Multicluster Distributed Optimization Strategy for Turbine Wake Environment

Advanced Intelligent Systems, EarlyView.
This article studies the wake analysis of wind farms in different aspects, including basic methods, clustering optimization, and wake optimization. Through multiclustering, the wake optimization in a specific wind farm environment is explored. And focusing on the time cost and other issues that need to be solved in practical applications, targeted ...

On piecewise isomorphism of some varieties

, 2011
Two quasi-projective varieties are called piecewise isomorphic if they can be stratified into pairwise isomorphic strata. We show that the m-th symmetric power $S^m(C^n)$ of the complex affine space $C^n$ is piecewise isomorphic to $C^{mn}$ and the m-th ...

On piecewise linear processes

Statistics & Probability Letters, 2014
Abstract The letter concerns piecewise deterministic processes controlled by a Markov flow with exponentially, Exp ( λ n ) , distributed interarrival times T n . Assuming all rates λ n to be different, we study the distribution of a piecewise linear process with jumps.

Self‐Rhythmic Soft Pneumatic Pressure Regulation System Based on Self‐Excited Oscillation of Jet Hose

Advanced Intelligent Systems, EarlyView.
This study presents a soft pneumatic pressure regulation system that uses self‐excited hose oscillations to convert constant pressure (90–150 kPa) into rhythmic output. Simulations and experiments demonstrate tunable oscillation frequencies (5.9–11.1 Hz) through adjustments in pressure, hose length, and jet hole diameter.

Dynamic Single‐Input Control of Multistate Multitransition Soft Robotic Actuator

Advanced Intelligent Systems, EarlyView.
A concept for reducing the number of control inputs to one in a system with N degrees of freedom, is presented. Incorporating structural instabilities, cleverly, enables choosing any desired trajectory out of (N!)2 with only one input. The concept is demonstrated experimentally, along with analytical insights and numerical simulations.

Approximation of curves with piecewise constant or piecewise linear functions

, 2019
In this paper we compute the Hausdorff distance between sets of continuous curves and sets of piecewise constant or linear discretizations. These sets are Sobolev balls given by the continuous or discrete $L^p$-norm of the derivatives. We detail the suitable discretization or smoothing procedure which are preservative in the sense of these norms ...

Time‐Dependent Effect of Prophylactic Trimethoprim‐Sulfamethoxazole on the Incidence of Serious Infections in Antineutrophil Cytoplasmic Antibody–Associated Vasculitis: A Target Trial Emulation Study

Arthritis &Rheumatology, EarlyView.
Objective The objective of this study was to investigate the effect of prophylactic trimethoprim‐sulfamethoxazole (TMP‐SMX) on the incidence of serious infections in patients with antineutrophil cytoplasmic antibody–associated vasculitis (AAV). Methods This multicenter cohort study was designed to emulate a target trial that studied 296 patients with ...

Wearable exoskeleton robot control using radial basis function‐based fixed‐time terminal sliding mode with prescribed performance

Asian Journal of Control, EarlyView.
Abstract This paper tackles the problem of robust and accurate fixed‐time tracking in human–robot interaction and deals with uncertainties. This work introduces a control approach for a wearable exoskeleton designed specifically for rehabilitation tasks.

On the Age Distribution of Classical Cepheids in the Galaxy

Astronomische Nachrichten, EarlyView.
ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...

A Comprehensive Model for Separating Systematic Bias and Noise in Metabolomic Timecourse Data—A Nonlinear B‐Spline Mixed‐Effects Approach

Biotechnology and Bioengineering, EarlyView.
A nonlinear B‐spline mixed effects model for the simultaneous detection and correction of systematic error in timecourse metabolomics data. Systematic errors–such as those from dilution or incomplete extraction–affect all metabolites similarly and can be corrected by fitting all metabolites together in a single model.
