Abstract

Purpose

In this study the comparison is presented for the variation in cross-sectional shape along the height of the building model. For this purpose Model B and Model C are having the considerable variation and Model A result can be easily predicted on the basis of the result of Model B and C while Model X is considered for the validation purposes only and it is well established that the results are within the allowable limit. This paper aims to discuss these wind generated effects in the tall building model.

Design/methodology/approach

Computational Fluid Dynamics (CFD) in ANSYS: CFX is used to investigate the wind effects on varying cross-sectional shape along the height of the building model.

Findings

From pressure contours, it was observed that shape and size of the face is independent of the pressure distribution. It is also observed that pressure distribution for the windward face (A) was less than the magnitude of the leeward face for both models. The leeward face and lateral faces had similar pressure distribution. Also slight changes in pressure distribution were observed at the periphery of the models.

Originality/value

This study has been performed to analyse and compare the wind effect on tall buildings having varying cross sections with variation of different cross sections along the height. Most of the studies done in the field of tall buildings are concentrated to one particular cross-sectional shape while the present study investigates wind effects for combination of two types of cross sections along the height. This analysis is performed for wind incidence angles ranging from 0° to 90° at an interval of 30°. Analysis of wind flow characteristics of two models, Models B and C will be computed using CFD. These two models are the variation of Model A which is a combination of two types of cross section that is square and plus. Square and plus cross-sectional heights for Model B are 48 m and 144 m, respectively. Similarly, square and plus cross-sectional heights for Model C are 144 m and 48 m, respectively. The results are interpreted using pressure contours and streamlines, and comparative graphs of drag and lift forces are presented.

Abstract

Purpose

The COVID-19 pandemic is spreading in India and different parts of the world. The outbreak delivered not only the condition of dying from infection but also forced people (especially office workers and students) to perform all working (office work, classes, assignments, etc.) and non-working activities (leisure activities such as social media, gaming, etc.) at home using handheld devices (HHDs). In this situation, HHD usage for longer durations is mainly responsible for work-related health issues. Therefore, the paper aims to explore HHD usage patterns and musculoskeletal disorders (MSDs) amongst HHD users during homestay and the impact of individual and HHD usage–related factors on MSDs.

Design/methodology/approach

From different states of India, 651 people (especially HHD users from universities and industries) were sampled by using systematic cluster random sampling. In addition, an online questionnaire was used to collect data on the prevalence and risk factors of MSDs. Finally, mean comparisons and chi-square analysis was used to analyse the collected data.

Findings

The prevalence rate of MSDs was higher in upper body parts as compared to the lower body parts. The association of gender with MSDs in various body parts was substantial. The time spent on various working and non-working activities using HHDs was significantly associated with MSDs in upper body parts.

Practical implications

Homestay work may be used as an alternative working arrangement, and the risk factors that have the most significant impact on the health of HHD users may be identified by organizations. The findings suggest the proper use of HHDs as per their essential need with intermediate recreational activities.

Originality/value

It is observed that the musculoskeletal health of office workers and university students is a cause for concern during homestay. The current study provides the prevalence of MSDs experienced by HHD users and the association of individual and HHD usage factors with MSDs.

The recent global pandemic of COVID-19 has impacted this sector to a great extent. This research study targets the MSME industry and points out the directly linked enablers adding to improve the sector's resiliency and sustainability. Therefore, identification and the interrelationship between the MSME enablers need to be studied, which helps make a preliminary list that deals with their impedance benefaction towards resiliency increment.

Design/methodology/approach

The writers have done a comprehensive literature analysis of the enablers for the MSME sector to enable effectively and efficiently during emergencies and pandemics. An endeavor has been made on the enablers to order them by utilizing the modified Total Interpretative Structure Modelling (m-TISM) technique. Authentication of this research work highlights the significance of enablers and their position in a hierarchical structure. Further, MICMAC investigation on the recognized enablers is performed to arrange them in the four quadrants on their dependence and driving power.

Findings

The authors have attempted to predict the significance of the MSME sector and its essential contribution to the development of India's economy. The result of m-TISM in the current research work revealed the essential commitment of a hierarchical design dealing with the MSME considering the viewpoint of future development. The well-planned traditional design in the MSME helps establish better government policies and programs and transport infrastructure.

Research limitations/implications

Every research study has a few restrictions. Likewise, the boundaries of the current study are that inputs collated for fostering the models are from a few specialists that may not mirror the assessment of the whole MSME sector.

Practical implications

The MSME sector is the developing sector in the current day, and it is needed to keep supporting the sector for the country's development. The current study has set out the functional establishment to improve MSME practicality. In addition, the research highlights the accountability of the MSME authorities to go with the identified enablers having solid driving power for successful usage of the available resources. This will help the MSME development and add value to practitioners and policymakers in the future.

