BackgroundIn the field of computational biology, analyzing complex data helps to extract relevant biological information. Sample classification of gene expression data is one such popular bio-data analysis technique. However, the presence of a large number of irrelevant/redundant genes in expression data makes a sample classification algorithm work...

The main purpose of this paper is multi-objective optimization of soft-core composite sandwich plates using a known accurate high-order sandwich plate theory. In this three-layer theory, high-order kinematic assumptions are dedicated to each face sheet and the core layer. This theory considers the transverse flexibility of the soft core and satisfi...
The interest to find cost-optimal zero-energy solutions for building, using multi-objective optimization, has risen dramatically over the last decade. Accordingly, several studies have been carried out, proposing new methods and tools. None, however, has introduced a simplified approach that is viable by a broader range of users. This study address...

Gears are crucial elements in mechanical systems and contribute to the overall performance of machinery. As such, optimization of gearbox transmission systems remains a challenging problem faced by researchers and designers for numerous years. In the present work, three objectives viz volume, power output and centre-distance are investigated simult...
In the robust shape optimization context, the evaluation cost of numerical models is reduced by the use of a response surface. Multi-objective methodologies for robust optimization that consist in simultaneously minimizing the function and a robustness criterion (the second moment) have already been developed. However, efficient estimation of the r...

Fiber laser micro-channeling on polymethyl methacrylate (PMMA) workpiece has been carried out to determine the effect of process parameters as well as optimum values of the responses, i.e., cut width and depth of the fabricated micro-channels. Response surface methodology-based analysis has been carried out by conducting experiments as per experime...

Efficient, just, and sustainable water resources’ allocation is difficult to achieve in multi-stakeholder basins. This study presents a multi-objective optimization model for water resources allocation and reports its application to the Sefidrud basin in Iran. Available water resources are predicted until 2041with the artificial neural network algo...

In this paper, first, the vibrational governing equations for the suspension system of a selected sports car were derived using Lagrange's Equations. Then, numerical solutions of the equations were obtained to find the characteristic roots of the oscillating system, and the natural frequencies, mode shapes, and mass and stiffness matrices were obta...
Spolehlivostní optimalizace konstrukcí (RBDO, z anglického Reliability-based design optimization) hledá kompromisní řešení mezi cenou a spolehlivostí systému. Klasická vícekriteriální RBDO rozšiřuje jednokriteriální formulaci více účelovými funkcemi se zachováním omezujících spolehlivostních podmínek. Tato práce definuje úlohu tak, aby byla výsledn...

Wind energy has been used by humans for thousands of years. Yet, the relatively low economic cost and availability of fossil fuels upstaged the use of wind power. Fossil fuel resources are not renewable and will decline until exhaustion in the future. At the same time, humans have become aware of the adverse effects on the environment caused by rel...
