Oil spill accidents from ship or oil platform cause damage to marine and coastal environment and ecosystems. To monitor such spill events from space, fully polarimetric (Pol-SAR) synthetic aperture radar (SAR) has been greatly used in improving oil spill observation. Aiming to promote ocean oil spill classification accuracy, we developed a new oil spill identification method by combining multip...

ion In this project, a neural network-driven digital image processing method is studied to identify and classify the oil paintings. Traditionally, this authentication work is often entrusted to human experts, whereas it is becoming harder with even more forgeries emerging. Based on the previously contributions of digital image processing and neural network methods, I believe the combination wil...

Context. Among optical stellar interferometers, the CHARA Array located at Mt Wilson in California offers the potential of very long baselines (up to 330 m) and the prospect of coupling multiple beam combiners. This paper presents the principle and the measured performance of VEGA, Visible spEctroGraph and polArimeter installed in September 2007 at the coherent focus of the array. Aims. With 0....

there is no agreement among different economic schools about role of monetary policy in stabilization policy. new classic by means of rational expectations show that only unanticipated monetary policy influences upon real variables. how ever new keynsian by means of rational expectations shows that anticipated monetary policy influences real ariables too. the present article investigates above ...

In this paper the relationships between crude oil and refined product prices are investigated in a multivariate framework. This allows us to test several (partly competing) assumptions of earlier studies. In particular, we find that the crude oil price is weakly exogenous and that the spread is constant in some but not all relationships. Moreover, the multivariate analysis shows that the link b...

The terms of trade debate initiated by Raul Prebisch and Hans Singer over 60 years ago continues to this day and is unlikely to be resolved soon. However, even if Prebisch and Singer are right and the terms of trade of countries exporting primary products are falling, to suggest that these countries should diversify away from the production of mineral commodities and other primary products, as ...

We explore the implications of migrants’self-selection for the determination of immigration policy in a simple model where incentives and resources to migrate vary with skills. We show how self-selection determines the response of potential migrants to immigration policy changes, which is crucial for predicting the e¤ects of such policy in the receiving country. For example, restricting immigra...
