We define biequivalent planar graphs, which are a generalisation of the uniform polyhedron graphs, as planar graphs made out of two families of equivalent nodes. Such graphs are required to identify polyhedral cages with geometries suitable for artif

Following the discovery of an artificial protein cage with a paradoxical geometry, we extend the concept of homogeneous symmetric congruent equivalent near-miss polyhedral cages, for which all the faces are equivalent, and define bi-homogeneous symme

Following the experimental discovery of several nearly symmetric protein cages, we define the concept of homogeneous symmetric congruent equivalent near-miss polyhedral cages made out of P-gons. We use group theory to parameterize the possible config

Motor current signal analysis is a method to perform on-line monitoring of the condition of electrical motors by examining the spectrum of the residual current of the motor for sidebands around the main frequencies. The interpretation of these spectr

Several spectral analysis algorithms have been developed to identify spectral anomalies. A careful literature analysis is undertaken of sources of nonlinearity through bearing distress and other contacts and rubs within rotor dynamics. Several differ

This report addresses the construction of carbon fibre wing boxes and the problems associated with using carbon fibre sheets rather than individual carbon fibre tapes. In the case that the wing boxes are developable surfaces the lay up of carbon fibr

By using a high-speed camera, researchers at MIT in 2014 where able to recover human speech from videos of minute vibrations of objects in a room. For example, in one experiment a 2,200fps camera was positioned outside a room behind sound-proof glass

Evolution requires self-replication. But, what was the very first self-replicator directly ancestral to all life? The currently favoured RNA World theory assigns this role to RNA alone but suffers from a number of seemingly intractable problems. Inst

We study the long-range electron and energy transfer mediated by a polaron on an $\alpha$-helix polypeptide chain coupled to donor and acceptor molecules at opposite ends of the chain. We show that for specific parameters of the system, an electron i
