The purpose of the present work is identification and prioritization of barriers to Lean Six Sigma (LSS) implementation in Indian manufacturing industries in the context of Industry 4.0 (I4.0) to surmount the impediments in the path of successful implementation.

In total, 27 barriers identified through critical review of literature and expert's opinion are evaluated with Cronbach's alpha values including item-total correlations or corrected item-total correlations (CITC) using statistical tool. Finally, 20 barriers were analyzed and ranked employing Fuzzy Analytical Hierarchy Process (FAHP).

The study depicts that “Lack of leadership, advisory and monitoring,” “Lack of clarity about economic benefits” and “Lack of integration of LSS with smart tools/I4.0” are potential barriers to drive the path for proper implementation of LSS in Industry 4.0 with due consideration of its technologies in Indian manufacturing industries.

The study provides better knowledge platform for academicians and researchers about hidden aspects of LSS implementation barriers in view of advanced manufacturing technologies. This research will help the practitioners to design their business plans in implementing new quality improvement tools to get advantage in current competitive environment.

The barriers are selected based on literature and opinion from industry and academic experts. Five major criteria are decided after incorporating inputs. The ranking of the barriers is attained by well standard mathematical technique. This will enable the practitioners to design strategies to eliminate the hindrances in order to shape the right path for effective implementation of LSS approach in view of advanced manufacturing technologies.

The present research work aims to study the effect of average beam power (laser process parameters) on the overlapping factor, depth of penetration (DOP), weld bead width, fusion zone and heat affected zone (HAZ) in laser welding of 304L and st37 steel. Back side and top surface morphology of the welded joints have also been studied for varying average beam power.

Laser welding of austenitic stainless steel (304L) and carbon steel (st37) was carried out using Nd:YAG laser integrated with ABB IRB 1410 robot in pulse mode. The selection of laser process parameters was based on the specification of available laser welding machine. Dissimilar laser welding of 304L and st37 carbon steel for full depth of penetration have been performed, with varying average beam power (225-510W) and constant welding speed (5mm/s) and pulse width (5ms).

Recrystallized coarse grains were observed adjacent to the fusion zone and nucleated grains were seen away from the fusion zone towards carbon steel. Overlapping factor and HAZ width st37 side increases with increase in average beam power whereas top weld bead width increases first, attains maximum value and then subsequently decreases. Bottom weld bead width increases with increase in average beam power. The mechanical properties namely microhardness and tensile strength of the welded joints have been investigated with varying average beam power.

In the recent development of the automobile, power generation and petrochemical industries the application of dissimilar laser welding of austenitic stainless steel (304L) and carbon steel (st37) are gaining importance. Very limited work have been reported in pulsed Nd:YAG dissimilar laser welding of austenitic stainless steel (304L) and carbon steel (st37) for investigating the effect of laser process parameters on weld bead geometry, microstructural characterization and mechanical properties of the welded joint.

The purpose of this paper is to develop and validate an extended Define-Measure-Analyze-Improve-Control (DMAIC) based framework through a case study of an Indian fasteners manufacturing organization.

The purpose of this paper is to examine the market structure and value chain of pearl millet grain and fodder in India. There is a decline in demand for human consumption, with an increase in demand for non-food uses like cattle and poultry feed, raw material for starch and breweries industry. This paper explores alternative channels, uses and value chains of pearl millet grain and fodder. The paper examines in what ways small farmers can benefit from the evolving alternative uses for pearl millet grain in cattle and poultry feed industry, breweries and starch industry. The paper also analyses the impact of aggregators in increasing the efficiency of the value chain.

The study collected primary data from farmers, traders, commission agents and exporters and importers with innovative marketing channels with aggregators (Self-Help Groups) and without aggregators to analyze the prospects for improvements in marketing channels and value chain.

Given that the production of pearl millet is scattered and thin, there is a lot of scope for market aggregators to increase scale economies to reduce market costs to supply in bulk to food and industrial uses. Although there was some demand for human consumption high-quality grain, most of the future demand will come from cattle and poultry feed industry, breweries and starch industry. To tap these larger potentials, farmers need to aggregate their produce and ensure regular supply in bulk quantity at least to compete the cost with alternative grains like maize and broken rice.

