Investment appraisal using quantitative risk analysis

Investment appraisal concerned with investments in fire safety systems is discussed. Particular attention is directed at evaluating, in terms of the Bayesian decision theory, the risk reduction that investment in a fire safety system involves. It is shown how the monetary value of the change from a building design without any specific fire protection system to one including such a system can be estimated by use of quantitative risk analysis, the results of which are expressed in terms of a Risk-adjusted net present value. This represents the intrinsic monetary value of investing in the fire safety system. The method suggested is exemplified by a case study performed in an Avesta Sheffield factory.     

Investment risk analysis with a simple utility function

This study suggests an approach to investment risk analysis which provides a useful complement to more detailed analyses. The analyst specifies an appropriate distribution of cash flows and associated utility function from one of the four models suggested. Next, the risk adjusted present value of the investment stream is calculated using the simplified procedure outlined in the paper. Sensitivity analysis is then performed on the results to determine whether a more extensive analysis of the decision maker's risk preferences is called for.

The genesis of Jan Steens painting “As the old ones sing, so the young ones pipe” from the Gemäldegalerie Berlin

In collaboration with the research reactor of the Helmholtz-Zentrum Berlin für Materialien und Energie, the Gemäldegalerie Berlin is the only institute worldwide, which systematically employs the method of Neutron-Activation-Autoradiography to analyze paintings and painting techniques. To date more than 70 paintings were investigated with this effective, non-destructive, and exceptional method. It allows the visualization of structures and layers beneath the top surface and, in addition, enables the identification of elements contained in the pigments. The instrument B8 at the research reactor BER II is dedicated to this research.Jan Steen is one of the prolific artists from the 17th century. Like other artists from that time he produced several versions of one specific topic during life-time. The topic “As the old ones sing, so the young ones pipe” was painted by Jan Steen in 13 versions. The painting from the Gemäldegalerie is an exception in this series as it differs in style and content from the other oeuvres. The question arises: why did the artist deviate from his usual scheme?The possible answer is provided by X-ray images and neutron autoradiographs made of the painting, allowing insight into hidden paint layers and, therefore, in the genesis of the painting. Jan Steen did not simply change the composition of the room and the figures. He originally intended an altogether different topic. Assumedly it was supposed to be a so-called merry company, located in a generous, stately room. Many pieces of this sophisticated ambiance have been eliminated from the version visible today; others were modified and integrated into the composition of the new painting. Thus, Jan Steen commenced the topic “As the old ones sing, so the young ones pipe” from a different context.     

Comment on "the use of real or complex coupling coefficients for lossy piezoelectric materials"

We show that the claims of a recent paper on coupling which states that the complex coupling has mathematical difficulties and is inconsistent with a specific experiment are incorrect.
