Metre
The metre (British spelling) or meter (American spelling; see spelling differences) (from the French unit , from the Greek noun , "measure"), symbol m, is the primary unit of length in the International System of Units (SI), though its prefixed forms are also used relatively frequently. The metre was originally defined in 1793 as one ten-millionth of the distance from the equator to the North Pole along a great circle, so the Earth's circumference is approximately km. In 1799, the metre was redefined in terms of a prototype metre bar (the actual bar used was changed in 1889). In 1960, the metre was redefined in terms of a certain number of wavelengths of a certain emission line of krypton-86. The current definition was adopted in 1983 and modified slightly in 2002 to clarify that the metre is a measure of proper length. From 1983 until 2019, the metre was formally defined as the length of the path travelled by light in a vacuum in of a second. After the 2019 redefi ...

Meade started manufacturing its own line of products in 1976, introducing 6" and 8" reflecting telescopes models in 1977. In 1980, the company ventured into the Schmidt-Cassegrain market that up to that time had been dominated by Celestron Corporation. Meade has a long history of litigation with other companies over infri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manfred Memorial Moon Mission
Manfred Memorial Moon Mission (4M) was the first private lunar probe to successfully fly by the Moon. It was led by LuxSpace, a child company of German OHB System, and named in honor of OHB Systems founder, professor Manfred Fuchs, who died in 2014. It was launched with the Chinese Chang'e 5-T1 test spacecraft on 23 October 2014. The lunar flyby took place on 28 October 2014, after which the spacecraft entered elliptical Earth orbit and continued transmission until 11 November 2014, exceeding its designed lifetime by four times. The spacecraft, along with the rocket stage to which it was attached, likely made impact with the surface of the Moon after its orbit decayed, on 4 March 2022. This made Luxembourg the eighth country to reach the surface of the Moon. Spacecraft The briefcase-sized probe, with a mass of 14 kg was built by the Luxemburg company LuxSpace. Its primary power source consisted of 28 non-rechargeable Saft LSH20 HTS lithium cells, which provided 4.5 W p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FINE MEP
FINE MEP (''Mechanical Electrical and Plumbing'') is a BIM CAD software tool for Building services engineering design, built on top of IntelliCAD. It provides full IFC (Industry Foundation Classes) support, according to the 2x3 IFC Standard. FINE BIM structure, enables a smart model shaping and high design accuracy, directly applied to the real 3D building model and its building services (HVAC, water supply, sewerage, electricity). Not only the building elements (i.e. walls, openings, roofs etc.), but also the components of the mechanical/electrical installations themselves (i.e. pipes, heating units, fittings, cables etc.) are all intelligent objects carrying their own attributes and interacting among each other. MEP design is supported by specific CAD commands (i.e. smart location of units/appliances, auto-routing commands for pipes/cables etc.) and further facilitated through sophisticated recognition and validation algorithms, providing a user-friendly modeling environment.

IDEA Architectural
In common usage and in philosophy, ideas are the results of thought. Also in philosophy, ideas can also be mental representational images of some object. Many philosophers have considered ideas to be a fundamental ontological category of being. The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings. In a popular sense, an idea arises in a reflexive, spontaneous manner, even without thinking or serious reflection, for example, when we talk about the ''idea'' of a person or a place. A new or an original idea can often lead to innovation. Etymology The word ''idea'' comes from Greek ἰδέα ''idea'' "form, pattern," from the root of ἰδεῖν ''idein'', "to see." History The argument over the underlying nature of ideas is opened by Plato, whose exposition of his theory of forms--which recurs and accumulates over the course of his many dialogs--appropriates and adds a new sense to the Greek word for th ...

