In response to the growing demand for better performance, multicore platforms have become ubiquitous. A critical problem is that the diversity of hardware and software characteristics is increasing, making it a great challenge for parallel application developers to optimize performance and preserve application portability. In addition, unknown workload compositions and run-time interferences ma...

By reversing paradigms that normally utilize mathematical models as the basis for nonlinear adaptive controllers, this article describes using the controller to serve as a novel computational approach for mathematical system identification. System identification usually begins with the dynamics, and then seeks to parameterize the mathematical model in an optimization relationship that produces ...

Demand for capacity and bandwidth increasing day-by-day in the area of wireless communication. One of the solutions is the utilization of frequency bands for broadband communication that is related to satellite communication. Mostly Ka-band is used in satellite communication. In this paper, an attempt is taken to design an optimized resonant-cap Ka-band oscillator. To obtain oscillation from Ka...

A thin film coating of titanium nitride was applied to the surface of rf cavity tuners to reduce secondary electron generated when the existing copper base material is in place. The tuners are used in high-field gradients, where electron heating of the tuner is a problem. By reducing the generation of electrons the temperature of the tuners will be reduced, for better reliability. This paper co...

This document is the case for support for Grant number EP/H004092/1, funded by the EPSRC in the UK. Our aim is to improve dramatically the scalability of constraint technology, while removing its reliance on manual tuning by an expert. This aim will be realised through the development of a constraint solver synthesiser, the principal components of which are a Model Analyser, a Constraint Solver...
