A computational model for tiling recognizable two-dimensional languages [PDF]
, 2009 Tiling systems are a well accepted model to define recognizable two-dimensional languages but they are not an effective device for recognition unless a scanning strategy for the pictures is fixed.

An AI‐Enabled All‐In‐One Visual, Proximity, and Tactile Perception Multimodal Sensor
Advanced Robotics Research, EarlyView.Targeting integrated multimodal perception of robots, an AI‐enabled all‐in‐one multimodal sensor is proposed. This sensor is capable of perceiving three types of modalities, including vision, proximity, and tactility. By toggling an ultraviolet light and adjusting the camera focus, it switches smoothly between multiple perceptual modalities, enabling ...

Fractal Tilings from Iterated Function Systems [PDF]
Discrete & Computational Geometry, 2014 Iterated function systems (IFS) introduced in 1981 by \textit{J. E. Hutchinson} in his famous paper [``Fractals and self-similarity'', Indiana Univ. Math. J. 30, 713--747 (1981; Zbl 0598.28011)], are the main generators of fractals as attractors of the respective IFSs on a complete metric space.

On the Notions of Symmetry and Aperiodicity for Delone Sets [PDF]
, 2012 Baake M, Grimm U. On the Notions of Symmetry and Aperiodicity for Delone Sets. Symmetry. 2012;4(4):566-580.Non-periodic systems have become more important in recent years, both theoretically and practically. Their description via Delone sets requires the

Compliant Pneumatic Feet with Real‐Time Stiffness Adaptation for Humanoid Locomotion
Advanced Robotics Research, EarlyView.A compliant pneumatic foot with real‐time variable stiffness enables humanoid robots to adapt to changing terrains. Using onboard vision and pressure control, the foot modulates stiffness within each gait cycle, reducing impact forces and improving balance. The design, cast in soft silicone with embedded air chambers and Kevlar wrapping, offers durable,

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
Advanced Robotics Research, EarlyView.We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Cohomology of tiling spaces: beyond primitive substitutions [PDF]
, 2016 This thesis explores the combinatorial and topological properties of tiling spaces associated to 1-dimensional symbolic systems of aperiodic type and their associated algebraic invariants.
