Dimensional lumber - Wikipedia, the free encyclopedia Dimensional lumber made from softwood is typically used for construction, while hardwood boards are more commonly used for making cabinets or furniture. Sizes for dimensional lumber made from hardwoods varies from the sizes for softwoods. Dimensional lumber is a term used in North America for lumber that is cut to standardized width and depth specified in inches. en.wikipedia.org /wiki/Two_by_four

Database - Wikipedia, the free encyclopedia The dimensional model is often implemented on top of the relational model using a star schema, consisting of one table containing the facts and surrounding tables containing the dimensions. The dimensional model is a specialized adaptation of the relational model used to represent data in data warehouses in a way that data can be easily summarized using OLAP queries. Database as a single word became common in Europe in the early 1970s and by the end of the decade it was being used in major American newspapers. en.wikipedia.org /wiki/Database   (3224 words)

Dimensional analysis - Wikipedia, the free encyclopedia Dimensional symbols, such as L, form a group: there is an identity, 1; there is an inverse to L, which is 1/L, and L raised to any rational power p is a member of the group, having an inverse of 1/L raised to the power p. Dimensional analysis is a conceptual tool often applied in physics, chemistry, and engineering to understand physical situations involving a mix of different kinds of physical quantities. Ultimately, it can be seen that dimensional analysis and the requirement for physical equations to be dimensionally homogeneouos reflects the idea that the laws of physics are independent of the units employed to measure the physical variables. en.wikipedia.org /wiki/Dimensional_analysis   (2655 words)

OLAP article - OLAP database data mining Relational databases dimensional database - What-Means.com It uses a summary database, has a specific dimensional database engine and creates the required schema as a dimensional set of both base data and aggregations. A better model for querying, but worse for operational use, is a dimensional database. ROLAP works directly with relational databases, the base data and the dimension tables are stored as relational tables and new tables are created to hold the aggregation information. www.what-means.com /encyclopedia/OLAP   (765 words)

Dimensional database -- Facts, Info, and Encyclopedia article A dimensional database is one which, rather than storing data in multiple two dimensional tables (as a (A database in which relations between information items are explicitly specified as accessible attributes) relational databases does), represents key data entities as different (The magnitude of something in a particular direction (especially length or width or height)) dimensions. The relational database model uses a two-dimensional structure of rows and columns to store data, in tables of (A document that can serve as legal evidence of a transaction) records corresponding to real-world entities. In a multi-dimension database system, the data is presented to the user in such a way as to represent a (Click link for more info and facts about hypercube) hypercube, or multi-dimensional array, where each individual data value is contained within a cell accessible by multiple indexes. www.absoluteastronomy.com /encyclopedia/d/di/dimensional_database.htm   (915 words)

Advantage Lumber - sizing information Lumber is generally sized according to thickness, as in the case of rough sawn lumber, or in specific widths, thicknesses and/or lengths as in the case of dimensional lumber. Dimensional lumber: This measuring method is probably the most recognized by the average person. Lumber sized according to "Quarters" reflects the number of quarters of an inch thick the lumber is. To figure the thickness of a board referenced in "quarters" sizes, simply divide the second number (4) into the first number. www.advantagelumber.com /sizes.htm   (915 words)

Dimensional Analysis in Operations Research Dimensional Analysis, though it has had any occasional use in Operations Research and Management Science, is potentially useful in those applications such as inventory and queueing where problems involve combinations of time, quantities, and objective function, and where the factors and effects involved are understood but the form of the solutions is not known. Nevertheless a preliminary dimensional analysis would show that the true exponent for the first term is 0.5 (and not 0.498 or 0.506) and the correct form is the same as that given in equation (13). Dimensional Analysis (DA) is a technique that has been used by physicists and engineers for many years to obtain preliminary solutions to physical problems. www.mcs.vuw.ac.nz /~vignaux/docs/diminor.html   (3179 words)

Three-Dimensional Chess Unfortunately, the three sides are in a relationship such that one is, in effect, before, and the other is after, the third player, so the array is not symmetric with only two players. The fact that each of the three arrays is in a different orientation forces players to think three-dimensionally. Also, the top and bottom three levels are small rectangles; the green area simply shows where these rectangles stand in relation to the central 5 x 5 square of the five middle levels, so that alignment is unambiguous. www.hypermaths.org /quadibloc/chess/ch05.htm   (1746 words)

