Confronting Backlash States

Understanding the managed care backlash.

This paper examines the depth and breadth of the public backlash against managed care and the reasons for it. We conclude that the backlash is real and influenced by at least two principal factors: (1) A significant proportion of Americans report problems with managed care plans; and (2) the public perceives threatening and dramatic events in managed care that have been experienced by just a fe...

What's behind the public's backlash?

Modeling of backlash in drivetrains

The presence of backlash in drivetrains is a major source of limitations as it introduces nonlinearities that reduce their efficiency in speed and position control. Existing models in backlash assume massless shaft, and use only elasticity and damping properties to describe the transmitted torque. This assumption makes them inaccurate since it does not account for the contribution of the body’s...

Self-learning Backlash Inverse Control of Cooling or Heating Coil Valves Having Backlash Hysteresis

Valves are widely used in HVAC systems to regulate liquid flow rate, such as hot and chilled-water valves utilized in cooling and heating coils. These valves are typically controlled with motorized actuators where significant backlash hysteresis might exist and the backlash magnitude mostly depends on the clearance of the manufactured gearbox. Due to the hysteresis effect, unsatisfactory tracki...
