The mathematical components of engineering expertise: the relationship between doing and understanding mathematics

this paper are extracts from our interviews with engineers.) Where, then, is the complex mathematics that certainly exists in modern engineering? Throughout all aspects of engineering design, computer software has an overwhelming presence. Also, in the particular firm that we visited, there a small number of analytical specialists (a few per cent of the professional engineers employed) who act as consultants for the mathematical/analytical problems which the general design engineers cannot readily solve. (In general in structural engineering, such specialist work is often carried out by external consultants, eg. academic researchers

General Relativity in Electrical Engineering

In electrical engineering metamaterials have been developed that offer unprecedented control over electromagnetic fields. Here we show that general relativity lends the theoretical tools for designing devices made of such versatile materials. Given a desired device function, the theory describes the electromagnetic properties that turn this function into fact. We consider media that facilitate space-time transformations and include negative refraction. Our theory unifies the concepts operating behind the scenes of perfect invisibility devices, perfect lenses, the optical Aharonov-Bohm effect and electromagnetic analogs of the event horizon, and may lead to further applications

A new educational program on biomedical engineering

At the University of Twente together with the Free University of Amsterdam a new educational program on Biomedical Engineering will be developed. The academic program with a five-year duration will start in September 2001. After a general, broad education in Biomedical Engineering in the first three years, the students specialise in one of the following areas: materials and tissue engineering; technology for restoration of human function; healthcare technolog

A lightweight, pattern-based approach to identification and formalisation of TimeML expressions in clinical narratives

General Architecture for Text Engineering (GATE) components for identifying clinical events and temporal expressions are developed and evaluated against a corpus of 120 discharge summaries

Bases of inorganic and organic chemistry

Stated fundamental theoretical principles of general, inorganic and organic chemistry and analyzed the reactivity of the most important classes of inorganic and organic substances. A multivariate tasks and exercises for classroom and independent work are proposed. For university students full-time and distance learning areas "Chemical Technology and Engineering" "Oil and gas engineering and technology" and others
