ABSTRACT In this dissertation, fault-tolerance of redundant manipulators is thoroughly investigated. First, inherent relationship between the dexterity and fault-tolerance of single-redundancy manipulator is discussed. Both the manipulability and the relative manipulability are utilized for measuring the kinematic fault-tolerance of the manipulator with one joint failure. Furthermore, the relative manipulability is used for measuring dexterity loss resulted by one joint failure, and the relationship between the fault-tolerance measurement and null space vector of Jacobian matrix is established.

From the lifespan of relay point of view, a reliability criterion was provided based on dynamic characteristics of anti-forces. Mathematical model of tolerance design with reliability was set up under usage of "stress-strength interference method", taken some critical dynamic characteristics as identification objects such beginning of contact separation speed, speed of collision and gag bit impact velocity. This model showed that lower values of characteristic parameters center and quantitative descriptively relationship between tolerance and product reliability. Multi-objective optimization model of relay tolerance distribution was completed when some factors such as reliability, processing costs and its feasibility into consideration. Based on Analytic Hierarchy Process to determine weight coefficients of various objectives, and usage of simulated annealing, this study performed optimal reliable tolerance allocation of space electromagnetic relay, and then key technology segments were analyzed, accompanying its course measured by controlling chart.

That means Pho85 kinaseand calcineurin were involved in salt tolerance with an identical target protein or in 中科院上海生化与细胞所博士学位论文摘要 the same pathway. Inhibition of calcineurin decrease the YPH499, pho80? mutant,and pap1 (pcl7)? mutant Mn2+ tolerance but not that of pho85? mutant and thepho85? mutant was more sensitive to Mn2+ than YPH499, pho80? mutant, and pap1(pcl7)? mutant even with the addition of cyclosporin A. Therefore, the conclusioncould be drawn that PHO85 gene played a dominant role in Mn2+ homeostasisregulation in compare with calcineurin. As for Ca2+ tolerance, cyclosporin A canincrease the tolerance to Ca2+ of all the mutant mention above, that means Pho85kinase and calcineurin function antagonistically in regulation of Ca2+ homeostasis.In Bioinformatics, BRI3 gene is a novel gene without any function clue but givehigh conservation in mammalian.
