18+ hour, 25+ min ago   (497+ words) Research on educational virtual reality (VR) has focused on learning outcomes, but less on the design strategies that create those outcomes or whether benefits are consistent across different learners. This study created user experience (UX) design guidelines for educational VR…...

19+ hour, 50+ min ago   (591+ words) Framework and runtime selection for containerized microservices are usually guided by request-level benchmarks, yet deployment-facing costs often dominate operational expenditure in Kubernetes environments. This study empirically evaluates four such infrastructure characteristics: container image size, startup time, idle resource consumption, and…...

21+ hour, 59+ min ago   (394+ words) With the rapid development of wireless communication technologies, mobile devices, and distributed systems, the scale and dynamics of Mobile Ad Hoc Networks (MANETs) are increasing, which results in increasingly stringent requirements for routing protocols. The Zone Routing Protocol (ZRP), as…...

21+ hour, 59+ min ago   (496+ words) Aspect-based sentiment analysis (ABSA) aims to identify the sentiment polarity expressed toward a specific aspect in a sentence. Existing sequential and Transformer-based methods can effectively capture contextual semantics, but they often lack explicit modeling of aspect–opinion relations. Graph-based approaches…...

1+ day, 1+ hour ago   (165+ words) This study proposes an efficient trajectory planning method for fixed-wing unmanned aerial vehicles (UAVs) based on an improved A*-guided initialization strategy for complex obstacle environments. An improved three-dimensional A* method is developed to generate smooth and collision-free global paths…...

2+ day, 16+ hour ago   (533+ words) This study proposes EQAS (Empowered Question-Answering System), a hybrid framework designed to support context-aware question-answering and intelligent feedback generation in domain-specific knowledge environments. EQAS integrates fine-tuned transformer-based models, instruction-guided large language models, domain-specific knowledge graphs, and LangChain-based vector retrieval to…...

2+ day, 16+ hour ago   (571+ words) Deep neural networks (DNNs) are widely deployed in safety-critical applications such as medical diagnosis and autonomous driving. Adversarial training (AT) is among the most effective defenses, casting robust optimization as a min–max problem over a defender-specified ℓp-ball of fixed…...

2+ day, 16+ hour ago   (415+ words) Multi-product production systems require effective coordination among production, intermediate storage, downstream processing, and customer demand, particularly under stochastic operating conditions and finite capacity. Unlike existing analytical studies that mainly examine either single-product push–pull systems or multi-product manufacturing systems separately,…...

2+ day, 16+ hour ago   (396+ words) In the field of public service data integration, government agencies are responsible for consolidating data from various industries and establishing big data platforms. Some achievements have been made in this direction, but there are still some issues related to privacy…...

2+ day, 17+ hour ago   (359+ words) Productivity evaluation in industrial software projects is still predominantly based on aggregate Function Point-to-effort ratios. Such an approach overlooks the internal structural and functional heterogeneity of software projects, potentially leading to misleading comparisons between systems characterized by similar functional sizes…...
