  2. Open system (systems theory) - Wikipedia

    en.wikipedia.org/wiki/Open_system_(systems_theory)

    Open systems have input and output flows, representing exchanges of matter, energy or information with its surroundings. An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the ...

    en.wikipedia.org/wiki/Systems_chemistry

    Systems chemistry is the science of studying networks of interacting molecules, to create new functions from a set (or library) of molecules with different hierarchical levels and emergent properties. [1] [2] Systems chemistry is also related to the origin of life (abiogenesis). [3]

    Open system: A state and characteristics of that state in which a system continuously interacts with its environment. Open systems are those that maintain their state and exhibit the characteristics of openness previously mentioned.

  5. Living systems - Wikipedia

    en.wikipedia.org/wiki/Living_systems

    A presentation on information flow in living systems. Living systems are life forms (or, more colloquially known as living things) treated as a system. They are said to be open self-organizing and said to interact with their environment. These systems are maintained by flows of information, energy and matter. Multiple theories of living systems ...

    The open systems are systems that allow interactions between its internal elements and the environment. An open system is defined as a "system in exchange of matter with its environment, presenting import and export, building-up and breaking-down of its material components." [4] For example, living organism. Closed systems, on the other hand ...

    To systems scientists, the world can be understood as a system of systems. The field aims to develop interdisciplinary foundations that are applicable in a variety of areas, such as psychology, biology, medicine, communication, business management, engineering, and social sciences. Systems science covers formal sciences such as complex systems ...

  8. Thermodynamic system - Wikipedia

    en.wikipedia.org/wiki/Thermodynamic_system

    Properties of isolated, closed, and open thermodynamic systems in exchanging energy and matter. A thermodynamic system is a body of matter and/or radiation separate from its surroundings that can be studied using the laws of thermodynamics. Thermodynamic systems can be passive and active according to internal processes.
