The computation of the frequency response of systems depending affinely on uncertain parameters can be reduced to that of all its one-dimensional edge plants while the image of such an edge plant at a fixed frequency is an arc or a line segment in the complex plane. Based on this conclusion, four computational formulas of the maximal and minimal (maxi-mini) magnitudes and phases of an edge plant at a fixed frequency are given. The formulas, besides sharing a simpler form of expression, concretely display how the extrema of the frequency response of the edge plant relate to the typical characteristics of the arc and line segment such as the centre, radius and tangent points of the arc, the distance from the origin to the line segment etc. The direct application of the results is to compute the Bode-, Nichols-and Nyquist-plot collections of the systems which are needed in robustness analysis and design.

As part of a CEC MAST 3 project entitled PROSIM, (propagation channel simulator), the Ocean Systems Laboratory at Heriot-Watt University was given the task of planning and performing acoustic data gathering experiments off the west coast of Scotland, in the Clyde due west of Ayr, in the summer of 1997. The PROSIM project has as its aim the development of a software channel model simulator that will be able to predict or simulate the effect of a broadband audio frequency source (400 Hz to 15 kHz), in shallow water acoustic channels, at realistic long ranges. Sea surface, sea bottom and propagation effects are included in this simulator design. The University of Wales Marine Science Laboratories had the task of collecting oceanographic data during these trials. Acoustic and oceanographic data collected during these (and other) trials are used to assist in the validation of the PROSIM channel simulator. Selected data are also supplied to the UK Oceanographic Data Centre where it is available for use by EC acoustics researchers. Much of the receive equipment, both acoustic and data recording had been developed during a previous CEC MAST 2 project which had used omni-directional acoustic projectors in the 20 kHz to 80 kHz band. Under this project entitled EEVMAC (European experimental validated model for acoustic channels) a high level control strategy based on a LABVIEW environment had been developed which allowed full PC control over both the transmit and receive ships experimental equipment.

The possibility of building systems using pre-existing Commercial Off-The-Shelf (COTS) components is investigated with the growing complexity and cost involved in the development of safety critical applications, but a number of problems are posed in attempting to integrate COTS components in larger systems developments. These problems include the potential for introducing systematic errors through component mismatch and meeting the obligations of the systems safety case. These two problems and the solutions to solve these problems by using appropriate and sufficient documentation of COTS components are discussed.
