The Department of Physics is thrilled to announce a remarkable milestone in sustainable technology. Dr Sabyasachi Mukhopadhyay, Associate Professor and Ms Sreelekha Bhuvaneswari, BSc student has been officially granted a patent for their groundbreaking invention: “A fibre material with moisture retention capacity with thermal tolerance and a method for manufacture of the same.”

This pioneering material, distinguished by its Application Number 202141023375, stands at the forefront of cooling technology. It promises to enhance thermal regulation while prioritising environmental sustainability.

Dr Mukhopadhyay’s invention is poised to make significant contributions to the field of material science, offering a versatile solution that holds potential applications across various industries. The department extends its heartfelt congratulations to the duo on this significant achievement and looks forward to the positive impact his work will continue to have on our community and beyond.

Abstract:

The project, with the patent application number 202141023375, develops a methodology to design a fabric cloth that would replace the use of air conditioners. This cloth design is inspired by Saharan silver ants which regulate their body temperatures in the scorching desert heat and also from the cooling properties of clay. This research would significantly scale down the usage of AC and other cooling devices in warm places, thus reducing the use of electricity and emission of greenhouse gases to the environment. As this cloth would be environment friendly with long durability and cost-efficiency, Sreelekha hopes that this research would bridge the socioeconomic divide of haves and have-nots between communities.

Explanation of the Research in Layperson’s Terms :

Using room conditioning AC during these times, especially with lower temperatures is very risky. Virus spread with closed circulated air or prolonged cold temperatures while breathing, so thus using air conditioning is bad. With this in mind, we need an efficient way of cooling in the snoring temperatures. We propose developing a fabric that integrates clay (Its primary mineral is kaolinite; clay may be generally described as 40% aluminium oxide, 46% silicon oxide, and 14% water.) in its synthesis; clay is known for its cooling properties given enough water to retail and proper reflection techniques for heat throughout the fabric inspired from uniquely shaped hairs with triangular cross-sections as in arrangement employed by the Saharan silver ants. This model not only conserves energy compared to room cooling but also is very practical, wherein we can dampen the fabric with the least water and retain its cooling for long hours. This Fabric could be employed in a variety of settings, for example, in making carpets and curtains in a house to keep the room temperature regulated.

Practical Implementation and Social Implications:

The research would significantly scale down the usage of AC and other cooling devices in warm places, thus reducing the use of electricity and emission of greenhouse gases to the environment. As this cloth would be environment friendly with long durability and cost-efficiency, Sreelekha hopes that this research would bridge the socioeconomic divide of haves and have-nots between communities.

Dr Soni Wadhwa, Assistant Professor at the Department of Literature and Languages and her research scholar, Ms Jintu Alias, from the Easwari School of Liberal Arts at SRM University-AP, have published their seminal research paper titled “Provincialising Island Poetics: The Personal as the Spatial in N S Madhavan’s Litanies of Dutch Battery.”
Their research delves into the intricate relationship between personal experiences and spatial representations, challenging traditional island narratives. Focusing on the island city of Kochi and its rich history of cosmopolitanism, they aim to draw attention to alternative island spaces in India and Asia. Furthermore, they are convinced that their work will inspire further studies and creative writing on cultural traditions in smaller Indian island cities, highlighting the diverse themes and settings that are yet to be explored in Indian literature.

Abstract

Affect towards islands is a unique approach to engage with in discussions of the phenomenology of fictional islands. This affect complements the already identified tropes within island poetics: those of sensorial exploration, spatial practices, and textural detailing of islands. This article turns to a work of fiction about a fictional island based on the island city of Kochi in south India to unpack an alternative aesthetic of spatiality, the kind that changes the personal/political relationship to personal/spatial one. We argue that the novel, Litanies of Dutch Battery (the novel in question) by N.S. Madhavan, expands inquiries into phenomenology of fictional islands by making space for corporeal memory and collective memory in storytelling. These memory-oriented narrative devices, we suggest, “provincialize” island poetics to add a hermeneutic of postcolonial angst to the repertoire of formal features of literary islandness.

Abstract

In this research paper, we propose an unsupervised framework for feature learning based on an autoencoder to learn sparse feature representations for EEG-based person identification. Autoencoder and CNN do the person identification task for signal reconstruction and recognition. Electroencephalography (EEG) based biometric system is vesting humans to recognise, identify and communicate with the outer world using brain signals for interactions. EEG-based biometrics are putting forward solutions because of their high-safety capabilities and handy transportable instruments. Motor imagery EEG (MI-EEG) is a maximum broadly centered EEG signal that exhibits a subject’s motion intentions without real actions. The Proposed framework proved to be a practical approach to managing the massive volume of EEG data and identifying the person based on their different task with resting states.
