When designing a new system, designers have to do sizing of components with limited information about the overall system, let alone of the control, if necessary. What they often know are the boundary conditions and desired behavior in terms of transients of temperature, motion, charge, force etc. The idea of backward or inverse simulation is to simulate the component or machine behavior on the basis of boundary conditions and desired performance without implementing control. Many machines could be designed to be more efficient, if inverse system simulation would be available in early stages of the design.
Recently, several research groups have proposed actuators suitable for operation in MRI scanners (Magnetic resonance imaging). Their main feature is the design of non-magnetic material to avoid distortion of the imaging. Pneumatic actuators are a drive of choice for such actuators because they do not depend on the use of magnetic material.
We have currently testing a reduced complexity pneumatic master/slave teleoperation system that has the capability of force feedback for the operator in an adjacent room without using force sensors.
Lebanon has announced 2010 in the Policy Paper for the Electricity Sector that by 2020, that 12% of the national electric and thermal supply should be coming from renewable sources.
We are working on a refined model for the coastal wave climate of Lebanon that can be used for improved fore and hindcasting. We are also testing the performance of hydraulic power-take-off mechanisms for the use of wave-powered desalination.
