Distance education Distance education, or distance learning, is a field of education that focuses on the pedagogy/andragogy, technology, and instructional systems design that are effectively incorporated in delivering education to students who are not physically "on site" to receive their education. Instead, teachers and students may communicate asynchronously (at times of their own choosing) by exchanging printed or electronic media, or through technology that allows them to communicate in real time (synchronously).
Distance Education and Training Council The Distance Education and Training Council (DETC) is a non-profit accreditation agency recognized by Council for Higher Education Accreditation and the United States Department of Education.

Distance geometry Distance geometry is the characterization and study of sets of points based only on given values of the distances between member pairs. Therefore distance geometry has immediate relevance where distance values are determined or considered, such as in surveying, cartography and physics.
Distance line A distance line or penetration line is an item of diving equipment used by SCUBA divers as a means of returning to a safe starting point in conditions of low visibility, water currents or where pilotage is difficult. They are often used in cave diving and wreck diving where the diver must return to open water after a penetration when it may be difficult to discern the return route.
Distance matrix In mathematics, a distance matrix is a matrix (two-dimensional array) containing the distances, taken pairwise, of a set of points. It is therefore a symmetric NĂ—N matrix containing non-negative reals as elements, given N points in Euclidean space.
Distance measures (cosmology) Distance measures are used in physical cosmology to give a natural notion of the distance between two objects or events in the universe. They are often used to tie some observable quantity (such as the luminosity of a distant quasar, the redshift of a distant galaxy, or the angular size of the acoustic peaks in the CMB power spectrum) to another quantity that is not directly observable, but is more convenient for calculations (such as the comoving coordinates of the quasar, galaxy, etc).
Distance model In music a distance model is the alternation of two different intervals to create a non-diatonic musical mode such as the 1:3 distance model, the alternation of semitones and minor thirds: C-Eb-E-G-Ab-B-C. This scale is also an example of polymodal chromaticism as it includes both the tonic and dominant as well as "'two of the most typical degrees from both major and minor' (E and B, Eb and Ab, respectively) ([KĂˇrpĂˇti 1975] p.

Distance-regular graph In mathematics, a distance-regular graph is a regular graph (mathematics) such that, given any two vertices v and w at any distance i, the number of vertices adjacent to w and at distance j from v depends only on i and j, not on the particular pair of vertices. Every distance-transitive graph is distance regular.
Distance-transitive graph In mathematics, a distance-transitive graph is a graph (mathematics) such that, given any two vertices v and w at any distance i, and any other two vertices x and y at the same distance, there is an automorphism of the graph that carries v to x and w to y.

Distinguish In law, to distinguish a case means to differentiate the facts of the case before the court from the facts of a case of precedent where there is an apparent similarity. By successfully distinguishing a case, the holding or legal reasoning of the earlier case will either not apply or will be limited.
Distinguish between Power and Authority To distinguish between power and authority we must understand what each means. Although they are very similar as â€authority is based on the right to wield powerâ€™ from [Robert Dahl]â€™s theory, power in itself is â€exercised over those who are harmed by its use, whether they are aware they are being harmed or notâ€™.

Distributed element model The distributed element model or transmission line model of electronic circuits assumes that each circuit element is finite, as opposed to infinitesimal, and that the wires connecting elements are not perfect conductors -- that is, they have impedance. The model challenges the lumped element model by assuming non-uniform current along each branch and non-uniform voltage along each node.
