Characteristics of Slamming Pressure and Force for Trimaran Hull

Journal of Marine Science and Engineering, 2021
In this paper, the characteristics of the impact pressure and force of a trimaran section was studied by Computational Fluid Dynamics (CFD). The time domain features of the slamming pressure or force showed a strong correlation with the penetration depth

Numerical simulation on characteristics of wave forces on an incompletely submerged horizontal circular cylinder

Shui kexue jinzhan, 2019
This study investigated the wave forces on an incompletely submerged horizontal circular cylinder under large-amplitude wave action using a viscous fluid numerical wave tank model based on the finite volume method. By analysing the characteristics of the

MD-SLAM: Multi-cue Direct SLAM

2022 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS), 2022
Simultaneous Localization and Mapping (SLAM) systems are fundamental building blocks for any autonomous robot navigating in unknown environments. The SLAM implementation heavily depends on the sensor modality employed on the mobile platform. For this reason, assumptions on the scene's structure are often made to maximize estimation accuracy.

The SLAM Toolkit [PDF]

, 2001
The SLAM toolkit checks safety properties of software without the need for user-supplied annotations or abstractions. Given a safety property to check on a C program P, the SLAM process [4] iteratively refines a boolean program abstraction of P using three tools: - C2bp, a predicate abstraction tool that abstracts P into a boolean program BP(P,E)

Dynamic response of high-speed craft bottom panels subjected to slamming loadings

Curved and Layered Structures, 2023
The inelastic deformation of a 30 m high-speed craft (HSC) subjected to slamming pressure is the main topic of this research. In this work, the commercial software package ABAQUS FEA is used to predict the structural behavior, especially in the hull area

NR-SLAM: Nonrigid Monocular SLAM

IEEE Transactions on Robotics
In this paper we present NR-SLAM, a novel non-rigid monocular SLAM system founded on the combination of a Dynamic Deformation Graph with a Visco-Elastic deformation model. The former enables our system to represent the dynamics of the deforming environment as the camera explores, while the later allows us to model general deformations in a simple way ...

Comparison of experimental and numerical sloshing loads in partially filled tanks [PDF]

, 2009
Sloshing phenomenon consists in the movement of liquids inside partially filled tanks, whichgenerates dynamic loads on the tank structure. Resulting impact pressures are of great importance in assessingstructural strength, and their correct evaluation ...
