A systematic review of multimodal emotion and sentiment analysis based agentic AI frameworks in educational systems

The use of agentic Artificial Intelligence (AI) techniques in educational settings has significantly transformed teaching methods, leading to the development of an intelligent system that can recognise and respond to students’ emotional states in real-time. Since multimodal Emoti...

Evaluation of energy performance in buildings with flexible and semi-transparent photovoltaic integration

This paper examines how building envelope material and Building Integrated photovoltaic system (BIPV) integration affects the energy performance of a prototype office building which is located in a semi-arid and warm climate i.e. Peshawar Pakitan. In this study, a simplified sing...

Quad port MIMO antenna design for WLAN and N78 application using regression machine learning validation

This paper presents the design and analysis of a compact four-port MIMO antenna intended for 5G communication systems, specifically targeting the n78 band (3.5 GHz) and the WLAN band (5.25 GHz). The proposed antenna has dimensions of 88.2 mm × 88.2 mm (1.03λ 0 × 1.03λ 0 ). It ach...

Bimodal Speech Emotion Recognition Using a Hybrid CNN-LSTM Architecture with Sentiment Fusion

Speech emotion recognition (SER) is a fundamental task in affective computing; however, traditional unimodal approaches often struggle to capture the complex emotional cues present in spontaneous conversational speech. Bimodal frameworks that integrate acoustic and textual inform...

How perceived virtual-idol advertising appeals shape impulsive hotel booking intention: identity-activated persuasion in Saudi hospitality

Virtual idols – digitally created influencers with programmable personas and symbolic identities – are increasingly used in hospitality marketing, yet the processes through which their perceived advertising appeals shape booking-related responses remain insufficiently understood....

Estimating the technical efficiency of offshore fisheries in Sri Lanka and evaluating the impact of digital technology

As marine resources decline rapidly, integrating digital technologies with traditional fishing practices has become essential for improving resource efficiency and achieving sustainable economic outcomes. This study estimates the technical efficiency of Sri Lanka's inboard multid...

Evaluation of Photovoltaic Module Enhancer Performance: Examining a New Factor for Cost and Energy Effectiveness

Photovoltaic (PV) enhancement technologies, including cooling systems, reflectors, and tracking mechanisms, are widely employed to improve the electrical performance of PV systems. However, the effectiveness of these technologies should be evaluated not only in terms of performan...

Is There a Best Hypergraph Neural Network? A Significance-Aware Recomputation and Statistical Audit of DHG-Bench

Deep hypergraph learning is evaluated almost entirely through leaderboards that rank methods by mean accuracy over a few random seeds, usually without significance testing. Is there a best hypergraph neural network, or does the apparent ordering reflect seed noise? We independent...
