In the present work, Taguchi method was used for the optimization of geometric parameters for double pin joint configurations. The orthogonal array, the signal-to-noise ratio, and analysis of variance were employed to study the effect of geometric parameters on the bearing strength of the joints. Geometric parameters, i.e. the distance from the free edge of the specimen to the diameter of the first hole (E/D) ratio, width of the specimen to the diameter of the hole (W/D) ratio, the distance between the two holes to the diameter of the hole (P/D) ratio and side width to the diameter of the hole (K/D) ratio were investigated for the serial and parallel hole configurations. The results demonstrate that the E/D ratio is the most significant parameter to increase the bearing strength in both serial and parallel pin joint configurations. Its percentage contribution is about 84.5% and 64.23% in serial and parallel pin joint configurations, respectively. Characteristic curve with Tsai–Wu failure criterion was used for the prediction of the bearing strength in the joints numerically. A good agreement was obtained between experimental results and numerical predictions.

The present work aims to analyze the strength and failure modes for the multi holes pin joint configurations made from unidirectional glass/epoxy nanoclay laminates. The geometric parameters, i.e. the distance from the free edge of the specimen to the diameter of the first two holes (E/D) ratio, the distance between two holes along the length of the specimen to the diameter of the hole (F/D) ratio, the distance between the two holes along the width of the specimen to the diameter of the hole (P/D) ratio and side width to diameter (S/D) ratio were studied for their effect on strength and failure modes of the joint. Design of experiment with Taguchi method was used for the optimization of different geometric parameters. Analysis of variance was applied to determine the influence of individual geometric parameter on the strength of the joint. The results demonstrate that the E/D and F/D ratios are the most significant parameters to increase the strength of multi holes pin joint configurations. Their percentage contributions were about 62% to 65% and 23% to 26%, respectively. Thereafter, the characteristic curve method along with Tsai–Wu failure criteria was applied to compare the numerical and experimental predictions.

Injection molding is one of the most important processes in manufacturing nowadays. Thus, attention must be give towards the optimization of the product defects. Parameters have been chosen by screening tests to improve the process quality. The main purpose of this study is to optimize the processing condition using Taguchi Method on shrinkage for HDPE-Clay specimen. The experiment starts by preparing the mixture between HDPE and clay. Then, screening test is conducted to obtain the parameters. The parameters are melt temperature, injection speed, injection pressure and cooling time. By using the array orthogonal L9 (34), signal to noise ratio and ANOVA were conducted. Based on the S / N ratio analysis, best combination can be produced for warpage (melt temperature: 190°C, injection speed: 40%, injection pressure: 30% and cooling time: 3 seconds). While for ANOVA, melt temperature is most significant with 60.28% for warpage.

This paper presents the use of the Taguchi method, Computational-Fluid-Dynamics and electromagnetic field analysis to optimize the design of a micro wind turbine for a dental fiber handpiece. An orthogonal array, the signal-to-noise ratio and analysis of variance were used to study the multiple-objectives in the micro wind turbine design. The results showed that: (1) the wire slot fill factor and stator angle have a significant influence on the flow rate, whereas wire slot fill factor and inlet dimensions have a significant effect on the pressure drop; (2) the micro wind turbine reduces electricity usage by 25 watts in a day and produces brightness of 20,000-23,000 lux. The proposed design of the micro wind turbine not only saves energy but also reduces the need for replacement halogen lamp.

Polyester fibre is the synthetic fiber made with man-made fibers. Its surface is smooth with the texture of fine linen. It has good flexibility and durability and is the best non-iron fibres. In order to promote the accuracy and reduce the quality deviation of melt spinning, the Taguchi method was adopted in the melt spinning process. The aim of the research is to enhance the optimization of the melt spinning process using the material polyester. First, the Taguchi method is applied to establish the design of experiment. An analysis of variance will be done to arrive at the significant factors that influence the melt spinning quality the most. Lastly, confirmation experiments verified the reproducibility of this experiment. Confirmed by the experiments, results showed that the obtained SN ratios were greater than the signal-to-noise ratio of nine orthogonal array experiments and this means the experiment is reliable.

We report an octave-spanning coherent supercontinuum (SC) fiber laser with excellentnoise and polarization properties. This was achieved by pumping a highly birefringent all-normaldispersion (ANDi) photonic crystal fiber with a compact high-power ytterbium femtosecond laserat 1049 nm. This system generates an ultra-flat SC spectrum from 670 nm to 1390 nm with apower spectral density higher than 0.4 mW/nm and a polarization extinction ratio of 17 dB acrossthe entire bandwidth. An average pulse-to-pulse relative intensity noise (RIN) down to 0.54%from 700 nm to 1100 nm has been measured and found to be in good agreement with numericalsimulations. This highly-stable broadband source could find strong potential applications inbiomedical imaging and spectroscopy where improved signal to noise ratio is essential.
