Cyber–physical System
Cyber-physical systems (CPS) are mechanisms controlled and monitored by computer algorithms, tightly integrated with the internet and its users. In cyber-physical systems, physical and software components are deeply intertwined, able to operate on different spatial and temporal scales, exhibit multiple and distinct behavioral modalities, and interact with each other in ways that change with context.Hu, J.; Lennox, B.; Arvin, F.,Robust formation control for networked robotic systems using Negative Imaginary dynamics Automatica, 2022. CPS involves transdisciplinary approaches, merging theory of cybernetics, mechatronics, design and process science.Patil T., Rebaioli L., Fassi I.,Cyber-physical systems for end-of-life management of printed circuit boards and mechatronics products in home automation: A review Sustainable Materials and Technologies, 2022.Suh, S.C., Carbone, J.N., Eroglu, A.E.: ''Applied Cyber-Physical Systems.'' Springer, 2014. The process control is often referred to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale (ratio)
The scale ratio of a model represents the proportional ratio of a linear dimension of the model to the same feature of the original. Examples include a 3-dimensional scale model of a building or the scale drawings of the elevations or plans of a building. In such cases the scale is dimensionless and exact throughout the model or drawing. The scale can be expressed in four ways: in words (a lexical scale), as a ratio, as a fraction and as a graphical (bar) scale. Thus on an architect's drawing one might read 'one centimeter to one meter', 1:100, 1/100, or . A bar scale would also normally appear on the drawing. Colon may also be substituted with a specific, slightly raised ratio symbol , ie. . General representation Generally, a representation may involve more than one scale at the same time. For example, a drawing showing a new road in elevation might use different horizontal and vertical scales. An elevation of a bridge might be annotated with arrows with a length proportion ...

Deep-sea Exploration
Deep-sea exploration is the investigation of physical, chemical, and biological conditions on the ocean waters and sea bed beyond the continental shelf, for scientific or Commerce, commercial purposes. Deep sea, Deep-sea exploration is an aspect of underwater exploration and is considered a relatively recent human activity compared to the other areas of geophysical research, as the deeper depths of the sea have been investigated only during comparatively recent years. The ocean depths still remain a largely unexplored part of the Earth, and form a relatively undiscovered domain. Scientific deep-sea exploration can be said to have begun when France, French scientist Pierre-Simon Laplace investigated the average depth of the Atlantic Ocean by observing tidal motions registered on Brazilian and African coasts circa the late 18th or early 19th century. However, the exact date of his investigation is unknown. He calculated the depth to be , a value later proven quite accurate by Echo ...
