On The Effects of Idiotypic Interactions for Recommendation Communities in Artificial Immune Systems
Journal Article
Cayzer, S., & Aickelin, U. On The Effects of Idiotypic Interactions for Recommendation Communities in Artificial Immune Systems

It has previously been shown that a recommender based on immune system idiotypic principles can outperform one based on correlation alone. This paper reports the results of work in progress, where we undertake some investigations into the nature of t...

A Hybrid Genetic Algorithm to Solve a Logt-Sizing and Scheduling Problem
Presentation / Conference Contribution
Staggemeier, A., Clark, A., Aickelin, U., & Smith, J. A Hybrid Genetic Algorithm to Solve a Logt-Sizing and Scheduling Problem.

Abstract: This paper reports a lot-sizing and scheduling problem, which minimizes inventory and backlog costs on m parallel machines with sequence-dependent set-up times over t periods. Problem solutions are represented as product subsets ordered and... Read More about A Hybrid Genetic Algorithm to Solve a Logt-Sizing and Scheduling Problem.

And now for something completely different: looking ahead to new encryption and secrecy protocols
Presentation / Conference Contribution
Ashman, H., & Gilbert, M. (2001). And now for something completely different: looking ahead to new encryption and secrecy protocols.

Transmitting sensitive data over non-secret channels has always required encryption technologies to ensure that the data arrives without exposure to eavesdroppers. The Internet has made it possible to transmit vast volumes of data more rapidly and ch...

Microstructural characterisation of TiAlTiAu and TiAlPdAu ohmic contacts to AlGaN/GaN
Book Chapter
Fay, M. W., Harrison, I., Birbeck, J., Hughes, B., Uren, M., Martin, T., & Brown, P. D. Microstructural characterisation of TiAlTiAu and TiAlPdAu ohmic contacts to AlGaN/GaN. In M. Aindow, & C. Kiely (Eds.), Electron microscopy and analysis 2001: proceedings of the Institute of Physics Electron Microscopy and Analysis Group Conference, University of Dundee, 5-7 September. IOP Publishing Ltd

Ti/Al/Ti/Au and Ti/Al/Pd/Au contacts to AlGaN/GaN have been investigated to ascertain the effect of annealing temperature on the structural evolution of the contacts. Ti/Al/Ti/Au contacts become ohmic after rapid thermal annealing at 750°C or higher,... Read More about Microstructural characterisation of TiAlTiAu and TiAlPdAu ohmic contacts to AlGaN/GaN.

Leisure, family and work in the lifestyles of dual-earner families
Presentation / Conference Contribution
Such, E. (2001). Leisure, family and work in the lifestyles of dual-earner families.

This paper examines the role of leisure in the lifestyles of dual-earner families. It explores leisure as a dimension of lifestyle that has been relatively under-researched, despite a burgeoning interest in the dual-earner family in both academic res...

State sum models for quantum gravity
Journal Article
Barrett, J. W. (2000). State sum models for quantum gravity

This paper reviews the construction of quantum field theory on a 4-dimensional spacetime by combinatorial methods, and discusses the recent developments in the direction of a combinatorial construction of quantum gravity.

Unlinked Embedded Graphs
Journal Article
Barrett, J. W. (2000). Unlinked Embedded Graphs

This paper is a self-contained development of an invariant of graphs embedded in three-dimensional Euclidean space using the Jones polynomial and skein theory. Some examples of the invariant are computed. An unlinked embedded graph is one that contai... Read More about Unlinked Embedded Graphs.

Endomorphisms of Banach algebras of infinitely differentiable functions
Journal Article
Feinstein, J., & Kamowitz, H. (1999). Endomorphisms of Banach algebras of infinitely differentiable functions

In this note we study the endomorphisms of certain Banach algebras of infinitely differentiable functions on compact plane sets, associated with weight sequences M. These algebras were originally studied by Dales, Davie and McClure. In a pr... Read More about Endomorphisms of Banach algebras of infinitely differentiable functions.
