The proposed four ports cylinder was simulated and parameters such as ports sizes, loads and pressures are varied during the simulation.
The hydraulic resisting forces, piston speed and mass flow rates are computed. Chenoweth, Aircraft flight control actuation system design vol.

The small sized outlet ports of the cylinders resist the flow of discharged oil; and as a result the piston motion is slowed down.

However, no computer can process the near infinite number of atoms in objects, so instead we model 'finite' groups of them.
In the real world, everything that occurs results from the interaction between atoms (and sub-particles of those atoms). If we were to simulate the world in a computer, we would have to simulate this interaction based on the simple laws of physics.

This paper presents a review of PSO application in Economic Load Dispatch problems.
A new hydraulic system was proposed as a solution to relieve the hydraulic resistance in the actuators.
The proposed system is a four ports hydraulic cylinder fitted with a novel flow control valve. Goldenberg, "Design of a new high performance electrohydraulic actuator," in Proceedings of The International Conference on Advanced Intelligent Mechatronics, IEEE/ASME,, 1999, pp.
This causes a lot of heat generation and energy loss within the actuators.
