	Flache and Hegselmann: Do Irregular Grids make a Difference?
		Regular grids, or more particularly: rectangular grids, are the standard grid structure that is used in previous CA studies.
		Broadly, a regular grid assumes that the structure of the cell grid and the number of neighbours are homogenous for every location in the cellular space.
		A first reason to expect grid effects is that regular grids may impose restrictions on the transitivity of neighbourhood relationships.

	Welcome to Novartis India Limited - Pharmaceuticals
		Remember, it is important to know that the Amsler Grid in no way replaces a regular eye exam and examination of the retina.
		Since many patients with drusen, or the early stage of macular degeneration have no symptoms that would be detected by using the Amsler Grid, regular medical eye checks by an eye care professional are strongly recommended for everyone after age 40.
		If any area on the grid suddenly appears blurred, distorted, discolored, or in any way appears abnormal to a person taking this test, they are urged to contact their eye care professional immediately.

	BGA Ball Grid Array Package
		BGA pin connections are solder balls in a grid pattern, in the package bottom.
		Interstitial BGA: (IBGA) This package type carries additional pins, in a n offset pattern, in between the balls of a regular BGA pattern.
		It almost doubles the available connections on the same package size as a regular BGA.

	Grid network - Wikipedia, the free encyclopedia
		In a regular grid topology, each node in the network is connected with two neighbors along one or more dimensions.
		A grid network is a kind of computer network consisting of a number of (computer) systems connected in a grid topology.
		In general, when an n-dimensional grid network is connected circularly in more than one dimension, the resulting network topology is a torus, and the network is called "toroidal".

	manhattan_1993
		A regular grid of streets and Avenues which shapes the island and cuts out rectangular spaces which are occupied by cubic objects entering the dimension of depth (res extensa): Skyscrapers break the dimension of readiness, the difference between them and their lower surrounding forces meaning, e.g.
		a sign of a powerful trade as the tower of �Babel was to be a shrine that symbolized the power of [the tower�s architect].� (Auster, 44) Being surrounded by traffic of the grid of streets and avenues, towers present the power of stability in a steadily moving environment.
		Asymmetric streets are outstanding areas, they get meaning by being different from the symmetry of latticed streets.

	flowvis.txt
		Because the data points are given for integer coordinates in computational space, this constitutes a regular Cartesian grid.
		In areas where the grid is sparse, the flow appears as little ripples moving fast, because the convolution kernel has been compressed, and in areas where the grid is dense, the flow appears as large ripples moving slowly.
		Where the grid is sparse in physical space, we want to use a narrow convolution filter in computational space, as it will be stretched out when mapped.

	Grid Filters for Local Nonlinear Image Restoration
		A new approach to local nonlinear image restoration is described, based on approximating functions using a regular grid of points in a many-dimensional space.
		Grid filters require only a single presentation of the training samples, are numerically stable, leave unusual image features unchanged, and are a superset of order statistic filters.
		Unlike polynomials and neural networks whose filtering complexity per pixel is linear in the number of filter coefficients, grid filters have O(1) complexity per pixel.

	Project PAR-CVD: Parallel algorithms for the simulation and optimization of chemical vapour deposition processes
		Usually mathematical models are discreeted - in order to reduce the degrees of freedom - along a regular grid.
		In the sparse grid model however, grid nodes without effect on the solution need not be computed and are dropped, greatly reducing the complexity of the model.
		Sparse Grids are a numerically very efficient way to solve partial differential equations (PDE).

	Grid Screen for Digital Camera
		As the name implies, a grid screen is pretty much a regular screen with grid lines etched into the glass, much like the lines on graph paper.
		Most people don't - they're quite happy with the "standard" screen supplied with the camera, however some need specialised screens for specialised photographic tasks such as astro-photography, certain types of scientific photography and so on, and one type of screen is the Grid Screen.
		You can very easily put a Grid Screen on your camera's LCD screen, and for next-to-no-money.

