**Degree (temperature)**— For other uses, see Degree (disambiguation). The term degree is used in several scales of temperature. The symbol ° is usually used, followed by the initial letter of the unit, for example “°C” for degree(s) Celsius. A degree can be defined as a… …92

**Degree of an algebraic variety**— The degree of an algebraic variety in mathematics is defined, for a projective variety V, by an elementary use of intersection theory. For V embedded in a projective space Pn and defined over some algebraically closed field K, the degree d of V… …93

**Degree diameter problem**— In graph theory, the degree diameter problem is the problem of finding the largest possible graph G (in terms of the size of its vertex set V) of diameter k such that the largest degree of any of the vertices in G is at most d. The size of G is… …94

**Degree Day**— A unit for measuring the extent that the outdoor daily average temperature (the mean of the maximum and minimum daily dry bulb temperatures) falls below (in the case of heating, see Heating Degree Day), or falls above (in the case of cooling,… …95

**Degree completion program**— A degree completion program is an educational program providing a way for learners to get college credit for learning that they acquired through life and work experience. Degree completion programs, unlike diploma mills, work within the… …96

**Degree matrix**— In the mathematical field of graph theory the degree matrix is a diagonal matrix which contains information about the degree of each vertex. It is used together with the adjacency matrix to construct the Laplacian matrix of a graph. Definition… …97

**Degree of coherence**— In optics, correlation functions are used to characterize the statistical and coherence properties of an electromagnetic field. The degree of coherence is the normalized correlation of electric fields. In its simplest form, termed g(1), it is… …98

**Degree of ionization**— A plasma lamp, illustrating a low degree of ionization (i.e. a partially ionized gas) The degree of ionization refers to the proportion of neutral particles, such as those in a gas or aqueous solution, that are ionized into charged particles. A… …99

**Degree of polymerization**— The degree of polymerization, or DP, is usually defined as the number of monomeric units in a macromolecule or polymer or oligomer molecule.[1][2][3] For a homopolymer, there is only one type of monomeric unit and the number average degree of… …100

**Degree of anonymity**— In anonymity networks (e.g. Tor, Crowds, Mixmaster, Tarzan, etc.) it is important to be able to measure quantitatively the guarantee that is given to the system. The degree of anonymity d is a device that was proposed at the 2002 Privacy… …
