VERY HIGH RESOLUTION INTERPOLATED CLIMATE SURFACES FOR GLOBAL LAND AREAS

by Robert J. Hijmans, Susan E. Cameron, Juan L. Parra, Peter G. Jones , Andy Jarvis , 2005
"... We developed interpolated climate surfaces for global land areas (excluding Antarctica) at a spatial resolution of 30 arc s (often referred to as 1-km spatial resolution). The climate elements considered were monthly precipitation and mean, minimum, and maximum temperature. Input data were gathered ..."

Representing twentieth century space-time climate variability, part 1: development of a 1961-90 mean monthly terrestrial climatology

by Mark New, Mike Hulme, Phil Jones - Journal of Climate , 1999
"... The construction of a 0.58 lat 3 0.58 long surface climatology of global land areas, excluding Antarctica, is described. The climatology represents the period 1961–90 and comprises a suite of nine variables: precipitation, wet-day frequency, mean temperature, diurnal temperature range, vapor pressur ..."

Efficient Variants of the ICP Algorithm

by Szymon Rusinkiewicz, Marc Levoy - INTERNATIONAL CONFERENCE ON 3-D DIGITAL IMAGING AND MODELING , 2001
"... The ICP (Iterative Closest Point) algorithm is widely used for geometric alignment of three-dimensional models when an initial estimate of the relative pose is known. Many variants of ICP have been proposed, affecting all phases of the algorithm from the selection and matching of points to the minim ..."

to the minimization strategy. We enumerate and classify many of these variants, and evaluate their effect on the speed with which the correct alignment is reached. In order to improve convergence for nearly-flat meshes with small features, such as inscribed surfaces, we introduce a new variant based on uniform

A New Point Matching Algorithm for Non-Rigid Registration

by Haili Chui, Anand Rangarajan , 2002
"... Feature-based methods for non-rigid registration frequently encounter the correspondence problem. Regardless of whether points, lines, curves or surface parameterizations are used, feature-based non-rigid matching requires us to automatically solve for correspondences between two sets of features. I ..."

Pyramidal parametrics

by Lance Williams - Computer Graphics (SIGGRAPH ’83 Proceedings , 1983
"... The mapping of images onto surfaces may substantially increase the realism and information content of computer-generated imagery. The projection of a flat source image onto a curved surface may involve sampling difficulties, however, which are compounded as the view of the surface changes. As the pr ..."

PLATE FLATNESS METER BASED ON

by Moire Fringes, Jiro Matsuo, Toshiyuki Matsumi, Kouichi Kitamura, Nagoya Works Electronics R, D Labratories
"... A plate flatness meter based on the laser moire method was developed. A large grating is installed above a plate transfer line, a laser beam is dire-cted through a concave lens onto the plate on the transfer line. Moire fringes that conform to the surface profile of the plate are formed on the pl-at ..."

a vertical flat plate

by Rebhi A. Damseh, A. J. Chamkha
"... Abstract: The effect of heat and mass transfer on transient laminar free convection flows for saline water over a vertical flat surface is studied. The non-Boussinesq equation to approximate temperature variations with density in buoyancy term is applied. The governing equations are written in their ..."

Effect of Porous Surface on the Flat Plate Self-Noise

by Youngmin Bae, Ye Eun Jeong, Young J. Moon
"... In this study, the effect of porous surface on the turbulent noise generated by a blunt trailing-edge of a flat plate is investigated. The three-dimensional turbulent flow over the flat plate (Rec=1.3×105 and M=0.06) is computed by incompressible large eddy simulation (LES) based on the volume-avera ..."

Recovering surface layout from an image

by Derek Hoiem, Alexei A. Efros, Martial Hebert - In IJCV , 2007
"... Humans have an amazing ability to instantly grasp the overall 3D structure of a scene – ground orientation, relative positions of major landmarks, etc – even from a single image. This ability is completely missing in most popular recognition algorithms, which pretend that the world is flat and/or vi ..."

Flat Plate collector – An Experimental Study

by A. V. Rabadiya, Ravindra Kirar, S. V. Ballar
"... Solar energy will be more relevant for developing countries whose energy requirements are increasing rapidly as a result of large-scale scale industrialization and growing population. Solar Flat plate collector is the main part of the solar system for tapping solar olar energy to some useful energy. ..."
