Transparent conductive electrodes (TCEs) are widely used in applications ranging from display devices to thin-film solar cells. It remains a challenge, however, for industry and academia to implement mass production of large-area TCEs at low cost and at high volumes. It is also difficult to fabricate TCEs with good electrical properties and high light transmittance levels. In this study, a novel large-area and high-performance TCE manufacturing method is demonstrated that combines the electric-field-driven fusion direct printing technique and the liquid bridge transfer method. The master molds of the TCEs are fabricated by the electric-field-driven fusion direct printing technology, then soft lithography and the liquid bridge transfer processes are used to form the TCEs on different substrates. The relationships between process parameters, and their effects on the fabrication of the TCEs are explored through experiments, and the optimal process parameters are established. Using these methods, grid and stripe TCEs on the glass substrates with an area of 50 mm × 50 mm, an average line width of 4 µm, a spacing of 200 µm, a transmittance effectiveness of 88.94% and 88.15% which was nearly same as the bare glass, and a sheet resistance of 12 Ω sq−1 were successfully manufactured. These results illustrate the feasibility of mass producing large-area TCEs with high performances and at low cost.

The fuel of HTGR is made of some spherical fuel elements with diameter of 60 mm. The cask of fresh fuel is used to temporarily store and transport such a kind of new spherical fuel elements, and it may drop during transport. The dropping process can be simulated by two ways. The first is the coupled Euler-Lagrange (CEL) method, in which the new fuel elements are taking as fluid and can be considered explicitly. The second is referred to as the equivalent mass method. In the method, the cask and the new fuel are not considered individually, and the mass of the new fuel elements is averagely allocated to the bottom head of the cask. The simulating result shows that the CEL method can describe the flow and inertial effects of the new fuel elements in the dropping process, and the lateral fluid dynamic pressure generated by fuel elements to the cask. The impact effect can be fully considered in the equivalent mass method. Results show that the impact force is stronger and the contact time is shorter than that of the CEL method. Finally, parameters of equivalent fluid in the CEL method are discussed. And the results show that the fluid model is reasonable. In one word, calculation results of the two methods can be combined in structural design, which will give a more reasonable design.

Tiny lagging-angle magnetic synchronizator application study, which is based on theory at distance, is developed to solve the sealing of radiation gas inside rotation devices of HTR-PM fuel hand system. Within the outer surface of synchronizator in-side rotor and inner surface of synchronizator outer rotor, two-sized heat-resisted permanent magnets have been intensively coated in NNSSNNSS style. Its shielding can adopted Ti6-Al-4V titanium alloy with special bearing to support the cold-state and hot-state experimental study. The results show that materials of all parts of synchronizator has not been weaken after 107Gy dose γ radiation. Synchronizator can meet the requirement of lagging angle, which must be smaller than 0.2 degree based on the control accuracy. But the reliability depends on the bearing arrangement form and their lubrication. Long term operation reliability of magnet driver device, should give priority to solving the oil-free lubrication problem of bearing. The optimal allocation test is carried out on magnet synchronizator and bearing hot-state test facility. And further engineer demonstrations in the operational reliability will be fully taken on full sized fuel handling hot-state test facility.Copyright © 2013 by ASME

To the information-based development of ship, a area-model network construct of ship integrated platform management system (IPMS) is proposed. The stochastic optimal control of fin stabilizers networked control systems under IPMS is investigated. When long delay of IPMS network is considered, a state space model is derived. A stochastic optimal controller with a quadratic performance index is designed. The simulation results show its effectiveness.

A global sliding-mode controller is developed for position and velocity control of AC servo system based on exponential acceleration/deceleration algorithm. The problem of position and velocity control in the system is analyzed first. On this foundation the exponential acceleration/deceleration algorithm is used to plan the velocity profile. At the same time, the time-varying sliding surface and equivalent control law are especially designed, which realizes the global sliding mode control during position, including acceleration, constant, deceleration, and positioning at low speed stages. The permanent magnet synchronous motor (PMSM) AC servo controller platform is built finally and the experiment is implemented. The experimental results demonstrate the feasibility and effectiveness of the proposed control scheme. The application experiment also proved the controller is more easy to realize and with universal performance.
