Energy–Cost–SLA Aware Cloud Scheduling via Adaptive Non-dominated Sorting Genetic Algorithm-III and Neighborhood Refinement Vijayasekaran G., Sathya V., Sumathi S., Lavanya M. Journal of Trends in Computer Science and Smart Technology, 2026 The optimization of resource allocation in a cloud computing environment is a problem that has been challenging due to heterogeneous tasks with varying resource requirements and different optimization objectives for execution time, energy consumption, service level agreements (SLAs) and so on. In this paper, a hybrid multi-objective optimization algorithm called AH-NSGAIII-VND is proposed for solving a multi-objective optimization problem in a cloud computing environment. The proposed algorithm integrates a global search process using a variant of a multi-objective evolutionary algorithm called Non-Dominated Sorting Genetic Algorithm III (NSGA-III) and a local search process using a variant of a local search algorithm called Variable Neighborhood Descent (VND). The problem of resource allocation in a cloud computing environment is formulated as a multi-objective optimization problem considering makespan, energy consumption, cost, service level agreements (SLAs) and resource utilization. Researchers compared the results of the PSO, GA, and GWO optimization methods to the baseline using CloudSim-based model conditions on the changing workload scale. Experimental results indicate that cloud supply governance efficiency is enhanced with the AH-NSGAIII-VND architecture. It achieves around 11.3%, 12.8%, and 28% lower costs than the baseline NSGA-III approach while increasing overall asset utilization by over 5 percentage points. Moreover, with increasing workload, the proposed model exhibits improved convergence behavior and scalability. These results confirm that global evolutionary optimization supported by adaptive local search successfully reinstates or enhances the efficiency of resource allocation.
A hybrid deep learning framework for early detection of diabetic retinopathy using retinal fundus images Mishmala Sushith, A. Sathiya, V. Kalaipoonguzhali, V. Sathya Scientific Reports, 2025 Recent advancements in deep learning have significantly impacted medical image processing domain, enabling sophisticated and accurate diagnostic tools. This paper presents a novel hybrid deep learning framework that combines convolutional neural networks (CNNs) and recurrent neural networks (RNNs) for diabetic retinopathy (DR) early detection and progression monitoring using retinal fundus images. Utilizing the sequential nature of disease progression, the proposed method integrates temporal information across multiple retinal scans to enhance detection accuracy. The proposed model utilizes publicly available DRIVE and Kaggle diabetic retinopathy datasets to evaluate the performance. The benchmark datasets provide a diverse set of annotated retinal images and the proposed hybrid model employs a CNN to extract spatial features from retinal images. The spatial feature extraction is enhanced by multi-scale feature extraction to capture fine details and broader patterns. These enriched spatial features are then fed into an RNN with attention mechanism to capture temporal dependencies so that most relevant data aspects can be considered for analysis. This combined approach enables the model to consider both current and previous states of the retina, improving its ability to detect subtle changes indicative of early-stage DR. Proposed model experimental evaluation demonstrate the superior performance over traditional deep learning models like CNN, RNN, InceptionV3, VGG19 and LSTM in terms of both sensitivity and specificity, achieving 97.5% accuracy on the DRIVE dataset, 94.04% on the Kaggle dataset, 96.9% on the Eyepacs Dataset. This research work not only advances the field of automated DR detection but also provides a framework for utilizing temporal information in medical image analysis.