Ishikawa Diagram
Ishikawa diagrams (also called fishbone diagrams, herringbone diagrams, cause-and-effect diagrams) are causal diagrams created by Kaoru Ishikawa that show the potential causes of a specific event. Common uses of the Ishikawa diagram are product design and quality defect prevention to identify potential factors causing an overall effect. Each cause or reason for imperfection is a source of variation. Causes are usually grouped into major categories to identify and classify these sources of variation. Overview The ''defect'' is shown as the fish's head, facing to the right, with the ''causes'' extending to the left as fishbones; the ribs branch off the backbone for major causes, with sub-branches for root-causes, to as many levels as required. Ishikawa diagrams were popularized in the 1960s by Kaoru Ishikawa, who pioneered quality management processes in the Kawasaki shipyards, and in the process became one of the founding fathers of modern management. The basic concept was fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Resource Management
In organizational studies, resource management is the efficient and effective development of an organization's resources when they are needed. Such resources may include the financial resources, inventory, human skills, production resources, or information technology (IT) and natural resources. In the realm of project management, processes, techniques and philosophies as to the best approach for allocating resources have been developed. These include discussions on functional vs. cross-functional resource allocation as well as processes espoused by organizations like the Project Management Institute (PMI) through their Project Management Body of Knowledge (PMBOK) methodology of project management. Resource management is a key element to activity resource estimating and project human resource management. Both are essential components of a comprehensive project management plan to execute and monitor a project successfully. As is the case with the larger discipline of project manage ...

Machine
A machine is a physical system using Power (physics), power to apply Force, forces and control Motion, movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by Animal power, animals and Human power, people, by natural forces such as Wind power, wind and Water power, water, and by Chemical energy, chemical, Thermal energy, thermal, or electricity, electrical power, and include a system of mechanism (engineering), mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems. Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input fo ...

Material
Material is a substance or mixture of substances that constitutes an object. Materials can be pure or impure, living or non-living matter. Materials can be classified on the basis of their physical and chemical properties, or on their geological origin or biological function. Materials science is the study of materials, their properties and their applications. Raw materials can be processed in different ways to influence their properties, by purification, shaping or the introduction of other materials. New materials can be produced from raw materials by synthesis. In industry, materials are inputs to manufacturing processes to produce products or more complex materials. Historical elements Materials chart the history of humanity. The system of the three prehistoric ages (Stone Age, Bronze Age, Iron Age) were succeeded by historical ages: steel age in the 19th century, polymer age in the middle of the following century (plastic age) and silicon age in the second half of t ...

Money
Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts, such as taxes, in a particular country or socio-economic context. The primary functions which distinguish money are as a medium of exchange, a unit of account, a store of value and sometimes, a standard of deferred payment. Money was historically an emergent market phenomenon that possess intrinsic value as a commodity; nearly all contemporary money systems are based on unbacked fiat money without use value. Its value is consequently derived by social convention, having been declared by a government or regulatory entity to be legal tender; that is, it must be accepted as a form of payment within the boundaries of the country, for "all debts, public and private", in the case of the United States dollar. Contexts which erode public confidence, such as the circulation of counterfeit money or domestic hyperinflation, can cause good money to lose its value. ...

LATAM Argentina
Aero 2000 S.A., d/b/a LATAM Airlines Argentina, formerly LAN Argentina, was an airline based in Buenos Aires, Argentina, and a member of the LATAM Airlines Group. History Prior to its acquisition by LAN Airlines, the airline was known by its legal name, Aero 2000. LAN Argentina became an affiliate member of the Oneworld airline alliance on April 1, 2007, but left on May 1, 2020. The airline was owned by LATAM Airlines Group (49%) and Argentine investors (51%). On August 28, 2013, an Argentine judge blocked the government's plan to break a long-term lease of hangar space to LAN in Aeroparque Jorge Newbery, which was seen as vital to the airline's operations. As its parent company, LAN merged with TAM Linhas Aéreas and rebranded to form LATAM Airlines, LAN Argentina also rebranded to ''LATAM Argentina''. LATAM Airlines agreed to pay more than $22 million in civil and criminal fines relating to a decade-old Argentine bribery case. The U.S. Securities and Exchange Commission ...
