EHang
Guangzhou EHang Intelligent Technology Co. Ltd is a company based in Guangzhou, China that develops and manufactures autonomous aerial vehicles (AAVs) and passenger AAVs which have entered service in China for aerial cinematography, photography, emergency response, and survey missions. History EHang announced the ''Ehang 184'', introduced at the Consumer Electronics Show in January 2016, as the world's first AAV capable of carrying passengers. The company announced plans with Dubai's Road & Transportation Agency in 2017 to launch an autonomous flying-taxi service starting in the summer of 2017, but didn't succeed. The company has also worked on a project with Nevada's Institute for Autonomous Systems for an AAV taxi that can transport a single passenger for up to 23 minutes with the EHang 184. In November 2018, an agreement was signed with the city of Lyon, France, to open a research center there. At the same time, a cooperation agreement was concluded with the Austrian aer ...

Subsequent productions Two years later it opened Off-Broadway at the Circle in the Square Downtown on Bleecker Street on October 16, 1966. The production was directed by Alan Arkin, using the pseudonym "Roger Short". Arkin had stepped in as director about two weeks before it opened and after two directors had quit. He used a pseudonym because he was under contract to begin direction of ''Hail, Scrawdyke!'' only a week later. The US production starred Dustin Hoffman as Valentine Brose, Alexandra Berlin as Betty Dorrick, Dana Elcar as Price, Carl Gabler as Aly, Joseph Maher as Reverend Mort and Elizabeth Wilson as Mrs. Murray. The play was the first major critical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hartree
The hartree (symbol: ''E''h or Ha), also known as the Hartree energy, is the unit of energy in the Hartree atomic units system, named after the British physicist Douglas Hartree. Its CODATA recommended value is = The hartree energy is approximately the electric potential energy of the hydrogen atom in its ground state and, by the virial theorem, approximately twice its ionization energy; the relationships are not exact because of the finite mass of the nucleus of the hydrogen atom and relativistic corrections. The hartree is usually used as a unit of energy in atomic physics and computational chemistry: for experimental measurements at the atomic scale, the electronvolt (eV) or the reciprocal centimetre (cm−1) are much more widely used.
