Object localisation using active whiskers on underwater autonomous walking robot (2011)
Book Chapter
A low-cost, biologically inspired underwater walking robot (see Fig. 1) has been designed and built to covertly explore the seabed and to determine properties of submerged objects in obscure and inaccessible underwater locations. This paper focuses o... Read More about Object localisation using active whiskers on underwater autonomous walking robot.
On polymorphic logical gates in subexcitable chemical medium (2011)
Journal Article
In a subexcitable light-sensitive Belousov-Zhabotinsky (BZ) chemical medium an asymmetric disturbance causes the formation of localized traveling wave-fragments. Under the right conditions these wave-fragments can conserve their shape and velocity ve... Read More about On polymorphic logical gates in subexcitable chemical medium.
Aluminium electrodes effect the operation of titanium oxide sol-gel memristors (2011)
Preprint / Working Paper
By a comparison between memristors made with aluminium and gold electrodes, this letter demonstrates that aluminium electrodes are an essential component of the TiO$_2$ sol-gel flexible memristor . Both slow varying `analogue' and sudden switching `d... Read More about Aluminium electrodes effect the operation of titanium oxide sol-gel memristors.
On attraction of slime mould Physarum polycephalum to plants with sedative properties (2011)
Journal Article
A plasmodium of acellular slime mould Physarum polycephalum is a large single cell with many nuclei. Presented to a configuration of attracting and repelling stimuli a plasmodium optimizes its growth pattern and spans the attractants, while avoiding...

Cellular automaton supercolliders (2011)
Journal Article
Gliders in one-dimensional cellular automata are compact groups of non-quiescent and non-ether patterns (ether represents a periodic background) translating along automaton lattice. They are cellular automaton analogous of localizations or quasi-loca... Read More about Cellular automaton supercolliders.
Unsupervised sub-segmentation for pigmented skin lesions (2012)
Journal Article
Background: Early identification of malignant melanoma with the surgical removal of thin lesions is the most effective treatment for skin cancers. A computer-aided diagnostic system assists to improve the diagnostic accuracy, where segmenting lesion... Read More about Unsupervised sub-segmentation for pigmented skin lesions.
Computer scientists build cellular automaton supercollider (2011)
Journal Article
A virtual accelerator that smashes together glider-like particles inside a cellular automaton can perform computations, say researchers.
Gathering and presenting social feedback to change domestic electricity consumption (2011)
Presentation / Conference Contribution
This paper describes the CHARM Energy Study in which mobile technology is used to study the impact of social group feedback on household energy consumption. We describe the background and rationale behind the study, the technology which supports th... Read More about Gathering and presenting social feedback to change domestic electricity consumption.
The overshoot phenomenon as a function of internal resistance in microbial fuel cells (2011)
Journal Article
A method for assessing the performance of microbial fuel cells (MFCs) is the polarisation sweep where different external resistances are applied at set intervals (sample rates). The resulting power curves often exhibit an overshoot where both power a... Read More about The overshoot phenomenon as a function of internal resistance in microbial fuel cells.
Computational modalities of Belousov-Zhabotinsky encapsulated vesicles (2011)
Journal Article
We present both simulated and partial empirical evidences for the computational utility of many connected vesicle analogues of an encapsulated nonlinear chemical processing medium. By connecting small vesicles containing a solution of sub-excitable B... Read More about Computational modalities of Belousov-Zhabotinsky encapsulated vesicles.
Towards arithmetic circuits in sub-excitable chemical media (2011)
Journal Article
A sub-excitable Belousov-Zhabotinsky medium exhibits localized travelling excitations (in contrast to an excitable medium exhibiting target or spiral waves). Initially assymetric perturbations give birth to excitation wave-fragments. The shape and ve... Read More about Towards arithmetic circuits in sub-excitable chemical media.
Vesicle computers: Approximating a Voronoi diagram using Voronoi automata (2011)
Journal Article
Irregular arrangements of vesicles filled with excitable and precipitating chemical systems are imitated by Voronoi automata - finite-state machines defined on a planar Voronoi diagram. Every Voronoi cell takes four states: resting, excited, refracto... Read More about Vesicle computers: Approximating a Voronoi diagram using Voronoi automata.

Evolving cell array configurations using CGP (2011)
Presentation / Conference Contribution
A cell array is a proposed type of custom FPGA, where digital circuits can be formed from interconnected configurable cells. In this paper we have presented a means by which CGP might be adapted to evolve configurations of a proposed cell array. As p... Read More about Evolving cell array configurations using CGP.
Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks (2011)
Journal Article
Excitation waves on a subexcitable Belousov-Zhabotinsky (BZ) substrate can be manipulated by chemical variations in the substrate and by interactions with other waves. Symbolic assignment and interpretation of wave dynamics can be used to perform log... Read More about Logical and arithmetic circuits in Belousov-Zhabotinsky encapsulated disks.
Evolving spiking networks with variable memristors (2011)
Presentation / Conference Contribution
Towards evolving spiking networks with memristive synapses (2011)
Presentation / Conference Contribution
This paper presents a spiking neuro-evolutionary system which implements memristors as neuromodulatory connections, ie whose weights can vary during a trial. The evolutionary design process exploits parameter self-adaptation and a constructionist app... Read More about Towards evolving spiking networks with memristive synapses.
