Taking the UK as a case study, this paper describes current energy use and a range of sustainable energy options for the future, including solar power and other renewables. I focus on the area involved in collecting, converting and delivering sustainable energy, looking in particular detail at the potential role of solar power. Britain consumes energy at a rate of about 5000 watts per person, a...

The asymptotic frequency, ω, dependence of the dynamic viscosity of neutral hard sphere colloidal suspensions is shown to be of the form η 0 A(φ)(ωτ P) −1/2 , where A(φ) has been determined as a function of the volume fraction φ, for all concentrations in the fluid range, η 0 is the solvent viscosity and τ P the Péclet time. For a soft potential it is shown that, to leading order in the steepne...

In this paper generalizations of Heilbronn's triangle problem are considered. By using results on the independence number of linear hypergraphs, for xed integers k 3 and any integers n k a o(n6k 4) time deterministic algorithm is given, which nds distributions of n points in the unit square [0; 1]2 such that, simultaneously for j = 3; : : : ; k, the areas of the convex hulls determined by any j...

In this paper, we introduce the vertical set square distance (VSSD) technique that is designed to efficiently and scalably measure the total variation of a set about a fixed point in large datasets. The set can be any projected subspace of any vector space, including oblique subspaces (not just dimensional subspaces). VSSD can determine the closeness of a point to a set of points in a dataset, ...

The velocity field and the instability of the flow in a rotating square duct were investigated. The velocity profiles were obtained for Ekman numbers less than 1/16 by combining a linear Stewartson layer solution, a non-linear Ekman layer solution and a local similarity assumption. The transition of the secondary-flow pattern from one pair of vortices to two pairs of vortices was studied with t...

The Least Square Error (LSE) is widely used method in many engineering and computational problems solution. The LSE method is simple from the “formulation” point of view, offers a simple solution. However, it might lead to wrong or incorrect conclusions, especially if high dimensional or large span data are to be processed or if some variables have significantly smaller influence than the other...
