“Is percutaneous extraction of gallstones safe and effective in high-risk patients? Evidence from a systematic review”
(
Elsevier
, 2022 , Article)
Gallstone disease in high-risk patients presents a management dilemma as cholecystectomy is often not performed due to their co-morbidities. Alternatively, such patients can be managed by percutaneous removal of gallstones. ...
Application of Machine Learning Classification Algorithms for Two-Phase Gas-Liquid Flow Regime Identification
(
Society of Petroleum Engineers
, 2021 , Conference Paper)
This research aims to identify the best machine learning (ML) classification techniques for classifying the flow regimes in vertical gas-liquid two-phase flow. Two-phase flow regime identification is crucial for many ...
Horizontal Two-Phase Flow Regime Identification with Machine Learning Classification Models
(
International Petroleum Technology Conference (IPTC)
, 2022 , Conference Paper)
This paper presents a follow-up study to Manikonda et al. (2021), which identified the best machine learning (ML) models for classifying the flow regimes in vertical gas-liquid two-phase flow. This paper replicates their ...
Experimental analysis of water evaporation losses in cooling towers using filters
(
Elsevier
, 2020 , Article)
Water evaporation losses in cooling towers account for considerable amount of fresh water consumption, which calls for proven and economically viable technologies to address this problem. The use of filters mounted on to ...
Turbulence modeling using Z-F, RSM, LES and WMLES for flow analysis in Z-Shape ducts
(
American Society of Mechanical Engineers (ASME)
, 2020 , Conference Paper)
Turbulent flow in Z-shape duct configuration is investigated and analyzed using Reynolds Stress Model (RSM), Large Eddy Simulation (LES), ζ-f Model, and Wall-Modeled Large Eddy Simulation (WMLES). The results are validated ...
Combined heat and power system based on Solid Oxide Fuel Cells for low energy commercial buildings in Qatar
(
Elsevier
, 2021 , Article)
Commercial buildings in Qatar account for 19% of the total energy consumption in the country. To reduce this significant amount of energy, a Solid Oxide Fuel Cell Combined Heat and Power (SOFC CHP) system with natural gas ...
Heat transfer measurements of Polyalpha-Olefin- boron nitride nanofluids for thermal management and lubrication applications
(
Elsevier

In this paper, the first study is reported combining Polyalpha-Olefin (PAO) oil with hexagonal Boron Nitride (hBN) to produce new class of nanofluids for heat transfer and lubrication applications. The heat transfer ...
Optimising small-scale electronic commerce supply chain operations: a dynamic cost-sharing contract approach
(
Springer
, 2022 , Article)
For small-scale electronic commerce supply chains, designing effective strategies to improve operational effectiveness, market share and long-term survival are essential aspects. However, researchers have given less attention ...
Dataset for measured viscosity of Polyalpha-Olefin- boron nitride nanofluids
(
Elsevier
