Nonlinear solutions of lateral response for piles under axial and lateral load embedded in layered soils

地质科技通报, 2021
Most of the previous studies were based on the linearly elastic or linearly elastic-plastic horizontal load transfer model for the laterally loaded piles undergoing axial load.In order to improve the calculation and design accuracy of axially and ...

Model reduction for complex hyperbolic networks [PDF]

2014 European Control Conference (ECC), 2014
We recently introduced the joint gramian for combined state and parameter reduction [C. Himpe and M. Ohlberger. Cross-Gramian Based Combined State and Parameter Reduction for Large-Scale Control Systems. arXiv:1302.0634, 2013], which is applied in this work to reduce a parametrized linear time-varying control system modeling a hyperbolic network.

An Extension of Poincare Model of Hyperbolic Geometry with Gyrovector Space Approach [PDF]

Mathematics Interdisciplinary Research, 2016
‎The aim of this paper is to show the importance of analytic hyperbolic geometry introduced in [9]‎. ‎In [1]‎, ‎Ungar and Chen showed that the algebra of the group SL(2, C) naturally leads to the notion of gyrogroups ‎and gyrovector spaces for dealing ...
