Estimation of tunnelling-induced settlement by modern intelligent methods

Application of artificial intelligence methods for estimation of maximum surface settlement caused by EPB shield tunneling

Maximum surface settlement (MSS) is an important parameter for the design and operation of earth pressure balance (EPB) shields that should determine before operate tunneling. Artificial intelligence (AI) methods are accepted as a technology that offers an alternative way to tackle highly complex problems that can’t be modeled in mathematics. They can learn from examples and they are able...

Modern Methods for Power System Harmonics Estimation

Enhanced quantum tunnelling induced by disorder

Abstract We reconsider the problem of the enhancement of tunnelling of a quantum particle induced by disorder of a one-dimensional tunnel barrier of length L, using two different approximate analytic solutions of the invariant imbedding equations of wave propagation for weak disorder. The two solutions are complementary for the detailed understanding of important aspects of numerical results on...

Relationship Between Ground Settlement Due to Tunnelling and Ground Physico-mechanical Peroperties (RESEARCH NOTES)

SAR imaging via modern 2-D spectral estimation methods

This paper discusses the use of modern 2D spectral estimation algorithms for synthetic aperture radar (SAR) imaging. The motivation for applying power spectrum estimation methods to SAR imaging is to improve resolution, remove sidelobe artifacts, and reduce speckle compared to what is possible with conventional Fourier transform SAR imaging techniques. This paper makes two principal contributio...
