Abstract: An accelerogram-based method is developed and validated for the quick assessment of liquefaction occurrence based on ground motion records. In this method, two frequency-related ground motion indices, termed RL and MIFr, ...

Abstract: In order to analyze the unsteady aerodynamic response of compressors with limited computational resources, the development of the body force (BF) model has been pursued for decades. This model can simulate the effects of ...

Abstract: To stabilize the terminal normal shock on highstatic pressure at outlet, called backpressure pout, stability bleed slots are used in the throat of mixedcompression supersonic inlets. In this paper, a model for the functional ...

Abstract: Understanding and assessing the spatial extent of liquefaction requires that the spatial dependence of soil properties to be taken into account. In this work, a cone penetration test (CPT)-based approach for the evaluation ...

Abstract: This paper examines further the problem of deducing the wind field from vorticity and divergence over a limited area with prescribed winds at the boundary. An earlier work showed that the wind field in a limited area can ...

Abstract: In σ coordinates, a variable ?e(x, y, σ, t) whose horizontal gradient ???e is equal to the irrotational part of the horizontal pressure gradient force is referred to as an equivalent isobaric geopotential height. Its inner ...

Abstract: A harmonic-sine series expansion for a function in two-dimensional space is proposed to be a sum of two parts. The harmonic part is the solution of the Laplace equation with prescribed boundary values of this function. The ...

Abstract: Axial-flow compressors work against varying inlet boundary layers in real working conditions and are therefore required to perform well and robustly. This paper presents a surrogate-based optimization procedure applied to ...

Abstract: China is actively building urban utility tunnels and incorporating gas pipes into the tunnels. However, there is a certain risk of leakage and explosion when gas enters the tunnels. If the gas pipe leaks and causes an ...

Abstract: This study depicts a scenario where vulnerability to soil liquefaction leads to the deterioration of a city-scale traffic system shortly after an earthquake. A novel framework for evaluating city-scale traffic performance ...
