Nowadays aluminum alloys substitute copper in various applications for weight reduction and cost savings. This paper presents fuzzy-grey Taguchi technique for optimization of friction stir welding condition with seven weld quality attributes of dissimilar A1/Cu joints with the minimum number of experiments for effective productivity and product quality. Taguchi＇s L16 orthogonal array was used to conduct the experiments. Fuzzy inference system was adapted to convert the multi quality characteristics into an equivalent single quality parameter which was opti- mized by Taguchi approach. Four parameters namely, rotational speed of the tool, welding speed, plunging depth and tool pin offset were varied in four levels for investi- gating the effects on the process output like tensile strength, compressive strength, percentage of elongation, bending angle, weld bead thickness and average hardness at the nugget zone. The hardness profile is consistent with the variation of the structure within the nugget zone （NZ）. Confirmation experiment was conducted using predicted optimum parameter setting and it showed that the proposed approach could efficiently optimize weld quality parame- ters. The microstructural analyses were also performed for all the zones of the joints at both Al and Cu sides. It revealed the finer grain size at the NZ compared to the base material due to dynamic recrystallization.

A local convergence analysis of Chebyshev-Halley method having third order of convergence for approximating zero of non-linear operator f(v) = 0 by using convex majorant function and their condition in B-space(Banach space), is presented in this article. We give the error estimate to show the efficiency of our study. Besides, we established the relation between majorant function and Kantorovich or Smale-type result as special cases of our general theory.

AIM To find the association between asthma and different types of functional abdominal pain disorders(FAPDs) among teenagers. METHOD A cross-sectional study was conducted among 13 to 15-year-old children from six randomly selected schools in Anuradhapura district of Sri Lanka. Data were collected using translated and validated selfadministered questionnaires(Rome Ⅲ questionnaire, International Study on Asthma and Allergies in Childhood questionnaire, and Pediatric Quality of Life Inventory 4.0) and administered under an examination setting after obtaining parental consent and *** Of the 1101 children included in the analysis, 157(14.3%) had asthma and 101(9.2%) had at least one FAPDs. Of children with asthma, 19.1% had at least one type of FAPDs. Prevalence rates of functional abdominal pain(FAP)(8.9% vs 3.3% in nonasthmatics), functional dyspepsia(FD)(2.5% vs 0.7%), and abdominal migraine(AM)(3.2% vs 0.4%) were higher in those with asthma(P < 0.05, multiple logistic regression analysis), but not in those with irritable bowel syndrome(4.5% vs 3.1%, P = 0.2). Severe abdominal pain(10.8% vs 4.6%), bloating(16.6% vs 9.6%), nausea(6.4% vs 2.9%), and anorexia(24.2% vs 16.2%) were more prevalent among asthmatics(P < 0.05). Lower gastrointestinal symptoms did not show a significant difference. Scores obtained for health related quality of life(HRQoL) were lower in those with asthma and FAPDs(P < 0.05, unpaired t-test).CONCLUSION Asthma is associated with three different types of FAPDs, namely, FD, AM, and FAP. HRQoL is significantly impaired in teenagers with asthma and FAPDs.
