This paper investigates the synergetic control strategy for water hammer wave and mass in hydropower station with downstream channel. Firstly, mathematical model of channel (HSDC) surge tank (HSDCST) are established. Then, controller formula HSDC HSDCST derived on basis theory. Furthermore, it is parsed that dynamic characteristics to various disturbances under strategy. Finally, robustness app...

The stability of the power system is a critical issue for reliable and safe operation network. Where maintaining voltage levels constant or within prescribed permissible limit robustness against disturbances, while working near its margin due to growth consumption, nowadays are great challenges. Chaotic oscillation in network may lead bus collapse, angle divergence possibly both phenomena simul...

Railways were originally uniquely identified with the material of their initial construction and now are technically identified by the characteristic contact of ‘steel wheel on steel rail’. Over 160 years ago failures of iron railway axles led to research into what we now know as metal fatigue. Accidents throughout the ages have acted as catalysts for research and improvements: this lecture wil...

The Speech Cycling Task (SCT) is a novel experimental paradigm developed together with Robert Port and Keiichi Tajima at Indiana University. In a SCT, subjects repeat a phrase containing multiple prominent, or stressed, syllables in time with an external timer, which can be simple or complex. A phase-based collective variable is deened in the acoustic signal. This paper reports on two experimen...

Irreversible processes can be described in Open non-equilibrium thermodynamic systems, of topological dimension 4. By means of Continuous Topological evolution, such processes can cause local decay to Closed non-equilibrium thermodynamic states, of topological dimension 3. These topologically coherent, perhaps deformable, regions or states of one or more components appear to "emerge" as compact...
