This paper presents a new forward-in-time advection method for nearly incompressible ow, MU, and its application to an adaptive multilevel ow solver for atmospheric ows. MU is a modi cation of Leonard et al.'s (1993) UTOPIA scheme. MU, like UTOPIA, is based on third-order accurate semiLagrangian multidimensional upwinding for constant velocity ows. For varying velocity elds, MU is a second-orde...

Jill Craigie's controversial BBC documentary, Who ?re the vandals?, brought into focus many of the inherent shortcomings of so much of new mass houslng in the last twenty years. Miss Craigie pinpointed a number of doubts about housing policy which have lurked just beneath the surface in the minds of many of the architects and I. Planners working within its present framework. 'Build up, not out'...

Recently obtained Mars Orbiter Laser Altimeter (MOLA) topography has permitted a new assessment of the morphology, structure, and history of Utopia Planitia. The new topographic data convincingly demonstrate that the Utopia region is an impact basin, as originally proposed by McGill [1989], whose major topographic expression is a circular, 1–3 km deep depression 3200 km in diameter. Utopia Basi...

MOTIVATION In recent years, the gulf between the mass of accumulating-research data and the massive literature describing and analyzing those data has widened. The need for intelligent tools to bridge this gap, to rescue the knowledge being systematically isolated in literature and data silos, is now widely acknowledged. RESULTS To this end, we have developed Utopia Documents, a novel PDF rea...
