Decentralized Robust Disturbance-Observer Based LFC of Interconnected Systems [PDF]
IEEE Transactions on Industrial Electronics, 2022 This paper develops a novel decentralized controller for multi-area secondary load frequency control (LFC) of power systems. The proposed robust-adaptive approach estimates the external disturbance input and uncertainties, which are assumed to be matched with the control input.

Evaluation of heat transfer in humidification phenomena – Comparison between infrared thermography and numerical simulation [PDF]
MATEC Web of Conferences, 2019 Infrared thermography (IRT) is a non-destructive testing technology used to assess the performance of buildings. As a diagnosis tool for retrofit and conservation of buildings it helps understanding the anomalies by allowing “seeing” their causes in a ...

LHCb experience with LFC replication
Journal of Physics: Conference Series, 2008 Database replication is a key topic in the framework of the LHC Computing Grid to allow processing of data in a distributed environment. In particular, the LHCb computing model relies on the LHC File Catalog, i.e. a database which stores information about files spread across the GRID, their logical names and the physical locations of all the replicas ...
