  3. List of unsolved problems in economics - Wikipedia

    en.wikipedia.org/wiki/List_of_unsolved_problems...

    Transformation problem: The transformation problem is the problem specific to Marxist economics, and not to economics in general, of finding a general rule by which to transform the values of commodities based on socially necessary labour time into the competitive prices of the marketplace. The essential difficulty is how to reconcile profit in ...

  4. Theory of imputation - Wikipedia

    en.wikipedia.org/wiki/Theory_of_imputation

    In economics, the theory of imputation, first expounded by Carl Menger, maintains that factor prices are determined by output prices [6] (i.e. the value of factors of production is the individual contribution of each in the final product, but its value is the value of the last contributed to the final product (the marginal utility before reaching the point Pareto optimal).

  5. Eddy-current testing - Wikipedia

    en.wikipedia.org/wiki/Eddy-current_testing

    If the material contains a crack or flaw which make the spatial distribution of the electrical conductivity nonuniform, the path of the eddy currents is perturbed and the impedance of the coil which generates the AC magnetic field is modified. By measuring the impedance of this coil, a crack can hence be detected.

  6. Econophysics - Wikipedia

    Econophysics is a non-orthodox (in economics) interdisciplinary research field, applying theories and methods originally developed by physicists in order to solve problems in economics, usually those including uncertainty or stochastic processes and nonlinear dynamics.

    The dead zone is approximately 5 mm and there is no flaw detection in this zone. Calibration blocks with side drilled holes as shown in Reference [4] and ISO 10863 used to validate the "dead zone" and sizing accuracy.

  8. Fault detection and isolation - Wikipedia

    en.wikipedia.org/wiki/Fault_detection_and_isolation

    Fault detection, isolation, and recovery (FDIR) is a subfield of control engineering which concerns itself with monitoring a system, identifying when a fault has occurred, and pinpointing the type of fault and its location. Two approaches can be distinguished: A direct pattern recognition of sensor readings that indicate a fault and an analysis ...
