Automatic Determination of Quasicrystalline Patterns from Microscopy Images
Advanced Intelligent Discovery, EarlyView.This work introduces a user‐friendly machine learning tool to automatically extract and visualize quasicrystalline tiling patterns from atomically resolved microscopy images. It uses feature clustering, nearest‐neighbor analysis, and support vector machines. The method is broadly applicable to various quasicrystalline systems and is released as part of

Optimizing 3D Bin Packing of Heterogeneous Objects Using Continuous Transformations in SE(3)
Advanced Intelligent Systems, EarlyView.This article presents a method for solving the three‐dimensional bin packing problem for heterogeneous objects using continuous rigid‐body transformations in SE(3). A heuristic optimization framework combines signed‐distance functions, neural network approximations, point‐cloud bin modeling, and physics simulation to ensure feasibility and stability ...

Ship Control in Manoeuvring Situations with Fuzzy Logic Controllers [PDF]
TransNav, 2008 In this paper, the ship control regulator in manoeuvring situation is presented. It consists of three fuzzy logic controllers. Each controller controls one of motions: turning, transverse and longitude motion of a ship.

The hydrodynamic and dynamic motion analysis of a damaged ship
, 2008 The hydrodynamic analysis and motion response of a damaged ship requires a novel generalisation of the methodsnormally applied to intact ships or other floating structures. Damaged ship statistics are used to provide likely damage scenarios.

A Two‐Stage Characterization Pipeline and Open‐Source Framework for Reproducible Tactile Sensing
Advanced Intelligent Systems, EarlyView.The same soft tactile sensor returns different numbers when embodied in different robots. This is an Embodiment Gap that no shared framework currently captures transparently. A two‐stage characterization pipeline, paired with a FAIR open‐source digital datasheet, decouples intrinsic sensor behavior from embodiment effects and condenses cross‐laboratory

On the steering motions of ships
Journal of the Society of Naval Architects of Japan, 1969 In this paper, the author introduces the nonlinear equations of steering motions of ships in calm water and indicates the solutions for these. Here, the ship motions are limited to the step responses and the periodic motions.
