Study of Load Calculation Models for Anti-Sliding Short Piles Using Finite Difference Method

Applied Sciences, 2023
Anti-sliding short piles, a novel technique for slope stabilization, have been applied in engineering practices. Nonetheless, a mature structural calculation theory for these piles is still lacking.

Classical Ising model test for quantum circuits

, 2009
We exploit a recently constructed mapping between quantum circuits and graphs in order to prove that circuits corresponding to certain planar graphs can be efficiently simulated classically.

Study on the Optimized Perception of Structural Behavior in Shield Tunneling by Fiber Grating Layouts

Buildings
Shield tunnels’ structural stability is challenged due to the fact that they are often built under rivers, lakes, and oceans. It is crucial to execute the structural deformation perception of the shield tunnel.

Morphological Evolution of Passive Soil Arch in Front of Horizontal Piles in Three Dimensions

Buildings, 2022
The anti-slide pile is a primary method of landslide control. The effect of the passive soil arch in front of the embedded section of piles has a significant effect on the anti-slide pile’s bearing capacity.

A test for model specification of diffusion processes

, 2008
We propose a test for model specification of a parametric diffusion process based on a kernel estimation of the transitional density of the process. The empirical likelihood is used to formulate a statistic, for each kernel smoothing bandwidth, which is ...

Analysis of Multilayered Ground Amplification Characteristics by Scaled-Down Model Tests

Applied Sciences, 2022
During an earthquake, seismic waves travel through different media through the source to reach the surface. It is very necessary to study the dynamic characteristics of soil between different layers during earthquake.

Testing Conditional Factor Models [PDF]

SSRN Electronic Journal, 2009
We develop a new methodology for estimating time-varying factor loadings and conditional alphas based on nonparametric techniques. We test whether long-run alphas, or averages of conditional alphas over the sample, are equal to zero and derive test statistics for the constancy of factor loadings. The tests can be performed for a single asset or jointly
