Computer Science and Electronic Engineering Facebook page has launched a
monthly competition for contributors to the page. At the end of each month 3
unique names will be drawn at random. The prizes will be given in the order of
the names drawn out of the hat. First prize for the first name, second prize for
the second name and third prize for the third name.

The third Computer science and Electronic Engineering Conference (CEEC) will
be taking place on 13-14 July 2011 at the University of Essex.
CEEC is an ideal venue for postgraduate researchers in the disciplines of
mathematics, computer science, engineering, physics, biology and finance to meet
fellow researchers in their field. The conference, organised by a group of
research students from the University of Essex, aims to create a forum in which
the participants can work together, discuss, compare and debate different
innovative ideas and solutions.
CEEC aims to present the current and recent works of postgraduate researchers
and provides them with the following opportunities:
Postgraduate researchers are hereby invited to submit papers related to their
current and recent research. The conference will be hosted by the School of
Computer Science and Electronic Engineering.
See the CEEC website

Riccardo Poli, Mathew Salvaris and Caterina Cinel, Evolution of a
Brain-Computer Interface Mouse via Genetic Programming, European
Conference on Genetic Programming 2011.
Abstract - We propose the use of genetic programming as a means to evolve
brain-computer interfaces for mouse control. Our objective is to synthesise
complete systems, which analyse electroencephalographic signals and directly
transform them into pointer movements, almost from scratch, the only input
provided by us in the process being the set of visual stimuli to be used to
generate recognisable brain activity.
Experimental results with our GP approach are very promising and compare
favourably with those produced by support vector machines.
Mario Graff and Riccardo Poli, Performance Models for Evolutionary
Program Induction based on Problem Difficulty Indicators, European
Conference on Genetic Programming 2011.
Abstract - Most theoretical models of evolutionary algorithms are difficult
to apply to realistic situations. In this paper, two models of evolutionary
program-induction algorithms (EPAs) are proposed which overcome this limitation.
We test our approach with two important classes of problems --- symbolic
regression and Boolean function induction --- and a variety of EPAs including:
different versions of genetic programming, gene expression programming,
stochastic iterated hill climbing in program space and one version of Cartesian
genetic programming. We compare the proposed models against a practical model of
EPAs we previously developed and find that in most cases the new models are
simpler and produce better predictions. A great deal can also be learnt about an
EPA via a simple inspection of our new models. E.g., it is possible
to infer which characteristics make a problem difficult or easy for the EPA.

Synthesis of a Trajectory Integrator for an Analogue Brain-Computer Interface
Mouse, European Conference on the Applications of Evolutionary
Abstract - Recently significant steps have been made towards effective
EEG-based brain-computer interfaces for mouse control. A major obstacle in this
line of research, however, is the integration of the noisy and contradictory
information provided at each time step by the signal processing systems into a
coherent and precise trajectory for the mouse pointer. In this paper we attack
this difficult problem using genetic programming, obtaining extremely promising

Kick-drum signal acquisition, isolation and reinforcement optimization
in live sound, 130th Convention of the Audio Engineering Society,
London, 13-16 May 2011.
Abstract - A critical requirement for popular music in live-sound
applications is the achievement of a robust kick-drum sound presented to the
audience and the drummer while simultaneously achieving a workable degree of
acoustic isolation for other on-stage musicians. Routinely a transparent wall is
placed in parallel to the kick-drum heads to attenuate sound from the drummer’s
monitor loudspeakers, although this can cause sound quality impairment from
comb-filter interference. Practical optimization techniques are explored,
embracing microphone selection and placement (including multiple microphones in
combination), isolation-wall location, drum-monitor electronic delay and echo
cancellation. A system analysis is presented augmented by real-world
measurements and relevant simulations using a bespoke Finite-Difference
Time-Domain (FDTD) algorithm.
