A family of binary sequences were constructed by using an elliptic curve and its twisted curves over finite fields. It was shown that these sequences possess "good" cryptographie properties of 0-1 distribution, long period and large linear complexity. The results indicate that such se quences provide strong potential applications in cryptography. 相似文献

Many practical problems in commerce and industry involve finding the best way to allocate scarce resources a-mong competing
activities. This paper focuses on the problem of integer programming, and describes an evolutionary soft a-gent model to solve
it. In proposed model, agent is composed of three components: goal, environment and behavior. Experimental shows the model
has the characters of parallel computing and goal driving.

In this paper, we have proved some special properties of singular integral operators which are transformed from the singular
integral equation defined in the interval (−1, 1), i.e., the properties of singular intergral operators at the endpoints and
in the inner of (−1, 1).

An anisotropic model of sandpile has been proposed with different topping in different directions taken in consideration.
Simulation results show that no significant differences exist between this anisotropic model and the isotropic one.

Wetlands in Jianghan plain-lake district fulfill many uses and functions related to hydrology, waste assimilation, ecosystem
productivity and bio-diversity. But human incorrect activities generally result in significant negative impacts on number,
biodiversity, and functioning of wetlands. In order to put wetland resources to rational use and protect wetland ecological
environment, some effective measures should be taken.

V. I. Arnold defined some particular classes of index for singularities of adapted fields. We generalize these index classes
for general fields on manifolds with boundary and get some relations of these index classes.

In this paper, we generalize an, inequality of meromorphic mappings to quasimeromorphic ones. Applying the results here, we
can establish a normal criterion of quasimeromorphic mappings.
