  2. Structural analog - Wikipedia

    en.wikipedia.org/wiki/Structural_analog

    A structural analog, also known as a chemical analog or simply an analog, is a compound having a structure similar to that of another compound, but differing from it in respect to a certain component. [1] [2] [3] It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or ...

  3. Analog device - Wikipedia

    en.wikipedia.org/wiki/Analog_device

    An analog computer is a form of computer that uses electrical, mechanical, or hydraulic phenomena to model the problem being solved. More generally an analog computer uses one kind of physical quantity to represent the behavior of another physical system, or mathematical function. Modeling a real physical system in a computer is called simulation.

  4. Analog computer - Wikipedia

    en.wikipedia.org/wiki/Analog_computer

    An analog computer or analogue computer is a type of computation machine (computer) that uses physical phenomena such as electrical, mechanical, or hydraulic quantities behaving according to the mathematical principles in question (analog signals) to model the problem being solved.

  5. Unconventional computing - Wikipedia

    en.wikipedia.org/wiki/Unconventional_computing

    An analog computer is a type of computer that uses analog signals, which are continuous physical quantities, to model and solve problems. These signals can be electrical, mechanical, or hydraulic in nature. Analog computers were widely used in scientific and industrial applications, and were often faster than digital computers at the time.

  6. Chemical computer - Wikipedia

    en.wikipedia.org/wiki/Chemical_computer

    A chemical computer, also called a reaction-diffusion computer, Belousov–Zhabotinsky (BZ) computer, or gooware computer, is an unconventional computer based on a semi-solid chemical "soup" where data are represented by varying concentrations of chemicals. [1] The computations are performed by naturally occurring chemical reactions.

  7. Neuromorphic computing - Wikipedia

    en.wikipedia.org/wiki/Neuromorphic_computing

    Neuromorphic engineering translates what we know about the brain's function into computer systems. Work has mostly focused on replicating the analog nature of biological computation and the role of neurons in cognition. The biological processes of neurons and their synapses are dauntingly complex, and thus very difficult to artificially simulate.

  8. Fluidics - Wikipedia

    en.wikipedia.org/wiki/Fluidics

    Fluidics, or fluidic logic, is the use of a fluid to perform analog or digital operations similar to those performed with electronics. The physical basis of fluidics is pneumatics and hydraulics, based on the theoretical foundation of fluid dynamics.

  9. Computational chemistry - Wikipedia

    en.wikipedia.org/wiki/Computational_chemistry

    Computational chemistry is a branch of chemistry that uses computer simulations to assist in solving chemical problems. [1] It uses methods of theoretical chemistry incorporated into computer programs to calculate the structures and properties of molecules , groups of molecules, and solids. [ 2 ]
