Abstract: Historical and economic influences on bridge design, including the effects of the Great Depression and World War II, are reviewed. The conditions under which a bridge is built and will serve are also examined in regard to ...

Abstract: This paper describes a method for estimating the dynamic characteristics of electromagnetic relays. The equations of motion are formulated based on a constant core reluctance model magnetic circuit ...

Abstract: A method for the driving torque, shaking moment, and shaking force balancing is given as individual or combined problems for all of the four-link mechanisms: the four-bar, the slider-crank, the ...

Abstract: This paper describes the results of a field experiment at the Goodnoe Hills, Wash. site to examine the effects of trees on wind flow variability and turbulence. Although vegetation at the ...

Abstract: In this paper analysis results for a 2D solid oxide fuel cell model are presented. The model is solved on an unstructured mesh with the finite-volume scheme using an iterative Newton’s method. ...

Abstract: Two simple models are developed to predict the advance rate of flow in furrows. The first model is developed using a modified version of Muskingum flood‐routing techniques. The second model is developed by assuming that ...

Abstract: Sensitivity analysis and design optimization of solid oxide fuel cells are presented. Multispecies diffusion, low speed convection, and chemical kinetics are included in a two-dimensional numerical ...

Abstract: The effect on the stability of a dynamically loaded journal bearing of introducing a pressure step is examined by calculating numerically the whirl orbits described by the journal for a range ...

Abstract: Dynamically loaded rotor bearings are frequently observed to perform whirling motions, in which the center of the rotor describes some sort of closed orbit. In this paper we demonstrate, by ...
