The reduced ability of eyes to see clearly even with the use of glasses is known as the state of visual impairment. Among the many challenges faced, outdoor travel is one of them requiring to travel through surfaces, which has potholes and bumps.

The depth of the pothole and height of the bump is also conveyed to the user through different vibration pattern of various intensity. With available electronic travel aids, the visually impaired persons are still more inclined to rely on their white cane than carrying additional equipment for obstacle avoidance. In the system, all the components can be attached to the white cane, requiring no additional device to carry.

Upon experimentation with different obstacle types, the system obtained a 24.88% higher score in comparison to normal walking cane. A comparison with the state of the art available systems is also provided.

Moreover, the accuracy of the assistive cane can be heavily degraded if the cane is not properly held by the user. To restrict the user to hold the cane in only required orientation an alignment sensing switch is also proposed, which is missing in the current available literature.

The present study is based on finding the structural response of a tensile membrane structure (TMS) through deformation. The intention of the present research is to develop a basic understanding of reliability analysis and deflection behavior of a pre-tensioned TMS. The mean value first-order second-moment method (MVFOSM) method is used here to evaluate stochastic moments of a performance function with random input variables. Results suggest the influence of modulus of elasticity, the thickness of the membrane, and edge span length are significant for reliability based TMS design.

A simple TMS is designed and simulated by applying external forces (along with prestress), as a manifestation of wind and snow load. A nonlinear analysis is executed to evaluate TMS deflection, followed by calculating the reliability index. Parametric study is done to consider the effect of membrane material, thickness and load location. First-order second moment (FOSM) is used to evaluative the reliability. A comparison of reliability index is done and deflection variations from μ − 3s to μ + 3s are accounted for in this approach.

The effectiveness of deflection is highlighted for the reliability assessment of TMS. Reliability and parametric study collectively examine the proposed geometry and material to facilitate infield design requirements. The estimated β value indicates that most suitable fabric material for a simple TMS should possess an elasticity modulus in the range of 1,000–1,500 MPa, the thickness may be considered to be around 1.00 mm, and additional adjustment of around 5–10 mm is suggested for edge length. The loading position in case of TMS structures can be a sensitive aspect where the rigidity of the surface is dependent on the pre-tensioning of the membrane.

The significance of the parametric study on material and loading for deflection of TMS is emphasized. Due to the lack of consolidated literature in the field combining reliability with deflection limits of a TMS, this work can be very useful for researchers.

The present work outcome may facilitate practitioners in determining effective design methodology and material selection for TMS construction.

The significance of parametric study for serviceability criteria is emphasized. Parameters like pre-stress can be included in future parametric studies to witness in depth behavior of TMS. Due to lack of consolidated literature in the field combining reliability with deflection limits of a TMS, this work can be very useful for the researchers. The present work outcome may facilitate practitioners in determining effective design methodology and material selection for TMS construction.

This paper aims to popularize information retrieval from palm leaf manuscripts among computer scientists to make available the guidance of the age-old heritage in shaping the future.

With computer technology penetrating every aspect of life, information retrieval algorithms can be exploited to help build a system which can dig into the ocean of knowledge from these manuscripts.

The knowledge in them covers all aspects of life. Be it religious beliefs, literature, science, mathematics, or any other. However, due to discontinuation of practice of copying their content on fresh leaves, they now possess a fragile life which needs to be preserved at the earliest. The modern means of digitization can help in their preservation.

The Government of India and other organizations are doing commendable job of preserving and safeguarding country’s heritage and age-old knowledge system through the movement of digitization. In the years to come, the agonizing problem of manuscripts degradation will be eradicated completely. However, next when it will come to mining the knowledge treasure out of these manuscripts, we would be confronted with another helpless situation.

The digitization process would capture the manuscripts from present physical palm leaf to digital image form by clicking high-quality pictures. All the text in a palm leaf will be available in the form of images, but on these images, a simple search for any word would not be possible.

Working towards mining the treasure of knowledge from the palm leaf manuscripts, hordes of challenges have been outlined. Over and above the problem of preventing decay to palm leaf manuscripts is the challenge of deciphering text, image analysis, information retrieval and search. Search is further associated with issues of meaningful and useful extraction through semantic analysis. This paper advocates the dire need for systematic research to be undertaken in this field opening up avenues for past knowledge to guide future prospects in several domains.

Describes how sampling distribution of the estimates of the reliability functions for various failure time distributions is either hard to obtain or is quite complicated and, as such, it becomes difficult to draw inferences about the reliability of a system. To overcome this situation, presents some distribution‐free inference techniques on system reliability and gives Bayesian reliability analysis using conjugate priors.

Women are being victimized sexually everywhere today, whether it is at home or office. Women are targeted for molestation, eve-teasing, and rape and sometimes they are murdered after rape. The objective of the present study is to understand the trend of sexual abuse in the socio-cultural context of India. The study aims to examine the relationship between the victim woman and the perpetrator and the impact of sexual abuse on the well-being of women.

The study applies the content analysis method for collecting data and conducting research. The data for this study were collected from June 2020 to November 2020. The sample cases for the current study were gathered manually by reading each and every news section that was published on sexual abuse in the various newspapers and magazines that were referenced in the introduction.

The study has found that women are mostly targeted for sexual abuse by known persons. The study has also found that girls between 6 and 15 years of age have suffered most from sexual abuse. Moreover, the study has pointed out that sexual abuse has a negative impact on women such as sometimes women commit suicide after sexual abuse, face psychological problems and sometimes they are, and their family members are threatened. Incidents of sexual abuse are affecting the mental happiness of women and an environment of fear is being created for women in society.

