Dimenhydrinate

Dimenhydrinate, sold as Dramamine and Gravol, is an over-the-counter medication combining the antihistamine diphenhydramine with 8-chlorotheophylline, best known for preventing and treating motion sickness and nausea since 1949.

Dimension

Dimension in topology is a numerical invariant, usually the Lebesgue covering dimension, counting a space's independent directions; homeomorphic spaces share it, and Euclidean space Rn has dimension n.

Dimension (data warehouse)

A dimension, or data dimension, is a data warehouse table of descriptive attributes such as customer, product, or date, joined to a central fact table in a star schema.

Dimension (vector space)

In linear algebra, the dimension of a vector space, also called its Hamel dimension, is the number of vectors in any basis of the space.

Dimension 20

Dimension 20 is an American actual play series that premiered in 2018 on Dropout, where comedians play tabletop roleplaying games, created and mostly dungeon-mastered by Brennan Lee Mulligan.

Dimension table

Dimension table: in data warehousing, the table storing descriptive attributes (product, customer, date) that give context to numeric facts in a fact table; wide, few rows, surrogate-keyed, star schema component per Kimball.

Dimension theory (algebra)

Dimension theory in commutative algebra studies the Krull dimension of a ring, the supremum of lengths of chains of prime ideals, introduced by Wolfgang Krull in 1928 and matching the geometric dimension of varieties.

Dimension W

Dimension W (ディメンションＷ) is a completed 16-volume, 116-chapter sci-fi action manga by Yuji Iwahara, serialized 2011–2019 in Young Gangan and Monthly Big Gangan; set in 2072, it follows Coil collector Kyouma Mabuchi and the android Mira, with a 12-episode 2016 anime and English release by Yen Press.

Dimensional analysis

Dimensional analysis is a method in physics and engineering that uses physical dimensions like mass, length, and time to check equations, suggest relationships, and reduce variables in experiments.

Dimensional Fund Advisors

Dimensional Fund Advisors (DFA) is an American investment firm founded in 1981 by David Booth and Rex Sinquefield, building funds around Fama-French factor research rather than stock picking.

Dimensional matrix

A dimensional matrix is a table whose columns are a problem's physical variables and whose rows are fundamental dimensions, central to dimensional analysis and the Buckingham pi theorem.

Dimensional modeling

Dimensional modeling is a data warehouse design method organizing numeric measurements into fact tables surrounded by denormalized dimension tables, presented by Ralph Kimball and Kevin Strehlo in 1995.

Dimensional regularization

Dimensional regularization is a quantum field theory technique that handles ultraviolet divergences by evaluating loop integrals in d dimensions, introduced in 1972 by 't Hooft and Veltman and others.

Dimensionality reduction

Dimensionality reduction, also called dimension reduction, transforms high-dimensional data into fewer coordinates while minimizing information loss, through linear methods such as PCA and nonlinear manifold methods such as t-SNE and UMAP.

Dimensioning, weighing and scanning

Dimensioning, weighing and scanning (DWS) is a warehouse data-capture method in which one system measures a parcel's dimensions, records its weight, and reads its barcode for billing.

Dimensionless physical constant

A dimensionless physical constant is a pure number in physics, such as the fine-structure constant, whose value does not depend on the choice of units.

Dimensionless quantity

A dimensionless quantity, also called a dimensionless or unitless quantity, is a physical quantity with no units, such as the Mach number, refractive index, and plane angle.
