answer-pertubation techniques

Answer-perturbation techniques for the protection
of statistical databases were introduced in [7]; they
are flexible (perturbation kept under control),
modular (do not interact with the DBMS)
techniques, which compare fmorably to previous
protec... Read More about A general model for the answer-pertubation techniques..

Theoretical analysis of the LP mode in e-core fibre. (1994)
Presentation / Conference Contribution
Hu, X., South, R., & Rutter, M. (1994, September). Theoretical analysis of the LP mode in e-core fibre. Presented at SPIE's 1994 International Symposium on Optics, Imaging, and Instrumentation

The LP mode in e-core fiber has been analyzed theoretically. It is found that the solution of the modal fields of e-core fiber is a combination of Mathieu and modified Mathieu functions. The modal eigenvalue equations are derived. The mode nondegener... Read More about Theoretical analysis of the LP mode in e-core fibre..

Presentation / Conference Contribution
Barclay, P. J., Fraser, C., & Kennedy, J. (1992, July). Using a persistent system to construct a customised interface to an ecological db. Presented at 1st International workshop on Interfaces to Database

New applications of information technology have increasingly sophisticated user interface requirements. Such interfaces are sometimes highly application specific and therefore require to be customised to the given application area. Technology is requ...

Presentation / Conference Contribution
Waithe, S., & Kerridge, J. (1993, March). An Appreciation of the Subtleties of Shared Channels in occam3. Presented at 16th World occam* and Transputer User Group Technical Meeting (WoTUG-16), Sheffield, UK

By exploiting virtual channels implemented on the INMOS T9000 transputer, occam3 offers the facility of sharing. This allows us to declare a channel as SHARED which then allows an arbitrary number of processes to communicate across this channel. By m...
