This thesis consists of a fatigue study carried out on an aluminum alloy 2024-T3 in both time domain and frequency domain. Non-zero mean random signals of strain and stress are analyzed in time domain using usual Rainflow method and the damage is accumulated with the Palmgren-Miner rule, according to mean stress equations. The signals are analyzed in frequency domain using the power spectral density and the probability density function. The spectral domain analysis does not consider the negative effect of the mean stress in metal life under fatigue, so the correction factors for mean stresses developed by Goodman, Morrow, and Smith-Watson-Topper are used to change the power spectral density ...
Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 186. Amazonia and Global Change synthesizes results of the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) for scientists and students of Earth system science and global environmental change. LBA, led by Brazil, asks how Amazonia currently functions in the global climate and biogeochemical systems and how the functioning of Amazonia will respond to the combined pressures of climate and land use change, such as Wet season and dry season aerosol concentrations and their effects on diffuse radiation and photosynthesis Increasing greenhouse gas concentration, deforestation, widespread bi...
Using detailed, empirical examples, Structural Equation Modeling, Second Edition, presents a thorough and sophisticated treatment of the foundations of structural equation modeling (SEM). It also demonstrates how SEM can provide a unique lens on the problems social and behavioral scientists face. Intended Audience While the book assumes some knowledge and background in statistics, it guides readers through the foundations and critical assumptions of SEM in an easy-to-understand manner.

This book can be divided in two major parts: the first is all about basic concepts for structural mechanics, where statics and stress analysis are introduced together with bending, torsion and transverse shear for thin-walled structures, general energy methods and numerical methods including the finite element method; the second part includes the major innovative contributions of this book, which are the structural idealisation for the modelling of aircraft structures, the buckling and spar theory, shell element analysis and the modelling with composite materials. The Matlab scripts provided in the book can be summarised as follows: 1. a full Matlab code for the modelling of the transverse s...

Religion in New Spain presents an overview of the history of colonial religious culture and encompasses aspects of religion in the many regions of New Spain. In reading these essays, it is clear the Spanish conquest was not the end-all of indigenous culture, that the Virgin of Guadalupe was a myth-in-the-making by locals as well as foreigners, that nuns and priests had real lives, and that the institutional colonial church, even post-Trent, was seldom if ever above or beyond political or economic influence. Susan Schroeder and Stafford Poole have divided the presentations into seven parts that represent general categories spanning the colonial era: "Encounters, Accommodation, and Outright Id...
