The detection, location, and sizing of a fatigue crack emanating from a fastener hole in an aluminum plate is investigated. Two linear arrays of surface mounted piezoelectric disk transducers send and receive ultrasonic guided waves that are transmitted, reflected, and scattered by both the joint geometry and the fatigue crack. A tomography algorithm is used to detect and locate the crack. Ampl...

Currently in the United Kingdom there are over 100 bridges containing hinge joint components, introduced to simplify and standardise designs. Visual inspection of hinge joints noted bridge deck waterproofing failure, which can cause steel reinforcement bar corrosion. This reinforcement is crucial to the integrity of the joint, and the loss of reinforcement section can induce higher stresses lea...

Satisfactory performance of the transverse joints is crucial for achieving the intended service life of jointed plain concrete pavement. An accurate prediction of joint opening and movement is desired in order to quantify the effects of the environment, base type, concrete material constituents, and slab geometry on the concrete pavement responses. In this paper, an analytical model based on el...

What kinds of processes and representations make joint action possible? In this paper, we suggest a minimal architecture for joint action that focuses on representations, action monitoring and action prediction processes, as well as ways of simplifying coordination. The architecture spells out minimal requirements for an individual agent to engage in a joint action. We discuss existing evidence...

We surveyed the current practice of local anaesthesia for routine ocular surgery by consultant anaesthetists in the Wessex region using a postal questionnaire. Most consultants were in agreement concerning the type and technique of block, and monitoring to be used during local anaesthesia for ocular surgery. The issue of teaching for trainee anaesthetists produced a varied response. We found th...

The increase in use of endoscopic procedures in diagnosis and surgical treatment has underlined the need for safe cleaning methods for these instruments. While decontamination has been reviewed by several Working Groups in Britain, the problems relating to the prevention of contamination of rinse water and its monitoring procedures have not been addressed previously. This report from the Joint ...

We study how to learn to play a Pareto-optimal strict Nash equilibrium when there exist multiple equilibria and agents may have different preferences among the equilibria. We focus on repeated coordination games of non-identical interest where agents do not know the game structure up front and receive noisy payoffs. We design efficient near-optimal algorithms for both the perfect monitoring and...

Purpose Monitoring disease activity of chronic arthritis is still a major challenge in clinical praxis. Activated macrophages play a crucial role during joint inflammation. Expression of myeloid related protein 14 (MRP14) by activated macrophages correlates with disease activity in different forms of arthritis. We analyse the use of Cy5.5-labelled antibodies against MRP14 for monitoring of infl...

Joint Monitoring of Several Types of Shocks in Dynamic Linear Models: A Bayesian Decision Approach Abstract In this paper we consider the sequential monitoring process in Dynamic Linear Models as a Bayesian sequential decision problem. By using this approach we build a general procedure that jointly analyses the existence of outliers, level changes, variance changes and development of local cor...

We present a printable interdigital structure, integrated into the surface of a component, to monitor the curing of two adhesively joint components during the fabrication process. In the factory of the future there is a need of new sensor concepts beside the information technological infrastructure. Monitoring of the fabrication enables automated control of the process which improves the qualit...
