    Empowering sustainable manufacturing: unleashing digital innovation in spool fabrication industries
    (Elsevier, 2024-04-23) Sankar M. S., Kiran; Gupta, Sumit; Luthra, Sunil; Kumar, Anil; Jagtap, Sandeep; Samadhiya, Ashutosh
    In industrial landscapes, spool fabrication industries play a crucial role in the successful completion of numerous industrial projects by providing prefabricated modules. However, the implementation of digitalized sustainable practices in spool fabrication industries is progressing slowly and is still in its embryonic stage due to several challenges. To implement digitalized sustainable manufacturing (SM), digital technologies such as Internet of Things, Cloud computing, Big data analytics, Cyber-physical systems, Augmented reality, Virtual reality, and Machine learning are required in the context of sustainability. The scope of the present study entails prioritization of the enablers that promote the implementation of digitalized sustainable practices in spool fabrication industries using the Improved Fuzzy Stepwise Weight Assessment Ratio Analysis (IMF-SWARA) method integrated with Triangular Fuzzy Bonferroni Mean (TFBM). The enablers are identified through a systematic literature review and are validated by a team of seven experts through a questionnaire survey. Then the finally identified enablers are analyzed by the IMF-SWARA and TFBM integrated approach. The results indicate that the most significant enablers are management support, leadership, governmental policies and regulations to implement digitalized SM. The study provides a comprehensive analysis of digital SM enablers in the spool fabrication industry and offers guidelines for the transformation of conventional systems into digitalized SM practices.

    Implications of spectral and spatial features to improve the identification of specific classes
    (SPIE, 2019-01-14) Kallepalli, Akhil; Kumar, Anil; Khoshelham, Kourosh; James, David B.; Richardson, Mark A.
    Dimensionality is one of the greatest challenges when deciphering hyperspectral imaging data. Although the multiband nature of the data is beneficial, algorithms are faced with a high computational load and statistical incompatibility due to the insufficient number of training samples. This is a hurdle to downstream applications. The combination of dimensionality and the real-world scenario of mixed pixels makes the identification and classification of imaging data challenging. Here, we address the complications of dimensionality using specific spectral indices from band combinations and spatial indices from texture measures for classification to better identify the classes. We classified spectral and combined spatial–spectral data and calculated measures of accuracy and entropy. A reduction in entropy and an overall accuracy of 80.50% was achieved when using the spectral–spatial input, compared with 65% for the spectral indices alone and 59.50% for the optimally determined principal components.

    Solar drying of herbal wealth in Eastern Himalaya: a review
    (Global Digital Central, 2022-07-31) Chauhan, Priyanka; Pathania, Himani; Shriya, S.; Neetika, N.; Nidhi, N.; Sakshi, S.; Choudhary, Sheetal; Kumar, Rajesh; Sharma, Mamta; Rahatekar, Sameer S.; Kumar, Anil
    Solar dryers have proven to be one of the best environmentally friendly approaches for drying purpose of medicinal plants and agricultural crops. Use of solar radiations in drying purpose of plant parts has proven economically as well as environmentally responsible and sensible application. Plants are the treasure of nature with hidden medicinal properties to treat diseases. Plant material should be processed properly for extraction of medicinal molecules in terms drying to decrease the manufacturing loss and to increase the standard of product. Cognizances of ethnobotanical knowledge on plant wealth are extremely beneficial in utilization and exploration of natural resources. Conventionally, low drying temperatures between 30-40°C, with economically beneficial techniques are required to protect sensitive active ingredients. Therefore, the objective of reviewing research in medicinal plant drying is to find out optimum drying temperature and best solar dryer for drying purposes of plant parts in terms of quality and drying costs. Rendering to human requisites, solar appliances for drying purposes will be used as the best alternative to standard sun-drying technique. This review focused on effective drying is demand of present scenario for the application of heat trapped from solar radiations for drying purpose in order to maintain the quality and active ingredients of plants. Conventionally, low drying temperatures between 30-40°C, with economically beneficial techniques are required to protect sensitive active ingredients. Indirect type of solar dryers can easily fulfill all the terms for dying plant products in terms of standard and yield.

    The emergence of digitalization to the manufacturing sector in the sustainability context: a multi-stakeholder perspective analysis
    (Elsevier, 2024-08-25) Kiran Sankar, MS; Gupta, Sumit; Luthra, Sunil; Jagtap, Sandeep; Singh, Sanjeet; Kumar, Anil
    Sustainable digitalization in industry requires extensive preplanning to integrate business strategies with the concept of digitalized sustainability. However, stakeholders often have different perspectives, making alignment more challenging. Stakeholders in the digitalized sustainable manufacturing industry must be identified and prioritized for effective implementation. Therefore, the present study combines a Systematic Literature Review and Hybrid Multi-Criteria Decision Techniques, including the Full Consistency Method and Fuzzy-Evaluation based on the Distance from Average Solution method, to prioritize stakeholders' roles in digitalized sustainable manufacturing and associated strategies. This study explores various implementation methodologies and their relations to different stakeholders. It categorizes stakeholders, such as manufacturers, research and development teams, managers, mergers and acquisitions, education programs, the 6R strategy, and eco-efficiency, to illustrate corresponding strategies. Overall, the study highlights the urgent need for meticulous planning to synchronize business strategies with digitalized sustainability while recognizing the difficulty in harmonizing different stakeholders' assessments. The research findings offer valuable insights for industry professionals aiming to navigate the complexities of sustainable digitalization successfully.

    Understanding of colistin usage in food animals and available detection techniques: a review
    (MDPI, 2020-10-16) Kumar, Harsh; Chen, Bing-Huei; Kuca, Kamil; Nepovimova, Eugenie; Kaushal, Ankur; Nagraik, Rupak; Bhatia, Shashi Kant; Dhanjal, Daljeet Singh; Kumar, Vinod; Kumar, Anil; Upadhyay, Navneet Kumar; Verma, Rachna; Kumar, Dinesh
    Progress in the medical profession is determined by the achievements and effectiveness of new antibiotics in the treatment of microbial infections. However, the development of multiple-drug resistance in numerous bacteria, especially Gram-negative bacteria, has limited the treatment options. Due to this resistance, the resurgence of cyclic polypeptide drugs like colistin remains the only option. The drug, colistin, is a well-known growth inhibitor of Gram-negative bacteria like Acinetobacter baumanni, Enterobacter cloacae, Klebsiella pneumoniae, and Pseudomonas aeruginosa. Technological advancements have uncovered the role of the mcr-1(mobilized colistin resistance) gene, which is responsible for the development of resistance in Gram-negative bacteria, which make them distinct from other bacteria without this gene. Additionally, food animals have been determined to be the reservoir for colistin resistance microbes, from which they spread to other hosts. Due to the adverse effects of colistin, many developed countries have prohibited its usage in animal foods, but developing countries are still using colistin in animal food production, thereby imposing a major risk to the public health. Therefore, there is a need for implementation of sustainable measures in livestock farms to prevent microbial infection. This review highlights the negative effects (increased resistance) of colistin consumption and emphasizes the different approaches used for detecting colistin in animal-based foods as well as the challenges associated with its detection
