A New Active Disturbance Rejection Control Tuning Method for High-Order Electro-Hydraulic Servo Systems

open access: yesActuators
In our industry, active disturbance rejection control already has been used to enhance the performance of the electro-hydraulic servo systems, despite the fact that electro-hydraulic servo systems are usually reduced to first-order and second-order ...

CONCERT: A Modular Reconfigurable Robot for Construction

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1332-1362, May 2026.
ABSTRACT This paper presents CONCERT, a fully reconfigurable modular collaborative robot (cobot) for multiple on‐site operations in a construction site. CONCERT has been designed to support human activities in construction sites by leveraging two main characteristics: high‐power density motors and modularity. In this way, the robot is able to perform a

Beyond feasibility filters: How expertise heterogeneity enables innovation recognition

open access: yesStrategic Management Journal, Volume 47, Issue 5, Page 1368-1432, May 2026.
Abstract Research Summary Organizations often struggle to identify promising innovations that balance novelty and feasibility in multidisciplinary domains, yet how does evaluator expertise heterogeneity shape these assessments? This study examines how evaluator expertise influences innovation evaluation through a field experiment with National ...

Exact solutions and physical analogies for unidirectional flows

open access: yes, 2016
Unidirectional flow is the simplest phenomenon of fluid mechanics. Its mathematical description, the Dirichlet problem for Poisson's equation in two dimensions with constant forcing, arises in many physical contexts, such as the torsion of elastic beams,

Introduction to the Phillips Machine and the Analogue Computing Tradition in Economics [PDF]

open access: yes
In this paper I try to argue for the desirability of analog computation in economics from a variety of perspectives, using the example of the Phillips Machine. Ultimately, a case is made for the underpinning of both analog and digital computing theory in
