A Two-Stage Unsupervised–Supervised Machine Learning Framework for Maximum Power Point Tracking of Photovoltaic Systems

Maximum Power Point Tracking (MPPT) is essential for maximizing photovoltaic (PV) energy extraction under changing operating conditions. This paper investigates a two-stage machine-learning framework combining K-means or fuzzy C-means (FCM) clustering of irradiance–temperature co...

Thermal-economic performance assessment of heat recovery-oriented design of integrated CCHP-H₂ system; multi-objective optimization with LCA and AdaBoost decision-making

Combined cooling, heating, power systems integrated with hydrogen production (CCHP–H₂) can simultaneously supply useful outputs while improving the utilization of fuel and recoverable thermal energy. The present project proposes a methane-fueled CCHP–H₂ configuration integrating...

Current Evidence on Gene-Based and Epigenetic Therapeutic, Diagnostic, and Prognostic Strategies in Epithelial-Derived Carcinomas: A Scoping Review

Background: Epithelial-derived carcinomas exhibit genomic instability due to genetic mutation and epigenetic dysregulation. Mechanisms such as DNA methylation, histone modifications, and noncoding RNA regulation may lead to tumor progression, immune evasion, and treatment resista...

Ab Initio Investigation of the Electronic Structure and Spectroscopy of LiTe and LiTe+ Including Spin–Orbit Coupling: Prospects for Laser Cooling

Abstract The electronic structure and spectroscopic properties of neutral LiTe and ionic LiTe+ molecules are investigated using high-level ab initio calculations based on the CASSCF/MRCI + Q method, employing the aug-cc-pV5Z basis set for Li and an effective core potential for Te...

Fracture-Controlled Mechanical Behavior of Steel Fiber-Reinforced Ultra-High-Performance Concrete Incorporating Slag and Limestone Powder Under Static and Impact Loading

Ultra-high-performance concrete (UHPC) is characterized by exceptional compressive strength; however, its structural performance is primarily governed by tensile behavior, fracture resistance, and energy dissipation. This study presents a comprehensive mechanical characterization...

Sustainable development of lignin-based biodegradable coating from palm tree waste for aluminum foil applications

Abstract The environmental challenges presented by synthetic, non-biodegradable coatings used in aluminum packaging have accelerated the search for sustainable alternatives. This research aimed to develop and optimize biodegradable lignin-based coatings derived from Date Palm Emp...

A Study of Signalling Effectiveness in Entrepreneurial Opportunity Decisions

Signal effectiveness occurs when signals elicit the desired stakeholder validation, enabling entrepreneurs to gain confidence in opportunities, secure funding, and facilitate venture decision-making. Prior research has emphasised senders and signal attributes, but the receiver’s...

Curating Visual Thinking: Virtual Exhibitions in Foundation Architecture Design Education

The early design courses engage and hone students’ visual, spatial, and communicative skills so that first-year design students begin to understand composition, abstraction, hierarchy, development of process, and representation through experimental, process-driven exercises. Exhi...

Optimizing Voice-Based Feature Engineering and Machine Learning Pipelines for Early Parkinson’s Disease Detection

Most voice-based Parkinson’s disease studies evaluated a narrow set of models on fixed feature spaces, which limited generalizability and obscured feature–model synergies. Many also neglected fold-wise fitting and runtime measurement, increasing the risk of data leakage and hinde...
