Lecturer(1) "Computation and communication on nanometer scales"
Speaker Dr. Ferdinand Peper

Abstract In this presentation we discuss nanocomputer architectures based on asynchronous cellular automata, token-based computing, reversible asynchronous circuits, and communication between agents on molecular scales.
Lecturer(2) "REACTION-DIFFUSION COMPUTERS: FROM CELLULAR AUTOMATA TO WETWARE"
Speaker Prof. Andrew Adamatzky

Abstract We introduce a hot topic of novel and emerging computing paradigms and architectures --- computation realised by travelling waves in reaction-diffusion media. A reaction-diffusion computer is a massively parallel computing device, where the micro-volumes of the chemical medium act as elementary few-bit processors, and chemical species diffuse and react in parallel. In the reaction-diffusion computer both the data and the results of the computation are encoded as concentration profiles of the reagents, or local disturbances of concentrations, whilst the computation per se is performed via the spreading and interaction of waves caused by the local disturbances. This presentation brings together results of a decade-long study into designing experimental and simulated prototypes of reaction-diffusion computing devices for image processing, path planning, robot navigation, computational geometry, logics and artificial intelligence.
Lecturer(3) "Computation and communication on nanometer scales"
Speaker Dr. Ben De Lacy Costello
(Faculty of Applied Sciences, University of West England, Bristol, United Kingdom)
Abstract on-linear chemistry and non-classical computation share more than just a prefix: these two fields of science flourished on fertile soil - the analysis of emerging phenomenon of pattern formation, dissipative structures, somewhat unpredictable space-time dynamics and, basically, unconventional views on existing scientific norms, laws and rules. I informally introduce the basic concepts of self-organization and controllability in spatially distributed chemical systems, and consider examples of excitable, oscillating, precipitating chemical systems. I also informally discuss previously established results in the implementation of basic computational operations in chemical systems: mass-flow chemical gates, logics of excitation impulses in geometrically constrained medium, chemical diodes, image processing, dynamical memory. We analyse how well reaction-diffusion computers are positioned amongst other types of novel and emerging computing devices and paradigms.
