Determining optimal parameters

In this paper, the calculation was done to determine the magnetic exchange of the studied molecules, Schiff base complexes via DFT calculations. Using the ZORA approach with the BP86 functionals and appropriate basis set def2-tzvp and Coulomb fitting, the optimized geometries were obtained with reliable accuracy and precision. The dipole moment was calculated.

The paper analyzes and determines the optimal parameters of tuned mass damper to reduce torsional vibration for the machine shaft. The research steps are as follows. First, the optimal parameters of tuned mass damper for the shafts are given by using the maximization of equivalent viscous resistance method. Second, a numerical simulation is performed for configuration of machine shaft to validate the effectiveness of the obtained analytical results.

This paper aims to apply the developed ADE to optimize truss structures subjected to frequency constraints. In addition, limitations of the AOA are also discussed, as well as how to overcome them. In each iteration, a randomly generated probability parameter is used to determine whether AOA or DE that would be used to generate new candidate solutions in the population.

In this study, 341 Bacillus sp. strains were isolated from agricultural soils of Turkey. The potent extracellular lipase producer was selected. It was identified by 16S rRNA, named as Bacillus cereus ATA179. Optimal nutritional and physical parameters for lipase production were determined. Sucrose as the carbon source, (NH4 )2 HPO4 as the nitrogen source, CaCl2 as the metal ion were obtained. The best results of physical parameters were stated at 45°C, pH 7.0, shaking rate 50 rpm, inoculation amount 7% and inoculum age 24 h.

The experiment was conducted to investigate the embryonic development of discus (Symphysodon aequifasiatus) and determine the time required for major egg developmental stages and hatching. Regular observations were made using optical microscope and the images were recorded using a digital camera attached to the microscope. Important water quality parameters were kept optimal for the hatching of discus eggs.
