“…Regardless of the category of the quality characteristic, a higher ratio corresponds to a higher quality characteristic. Therefore, the optimal level of the process parameters corresponds to the one with the highest ratio [ 39 ]. Optimizing the biosensor through the design of experiments helps guide efforts to improve the performance of future sensing devices.…”

Microfluidic biosensors have played an important and challenging role for the rapid detection of the new severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Previous studies have shown that the kinetic binding reaction of the target antigen is strongly affected by process parameters. The purpose of this research was to optimize the performance of a microfluidic biosensor using two different approaches: Taguchi optimization and artificial neural network (ANN) optimization. Taguchi L8(2 5 ) orthogonal array involving eight groups of experiments for five key parameters, which are microchannel shape, biosensor position, applied alternating current voltage, adsorption constant, and average inlet flow velocity, at two levels each, are performed to minimize the detection time of a biosensor excited by an alternating current electrothermal force. Signal to noise ratio ( ) and analysis of variance were used to reach the optimal levels of process parameters and to demonstrate their percentage contributions, in terms of improved device response time. The principal results of this study showed that the Taguchi method was able to identify that the kinetic adsorption rate is the most influential parameter at 93% contribution, and the reaction surface position is the least influential parameter at 0.07% contribution. Also, the ANN model was able to accurately predict the optimal input values with a very low prediction error. Overall, the major conclusion of this study is both the Taguchi and ANN approaches can be effectively utilized to optimize the performance of a microfluidic biosensor. These advances have the potential to revolutionize the field of biosensing.

The addition of transition element oxides to tungsten heavy alloys (WHAs) fabricated by powder metallurgy technique provides new materials with higher density and electrical conductivity, which may be adequate in some applications such as kinetic energy penetrators. Additionally, materials with higher electrical conductivity are required for electrical contact applications such as electrical discharge machining (EDM) electrode materials. WHAs were fabricated by compacting its mixed constituents followed by sintering. Ni, Co and Fe are used as binding phases of the tungsten particles and oxides of Zr, Ti and Y are used as oxide dispersing strengthening (ODS) agents of the sintered materials. The results show that all of the chosen factors (i.e., pressure of compaction process, temperature of sintering, type of binding material and type of oxide) have clear effects on all properties of ODS tungsten heavy alloy specimens. The density and electrical conductivity increase with the increase in sintering temperature. Hardness and compression strength were also measured to evaluate the mechanical properties of sintered samples.

increased nutrient levels and algal blooms can also cause drinking water problems in communities near dead zones and upstream. humans, fish, marine mammals, birds, and other animals are all adversely affected by the toxins produced by toxic algal blooms. The purpose of this study is The effect of The combined system of Hydrodynamic Cavitation, Ozone (O3), and Hydrogen Peroxide (H2O2) on the removal of Chlorophyll a and Organic substances in the raw water entering the Sanandaj treatment plant. In this study, we examined the following variables: pH, Retention Time, Pressure, Distance, Ozone dose, and Hydrogen Peroxide dose. Utilizing Taguchi design methodology, experiments were planned and optimized. Chlorophyll a and Total Organic Carbon (TOC) can be removed most effectively under the following conditions: 5 bar of cavitation pressure, 90 min of retention time, a pH of 5, 1 m3/h of Flow, a distance of 25 cm from the orifice, 3 gr/h of ozone, and 2 gr/l of Hydrogen Peroxide. The most efficient factor in the degradation of TOC and Chlorophyll a was determined to be cavitation pressure based on the percentage contributions of each factor (38.64 percent and 35.05 percent, respectively). H2O2 was found to have the most negligible impact on degradation efficiency (4.24 percent and 4.11 percent, respectively).
