The new global icosahedral–hexagonal grid point model GME of the Deutscher Wetterdienst
 Proc. ECMWF Seminar on Recent Developments in Numerical Methods for Atmospheric Modelling, ECMWF, Reading, United Kingdom
, 1998
"... The German Weather Service (Deutscher Wetterdienst) has recently developed a new operational global numerical weather prediction model, named GME, based on an almost uniform icosahedral–hexagonal grid. The GME gridpoint approach avoids the disadvantages of spectral techniques as well as the pole pro ..."

. These operators are derived for local basis functions that are orthogonal and conform perfectly to the spherical surface. The local basis functions, unique for each grid point, are the latitude and longitude of a spherical coordinate system whose equator and zero meridian intersect at the grid point
InstantGrid: A Framework for OnDemand Grid Point Construction
"... This paper proposes the InstantGrid framework for ondemand construction of grid points. The framework comprises the following components: (1) a centralized model of software management using an applicationcentric software grouping scheme; (2) proactive configuration of grid middleware, which shor ..."

A rational spectral collocation method with adaptively transformed Chebyshev grid points
 SIAM J. Sci. Comp
"... Abstract. A spectral collocation method based on rational interpolants and adaptive grid points is presented. The rational interpolants approximate analytic functions with exponential accuracy by using prescribed barycentric weights and transformed Chebyshev points. The locations of the grid points ..."

Analysis of Switching Dcdc Converters Using a Gridpoint Approach
"... Abstract A switching dcdc hverter in closedloop steadystate constitutes an operating point in the space of parameters describing its model. The inadequacy of conventional design of regulated converters, which is based on the assumption of smallsignal perturbations about a single operating point ..."

point, is addressed. A systematic and general modelling based on a gridpoint approach is thus proposed. Under this modelling approach, multiple operating points within the parameter space are reduced to some defined gridpoints describing the complete operation space of a regulated converter subjected
Geometric Retrieval for Grid Points in the RAM Model
 JOURNAL OF UNIVERSAL COMPUTER SCIENCE
"... We consider the problem of ddimensional searching (d 3) for four query types: range, partial range, exact match and partial match searching. Let N be the number of points, s be the number of keys specified in a partial match and partial range query and t be the number of points retrieved. We pre ..."

Turbulence statistics in fully developed channel flow at low Reynolds number
 J. Fluid Mech
, 1987
"... A direct numerical simulation of a turbulent channel flow is performed. The unsteady NavierStokes equations are solved numerically at a Reynolds number of 3300, based on thc mean centreline velocity and channel halfwidth, with about 4 x los grid points (192 x 129 x 160 in 2, y, 2). All essential t ..."

Practical animation of liquids
 Graphical Models and Image Processing
, 1996
"... We present a comprehensive methodology for realistically animating liquid phenomena. Our approach unifies existing computer graphics techniques for simulating fluids and extends them by incorporating more complex behavior. It is based on the NavierStokes equations which couple momentum and mass con ..."

Velocity and pressure are defined everywhere within this environment, and updated using a set of finite difference expressions
Convex Hull of Grid Points below a Line or a Convex Curve
"... Consider a finite nonvertical, and nondegenerate straightline segment s = [s0 ; s1 ] in the Euclidian plane E 2 . We give a method for constructing the boundary of the upper convex hull of all the points with integral coordinates below (or on) s, with abscissa in [x(s0); x(s1 )]. The algorithm ..."

This method may also be used for a line segment; in this case, k = O(log n), and the second method takes O(k 2 ) time, compared with O(k) for the first. 1 Upper Hull of Grid Points below a Line Segment This paper will consider integral hulls, i.e. convex hulls of set
