- A Blockchain and IoT-Driven Solution for Farmers December 19, 2024
Farming is often regarded as an occupation that is challenging and has become a sobriquet for hardship and unpredictability, leaving farmers financially vulnerable and many a times at the brink of poverty. Insuring crops can, however, minimise the risk of loss, making it a viable option as long as the process doesn’t get bogged down by excessive bureaucracy and cumbersome paperwork. Dr Naga Sravanthi Puppala, Assistant Professor at the Department of Computer Science and Engineering has come up with a game-changing solution of utilising blockchain technology and real time IoT data for automatic and quick coverage of crops by simplifying the insurance process thereby helping reshaping the future of agriculture, just when it’s needed most.
Abstract
The invention is a groundbreaking design patent that employs a single, sophisticated smart contract policy to autonomously manage the entire crop insurance process. This system innovatively combines blockchain technology with real-time IoT data collection to create an efficient, transparent, and reliable insurance solution for farmers. Central to this invention is a singular smart contract policy designed to oversee every stage of the insurance lifecycle, from policy issuance and dynamic risk assessment to claims processing and payout disbursement. This smart contract policy is meticulously programmed with specific conditions and thresholds, including weather patterns, soil moisture levels, and crop health indicators, all monitored by IoT devices in the field. As these conditions are tracked in real-time, the smart contract policy autonomously adjusts coverage and triggers payouts when necessary, eliminating the need for human intervention. This system not only enhances efficiency by reducing administrative costs but also ensures prompt and accurate payouts. By relying on tamper-proof data and predefined conditions, the invention offers a secure and transparent approach to crop insurance, providing farmers with a dependable safety net against crop losses.
In short, this invention makes crop insurance smarter, simpler, and fairer, giving farmers the support they need when they need it most.Practical Implementation and Social Implications of the Research

The practical applications of the research in sectors such as electric vehicles and residential power systems, contribute to a more reliable and sustainable energy future contributing to a more reliable and sustainable future.
Abstract of the research.
This paper introduces novel high-gain tertiary port boost converter (HGTPBC) designed for hybrid energy sources such as solar photovoltaic (PV) and fuel cells (FC). The converter is employed with dual input sources by facilitating modular converters and accomplishes a high step-up voltage gain by virtue of a voltage multiplier in a DC microgrid, where the prosumers can have an islanded operation. The proposed topology allows home appliances to be powered by multiple energy source without the need for a large storage unit. Key features include continuous input current, reduced normalized voltage stress on switches, expandability for multiple input sources and independent source control. The independent control facilitates the standalone operation with single source during source failure or absence. To evaluate the converter performance, a thorough steady-state analysis, both with and without consideration of nonidealities is carried out. Detailed comparisons with existing converter topologies highlight the advantages of the proposed converter. Moreover, the loss distribution and efficiency analysis of proposed converter are presented and found to be 91.59% efficiency at rated power. Theoretical aspects are validated through hardware testing on a 100W laboratory prototype.
Explanation of the Research in layperson’s terms.
The proposed converter is a 100W DC-DC converter topology used in hybrid energy systems applications and electric vehicular applications in DC microgrid. The converter can accept two sources like fuel cell and solar PV system to supply the load and even can be extended for a greater number of sources. Thus, it is suitable for various applications of traction vehicles, household electrifications etc. It exhibits a lower switch stress and higher step-up conversion gain.
Practical Implementation and Social implications
The features include high step-up conversion gain, independent control possible, reduced normalised switch voltage stress. And flexible operation based on PV availability. It is most suitable for electric vehicles, Unmanned ariel vehicles, and hybrid energy systems etc. It improves the reliability of the renewable energy source by the incorporation of the second fixed source, fuel cell. It can be used in various on-grid and off-grid applications like home, hospitals, offices, and educational institutions, especially where source reliability is necessary. The major advantage is the reduction in the size of the source due to higher step-up gain and ease of control between the sources.

In an inspiring collaboration, Prof. G S Vinod Kumar and Prof. Sheela Singh from the Department of Mechanical Engineering, Prof. Ranjit Thapa from the Department of Physics, and Dr Rajapandiyan Panneerselvam from the Department of Chemistry at SRM University – AP, along with PhD scholars Ms Harsha K and Ms Arunima J, have co-authored a compelling paper titled “Innovative Approaches to Enhancing the Tarnish Resistance of Silver Alloys.” This groundbreaking research focuses on developing new silver alloys that resist tarnishing, enhancing durability and aesthetic appeal for applications in the jewellery industry. Together, they are paving the way for innovative solutions that blend science with artistry.
