Spatial weight matrix. The concept of a spatial weight is used in spatial analysis to describe neighbor relations between regions on a map. [1] If location is a neighbor of location then otherwise . Usually (though not always) we do not consider a site to be a neighbor of itself [2] so . These coefficients are encoded in the spatial weight matrix.
Red and blue capsule pills. The red pill and blue pill are metaphorical terms representing a choice between learning an unsettling or life-changing truth by taking the "red pill" or remaining in the contented experience of ordinary reality with the "blue pill". In Freudian psychology, the corresponding principles are the reality principle and ...
The Jacobian matrix for this coordinate change is (,,) = [] = [ ]. The determinant is ρ 2 sin φ . Since dV = dx dy dz is the volume for a rectangular differential volume element (because the volume of a rectangular prism is the product of its sides), we can interpret dV = ρ 2 sin φ dρ ...
Positive and zero values have been highlighted. In bioinformatics, the BLOSUM (BLO cks SU bstitution M atrix) matrix is a substitution matrix used for sequence alignment of proteins. BLOSUM matrices are used to score alignments between evolutionarily divergent protein sequences. They are based on local alignments.
The Matrix: Path of Neo is a 2005 action-adventure video game developed by Shiny Entertainment and published by Atari. The game was written and co-directed by the Wachowskis, who wrote and directed the first three The Matrix films and the 2003 video game Enter the Matrix, also developed by Shiny Entertainment. Players control the character Neo ...
Hyaline cartilage exists on the sternal ends of the ribs, in the larynx, trachea, and bronchi, and on the articulating surfaces of bones. It gives the structures a definite but pliable form. The presence of collagen fibres makes such structures and joints strong, but with limited mobility and flexibility. Hyaline cartilage is the most prevalent ...
Strassen algorithm. In linear algebra, the Strassen algorithm, named after Volker Strassen, is an algorithm for matrix multiplication. It is faster than the standard matrix multiplication algorithm for large matrices, with a better asymptotic complexity, although the naive algorithm is often better for smaller matrices.
Conglomerate (/ kənˈɡlɒmərɪt /) is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel -size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically ...
