While De Forest's addition of a third element to the Audion ( the grid ) and the subsequent move to modulated ( voice ) radio is not disputed, De Forest did not put his device to work.

The sides of the rectangle can be divided into segments of length c, which divides the rectangle into a grid of squares of side length c. The greatest common divisor g is the largest value of c for which this is possible.

The " original " city was built to the north of Churchman Avenue, on a north / south " grid " pattern with alleys, centered on the widened roads of Main Street and Fifth Avenue.

While Grosse Pointe and Grosse Pointe Park are built on a standard street grid and are basically flat, Grosse Pointe Farms is partially built on the same grid flowing out of Detroit, but also features districts with irregular, curving street paths.

The neighborhoods in Grosse Pointe Park are built on a standard grid street pattern which flows out of Detroit, and housing ranges from tightly-packed single-and multi-family brick houses, often rentals, on the far west side of the Park, to rows of traditionally-styled single family homes generally averaging over, to multi-million dollar mansions, some of which are found on the lakeshore.

The grid plan dates from antiquity and originated in multiple cultures ; some of the earliest planned cities were built using grid plans.

By 2600 BC, Mohenjo-daro and Harappa, major cities of the Indus Valley Civilization ( present day Pakistan ), were built with blocks divided by a grid of straight streets, running north-south and east-west.

The baroque capital city of Malta, Valletta, dating back to the 16th Century, was built following a rigid grid plan of uniformly designed houses, dotted with palaces, churches and squares.

While some of this disparity is the result of distance from emergency medical facilities ( hospitals are usually built in a fairly late stage of the development of a suburban area ), it is clear that the lower speeds encouraged by the frequency of intersections decrease the severity of accidents occurring on streets within a grid plan.

In 2010, Presidio built the world's largest sodium-sulfur battery to provide power when the city's lone line to the United States power grid goes down.

* The fortified cities of Senglea and Valletta were both built on a grid plan by the Knights of Malta in the 16th century.

* The town of Paola, Malta, also known as Rahal Gdid ( New Town ), is built on a grid plan by the Grand Master Antoine de Paule.

Melbourne was planned as a free settlement in 1837 through the Hoddle Grid, drawn up by Robert Hoddle under instructions from George Gipps, the original plan for Melbourne as part of the first land sales ( prior to the planning only a handful of existing settlements were built on the fringe of the grid ).

Elizabeth Street, Melbourne in the centre of the grid was built over a gully and has therefore been prone to flooding.

Most older black boxes were built more like television studios, with a low pipe grid overhead.

Kyoto was built on a grid system, starting in 794.

The city of Kyoto was developed as a planned city in 794 as a new imperial capital ( then called Heian-kyō ), built on a grid layout modeled after the Tang dynasty capital of Chang ' an ( modern day Xi ' an ), and remained the capital for over a millennium.

The urban grid was based on the usual central north-south road ( cardo ) and central east-west route ( decumanus ).

( In Go, for example, the pieces are placed on intersections of lines on the grid, not in the areas bounded by borders, as in chess.

In this coordinate system the grid expands along with the Universe, and objects that are moving only due to the expansion of the Universe remain at fixed points on the grid.

Dots and boxes need not be played on a rectangular grid.

It can be played on a triangular grid or a hexagonal grid.

The earliest known chord keyboard was part of the " five-needle " telegraph operator station, designed by Wheatstone and Cooke in 1836, in which any two of the five needles could point left or right to indicate letters on a grid.

Thus a small voltage on the grid can be made to control a much larger voltage on the anode.

* Cascading failure, a failure in a system of interconnected parts, for example a power transmission grid, where the service provided depends on the operation of a preceding part, and the failure of a preceding part can trigger the failure of successive parts.

The image of a rectangular grid on a square under a diffeomorphism from the square onto itself.

Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it.

Power engineers may also work on systems that do not connect to the grid, called off-grid power systems, which in some cases are preferable to on-grid systems.

Control must expand outward like an ink spot on paper, systematically neutralizing and eliminating the insurgents in one sector of the grid, before proceeding to the next.

As Greenwich Village was once a rural hamlet, to the north of the 17th century European settlement on Manhattan Island, its street layout is more haphazard than the grid pattern of the 19th-century grid plan ( based on the Commissioners ' Plan of 1811 ).
