摘要:

The paper surveys the 20 or so decades of frequency of the electromagnetic spectrum, and discusses both the energy and information which can be extracted from it. The Sun provides abundant radiant energy, which is being used to an increasing extent to provide terrestrial power.The history and use of radio waves, the visible spectrum, and X, γ and cosmic rays are examined. In recent years optical astronomy has received a boost from competition by radio astronomy. All available parts of the spectrum are now being used by both Earth and satellitebased instruments. There is rapidly-growing knowledge about the Universe and its probable origin in the Big Bang.

摘要:

Team skills may be developed in students by lectured instruction on these skills and by explicitly delegating to each team member the responsibility for applying them. This article outlines this approach and reviews student feedback on their own development.

摘要:

Part 1 of this three-part paper considered the requirement for continuing professional development (CPD). Part 2 considers a wide range of activities as potential material for a CPD portfolio, including techniques similar to those used to rate National Vocational Qualifications applied to selected working experiences as distinct from courses. Existing course credit rating systems are reviewed together with techniques for assessing or accrediting prior learning with a view to quantifying CPD, should the individual, a company, and/or a professional body require evidence for continuing or advancing professional qualification.

摘要:

Engineering competence is a fusion of many skills and attributes. The paper advocates the superiority of the industrial situation as a tool for developing the competence of undergraduate engineers. An adaptable syndicate study framework is presented, which provides an arguably better education vehicle than conventional teaching and learning methods. The advantages and disadvantages are discussed along with implications concerning pressures on teaching staff. The operational details of the framework are shown in full together with a typical example of student work. Questions are posed concerning the further development of syndicate studies and the assessment of the studies involved.

摘要:

The detection of breast cancer at an early stage is of vital importance if the high mortality rate from this disease is to be reduced. The national breast-screening programme aims to use regular X-ray examinations amongst the age group most at risk to increase the early detection rate. A result of this is that over 1 million pairs of X-ray images per year will need to be reviewed by radiologists. Over 90% of these images will show no abnormality. Potentially, the successful application of image processing techniques to this task could greatly ease the burden of the very large numbers of examinations performed, and improve detection accuracy by directing the human expert's attention only to those results suspected of being abnormal. The problem is, however, for both technical and ethical reasons, formidable.
