This research was designed to evaluate and compare the applicability of two different types of irrigation including traditionally (surface irrigation) and simple sub-surface drip irrigation (using pricked-pipe covered with plastic cloth). Two plots containing 39 pistachio trees with 720 m2 area were selected in Rafsanjan, Iran. Both plots were irrigated using exactly the same quantity and quali...

This paper examines clustering in datasets where each record is presented as a curve (trend). Our clustering approach is based on nonsmooth and nonconvex optimisation, namely the clustering problems have been formulated as mathematical programming problems and several optimisation methods from GANSO optimisation library have been applied to solve the problems. The least squares and uniform opti...

A novel implementation of a space-mapping (SM) algorithm for optimisation of microwave structures and devices is described. The algorithm uses two techniques to speed up the SM optimisation process: the evaluation of the fine model is distributed through independent processing of the fine model response corresponding to consecutive frequency samples using a number of CPUs, and the parameter ext...

Software testing is a crucial part of software development. It enables quality assurance, such as correctness, completeness and high reliability of the software systems. Current state-of-the-art software testing techniques employ search-based optimisation methods, such as genetic algorithms to handle the difficult and laborious task of test data generation. Despite their general applicability, ...

An optimum design course is being taught to undergraduate students as a basic discipline in engineering and technology education. Optimum design aims primarily at determining the best possible combination of solutions used as design parameters to maximise or minimise an optimisation problem. The development of conventional optimum approaches has dramatically influenced modern teaching technolog...

In many application domains, optimisation, decision analysis and other analytic models are often embedded as a decision engine within the respective business processes. In order to respond effectively to global as well as regional competition, successful companies have started to formalise and improve their Business Process Management (BPM) procedures. In this paper, we study recent trends in t...
