Numerical Modeling of Photothermal Self‐Excited Composite Oscillators

open access: yesAdvanced 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.

Comparison of Quadratic– and Median-Based Roughness Penalties for Penalized-Likelihood Sinogram Restoration in Computed Tomography

open access: yesInternational Journal of Biomedical Imaging, 2006
We have compared the performance of two different penalty choices for a penalized-likelihood sinogram-restoration strategy we have been developing. One is a quadratic penalty we have employed previously and the other is a new median-based penalty.

Beam search heuristics for the single machine scheduling problem with linear earliness and quadratic tardiness costs [PDF]

open access: yes
In this paper, we consider the single machine scheduling problem with linear earliness and quadratic tardiness costs, and no machine idle time. We present heuristic algorithms based on the beam search technique.

A Soft Robotic Fish With a Dielectric Elastomer Actuator Body and Negative Stiffness Spine

open access: yesAdvanced Robotics Research, EarlyView.
This work introduces a bio‐mimetic soft robotic fish driven by fiber‐reinforced dielectric elastomer actuators integrated as its body. By prestretching this active skin against a flexible spine, a negative stiffness system is created, enabling large‐amplitude bending.

Efficient and Robust Standing Postures of Quadruped Robots

open access: yesAdvanced Robotics Research, EarlyView.
A calibrated static framework estimates load, optimizes torques, and adapts posture so quadruped robots stand efficiently and robustly under external payloads, achieving up to 50% lower torque demand. Inspired by the natural posture adjustments of animals under external loading, this article presents an optimization‐based framework for minimizing joint

Desirability-Based Multi-Response Robust Design Optimization of IPMSM Considering Manufacturing Uncertainty

open access: yesIEEE Access
Manufacturing uncertainties such as variations in material properties, dimensional tolerances, and assembly deviations of permanent magnets (PMs) significantly affect the mean and variance of key motor performances, including back electromotive force ...

Generalized Quadratic Revenue Functions [PDF]

open access: yes
In this paper we focus on specification of revenue functions in their dual price space. We consider two distance functions, both dual to the revenue function: Shephard output distance function and the directional output distance function, both in price ...

Robust Non-Negative LS-VCE for Three-Dimensional Surface Displacement Estimation From Multigeometry InSAR Observations

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
The variance component estimation (VCE) method has been extensively employed for the integration of interferometric synthetic aperture radar (InSAR) measurements acquired from multiple viewing geometries (i.e., differential InSAR, pixel offset-tracking ...

Nonreciprocal Swarmalators With Reconfigurable and Controllable Formations for Robot Collectives

open access: yesAdvanced Robotics Research, EarlyView.
Nonreciprocal swarmalator interactions are enabled through control barrier functions to transform self‐organizing robot collectives into reconfigurable, constraint‐aware systems. Complex two‐ and three‐dimensional shapes, continuous morphing, obstacle‐aware navigation, collective splitting, and object transport emerge from modulating agent‐level ...
