Online learning environments are dynamic and scattered, making user activity evaluation difficult for e-learning systems. This study proposes an autonomous and intelligent evaluator utilizing Stacking Ensemble Federated Learning (SEFL). First, each compute node trains locally on its dataset using eight CNN architectures (DenseNet169, MobileNetV2, Xception, VGG16, ResNet50, DenseNet121, and...

This research explores a smart, wireless, Internet of Things (IoT)-based system to monitor a 125-watt photovoltaic (PV) module. The proposed system continuously monitors current, voltage, irradiance, and temperature, addressing challenges posed by fluctuating solar output due to environmental conditions, panel status, and dirt accumulation. A Wi-Fi-enabled microcontroller ensures the persistent...

Wet-chemical process to prepare the ZnO nanoparticles, and this were then incorporated in different proportions of weight to a poly (methyl methacrylate) (PMMA) matrix. Bulk ZnO particles were also embedded in PMMA for comparison. The structural and vibrational properties of the composites were investigated using X-ray diffraction (XRD), Fingerprint Raman spectroscopy (RS), and high-resolution...

This study evaluated the performance of machine learning algorithms in classifying mental workload among 74 undergraduate students (aged 19–22) during a controlled multitasking experiment conducted on the LabintheWild platform. Immediately following the task, participants self-reported their perceived workload using the NASA Task Load Index (NASA-TLX), rating six dimensions-Mental Demand,...

Biodiesel obtained from renewable sources is an auspicious alternative to regular diesel due to its sustainability and low environmental impact. This study examines the influence of carbon nanotube (CNT) additives on the operation and emission features of a compression ignition engine using Hevea Brasiliensis biodiesel (HBBD20) fuel along with CNT mixed blends (HBBD20 CNT 30 ppm, HBBD20 CNT 60...

Herbal alternatives are increasingly explored in periodontal therapy to minimize the adverse effects associated with conventional antimicrobials. This animal study evaluated the efficacy of 15% Tridax procumbens gel (Group A) in experimentally induced periodontitis using a split-mouth design in four male rabbits, with 2% chlorhexidine gel (Group B) as the control. Periodontitis was induced using...

This study explores the potential of using electronic waste (e-waste) as an alternative to traditional coarse aggregates (CA) in concrete production to address the growing concerns of e-waste accumulation and the depletion of natural resources in the construction industry. The research evaluates the sustainability, durability, and structural performance of concrete mixtures with e-waste...

Drug discovery has traditionally been constrained by time-intensive and cost-prohibitive experimental screening. The proposed study introduces an Explainable Generative Multi-Objective Framework (EGMOF) for end-to-end drug discovery. The framework combines four major modules: (1) Data Preprocessing and Representation using MolFormer for molecular embeddings and ProtT5 for protein sequence...

: High Density Polyethylene (HDPE) plastic is one of the most resistant manmade polymers, posing significant environmental challenges. In this study, microbes capable of growing on this recalcitrant plastic were isolated from soil samples collected from plastic contaminated areas. The isolated Bacillus pseudomycoides utilized High-Density Polyethylene (HDPE) of 75 microns as the sole carbon...

The focusing behavior of an azimuthally polarized, axisymmetric Bessel-modulated Gaussian (QBG) beam through dielectric interface using vector diffraction theory in a high-numerical-aperture system. The results indicate that the intensity pattern in the focal region can be significantly controlled by the beam parameter ????. In contrast, the parameter ???? strongly affects the axial intensity...

The plants have been known to synthesize bioactive compounds that can be used to treat diseases. Phytochemicals in seeds, including alkaloids, flavonoids, and polyphenols, possess anti-inflammatory, antioxidant, and antidiabetic activity. The clearing-nut tree (Strychnos potatorum Linn.) has been traditionally used in Ayurveda and traditional medicine to treat diseases of the eye, liver and...

Lung cancer is one of the leading causes of cancer-related deaths worldwide, making early and accurate detection essential. This study presents a CNN-based framework using the pre-trained VGG16 model for automated lung cancer classification from chest CT scans. The approach performs both binary (cancerous vs. non-cancerous) and multi-class classification of four subtypes: Adenocarcinoma, Large...

Hybrid isolation–damping systems improve structural resilience under near-fault ground motions, yet their application to plan-irregular buildings with strong torsional effects remains limited. This research investigates the seismic resilience of reinforced concrete (RC) frame buildings having plan irregularities. Fixed-base and lead rubber bearing (LRB) isolated models were developed employing...

Air pollution has now become one of the major ecological problems in the Indian cities that has several negative effects on human health and environment. This study developed and tested an Artificial Neural Network (ANN) to predict multi-pollutants in five cities of Madhya Pradesh, i.e. Bhopal, Dewas, Indore, Jabalpur and Ujjain, to examine the city-specific pollutant concentration and...

Perilla frutescens (L.) Britt. leaves contain many published bioactive compounds. In this study, caffeic acid (CA) was isolated from Perilla frutescens (L.) Britt. leaves were demonstrated to have anti-inflammatory properties through zymosan in Raw 264.7. CA was evaluated by HPLC. TNF-α, IL-6, IL-1β, and IL-10 stimulated by zymosan were significantly inhibited by pretreatment with CA (40...
