Rain gauge. A rain gauge (also known as udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologists and hydrologists to gather and measure the amount of liquid precipitation over a predefined area, over a period of time. [1] It is used to determine the depth of precipitation (usually in mm) that occurs over a unit ...
Windows 7. Windows 7 is a major release of the Windows NT operating system developed by Microsoft. It was released to manufacturing on July 22, 2009, and became generally available on October 22, 2009. [10] It is the successor to Windows Vista, released nearly three years earlier.
The snow gauge consists of two parts: a copper catchment container; and the funnel-shaped gauge itself. The actual gauge is mounted on a pipe outdoors and is approximately 1.5 m (150 cm; 59 in; 4 ft 11 in) in height, while the container is 51.5 cm (20.3 in; 1 ft 8.3 in) in length. [citation needed]
Cheugugi (Hangul: 측우기, Hanja: 測雨器) is the first well-known rain gauge invented and used during the Joseon dynasty of Korea. It was invented and supplied to each provincial offices during the King Sejong the Great 's reign. As of 2010, only one example of the Cheugugi remains, known as the Geumyeong Cheugugi (Hangul: 금영측우기 ...
A "personal computer" version of Windows is considered to be a version that end-users or OEMs can install on personal computers, including desktop computers, laptops, and workstations. The first five versions of Windows– Windows 1.0, Windows 2.0, Windows 2.1, Windows 3.0, and Windows 3.1 –were all based on MS-DOS, and were aimed at both ...
Lorenz gauge condition. In electromagnetism, the Lorenz gauge condition or Lorenz gauge (after Ludvig Lorenz) is a partial gauge fixing of the electromagnetic vector potential by requiring The name is frequently confused with Hendrik Lorentz, who has given his name to many concepts in this field. [1] The condition is Lorentz invariant.
A particular choice of the scalar and vector potentials is a gauge (more precisely, gauge potential) and a scalar function ψ used to change the gauge is called a gauge function. [citation needed] The existence of arbitrary numbers of gauge functions ψ(r, t) corresponds to the U(1) gauge freedom of this theory. Gauge fixing can be done in many ...
Weather gage. The weather gage (sometimes spelled weather gauge) is the advantageous position of a fighting sailing vessel relative to another. It is also known as "nautical gauge" as it is related to the sea shore. The concept is from the Age of Sail and is now antique. A ship at sea is said to possess the weather gage if it is in any position ...
