Completing the EU Customs Union. The Effects of Trade Procedure Harmonization

A main component of customs unions is a common trade policy on imports from non-member countries. Trade policy covers both tariff and non-tariff barriers like trade procedures. We argue that since trade procedures vary markedly across EU countries, the EU is not, strictly speaking, a customs union. To illustrate this, we estimate the impact of trade procedures on exports from non-EU countries and

Object characterization with refractometric digital holography

We demonstrate a Digital Holographic method where two different substances in a blend can be discerned. The method requires only one set of exposures and one reconstruction in the plane of focus. The large scale phase variation of the phase image is unwrapped by Flynn’s discontinuity algorithm to reveal which regions in the sample the phase has decreased or increased upon transmission of the illumi

An Opportunistic Backoff Scheme for Dense IEEE 802.11 WLANs

In dense deployments, the performance of IEEE 802.11 Wireless Local Area Networks (WLANs) depends on the development of efficient contention resolution mechanisms since the collision probability can be high even with low number of users with the current 802.11 MAC mechanism. Also, the current 802.11 MAC is not opportunistic in the sense that it does not consider channel quality and traffic load of
