This paper describes an ongoing study into the quality of service provided by the Irish Revenue Commisioners’ on-line tax filing and collection system. The Irish Revenue On-Line Service (ROS) site has won several awards. In this study, a version of the widely used SERVQUAL measuring instrument, adapted for use with on-line services, has been modified for the specific case of ROS. The theory beh...

The quality of audio in IP telephony is significantly influenced by the impact of packet loss rate, burstiness and distribution on audio compression techniques. On-line audio quality assessment is important to provide real-time feedback to end-to-end Internet audio transport protocols to increase the reliability and quality of the audio session. In this paper we propose a novel passive statisti...

This paper introduces objective macro and micro line egistration quality metrics based on Moiré interference patterns enerated by superposing a lenticular lens grating over a hardcopy est page consisting of high-frequency Ronchi rulings. Metrics for acro and micro line registration are defined and a measurement rocedure is described to enha...

Online quality assessment of various horticultural products using machine vision provides not only quick but also objective, consistent and quantitative measurement. Horticultural products of different sizes and shapes (circular or elliptical) are classified based on the area occupied, which is calculated by known geometrical method. Another factor in the classification is the detection of defe...

A new method of surface-quality assessment is presented. The model of highlight lines is introduced, and its properties and applications in surface-quality evaluation are demonstrated. The differential equation of the highlight-line model is derived, and the difficulty involved in seeking its analytical solutions is discussed. Alternatively, the creation of highlight lines is formulated as a su...

Qualified forensic document examiners from Canada, USA, Great Britain and Australia participated in this study. They were sent one photocopied signature, together with a set of original known standards to evaluate the line quality of the photocopied signature and compare these characteristics with the standards. They were asked to assess the photocopies for the presence of tremor, hesitation, p...

. In order to improve the quality of service co-production, both academics and managers have pointed out the pivotal role of Front line Employees (FLEs) in improving the service experience. However, few studies have simultaneously examined the quality perceptions of each group. Do FLEs perceive service quality in the same way as their customers? If this is the case, service quality itself will ...

A on-line monitoring new method for grinding quality is presented based on theory analysis and test study, which collects the information of grinding quality from the AE signals produced by friction and grinding process to realize the on-line intelligent detection and prediction of grinding quality by A wavelet neural network & Fuzzy BP algorithm based network. The reliability and feasibility o...

Information, stored in databases, is a key competitive advantage of many companies. However, this importance does not imply that managers will view data as a strategic resource or that they have the experience to interpret business processes in terms of data management. One way to overcome this corporate inexperience is to establish a data quality system a controlled and robust process that exe...