Originality/value

The growth of this sector is essential for the development of the economy and the development of a nation. The current study presents a unique structure that gives a superior comprehension of the enablers. It will help play a crucial role in developing the MSME area. The structure model developed with the assistance of m-TISM and MICMAC examine the identified enablers with inputs from experts in the field. The hierarchy developed from the study recognized the enablers located on their commitment of suitability development of the MSME field.

Abstract

Purpose

India liberalized its economy in 1991, which resulted in intense global competition, quality-conscious and demanding customers. Additionally, significant technological advancements lead to enhancements in products and processes. These forced Indian organizations to adopt innovative business strategies in the past 30 years. Meanwhile, the Lean Six Sigma methodology has significantly grown with vast applicability during the past 30 years. Thus, the purpose of this study is to develop the learning on Lean Six Sigma methodology in the Indian context through investigation of literature.

Design/methodology/approach

A three-stage systematic literature review approach was adopted to investigate the literature during the present study. In total, 187 articles published in 62 journals/conference proceedings from 2005 to 2022 (18 years) were shortlisted. The first part of the article summarizes the significant milestones towards the quality journey in the Indian context, along with the evolution of the Lean Six Sigma methodology. The second part examines the shortlisted papers on Lean Six Sigma frameworks, their applicability in industrial sectors, performance metrics, outcomes realized, publication trends, authorship patterns and leading researchers from the Indian perspective.

Findings

Lean Six Sigma has emerged as a highly acclaimed and structured business improvement strategy worldwide. The Indian economy has seen remarkable growth in the past decade and is one of the fastest-growing economies in the 21st century. Lean Six Sigma implementation in India has significantly increased from 2014 onward. The study revealed that researchers have proposed several different frameworks for Lean Six Sigma implementation, the majority of which are conceptual. Furthermore, the balanced applicability of Lean Six Sigma in manufacturing and service sectors was observed with the highest implementation in the health-care sector. Additionally, the widely adopted tools, techniques along with performance metrics exploring case studies were reported along with a summary of eminent and leading researchers in the Indian context.

Abstract

Purpose

The purpose of this study is to analyze direct current (DC) drive stability, including parameter uncertainty and perturbation in the feedback loop, by computing disk margins.

Design/methodology/approach

Although the closed-loop stability analysis of a DC drive has been presented well in the referenced papers, the effect of parameter uncertainty and perturbation in the feedback loop has not yet been discussed well. In this study, the conventional and disk-based stability margins were measured and compared for the nominal parameters of the DC drive. Subsequently, the smallest disk-based margins that destabilize the feedback loop for a given perturbation are computed and compared with normal disk margins.

Findings

The disk-based margin offered by the DC drive controlled by the JAYA-PID controller is disk gain margins (DGM) = 8.41 dB and disk phase margin (DPM) = 48.410 and the smallest disk-based margin offered is DGM = 1.51 dB and DPM = 9.950. In addition, the effect of the modeled uncertainty on the disk stability margins was analyzed, and it was observed that the maximum allowable parameter uncertainty with the JAYA controller was 73% of its nominal parameters. The simulation results were validated using an experimental testbed.

The primary focus of the case is how an internet-based business model in the food industry took shape.

Study level/applicability

The case enumerates how strategic analysis can be performed to analyze the firm based on topics such as the analysis of the mission and vision of Holachef based on the Ashridge mission model, examining strategy with Mintzberg’s 5Ps of strategy, performing a PESTLE analysis of HolaChef, evaluating Holachef with Porter’s industry analysis, performing Value net analysis for Holachef, examining Holachef’s business with strategy group analysis, examining the roots of core competencies of Holachef and explaining Holachef’s resource and capabilities with the valuable, rare, inimitable, non-substitutable (VRIN) Framework.

Case overview

Saurabh Saxena and Anil Gelra co-founded Holachef, “a restaurant in cloud” in March 2014. In a city like Mumbai, there are many households where both partners work; this had led to difficulties for people finding time to prepare food at home. Holachef is an online delivery platform which aggregates chefs for home-like multiple cuisine preparation. Holachef’s vision is to satisfy the need for homemade healthy food. The three pillars of Holachef to provide such food are technology (orders are taken through a website, mobile application and phone calls), food (enlisted chefs on the website) and logistics. The food prepared by chefs is assembled at different distribution centres and routed to customers. The efficient logistics and storage system maintain the quality of food. These pillars help Holachef to serve customers with efficiency at affordable prices.

Expected learning outcomes

Performing strategic analysis from both an industrial organization theory and resource-based view (RBV) perspective with VRIN framework. This is in the context of online business models in a digitizing India. Entrepreneurial strategy concepts and challenges faced by entrepreneurs in an online business.
