Variance analysis

In the present study, the heritability for days to 50% flowering, days to maturity, plant height at maturity, total number of pods per plant, number-filled pods per plant, 100- seed weight, and grain yield per plant were estimated by variance components from variance analysis of parents and F2 and F2:3 progeny families derived from a single cross.

The objectives of this study were to identify promising rice genotypes and evaluate the genetic variance and effectiveness of selection of the rice varieties for several yield attributing traits. A varietal trial of fifteen rice genotypes was laid out in a randomized complete block design (RCBD) with three replications in a farmer’s field in Sundarbazar, Lamjung, Nepal during the rainy season of 2018.

This work is focused on the influence of different friction stir welding (FSW) parameters on AA6082 T-6 and AA5083-O alloys welding quality, by using Taguchi, Grey Relational and Weight Method. Four welding parameters were investigated, namely tool rotation speed (TRS), welding speed (WS), tool pin profile (TPP) and shoulder diameter (SD).

The experiment was conducted in experimental Farm, Regional Research Station, Anand Agricultural University from July to November 2018toestimate the extent of variability present in rice genotypes with respect to yield and its component traits. The estimates of genotypic and phenotypic variances for the characters like plant height, effective tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant, harvest index and 1000 grain weight, genotypic variance contributed larger in phenotypic variance.

This paper develops an original framework that mathematically expresses the coupling of the weight window and source biasing techniques, allowing the authors to explore the impact of inconsistent source sampling on the variance of MC results. A numerical experiment supports this new framework and suggests that certain classes of problems may be relatively insensitive to inconsistent source sampling schemes with moderate levels of splitting and rouletting.

(BQ) The paper describes the application of the fuzzy logic analysis coupled with Taguchi methods to optimise the precision and accuracy of the high-speed electrical discharge machining (EDM) process. A fuzzy logic system is used to investigate relationships between the machining precision and accuracy for determining the efficiency of each parameter design of the Taguchi dynamic experiments.