The research is based on the field-level data collection and observations obtained from Western India. This paper provides insights how the value chain of pearl millet is working and what improvements are needed to make value chain more efficient and inclusive. Although the results are applicable to similar neglected crops and area, more caution is needed.

Through the formation of farmer aggregators, farmers can enhance their bargaining power vis-a-vis industry.

Till now, there is no study that explored the pearl millet value chain in detail in India, and the paper tries to fill this literature gap.

To investigate the mechanical properties of geopolymer concrete at elevated temperatures.

The investigation involved studying the influence of partially replacing fly ash with ground granulated blast furnace slag (GGBS) at different proportions (5%, 10%, 15%, 20% and 25%) on the composition of the geopolymer. This approach aimed to examine how the addition of GGBS impacts the properties of the geopolymer material. The chemical NaOH was purchased from the local supplier of Jamshedpur. The alkali solution was prepared with a concentration of 12 M NaOH to produce the concrete. After several trials, the alkaline-to-binder ratio was determined to be 0.43.

The compressive strength values at 28 days for specimens FG1, FG2, FG3, FG4 and FG5 are 35.42 MPa, 41.26 MPa, 44.79 MPa, 50.51 MPa and 46.33 MPa, respectively. The flexural strength values at 28 days for specimens FG1, FG2, FG3, FG4 and FG5 are 5.31 MPa, 5.64 MPa, 6.12 MPa, 7.15 MPa and 6.48 MPa, respectively. The split tensile strength values at 28 days for specimens FG1, FG2, FG3, FG4 and FG5 are 2.82 MPa, 2.95 MPa, 3.14 MPa, 3.52 MPa and 3.31 MPa, respectively.

This approach allows for the examination of how the addition of GGBS affects the properties of the geopolymer material. Four different temperature levels were chosen for analysis: 100 °C, 300 °C, 500 °C and 700 °C. By subjecting the geopolymer samples to these elevated temperatures, the study aimed to observe any changes in their mechanical.

Shareholder activism is gaining popularity across the globe especially in today’s context where the option of giving up and selling shares to exit the company has become obsolete. Hence, the purpose of this research paper is two-fold, firstly, to investigate the extent to which the minority shareholders of companies listed on the Stock Exchange of Mauritius adopt and make use of the various tools of activism; and secondly, to compare the UK laws on shareholder activism with that of Mauritius.

To achieve these objectives, this study adopted the qualitative research method. Primary data was collected by conducting a survey on minority shareholders of Mauritian listed companies to figure out the extent to which they resort to activism tools, while secondary data was collected through a qualitative legal, document and content analysis to scrutinise regulatory provisions and existing literature on the researched topic.

The results show a moderate implementation level of shareholder activism by the minority investors in Mauritius although it was noted that minority shareholders are more likely to resort to the internal tools of activism rather than external methods. Further to the comparative study conducted, this research recommends a more active participation of the Mauritian regulatory bodies, amendments to the Mauritius Code of Corporate Governance and Mauritius Companies Act and the establishment of a commission responsible for overseeing the exercise of shareholders’ powers and promoting derivative lawsuits among minority shareholders.

Few researchers like Beebeejaun and Koobloll (2018) analysed shareholder activism through the lens of corporate governance with the view of providing recommendations to bring amendments in the Mauritian corporate law landscape. However, to the best of the authors’ knowledge, no research has yet been effectuated on the extent to which shareholder activism is practised by the minority investors in developing countries, for which this existing study aims at filling in the research gap.

The suggested antenna has a switched mechanism among the successive elements of the radiating patch. The purpose of this paper is to develop high gain and less interference at higher frequencies.

The design geometry of the suggested high gain switched beam Yagi-Uda antennas. The constructed antenna has been developed with Rogers Substrate, relative permittivity (ε_r) of 4.4, tangent of loss 0.0009 and with height of 1.6 mm. The proposed antenna has an input impedance of 50, and it is connected to input feed line with 2 mm.

In forthcoming life, the antennas play key role in all the wireless devices, because these devices perform with high gain and high efficacy.

The pivotal principle of this paper is to accomplish the gain as high, high directivity and interference is low at higher frequencies. Therefore, it is more applicable to 5G mobile communications and millimeter wave communications.
