“…We set the converged factor (RR in [6]) to 0.75 and the iteration steps to 60 in this example so that the converged value can be reduced less than 0.002. e OA (81, 20, 3, 2) is formed by extracting the first 20 columns of the OA (81, 40, 3, 2) which is obtained from [24]. e fitness function can be also described as (3) and (4).…”

“…Taguchi method, also called as Taguchi's method, was proposed by Professor Taguchi in 1967. As a means of product quality control and optimization in the early stage, it was soon spread [1][2][3][4][5]. is method is a feasible way to avoid the full factorial experiment of testing all combinations of parameters in an experiment, which means it can obtain the excellent and stable products by using as few test times as possible, and it is conducive to improving the rate of good products in the meanwhile.…”

In this paper, a Taguchi method based on fitting and prediction is proposed to accelerate the optimization process in antenna array synthesis. The implementation procedure combines the normal Taguchi method and the curve fitting technique. A possible solution is determined by prediction based on fitting curves. Specifically, the fitting curves are obtained by using the dynamic points calculated and updated as the Taguchi method progress and recorded in the response table necessarily produced in the procedure. Test functions are used for conducting some confirmation experiments, and the results verify the validity of the proposed method. In order to illustrate its good practicability, two linear antenna arrays with a null controlled pattern and a flat top pattern, respectively, are successfully optimized by using both of the normal Taguchi method and the proposed one. Some comparisons and discussions of their results are given in the paper, which proves that the proposed method has a better practicability, not only because it inherits the global optimization characteristics of the normal Taguchi method but also because it accelerates the convergence process.

“…Silicon-Based structural ceramics are often considered to be the ideal wave-transparent and electrical insulating material under high temperature conditions because of their excellent properties such as high tolerance to mechanical stress, good thermal stability, low dielectric constant and high electrical resistivity [1–3]. The use of continuous silicon nitride fibers as a reinforcement enables ceramic matrix composites to have much higher damage tolerance than monolithic ceramics [4,5].…”

The aim of this study executed on Silicon Nitride (Si3N4) yarn is to examine some bending damage behaviors and fracture mechanisms that occur during the 3D orthogonal fabric forming process. A three point bending experiment device has been developed in order to simulate the Z-binder yarn bending condition. The effects of weft density, fabric thickness, and yarn tension have been studied. The Weibull analysis of the tensile strength show that the bending damage increases with the increase of weft density, fabric thickness, and yarn tension. The resulting bending damage causes a reduction in yarn strength of between 2.5 and 17.2% depending on the bending parameters of yarn. The growth of the fibrillation area also reflects similar trends with tensile strength loss rate. The fibrillation length produced by the yarns is mostly distributed within the range of 0.3 to 0.9 mm. A comparison of the calculation result to experimental data shows the bending fracture probability of filaments inside yarn are less than that of monofilament. The tensile and bending fracture of Si3N4 filaments exhibit typical brittle fracture characteristics.
