Examples of Hertzian waves in a sentence
To use recursive types it is necessary to add the rule A € e : τ € τ = τ j A € e : τ j (Equal) for simple typing with recursive types [CC91] orA € e : τ € τ ≤ τ j A € e : τ j (Subtype)for simple subtyping with recursive types [AC91, AC93].
From a technological perspective, television was conditioned in its early days by the limitations of the radio spectrum and the technical characteristics of transmission by Hertzian waves.
Private experimental stationmeans a radio station utilizing Hertzian waves in experiments with a view to the development of the science and technique of radiocommunications, but does not include an amateur station.
In the mid-1980s the problematic terrain and the initiative of entrepreneurs to avoid technical problems in the dissemination of the television signal via Hertzian waves led to the development of a business model of local cable TV, which not only prevails but also has experienced a significant growth.
Overall, it is also almost certain that changes in exposure to Hertzian waves (telephony and wireless telegraphy, whether or not limited to local events) triggered Poliomyelitis epidemics in Sweden between 1876 and 1911.
When the Eiffel Tower was menaced with destruction, Poincaré backed a plan to employ it as the world’s tallest wireless transmission antenna (Galison 2003, 276), thereby strengthening the tower’s chances for preservation.Poincaré knew that Hertzian waves propagate in the ether with the speed of light, c.
Unlike other researchers of the day, his system did not use spark gaps and it is suggested that the medium of the signal was not the normal electromagnetic waves (Hertzian waves) of today’s radio, but used either capacitance and later “earth magnetic waves”.
Since Heinrich Hertz’s discovery of electromagnetic waves in air in the late 1880s, Poincaré had contributed to the theory of Hertzian waves, and engaged with the emerging technology of wire- less telegraphy.
Private experimental station means a radio station utilizing Hertzian waves in experiments with a view to the development of the science and technique of radiocommunications, but does not include an amateur station.
Terrestrial Free TV means over-the-air broadcast by Hertzian waves of a Motion Picture Copy for television reception in private living places without a charge to the viewer for the privilege of viewing the Motion Picture, provided that for this purpose government television assessments or taxes (but not a charge for PayPerView or Pay TV) will not be deemed a charge to the viewer.
