Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract The present study was conducted as part of a comprehensive work to establish National Diagnostic Reference Levels (NDRLs) in Sri Lanka for the first time. DRLs can be used as an effective optimization tool for identifying unusually high or low patient doses during X‐ray examinations.

On gray-box modeling for virtual flow metering [PDF]
Control Engineering Practice, volume 118, 2022, 2021 A virtual flow meter (VFM) enables continuous prediction of flow rates in petroleum production systems. The predicted flow rates may aid the daily control and optimization of a petroleum asset. Gray-box modeling is an approach that combines mechanistic and data-driven modeling.

On the Determination of the Solar Rotation Elements i, Ω and Period using Sunspot Observations by Ruđer Bošković in 1777 [PDF]
The Mining-Geology-Petroleum Engineering Bulletin, 2021, 36, 3,
pp. 77-98, 2022 In September 1777, Ru{\dj}er Bo\v{s}kovi\'c observed sunspots for six days. Based on these measurements, he used his own methods to calculate the elements of the solar rotation, the longitude of the node, the inclination of the solar equator and the period.

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Modeling pressure pulsation and backflow in progressing cavity pumps with deformable stator [PDF]
Journal of Petroleum Science and Engineering (2021), 203, 108402, 2021 This contribution studies the impact of the rotor-stator interaction in a single-stage progressing cavity pump on the flow rate and pressure. Specifically, we investigate the effect of the rotor movement on the sealings formed with deformable stators for various speeds and pressures. Sealings are reconstructed with the help of a geometric 3D model.

Making the black-box brighter: interpreting machine learning algorithm for forecasting drilling accidents [PDF]
Journal of Petroleum Science and Engineering, 2022, 111041, ISSN
0920-4105, 2022 We present an approach for interpreting a black-box alarming system for forecasting accidents and anomalies during the drilling of oil and gas wells. The interpretation methodology aims to explain the local behavior of the accident predictive model to drilling engineers.

Multi-task learning for virtual flow metering [PDF]
, 2021 Virtual flow metering (VFM) is a cost-effective and non-intrusive technology for inferring multiphase flow rates in petroleum assets. Inferences about flow rates are fundamental to decision support systems that operators extensively rely on. Data-driven VFM, where mechanistic models are replaced with machine learning models, has recently gained ...

Monitoring Global Science of Petroleum Engineering Based on Co-citation Analysis Networks
International Journal of Information Science and Management, 2022 The development of purposeful and principled programs meant to improve the scientific level of countries requires the assessment and measurement of research, and oil industry research is no exception. Therefore, examining the quantitative and qualitative
