Recent improvements in growth methodologies have decreased the grain sizes and thicknesses of polycrystalline diamond films to the nanometer range, while also increasing the film uniformity and growth rate and preserving the outstanding mechanical properties of diamond. This is rendering such films more technologically and commercially viable. Ultrananocrystalline diamond (UNCD) are the thinnes...

A principal-agent (P-A) model is used to analyse the effect of environmental performance indicators (EPI) on environmental risk sharing within the firm. To achieve due diligence, the principal (top management), having to use imperfect performance indicators and fearing penalties for environmental damages, wants to avoid environmental harm and induce the agent (employee manipulating hazardous ma...

Perfect spatial/temporal knowledge of the ocean environment is rarely available for evaluation of sonar performance. Instead, performance prediction is often done with acoustic models assuming idealized inputs. The current capability of many such models is superb; realistic inputs, however, often are not available, and this is the central focus of the present paper. The prediction of sonar perf...
