We can comprehend the REITs as a kind of trust, by which many investors’money, which will be leaved unused during one period, is gathered to set up aorganizations, whose main works is to invest money in the real estate, manage theseassets, and at the end of the investment, as the return of the money, the investorsshare the return of the investments in the real estate assets.
The theory of rough set is a new mathematical tool to deal with uncertain knowledge. Its power property is that the decision rules are determined by given data associated with reducing knowledge and analyzing dependence of knowledge without any extra prior information.
From unusual phenomenon of security market, such as Reversal Effect and Disposition Effect, decision of investor is irrational. And Set of individual investor irrational behavior cause unusual price fluctuation which increase the risk of the security market.
Fuzzy clustering algorithm is used to identified initial fuzzy model. The number of fuzzy rules is determined by cluster validity measure. Similar fuzzy sets merging method is then applied to remove redundancy of the fuzzy model to improve its interpretability.
This paper first proceeds from general definition and function of money, divide the electronic money into several different sets, distinguish the electronic money that various kinds of electronic means of payment produce essentially;
In particular, we give a detailed description of these sets in terms of cross-sections inside maximal R-tori ofH.
In some of the examples the limit sets are wildly knotted 2-spheres.
LetRo andR1 be two Kempf-Ness sets arising from moment maps induced by strictly plurisubharmonic,K-invariant, proper functions.
We investigate the sets C(S) of such x for various orbits S and their relations with each other.
Using these generating sets, we shall determine the Hilbert series of the above Freudenburg's and Daigle and Freudenburg's nonfinitely generated Ga-invariant rings, and find that these Hilbert series are rational functions.
The form of complex signals in the ensemble for radio navigation and remote control was optimized.
According to the numerical investigations, "the ensemble average coincides with the time average" in the neighborhood of the limiting set, i.e., it is sufficient to track only one path in solving optimization problems in such a system.
Selective control of the observables in the ensemble of quantum mechanical molecular systems
The canonical (T, V, N) ensemble at 25°C and Metropolis sampling technique have been used.
Expression was found for the resistance force averaged over random ensemble of fibers, which well describes the results of numerical simulation with the use of lognormal fiber radius distribution, including the case of high fiber polydispersity.
