Unified soil classification system. This system evolved from the airfield classification system after modifications by A. Casagrande of Harvard University and the US Bureau of Reclamation and the Corps of Engineers. It classified soil into three general groups-i. e. coarse-grained, fine-grained and highly organic, with a further fifteen categories depending on gradation of the coarse-particled soils and plasticity of the fine-grained soils. 6, record 1, English, - unified%20soil%20classification%20system

Il existe de très nombreux systèmes de classification des sols [...] On retiendra [...] la classification des Laboratoires des Ponts et Chaussées ou classification L.P.C. qui n'est autre que la classification U.S.C.S. (Unified Soil Classification System) après adaptation aux seuils granulométriques utilisés en France. On rappellera que la classification U.S.C.S. est elle même dérivée de celle de Casagrande. 1, record 1, French, - classification%20U%2ES%2EC%2ES%2E

The Harvard classification was based on gradations in the patterns of the spectral lines and was independent of theoretical considerations. The sequence is characterized particularly by the rise and decline in the strength of the hydrogen lines throughout its extent. 1, record 2, English, - Harvard%20classification

Le critère quantitatif de l'appartenance de l'étoile à telle ou telle classe ou sous-classe spectrale est donné par le rapport des intensités des raies définies. Ce principe a été appliqué avec succès au début du XXe siècle à l'observatoire de Harvard. La classification de Harvard est à la base de la classification spectrale moderne. Les classes spectrales de la classification de Harvard sont désignées par les lettres W, O, B, A, F, G, K, M. 1, record 2, French, - classification%20de%20Harvard
