Acoustic Emission Monitoring of Fatigue Crack Growth in Mooring Chains

Applied Sciences, 2019
Offshore installations are subject to perpetual fatigue loading and are usually very hard to inspect. Close visual inspection from the turret is usually too hazardous for divers and is not possible with remotely operated vehicles (ROVs) because of the ...

Integrating an agent-based wireless sensor network within an existing multi-agent condition monitoring system [PDF]

, 2009
The use of wireless sensor networks for condition monitoring is gaining ground across all sectors of industry, and while their use for power engineering applications has yet been limited, they represent a viable platform for next-generation substation ...

Condition Monitoring with Incomplete Observations

, 2014
We introduce an approach for predicting the behaviour of a machine during a production cycle. Typical data analysis methods assume that continuous behaviour is (fully) observed. This assumption is unrealistic as monitored machines are often interrupted and restarted at irregular points in time.

Numerical simulation study of novel air-cooled condenser with lateral air supply

Case Studies in Thermal Engineering, 2019
Uneven distribution of internal temperature and air flow field are considered to be the essential defects of the Λ-frame air-cooled condenser (ΛACC) in a power plant.

Remote machine condition monitoring based on power supply measurements [PDF]

The most widely used rotating machines in the industry are three phase alternative current (AC) induction machines. With the advances in variable speed drive (VSD) technology, they have become even more reliable than their direct current (DC) counterpart.

Study on Outlet Temperature Control of External Receiver for Solar Power Tower

Energies, 2021
Due to the change of direct normal irradiance (DNI) and the change of output power load, the receiver of the solar tower is in an unstable state in the actual operation. In this paper, a 100 MW external cylindric receiver is designed and modelled.

Evaluation of the Homogeneity of Geochemical Reference Materials by Wavelength-Dispersive X-Ray Fluorescence Spectrometry Using 0.1 g Fusion Samples

Journal of Chemistry
Good homogeneity is a critical guarantee for the accuracy of certified reference material values. X-ray fluorescence spectrometry (XRF) is widely used for the homogeneity testing of geochemical reference materials due to its simple sample preparation and

Early Body Mass Index z‐Score Change and Resolution of Severe Malnutrition in Children With Sickle Cell Anemia in a Low‐Income Setting: A Prospective Single‐Arm Extension Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Children with sickle cell anemia (SCA) in low‐income settings are at risk of severe malnutrition, but optimal nutritional management has not been established. We evaluated an intensified ready‐to‐use therapeutic food (RUTF) regimen in children with persistent severe malnutrition after initial treatment and assessed whether early ...
