The diagnostic solutions offered by the present artificial intelligence (AI) solutions suffer from non-generalizability and heavy reliance on complex models. In an attempt to solve these issues, we propose a lightweight yet versatile method consisting of a combination of ResNet50 transfer learning and hybrid machine learning. Image features are extracted using dermoscopy, magnetic resonance imaging (MRI), and histopathological images. These are subjected to principal component analysis (PCA) dimensionality reduction followed by classification using support vector machine (SVM), random forest (RF), logistic regression (LR), and XGBoost algorithms. This segregation of the two processes improves efficiency. The hybrid approach using ResNet50 + LR yielded an accuracy of 91.01% in the case of breast cancer detection compared to 86.26% of a baseline convolutional neural network (CNN). Also, ResNet50 gave an accuracy of 96.61% in diagnosing skin cancer. Custom CNN provided an accuracy of 99.42% for lung cancer and 96.33% for brain tumor detection.

This paper deals with an active front-end converter (AFEC) for a 5-ϕ inverter-fed induction motor (IM) drive. Multi-phase IM drive stands as an evolving domain of electrical drive usages. Supply from the grid is prone to be unbalanced and affects the input power quality of adjustable multi-phase IM drives. This work proposes a fuzzy logic control strategy with the space vector pulse width modulation (SVPWM) switching scheme for the AFEC outer voltage control along with inner current control loops for attenuating the disturbances due to voltage unbalance conditions. This method of control can keep the power factor nearby unity on the AC side with sinusoidal AC current and constant DC voltage at the DC link capacitor. A 5-ϕ inverter designed with SVPWM for IM drive enables operation of the drive with reduced percentage total harmonic distortion (THD) in the voltage of output side. This SVPWM control for a 5-ϕ voltage source inverter (VSI) uses entire voltage of the DC bus and the output responses are more efficient having a minimal lower order THD. The dynamic performances of a 5-ϕ VSI fed IM drive are investigated. The simulation results show the system has an improved power factor at the front-end, constant DC voltage across the capacitor, low THD at the input current, and a superior output performance for the 5 phase IM based drive.

Renewable energy integration causes intermittency, nonlinear dynamics, and grid-code restrictions in modern power systems. Although hybrid renewable energy systems combining wind, photovoltaic, and fuel cell sources increase energy availability, conventional control approaches often fail to maintain voltage stability, power quality, and rapid fault recovery under varying operating conditions. High renewable penetration and noisy conditions worsen these concerns. Existing methods typically address voltage regulation, transient stability, fault resilience, and power sharing independently using fixed or offline-tuned controllers, limiting adaptability during grid disturbances. To overcome these challenges, this study proposes an AI-enhanced STATCOM-controlled hybrid renewable energy system with learning-based control, predictive stability assessment, and multi-agent coordination. Adaptive reactive power support, noise-resilient fault detection, renewable source power sharing, predictive voltage regulation, and physiologically inspired transient stability prediction using hierarchical reinforcement learning. The simulation results maintain system voltage deviation within ±2%, harmonic distortion below 2%, fault detection within 7 ms, and transient stability prediction accuracy above 98% across varied operating conditions. Voltage recovery, overshoot suppression, and resource utilization efficiency improve above benchmark techniques. Thus, findings demonstrate that AI- enhanced STATCOM works as cognitive grid-interfacing agents rather than passive compensators for improving stability, power quality, and operational resilience in various deployment settings.

10.11591/ijape.v15.i3.pp1253-1263
Naveena Sandhadi , Srinu Naik Ramavathu
The growing demand for electric vehicles (EVs) has intensified the need for high-efficiency, reliable, and user-friendly wireless charging systems. Conventional wired chargers and existing wireless solutions often suffer from high losses, poor power quality, and limited control accuracy under dynamic operating conditions. To address these challenges, this paper proposes an advanced wireless charging architecture integrating a three-phase Vienna rectifier, high-frequency inverter, and isolation transformer. A three-phase frequency inverter and a three-stage synchronous rectifier further enhance conversion efficiency. Precise voltage and current regulation is achieved using a cascaded fuzzy controller (CFC) combined with a proportional-integral (PI) controller. MATLAB simulations demonstrate unity power factor, improved efficiency, and stable performance under varying load conditions. The results confirm that the proposed architecture offers a scalable, robust, and energy-efficient solution capable of advancing EV charging infrastructure and supporting sustainable transportation.

The main objective of this study is to evaluate the performance of a photovoltaic (PV) system under real-world conditions by analyzing three key climatic variables on a monthly scale: insolation, average daily temperature, and photovoltaic power output. Insolation, defined as the average daily sunshine duration, is a critical parameter for estimating the solar energy potential in the Ghardaïa region, which is characterized by a desert climate. Average daily temperature directly influences the efficiency of PV panels, as elevated temperatures tend to reduce their performance. Photovoltaic power output, expressed in kWh/m²/day, is calculated based on solar radiation, providing a measure of actual energy generation under prevailing climate conditions. The analysis of these three climatic parameters offers valuable insights into seasonal variations and their impact on solar energy production in the Ghardaïa region. To optimize PV system performance, the study emphasizes the importance of accurate system design supported by advanced numerical methods. We extend the modeling from individual solar cells to complete PV modules and arrays, accurately reproducing their electrical characteristics. Simulations are performed in MATLAB/Simulink to validate the proposed model, which is based on an enhanced two-diode representation that reflects realistic operating conditions.

