The limited autonomy of flight has long been considered a significant constraint in drone systems. In the context of drone inspections of power lines, this study focuses on a drone equipped with a coil designed for autonomous battery charging. Positioned atop the drone is a charging coil, and on the upper surface, there is an upward-facing camera with a restricted field-of-view (FOV), serving the crucial role of aligning the drone with power lines. This research introduces a wireless power transfer strategy to facilitate the self-charging process of the drone while maintaining its position beneath power lines. To enable the drone's autonomous approach to power lines, a method is devised to guide the drone from below. As the drone approaches the power lines, it monitors the current induced by these lines and gradually adjusts its altitude until a sufficiently high induced current is achieved. The proposed approach ensures safety, as the drone avoids direct contact with high-voltage power lines, setting it apart from other existing methods that require such contact. To the best of our knowledge, this study offers a novel approach to precisely controlling drone movements, and establishing reliable wireless power transfer from power lines. The effectiveness of the developed wireless transfer strategy has been verified through MATLAB simulations. © 2024 IEEE.

Extended periods of sitting in corporate environments have been known to lead to a lot of health concerns, including lower back aches and neck strain. This sedentary lifestyle not only put employees' well-being at risk but also hinders overall work efficiency and job satisfaction. These detrimental effects of prolonged sitting necessitate an intervention to mitigate these issues and enhance workplace health. The proposed application seamlessly integrates into the work environment by using camera input from the device's webcam and MediaPipe Pose for posture detection and correction. It delivers personalized prompts and reminders, fostering user awareness and enabling self-improvement. Through this comprehensive approach, which includes promoting breaks to address the detrimental effects of prolonged sitting, this solution creates a healthier and more productive workplace. Moreover, the application prioritizes user privacy by performing all computations locally on the user's device. This on-device processing not only safeguards privacy but also allows for uninterrupted operation even in the absence of an internet connection. © 2024 IEEE.

Respiratory diseases are the leading morbidity in the world. The correct and speedy diagnostic tools are crucially required for efficient management. This paper examines the power of vocal biomarkers in correctly diagnosing respiratory conditions using advanced machine-learning techniques. We have utilized a benchmark dataset and used sophisticated preprocessing techniques to reduce noise and improve the quality of the signals. We extracted diverse numerical features including time domain, statistical, chroma, harmonic, percussive, entropy, peak-based, and rhythm. All these features were compiled structurally in a data frame for further analysis. We adopted a two-step strategy to deal with class imbalance. First, data augmentation techniques such as time stretch, pitch shift, and random crop were applied before feature extraction to increase the sample size;still, class imbalance persisted. Hence, at the later stage of feature extraction, we introduced a hybrid approach that combines random oversampling and undersampling techniques to make classes balanced, thus ensuring accuracy by measuring and adjusting class weights. The performance was evaluated against several classification traditional algorithms and neural networks. All classifiers and neural network architectures returned outstanding results;the ExtraTrees classifier stood out at 99.47%. This paper focuses on the effectiveness of using vocal biomarkers and machine learning models for the non-invasive but accurate diagnosis of respiratory conditions and opens up ways for further smart healthcare solutions. ©2024 IEEE.

This article presents a novel transformer-less single-stage buck-boost inverter (SSBBI) utilizing coupled inductors and its dual-mode time-sharing control method. The leakage current can be completely suppressed by connecting the neutral of the electrolytic capacitors to the common ground of the power grid. Besides, only one MOSFET operates at high-frequency in Buck and Boost mode. As a result, in theory, high conversion efficiency can be guaranteed for the proposed inverter. Moreover, compared with conventional Aalborg inverters, the number of switches, diodes, and inductors is further reduced to reduce cost and increase power density. In addition, the operating principle based on equivalent circuits and the control strategy of the proposed inverter are given in this article. As a proof of concept, the simulation results based on PSIM of the proposed SSBBI with different input voltages and output powers and a 110 V power grid are provided. © 2024 IEEE.

