Most micromachines act as transducers; in other words, they are either sensors or actuators.. Sensors convert information from the environment into interpretable electrical signals.
Bulk micromachining [1] is a process used to produce micromachinery or microelectromechanical systems (MEMS).. Unlike surface micromachining, which uses a succession of thin film deposition and selective etching, bulk micromachining defines structures by selectively etching inside a substrate.
It has also been used to construct micromachinery. As an offshoot of researchers attempting to further miniaturize microtechnology, nanotechnology emerged in the 1980s, particularly after the invention of new microscopy techniques. [4] These produced materials and structures that have 1-100 nm in dimensions. [4]
Microtechnology is a set of processes, techniques and tools used to create structures having at least one dimension of a functional feature in order of micrometer (one millionth of a metre, or 10-6 metre, or 1μm), typically within the range of 10 −4 to 10 −7 meters and application of those structures in more complex systems.
The Vietnamese Wikipedia initially went online in November 2002, with a front page and an article about the Internet Society.The project received little attention and did not begin to receive significant contributions until it was "restarted" in October 2003 [3] and the newer, Unicode-capable MediaWiki software was installed soon after.
DatVietVAC (or Dat Viet VAC) is a Vietnamese media, entertainment and technology group. [1] [2] Founded in 1994 by Dinh Ba Thanh, [3] it is described as Vietnam's first and largest media company and launched the first private TV channel in the country. [4] The group operates the major Vietnamese OTT streaming platform VieON. [5] [6]
The Ministry of Industry and Trade (MOIT, Vietnamese: Bộ Công thương) is the government ministry in Vietnam responsible for the advancement, promotion, governance, regulation, management and growth of industry and trade.
The Vietnam People's Navy has itself built six Tarantul-class corvettes (Molniya class) with Russian supervision and has designed and built the first warships of the TT-400TP gunboat class. [94] Vietnam also purchased two Pohang-class corvettes were purchased from South Korea, one in 2017 and
