    The firm of Thomas Bolton & Sons grew out of a business producing metal buckles into one of the world's leading wire, especially electrical wire, manufacturers. This article traces the development of the company from its early years in the late 18th century to its takeover by the cable companies in 1961. Important stages in the company's growth were marked by the introduction of cold drawing and continuous wire drawing to meet the demand for long lengths of high-conductivity, high-tensile-strength copper wire for the telegraph and telephone industries View full abstract»

    The rise of green consumerism led to a proliferation of products claiming to be environmentally friendly, however consumers often found the statements given in support of these claims confusing. `Ecolabels' are intended to help consumers recognise products which have been manufactured and which perform their intended function in an environmentally friendly way. This article gives an overview of the current position regarding ecolabelling within the Member States of the European Union (EU) and proposals for strengthening the EU Ecolable Regulations View full abstract»

  • 3D UV-microforming: principles and applications

    Page(s): 13 - 19

    A low-cost surface micromachining technology is described and examples provided of its application to microsensor and microactuator fabrication. The new technology 3D UV-macroforming, combines depth ultraviolet (UV) lithographic patterning of very thick photoresists and electrodeposition of structural materials into the patterned resist moulds. Neither UV lithography nor electrodeposition needs expensive or special equipment. Micromechanical components with high structures can be directly manufactured onto the system surface. Movable three-dimensional (3D) microstructures with a high aspect ratio can be obtained by combining the 3D UV-microforming process with a sacrificial layer technique. As an example of an advanced application in microsystem technology, the fabrication of triaxial accelerometers is presented, using titanium as a sacrificial layer and nickel as the structural material View full abstract»

  • Computer aided circuit analysis and design projects for electronic engineering students

    Page(s): 23 - 32
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (1800 KB)  

    The integration of circuit simulation programs into an undergraduate electronics curriculum is discussed. Several projects are presented which combine application of a computer package with corresponding practical experiments in the electronics laboratory. In this way, students learn that electronic circuits are not simply blackboard theory but tangible objects which only given the optimum performance predicted by theoretical analysis following a careful design, simulation and test. Furthermore, some ideas for diploma thesis projects are presented, which offer students an opportunity to understand better the limitations of the software package and to extend its capabilities to new applications View full abstract»

  • Intracranial hypertension: condition monitoring, simulation and time domain analysis

    Page(s): 33 - 40
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (2196 KB)  

    This paper discusses developments in the measurement and simulation of intracranial pressure in humans and recent research carried out by the authors on techniques for the noninvasive measurement of intracranial pressure. A simulation of the dynamics of the human brain has been carried out based on a six compartment resistive, compliant model and serves as an indicator of time domain phase changes between intracranial blood pressure and blood velocity. This paper concentrates on the time domain experiments and analysis that were used in validating the simulation and developing a noninvasive approach to the measurement of intracranial pressure. The time domain analysis uses the cross-correlation of the blood flow velocity of the middle cerebral artery with blood pressure measurements and their varying phase shift with trauma characteristics to make predictions of intracranial pressure trends that lead to pathologically dangerous conditions. The development of software and associated graphical displays that could inform the nursing staff of trends in intracranial pressure is outlined View full abstract»
