4+ day, 18+ hour ago   (452+ words) Short-term particulate-matter forecasts are strongly influenced by temporal persistence, which can obscure the incremental value of meteorological covariates and seasonality. This study evaluates that incremental value using 42,823 hourly observations of PM10 and meteorological conditions from Kraków, Poland, collected during 2020–2024. Four interpretable…...

5+ day, 2+ hour ago   (503+ words) Growing urbanization and increasing traffic intensity create a need for transparent tools that support urban transport management and city logistics planning. The aim of this study is to propose an interpretable rule-based decision-support framework that transforms short-term traffic-count data into…...

5+ day, 19+ hour ago   (433+ words) Accurate prediction of tunnel vault displacement and reliable assessment of deformation risk are essential for tunnel safety management under complex geological conditions. This study develops an integrated data-driven framework combining machine-learning prediction, metaheuristic hyperparameter optimization, statistical model comparison, and uncertainty-informed…...

1+ week, 2+ day ago   (358+ words) Zn2SnO4 is a promising anode for lithium-ion batteries owing to its high theoretical capacity, yet its practical utilization is severely limited by sluggish reaction kinetics, large volume expansion, and unstable electrode/electrolyte interfaces. Here, we introduce a dimensionality-reduction strategy that simultaneously…...

1+ week, 2+ day ago   (448+ words) Network-level congestion assessment requires segment states to be aggregated across roads that differ in length, observed flow, capacity, and functional role. In data-limited settings, however, traffic agencies may only have road class, segment length, traffic flow, capacity, and average speed,…...

1+ week, 3+ day ago   (595+ words) The article is devoted to the current problem of optimizing transport flows implemented within a mechanical engineering enterprise, where the efficiency of logistics operations directly affects the productivity and competitiveness of production. Optimization of the parameters of transport flows implemented…...

1+ week, 3+ day ago   (550+ words) Spacing design for group cable bolt systems remains largely empirical and rarely considers stress interaction and displacement overlap together. This study develops a dual-index interaction framework for two representative cable bolt configurations in deep stope roofs. Mindlin’s semi-infinite body solution…...

1+ week, 6+ day ago   (433+ words) Air pollution data processing is a relevant aspect of urban-life-quality monitoring. This study relates the values of air pollutants to meteorological factors with prediction models created with multiple linear regression (MLR) in the R program. Fragmented data were obtained in…...

2+ week, 1+ day ago   (503+ words) Pavement deterioration poses substantial technical-economic burdens and brings notable social-environmental risks: degraded road surfaces increase vehicle maintenance expenditures, raise traffic accident probabilities, lower transportation operational efficiency, and produce extra carbon emissions caused by aggravated fuel consumption. Automatic pavement defect detection…...

2+ week, 2+ day ago   (452+ words) Urban Digital Twins excel at modeling physical infrastructure but remain structurally limited in capturing the qualitative, experiential dimensions of urban life—particularly sense of place, which empirical research links to civic stewardship and long-term sustainability. This study investigates whether generative…...