Northwest Forest Industry - Lumber Manufacturing Dimensional lumber is the product of the sawmill where it is mechanically shaped to industry standard dimensions - width, thickness and length. Dimensional wood is also used in combination with other wood-based materials to construct strong, light-weight engineered roof trusses and floor beams. On the other hand, hardwoods (birch, oak and maple), with their noticable grain and colour characteristics, are used in millwork (doors, windows and frames), all kinds of moldings, interior wall paneling, flooring, cabinetry and furniture. bolt.lakeheadu.ca /~borfor/lumber   (1746 words)

Four Dimensional Space The half radii of two one dimensional circles from different relations form the third triangle, whose hypotenuse is the radius of a four dimensional sphere. Four dimensional topology provides four, which are easily reduced to three, two and one (the sphere). The concept of four dimensional space has proven to be an enigma throughout the twentieth century. barbaria.com /god/math_physics/uft/03.htm   (7787 words)

Three dimensional simulations For the finite ridge simulations, (6.1) is replaced by the two-dimensional equivalent (4.2) between the north and south ends of the ridge. In addition, the circular and finite ridge shaped mountain flows are contrasted qualitatively with three-dimensional linear theory of Phillip’s (1984), Smith (1980, 1988, 1989), and numerical results of Reisner and Smolarkiewicz (1994). In the finite ridge tests, there is a slight increase in amplitude near the top of the model domain and is likely associated with a decrease in density with height. www.caps.ou.edu /~dweber/diss/chapter6.htm   (2806 words)

3-sphere - Wikipedia, the free encyclopedia There is a long-standing, unproven conjecture, known as the Poincaré conjecture, stating that the 3-sphere is the only three dimensional manifold with these properties (up to homeomorphism). It is a nonabelian, compact Lie group of dimension 3. What this means, loosely speaking, is that any loop, or circular path, on the 3-sphere can be continuously shrunk to a point without leaving the 3-sphere. www.wikipedia.org /wiki/3-sphere   (2015 words)

Steven Kent - Computer Games / 3D Artist The frame buffer usually stores 2 frames: one is being calculated by the 3D accelerator while the other one is being sent to the monitor. The term bitdepth is more commonly used to denote what a game or application needs to function properly, which is the number of colors plus other channels like alpha. For example, if you use 4 bits each for Red, Green, and Blue, then that leaves 4 bits for the alpha, so you have 16 colors for alpha. www.stevenkent.net /glossary.htm   (477 words)

adore23.memo A 3 dimensional entity with 0 length in each dimension is not the same thing as zero dimensional entity with no dimensions at all to have zero length in. So Source is scalar, zero dimensional, and its main purpose is to either rest in peace or virtually shatter into facets of itself to experience illusions of dimension in the fabric of consciousness. They have a zero dimensional entity confused with a 0x0x0 3 dimensional entity which is in fact a nothing. www.lightlink.com /archives/homer/adore23.memo   (477 words)

Dimensionality In three-dimensional space the origin (the point where the zeros or all three number lines coincide) is defined by the Cartesian co-ordinates (0,0,0). A point, a line, a square, and a cube are hypercubes of order zero, one, two and three respectively. It is characterised by the number line - Extending from negative infinity, through a fixed zero point to positive infinity with a linear scale such that a movement of one unit at a given point on the line is the same 'distance' as at any other point on the line. www.cix.co.uk /~treatid/Dimensionality.htm   (477 words)

The Game Of Three Dimensional Eight Level Chess A line, which is the intersection of two planes, can also be named this way. The three lines on the board in the diagram are the a8 column, the 3d file, and the 76 rank. In the Three Coordinate Algebraic System, the notation of a point is accomplished by naming the three common planes to the point. www.hixoxih.com /games/chess/3D8L.htm   (3544 words)

Three-Dimensional Cursor For a maximum voxel algorithm each point along the three lines is drawn or not drawn according to whether the point is considered to be in front of or behind an obscuring feature, using the same depth estimation algorithm used by the two-dimensional active cursor. This cursor defines the same three lines as in the three-dimensional overlay cursor, except that, instead of drawing the projected lines over the rendered volume, they are effectively merged into the data. This may be thought of as a large, three-dimensional crosshair. www.atnf.csiro.au /pasa/14_1/gooch/paper/node3.html   (569 words)
