The influence of moisture on the energy performance of retrofitted walls [PDF]

open access: yesMATEC Web of Conferences, 2020
The renovation of old building facades should be performed mainly considering the building energy demand reduction. For this purpose, it is necessary to select retrofitted solutions that should be able of minimizing heat losses through walls. However, it

Decentralized Robust Disturbance-Observer Based LFC of Interconnected Systems [PDF]

open access: yesIEEE 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.

The 3D printing challenge in buildings [PDF]

open access: yesE3S Web of Conferences, 2020
The rising awareness and usage of Building Information Modelling (BIM), a methodology that allows for better information management and communication amongst the several stakeholders of a building project, opened the construction sector's door to digital

Principal Components Analysis for the Interpretation of Humidification Phenomena—Preliminary Results

open access: yesProceedings, 2019
Moisture is one of the major causes of building decay, compromising the indoor air quality and the durability of building components. Infrared thermography is a non-destructive technique that can be used to prevent damage caused by the presence of water.

Resting-State Connectivity of the Left Frontal Cortex to the Default Mode and Dorsal Attention Network Supports Reserve in Mild Cognitive Impairment

open access: yesFrontiers in Aging Neuroscience, 2017
Reserve refers to the phenomenon of relatively preserved cognition in disproportion to the extent of neuropathology, e.g., in Alzheimer’s disease. A putative functional neural substrate underlying reserve is global functional connectivity of the left ...

Resilient Event-Triggered Load Frequency Control for Multi-Area Power System With Wind Power Integrated Considering Packet Losses

open access: yesIEEE Access, 2021
The congest in an open communication system may cause the failure of the load frequency control (LFC) scheme in the power system. Furthermore, the increase of wind power penetration degrades the stability of the LFC scheme.

The Importance of Moisture Content to the Emissivity of Ceramic Bricks

open access: yesProceedings, 2019
Emissivity is a key parameter if one intends to use quantitative thermography. The importance of temperature, surface characteristics, wavelength and the direction of the emitted radiation in the emissivity is well documented in the literature.

Introduction of Financial Settlement Among LFC Areas

open access: yesB&H Electrical Engineering, 2022
Abstract Settlement of unintended deviation between scheduled and realized energy exchange among LFC (Load Frequency Control) areas used to be conducted through the energy compensation programs, where energy deviation from period of registration is compensated at a later stage period of compensation of unintended ...
