NASTRAN buckling study of a linear induction motor reaction rail
NASTRAN was used to study problems associated with the installation of a linear induction motor reaction rail test track. Specific problems studied include determination of the critical axial compressive buckling stress and establishment of the lateral stiffness of the reaction rail under combined loads. NASTRAN results were compared with experimentally obtained values and satisfactory agreement was obtained. The reaction rail was found to buckle at an axial compressive stress of 11,400 pounds per square inch. The results of this investigation were used to select procedures for installation of the reaction rail
Holographic stress analysis
Device for nondestructive testing of soldered joints correlates stress with load to predict printed circuit board lifetime
Orbital tube flaring system produces tubing connectors with zero leakage
An orbital tube flaring system produces tubing connectors with a zero-leak potential needed in high pressure hydraulic and pneumatic systems. The flaring system incorporates a rolling cone and rolling die to closely control flare characteristics
Impact of specific CSR activities, executive & board diversity on equity valuations
Thesis (M.S.) University of Alaska Fairbanks, 2018The objective of this study is to identify the impact of specific corporate social responsibility behaviors on equity prices. This study uses fixed effect parametric and nonparametric regressions to quantify the effect of specific corporate social responsibility activities on the equity price multiples of a number of US firms from 1999 to 2009. The results of these empirical models consistently show that CEO diversity, corporate charitable giving, and work-life balance benefit plans, are associated with lower equity price multiples compared against similar firms that lack these characteristics. Additionally, board diversity and support of the LBGTQ community is associated with a positive impact on equity price multiples. This study provides evidence that individual corporate social responsibility activities can have drastic impacts on equity prices, leading the way for future research testing whether the magnitudes of these impacts are rational and in-line with their expected impact on financial performance and risk, or a deviation from the efficient market hypothesis
