Lord Rayleigh and Ritz [1] used trial functions to approximate solutions of differential equations. Galerkin [2] used the same concept for solution. The deficiency in the past approaches [6] as compared to the
A unique multi-objective approach metaheuristic algorithm inspired from natural behaviors of hippos was utilized as an optimizer in dealing with complex truss structural optimization problems and its results indicated that it could outperform other approaches in terms of finding optimum solutions quickly32....
To address these two problems, different design solutions to make full use of the composite actions on the former issue and a structure optimization in the joint on the latter issue, namely concrete-filled rectangular hollow section (CFRHS) joint stiffened with perfobond rib (Perfobond Leister in ...
The approach presented by Prager (1974) and Parkes (1975) was originally conceived for problems based on volume minimization. The idea is to replace the real volume of the structure, given by\(V = {\sum }_{i=1}^{m} l_{i} x_{i}\)(whereliare the bars lengths), by the modified ...
Based on the results of the CGO and other approaches from the literature, the CGO can provide better and competitive results in dealing with the considered truss design problems. Conclusion In summary, the CGO can provide better solutions in dealing with the considered real-size structural design ...
Most of the structural optimization problems have multi-ple objectives in real world.Unlike the single objective opti-mization problem, the purpose of solving multi-objective optimization problem is to gain a set of non-dominated optimal solutions, also known as Pareto optimal solutions,instead of ...
The primary challenge is how to handle the complexity and self-occlusion problem of the truss geometry under the constraints of camera field-of-view (FOV), safety clearance, and flight duration. Over the past years, advanced flight planning solutions have been proposed for the automated inspection...

UK PM Liz Truss and the EU plan to impose a Putin Energy Price Cap - but with Chinese hydroelectricity running dry, and Russia sending gas to China via a pipeline, the EU has zero leverage to negotiate a discount.
Finding analytical solutions that also satisfy boundary conditions specified over arbitrary two- and three-dimensional regions becomes a very difficult task. Numerical methods are therefore widely used for solution of practical problems in all branches of engineering [3].The finite element method is one...
