Calcul de la puissance de résolution

Description

Cette séance de cours explique comment calculer la puissance de résolution d'un réseau de fentes avec interférence, en appliquant la définition et la formule de la puissance de résolution, qui est la plus petite différence entre deux longueurs d'onde normalisées par la longueur d'onde. L'instructeur montre comment trouver la puissance de résolution pour un réseau de n fentes avec interférence au m ème maximum, et comment déduire le deuxième ordre et le nombre de fentes en fonction de valeurs données. En combinant les équations, la séance de cours montre comment calculer la longueur d'onde delta et déterminer la valeur la plus proche de la longueur d'onde nominale.

Socialist calculation debate

The socialist calculation debate, sometimes known as the economic calculation debate, was a discourse on the subject of how a socialist economy would perform economic calculation given the absence of the law of value, money, financial prices for capital goods and private ownership of the means of production. More specifically, the debate was centered on the application of economic planning for the allocation of the means of production as a substitute for capital markets and whether or not such an arrangement would be superior to capitalism in terms of efficiency and productivity.

Calculation in kind

NOTOC Calculation in kind or calculation in-natura is a way of valuating resources and a system of accounting that uses disaggregated physical magnitudes as opposed to a common unit of calculation. As the basis for a socialist economy, it was proposed to replace money and financial calculation. In an in-kind economy products are produced for their use values (their utility) and accounted in physical terms. By contrast, in money-based economies, commodities are produced for their exchange value and accounted in monetary terms.

Economic calculation problem

The economic calculation problem (sometimes abbreviated ECP) is a criticism of using economic planning as a substitute for market-based allocation of the factors of production. It was first proposed by Ludwig von Mises in his 1920 article "Economic Calculation in the Socialist Commonwealth" and later expanded upon by Friedrich Hayek. In his first article, Mises described the nature of the price system under capitalism and described how individual subjective values (while criticizing other theories of value) are translated into the objective information necessary for rational allocation of resources in society.
