Towards Cross-Modal Point Cloud Retrieval for Indoor Scenes

Cross-modal retrieval, as an important emerging foundational information retrieval task, benefits from recent advances in multimodal technologies. However, current cross-modal retrieval methods mainly focus on the interaction between textual information and 2D images, lacking research on 3D data, especially point clouds at scene level,...

Mechanistic Investigation of Vertical Sweep Efficiency in Miscible CO2-Water- Coinjection for EOR and CCUS

The main objective of this study is to understand the vertical sweep efficiency with miscible CO2-water-coinjection as a secondary recovery method, from multiple perspectives: phase behavior, total relative mobility, fluid densities/viscosities, the driving forces and consequent phase distributions etc. We also seek to provide insights into...

AR-Assisted Assembly in Self-Build Construction with Discrete Components

The prevailing issue of low housing supply is caused in part by a lack of skilled construction workers. If unskilled residents were adequately equipped, they could potentially address this issue, expanding and adapting their homes without professional builders and designers. This research proposes the use of discrete components to build on...

A molecular dynamics study of N-A-S-H gel with various Si/Al ratios

The understanding of sodium aluminosilicate hydrate (N-A-S-H) gel is still limited due to its complex and amorphous structure. Recently, molecular dynamics simulation has provided a unique opportunity to better understand the structure of N-A-S-H gel from nanoscale. In this work, the N-A-S-H gel structure was obtained by simulating the...

The application model of 3D cadastre in practical registration for real estate in China

Since the introduction of the concept of 3D cadastre, a great many of significant research results have been done. To promote the development of 3D cadatre, 3D cadastre working group sponsored by International Federation Surveyors (FIG) commissions 3 and 7 was organized by Delft University of Technology in 2001. This working group provides a...

Designing a Title Certificate for the Chinese 3D Cadastre

When the land use pattern changes from an extensive way to an intensive way, the development of 3D land-use has become reality. Due to the vertical heterogeneity of property rights, establishment of 3D cadastre is imperative. Meanwhile, registration and certification of the property rights have become important approaches to serve public and...

Logical Design and Implementation of the Data Model for 3D Cadastre in China

The establishment of 3D cadastre is imperative and needs support from legal, organizational and technological aspects. In Shenzhen, China, establishment of 3D cadastre has achievedgreat progress. The joint register mechanism was employedfirstly in Shenzhen, and related research is going on, including definitions, visualization and topological...
