Variable Structure Behavioural Controller for Multi-agent Systems
In previous papers authors have considered agents as inertia-less self driven particles and designed a flocking algorithm. Application of this algorithm to agents with considerable inertial characteristics needs a behavioural controller. The controller uses the local information and helps every agent to imitate the desired behaviour as a member of the flocking frame which covers the main is...
متن کاملSpatially Periodic Electromagnetic Force Field For Plasma Confinement and Control
A scientific concept referred to as a “force field” is defined as a short-range, static electromagnetic field that can reflect a charged particle of either sign of charge that approaches at any angle of incidence. A force field is envisioned as consisting of a spatially periodic sequence of magnetic cusps that are electrostatically plugged using applied electrostatic voltage variations similar ...
متن کاملHigh Temperature Shear Horizontal Electromagnetic Acoustic Transducer for Guided Wave Inspection
Guided Wave Testing (GWT) using novel Electromagnetic Acoustic Transducers (EMATs) is proposed for the inspection of large structures operating at high temperatures. To date, high temperature EMATs have been developed only for thickness measurements and they are not suitable for GWT. A pair of water-cooled EMATs capable of exciting and receiving Shear Horizontal (SH₀) waves for GWT with optimal...
متن کاملA Longitudinal Mode Electromagnetic Acoustic Transducer (EMAT) Based on a Permanent Magnet Chain for Pipe Inspection
A new electromagnetic acoustic transducer (EMAT) design, employing a special structure of the permanent magnet chain, is proposed to generate and receive longitudinal guided waves for pipe inspection based on the magnetostriction mechanism. Firstly, a quantitative analysis of the excitation forces shows the influence of the radial component can be ignored. Furthermore, as the axial component of...
متن کاملPartial inspection problem with double sampling designs in multi-stage systems considering cost uncertainty
The nature of input materials is changed as long as the product reaches the consumer in many types of manufacturing processes. In designing and improving multi-stage systems, the study of the steps separately may not lead to the greatest possible improvement in the whole system, therefore the study of inputs and outputs of each stage can be effective in improving the output quality characterist...
