Deformation Analysis of Deep Foundation Pits Based on Fluid–Structure Interaction
Advances in Civil Engineering, Volume 2026, Issue 1, 2026.In foundation pit engineering design, the seepage‐induced impact of groundwater is often oversimplified when calculating the deformation of the retaining structure and the surrounding soil caused by excavation. Moreover, the coupled interaction between groundwater and soil is neglected, causing simulated conditions to deviate from actual site ...

Stress‐Dependent Soil Water Characteristic Curves of Compacted Sand–Gypsum Mixtures
Journal of Engineering, Volume 2026, Issue 1, 2026.The presence of calcium sulfate (CaSO4) impacts soil structure, bonding, pore size distribution, and water‐holding characteristics, altering both compaction characteristics and soil water characteristic curves (SWCC). In this study, compacted sand with different amounts of gypsum (0–60%) were tested under controlled stresses, focusing on assessing the ...

A Review of Automatic Identification System Approaches for Maritime Cyber Security
Security and Communication Networks, Volume 2026, Issue 1, 2026.The Automatic Identification System (AIS) has become a cornerstone of modern maritime navigation, traffic management, and situational awareness, enabling continuous exchange of vessel identity, position, speed, and voyage‐related information across global maritime networks. While AIS significantly enhances navigational safety and operational efficiency,

Finite Odometer Factors Of Rank One Group Actions
In this paper, we give explicit conditions characterizing the Følner rank one group actions that factor onto a finite odometer; those that factor onto an arbitrary, but specified odometer, and those that factor onto an unspecified odometer.

Ammonia Observations Over Large North American Cities
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.Abstract Ammonia (NH3) contributes to fine particle formation and nitrogen deposition. Observations of NH3 are limited compared to other major anthropogenic pollutants. Here, we explore the relationships between NH3 and other urban pollutants using measurements collected from the NASA DC‐8 aircraft during the Atmospheric Emissions and Reactions ...

Mobile Robot Localization Based on Vision and Multisensor
Journal of Robotics, 2020 To deal with the low accuracy of positioning for mobile robots when only using visual sensors and an IMU, a method based on tight coupling and nonlinear optimization is proposed to obtain a high-precision visual positioning scheme by combining measured ...
