Roster of heads of families in 1790, so far as can be shown from records of the Census Office. The returns for Delaware, Georgia, Kentucky, New Jersey, Tennessee and Virginia were destroyed by fire in 1814. --Cf. introd.
This schedule represents a complete list of the heads of families in North Carolina at the time of the adoption of the Constitution. Under law, the marshals were required to ascertain the number of inhabitants within their respective districts, omitting Indians not taxed, and distinguishing free persons (including those bound to service for a term of years) from all others; the sex and color of free persons; and the number of free males 16 years of age and over. The object of the inquiry last mentioned was, undoubtedly, to obtain definite knowledge as to the military and industrial strength of the country.
"The 2016 Nobel Laureate in Literature has eloquently characterized the coal situation today: "The times they are a-changin'." On or about December 2010, the coal industry worldwide seemed to be in great shape. Global demand for coal had not only recovered from the 2008 recession, but was by then expanding at annual rates"--
Non-destructive Testing of Impact Damage in Fiber-reinforced Polymer Composites: Fundamentals and Applications provides detailed knowledge on the fundamentals and applications of frequently used nondestructive testing (NDT) techniques utilized to assess impact damage in composite structures. This book starts with an introduction to impact damage in composite structures, each subsequent chapter focuses on evaluating damage using specific NDT methods. Chapters 2–4 concentrate on vision-based NDT methods such as visual inspection, digital image correlation, and digital shearography. Following this, Chapters 5–6 delve into ultrasound-based methods, including acoustic emission and phased-arra...
A motivation for structural health monitoring. Structural health monitoring of aircraft structures. Vibration-based damage diagnosis and monitoring of external loads.Statistical time series methods for vibration based structural health monitoring. Fiber optic sensors. Damage localisation using elastic waves propagation methods experimental techniques. Application for wind turbine blades. Experts actively working in structural health monitoring and control techniques present the current research, areas of application and tendencies for the future of this technology, including various design issues involved. Examples using some of the latest hardware and software tools, experimental data from small scale laboratory demonstrators and measurements made on real structures illustrate the book. It will be a reference for professionals and students in the areas of engineering, applied natural sciences and engineering management.
