Dynamic analysis of a tensegrity-based traction structure

Heping Liu, Jinxin Lu, Fusheng Zhu, Ani Luo

This study proposes a tensegrity-based traction structure with D-bar dual cable units. It is used to connect the airship and the ground to stabilize the airship.

OpenMP-based parallel MLPG solver for analysis of heat conduction

Abhishek Kumar Singh, Krishna Mohan Singh

In the present work, we focus on developing an in-house parallel meshless local Petrov-Galerkin (MLPG) code for the analysis of heat conduction in two-dimensional and…

Hybrid algorithm for global optimization based on periodic selection scheme in engineering computation

Ting Zhou, Yingjie Wei, Jian Niu, Yuxin Jie

Metaheuristic algorithms based on biology, evolutionary theory and physical principles, have been widely developed for complex global optimization. This paper aims to present a…

Parallelization of adaptive Bayesian cubature using multimodal optimization algorithms

Fangqi Hong, Pengfei Wei, Michael Beer

Bayesian cubature (BC) has emerged to be one of most competitive approach for estimating the multi-dimensional integral especially when the integrand is expensive to evaluate, and…

Multi-objective sensor placement optimization and damage identification for an aircraft wing using Lichtenberg algorithm

Felipe Sales Nogueira, João Luiz Junho Pereira, Sebastião Simões Cunha Jr

Prediction of effective equivalent linear temperature gradients in bonded concrete overlays of asphalt pavements

Charles A. Donnelly, Sushobhan Sen, John W. DeSantis, Julie M. Vandenbossche

The time-varying equivalent linear temperature gradient (ELTG) significantly affects the development of faulting and must therefore be accounted for in pavement design. The same…