This is an original work of the author. The research work is based on content analysis that examines the nature and impact of sexual abuse among women in society by using socio-cultural perspective.

The present study aims to examine the relationship between green economic incentives (GEIs) and environmental commitment (EC) as drivers of the circular economy (CE) practices in small and medium enterprises (SMEs).

A cross-sectional study of 594 assistant managers and SME managers was used while data were analyzed through Smart PLS.

The results showed that GEIs positively affect the SMEs' EC and the CE practice model. Furthermore, EC is the mediator between GEIs and the three CE practices: internal environmental management, eco-design and corporate asset management and recovery (CAM&R).

The present study provided a basis for understanding the relevance of SMEs' CE practices and designing a strategic plan for its implementation. Also, it provides insight into that collaboration between triple helix (the government, SMEs and the community) is needed in increasing environmental awareness toward sustainability.

This study enhanced the natural resource-based view (NRBV), describing the mechanisms that view GEIs and EC as pollution prevention in CE practice.

The aim of this study is to understand the effects of psychological social and financial perceptions of post-retirement life and demographic characteristics on retirement planning behaviour (RPB) of the employees from different occupational sectors.

The primary data from 400 employees in central government, state government and private sector is collected through a structured questionnaire. The questionnaire comprised of 43 items to measure social and financial perceptions and RPB along with demographic information. An exploratory factor analysis (EFA) and multiple linear regression (MLR) analysis are performed to find the significant variables of social and financial perceptions influencing the RPB.

The results of exploratory factor analysis revealed three principle components of social perceptions, four of financial perceptions and three of RPB. The role clarity, involvement, obligations, uncertainty and preparations have significant impact on RPB. This study found a moderate positive correlation between RPB and extracted factors of social and financial perceptions. The study confirms the significant effect of demographic variables such as age, marital status, occupational sector, income and education levels on RPB.

The study has number of implications for government and private sector organisations involved in offering the retirement planning solutions as well as to the employees. The stakeholders may take a note of the role of psychological social (role clarity and social involvement) and financial (financial obligations, uncertainty and preparation for post-retirement life) perceptions that influence RPB. The study also provides an insight to the policy makers for considering the demographic information such as age, education, marital status and income of the employees while designing/offering the choices of retirement plans to them. Further studies are recommended to validate the findings of this study in terms of testing the effect of psychological social and financial perceptions on retirement planning behaviour of the employees.

This paper aims to present empirical test to analyse a structural process model based on the constructs of absorptive capacity considering sustainability aspects. It integrates dynamic capability perspective to strengthen the existing literature. Findings of the study may help organisations to renovate business processes related to absorptive capacity and improve decision-making considering sustainability attributes.

Sample for data analysis covers 389 managers of firms demonstrating some traits of sustainability orientation and operating in a developing economy like India. Structural equation modelling is applied to test a casual model.

Result of this study reveals that a formal system that drives knowledge sharing, storing and exploitation of knowledge, a structured way to appropriate and reward intellectual property rights can be fundamental to development of absorptive capacity. Such a system conducive to knowledge exploration and acquisition must lead to exploration of new knowledge sources and new knowledge. A firm’s knowledge acquisition system shall be able to deliver to acquire external as well as internal knowledge spread across departments.

This study considers commercial output as an aspect of innovative capability, so this attribute is not included in absorptive capacity.

The study may help organisations to develop a systemic approach to evolve decision-making and develop suitable processes linked to absorptive capacity considering sustainability challenges and uncertain market conditions.

The study presents a comprehensive view of absorptive capacity considering societal stakeholder’s knowledge in addition to technological and market knowledge.

There are hardly any research articles which link absorptive capacity, dynamic capability and sustainability strategies.

This paper aims to develop a scale to measure climate strategy proactivity (CSP) displayed by corporate in developing countries to attain competitive advantage (CA) and sustain it through sources of sustained competitive advantage (SOSCA). It attempts to derive sound operational definitions of CSP, CA and SOSCA through horizontal analysis of previous studies and discussions with experts and practitioners to construct a measurement scale.

Research design includes broad stages, namely, item generation, scale development and assessment of psychometric properties of the scale starting with review of literature and discussions with experts and practitioners, which were followed by a pilot and full study carried out through a cross-sectional, self-administered online survey questionnaire and assessment using suitable tools and techniques.

Findings of the study comprise development of sound operational definitions and construction of a valid and reliable measurement scale of CSP displayed by corporate to attain CA with strong psychometric properties, which is expected to be useful in developing countries not only for researchers and academics but also for the practitioners and organizations.

The information was self-reported by respondents through climate strategy proactivity questionnaire (CSPQ) and consequently can be at risk to have been influenced by bias. Nonetheless, this CSPQ scale devoid of conceptual problems can be used in developing countries in future empirical studies with the caution that its reliability and validity require further tests.

Using the CSPQ scale will help managers in developing countries in enhancing their awareness with the provision of these conceptually clear comprehensive operational definitions of CSP, CA and SOSCA with respect to the conceptual nature and the latent expressions, and draw an extensively enhanced scope of climate-conscious strategy to bring about CA.

With the data collected from a sample representing different stakeholders of Indian companies from across the country, CSPQ scale possesses significant robustness and implicative potential which can contribute to the evolution of the strategic management field by providing a valid and reliable measure of CSP in developing countries applicable under any major theoretical perspective in strategic management serving the needs of not only the empirical research but also of the management practices intended to attain CA.
