A modified simulated annealing algorithm and an excessive area model for floorplanning using fixed-outline Article

De-xuan ZOU,Gai-ge WANG,Gai PAN,Hong-wei QI

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 11,   Pages 1228-1244 doi: 10.1631/FITEE.1500386

Abstract: Outline-free floorplanning focuses on area and wirelength reductions, which are usually meaningless,We concentrate on a more difficult and useful issue, fixed-outline floorplanning.This issue imposes fixed-outline constraints on the outline-free floorplanning, making the physical design, n30, n50, n100, n200, and n300—are chosen to demonstrate the efficiency of our proposed method on fixed-outlineefficient in obtaining desirable objective function values associated with the chip area, wirelength, and fixed-outline

Selective reduction of NO by photo-SCR with ammonia in an annular fixed-film photoreactor

YiangChen CHOU, Young KU

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 149-155 doi: 10.1007/s11783-010-0296-9

Abstract: Gaseous NO was photocatalytically reduced at room temperature by photo-assisted selective catalytic reduction (photo-SCR) with ammonia over TiO in this study. NO reduction efficiency and N selectivity were determined from gases composition at the outlet stream of photoreactor. Effect of operating conditions, e.g. light intensity and inlet concentrations of ammonia and oxygen, on the NO reduction efficiency and N selectivity were discussed to determine the feasible operating condition for photocatalytic reduction of NO. Experimental results showed that selective catalytic reduction of NO with ammonia over TiO in the presence of oxygen was a spontaneous reaction in dark. The photoirradiation on the TiO surface caused remarkable photocatalytic reduction of NO to form N , NO , and N O under 254 nm UV illuminations, while almost 90% of N selectivity was achieved in this study. The ammonia and oxygen molecules played the roles of reductant and oxidant for NO reduction and active sites regeneration, respectively. The reduction of NO was found to be increased with the increase of inlet ammonia and oxygen concentrations until specific concentrations because of the limited active sites on the surface of TiO . The kinetic model proposed in this study can be used to reasonably describe the reaction mechanism of photo-SCR.

Outline of Strip Rolling Technological Control Theory

Zhang Jinzhi

Strategic Study of CAE 2001, Volume 3, Issue 4,   Pages 46-55

Abstract:

Classical rolling theory, which is based on the law of the lowest resistance,the condition of constant volume and the condition of equal flow per second,has formed a fairly integrated rolling applied technology science system by means of experiment and deduction. This system reflects only the static law of rolling process,so it is necessary to control dynamic rolling process by drawing high and new technology such as cybernetics, information theory and computer science into the system.During the history of rolling theory, classical rolling theory based on mechanics took the lead before the establishment of spring equation, after that the rolling process control theory based on mechanics and cybernetics took precedence. In this paper,the concept of technological control theory is put forward. A new theory system, which is based on fundamental rolling technology control theory, is set up. Its main content included：the tension theory system in continuous rolling, which reflects the negative feedback effect of tension, is set up;disturbance survey problem is settled in gauge control process;shape theory system, which resembles gauge control theory,by defining dual parameter,is established.

Keywords： continuous rolling process control     tension in continuous rolling     gauge control     shape stiffness     spring equation for rolling mill     comprehensive equal reserves for load distribution
