Smart antennaSmart antennas (also known as adaptive array antennas, digital antenna arrays, multiple antennas and, recently, MIMO) are antenna arrays with smart signal processing algorithms used to identify spatial signal signatures such as the direction of arrival (DOA) of the signal, and use them to calculate beamforming vectors which are used to track and locate the antenna beam on the mobile/target. Smart antennas should not be confused with reconfigurable antennas, which have similar capabilities but are single element antennas and not antenna arrays.
Monopôle magnétiqueUn monopôle magnétique est une particule hypothétique qui porterait une masse (ou charge) magnétique ponctuelle, au contraire des aimants habituels qui possèdent deux pôles magnétiques opposés. L'existence de monopôles magnétiques est exclue par l'électromagnétisme classique et par la théorie de la relativité, mais en 1931 Paul Dirac en a démontré l'existence théorique dans le cadre de la physique quantique. En septembre 2009, des chercheurs ont observé des quasiparticules artificielles présentant les propriétés du monopôle magnétique.
Market distortionIn neoclassical economics, a market distortion is any event in which a market reaches a market clearing price for an item that is substantially different from the price that a market would achieve while operating under conditions of perfect competition and state enforcement of legal contracts and the ownership of private property. A distortion is "any departure from the ideal of perfect competition that therefore interferes with economic agents maximizing social welfare when they maximize their own".
Plane (esotericism)In esoteric cosmology, a plane is conceived as a subtle state, level, or region of reality, each plane corresponding to some type, kind, or category of being. The concept may be found in religious and esoteric teachings—e.g. Vedanta (Advaita Vedanta), Ayyavazhi, shamanism, Hermeticism, Neoplatonism, Gnosticism, Kashmir Shaivism, Sant Mat/Surat Shabd Yoga, Sufism, Druze, Kabbalah, Theosophy, Anthroposophy, Rosicrucianism (Esoteric Christian), Eckankar, Ascended Master Teachings, etc.
