This paper gives an overview of three topics related to sound insulation in buildings. The first project included laboratory and field measurements of sound insulation against aircraft noise. As well as various technical papers, the project produced software to help in the design of adequate sound insulation. In a second project, re-analysis of survey results allowed the development of a ration...

I remember that as a student, when I wanted to find papers about new developments in disease management, I needed to consult what looked like a set of encyclopaedias—the MEDLINE / Index Medicus. There followed a search in the medical library for hard copies of overseas medical journals. What a tedious job it was! Thanks to the invention of computers and evolvement of this cyber world, I can now...

We have performed FTIR transmission microspectroscopy on graphene oxide papers oriented with the nominal lattice planes parallel to the infrared optical axis. By polarising the IR light for samples of this geometry, spectral contributions of oriented oxide species are isolated from broad convoluted bands. Analysing the data alongside previous works, including experiments where samples were pert...

We view achieving a particular correlated equilibrium distribution for a normal form game as an implementation problem. We show, using a parametric version of the two-person Chicken game and a wide class of correlated equilibrium distributions, that a social choice function that chooses a particular correlated equilibrium distribution from this class does not satisfy the Maskin monotonicity con...

Let G be a semisimple Lie group and € <G a lattice. Following Sarnak [25], a subgroup  of € is called thin if  has infinite index in € , but is Zariski dense. Since it is straightforward to exhibit free subgroups of lattices that are Zariski dense, we shall, in addition insist that a thin group  is finitely generated and does not decompose as a free product. There has been a good deal of int...

The first two papers of this series gave evidence for the chemical changes undergone by 3,4-benzpyrene in the tissues of the mouse. A number of metabolites were described and provisionally named, Xl, X2, F1, and F2. Of these, the chemical nature is known only of F2, this being, in the case of mice, 8-hydroxybenzpyrene. Furthermore, it was shown that the X-derivatives are the first formed. It ha...

Commentary V alue judgments lurk beneath the surface in any study of health inequalities; analysts ought to understand them, make them explicit, and present results transparently to poli-cymakers so that they, rather than analysts, decide which set of value judgments should be invoked. that is the key message of the paper " Lies, Damned Lies, and Health Inequality measurements " 1 Kjellsson et ...

In this discussion paper, we propose to employ chatbots as a user-friendly interface for open data published by organizations, specifically focusing on public administrations. Open data are especially useful in e-Government initiatives but their exploitation is currently hampered to end users by the lack of user-friendly access methods. On the other hand, current UX in social networks have made...

This is the first of a series of papers devoted to the group-theoretical analysis of the conditions which must be satisfied for a configuration of intersecting M5-branes to be supersymmetric. In this paper we treat the case of static branes. We start by associating (a maximal torus of) a different subgroup of Spin 10 with each of the equivalence classes of supersymmetric configurations of two M...
