Book excerpt: L'objectif de ces travaux de thèse est d'étudier le comportement thermique des engrenages en fonctionnement marginal de lubrification. Ces phases se caractérisent par une quantité faible ou inexistante d'huile apportée aux éléments lubrifiés. Le fonctionnement ciblé fait intervenir uniquement de l'huile résiduelle des précédentes lubrifications dans un contexte de faibles puissances transmises. Le fonctionnement sera étudié du point de vue de la modification des échanges thermiques, des pertes de puissance générées et de la modification des états de surface des dents. Pour cela, une approche expérimentale sur un banc engrenage modifié pour ces conditions de lubrification a été menée. Il a été observé que le fonctionnement marginal influençait à la fois les échanges thermiques et les pertes de puissance générées au sein du système. Une modélisation thermique nodale du banc d'essai a permis de comprendre la modification des échanges thermiques et d'isoler les pertes par frottement à la denture lors du fonctionnent marginal. Pour aller plus loin, une étude du fonctionnement sous-alimenté à l'échelle du contact a été menée sur machine bi-disques. Une méthode semi empirique d'estimation de l'épaisseur de film d'huile dans le contact a permis de mettre en évidence que le temps disponible avant la défaillance dépendait de phénomènes de réalimentation du contact. D'ailleurs, des essais réalimentés régulièrement ont montré qu'une très faible quantité de lubrifiant état nécessaire à la lubrification du contact, mais n'assurait pas le rôle de refroidissement.

Book Synopsis The Princeton Encyclopedia of Classical Sites by : Richard Stillwell
Download or read book The Princeton Encyclopedia of Classical Sites written by Richard Stillwell and published by Princeton University Press. This book was released on 2017-03-14 with total page 1068 pages. Available in PDF, EPUB and Kindle. Book excerpt: Here are over 1,000 pages of authoritative information on the archaeology of Greek and Roman civilization. The sites discussed in the more than 2,800 entries are scattered from Britain to India and from the shores of the Black Sea to the coast of North Africa and up the Nile. They are located on sixteen area maps, keyed to the entries. The entries were written by 375 scholars from sixteen nations, many of whom have worked at the sites they describe. Until now our knowledge of the Classical period has been scattered in hundreds of sources dating from antiquity to our own times. This volume provides essential information on work accomplished, in progress, and still to be undertaken. Originally published in 1976. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Available in PDF, EPUB and Kindle. Book excerpt: "According to one myth, the first Athenian citizen was born from the earth after the sperm of a rejected lover, the god Hephaistos, dripped off the virgin goddess Athena's leg and onto fertile soil. Henceforth Athenian citizens could claim to be truly indigenous to their city and to have divine origins that bypassed maternity. In these essays, the renowned French Hellenist Nicole Loraux examines the implication of this and other Greek origin myths as she explores how Athenians in the fifth century forged and maintained a collective identity."--Publisher's description.
Book Synopsis Non-Slave Labour in the Greco-Roman World by : Peter Garnsey
Download or read book Non-Slave Labour in the Greco-Roman World written by Peter Garnsey and published by Cambridge Philological Society. This book was released on 2020-08-30 with total page 105 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Greco-Roman society the typical labourer was a peasant, not a slave. Yet, while specialized studies of ancient slavery abound, the subject of free labour, its incidence, status and economic significance, has received little attention. This volume of essays provides a summary of the available evidence for non-slave labour in antiquity and a bibliographical guide, but in addition advances novel interpretations concerning, for example, the composition of the 'labouring class', the relation between slave and peasant systems of production, and the importance of free dependent labour in the Western Roman provinces.

Book excerpt: The Conference Proceedings contains 38 papers presented at the Propulsion and Energetics Panel 73rd Symposium on 'Aircraft Fire Safety' which was held 22 - 26 May 1989 in Sintra, Portugal. The Symposium was arranged in the following sessions: Review of Fire-Related Aircraft Accidents (3); Fire Safety Standards and Research Programmes (6); Aircraft Internal Fires (9); Aircraft External Fires (2); Fire Safety of Military Weapon Systems (3); Fire Hardening by Advanced Materials and Structural Design (8); Passenger Behaviour in Emergency Situations (3); and Passenger Protective Equipment (4). The Technical Evaluation Report and and Addendum are included at the beginning of the Proceedings. Questions and answers of the discussions follow each paper. The last AGARD review on the subject took place in a Specialists' Meeting in 1975, followed by a Working Group Report in 1979 and Lecture Series in 1982. The purpose of the Symposium was a review of the present state-of-the-art and of the last improvements. Although the safety standards in aviation are already very high, there is still room for improvements. They are listed in the Conclusions and Recommendations of the Technical Evaluation Report and in the Addendum.
