Design of a Reconfigurable Robotic System for Flexoextension Fitted to Hand Fingers Size

Applied Bionics and Biomechanics, Volume 2016, Issue 1, 2016., 2016
Due to the growing demand for assistance in rehabilitation therapies for hand movements, a robotic system is proposed to mobilize the hand fingers in flexion and extension exercises. The robotic system is composed by four, type slider‐crank, mechanisms that have the ability to fit the user fingers length from the index to the little finger, through the

Limit Cycle Analysis in a Class of Hybrid Systems

Mathematical Problems in Engineering, Volume 2016, Issue 1, 2016., 2016
Hybrid systems are those that inherently combine discrete and continuous dynamics. This paper considers the hybrid system model to be an extension of the discrete automata associating a continuous evolution with each discrete state. This model is called the hybrid automaton. In this work, we achieve a mathematical formulation of the steady state and we

A Difficult Start for the UK Labour Government, But Time Is Still on Their Side

World Affairs, Volume 188, Issue 3, Fall 2025.
ABSTRACT The newly elected Labour Government in the United Kingdom promised change. However, the first 10 months have been disappointing, characterized by misjudged announcements regarding the Winter Fuel Allowance and Employers' National Insurance contributions. Yet, there is still time to get back on track with welfare reform and create a new welfare

Fuzzy Networked Control Systems Design Considering Scheduling Restrictions

Advances in Fuzzy Systems, Volume 2012, Issue 1, 2012., 2012
Nowadays network control systems present a common approximation when connectivity is the issue to be solved based on time delays coupling from external factors. However, this approach tends to be complex in terms of time delays. Therefore, it is necessary to study the behavior of the delays as well as the integration into differential equations of ...

Sensorless Estimation Based on Neural Networks Trained with the Dynamic Response Points

Sensors, 2021
In the present work, a neuronal dynamic response prediction system is shown to estimate the response of multiple systems remotely without sensors. For this, a set of Neural Networks and the response to the step of a stable system is used.

New opportunities and challenges for conservation evidence synthesis from advances in natural language processing

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract Addressing global environmental conservation problems requires rapidly translating natural and conservation social science evidence to policy‐relevant information. Yet, exponential increases in scientific production combined with disciplinary differences in reporting research make interdisciplinary evidence syntheses especially challenging ...

H2 guaranteed cost control of discrete linear systems

Mathematical Problems in Engineering, Volume 6, Issue 5, Page 425-437, 2000., 2000
This paper presents necessary and sufficient conditions for the existence of a quadratically stabilizing output feedback controller which also assures H2 guaranteed cost performance on a discrete linear uncertain system where the uncertainty is of the norm bounded type.
