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

Proceedings, 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.

The influence of fly ash and foam contents on the properties of lightweight foamed concrete

Vietnam Journal of Science, Technology and Engineering, 2022
Due to rapid industrialization and modernization, a large number of both fly ash (FA) and ground granulated blast furnace slag (GGBFS), both by-products from thermal power plants and steel factories, are increasing day by day.

Subclinical Optic Nerve Involvement in Radiologically Isolated Syndrome: Multimodal Detection and Diagnostic Impact

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives We aimed to determine the frequency of subclinical optic nerve (ON) lesions using MRI, optical coherence tomography (OCT), and visual evoked potentials (VEP) in radiologically isolated syndrome (RIS), and to assess their diagnostic and prognostic significance.

Applying colour-coded particle image velocimetry to the wake of a delta wing across a wide range of angles of attack

Journal of Fluid Science and Technology
The forces acting on a delta wing are predominantly influenced by local flow structures, specifically leading-edge vortices (LEVs). This study applies colour-coded particle image velocimetry (PIV) to quantify wake dynamics and lift generation for a delta

Status quo and development trend of lost foam casting technology [PDF]

China Foundry, 2014
Lost foam casting (LFC) technology has been widely applied to cast iron and cast steel. However, the development of LFC for Al and Mg alloys was relatively slower than that for cast iron and cast steel.

Introduction of Financial Settlement Among LFC Areas

B&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 ...

Anti‐CD20 Discontinuation Versus Continuation in People Aged Over 50 With Non‐Active Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To determine whether discontinuing anti‐CD20 therapy in people with relapsing‐onset MS aged over 50 is associated with an increased risk of relapse, inflammatory activity, confirmed disability accrual, and serious infection compared with continuing therapy.

Tie-Line Bias Control Applicability to Load Frequency Control for Multi-Area Interconnected Power Systems of Complex Topology

Energies, 2017
The tie-line bias control (TBC) method has been widely used in the load frequency control (LFC) of multi-area interconnected systems. However, it should be questioned whether the conventional TBC can still apply to LFC when considering the complication ...
