Mechanical and Micro-structural Properties of Friction Stir Welded Dissimilar Joints of Aluminium Alloys
Abstract: Abstract In this work, the microstructure and mechanical properties of friction stir welded dissimilar joints of 6101-to-6063 aluminium alloys were evaluated. Tool with round pin profile was fabricated of high speed steel material which was suitable for friction stir welding of aluminium alloys. Under monotonic tensile loading, an increase in the joint strength was observed with the increase in the tool rotational speed. The micro-hardness of friction stir zone increased …

Fractional Riemannian Fuzzy C-Means with Time-Series Regularization for Economic Manifold Forecasting
Abstract: A fractional Riemannian fuzzy c-means framework is proposed for uncertain economic forecasting on non-Euclidean data domains. Observations are represented on a Riemannian manifold, cluster centres are intrinsic prototypes, and a latent fuzzy regime signal is regularised by both autoregressive and fractional-memory penalties. The resulting objective couples geometric clustering with time-series consistency, thereby discouraging partitions that are locally plausible but temporally incoherent. Closed-form membership updates, exponential-map centre updates, normal equations for …

An Aggregate-Breakage Percolation Model and ANN-Based Internal Validation for Curvature-Dependent Electrical Conductivity of MWCNT/TPU Nanocomposites
Abstract: Strain-dependent percolation models are mostly built and tested for uniaxial tension, yet many flexible sensors and stretchable devices work mainly in bending, where the outer fibre is stretched, the inner fibre is compressed and the strain changes with thickness. This study extends an aggregate-breakage percolation model, originally formulated for uniaxial strain, to through-thickness bending of a multi-walled carbon nanotube/thermoplastic polyurethane (MWCNT/TPU) nanocomposite. The local strain is taken as ε(y) = …

Research Frame work of Missing Data Analysis using Mathematical Models
Abstract: AbstractThis article deals with providing an overall framework of missing data analysis using mathematical models. Mathematical models serves at large for missing data imputation. Several algorithms in machine learning techniques like Mean, Median, Standard Deviation, Regression and Naïve Bayesian classifier use Mathematical models for analysis. The performance of above mathematical models has been compared by using correlation statistics analysis gives the imputed values are positively related or negatively related or …

Performance Evaluation of an Arbitrary Profiled Vertical Fin in Non-Newtonian Medium
Abstract: Abstract In this article, the problem of a parabolic profiled fin dissipating heat by natural convection to quiescent non-Newtonian fluid has been solved theoretically. The generalized equations of temperature distribution and heat transfer rates have been generated using the appropriate boundary conditions with different flow behavior index (n). The results obtained from the graphs indicated that there is a significant influence of flow behavior index (n) and fin parameter (M) …

Reduction of Hydrogen Embrittlement of HSLA Steel by Ion Implantation Surface Modification Technique
Abstract: There are many techniques available for the surface modification of the substrate. One of the important ion implantation techniques is plasma source ion implantation (PSII). Ion implantation is a vacuum process in which a beam of ions is directed to the surface and introduced into it. This technique produces minimum invasion of the bulk properties of the substrate. Nitrogen plasma ion implantation treatments were done on the substrate, Cu-strengthened HSLA …

The Dangerous Effect of Delirium in Intensive Care Unit: Implication for Nurses
Abstract: Intensive care unit (ICU) syndrome and ICU psychosis have been used to mean a cluster of psychiatric symptoms that are common to the ICU environment. It is often posited that the ICU environment causes a lot of sleep deprivation and sensory overload or monotony, which result to this syndrome. However the study has shown that ICU syndrome does not differ from delirium and that it is caused exclusively by organic …

Elasticity of Substitution—A Summary
Abstract: This paper has a very specific purpose of explaining the differences among Allen elasticity of substitution, Morishima elasticity of substitution and McFadden elasticity of substitution. It is roughly divided into three sections. The first section traces the evolutionary trajectory and provides a summarized description(including formula) of these three measurements. The next section discusses a hypothetical scenario to bring out the intuition behind elasticity of substitution more vividly. In the last …

Feasibility of Optimized Heat Source Assisted Combustion in Solid Rocket Motors
Abstract: Advances in rocket propulsion have a predominant role in space exploration developments. As an active chemical propulsion system, the efficiency of operations depends largely upon the nature of the combustion process and related energy transfer. Modern rockets are well known to epitomizes a distinct area of propulsion assisted by external thermal source(s)/rocket boosters. The presence of external heat source(s) encourages high possibility of fire risk/ hazards, which can adequately threaten …