A grounding system is an essential electrical safety mechanism designed to protect humans and equipment from disturbances such as lightning-induced surge currents or short circuits. It operates by channeling excess current into the ground through grounding electrodes, thereby reducing the risk of damage and hazards. High grounding resistance can compromise the dissipation of fault currents and overvoltages, leading to safety risks. This study focuses on reducing grounding resistance through chemical soil treatment using bentonite combined with a mixture of magnesium sulfate (MgSO₄) and palm shell charcoal. The optimal composition consists of 10% bentonite, 10% native soil, and 80% of the material mixture. Experiments were conducted at electrode depths of 30 cm, 60 cm, 90 cm, and 110 cm. Results showed that the initial resistance of 312.5 Ω at 30 cm depth decreased to 86.1 Ω, and at 110 cm depth, resistance decreased from 186.5 Ω to 53.0 Ω. The average reduction reached 77.4%, indicating that this material combination is highly effective in lowering grounding resistance and improving system performance.

The meerkat optimization algorithm (MOA) is used in this study to suggest an effective multi-objective optimization framework for the best location and dimensions of electric vehicle charging stations (EVCSs) in radial distribution systems (RDS). The performance of the system in terms of power loss and voltage stability is significantly affected the growing prevalence of EV loads. To reduce the real power losses and average voltage deviation index (AVDI) while improving the voltage stability index (VSI), a multi-objective function was developed. The IEEE 69-bus system is subjected to various loading conditions using the recommended MOA, which is distinguished by its balanced exploration-exploitation process and parameter-free structure. In comparison with the basic and current methodologies, simulation findings show that the recommended approach improves the voltage profile, decreases power losses, and enhances the VSI. The advantages of the MOA in terms of convergence time, solution quality, and resilience were confirmed by a comparison with the HBA, TLBO, ALO, and FPA. The results confirm that the suggested approach is effective for modern EV-integrated distribution networks.

The growing dependence on limited fossil fuels and their environmental impact drive the adoption of renewable energy, with photovoltaics (PV) being a leading option. However, PV performance often declines due to elevated operating temperatures and surface fouling, especially in tropical climates, leading to reduced efficiency. To address this, coating materials with dual functionalities of cooling and self-cleaning are needed. This study investigates banana leaf wax as a natural coating to enhance PV performance. The wax was extracted using n-hexane, applied via spray-coating, and characterized through light transmittance tests, scanning electron microscope (SEM) imaging, water contact angle (WCA), adhesion analysis, and field trials on PV modules. The wax demonstrated an average WCA of 127°, with a microcrystalline structure supporting hydrophobic and self-cleaning properties. Field implementation showed that a 9 μm wax layer reduced PV module temperature by approximately 5 °C and increased output power by 15-20% under high irradiance (G ≈1200 W/m²). The cooling effect proved more significant than transmission losses, confirming the potential of banana leaf wax as an effective tropical PV coating. Nevertheless, further studies are required to optimize thickness, strengthen adhesion through hybrid formulations, and integrate the material into advanced optoelectronic coatings for sustainable efficiency improvements.

Digital transformation plays a critical role in strengthening disaster management systems, particularly in disaster-prone countries such as Indonesia. Despite the availability of several government-led digital platforms, limited systems integrate volunteer coordination, health workforce mapping, and logistics tracking within a unified framework. This study aimed to develop and evaluate a web-based information system designed to empower disaster volunteers by integrating volunteer profiling, healthcare human resource availability, logistics documentation, and public education features. A mixed-methods descriptive analytical design was employed. Qualitative data were collected through in-depth interviews to identify system requirements and operational challenges, while quantitative data were obtained from structured questionnaires completed by 71 of 75 health-background from TAGANA Rajawali Indonesia Foundation members and at least one disaster respon experience. Descriptive non-parametric analysis informed system design and feature prioritization. Results showed that 100% of respondents supported the development of a digital coordination platform, 94.7% preferred WhatsApp integration for communication, and 86.7% were willing to contribute as digital resource persons for public education. The developed system integrates real-time manpower mapping, logistics tracking, donation management, multimedia documentation, and reporting dashboards. This model addresses a critical gap in volunteer-centered digital disaster management and strengthens community-based preparedness by improving coordination efficiency, transparency, and public health resilience.

