Drag prediction of rough-wall turbulent flow using data-driven regression

Flow
Efficient tools for predicting the drag of rough walls in turbulent flows would have a tremendous impact. However, accurate methods for drag prediction rely on experiments or numerical simulations which are costly and time consuming.

A two-weight estimate for a class of fractional integral operators with rough kernel

International Journal of Mathematics and Mathematical Sciences, 2005
We prove that the operators in a class of rough fractional integral operators and the related maximal operators are bounded from Lp(vp) to Lq(uq) with weight pair (u,v).

The Schroedinger Equation with Potential in Rough Motion [PDF]

, 2011
This paper proves endpoint Strichartz estimates for the linear Schroedinger equation in $R^3$, with a time-dependent potential that keeps a constant profile and is subject to a rough motion, which need not be differentiable and may be large in norm.

Asymmetry in Skipping Enhances Viability Against Control Input Noise

Advanced Robotics Research, EarlyView.
Quadruped animals use asymmetric galloping gaits at high speeds, yet the functional role of this asymmetry remains unclear. This study shows that left–right asymmetry in touchdown angles enhances robustness to control noise. Using a simple two‐legged locomotion model and viability theory, it demonstrates that asymmetric skipping substantially enlarges ...

Diagnosis and Knowledge Discovery of Turner Syndrome Based on Facial Images Using Machine Learning Methods

IEEE Access, 2020
Turner syndrome (TS) is a chromosomal disorder disease that only affects the development of females. Based on TS facial images, we propose a new TS diagnosis model, which preserves the original ratio of face width to face height, extracts reliable ...

Singular integral operators with rough convolution kernels [PDF]

Journal of the American Mathematical Society, 1996
The author treats singular integral operators \(T\) with convolution kernel \(K\). He introduces the two quantities \[ V(\theta)= \sup_{R>0} \int^{2R}_R |K(r\theta)|r^{n-1} dr,\quad \theta\in S^{n-1}, \] and \[ \eta(\alpha)= \sup_{R\geq as} \int_{S^{n-1}} \int^{2R}_R |K((r- s)\theta)- K(r\theta)|r^{n-1} dr d\theta. \] Assuming \(T\) is bounded on \(L^2\

ChicGrasp: Imitation‐Learning‐Based Customized Dual‐Jaw Gripper Control for Manipulation of Delicate, Irregular Bio‐Products

Advanced Robotics Research, EarlyView.
Automated poultry processing lines still rely on humans to lift slippery, easily bruised carcasses onto a shackle conveyor. Deformability, anatomical variance, and hygiene rules make conventional suction and scripted motions unreliable. We present ChicGrasp, an end‐to‐end hardware‐software co‐designed imitation learning framework, to offer a ...
