Identification of Urban Functional Areas Based on the Multimodal Deep Learning Fusion of High-Resolution Remote Sensing Images and Social Perception Data

Buildings, 2022
As the basic spatial unit of urban planning and management, it is necessary to know the distribution status of urban functional areas in time. Due to the complexity of urban land use, it is difficult to identify the urban functional areas using only ...

Uncertainty assessment of spatial soil information [PDF]

, 2023
Uncertainty is present in our daily lives. It affects our decisions on what to do. The weather forecast might tell us that there is a 60% chance that it will rain: we take umbrellas. If it says that the chance of rain is only 10% we might decide to leave

Structure and information in spatial segregation [PDF]

Proceedings of the National Academy of Sciences, 2017
Significance The multiscalar structure of ethnoracial spatial segregation informs both urban policy and sociological theory, but existing methods for studying this structure have limitations. The tools developed in this paper enable flexible, multiscalar forms of analysis and visualization for spatial segregation.

A Method for 3D Building Individualization Integrating SAMPolyBuild and Multiple Spatial-Geometric Features

Sensors
Individualization of buildings is one of the key issues in the establishment of three-dimensional (3D) building models. Most existing individualization methods rely on inefficient manual separation, while deep learning approaches require extensive pre ...

Forecasting the Dialysis Burden in Japan: Validation‐Based Projections of Prevalence and Incidence Through 2050

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Japan has one of the highest dialysis prevalence rates worldwide and a shrinking, aging population. Whether dialysis burden has entered a sustained post‐peak phase or whether recent declines partly reflect pandemic‐related disruptions remains uncertain.