Optimizing combustion efficiency and emission reduction in low temperature combustion engines using biodiesel-nano additive alcohol blends: A review C. Vijai, Dinesh Babu M, Naresh Babu M, Sathiyamoorthi R, Sathyanarayanan S, Sathya V, KamakshiPriya K, Habtamu Alemayehu Results in Engineering, 2025 The increasing levels of harmful emissions and the depletion of fossil fuel resources have sparked global interest in biodiesel as an alternative fuel. This review explores the potential of biodiesel derived from non-edible resources and waste products, enhanced by nano-additives and higher alcohol fuels, to support Low Temperature Combustion (LTC) engine technologies. Nano-additives like titanium dioxide and magnesium oxide enhance fuel properties, while higher alcohols reduce soot and hydrocarbon (HC) emissions. Advanced combustion modes are used to minimize nitrogen oxide (NOx) and particulate emissions. This review underscores the significant role of biodiesel with additives in enhancing lower combustion, although Low temperature combustion engines demand advanced control over fuel composition and combustion conditions for optimal performance. Effective strategies like Exhaust Gas recirculation (EGR) and Variable Injection Timing helps in controlling the harmful emission levels in LTC Engines. EGR reduces NOx emissions but increases HC and CO beyond 30%. Early injection rates (before 23° BTDC) increased NOx, while late injection (after 27° BTDC) increases HC and CO. Combining EGR (15-25%) with optimized injection timing (23°-27° BTDC) provides the best emission control in LTC engines. Hence Blending biodiesel, alcohols, and nano-additives helps to reduce emissions in LTC engines. It was found that Higher alcohols improve combustion efficiency, reduce NOx & PM, but increase CO & HC at high blends while with addition of Nanoparticles optimization of combustion, lower emissions, and enhancement of thermal efficiency are achieved. n-Pentanol and Copper Oxide (CuO) were found to be better Alcohol and Nanoparticle additive with respect to High energy content, Better Volatility and Stability, enhanced combustion and Emission control. Within the LTC strategies RCCI was found to be best with respect to maximum thermal efficiency, lower emissions, superior load adaptability which is a concern in HCCI and PCCI modes and fuel flexibility to be used in a wide range of fuel combinations to optimize combustion efficiency, emissions, and performance. However, trade off exists between NOx and HC levels even with enhanced combustion which can be controlled with optimized combustion chamber design, optimized fuel injection system with proper Air Fuel Ratio and after treatment systems like SCR and DPF.
Sunflower-based butterfly optimization algorithm with enhanced RNN for the harmonics elimination in multilevel inverter V. Mohan, G. Krithiga, M. Thamil Alagan, V. Sathya Discover Applied Sciences, 2025 Multilevel inversion describes a power conversion technique that reduces Total Harmonic Distortion (THD) by gradually increasing the output voltage and approaching a sine wave. The fundamental goal of Multi Level Inverters (MLIs) is to produce an approximate sinusoidal voltage from many levels of dc voltages, which are typically supplied from capacitor voltage sources that convert DC input voltage to AC output voltage. A key goal is to obtain a pure sinusoidal waveform at the output of the Multi Level Inverter (MLI). In a cascaded MLI, the Selective Harmonic Elimination (SHE) and Pulse Width Modulation (PWM) approach is employed to mitigate lower harmonics by maintaining the needed fundamental voltage. To determine Switching Angles (SA), an objective function is generated from the SHE problem. In this paper, the Sunflower based– Butterfly Optimization Algorithm (SF-BOA) is presented as a method for evaluating transcendental nonlinear equations using an MLI in a SHE approaches. SF-BOA’s optimized switching angle is used for 11-level three-phase PWM control using the Cascaded H Bridge architecture for harmonic reduction of the entire modulation index. Although Artificial Intelligence (AI) systems can effectively solve a non-linear transcendental equation, their time consumption together with the convergence capability differs. Enhanced Recurrent Neural Network (ERNN) shows a kind of recurrent neural network in which the hidden neurons are tweaked by SF-BOA with the goal of minimizing THD. As per the simulation data, the SF-BOA approach is much appropriate and suitable than other compared algorithms like Harris Hawks Optimization (HHO), Whale optimization algorithm, Marine Predator Algorithm (MPA), Multi Group Marine Predator Algorithm (MGMPA).

A., V. Sathya AI Methods for Environmental Protection and Resource Conservation, 2025 Environmental modeling has a major importance in analyzing the changes in the environment, climate, and resource allocation. The current environmental models with the use of new technologies such as AI, machine learning, big data, and IoT improves the precision of climate change predictions, emissions, protection of species, and prevention of calamites. These models use data and information generated in real-time and computer models to arrive at policy recommendations. However, there are some limitations like data uncertainty, computational complexity, and the gaps between the existing and implemented policies that reduce their efficiency. Future research needs to address the issues of combining different types of AI, continuous monitoring of the AI-driven processes, and sharing of AI models due to the concerns related to the accessibility and accuracy of the results. At the international level, the development of environmental modeling hence requires interventions from interdisciplinary fields as the policy frameworks.
