A language for specifying state transition systems, and is commonly used to create formal models of the effects of actions on the world. [6] Action languages are commonly used in the artificial intelligence and robotics domains, where they describe how actions affect the states of systems over time, and may be used for automated planning.
Sympathetic lightning is the tendency of lightning to be loosely coordinated across long distances. Discharges can appear in clusters when viewed from space. [22] [23] [24] [clarification needed] Upward lightning or ground-to-cloud lightning is a lightning flash which originates from the top of a grounded object and propagates upward from this ...
To facilitate the harvesting of lightning, a laser-induced plasma channel (LIPC) could theoretically be used to influence lightning to strike in a predictable location. A high power laser could be used to form an ionized column of gas, which would act as an atmospheric conduit for electrical discharges of lightning, which would direct the lightning to a ground station for harvesting.
Roy Cleveland Sullivan (February 7, 1912 – September 28, 1983) was an American park ranger in Shenandoah National Park in Virginia. Between 1942 And 1977, Sullivan was claimed to have been struck by lightning on seven occasions, surviving all of them.
StarDict, developed by Hu Zheng (胡正), is a free GUI released under the GPL-3.0-or-later license for accessing StarDict dictionary files (a dictionary shell). It is the successor of StarDic, developed by Ma Su'an (馬蘇安), continuing its version numbers.
Systematic Alien Verification for Entitlements (SAVE) is a program managed by United States Citizenship and Immigration Services (USCIS), a branch of the U.S. Department of Homeland Security (DHS). SAVE facilitates lookups on the immigration and nationality status of individuals in the United States . [ 1 ]
It is estimated that lightning injuries occur 240,000 times a year with 24,000 deaths. [1] Among pregnant women who are hit by lightning, the death of the fetus occurs in about half. [1] In the United States about 1 in 10,000 people are hit by lightning during their lifetime. [1] Males are affected four times more often than females. [1]
A state which can be represented as a wave function / ket in Hilbert space / solution of Schrödinger equation is called pure state. See "mixed state". Quantum numbers a way of representing a state by several numbers, which corresponds to a complete set of commuting observables.
