Early Detection of Autism Spectrum Disorder in Children Using Different Machine Learning Algorithms

Sabreen Kadhum, Mohammed Ali Tawfeeq

Pages: 47-58

PDF Full Text
Abstract

Autism spectrum disorder (ASD) is a neurological condition marked by impaired communication abilities, social detachment, and repetitive behaviors in individuals. Global health organization facing difficulties in establishing an effective ASD diagnostic system that facilitates precise analysis and early autism prediction. It is a scientific issue that necessitates resolution. This research presents an approach for the early prediction of children with ASD utilizing significant variables through machine learning (ML) methods. Three stages comprise the suggested technique. First, a 1250-case ASD dataset was identified and preprocessed. Five extremely effective traits with high Pearson correlation coefficient (PCC) are chosen from 10 chosen ASD feature dataset through its paces using five ML techniques: Naive Bayes (NB), K-Nearest Neighbor (kNN), Decision Tree(DT), Support Vector Machine (SVM), and AdaBoostM1 (ABM1). The proposed framework is assessed in the third phase utilizing five measurements such as accuracy, precision, predicting time ,recall, and F1-score, . The findings revealed that: NB and K-NN approaches exhibit superior accuracy rates of 99.2% and 97.2%, with minimal prediction times of approximately 0.3 and 0.45 seconds, correspondingly. Conversely, the DT and AdBM1 methods demonstrate a minor decline in accuracy, achieving 94.8% and 87.6%, respectively, along with increased prediction times. Nonetheless, the SVM approach exhibits the least performance, achieving an accuracy of 80.4% with prediction time of 0.84 seconds. This research aligns with several Sustainable Development Goals (SDGs), including ٍSDG3, which focuses on good health, SCG10, which addresses reducing inequalities, including those related to disability. and SCG9 by strengthening technological capabilities, particularly in scientific research

Optimization and Control of Hybrid Renewable Energy Systems: A Short Critical Review

Dalmn Yaseen Taha, Tawfeeq Wasmi Mohammed

Pages: 33-46

PDF Full Text
Abstract

The worldwide evolution towards cleaner and more sustainable energy infrastructures has fostered intense research on Hybrid Renewable Energy Systems (HRES) that combine two or more energy sources that are complementary to each other to tackle the limitations of individual renewables. This paper reviews the optimization, control, and energy management strategies used for the HRES and provides a critical short review of the same. This paper covers system classification, component modeling, classical and metaheuristic optimization techniques, AI-based energy management, and techno-economic assessment. The review also highlights key current challenges and offers directions for future research, including AI-based smart systems, hydrogen integration, digital twins, and blockchain-based energy trading.

AI-augmented networked control systems subject to network latency and packet loss

Maher Faik Esmaile, Huda Mohammed Akar, Ghassan Salem Al- Saadi

Pages: 68-76

PDF Full Text
Abstract

Networked Control Systems (NCSs) are increasingly deployed in critical infrastructure, yet their performance is often compromised by communication impairments such as time-varying delays and packet loss. These disturbances can undermine stability, reliability, and overall efficiency. To address these challenges, this study proposes an AI-augmented supervisory control framework that integrates communication metrics directly into the control strategy rather than relying solely on conventional error signals. The architecture employs machine learning classifiers—specifically K-Nearest Neighbors (KNN) and Random Forest (RF)—to assess real-time network conditions (normal, degraded, and emergency) and dynamically adjust the parameters of a core PID controller. Under degraded conditions, PID gains are attenuated to enhance robustness against latency, while in emergency scenarios, a conservative safe-mode configuration is activated to preserve plant stability under severe packet loss. Comparative analysis demonstrates that Random Forest, due to its ensemble-based design, achieves superior situational awareness, smoother mode transitions, and more reliable global stability than KNN. Moreover, RF reduces volatile parameter updates, thereby protecting physical actuators from excessive stress and extending component lifespans. The findings highlight the potential of ensemble learning approaches to enhance resilience and operational safety in delay-prone NCS environments.
