Data Resource Profile: The Social Services Client Administration and Retrieval Environment (SOSCARE) administrative dataset for children’s social care in Northern Ireland

International Journal of Population Data Science
Introduction Children in contact with the children's social care (CSC) system are a vulnerable group likely to have experienced one or multiple forms of childhood adversity.

Probabilistic linkage to enhance deterministic algorithms and reduce data linkage errors in hospital administrative data

Journal of Innovation in Health Informatics, 2017
Background: The pseudonymisation algorithm used to link together episodes of care belonging to the same patient in England [Hospital Episode Statistics ID (HESID)] has never undergone any formal evaluation to determine the extent of data linkage error ...

The Booting‐Type ADRC of Airborne Photoelectrical Platform [PDF]

Mathematical Problems in Engineering, 2014
Customary disturbance rejection in the photoelectrical platform is “passive,” which makes it difficult to further improve the isolation degree owning to the strict restriction of mechanical resonance frequency. In this paper, a booting‐type ADRC is proposed, whose disturbance estimation process is guided by target value to reduce the overshoot and lag ...

Does change in area-level deprivation, change health outcomes? A latent class growth analysis of population data

International Journal of Population Data Science
Objectives Trajectories of social mobility may be a more informative predictor of health than point-in time analyses. We sought to identify area-level deprivation trajectories within the Northern Ireland (NI) population and their associations with ...

Social and spatial mobility and self-reported heath in older-age: linkage of the Scottish Longitudinal Study to the Scottish Mental Survey 1947

International Journal of Population Data Science, 2018
Background There is debate within the literature as to whether social mobility inflates or constrains health inequalities. The role of geographical mobility is unknown.

Model-Based Control with Active Disturbance Rejection Algorithm for a Diesel Engine

Complexity, 2023
To improve the speed control performance of a diesel engine, the active disturbance rejection controller (ADRC) is designed by adding an arranging transition process to the traditional PID controller, extracting differential signals reasonably, and ...

The Improved Particle Swarm Optimization Method: An Efficient Parameter Tuning Method with the Tuning Parameters of a Dual-Motor Active Disturbance Rejection Controller

Sensors, 2023
Dual-motor control systems require high synchronization maintenance. Active disturbance rejection controllers (ADRC), renowned for their exceptional immunity to interference, rapid response time, and robustness, have gained widespread adoption as a ...

Invariance Principle and ADRC Development

IOP Conference Series: Earth and Environmental Science, 2019
After reading a lot of data, the author believes that cybernetics will change from the model theory of direct control deviation to the cybernetics of controlling internal and external disturbances according to the invariance theory in the future. Since Watt's steam engine in 1788, the theory of automatic control has developed rapidly.

Adaptive sliding mode based active disturbance rejection control method for a direct-driven wind power conversion system

The Journal of Engineering, 2019
Considering the internal and external disturbances of the direct-driven wind energy conversion systems, i.e. multi-variable coupling, non-linear characteristic and modelling error, and the environmental disturbances, an adaptive sliding mode observer ...