Abstract
Silver and its alloys undergo tarnishing with time, which is a black stain on the surface due to the formation of Ag2S. Developing a tarnish resistant Ag alloy was attempted by alloying Ag with elements that form a passive oxide layer on the surface. Germanium is proven to provide better tarnish resistance to sterling silver alloy (92.5wt.% pure) which is available under the trade name of Argentium©. The present work investigates the tarnish resistance behaviour of sterling silver alloy (92.5wt.% pure) containing various additions of Copper, Zinc, Germanium, Aluminium, Beryllium, Titanium, Zirconium, and Magnesium. The alloys were prepared by melting and casting route, followed by Passivation Heat Treatment (PHT) to create a stable and continuous oxide layer. The temperature for PHT was optimized using thermogravimetry analysis (TGA) of the alloys prepared. An accelerated tarnish test was carried out to investigate the tarnishing behaviour of alloy samples obtained before and after PHT. The samples were characterized using XRD, SEM-EDX, TG-DSC, micro-Raman Spectroscopy, and XPS. The change in reflectance of the samples after the tarnish test is determined using UV-visible reflectance spectroscopy. The mechanism behind the tarnish resistance was derived using Density Functional Theory (DFT) by comparing sulphur (S2) and Oxygen (O2) adsorption energies (BE) of the alloying elements.
Explanation of the Research in layperson’s terms
Age-old silver pieces are found in different colours ranging from light yellow(silver Jewellery pieces after a few weeks of usage) to black(archaeological silver pieces). They look different in terms of the metallic white colour and lustrous appearance from fresh silver. This demeans silver and thus affects its market. The major cause of the staining of silver is the interaction of individual silver particles with some elements found common in the atmosphere. We work on the prevention of this staining of silver. For the study, silver is incorporated with other elements which makes silver less interacting with staining elements in the atmosphere. These additional elements create a layer over silver so that it is protected. The appropriate elements are identified by using modelling using computer software. After obtaining appropriate elements, the experimental trials are also done with the same elements until stainless silver is obtained. Then, what happens to the added elements inside silver is also studied by using modern microscopic technics.
Practical/Social Implications of the Research
The major application of the invention is in the jewellery industry. The problem of tarnishing is an age-old threat in jewellery making. The alloys we proposed could be used to make quality silver jewellery/articles that can sustain the colour and lustre for a longer period. This will stop the hesitation from jewellery designers and industries to try intricate designs in silver and find a better market for them. The alloys based on the proposed composition show good grain refinement and thus high hardness. This strengthens the soft silver and improves the range of its applications from low hardness articles to high. The alloys based on the proposed composition have high tensile strength. They deform plastically for a wide range of stress values and will not break easily.

Their research titled, “System And Method For Real-Time Detection And Classification of Defects in Assembled Printed Circuit Boards (PCBA)” was published in the Patent Journal with Application number 202441045761.
Abstract:
This study presents a new system for real-time detection and classification of defects in Assembled Printed Circuit Boards (PCBAs), which are critical in electronic products and systems. It employs an efficient model with pretrained weights to detect defects for enhanced quality control. The model is initially trained and fine-tuned on a computer, then deployed on a compact computing board. For real-time imaging, a high-definition USB camera is connected to the system, allowing direct defect identification without the need for external devices. The output is shown on a monitor, with the PCBA image featuring clearly labeled boxes to indicate the type and location of defects. This method offers a streamlined approach to defect classification, helping to improve the quality control process in electronics manufacturing.
Explanation of the Research in layperson’s terms:
This research focuses on finding defects or flaws in Assembled Printed Circuit Boards (PCBAs). Which are the “backbone” of most electronic devices, like computers and phones. This system uses a powerful computer model to “look” at these boards and quickly identify any defects, like missing holes, mouse byte, open circuit, short circuit, spur and spurious copper in real-time. The research starts by training this model using a deep learning object detection model on a regular computer, teaching it to recognize what a normal PCBA looks like and what various defects might look like. Once it’s ready, we transfer the model to a small, efficient computer edge board, which does all the processing. A camera is used to capture images of the PCBAs, and the system analyzes these images to find respective defects. The results are displayed on a screen, where it clearly marks where the defects are and what kind of defects they are. Overall, this system helps companies detect defects in their electronics manufacturing process quickly and accurately, which can save time, reduce waste, and improve the quality of their products.
Practical Implementation:
The practical implementation of our research involves deploying a system for real-time detection and classification of defects in Assembled Printed Circuit Boards (PCBAs) a crucial component in nearly all electronic devices. By using advanced Deep learning techniques, our system can quickly identify manufacturing defects, allowing electronics manufacturers to detect the defect early in the production process. This can lead to significant improvements in quality control, reduced waste, and lower production costs. By improving quality control in electronics manufacturing, the system can help reduce electronic waste, which is a significant environmental concern. Early detection of defects also reduces the chances of faulty electronic products reaching consumers, thereby improving safety and reducing the need for product recalls. Additionally, the efficiency and accuracy of our system could lead to more reliable electronics, contributing to greater consumer trust in electronic products. This, in turn, could encourage companies to invest in higher-quality manufacturing processes, ultimately leading to a more sustainable and responsible electronics industry.
