The present work has undertaken a meticulous glance on optimizing the performance of an SGMD configuration utilized a porous poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-co-HFP) membrane. This was carried out by conducting a systematic framework for investigating and optimizing the pertinent parameters such as sweeping gas flow rate, feed temperature, feed concentration and feed flow rate on the permeate flux. For this purpose, the Taguchi method and design of experiment techniques were harnessed to statistically determine optimum operational conditions. Besides that, a comprehensive surface and permeation characterization was conducted against the hand-made membranes. Results showcased that the membrane performance was ultimately controlled by the feed temperature and was nearly (~680) % higher when the temperature raised from 45 to 65 °C. Also, to a lesser extent, the system was dominated by the feed flow rate. As the adopted feed flow rate increases (from 0.2 to 0.6 L/min), around 47.5% increment was bestowed on water permeability characteristics. In contra, 34.5% flux decline was witnessed when higher saline feed concentration (100 g/L) was utilized. In the meantime, with raising the sweeping gas flow rate (from 120 to 300 L/h), the distillate was nearly 129% higher. Based on Taguchi design, the maximum permeate flux (17.3 and 17 kg/m2·h) was secured at 35 g/L, 0.4 L/min, 65 °C and 300 L/h, for both commercial and prepared membranes, respectively.

“…The objective of the experiment is to find the most influencing parameter on the responses. The most important purpose is to set these parameters in such a way that optimal desirable response can be achieved, and the effect of the uncontrollable parameter can be minimized [44]. DOE provides various advantages such as (a) analyses a large amount of data with lesser resources (b) estimates the influence of each parameter on the responses more precisely, and (c) explains the interaction effect of process parameters on responses.…”

Fiber-reinforced composites have established as a high-performance composite of modern advanced structures in various sectors such as automotive, aerospace, and marine industries. Non-conventional machining processes are preferred for the ease of manufacturing operations, which incorporates the machining of high strength and anisotropic material. Non-conventional manufacturing processes produce complicated shaped profiles and better surface characteristics. Abrasive water jet (AWJ) machining is an emerging technology that offers an excellent alternative among the various advanced machining processes due to its process capabilities and excellent machining quality. AWJ machining has fascinated immense attention in the fields of fiber-reinforced composite materials to produce intricate industrial components and attracted the researchers and production industries. It has become well-known in all key areas of researches. Over the past 30 years, lots of research work has been carried out to describe the machining performances among the studied process parameters. This paper reviews the research progresses and integrated functions of AWJ machining in terms of mechanism and machining performances, which includes aspects such as mathematical modeling and optimization. AWJ machining procedure and performance capability are reviewed and depicted in detail. Also, a comprehensive conclusion of this review, along with future perspective, is explored subsequently. The current review work will help future researchers for the proper selection of different FRP material composite compositions and AWJ machining parameters to achieve better performances. The collection of this review literature will also support the production operations in the future.

“…To evaluate the results of the Taguchi experiments, first the signal‐to‐noise (S/N) ratios have to be determined based on the nominal‐the‐best criteria, 40 as shown in Equation ():

normalS / N_{\begin{matrix} i \end{matrix}} = 10 \log ((), \frac{μ_{i}^{2}}{σ_{i}^{2}})

where i is the experiment number 1 to 9: S/N i is the signal‐to‐noise ratio, μ i is the mean isotope ratio (R), and σ i is the standard deviation of the isotope ratio of the i th experiment. The S/N values were further evaluated to determine the mean of S/N per parameter per level.…”

“…Therefore, methods are needed for the simultaneous optimization of various parameters to determine their best combination. In the engineering sciences, the Taguchi design of experiments method is widely applied to optimize the performance of processes or the quality of a product with reduced costs 38–40 . With the orthogonal array of the Taguchi method, multiple parameters and multiple levels are run independently at the same time and evaluated subsequently, thereby reducing the number of experiments needed to aim at a certain target 38,41 …”

Rationale Chloroform, a probable human carcinogen, is commonly detected in various concentration levels in many surface water and groundwater sources. Compound‐specific chlorine stable isotope analysis (Cl‐CSIA) is significant in investigating the fate of chlorinated contaminants in the environment. Analytical conditions should, however, be thoroughly examined for any isotopic fractionation. In this study, we simultaneously optimize three analytical parameters for a robust online Cl‐CSIA of chloroform using the Taguchi design of experiments. Methods For Cl‐CSIA, a purge‐and‐trap autosampler coupled to a gas chromatograph in tandem with a quadrupole mass spectrometer, with electron ionization in selected ion monitoring (SIM) mode, was used. Using the Taguchi method, the dominant parameter affecting the results of Cl‐CSIA for chloroform was identified through concurrent investigation of the signal‐to‐noise ratios (S/N) of three parameters, each at three levels: purging time (5, 10, 15 min), transfer time (80, 120, 160 s), and dwell time (20, 60, 100 ms). Moreover, the optimum combination of the levels was identified. Results The purging time, with a maximum S/N, resulted in the highest influence on the isotope ratios determined. It was further refined through additional experiments to sufficiently extract chloroform from the aqueous phase. Accordingly, 8 min of purging time, 120 s transfer time and 100 ms dwell time were the optimum conditions for Cl‐CSIA of chloroform. Post‐optimization, a precision of ±0.28 ‰ was achieved for 8.4 nmol of chloroform (equivalent to 0.89 μg or approx. 25 nmol Cl‐mass on column). Conclusions A simple online method for Cl‐CSIA of chloroform was optimized with the Taguchi design of experiments. The Taguchi method was very useful for the optimization of the analytical conditions. However, the purging conditions should be fine‐tuned and selected so that sufficient extraction of a target compound is confirmed to acquire a stable and higher precision of the method.
