    Abraham Bennet, the inventor of the leaf electroscope, devised a three-plate procedure for doubling electric charge. Like so many other manual processes in the 18th century it was ripe for deskilling by mechanisation, and it was William Nicholson who mechanised it. Here, the author describes a replica of Nicholson's doubler which he has constructed and the difficulties he encountered in making it perform in the manner described by Nicholon View full abstract»

  • Risk assessment: subjective or objective?

    Identified are many common problems/misunderstandings that engineers involved in risk assessment have raised in dealing with the concepts of risk assessment (RA, as defined in the management of Health and Safety at Work Regulations 1992). In particular concerns, reservations and confusion about the use of subjective risk estimation and the development of procedures for risk estimation appear to be causing undue difficulties in dealing with the regulations. This article suggests that risk estimation by itself has, in fact, little direct value to safety improvement and that a more tentative approach to RA can be formulated wherein risk estimation becomes an occasional rather than pivotal element of the risk assessment process View full abstract»

  • Around the world by balloon: an electrical perspective

    Publication Year: 1998 , Page(s): 71 - 80

    A number of teams are currently attempting to become the first to circumnavigate the globe by balloon. In each case, their equipment must be capable of operating continuously, without malfunction, for over 500 hours. This is a significant engineering challenge, as the many failures to date have highlighted. The purpose of this paper is to outline some of these challenges, particularly in the electrical and communication engineering fields, and to examine the various solutions adopted by some of the main contenders in this the `last great aviation challenge' View full abstract»

  • Focused ion beams for microfabrication

    Publication Year: 1998 , Page(s): 53 - 56

    Focused ion beam (FIB) techniques are commonly used in microelectronics for prototyping, failure analysis and process control. With the growing interest in MEMS (micro-electro-mechanical systems) the importance of FIB techniques in this field has to be established. For the FIB to be considered for production, the milling time is crucial. Using as an example the fabrication of a microaccelerometer structure the authors show there is scope for the FIB in the prototyping and production of micromechanical structures, leading to novel sensors View full abstract»

    Under the 4th Framework of the European Union (EU), the Training and Mobility of Researchers (TMR) programme has provided many post-graduate and post-doctoral researchers, now known as Marie Curie Fellows, the opportunity to expand their skills by conducting research in another EU country. Participants in the TMR programme gain international experience and training that should greatly enhance their career prospects. Improving Human Potential (IHP) is the name being given to the new scheme proposed in the 5th Framework to overtake the current TMR programme. The goals proposed for IHP are outlined, and same of the experiences and benefits provided by the TMR programme to both the UK and European research communities are highlighted View full abstract»

    Expert systems are computer programs designed to model the problem-solving ability of human experts. They have experienced tremendous growth and popularity since their commercial introduction in the early 1980s. Expert systems are now used in areas such as business, medicine, science, engineering and manufacturing. Their applications to the field of education have also provided extensive opportunities. In this study the effectiveness of an expert system as an educational tool is demonstrated by considering a typical case where an expert system was successfully developed to aid the teaching of digital electronics. A brief description of expert systems is provided and the steps followed to develop the required system are outlined. The techniques described can easily be adapted to a variety of other similar applications View full abstract»
