a thermal analysis technique in which a tiny sample pan is heated together with an empty reference pan and the difference in heat flow between the two measured as a function of temperature.

(mechanics) A type of differential that allows its output shafts to rotate at different speeds but can limit the maximum difference in angular velocity between the output shafts, allowing greater torque to be applied to the slower-spinning shaft(s) and generally resulting in better traction than older-design differentials.

(mathematics) The equation that defines the Legendre polynomials: d/dx[(1-x²)d/dxP_n(x)]+n(n+1)P_n(x)=0.

plural of limited-slip differential

plural of differential thermal analysis

(mathematical analysis, dated or historical) Ricci calculus; the rules of index notation and manipulation for tensors and tensor fields, as developed by Gregorio Ricci-Curbastro.

(differential geometry) A type of differential geometry in which the differential invariants studied are invariant under volume-preserving affine transformations.
