Interaction of perceptual grouping and crossmodal temporal capture in tactile apparent-motion [PDF]

, 2011
Previous studies have shown that in tasks requiring participants to report the direction of apparent motion, task-irrelevant mono-beeps can "capture'' visual motion perception when the beeps occur temporally close to the visual stimuli. However, the

When Cubic is Not Isotropic: Phonon–Exciton Decoupling in CuInSnS4 Single Crystals

Advanced Optical Materials, EarlyView.
A cubic CuInSnS4 crystal does not fully play by cubic rules. While phonons follow the average iso‐tropic lattice symmetry, the disorder‐localized excitons break away, showing strong, and reproduci‐ble polarization‐dependent emission. This work shows how intrinsic cation disorder can turn a mac‐roscopically cubic material into a source of hidden ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

Advanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...

AN EFFICIENT BOUNDARY FITTED NON-HYDROSTATIC MODEL FOR FREE-SURFACE FLOWS [PDF]

Journal of Engineering Science and Technology, 2007
A boundary fitted non-hydrostatic finite volume model is presented to simulate two dimensional vertical free surface flows effectively deploying only 2-4 vertical layers. The algorithm is based on a projection method which results in a block tri-diagonal

Soft Robotic Snake with Tunable Undulatory Gait for Efficient Underwater Locomotion

Advanced Robotics Research, EarlyView.
This study designs an underwater soft snake robot using 3D‐printed soft actuators, controlled by specific signals to generate sinusoidal undulation. Results show a positive correlation between speed and swing amplitude, with optimal performance at 2/3π phase offset, PLA tail, 1.2 voltage growth rate, and 6s undulation period achieving a maximum speed ...

Non-Sinusoidal Wall Oscillation for Drag Reduction

, 2012
The drag reducing properties of wall flows under non-sinusoidal oscillations are analyzed in the present work. The dependency of the drag reduction rate, R, and of the power spent to move the walls, Pin, with respect the shape of the wall motion are ...

Interactions between luminance and colour signals : effects on shape

, 2013
This research was supported by the Engineering and Physical Sciences Research Council (EPSRC).Although luminance and color are thought to be processed independently at early stages of visual processing, there is evidence that they interact at later ...

Multidirectional Motion Strategy of Miniature Water Surface Robot Actuated by Single Exciter

Advanced Robotics Research, EarlyView.
A novel multidirectional motion strategy on the water surface based on a single exciter is proposed, and a single‐exciter single‐plate module is developed for actuation. The driving forces generation mechanism of the module is revealed from the perspective of the asymmetric surface wave field.