Water quality monitoring is vital for protecting aquatic ecosystems and ensuring sustainable water resource management. Traditional manual sampling methods are often costly, time-consuming, and unsuitable for real-time assessment. This study presents a newly designed solar-powered IoT-based water quality monitoring system for remote and continuous data collection. The system utilizes an ESP32 microcontroller integrated with pH, temperature, and total dissolved solids (TDS) sensors, powered by a 10W solar panel. Data is transmitted to a cloud-based platform wirelessly, enabling remote access and visualization via a mobile app. Performance evaluation included descriptive statistics and one-way ANOVA across four sampling sites. ANOVA results showed statistically significant differences (p < 0.05) in water quality parameters among locations, confirming the system’s sensitivity. Sensor accuracy was validated against standard meters, revealing mean relative errors below 5% for pH and TDS. The system reliably provides real-time, accurate data, supporting proactive water quality management. Integrating IoT with renewable energy offers a cost-effective, scalable, and energy-efficient solution for environmental monitoring in remote or resource-limited areas.

In-hospital cardiac arrest in intensive care remains frequent (often cited incidence roughly 0.5%-7.8% of admissions), while causes differ in what staff and equipment must be ready. We ask whether vital-sign trajectories from a standard EHR can classify which of three cardiac-related mechanisms is most salient arrhythmia, acute myocardial infarction (AMI), or respiratory failure or hypoxia so ICU resources can be aligned with risk. Using MIMIC-IV, we extracted diagnoses and charted vitals in the 12 hours before the index event, applied cleaning, aggregation, label encoding, sequence padding, and class balancing (3,000 cases per class), then trained and compared eXtreme gradient boosting (XGBoost), random forest (RF), support vector machine (SVM), and logistic regression (LR) with 5-fold cross-validation on an 80/20 split. XGBoost performed best (about 93% accuracy; sensitivity 89.15%; specificity 90.43%; AUC-ROC 0.94). Feature importance highlighted heart rate, oxygen saturation, and blood pressure patterns consistent with bedside monitoring practice. The study supports mechanism-oriented triage labels derived from widely recorded vitals, as a complement to generic early warning scores, for prioritizing telemetry, respiratory support, and cardiology pathways. External validation and prospective evaluation are needed before deployment.

Lightweight parallel feedback network based on CRL with policy transfer and enhancement for image super-resolution

10.11591/ijict.v15i3.pp944-954
S V R Manimala , T Kavitha
Image super-resolution (SR) is essential in applications such as surveillance, medical imaging, and remote sensing, but existing deep learning (DL) models often require high computational resources and struggle to recover fine details in lightweight architectures. Although feedback and attention based methods have shown improvements, they still lack an effective combination of efficient feature refinement, edge enhancement, and low parameter complexity. To address this gap, we propose a lightweight parallel feedback network (LPFN) that combines three key components: a feedback block for repeated feature refinement, a dispersion-aware attention residual block (DARB) for highlighting important spatial and channel details, and EdgeNet for edge sharpening for sharper boundaries. These components are supported by curriculum reinforcement learning (CRL), an adaptive training strategy that gradually improves the model’s learning behavior. Instead of relying on a fixed loss function, LPFN uses a dynamically learned global feedback loss to refine reconstruction quality at each stage. Experiments on DIV2K and Flickr2K show that LPFN achieves higher PSNR and SSIMscores while keeping the model lightweight and efficient. This study emphasizes an effective lightweight feedback framework, an enhanced attention and edge-refinement mechanism, and an adaptive learning strategy that improves both accuracy and stability under different degradation conditions.

Advanced materials for crosstalk and power optimization in TSV-enabled 3D ICs

10.11591/ijict.v15i3.pp1143-1153
Tappeta Chinna Sanjeeva Rayudu , Merrin Prasanna Nagadasari
The continued scaling of semiconductor devices has exposed the limitations of traditional two-dimensional (2D) integrated circuit architectures. To address performance bottlenecks and interconnect constraints, the industry is increasingly adopting three-dimensional (3D) integration technologies. through-silicon vias (TSVs) are a fundamental enabler of this advancement, facilitating vertical signal transmission between stacked silicon layers. Despite their benefits, TSVs face critical challenges related to crosstalk, power dissipation, and signal delay issues that are especially pronounced in dense via arrays. This research explores the use of multi-walled carbon nanotube (MWCNT) based TSVs insulated with different dielectric liners, including silicon dioxide (SiO₂), PPC, polyimide, and benzocyclobutene (BCB). HSPICE simulations are used to evaluate crosstalk noise, power dissipation, power delay product (PDP), and energy delay product (EDP) across varying TSV pitches. Among the materials studied, BCB demonstrates the most promising results. Specifically, MWCNT TSVs with BCB at a 10,000 μm pitch achieve up to 58% reduction in functional crosstalk, 75% in dynamic crosstalk, 78% in power dissipation, and a 52% improvement in PDP compared to single-walled CNT (SWCNT) based TSVs. These findings confirm the suitability of combining MWCNT cores with low-k BCB liners for enhancing performance, energy efficiency, and signal reliability in advanced 3D integrated circuits.
