Book Review of Confederate Outlaw: Champ Ferguson and the Civil War in Appalachia
No full textReview of: Confederate Outlaw: Champ Ferguson and the Civil War in Appalachia. By Brian D. McKnight. Conflicting Worlds: New Dimensions of the American Civil War. (Baton Rouge: Louisiana State University Press, 2011. Pp. [xvi], 252. $34.95, ISBN 978-0-8071-3769-7.)
Excerpt:
Civil War scholars have produced a number of noteworthy studies of guerrilla warfare in recent years. These historians have reassessed the origins of guerrilla violence, its impact on local communities, its role in the overall war effort, and some of its notorious figures. In Confederate Outlaw: Champ Ferguson and the Civil War in Appalachia, Brian D. McKnight addresses not only the infamous guerrilla Champ Ferguson but also the larger context of the war in southern Appalachia. The author argues that fluid loyalties, extreme paranoia, and opportunism defined Ferguson\u27s war in the Upper Cumberland region [...

High-Performance Medicine: Lessons Learned from Navy SEALs and World Class Performers
No full textFilmed at the 2018 STS Annual Meeting in Fort Lauderdale, Florida, Tom Nguyen of the University of Texas Houston interviews former Navy SEAL Brian Ferguson of Arena Labs about the pursuit of performance excellence in medicine, and particularly in the realm of cardiothoracic surgery. They discuss how to handle high levels of stress and anxiety in order to optimize one's performance, and how to obtain relevant training for surgeons and their teams both effectively and affordably
Structural vibration analysis with random fields using the hierarchical finite element method
No full textElement-based techniques, like the finite element method, are the standard approach in industry for low-frequency applications in structural dynamics. However, mesh requirements can significantly increase the computational cost for increasing frequencies. In addition, randomness in system properties starts to play a significant role and its inclusion in the model further increases the computational cost. In this paper, a hierarchical finite element formulation is presented which incorporates spatially random properties. Polynomial and trigonometric hierarchical functions are used in the element formulation. Material and geometrical spatially correlated randomness are represented by the Karhunen–Loève expansion, a series representation for random fields. It allows the element integration to be performed only once for each term of the series which has benefits for a sampling scheme and can be used for non-Gaussian distributions. Free vibration and forced response statistics are calculated using the proposed approach. Compared to the standard h-version, the hierarchical finite element approach produces smaller mass and stiffness matrices, without changing the number of nodes of the element, and tends to be computationally more efficient. These are key factors not only when considering solutions for higher frequencies but also in the calculation of response statistics using a sampling method such as Monte Carlo simulation
Wave propagation in slowly varying waveguides using a finite element approach
No full textThis work investigates structural wave propagation in one dimensional waveguides with randomly varying properties along the axis of propagation, specifically when the properties vary slowly enough such that there is negligible backscattering, even if the net change is large. Wave-based methods are typically applied to homogeneous waveguides but the WKB (after Wentzel, Kramers and Brillouin) approximation can be used to find a suitable generalisation of the wave solution in terms of the change of phase and amplitude but is restricted to analytical solutions. A wave and finite element (WFE) approach is proposed to extend the applicability of the WKB method to cases where no analytical solution of the equations of motion is available. The wavenumber is expressed as a function of the position along the waveguide. A Gauss-Legendre quadrature scheme is subsequently used to obtain the phase change, while the wave amplitude is calculated using conservation of power. The WFE method is used to evaluate the wavenumbers at each integration point. Moreover, spatially correlated randomness can be included in the formulation by random field properties and in this paper is expressed by a Karhunen-Loève expansion. Numerical examples are compared to a standard FE approach and to available analytical solutions. They show good agreement when compared to either a full FE or analytical solution and require only a few WFE evaluations, providing a suitable framework for efficient stochastic analysis in waveguides
Wave propagation in slowly varying one-dimensional random waveguides using a finite element approach
No full textThis work investigates structural wave propagation in one-dimensional waveguides with randomly varying material and geometric properties along the axis of propagation, specifically when the properties vary slowly enough such that there is negligible backscattering due to any changes in the properties of the medium. This variability plays a significant role in the so-called mid-frequency region, but wave-based methods are typically only applied to homogeneous and uniform waveguides. The WKB (after Wentzel, Kramers and Brillouin) approximation can be used to find a suitable generalisation of the wave solution in terms of the change of phase and amplitude of a wave propagating through a non-uniform waveguide, but it is typically restricted to analytical solutions of the equation of motion. In this paper a Wave and Finite Element (WFE) approach is proposed to extend the applicability of the WKB method to cases where no analytical solution is available. The wavenumber is expressed as a function of the position along the waveguide and a Gauss-Legendre quadrature scheme is used to the numerically integrate the phase. The WFE method is used to evaluate the wavenumbers at each integration point, and these are kept to a minimum to minimise computation cost while being able to capture the non-homogeneity to a given accuracy. The wave amplitude is calculated using conservation of power flow. The numerical example of a straight rod with a single propagating wave mode is considered. Random field properties are expressed in terms of a Karhunen-Loeve expansion. The forced response to a point excitation is calculated and results are compared to a standard Finite Element (FE) approach and to the WKB analytical solution. Results show good agreement and require only a few WFE evaluations, providing a suitable framework to account for spatially correlated randomness in waveguides
