Adaptive blind source separation algorithm based on the estimated number of dynamic fault source In the detection and diagnosis of the rotating machinery failures, especially in large-scale equipment in the harsh environment of the metallurgy, building materials, mining and other industries, environment and device status often take the responsibility of equipment operating in a sub-healthy condition, where the signal sources of multiple faults are mixed at the same time, and even the number of the failure source exceeds the number of sensors.

It is the kernel of initiatively changing damp control to set up the damper which damping ratio is adjustable onto flexible manipulator to adjust the damp of its elastic vibration . this kind of control method of setting the initiatively changing damp equipment onto flexible manipulator arm is different from the control method of sticking strong damp material onto flexible manipulator arm , the former is called the passive control , the latter is called initiative control .

ECM is a comprehensive disciplines involving fluid dynamics, electrochemistry, materials science and others [1, 2] and has been used as an advanced manufacturing technology in many fields.
Adhesion between the film and substrates and components were mainly dependent on current density as well as polarization curves of materials.
So, current density should be set carefully according to machining parameters, electrolyte and polarization curves of materials.

As a function of chlorophyll in the energy collector, Noni leaves were used as an organic material in solar cell in order to increase the energy conversion efficiency.
The reason is to remove any unwanted materials left from the leaf.
