TL;DR: In this paper, Lerdahl and Jackendoff test the abstraction of two forms of underlying structures: reduced structure and long-term structure, based on the work of Lerding and Jørgenson.
Abstract: This experiment, based on the work of Lerdahl and Jackendoff (1983), was designed to test the abstraction of two forms of underlying structures: "reduced structure" and "prolongational structure". ...

TL;DR: In this paper, a method based on emission absorption of thermal radiation in the near infrared between 1 and 5 μm is proposed to determine the local temperatures of coal flames. But the method is not suitable for the measurement of coal fires and the results obtained are generally between those determined for the particle and gas respectively.
Abstract: The method described is based on emission-absorption of thermal radiation in the near infrared
between 1 and 5 μm. Unlike conventional optical methods, it allows the determination of local temperatures
rather than an average temperature integrated along aiming line of the pyrometer. The particle and gas
temperature radial fields together with the relative particle concentration radial fields in a semi-industrial
pulverized coal flame have been established. The distributions which have been obtained show that industrial
flames are neither isothennal nor homogeneous. Particle and gas temperature profiles exhibit the same shape
but particle temperatures are about 100°C higher than gas temperatures. Measurements have also been made
with a suction pyrometer and the results obtained are generally found between those determined for the
particules and gases respectively.
