Time delay and integration. A time delay and integration or time delay integration (TDI) charge-coupled device (CCD) is an image sensor for capturing images of moving objects at low light levels. While using similar underlying CCD technology, in operation it contrasts with staring arrays and line scanned arrays. It works by synchronized ...
Time–space compression. Time–space compression (also known as space–time compression and time–space distanciation) is an idea referring to the altering of the qualities of space–time and the relationship between space and time that is a consequence of the expansion of capital. It is rooted in Karl Marx 's notion of the "annihilation ...
A logical characterization of PSPACE from descriptive complexity theory is that it is the set of problems expressible in second-order logic with the addition of a transitive closure operator. A full transitive closure is not needed; a commutative transitive closure and even weaker forms suffice. It is the addition of this operator that ...
Laplace transform. In mathematics, the Laplace transform, named after Pierre-Simon Laplace ( / ləˈplɑːs / ), is an integral transform that converts a function of a real variable (usually , in the time domain) to a function of a complex variable (in the complex-valued frequency domain, also known as s-domain, or s-plane ).
A point in three-dimensional Euclidean space can be located by three coordinates. Euclidean space is the fundamental space of geometry, intended to represent physical space. Originally, in Euclid's Elements, it was the three-dimensional space of Euclidean geometry, but in modern mathematics there are Euclidean spaces of any positive integer ...
The program is managed by the Space Development Agency (SDA) as part of the new National Defense Space Architecture (NDSA). [22] [23] CIA Director Mike Pompeo called for additional funding to achieve a full-fledged "Strategic Defense Initiative for our time, the SDI II" though it is unclear if this had anything to do with SDA.
Definition. Let , …, be n + 1 points in a Euclidean space, a flat or an affine space of dimension n that are affinely independent; this means that there is no affine subspace of dimension n − 1 that contains all the points, or, equivalently that the points define a simplex.
Complete metric space. In mathematical analysis, a metric space M is called complete (or a Cauchy space) if every Cauchy sequence of points in M has a limit that is also in M . Intuitively, a space is complete if there are no "points missing" from it (inside or at the boundary). For instance, the set of rational numbers is not complete, because ...