	4Mation Demo - Grid Pro, the Grid and Pattern Designer
		An application to automatically generate grids, regular patterns and tessellations as Draw or Vector files.
		Grid sheets for games and other activities, such as the dot array for playing the "enclose-the-squares" game (I don't know what the game is actually called, but everyone must have played it at least once in their life!) or the hexagon grid for playing RPGs, can be produced and printed at any size or resolution.
		Grid lines and printer limits can be displayed on the sheet.

	Amsler Recording Chart
		The Amsler Grid is an easy and important way for you to test your vision on a regular basis, at home.
		If, while looking at the middle or the center of the grid, you notice that any of the lines are missing, bent, bowed, or distorted in any way, you should call the office for any appointment to come in as soon as possible.
		If you have some distortion on the grid already, please just be sure that this remains constant and that new areas on the grid are not becoming involved.

	Final Fantasy Odyssey FF X >> Sphere Grid
		Some spheres that you may find have better stats than the default grid, such as the HP Sphere, which lets you turn an empty node into a HP +300 node, which is better than a regular HP +200 node.
		The advantage of the sphere grid is that you can have more control over how you develop your characters overall.
		Miscellaneous spheres such as teleport spheres, let you teleport to anywhere on the grid.

	GI data models
		Although the regular grid is most used to represent static phenomena, it can easily be adapted to deal with dynamic change.
		The two extremes are (a) to perceive the space as being occupied by entities which are described by their attributes or properties, and whose position can be mapped using a geometric coordinate system, or (b) to imagine that the variation of an attribute of interest varies over the space as some continuous function or field.
		The 2D geometric surface is divided into square cells (known as pixles) whose size is determined by the resolution that is required to represent the variation of an attribute for a given purpose.

	REGULAR GRID FUNCTION
		We named the class RGF for regular grid function.
		To initiate work at SEP within the HCL framework, we implemented the traditional SEP Data Cube as a vector class.
		Each instance of an RGF has an associated RGFSpace, which is a vector space in HCL.

	Labeling Downtown (ResearchIndex)
		Abstract: American cities, especially their central regions usually have a very regular street pattern: We are given a rectangular grid of streets, each street has to be labeled with a name running along its street, such that no two labels overlap.
		For this restricted but yet realistic case an efficient algorithmic solution for the generally hard labeling problem gets in reach.

	OSGB FAQ
		Whilst longitude and latitude are shown on OS maps, they are only shown on the margins of the map and are very clumsy to use compared with the OS reference with its regular 1Km or 10Km grid lines which I would encourage the visitor to use.
		Grid North is as defined by the grid lines on the map which cannot match true north because the map is a flat representation of a curved surface.
		The north-south grid lines point west of true north for areas west of the true origin at 2 degrees west, and east for those to the east but this difference is only about 0.75 degrees per degree of longitude.

		The representation of these surfaces is in parametric form, which can be easily translated to the Euclidian space by using the structured grid property of the anatomical datasets.
		Various implicit surface representations have been proposed in the area of solid modeling [10,11,12] which can be used for higher order surfaces but cannot be directly implemented in a haptic application requiring a fast update rate.
		Therefore, the B-spline is represented in 3D as a tensor product of 1D splines eliminating the parametric representation [14].

	Polygonising a scalar field
		In this case the function is known everywhere but is sampled at the vertices of a regular 3D grid.
		The fundamental problem is to form a facet approximation to an isosurface through a scalar field sampled on a rectangular 3D grid.
		One very desirable control when polygonising a field where the values are known or can be interpolated anywhere in space is the resolution of the sampling grid.

	IDL: Plotting Irregularly-Gridded Data
		After a triangulation has been found for a set of irregularly-gridded data points, the TRIGRID function can be used to interpolate surface values to a regular grid.
		Now that we have the triangulation tr, the TRIGRID function can be used to return a regular grid of interpolated z values.
		Create a set of 32 irregularly-gridded data points in 3-D space that we can use as arguments to the TRIGRID and TRIANGULATE functions.
