Experimental Investigation on Electrical Discharge Drilling of Ti-6Al-4V Alloy

Abstract: This article describes the experimental investigation related to creation of holes in aerospace titanium alloy workpiece using static electrode machining and electrical discharge drilling (EDD) process. Special attachment for holding and rotating the tool electrode was developed and installed on electrical discharge machining (EDM) machine by replacing the original conventional tool holder provided on die sinking EDM. The effect of input parameters such as gap current, pulse on-time, duty factor and RPM of tool electrode on output parameters for average hole circularity (Ca) and average surface roughness (Ra) have been studied. It is observed that the effect of rotating electrode machining has considerable influence on the output parameters over stationary electrode machining. The micro-graphs and photographs of few selected samples were taken by SEM and metallurgical microscope, which also commensurate with the findings of the study.

Supply Chain Innovation is a Key to Superior Firm Performance an Insight from Indian Cement Manufacturing

Abstract: The following statistical study shows the results of an investigation of supply chain innovation practices of Indian Cement Manufacturers, which are a significantly large and quickly advancing industry in India. Aside from being a study of adoption of supply chain innovation practices (SCIP) in an emerging super power (India) the benefits of supply chain innovation (SCI) are discussed including the major advances in supply chain management. The statistical study compared innovation supply chain practices (like JIT, WMS, CPFR, and others) in 125 large cement firms to their financial performance measures (ROI, market share, EBIDTA, customer satisfaction, productivity). The resulting correlations showed very high levels of reliability and adequacy, and were uses to make conclusions on which supply chain innovation practices had a positive impact on company financial performance. The conclusions are somewhat astounding with the interesting finding that some innovation practices do not support firm performance and maybe should be avoided; while others ICS practices are shown to support firm performance to a high degree.

Influence of Dielectric Coating on Performance of Surface Plasmon Resonance Sensor

Abstract: In the present study, the nature of dielectric layer above metal layer in surface plasmon resonance sensor is investigated. The performance-defining parameters, i.e., shift in resonance angle, half width at half maximum, and minimum reflection intensity, are investigated according to the variation of refractive index (real as well as imaginary) of dielectric layer. Moreover, these parameters are investigated according to the thickness variation of the dielectric layer at different purely real as well as complex refractive index of the dielectric layer.

Hydrogen bonding in different pyrimidine–methanol clusters probed by polarized Raman spectroscopy and DFT calculations

Abstract: We report on the hydrogen bonding between pyrimidine (Pd) and methanol (M) as H-donor in this study. Hydrogen bonds between pyrimidine and methanol molecules as well as those between different methanol molecules significantly influence the spectral features at high dilution. The ring-breathing mode ν1 of the reference system Pd was chosen as a marker band to probe the degree of hydrogen bonding. Polarized Raman spectra in the region 970–1020 cm−1 for binary mixtures of (pyrimidine + methanol) at 28 different mole fractions were recorded. A Raman line shape analysis of the isotropic Raman line profiles at all concentrations revealed three distinct spectral components at mole fractions of Pd below 0.75. The three components are attributed to three distinct groups of species: ‘free Pd’ (pd), ‘Pd with low methanol content’ (pd1) and ‘Pd with high-methanol content’ (pd2). The two latter species differ considerably in the pattern and the strengths of the hydrogen bonds. The results of density functional theory calculations on structures and vibrational spectra of neat Pd and eight Pd/M complexes with varying methanol content support our interpretations of the experimental results. A nice spectra–structure correlation for the different cluster subgroups was obtained, similar to earlier results obtained for Pd and water. Apart from N···H and O···H hydrogen bonds between pyrimidine and methanol, O···H hydrogen bonds formed among the methanol molecules in the cluster at high methanol content also play a crucial role in the interpretation of the experimental results.
