they are not seeking truth or elegance, just a way of capturing the behaviour of a market and of linking an unobservable or illiquid price to prices in traded markets.
the concepts of decentralized controllable subspace and unobservable subspace are presented.
提出了大系统的分散能控子空间和分散不能观测子空间的概念。
by analyzing selection, implementation and result of the contracts, this paper finds that the principal tends to make contracts unobservable or provide more similar contracts.
in this paper, an impulsive controllable subspace and two impulsive unobservable subspaces, the impulsive controllability and observability of singular systems are redefined from a new point of view.
本文重新定义了奇异系统的脉沖能控性于空间、脉沖不能观性子空间及脉沖能控、能观性。
the war and the killing assume a different form: they have been shifted from the daylight of observable public events, to the twilight of unobservable inner destruction.
with no decomposition of the system, some basic controllable subspaces and unobservable subspaces in singular systems are given directly in closed form by the original parameters of the system.
在不分解原系统的情况下,用原系统参数直接给出了诸能控性、不能观测性子空间的表达式。
based on concluding the computation flow of lunar gravity field recovery, the method of dealing with the difficulty of unobservable to farside of lunar are analyzed on emphases.
data leads us to regain unobservable truth despite violation of sense and intuition, while story constructs orders and meanings against complex and chaotic data.
it was simply an unobservable collection of gelatin molecules, the inner workings of which were not yet understood.
它仅仅是一种难以察觉的凝胶分子,而其内部运作则不被人们所了解。
according to most cosmological models there is a cosmic horizon outside which galaxies recede from us with velocities larger than that of light, and which are therefore unobservable even in principle.
