S-2 Span Damage - Supplementary Materials for the Report: Effects of Realistic Heat Straightening Repair on the Properties and Serviceability of Damaged Steel Beam Bridges


Amit H. Varma, Young Moo Sohn


Guidelines for conducting heat straightening repair have been developed by FHWA and many DOTS. The guidelines establish limits for: (a) the maximum damage that can be repaired, (b) the maximum restraining force, and %(c%) the maximum heating temperature to...

Agricultural Advisors’ Climate Risk Perceptions: 2013 Survey Data


Amber Mase, Cody Knutson, Jean McGuire, Linda S. Prokopy, Lois Morton, Maria Lemos, Melissa J. Widhalm, Stuart Carlton, Tonya Haigh


Agricultural advisors in four Midwestern states (Indiana, Iowa, Michigan, and Nebraska) were surveyed (via email) in February 2013 about their climate risk perceptions, climate change beliefs, and willingness to use climate information. This survey was a f...

MCD: Matlab programs for computing the Macdonald function for complex orders


Walter Gautschi


The use of Gaussian quadrature formulae is explored for the computation of the Macdonald function (modified Bessel function) of complex orders and positive arguments. It is shown that for arguments larger than one, Gaussian quadrature applied to the integr...

OWF: Matlab programs for computing orthogonal polynomials with respect to densely oscillating and exponentially decaying weight functions


Walter Gautschi


Software (in Matlab) is developed for computing variable-precision recurrence coefficients for orthogonal polynomials with respect to the weight functions 1 + sin(1/t), 1 + cos(1/t), e^-1/t} on [0,1], as well as e^-1/t-t} on [0, infinity] and e^-1/t^2 - t^...

CHA: Matlab programs for computing a challenging integral


Walter Gautschi


Standard numerical analysis tools, combined with elementary calculus, are deployed to evaluate a densely and wildly oscillatory integral that had been proposed as a computational problem in the''SIAM 100-Digit Challenge''. Numerical results...

BIJ: Matlab programs for testing and extending Bernstein's Inequality for Jacobi polynomials


Walter Gautschi


Bernstein’s inequality for Jacobi polynomials with parameters alpha, beta is analyzed here analytically and, above all, computationally with regard to validity and sharpness. Computation suggests that the inequality holds with new, somewhat larger, constan...

CIZJP: Matlab programs for conjectured inequalities for zeros of Jacobi polynomials


Walter Gautschi


Inequalities for the largest zero of Jacobi polynomials, conjectured recently by us and in joint work with P. Leopardi, are here extended to all zeros of Jacobi polynomials, and new relevant conjectures are formulated based on extensive computation.

GQLOG: Matlab routines for computing Gauss Quadrature rules with logarithmic weight functions


Walter Gautschi


By means of the Matlab symbolic/variable-precision facilities, routines are developed that generate an arbitrary number of recurrence coefficients to any given precision for polynomials orthogonal with respect to weight functions of Laguerre and Jacobi typ...
