An Active Robust Optimisation Problem (AROP) aims at finding robust adaptable solutions, i.e. solutions that actively gain robustness to environmental changes through adaptation. Existing AROP studies have considered only a single performance objective. This study extends the Active Robust Optimisation methodology to deal with problems with more than one objective. Once multiple objectives are ...

Two circuit modelling and parameterisation techniques for optimisation of a left-handed microstrip transmission line for antenna applications are presented. Such a transmission line is characterised by high transmission loss ripples in the required frequency band, which hinders its use as a wideband feeding network in antenna array applications. The first circuit modelling technique is based on...

An equivalent circuit model is the most common and straight-forward way of representing the dynamic behaviour of a lithium-ion battery. In literature, many examples of circuits are proposed and various techniques are also discussed for parameterisation of the models. In this paper a second order equivalent circuit is proposed and the parameters identification method by Hybrid Power Pulse Charac...

Analog circuit design can be formulated as a non-linear constrained optimisation problem that solved using any suitable algorithms. Different techniques have been reported to reduce the time of analog circuits. A hybrid particle swarm algorithm with linearly decreasing inertia weight for is proposed in this study. The method used two-stage operational amplifier Miller compensation. results show...

a novel approach to determine optimal sampling locations under parameter uncertainty in a water distribution system (wds) for the purpose of its hydraulic model calibration is presented. the problem is formulated as a multi-objective optimisation problem under calibration parameter uncertainty. the objectives are to maximise the calibrated model accuracy and to minimise the number of sampling d...
