This paper looks at how the concept of reusability has gained currency in e-learning. Initial attention was focused on reuse of content, but recently attention has focused on reusable software tools and reusable activity structures. The former has led to the proposal of service-oriented architectures, and the latter has seen the development of the Learning(More)
In trying to mimic biological functions of the brain, artificial neural network (ANN) research has, out of computational necessity, made a number of assumptions. Firstly, it is assumed that the complexity of biological processes can be usefully replicated artificially by abstracting a relatively few key or essential characteristics from the biological(More)
The Harmony Search Algorithm (HSA) is a recently constructed algorithm that is based on the improvisation process that musicians often demonstrate in performances [1],[2]. In the HSA each musician plays a note in an effort to find the best harmony with his/her fellow musicians. In the context of Computer Science, this improvisation process corresponds to a(More)
An evolvable analogue electronic artificial cochlea has become a practical proposition with the recent development of dynamically configurable and reconfigurable Field Programmable Analogue Arrays (FPAA). The authors describe a proof-of-concept system based on the Anadigm® FPAA that implements a four-channel evolvable cochlea on one device. A genetic(More)

One of the core steps of the assembly of wind turbines is the assembly of the bearings on the wind turbine hub. The hub can contain up to 128 bolt connections to install the bearing blades: nuts need to be precisely tightened to ensure a uniformly distributed clamping force as well as avoiding assembly errors, e.g. nut misalignments. The bolt-nut connection(More)
There has been considerable recent activity in the area of Spiking Neural P systems and notably, their extension by the simulation of astrocytes. Work in this area has focused on intracellular interaction between astrocytes and neurons. This paper further extends this idea by considering extracellular communication between astrocytes, in particular linking(More)
