Insulation system. The electrical insulation system for wires used in generators, electric motors, transformers, and other wire-wound electrical components is divided into different classes by temperature and temperature rise. The electrical insulation system is sometimes referred to as insulation class or thermal classification.
The science of accurately measuring and understanding the Earth's geometric shape, orientation in space, and gravitational field and how these properties change over time. Also geodetic network, reference network, or control point network. Also geodetic system, geodetic reference datum, or geodetic reference system.
For example, if a rule establishes a threshold at the value 6.5, it needs to be clear about whether a district with a value of exactly 6.5 will be classified into the lower or upper class (i.e., whether the definition of the lower class is <6.5 or ≤6.5 and whether the upper class is >6.5 or ≥6.5).
Climate change threatens people with increased flooding, extreme heat, increased food and water scarcity, more disease, and economic loss. Human migration and conflict can also be a result. [13] The World Health Organization (WHO) calls climate change the greatest threat to global health in the 21st century. [14]
Thermal mass. In building design, thermal mass is a property of the mass of a building that enables it to store heat and provide inertia against temperature fluctuations. It is sometimes known as the thermal flywheel effect. [1] The thermal mass of heavy structural elements can be designed to work alongside a construction's lighter thermal ...
Human geography or anthropogeography is the branch of geography which studies spatial relationships between human communities, cultures, economies, and their interactions with the environment, examples of which include urban sprawl and urban redevelopment. [1] It analyzes spatial interdependencies between social interactions and the environment ...
The Atlantic meridional overturning circulation ( AMOC) is the main ocean current system in the Atlantic Ocean. [1] : 2238 It is a component of Earth's ocean circulation system and plays an important role in the climate system. The AMOC includes Atlantic currents at the surface and at great depths that are driven by changes in weather ...
