Optimized viewport‐adaptive 360‐degree video streaming
CAAI Transactions on Intelligence Technology, 2021 Because of the rapid growth of head‐mounted displays and 5G networking deployment, 360‐degree video has become increasingly popular. To generate the real experience of a virtual environment, 360‐degree videos require an ultrahigh resolution and frame ...

Soft Skins With Reversible Thickness Morphing: Materials, Mechanisms, and Applications
Advanced Materials, EarlyView.Evolution of electronic skin (e‐skin) technologies toward adaptive, multifunctional soft skins. Phase I highlights early rigid and discrete sensory interfaces. Phase II shows the transition toward flexible, stretchable, and large‐area e‐skin. Phase III captures the emergence of computational e‐skin.

An Algebraic Invariant for Substitution Tiling Systems
Geometriae Dedicata, 1998 We consider tilings of Euclidean spaces by polygons or polyhedra, in particular, tilings made by a substitution process, such as the Penrose tilings of the plane. We define an isomorphism invariant related to a subgroup of rotations and compute it for various examples. We also extend our analysis to more general dynamical systems.

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 ...

MAXIMAL EQUICONTINUOUS FACTORS AND COHOMOLOGY FOR TILING SPACES [PDF]
, 2012 International audienceWe study the homomorphism induced on cohomology by the maximal equicontinuous factor map of a tiling space. We will see that this map is injective in degree one and has torsion free cokernel.

On the Behavior of Tile Assembly System at High Temperatures [PDF]
Computability, 2012 Behavior of Winfree's tile assembly system (TAS) at high temperatures is investigated in combination with integer programming of a specific form called threshold programming. First, we propose a way to build bridges from the Boolean satisfiability problem (SAT) to threshold programming, and further to TAS's behavior, in order to prove the NP-hardness ...

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,

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.

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.
