The problem of accurate determination of the position, orientation and width of involute spur gear teeth using a single front-lit image is addressed. The information is used to compute global measures of tooth concentricity and pitch variations across a gear wheel. The approach is based on the use of specialised filters which make maximum use of the grey level information available in the image...

This paper presents a new Integrated Technical Reference Model (I-TRM) using a multilayered architecture. Most existing technical reference models concentrate on one aspect of a system, like information processing or control structure. The I-TRM is based on a classical closed-loop control system. It combines an Information-Centric Technical Reference Model (IC-TRM), a Control Technical Referenc...

We propose a server-centric architecture for P3P that reuses database technology for implementation, as opposed to the prevailing client-centric implementations based on specialized engines. The server-centric implementation has several advantages including: setting up the infrastructure necessary for ensuring that web sites act according to their stated policies, allowing P3P to be deployed in...

Recommender Systems (RSs) aim at helping users search large amounts of contents and identify more effectively the items (products or services) that are likely to be more useful or attractive. The quality of a RS can be defined from two perspectives: system-centric, in which quality measures (e.g., precision, recall) are evaluated using vast datasets of preferences and opinions on items previous...

Purpose This study aims to extend understanding of business-to-business relationship dynamics by introducing and discussing the phenomenon of a 'negative critical wave' (NCW), defined as a disturbance in a relationship that emerges and develops within or beyond individual working relationships. Design/methodology/approach The dynamics of working relationships in two manufacturing firms in Finla...

The purpose of this study was to test the possible differences in centric slide values between different Angle's classes of occlusion. The study included 98 participants divided into four groups: Angle's class I, Angle's class II, subdivision 1, Angle's class II, subdivision 2 and Angle's class III. All recordings were obtained using an ultrasound jaw tracking device with six degrees of freedom...

Static index pruning methods have been proposed to reduce size of the inverted index of information retrieval systems. The goal is to increase efficiency (in terms of query response time) while preserving effectiveness (in terms of ranking quality). Current state-of-the-art approaches include the term-centric pruning approach and the document-centric pruning approach. While the term-centric pru...
