Reduced SQP based on orthonormal bases, orthogonal bases and coordinate bases are studied and compared. With the correction item introduced, the null-space move is adjusted and the reduced SQP based on coordinate bases decomposition is improved.●The key problem of steady-state data processing for RTOPT is studied. A new algorithm of simultaneous strategies for data reconciliation and gross error detection is proposed. Here the objective function that is constructed using maximum likelihood principle and joint distribution function is minimized. Efficient algorithm is developed which exploited the nonlinear lease-square structure of this objective function.

For, such banished man is entirely cut off from society; and such a monk, upon his profession, renounces solemnly all secular concerns: and besides, as the popish clergy exclaimed an exemption from the duties of civil life, and the commands of the temporal magistrate, the genius of the English law would not suffer those persons to enjoy the benefits of society, who secluded themselves from it, and refused to submit to its regulations.25 A monk is therefore accounted civiliter mortuus , and when he enters into religion may, like other dying men, make his testament and executors; or, if he makes none, the ordinary may grant administration to his next of kin, as if he were actually dead intestate.
因为,这样被驱逐的人完全的与社会隔绝;这样的修士,基于他的宣誓,庄严的放弃了所有世俗的社会关系:此外,既然天主教神职人员宣称免除世俗生命的责任并免受世俗管理者的命令,英格兰法律的精神便不能忍受这些人再享受世俗社会的好处,他们将自己与社会隔绝开来,并拒绝服从社会的约束。所以,修士被视为法律上的死亡,当他进入宗教,如同其他将死的人一样,可以确定他的遗嘱和遗嘱执行人;如果他没有确定,遗嘱官员可以将财产管理权力授予他最近的亲属,如同实际上未立遗嘱而死亡的情况。

Apart from being a footnote to our beloved Jean-Jacques, this principle may allow us to build—if not elsewhere, then at least in our realm, so steeped in Fourier, Proudhon, and Blanc at the expense of Burke and Tocqueville—a social order resting on a less self-flattering basis than was our habit, and perhaps with less disastrous consequences.
