There are two popular methods concerning the optimal design of structures. The first is the minimization of the volume of the structure under stress constraints. The second is the minimization of the compliance for a given volume. For multiple load cases an arising issue is which energy quantity should be the objective function. Regarding the sizing optimization EPSRC grant EP/E004547/1. A. Mak...

Quantifying the relevance of different plant traits for yield and quality under different growth conditions can improve the efficiency of a breeding programme. Crop models are powerful tools to give guidance to breeding, because model calculations enable the analysis of many different situations (sensitivity analysis and scenario studies). Three case studies of using crop growth models to evalu...

3. Introduction In structural and mechanical design, deterministic design optimization models have been successfully developed. Recently, the robust structural design has received increasing attention. Based on stochastic uncertainty models of mechanical parameters, various techniques were proposed for evaluation and estimation of failure probabilities [7, 11], that can be utilized in the relia...

In this article, a new method of increasing the efficiency combined steel roof trusses is proposed and considered. A rational shape truss, including its topology geometric parameters, was obtained, but without obtaining SSS. provides adjustment SSS in truss by changing upper belt panel length. On basis obtained structural form proposed. It shown that thanks to method, it possible obtain more ef...

A robust truss optimization scheme, as well as an optimization algorithm, is presented based on the robustness function. Under the uncertainties of external forces based on the info-gap model, the maximization problem of robustness function is formulated as the optimization problem with infinitely many constraint conditions. By using a semidefinite relaxation technique, we reformulate the prese...
