PURPOSE To compare the efficacy and safety of the electromagnetic lithotripter in the treatment of pediatric lithiasis to that of the earlier electrohydraulic model. MATERIALS AND METHODS Two groups of children with lithiasis aged between 10 and 180 months who underwent extracorporeal shock wave lithotripsy (ESWL). In the first group (26 children), ESWL was performed by using the electrohydra...

PURPOSE To compare the effectiveness of novel nanosecond electropulse lithotripsy with standard electrohydraulic lithotripsy to demonstrate and authenticate their differences because both modalities appear to be similar. MATERIALS AND METHODS An in vitro fragmentation study was conducted using cuboid BegoStone phantoms, which mimic hard and soft stones, based on an established model. Three di...

The paper discusses electrohydraulic variable supply systems in different design concepts. In the forefront of discussion are concepts with constant and speed-controlled electric motor combination pumps, implemented within control strategies.

Electrohydraulic actuation systems offer definative position control and an energy-efficient solution. Such are widely used in mobile machinery, robotics, various stationary systems. Achieving good of actuator the variable displacement electrohydraulic system by open loop is objective this study. For square (reference position) control, amplitude taken as 0.1 m, at 0.05, 0.15 0.25 Hertz frequen...

Recycling is a potential solution to narrow the gap between supply and demand of raw materials for lithium-ion batteries (LIBs). However, efficient separation active components their recovery from battery waste remains challenge. This paper evaluates influence three routes liberation LIB (namely mechanical, thermomechanical, electrohydraulic fragmentation) on lithium metal oxides (LMOs) spheroi...

Electrohydraulic Stewart platform is a multi-input and multi-output mechanical-hydraulic coupling system, which has the advantages of large power-to-weight ratio high accuracy. It been widely used in construction machinery, aerospace, other fields. In actual working process, especially high-speed motion, movement process will produce impact vibration then affect stability, accuracy, service lif...