This paper proposes a novel single-stage single-phase transformerless topology based on a buck-boost converter for grid-connected photovoltaic (PV) inverters. The proposed inverter has a wide input voltage range, low total harmonic distortion of current, and effective suppression of common-mode leakage current. The single-input structure ensures that it does not suffer from energy imbalance problems. The new inverter utilizes dead beat control and refines the method of controlling the inverter when the input energy is insufficient. The simulation results verify that the proposed grid-connected PV inverter maintains high grid-connected power quality both during normal operation under conventional conditions and when operating under discontinuous conduction mode (DCM) during energy insufficiency. The simulation models the operating mode of the inverter under abnormal environments, such as load changes and grid voltage transients, which proves that the proposed inverter under dead beat control has a better dynamic performance. © 2024 IEEE.

The low organic soils present in the Kari lands of the Kuttanad region bear significant importance in the design of shallow foundations due to their inherently poor engineering characteristics and usually require stabilization. In recent years, sustainable stabilization practices that rely on waste-derived products are gaining attention. The augmentation of the shear parameters of soils with low organic content by the inclusion of sustainable crustacean biopolymers is a novel method owing to their contribution to waste management. The current study aims to understand the consolidated undrained behavior of chitosan-treated low-organic soils relying on triaxial tests. The tests are performed on samples mixed with 1% and 2% of the biopolymers. The effect of the curing period and confining pressure on these samples are evaluated by conducting consolidated undrained triaxial tests at confining pressures of 50, 100, and 150 kPa to evaluate the efficiency of treatment. The microstructural improvement is confirmed by conducting a scanning electron microscope. The chitosan treatment exhibits a considerable enhancement in effective cohesion by a factor of 1.88 for 60-day cured 2% amended samples owing to the networking of soil particles by fiber formations, as revealed from SEM images. The presence of the fibers contributes to the increase in the angle of internal friction with the curing period. Considering the range of effective cohesion (96.2-142.9 kPa) and effective angle of internal friction (9.4°-20.5°) attained for chitosan-stabilized soil samples, these materials can serve as excellent foundation materials. © ASCE.

To address the problem of insufficient intra-modal feature extraction and inter-modal interaction information fusion in current multimodal sentiment analysis, a multi-feature fusion multimodal sentiment analysis model based on cross-attention mechanism is proposed. The model first uses subnetworks and self-attention mechanism to obtain important features of multiple modalities such as text, audio, and video. Then, it calculates the correlation between modalities through cross-modal cross-attention mechanism to achieve the interaction and fusion of multimodal information. After that, soft attention mechanism is used to assign attention weights to each modality feature. Finally, the modalities features are spliced to output the final sentiment classification result. The experimental results show that compared with the benchmark model on the public datasets CH-SIMS and CMU-MOSEI, this model has certain improvements in two-class accuracy, three-class accuracy, and F1 value. © 2024 IEEE.

If adversaries were to obtain quantum computers in the future, their massive computing power would likely break existing security schemes. Since security is a continuous process, more substantial security schemes must be developed. Current PQC schemes primarily focus on data security or key exchange, and further improvement towards enhanced PQC primitives is required. Our proposal in this research is an innovative paradigm for PQC-focused cloud data security. The proposed HEDT approach achieves encryption and decryption with significantly lower latency (20% improvement) and higher reliability than AES, DES, and RSA, as demonstrated through experimental results. Furthermore, ECSIDH, a hybrid key exchange mechanism combining SIDH and ECDH, improves security strength by 50% while maintaining computational costs within 1.13x of SIDH. Compared to individual key exchange schemes like SIDH, ECSIDH offers superior security as a PQC candidate. These results confirm the robustness and efficiency of the proposed framework in ensuring secure data outsourcing and key exchange in cloud environments. © 2025 Slovene Society Informatika.
