“…The orthogonal method is commonly used to optimize industrial processes (i.e., automobile or electronics) because it requires a minimal amount of experimentation (Kondapalli et al, 2013). For example, an experiment of four-factors with three levels each will require the execution of nine treatments, but a factorial design will require the execution of 81 treatments.…”

Four local parasitoids of spotted wing drosophila, Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), were collected in Mexico in 2013–2015. To increase insectary production of the fly for mass rearing of its parasitoids, a wheat germ diet that uses low‐cost ingredients was optimized through the orthogonal array L9 (34, i.e., four controllable factors with three levels each) (Taguchi method). The resulting optimized diet consisted of 12 ml ethyl alcohol, 36 g maize flour, 45 g table sugar, and 42 g brewer's yeast. Confirmation tests indicated that this diet produced 33.9, 87.0, and 78.6% more larvae, pupae, and adults, respectively, than the old version (non‐optimized wheat germ recipe) but there were no statistical differences in sex ratio, hind tibia length of females, and developmental time from egg to adult. Additionally, the optimized diet had a similar performance in most of the evaluated parameters (same as in the confirmation tests) compared to banana, the current host of the D. suzukii colony. These results indicate that an improved wheat germ diet is available to rear this fly, which will facilitate the rearing of its local parasitoids.

Girth welded replica of API X70M material have been produced on NG-GMAW welding technique. The particular area of interest is to develop suitable girth welding process parameter using NGGMAW. The major aim of the work was to replicate welds having tensile strength between 650 and 680 MPa. Design of Experiment (DoE) method by Taguchi design, using some selected welding processes was adopted. Two process parameters (factors) – arc voltage and wire feed rate, (the variables), and three levels were used. The resultant joint property on tensile strength of X70M pipeline was examined. The targeted mechanical property was achieved by selecting the best process parameters. Their effects on ultimate tensile strength – UTS was analysed using statistical technique – analysis of variance - ANOVA and Signal to Noise - S/N ratio with ‘thebigger-the–better’ value. Validation was done using MIDAS NFX (an FEA) mechanical engineering software. In conclusion, process parameters that affects or influences the girth welded properties of API X70M under field conditions were identified. Guidance for the specifications and selection of processes that could be used in field-welding for optimum performance has been recommended. Keywords: Optimization, Girth-Weld, Process Parameters, Tensile Strength, NG-GMAW

“…The trial data were developed in a pattern of L9 Orthogonal Array (OA) So possible output can be predicted based on the input parameters of the experimentation. Results can be analysed by using analysis techniques such as ANOVA and linear regression [12]. Experimental results are shown by plotting response surface methodology (RSM) graph.…”

The aim of this work is to evaluate the failure analysis of jute fabric reinforced composite using statistical technique for marine applications. A fracture mechanics approach is proposed to determine the failure load and fracture toughness of the composite. Jute fiber reinforced epoxy composites were fabricated by hand lay-up technique. The polymer composite is intended for marine applications as an alternative material, mainly in high moisture environments. Thus an investigation was conducted to evaluate the fracture mechanic parameter by immersing composite specimens in sea water. The statistical method of Taguchi was used for experimental design. Edge Notched Tension (ENT) and Single Edge Notched Bend (SENB) test were conducted according to the ASTM E1922 and ASTM D5045 respectively. Main effect graphs are obtained to study the effect of a/w (Crack length to width ratio), thickness and immersion time of composite on fracture mechanics parameters. The approach of calculating the percentage of contribution of control factors was established using by analysis of variance (ANOVA). The influence of fracture parameters of control factors can be analysed by using 3-D response surface graph (RSM). The Validation of experimental results for fracture parameters agreed well with the predicted values.
