Abstract Language impairment, or aphasia, is a disabling symptom that affects at least one
third of individuals after stroke. Some affected individuals will spontaneously recover partial …

Flow control is a very common objective in fluid power systems. Usually, controlling the
force, velocity, position, etc. of hydraulic actuator is achieved by adjusting the flow rate of the …

This book combines real problems of practical interest with an application of profound
theory. The mathematical model is derived step by step on the basis of physical principles …

Efficiency improvement in piston pumps and motors is a major task in pump development.
Just a small improvement in efficiency can have a significant financial impact, particularly on …

This paper describes the design of a swash plate axial piston pump and the theoretical
models describing the bulk modulus of aerated and non-aerated fluids. The dead space …

This paper analyzes the pressure distribution, leakage, force, and torque between the barrel
and the port plate of an axial piston pump. A detailed set of new equations is developed …

The present paper deals with the pressure control of self-supplied variable displacement
axial piston pumps subject to fast changing, unknown loads. First, the setup of the system …
