The high rate of increasing latency-sensitive Internet of Things (IoT) application and smart city systems has revealed the constraints of the traditional task scheduling algorithms in the fog-cloud systems, particularly in the situations were dynamically varying workloads and the type of resources may be changed. This paper presents a better Adaptive Task Scheduling system by extending Deep Reinforcement Learning (DRL) based RTAMOTS model and adding deadline feasibility, adaptive multi-objective reward shaping, action masking, and fairness-based scheduling to the model. The suggested structure is superior to the existing DRL schedulers since it takes task viability into account prior to scheduling to optimize the Service Level Agreement (SLA) compliance, whereas a dynamically weighted reward functionalities exchange deadline satisfaction, energy usage, and queue stability in training. Action masking eliminates infeasible scheduling decisions, and priority aging algorithm prevents task starvation, such that resources are fairly exploited on the fog and cloud machine. The large-scale simulations experiments like the comparative analysis with several state-of-the-art scheduling models suggest that the improved RTAMOTS is far more makespan- and energy-efficient and more equitable and compliant with SLA. These results indicate that the proposed solution possesses a scalable and effective solution to real-time tasks scheduling in fog-cloud computing systems.

This paper introduces a prediction-based interference algorithm in a multi-UAV scenario to calculate and apply the minimum interference-free flight time. The algorithm summarizes the UAV dynamic equation into kinematic equations using a low-level controller. Neighboring UAVs exchange their predicted trajectories at each sampling time to predict interferences. Then, the distributed nonlinear predictor under the interference resolution law and strategy predicts the possible control variables for each UAV and calculates the minimum required travel time. Subsequently, a collision avoidance system is designed based on a predictive distributed controller for tracking, in which anti-collision constraints are defined according to the International Civil Aviation Organization (ICAO) priority rights. To reduce the computational burden, the predictive distributed controller is formulated as a quadratic integer programming optimization problem. The results show that the proposal can resolve conflicts in real time and in the presence of a crowded airspace, while there is no interference and secondary interference. The proposed algorithms were simulated using MATLAB software and the estimated time was compared with the flight time, which showed the favorable performance of the proposed algorithm. Also, to verify the effectiveness of the interference solution, the deviation of the aircraft flight path due to maneuvers and the increase in the path length were shown, and the value of the collision avoidance system was more accurate compared to other aircraft with less efficiency.

This study aims to enhance the detection and characterisation of anomalies in manufactured parts by integrating machine learning (ML) with resonance frequency spectra data. A key contribution of this work is the development of a novel Impulse Excitation Technique (IET)-based method that effectively evaluates material health and identifies subtle defects by leveraging numerous mathematical and physical metrics as input features. Three machine learning models - Random Forest (RF), K-Nearest Neighbor (KNN), and Multi-layer Perceptron (MLP) - were systematically compared to determine the most effective method for classifying defects, specifically focusing on healthy, cracked, and dimensionally deviated samples. Among these, the MLP model demonstrated the highest performance, achieving Receiver Operating Characteristic (ROC) values of 0.963, 0.901, and 0.942 for each class, respectively. Additionally, SHAP (SHapley Additive exPlanations) analysis showed anomalies were sensitive to specific resonance frequency metrics, improving prediction accuracy. Cracked samples exhibited slight peak broadening and negative peak shifts, while dimensionally deviated samples showed positive and negative shifts and missing peaks. Dimensional deviations were more pronounced than cracks, making them easier to identify and enhancing predictive accuracy.
Given the increasing need for interactive human-computer applications, the field of employing machine learning algorithms to discern emotions from speech has seen a substantial surge in interest. While emotion recognition systems have made substantial progress in languages like German, English, Spanish, Dutch, and Danish, the availability of comprehensive datasets for the Kurdish language remains notably limited. This paper addresses this gap by focusing on emotion recognition in Sorani Kurdish dialect speech data, which was carefully gathered from openly available videos from the YouTube platform and categorized into four clear supposed emotions: neutral, sadness, happiness, and anger. The study applied both natural Mel Spectrogram and Mel-Frequency Cepstral Coefficient (MFCC) features for various spectrals, followed by the classification models K-Nearest Neighbor (KNN), Multi-Layer Perceptron (MLP), and Support Vector Machine (SVM) to evaluate the results. By closely examining and contrasting the results of using several methods for feature extraction, it was found that SVM obtained a higher accuracy, reaching as much as 85.57%. This is so much more than the first Kurdish emotion classification technique for the recognition of the emotion of the words.
