"Multi-robot Deconflicted Path Planning for Wheeled Mobile Robot Through Fuzzy Logic Controller"

• Xueliang Cheng
• Zhengyi Jiang
• Hanlin Niu
• Keir Groves
• Simon Watson
• Nobuto Matsuhira
• Barry Lennox
• Hajime Asama

In this paper we propose a multi-robot path planning algorithm that integrates a Vector Field Histogram (VFH) algorithm and fuzzy logic controller inspired by International Regulations for Preventing Collisions at Sea (COLREGs) traffic rules with a collision area membership function that identifies suitable traffic procedures for each robot to t…

"The Cascading Pebble Divertor for the Spherical Tokamak Power Plant"

• A.Bond
• S. Davis
• M.Harte
• R.Watson

The design of a power plant based on the spherical tokamak (ST) is being developed in order to explore its potential advantages. The plasma is operated in a double null configuration, forming both an upper and lower divertor. In order to accommodate the high erosion rates and heat fluxes developed in the divertors, a system based on a cascading flo…

"Studies of heating and impurity transport in the plasma boundary of tokamaks"

• G. M. Mccracken
• U. Samm

Impurities in fusion plasmas lead to a loss of reactivity by radiation and fuel dilution. 1 The impurity concentration in the plasma is determined both by the production rate and transport in the plasma, particularly the transport in the boundary layer. 1'2 In this layer impurities, usually starting as cold atoms or molecules, are ionised and heate…
