3D Simulation of Partial Discharge in High Voltage Power Networks
Ragusa, Antonella; Sasse, Hugh G.; Duffy, A. P. (Conference)Partial discharge (PD) events arise inside power cables due to defects of cable’s insulation material, characterized by a lower electrical breakdown strength than the surrounding dielectric material. These electrical ... -
Analysing transient phenomena in the time domain using the Feature Selective Validation (FSV) Method
Jauregui, R.; Zhang, Gang; Rojas-Mora, J.; Ventosa, O.; Silva, F.; Duffy, A. P.; Sasse, Hugh G. (Article)The increasing application of simulation tools to increasingly complex problems makes the use of validation tools essential to improve confidence in the veracity of those simulation results. IEEE Standard 1597.1 is the ... -
Analysis and modelling of structured wiring communication channels
Al-Asadi, M. M.; Duffy, A. P.; Hodge, K.; Willis, A. J. (Article)The authors present equations for the calculation of the attenuation constant of both unshielded and shielded cables as a function of cable dimension, material parameters and frequency of operation. An analytical approach ... -

Classification and Clustering Approaches to Understanding Customer Ordering by Customers of a Fresh Food Supplier
Clement, Ross; Kang, Parminder Singh; Duffy, A. P.; Hopewell, Ashley (Conference)Purpose: This paper looks at characterization of B2B customers of a fresh food wholesale company supplying SME clients in terms of their weekly orders of a variety of fresh products. Customers whose orders can be predicted ... -
Closing remarks: Standards as living documents

Comparison of 3-dimensional datasets by using the generalized n-dimensional (n-D) Feature Selective Validation (FSV) technique
Zhang, Gang; Orlandi, A.; Duffy, A. P.; Wang, Lixin (Article)Automatic methods to evaluate the validity of computational electromagnetics computer modeling and simulations have widespread applications. The Feature Selective Validation method is a heuristic technique which has been ... -
Comparison of Data with Multiple Degrees of Freedom Utilizing the Feature Selective Validation (FSV) Method
Zhang, Gang; Duffy, A. P.; Orlandi, A.; Di Febo, D.; Wang, Lixin; Sasse, Hugh G. (Article)The feature selective validation method has been shown to provide results that are in broad agreement with the visual assessment of a group of engineers for line, 1-D, data. An implementation using 2-D Fourier transforms ... -
Competitive Intelligence and Information Technology Adoption of SMEs in Turkey: Diagnosing Current Performance and Identifying Barriers
Wright, Sheila; Bisson, C.; Duffy, A. P. (Article)The need for SMEs to behave in a more concise and coherent competitive fashion is well recognised. This study reports on an empirical study of SMEs in Turkey. Their responses were applied to a behavioural and information ...
