TL;DR: A novel method for controlling the convergence rate of a particle swarm optimization algorithm using fractional calculus (FC) concepts and the FC demonstrates a potential for interpreting evolution of the algorithm and to control its convergence.

TL;DR: The particle swarm optimisation algorithm is proposed as a new method to design a model-based predictive greenhouse air temperature controller subject to restrictions and its performance is compared with the ones obtained by using genetic and sequential quadratic programming algorithms to solve the constrained optimisation air temperature control problem.

TL;DR: A new approximation algorithm for establishing the fractional order electrical potential and analyzes its characteristics is developed.

TL;DR: This article deals with the application of a new fuzzy modelling technique that automatically organizes the sets of fuzzy IF–THEN rules in a Hierarchical Collaborative Structure, which makes the fuzzy model interpretable as in the case of the physical model.

TL;DR: The design and implementation of a distributed data acquisition and control system for computerised agricultural management systems that is being developed at Universidade of Tras-os-Montes and Alto Douro, Vila Real is described.
