Item LEVERAGING PRETRAINED TRANSFORMERS FOR ENHANCED AIR QUALITY INDEX PREDICTION MODEL (Article PDF)(Institute of Advanced Engineering and Science, 2025) Velusamy, Santhana Lakshmi; Madhaya Shanmugam, VijayaAir pollution mitigation is essential to ensure sustainable development, as it directly affects climate change, economic productivity, and social well-being. Despite the availability of numerous prediction techniques, machine learning (ML) remains the optimal solution for forecasting air pollution. Constructing a prediction model for a region with limited data poses a challenge. This study presents a novel technique that combines temporal fusion transformer (TFT) with transfer learning to create an inventive air quality index (AQI) prediction model, effectively utilizing temporal insights and prior knowledge. The TFT is an advanced deep neural architecture engineered to enhance time series forecasting through the fusion of sequence modelling and global temporal patterns. By fusing TFT with transfer learning, the research pioneers a fresh approach to AQI prediction for region with data scarcity issue, capitalizing on cross-domain knowledge transfer. Utilizing meteorological and pollutant data from the Cochin region, a hybrid AQI prediction model is constructed through TFT and transfer learning. Employing a preexisting TFT model trained on Trivandrum data, transfer learning technique is utilized to adapt the model for predicting AQI in the Cochin region. The study demonstrates that integrating TFT with transfer learning yields superior accuracy compared to an exclusive TFT-based approach.Item PHYSICOCHEMICAL CHARACTERIZATION OF STARCH FROM MARANTA ARUNDINACEA L.

The surface morphology and physical properties of the nanocomposites were characterized using X-Ray Diffraction (XRD), High-Resolution Transmission Electron Microscopy (HRTEM), Energy-Dispersive X-Ray Spectroscopy (EDAX), Fourier-Transform Infrared Spectroscopy (FTIR), and N2 adsorption-desorption analysis. Equilibrium adsorption experiments were carried out to optimize crucial parameters such as contact time (60–360 min), adsorbent dosage (0.01–0.1 g/L), and pH (2−11) for efficient selenium ion removal. Kinetic and isotherm studies were conducted to analyze the sorption performance of the nanocomposites. The Langmuir isotherm model provided an excellent fit for the adsorption data (R2 ≥ 0.99), confirming the monolayer adsorption of selenium ions on the adsorbent surface. The maximum adsorption capacity of CC and CD composites was calculated for Se (IV) adsorption as 248.75 mg g−1 and 275.48 mg g−1, for Se (VI) adsorption as 153.37 mg g−1 and 169.64 mg g−1. Additionally, adsorption kinetics was assessed using the pseudo-second-order model, yielding high correlation coefficients (R2 ≥ 0.98). Moreover, the adsorption mechanism, regeneration ability, and the impact of co-existing anions were investigated.

Particularly, the considered system is characterized by dividing the fundamental period of periodic systems into numerous subintervals, each of which can be expressed by using matrix polynomial functions. The foremost intention of this work is to lay out a resilient controller such that the resulting closed-loop system is finite-time bounded and satisfies a mixed and passivity performance index. Furthermore, by constructing a periodic piecewise time-varying Lyapunov–Krasovskii functional, a delay-dependent sufficient condition is established in line with Wiritinger’s inequality and matrix polynomial lemma to guarantee the needed outcomes of the system under study. Following this, the gain matrix of the devised controller can be calculated by solving the established constraints. As a final step, we conclude with a numerical example that validates the potential and importance of the theoretical discoveries and the developed control scheme.Item SYNTHESIS AND ADVANCES OF SMART HETEROATOM-SITED COATINGS FOR ANTICORROSION APPLICATIONS (Article)(Taiwan Institute of Chemical Engineers, 2025-01) Swathika, M; Chandran, Sharmila; Singh Kshitij, RB; Singh, Ravindra Pratap; Pandey Shyam, S; Natarajan, ArunadeviRecently, there has been a significant interest in nanocomposites with porous structure, excellent thermal stability, and stiffness.

Pure analytical grades of boric acid (H3BO3), lithium carbonate (Li2CO3), sodium carbonate (Na2CO3) and potassium carbonate (K2CO3) are used for the preparation of LBO, NBO and KBO glasses respectively. The ABO glasses are irradiated with 100 MeV O7+ ion beam using 15 UD Pelletron tandem accelerators for fluences like 1 × 1011, 5 × 1011, 1 × 1012, 5 × 1012 and 1 × 1013 ions/cm2. The electronic energy loss is predominant and depth of propagation is calculated from SRIM and TRIM. The XRD and FE-SEM confirm the transformation of polycrystalline structure and growth of grains on the surface after the O7+ ion irradiation. LBO glasses at higher fluences revealed lithium tetrahydroxohexaoxopentaborate trihydrate with a monoclinic structure. The sharp and well-defined XRD peaks affirmed the transition from glass to glass ceramics after the irradiation. Formation of grains on the surface of the ABO glasses after the O7+ ion irradiation confirms the glass ceramics nature. KBO glasses possess enhanced stability even under ion irradiation. The optical bandgap decreased under ion irradiation. O7+ ion irradiation leads to a decrease in the tail of the Urbach energy, indicating reduced disorder in the ABO glasses. The transmission efficiency of both ABO glasses and glass ceramics is evaluated through reflection loss (Lr), transmission coefficient (T), and metallization criteria (M) and the suitability of the ABO glasses for nonlinear optical applications are discussed.Item DECIPHERING THE IMPORTANCE OF NANOENCAPSULATION TO IMPROVE THE AVAILABILITY OF BIOACTIVE MOLECULES IN FOOD SOURCES TO THE HUMAN BODY (Article)(Elsevier Ltd, 2025-02) Pugazhendhi, Arivalagan; Alshehri, Mohammed Ali Mohammed Ali; Kandasamy, Sabariswaran; Sarangi, Prakash Kumar; Sharma, AshutoshVarious bodily functions are maintained, and health benefits are provided by food-derived bioactive components. Fruits and vegetables contain numerous beneficial components, including vitamins, minerals, antioxidants, enzymes, and phytonutrients.

Findings: The results suggested the developed biopolymer-based thin film sensor showed different colours in line with the spoilage of the packed fish, which could be well correlated with the total volatile base nitrogen, microbial activity and sensory evaluation. In addition, the thin film sensors exhibited a high degree of biodegradability. The biopolymers-based thin film halochromic sensor has exhibited excellent biodegradability along with sensitiveness towards the spoilage of the packed fish. Originality/value: In the future, consumers and retailers may prefer seafood containers equipped with such halochromic sensors to determine the degree of food deterioration as a direct indicator of food quality.
