Baseline direction measurement for active optical imaging systems

We propose a closed-form method for measuring the baseline direction in active optical imaging systems, including projector-camera and laser-emitter imaging configurations. The method uses two planar homographies induced by observing a planar target at different system-to-plane d...

A Specific Geometric Relationship Method for Fault Diagnosis and Fault Tolerant Control in ECAS

ABSTRACT The research on the control and health management of electronically—controlled air suspension is an important branch in the field of intelligent chassis. Aiming at the problem that actuator faults cannot be detected quickly and intuitively during the vehicle height adjus...

Non-linear drivers of urban-to-rural mobility in China’s Greater Bay Area: insights from mobile phone big data

Persistent urban–rural disparities hinder global sustainable development goals, while rural revitalization plays a pivotal role in advancing these objectives. High-frequency urban-to-rural mobility strengthens functional linkages between cities and rural areas by facilitating rec...

Learning instance-level semantic Gaussian representations for occlusion-aware urban scene reconstruction from UAV imagery

UAV-based earth observation provides an efficient and flexible means for detailed urban geospatial modeling and digital twin construction. However, in complex urban environments, foreground occlusions caused by trees, vegetation, and other clutter frequently lead to incomplete st...

Financing Innovation, Extracting Rent: Real-Estate Financialization and the Limits of Barcelona’s 22@BCN Innovation District

This study examines 22@Barcelona (22@BCN), a widely cited case in the development of innovation districts. Initially conceived as a means of transforming Poblenou from a post-industrial area into a knowledge-economy hub, 22@BCN also formed part of Barcelona’s broader trajectory o...

Perchloric acid (HClO 4 ) drives atmospheric new particle formation enhanced by dimethylamine, ammonia and sulfuric acid: mechanisms and implications

Abstract. Recent studies have revealed observations of atmospheric perchloric acid (HClO4, PA) in the Arctic. There are few studies of PA forming aerosol particles in coastal marine regions. We use quantum chemical calculations and Atmospheric Clusters Dynamic Code (ACDC) to comp...

Generative geospatial modelling with geometric algebra

Abstract The integration of data-driven and knowledge-driven approaches in generative geospatial modelling (GGM) is often hindered by their mathematical incompatibilities. Here, we propose a geometric algebra (GA)-based framework that employs a unified multi-vector representation...
