Tool sequence optimization based on three logical modes of robot control via CPLEX optimization

Cluster tools have advantages of shorter cycle times, faster process development, and better yield for less contamination. The sequence of dual-arm cluster tools is a complex logistics process during the semiconductor production. Efficient use of cluster tools is naturally very significant to competitive fab operations. Generating an optimized sequence in a computationally efficient manner and assessing the quality of the requirements to improve the fab production are the key factors for semiconductor manufacturing productivity. The Petri net modeling is introduced to minimize the makespan of the process for the three different logical modes and select a better mode after comparing the makespan among the three logical modes. The tool sequence optimization problem is formulated as optimization firing transition sequences based on the Petri net and then the formulation is converted to be linearly solved by the branch-and-cut method in the standard commercial solver CPLEX. Special methods for the linear conversion are highlighted. Due to the limited calculation time requirement for the real production and the large scale of the problem, special methods for the efficiency tuning are applied according to the characteristics of the problem. Numerical testing is supported by one of the most advanced semiconductor enterprises and the computational results show significant improvement compared with the traditional manual sequence results.     

Capillary electrophoresis coupled with electrochemiluminescence for determination of cloperastine hydrochloride

Objective To investigate the electrochemiluminescence (ECL) behavior of cloperustine hydrochloride.Methods ECL intensity of tris (2,2'-bipyridyl) rutheniumo(Ⅱ) was enhanced, the method for the determination of dupernstine hydrochloride was established using capillary electrophoresis (CE) coupled with electrochemilumolinescence (ECL) detection. Results Under the optimum conditions, ECL intensity varied linearly with cloperastine hydrochloride concentration from 7.0×10-6 g/mL to 1.0×10-4 g/mL. The detection limit (S/N=3) was 8.05×10-7g/mL. he relative standard deviation of the ECL intensity and the migration time for 11 consecutive injections of 1.0 ×10-5g/mL cloperastine hydrochloride was 2.9% and 1.5%, respectively. This method was successfully applied to eloperastine hydrochloride tablet determination. Conclusion The method has been established, validated and applied for determination of cloperastine hydrochloride.

暗挖电力隧道对邻近既有桥梁桩基的影响分析

对成都市某暗挖电力隧道穿越邻近桥梁桩基问题建立二维有限元模型,分析了隧道开挖在不同的隧道埋深、隧道与桩基中心距下对邻近桥梁桩基的影响规律。分析结果表明:在桩隧中心距小于一定范围时,开挖对桩基的影响很大;桩身最大水平变形和最大弯矩的位置随着隧道埋深变化而变化,且当隧道埋深位于桩中上部时,桩身最大水平变形和最大弯矩相对较大。
