Application of Time Series Analytics to Assess Performance of Artificial Lift Systems Deployed in Coal Seam Gas (CSG) Wells
Artificial Lift Systems (ALS) play a crucial role in producing natural gas from Coal Seam Gas (CSG) wells in Australia. These systems are employed in over five thousand wells located in the Bowen and Surat Basins of Queensland. Operators face significant challenges in managing and maintaining …

Quality and quantity of service in lift groups
… quality of service experienced by passengers in lift systems where multiple cars are sharing same shafts (multi car lift systems) and destination control. These modern lift systems have opportunities and constraints for control algorithms arising by existing and additional quality of service …

The Modelling and Simulation of the Dynamic Behaviour of a Lift Car-Rope Suspension System
Vibration may influence all lift components and affect the ride quality of a lift. In particular, lateral and longitudinal vibrations of hoist, compensating ropes and travelling cables can occur and car vibrations may take place. The design methodology of lift systems requires performing a thorough …

Performance, Stability and Control of Electric Short Takeoff and Landing Aircraft
… the wing lead edge is used to enhance the wing lifting capability, enabling reductions in required field length or improvements in cruise efficiency compared to aircraft with conventional high lift systems. DEP blown lift enables the development of a new class of electric super-short takeoff and …

Wake bursting: a computational and experimental investigation for application to high-lift multielement airfoil design
"High-lift aerodynamic flowfields are complex, and the potentially-adverse wake development associated with these high-lift systems is not fully understood. Thus, an exhaustive investigation including both experimental and computational efforts is needed to gain an increased understanding of the …
