- Queensboro Bridge

The Queensboro Bridge also runs across Roosevelt Island, and an elevator allowing both pedestrian and vehicular access to the island was added to the bridge in 1930, but elevator service was discontinued in 1955 following the opening of the Roosevelt Island Bridge, and the elevator was demolished in 1970.

Electrons are transferred serially through the gain stages making up the multiplication register of an EMCCD. The high voltages used in these serial transfers induce the creation of additional charge carriers through impact ionisation.
in an EMCCD there is a dispersion (variation) in the number of electrons output by the multiplication register for a given (fixed) number of input electrons (shown in the legend on the right). The probability distribution for the number of output electrons is plotted logarithmically on the vertical axis for a simulation of a multiplication register. Also shown are results from the empirical fit equation shown on this page.

- Sexual assault

These actions may include extortion, blackmail, torture, threats to induce favors, or even sexual assault.

Central bank independence versus inflation. This often cited research published by Alesina and Summers (1993) is used to show why it is important for a nation's central bank (i.e.-monetary authority) to have a high level of independence. This chart shows a clear trend towards a lower inflation rate as the independence of the central bank increases. The generally agreed upon reason independence leads to lower inflation is that politicians have a tendency to create too much money if given the opportunity to do it. The Federal Reserve System in the United States is generally regarded as one of the more independent central banks

The Federal Reserve System (also known as the Federal Reserve or simply the Fed) is the central banking system of the United States of America.

- Federal Reserve

Most central banks also have supervisory and regulatory powers to ensure the stability of member institutions, to prevent bank runs, and to discourage reckless or fraudulent behavior by member banks.

- Central bank

The belief is that without this aid, the crippled banks would not only become bankrupt, but would create rippling effects throughout the economy leading to systemic failure.

- Bank regulation

According to former U.S. Federal Reserve chairman Ben Bernanke, the Great Depression was caused by the Federal Reserve System, and much of the economic damage was caused directly by bank runs.

- Bank run

There is a consensus that the Federal Reserve System should have cut short the process of monetary deflation and banking collapse, by expanding the money supply and acting as lender of last resort.

Divide-and-conquer approach to sort the list (38, 27, 43, 3, 9, 82, 10) in increasing order. Upper half: splitting into sublists; mid: a one-element list is trivially sorted; lower half: composing sorted sublists.

Signal-flow graph connecting the inputs x (left) to the outputs y that depend on them (right) for a "butterfly" step of a radix-2 Cooley–Tukey FFT. This diagram resembles a butterfly (as in the morpho butterfly shown for comparison), hence the name, although in some countries it is also called the hourglass diagram.
Tree created using the Logo programming language and relying heavily on recursion. Each branch can be seen as a smaller version of a tree.
The basic step of the Cooley–Tukey FFT for general factorizations can be viewed as re-interpreting a 1d DFT as something like a 2d DFT. The 1d input array of length N = N1N2 is reinterpreted as a 2d N1&times;N2 matrix stored in column-major order. One performs smaller 1d DFTs along the N2 direction (the non-contiguous direction), then multiplies by phase factors (twiddle factors), and finally performs 1d DFTs along the N1 direction. The transposition step can be performed in the middle, as shown here, or at the beginning or end. This is done recursively for the smaller transforms.

The Cooley–Tukey algorithm, named after J. W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm.

- Cooley–Tukey FFT algorithm

In the context of fast Fourier transform algorithms, a butterfly is a portion of the computation that combines the results of smaller discrete Fourier transforms (DFTs) into a larger DFT, or vice versa (breaking a larger DFT up into subtransforms).

- Butterfly diagram

A divide-and-conquer algorithm recursively breaks down a problem into two or more sub-problems of the same or related type, until these become simple enough to be solved directly.

- Divide-and-conquer algorithm

This is often referred to as the divide-and-conquer method; when combined with a lookup table that stores the results of previously solved sub-problems (to avoid solving them repeatedly and incurring extra computation time), it can be referred to as dynamic programming or memoization [sic].

- Recursion (computer science)

This is a divide-and-conquer algorithm that recursively breaks down a DFT of any composite size multiplications by complex roots of unity traditionally called twiddle factors (after Gentleman and Sande, 1966 ).

Locally linear strongly regular graph with parameters.

- Berlekamp–Van Lint–Seidel graph

It has 30 vertices, 120 edges, 210 faces (120 triangles and 90 squares), 180 cells (60 tetrahedra and 120 triangular prisms) and 62 4-faces (12 5-cells, 30 tetrahedral prisms and 20 3-3 duoprisms).

- Stericated 5-simplexes

Like the Berlekamp–van Lint–Seidel graph and the unknown solution to Conway's 99-graph problem, every edge is part of a unique triangle and every non-adjacent pair of vertices is the diagonal of a unique square.

- 3-3 duoprism

This graph is the Berlekamp–Van Lint–Seidel graph.
