Global sea-level contribution from Arctic land ice: 1971-2017

The Arctic Monitoring and Assessment Program (AMAP 2017) report identifies the Arctic as the largest regional source of land ice to global sea-level rise in the 2003-2014 period. Yet, this contextualization ignores the longer perspective from in situ records of glacier mass balance. Here, using 17 (>55°N latitude) glacier and ice cap mass...

Kraichnan-Leith-Batchelor similarity theory and two-dimensional inverse cascades

We study the scaling properties and Kraichnan-Leith-Batchelor (KLB) theory of forced inverse cascades in generalized two-dimensional (2D) fluids ($\alpha$-turbulence models) simulated at resolution $8192^2$. We consider $\alpha=1$ (surface quasigeostrophic flow), $\alpha=2$ (2D vorticity dynamics) and $\alpha=3$. The forcing scale is well...

Distribution and modal split models for freight transport in the Netherlands

The Netherlands has a tradition of using mathematical models in policy and decision making in transport (and other sectors). In an effort to improve the information provided to policy makers and to maximise the added value of the existing instruments and available knowledge and data, the Dutch Ministry of Infrastructure and the Environment...

Strategic Planning & Urban Projects: Responses to Globalization from 15 cities

This book draws upon the ongoing research activities of agiobal network of urban researchers - the IBIS network. The IBIS network is a European Community funded network of four European universities and South American universities. The network involves postgraduate student exchanges and the development of research programmes in urban planning,...

Contemporary Urban Strategies and Urban Design in Developing Countries: A critical Review

The performance of fans in hovercraft: a method of reducing experimental results

A new method for reducing data on hovercraft fan performance is proposed which is expected to lead to a simplification of model and flight test procedures. The method is shown to be theoretically justified, and supporting experimental evidence is provided from models with both solid and flexible duet geometry.
