We discuss the problem of computing the volume of a convex body K in R. We review worst-case results which show that it is hard to deterministically approximate voln K and randomised approximation algorithms which show that with randomisation one can approximate very nicely. We then provide some applications of this latter result. •Supported by NATO grant RG0088/89 t Supported by NSF grant CCR-...

In response to this call, a joint Workshop was organised at short notice, bringing together international experts from Russia, the NATO countries and other relevant nations to discuss the social and psychological implications of the new terrorism. The workshop was held at NATO Headquarters between the 25 and 27th March 2002, and generated interest, activity, enthusiasm and no shortage of questi...

This review is written for the NATO lecture series: NATO RTA “Survival at Sea for Mariners, Aviators and Personnel Involved in Search and Rescue”. It provides a brief historical perspective, updated scientific information on the phenomenon, susceptibility and management of seasickness. It is designed to provide the latest data on seasickness for all those who earn their living working on or fly...

As part of its ongoing effort to encourage rapid prototyping within NATO, the Allied Command Transformation Modelling and Simulation Section is actively involved in modelling and simulating at the multinational political/military level. Experimentation with multinational political concepts and at the military strategic level is inherently complicated and sensitive. Simulation can be used to not...

In 2011 NATO launched its Smart Defense Initiative which was intended to provide greater security with fewer resources combined with higher level of coordination and coherence among allies and partners. The importance of this initiative was once again highlighted at the 2012 NATO Summit in Chicago which welcomed national and transnational efforts to “develop, acquire and maintain the capabiliti...

IST-110 is the North Atlantic Treaty Organization (NATO) Research Task Group on visualization for analysis. The Group works to promote the research and deployment of visual analytics techniques among the NATO member nations and partner nations. The Group promotes collaboration and research in a broad range of NATO application areas. This poster describes an exploration of the Royal Netherlands ...

We evaluate and compare the gravitational wave and density perturbation contributions to the cosmic microwave background radiation, on the basis of the same power law inflationary model. The inflation to radiation transition is treated in this paper as instantaneous, but a model is constructed to allow for a smooth transition from the radiation to the matter dominated eras. The equations are nu...

We apply the method of conical singularities to calculate the tree-level entropy and its one-loop quantum corrections for a charged Kerr black hole. The Euclidean geometry for the Kerr-Newman metric is considered. We show that for an arbitrary periodization in Euclidean space there exists a conical singularity at the horizon. Its δ-function like curvatures are calculated and are shown to behave...

These are notes for lectures delivered at the NATO ASI on Dynamics in Leiden, The Netherlands, in July 1998. The quantum kinetic theory for noninteracting electrons in a disordered solid is introduced and discussed. We first use many-body theory to derive the quantum Boltz-mann equation that describes transport and time correlation functions in this system. Particular attention is paid to the c...

Application of telemedicine systems to cover distant geographical areas has increased recently. However, the potential usefulness of similar systems for creation of national networks does not seem to be widely appreciated. The article describes the "Virtual Health Care Knowledge Center in Georgia" project. Its aim was the set up of an online integrated web-based platform to provide remote medic...
