LeTourneau modified tank-tree crusher with R.G. LeTourneau and unidentified man.
No full textPhotograph of a Tree Crusher Tender built in Vicksburg, Mississippi and intended for use at the Tournata complex in Liberia, according to author Eric Orlemann. Shown with the tank are R.G. LeTourneau, left, and an unidentified man. The tank was never actually shipped to Tournata
Longview manufacturing plant under construction, LT21 Misc Photos Archive 062.
No full textPhotograph of the Longview manufacturing plant of R.G. LeTourneau, Inc. The plant's construction began in 1945 and completed in 1946. At the time, according to Otis Hays, author of R.G. LeTourneau: Move of Men and Mountains, at the time it was the world's largest welding and manufacturing plant under one roof, covering more than 100 acres
Influence of forward and backward travelling reflections on the gain and ASE spectrum of EDFAs
No full textOptical reflections at the input of an optical amplifier increase the noise more than those at the output. Measurements with 21 dB gain and 21 dB return lose indicate that an optical isolator at the input improves the noise figure by 3 dB more than one at the output
The Big Plow with 6-Foot Disc, J5G, Photo 35, L-8312
No full textPhotograph of R.G. LeTourneau's Series H (Model 6-16) Disc Plow, designed for land-clearing operations. It was powered by a front longitudinally mounted diesel, according to author Eric Orlemann
Large LeTourneau tree crusher, LT20
No full textPhotograph of aLeTourneau tree crusher with three unidentified men. This is likely the Series G-50 Tree Crusher, judging from a similar photo in author Eric Orlemann's book on R.G. LeTourneau's earthmoving equipment
The Added Value of Enterprise Architecture
No full textApplying architecture implies that it provides added value across an enterprise. Although widely adopted, this claim has only been scarcely investigated, not to mention quantified. This document describes the results of a case study to quantify the effects of applying Enterprise Architecture within a financial institution called FinCom. For confidential information reasons, the name of this company is fictive. The thesis attempts to capture several factors at project level with respect to the application of Enterprise Architecture and its subsequent financial benefits. The study analyzed 40 projects, with regard to time and budget overrun. In order to collect these data, a total of 35 business, enterprise and domain architects were interviewed on their experience with these projects. Among factors taken into account were architecture type, project compliance to architecture and experience of the architect. Consequently, these factors are recorded in hypotheses that relate to the budget and time figures of the project. These hypotheses are incorporated in the 'Architecture Effectiveness Model' and statistically tested with the acquired data. This led to more than 12.000 calculations to show the subsequent benefits of Enterprise Architecture.Information ArchitectureComputer ScienceElectrical Engineering, Mathematics and Computer Scienc
Side-Dump Train, built by R.G. LeTourneau, Inc.
No full textPhotograph of the LeTourneau Side-Dump Train designed as a bulk-material hauler. According to author Eric Orlemann, this model consisted of a 6-wheel tractor and two 6-wheel trailers. Only one example was ever built
Thermodynamic Properties of Liquid Iron-Chromium-Oxygen Alloys
No full textTitle: Thermodynamic Properties of Liquid Iron-Chromium-Oxygen Alloys, Author: Stanely Y. Shiraishi, Location: ThodeIn this thesis the equilibrium between H2/H2O gas mixtures and iron-chromium melts was measured over a wide range of temperatures, 1470 - 1750°C. Specimens were levitated in selected H2/H2O gas mixtures, quenched and analyzed for oxygen. The gas composition fixed the oxygen potential in the system and allowed the thermodynamics of the oxygen solution reaction to be determined. Wagner interaction parameters were employed to describe the degree of chemical interaction between chromium and oxygen.ThesisMaster of Science (MS

Early Carolingian: Italy
No full textThis chapter surveys the use of Early Carolingian minuscule script in Italy. It discusses the transition from various Pre-Caroline cursive bookscripts to a distinctive Italian variant of the Carolingian hand, which occurred gradually after Charlemagne’s conquest of Italy in 774. The author also evaluates the spread of the script through Northern and Central Italy during the ninth and into the tenth century
