Cartesian genetic programming for memristive logic circuits (2012)
Presentation / Conference Contribution

In this paper memristive logic circuits are evolved using Cartesian Genetic Programming. Graphs comprised of implication logic (IMP) nodes are compared to more ubiquitous NAND circuitry on a number of logic circuit problems and a robotic control task...

Tactile SLAM with a biomimetic whiskered robot (2012)
Presentation / Conference Contribution

Future robots may need to navigate where visual sensors fail. Touch sensors provide an alternative modality, largely unexplored in the context of robotic map building. We present the first results in grid based simultaneous localisation and mapping (... Read More about Tactile SLAM with a biomimetic whiskered robot.

Towards an intelligent distributed conveyor (2012)
Journal Article

Manipulation, orientation and handling of components, subparts and finished products is an essential element of any industrial process, which attracts substantial portion of resources and infrastructure. A classic manipulation, e.g. robot arms, is no... Read More about Towards an intelligent distributed conveyor.

Brain-inspired Bayesian perception for biomimetic robot touch (2012)
Presentation / Conference Contribution

Studies of decision making in animals suggest a neural mechanism of evidence accumulation for competing percepts according to Bayesian sequential analysis. This model of perception is embodied in a biomimetic tactile sensing robot based on the ro... Read More about Brain-inspired Bayesian perception for biomimetic robot touch.

The missing magnetic flux in the HP memristor found (2011)
Preprint / Working Paper

Ever since real-world two terminal memristor devices were created, detractors have derided them as not `true' Chua memristors because there is no magnetic flux in the system. This report shows that the flux is present and equal to the magnetic flux o... Read More about The missing magnetic flux in the HP memristor found.

Towards tactile sensing applied to underwater autonomous vehicles for near shore survey and de-mining (2012)
Journal Article

Artificial tactile whisker sensors demonstrate an approach to localisation that is robust to harsh environmental disturbances, endowing autonomous systems with the ability to operate effectively in confined, noisy and visually occluded spaces, such a...

Dynamic deflectometry: A novel approach for the on-line reconstruction of specular freeform surfaces (2012)
Journal Article

The dynamic inspection and reverse engineering of specular freeform surfaces is a challenge so far largely unsolved. Products produced in high quantities in industrial environments are still inspected manually which is labour intensive, expensive, mo...

Computing with liquid crystal fingers: Models of geometric and logical computation (2011)
Journal Article

When a voltage is applied across a thin layer of cholesteric liquid crystal, fingers of cholesteric alignment can form and propagate in the layer. In computer simulation, based on experimental laboratory results, we demonstrate that these cholesteric...

Comparison of ant-inspired gatherer allocation approaches using memristor-based environmental models (2011)
Presentation / Conference Contribution

Memristors are used to compare three gathering techniques in an already-mapped environment where resource locations are known. The All Site model, which apportions gatherers based on the modeled memristance of that path, proves to be good at increasi...

Psychologically inspired dimensionality reduction for 2D and 3D Face Recognition (2011)
Presentation / Conference Contribution

We present a number of related novel methods for reducing the dimensionality of data for the purposes of 2D and 3D face recognition. Results from psychology show that humans are capable of very good recognition of low resolution images and caricature...

Multi-scale integration of slope data on an irregular mesh (2011)
Presentation / Conference Contribution

Memristive excitable cellular automata (2011)
Journal Article

The memristor is a device whose resistance changes depending on the polarity and magnitude of a voltage applied to the device's terminals. We design a minimalistic model of a regular network of memristors using structurally-dynamic cellular automata.... Read More about Memristive excitable cellular automata.

Biology and computing (2011)
Presentation / Conference Contribution

Memristors, the recently discovered 4th fundamental circuit element, have been used as models for biological components, such as neurons. It may be that neurons are memristors, rather than just conveniently modeled by them. This presentation covers r... Read More about Biology and computing.

Biomimetic vibrissal sensing for robots (2011)
Journal Article

Active vibrissal touch can be used to replace or to supplement sensory systems such as computer vision and, therefore, improve the sensory capacity of mobile robots. This paper describes how arrays of whisker-like touch sensors have been incorporated... Read More about Biomimetic vibrissal sensing for robots.

On computing in fine-grained compartmentalised Belousov-Zhabotinsky medium (2011)
Journal Article

We introduce results of computer experiments on information processing in a hexagonal array of vesicles filled with Belousov-Zhabotinsky (BZ) solution in a sub-excitable mode. We represent values of Boolean variables by excitation wave-fragments and... Read More about On computing in fine-grained compartmentalised Belousov-Zhabotinsky medium.

Twins 3D face recognition challenge (2011)
Presentation / Conference Contribution

Existing 3D face recognition algorithms have achieved high enough performances against public datasets like FRGC v2, that it is difficult to achieve further significant increases in recognition performance. However, the 3D TEC dataset is a more chall... Read More about Twins 3D face recognition challenge.
