Grammar-based Encoding of Facades

COMPUTER GRAPHICS FORUM, Issue 4 2010
Simon Haegler
Abstract In this paper we propose a real-time rendering approach for procedural cities. Our first contribution is a new lightweight grammar representation that compactly encodes facade structures and allows fast per-pixel access. We call this grammar F -shade. Our second contribution is a prototype rendering system that renders an urban model from the compact representation directly on the GPU. Our suggested approach explores an interesting connection from procedural modeling to real-time rendering. Evaluating procedural descriptions at render time uses less memory than the generation of intermediate geometry. This enables us to render large urban models directly from GPU memory. [source]

Elastic response spectrum: a historical note

EARTHQUAKE ENGINEERING AND STRUCTURAL DYNAMICS, Issue 1 2007
Anil K. Chopra
Abstract This is the first contribution in a new series of Historical Notes on seminal concepts in earthquake engineering and structural dynamics. It records the origins and early developments (up to the late 1960's) of the elastic response spectrum. Copyright © 2006 John Wiley & Sons, Ltd. [source]

Utilization of tannery solid waste for protease production by Synergistes sp. in solid-state fermentation and partial protease characterization

ENGINEERING IN LIFE SCIENCES (ELECTRONIC), Issue 1 2009
Arumugam Ganesh Kumar
Abstract Synergistes sp. DQ560074 produced a protease in submerged fermentation (SmF) at 400,420,U/mL and in solid-state fermentation (SSF) at 745,755,U/g. The protease, which belongs to the aspartic protease class, was active over a wide range of pH (5,7) and at high temperatures (25,45°C). The protease is stable and active in various polar protic solvents (50%,v/v) like ethanol, isopropanol, n,butanol, in polar aprotic solvents (50%,v/v) like acetonitrile, and in non-polar solvents (50%,v/v) such as ethylacetate and toluene, but not in hydrophilic organic solvents (methyl alcohol and acetone). As far as we know, this is the first contribution to the production of a mesophilic protease with solvent stability in SSF using a proteinaceous solid waste. [source]

Robert Southey, Lord Macaulay and the Standard of Living Controversy

HISTORY, Issue 284 2001
W. A. Speck
The early nineteenth century witnessed gladiatorial contests in print between the contributors to the conservative Quarterly Review and the radical Edinburgh Review. Among the chief protagonists of the two papers were Robert Southey, leading contributor to the Quarterly from its launch in 1809 until 1839, and Thomas Babington Macaulay, whose first contribution to the Edinburgh, on ,Milton', appeared in August 1825, after which he became a mainstay of the periodical. Their ,reviews' were long essays of 10,000 or more words, in which the works purportedly being reviewed were mere pegs on which to hang their own observations. They were generally scathing about publications which took an ideological stance opposite to their own, and sympathetic to those which adopted a similar position to that which they held. Though they frequently made barbed references to each other in their reviews, Southey never reviewed a work by Macaulay, who only once criticized one by his rival. Nevertheless, that particular occasion, in January 1830, was a classic clash of Titans. It demonstrated their fundamental disagreement over the prospects facing society from the initial impact of the industrial revolution. [source]

The Photogrammetric Society: 1952,2001

THE PHOTOGRAMMETRIC RECORD, Issue 100 2002
K. B. Atkinson
A scholarly account of the formative discussions, the founding and the first 20 years of the Photogrammetric Society was published in 1971 and republished in 1974. This present review concentrates on the latter years of the life of the Photogrammetric Society prior to its merger with the Remote Sensing Society in 2001. The authors joined the Photogrammetric Society in 1960 and were conspicuous in its affairs for many years. Although both occupied the Society's presidential chair, they also fulfilled several other roles in its efficient management. Atkinson's first contribution to the Photogrammetric Record was published in 1968 and Newton's in 1971. [source]