Collaborations:
To develop our system, we first trained a computer model to recognize defects in Assembled Printed Circuit Boards (PCBAs). This training process involved feeding the model a large dataset of PCBA images, some with defects and some without. By analyzing these examples, the model learned to identify common defects, like Missing hole, mouse byte, open circuit, short circuit, Spur and Spurious copper. Once the model was trained, we implemented it in a real-time setting. This meant integrating it with equipment that could inspect PCBAs as they were being produced. The system used a camera to capture images of each PCBA and then applied the trained model to analyze those images, checking for any defects. With the model running in real-time, the system could immediately detect issues and alert the manufacturing team, allowing them to correct problems on the spot. This approach helped improve the quality of the final product and reduced the chances of defective electronics reaching consumers. It also sped up the quality control process and reduced waste, making the entire manufacturing process more efficient.
Future Research Plans:
Our future research plans focus on enhancing and expanding our system for defect detection in Assembled Printed Circuit Boards (PCBAs):
Model Optimization: We aim to further refine our machine learning model to improve accuracy and speed. This includes experimenting with different architectures and training techniques to boost performance.
Expanded Defect Library: We plan to gather a more extensive dataset of PCBA defects, allowing our model to identify a wider range of issues. This will make the system more versatile and capable of handling various manufacturing environments.
Real-World Testing: We intend to test our system in a broader range of manufacturing settings to ensure its robustness and adaptability. This will help us understand how it performs in diverse real-world scenarios and how we can fine-tune it for optimal results.
Integration with Manufacturing Systems: Our goal is to integrate our system with other manufacturing processes and technologies. This will allow for seamless communication between defect detection and other quality control systems, enhancing the overall manufacturing workflow.
Automation and Robotics: We’re interested in exploring the use of automation and robotics to streamline the defect detection process. This could lead to a more automated manufacturing line, reducing human intervention and potential errors.

Dr Manaswini Sen, Assistant Professor at the Department of History, has published an insightful paper tracing the ideological and intellectual output of women trade unionists in late colonial Bengal. Her research paper titled “(Re)Inventing Feminism within the Discourse of Class Struggle: Women and Intellectual History in the Trade Union Movement of Late Colonial Bengal (1920–1947)”, published in the prestigious Journal of the History of Women Philosophers and Scientists, offers a novel perspective on understanding the class struggle, anticolonial discourse in the patriarchal society of colonial Bengal.
Abstract
This paper envisages (re)constructing the intellectual praxis of women trade unionists in late colonial Bengal. By arguing how political practice habitually translates to political thought, the paper devises a methodology to address the gendered discourse of intellectual history in the Global South. It focuses on intellectual output, primarily journal articles of women trade unionists like Santoshi Kumari Gupta, Maitreyee Bose, and Kanak Mukherjee, to trace a genealogy of how class struggle was perceived by women labour activists across the ideological spectrum of nationalism, socialism, and communism between 1920 to 1947 in Bengal. The piece is an effort to transcend the manifold marginalisations that plague the establishment of feminine political praxis within the regulating structures of colonialism and capitalism. In the process, it bids to unfold an alternative narrative of the anti-colonial, anti-capitalist, and anti-patriarchal narrative of the decolonisation of South Asian intellectual thought.
Research, Collaboration and Future Research Plans
The research strives to bring to the forefront the intellectual contributions of three female trade unionists in the late colonial period to trace the evolution of discourses on anticolonial class struggle from a gendered perspective. With the global turn in intellectual history, there is an augmented effort at amplifying the ‘small voices of history’. The inherent socio-cultural predicaments in our society make it inordinately challenging to trace conventional sources for mapping the intellectual endeavours of women. This paper aims to rectify this gap by reconstructing women labour activists’ intellectual practises and literary output in the early 20th century. In the process, the research tries to bring forth narratives of anticolonialism, which drowns in the overwhelming presence of nationalism in the discourses of decolonisation of South Asia. This paper was the result of academic exchanges with professors of Benaras Hindu University, Dr B.R. Ambedkar University, Delhi, and the University of Paderborn, Germany.
Dr Sen primarily researches marginal anticolonial epistemological traditions of South and South East Asia. Her thesis on the evolution and dissemination of socialism in late colonial Bengal, which focuses on an intellectual history of trade unionism, forms the basis of her first monograph. However, she is now focusing on the transnational and transcontinental intellectual networks of a wide spectrum of leftist labour activists and proto-nationalists and the ways these fringe intellectual traditions interacted with each other and nationalism. Based on a rich archive across India and Europe and a plethora of alternative sources, she tends to devise new methodological interventions in the field of Global Intellectual History, making labour history more accessible and relevant in scholarly circles.
