Abstract

Examines the situation in the UK in some detail with regard to three aspects of the Charter of Fundamental Human Rights of the European Union. Looks at the aims, together with an analysis and appraisal. Considers, first, information and consultation rights with regards to the transfer of undertakings and redundancies, followd by the right to collective action and, lastly, protection in the event of unjustifiable dismissal. Presents case law throughout as examples. Concludes that the UK has attempted to prevent social and economic rights for workers from being included in the final charter despite fierce opposition. Compares this view together with the UK suspicion of Europe against the views of the other member states.

Abstract

Purpose

For oil film thickness measurement using ultrasonic spring model, obtaining the isolated reflection from the oil film layer is the key point. While for oil film thickness measurement in thrust bearings with thin liner, the reflection from the substrate-Babbitt interface will overlap with the reflection from the oil film layer. This overlapping will render the ultrasonic spring model invalid. To obtain the isolated reflected signal from the oil film layer accurately, an adaptive method was developed to recover the overlapping echoes.

Design/methodology/approach

A genetic-algorithm-based support matching pursuit (GA-based SMP) was developed to provide the optimal echo number and initial parameters guesses automatically and efficiently. Then, the traditional expectation maximization (EM) model was used to fine tune the accurate results.

Findings

The developed method was tested using both simulated echoes and the overlapping echoes encountered in the ultrasonic oil film thickness measurement of thrust bearings. The results demonstrated that the developed method performed well on recovering overlapping echoes adaptively.

Originality/value

The work shows an adaptive method to recover the ultrasonic overlapping echoes. When used in ultrasonic oil film thickness measurement, it can help extend the application of traditional ultrasonic spring model to objects with four or more layers.

Abstract

Government appointed and sponsored committees of every description—select, ad hoc, advisory, inquiry—such a prominent feature of the public scene since the last War, are understandable, even acceptable, reflect the urgency of the times in which we live. In the gathering gloom of more recent twilight years, they have flourished inordinately, especially in the socio‐political field, where most of their researches have been conducted. Usually embellished with the name of the figure‐head chairman, almost always expensively financed, they have one thing in common—an enormous output of words, telling us much of what we already know. So much of it seems dull, meaningless jargon, reflecting attitudes rather than sound, general principles.

Abstract

This paper summarises briefly all the substitutive techniques for CFC‐113 and 1,1,1 ‐trichloroethane blend cleaning, including the use of ‘no‐clean’ and controlled atmosphere soldering, with emphasis on high‐reliability applications. Each technique is discussed with regard to its influence on the final reliability of the assembly under normal and abnormal storage and working conditions. Reliability is determined by numerous other parameters which are frequently ignored, such as the component layout for best cleaning quality. The requirements of conformal coating are also frequently given scant attention. In practical terms, this paper may help those selecting a substitutive soldering/cleaning process to choose one which will meet their quality requirements at minimum cost.

Abstract

The electronics industry faces a serious challenge in its approach to the cleaning of printed circuit boards after reflow soldering. A unique approach has been adopted to give invariant viscosity, hot/wet slump resistance and low residue solder pastes. Carefully tailored activation systems provide effective reflow and benign no‐clean residues. High metal loadings are incorporated with fine pitch capability and consistency of product.

Abstract

Purpose

Rotating machineries are widely used in manufacturing, petroleum, chemical, aircraft, and other industries. To accurately identify the operating conditions of such rotating machineries, this paper aims to propose a fault diagnosis method based on sensitive dimensionless parameters and particle swarm optimization (PSO)–support vector machine (SVM) for reducing the unexpected downtime and economic losses.

Design/methodology/approach

A relatively new hybrid intelligent fault classification approach is proposed by integrating multiple dimensionless parameters, the Fisher criterion and PSO–SVM. In terms of data pre-processing, a method based on wavelet packet decomposition (WPD), empirical mode decomposition (EMD) and dimensionless parameters is proposed for the extraction of the vibration signal features. The Fisher criterion is applied to reduce the redundant dimensionless parameters and search for the sensitive dimensionless parameters. Then, PSO is adapted to optimize the penalty parameter and kernel parameter for SVM. Finally, the sensitive dimensionless parameters are classified with the optimized model.

Findings

As two different time–frequency analysis methods, a method based on a combination of WPD and EMD used to extract multiple dimensionless parameters is presented. More vital diagnosis information can be obtained from the vibration signals than by only using a single time–frequency analysis method. Besides, a fault classification approach combining the sensitive dimensionless parameters and PSO-SVM classifier is proposed. The comparative experiment results show that the proposed method has a high classification accuracy and efficiency.

Originality/value

To the best of the authors’ knowledge, very few efforts have been performed for fault classification using multiple dimensionless parameters. In this paper, eighty dimensionless parameters have been studied intensively, which provides a new strategy in fault diagnosis field.

Abstract

Explains how the Pacific Northwest Regional Library converted catalog records from the OCLC MARC Tape Service into a working database by loading the tapes onto a minicomputer and then downloading the data onto diskettes. Tackles the problems that were encountered as a result of this when the database was set up.

Abstract

The use of sequence and structure databanks is examined in relation to their application in some of the main branches of protein studies. Also the question of availability is addressed by means of presenting some information on current sequence and structure databanks. Increasingly research in molecular science requires joint access to both sequence and structure databases, and the reasons for this development, together with some of the methods for integrated access, are analysed.

Abstract

Legal process by its very nature cannot be swift; step by step, it must be steady and sure and this takes time. There is no room for hasty decisions for these would tend to defeat its purpose. Time, however, is of the essence and this is set for various aspects of legal action by limitation of actions legislation, which sets periods after which the case is no longer actionable. The periods are adequate and in civil law, generous to avoid injustice being done. The one serious complaint against the process of law, however, is the unwarrantable delays which are possible despite limitation. From the far‐off days of Equity, when Dickens' Jarndyce v Jarndyce, caricatured and exaggerated as it was, described the scene down to the present when delays, often spoken of in Court as outrageous are encountered, to say nothing of the crowded lists in the High Courts and Crown Courts; the result of the state of society and not the fault of the judiciary. Early in 1980, it was reported that 14,500 cases were awaiting trial in the Southeastern Circuit Crown Court alone. Outside the Courts legal work hangs on, to the annoyance of those concerned; from house purchase to probate. Here, the solicitor is very much his own master, unhampered by statutory time limits and the only recourse a client has is to change this solicitor, with no certainty that there will be any improvement, or appeal to the Law Society.
