Abstract

In the global scenario, the Business Process Outsourcing (BPO) sector is one of the fast growing sectors after the liberalisation, privatisation, and globalisation, to increase job opportunities day by day. The present study examines the relationship between the workplace stress, well-being, and quality of life. It also aims to investigate the differences between day and night shift workers, males and females, and married and unmarried employees working in BPO sector with respect to experienced workplace stress, well-being and quality of life. In the present study, 120 employees were selected from the different business process companies. The analysis revealed that organisational role stress is significantly correlated with sociability. And, quality of work life was significantly correlated with well-being. However, the difference in gender was found on organisational role stress and some of its dimensions, as well as on quality of work life. Succinctly, married and unmarried employees differed on dimensions of well-being. As far as, shift timings are concerned, day shift employees were found to differ significantly from night shift employees on organisational role stress and its few dimensions, as well as on quality of work life. From the findings of the study, it has been understood that the gender differences, marital status difference, and difference in shift timings have made an impact on the variables such as workplace stress, quality of work life, and wellbeing of BPO employees.

Abstract

The study presents assessment and potential oceanographic applications of sea-surface temperature (SST), ocean net shortwave radiation (SWR) and chlorophyll concentration (CC) observations obtained from various geostationary platforms. SST and SWR from imager on-board Indian National Satellite (INSAT- 3D) and CC from Global Ocean Color Imager (GOCI) on-board communication ocean and meteorological satellite (COMS) have been used in the analysis. Relative advantages of high temporal resolution obtained from the geostationary platform compared to polar orbiting platforms are demonstrated. Comparison of INSAT-3D SST with observations gives a correlation of 0.85 and RMSE of 0.81 K. These platforms definitely provide a highly reliable source of continuous observations, which is useful in monitoring dynamic oceanic features such as thermal fronts, chlorophyll blooms, air–sea exchange fluxes, etc. on diurnal to daily timescales.

Abstract

For any retail company, managing inventory is of prime importance. Every store should have enough items so that it can fulfill the demand. To achieve this, the stores must be restocked before those items become out of stock. For restocking, the items must arrive from a fulfillment center which distributes the items to various stores, also called distribution centers. Since, distribution center and fulfillment centers are generally far from each other, there is a delay between request for restock and the time it takes for the item to reach from fulfillment centers to distribution centers. To prevent out of stock conditions, the request should be made by considering the time it takes for an item to arrive from fulfillment center. The quantity of item also determines the request time as only few quantities of large items can be sent at once and need multiple transits to restock to the required numbers. Along with these, there are other conditions like general traffic, seasonal climate variations, etc. that can affect the transit time of items. All of these conditions must be taken care while deciding when the item is requested. The proposed system decides the request time and quantity of items along with different variations by training from years of data. This allows the system to work more efficiently and prevent the out of stock conditions to increase sales of the company.

Abstract

Electroless deposition techniques can be utilized in manufacturing coatings with self-lubricating properties suitable for industrial applications. Electroless Ni-B coatings have emerged as a better alternative to electrodeposited Ni-based coatings and apart from possessing high hardness; these alloy coatings are well-known for their superior resistance to wear and abrasion. Incorporation of hBN as solid lubricating phase in electroless Ni-B alloy matrices can effectively improve its tribological characteristics. This study presents microstructural, mechanical and tribological characterizations of electroless Ni-B and Ni-B/hBN composite coatings developed on steel substrates. Microstructural features and phase compositions of the deposited coatings can be systematically studied involving FESEM and XRD analyses. Studies of deposited coatings with X-ray diffraction reveal a mixed phase amorphous/ crystalline characteristic and confirms the existence of hBN in coatings’ matrix. Heat treatment of deposited samples (at 450o C, 1hr) is performed to observe changes in structural aspects of coatings. Thorough tribological characterizations on all deposited Ni-B based coatings performed in sliding and scratch modes reveal significant improvements in frictional behaviour with the addition of hBN. Notably, annealing imparts significant changes in electroless Ni-B coatings’ structure as new diffraction peaks corresponding to crystalline nickel (Ni) and nickel boride intermetallic phases (Ni3B, and Ni2B) are noticed. Formation of these hard intermetallic phases upon heat treatment corroborates to the betterment in mechanical and tribological characteristics of deposited coatings.
