丁广义割圆序列的线性复杂度

Minimal polynomials and linear complexity of binary Ding generalized cyclotomic sequences of order 2 with the two-prime residue ring Zpq are obtained by Bai in 2005. In this paper, we obtain linear complexity and minimal polynomials of all Ding generalized cyclotomic sequences. Our result shows that linear complexity of these sequences takes on the values pq and pq-1 on our necessary and sufficient condition with probability 1/4 and the lower bound （pq - 1）/2 with probability 1/8. This shows that most of these sequences are good. We also obtained that linear complexity and minimal polynomials of these sequences are independent of their orders. This makes it no more difficult in choosing proper p and q.     

MINIMAL ELEMENTS IN THE POSET OF GRAPHICAL SEQUENCES

A noninereasing sequence π of n nonnegative integers graphical is graphical if it is the degree sequence of some simple graph G of order n. All graphical sequences of length n with even sum 2m and trace f forms a poset Gn, m,f under majoriztion relation. In this paper, we characterizc the minimal elememts in Gn, m, f and determine the numbers of minimal elememts in various posers of graphical sequences.     

关于Orlicz-Bochner序列空间的一些注记

In this paper, we discuss some basic properties of the Orlicz-Bochner sequence space lM (X) and its subspace hM (X). We present the equivalent definition of hM (X), the sufficient and necessary conditions under which l(M) (X) is complete, and lM (X) and hM (X) are separable respectively, and also give the sufficient condition that hM (X) has a basis. All these results generalize the results for the classical Orlicz sequence spaces.     

A Study on Students'''' Resistance in the ESL Classroom

1.Introduction In the course of teaching, teachers are sometimes conscious of the hostility hidden behind silence of some students. While there may be different levels of this hostility, it surely will cause some obstacles to the teaching activity. Here these students keep silent to show their resistance. This paper mainly focuses on students' resistance psychologically. Through the anal- ysis of the causes of their resistance, we hope a teacher can learn how to judge his class. How we teach …     

INITIAL AND BOUNDARY PROBLEMS FOR CERTAIN NONLINEAR DEGENERATR PARABOLIC SYSTEMS

In this paper we are concerned with the following nonlinear degenerate parabolic systems u_t=△x(gradψ(u))+D_xb(u)+f(x.t.u)with Dirichlet boundary conditions,where u,gradψ(u),b and f are vector valued functions and xUnder some structure conditions on the terms of the systems,we have established theresults on existence and uniquence of global solutions of the systems.     

The Employment of Symbolism in The Dubliners

The Dubliners is a famous novel by the eminent Irish novelist James Joyce.This book collection begins with new-born life and ends with death.The unity of form and content symbolizes the life process of a human being-from birth to death,there fore we can say that Dubliners is the image of a human being.In this collection,Joyce employs several kinds of symbolic method and symbols play a very important role in the implied meanings of these short stories.     

线性定常系统稳定度的判据

There are various applications of the stability theory of the first-order dynamical systems. And the stability of the non-linear control systems can be determined by its linear part. In practice, it is not enough to know the stability of the dynamical systems. Sometimes we must know the degree of stability of these systems. In this paper, we present some criteria for the degree of stability of the linear constant systems, by using the entries of the coefficient matrix A only.     

Some optimal dividend problems for a surplus process with interest

We derive some results on the dividend payments prior to ruin in the classical surplus process with interest. An integro-differential equation with a boundary conditions satisfied by the expected present value of dividend payments is derived and solved. Furthermore, we derive an integro-differential equation for the moment generating function, through which we analyze the higher moment of the present value of dividend payments. Finally, closed-form expressions for exponential claims are given.

A Brief Analysis of the Strategy to Improve the Listening Comprehension Part in SCET-3

As we know,SECT-3 is an important means to test the English language ability of a student who is not an English major in the vocational schools in Sichuan province.Of all the parts in the SCET-3,the majority of students think that the listening comprehension part is the most difficult one.There are some ways to tackle these problems in the listening part.By comparison and analysis of these questions appeared in the past few years,some regular patterns can be found.Different strategies can be used to solve different questions of each section in the listening comprehension part,so that students will feel easier in passing the SCET-3.     

Generalized cone-subconvexlike set-valued maps and applications to vector optimization

The definitions of cone-subconvexlike st-valued maps and generalized cone-subconvexlike set-valued maps in topological vetor spaces are defined by using the relative interiors of ordering cone.The relationships between the two classes of set-valued maps are investigated.and some properties of them are shown.A Gordan type alternative theorem under the assumption of generalized cone-subconvexlikeness of set-valued maps is proved by applying convex separation theorems involoving the relative interiors in infinite dimensional spaces.Finally a necessary optimality condition theorem is shown for a general kind of set-valued vector optimization in a sense of weak E-minimizer.     

Let's Do Something for Our Mothers

Mother's Day is coming soon.As a child,I think we should do something useful for our mothers and make them happy. One of the ways to celebrate Mother's Day is to give our mothers a day off.Let them relax while the rest of the family are doing the housework.Firstly,we should send our mothers some flowers or special small presents and say "Happy Mother's Day" to them.Secondly,we should do some housework,such as washing the dishes,cleaning the room and washing the clothes.We can also tell some jokes to our mothers and tell them something interesting in our school.I think these things can make our mothers happy.Finally,we should cook delicious food for our mothers.It's important for the whole family to have dinner together,because it will make our mothers feel happy.     

On the Symbols in Kafka’s The Metamorphosis

Kafka indicates the alienation of people in modern society through an absurd story. The protagonist Gregor Samsa becomes a huge beetle and finally is deserted by his family. Kafka has not followed the traditional writing style, but employs many symbols to deepen the theme. In The Metamorphosis, characters, items, scenes and actions all have symbolic meanings. We will analysis the deeper meanings of these symbolic images.     

Transitivity and Sensitivity on Uniform Maps

I.et （X,d） be a metric space and fn ： X→X be a sequence of continuous maps that converges uniformly to a map f. In this paper, we investigate the conditions that the uniform map f has transitivity and sensitivity from the viewpoint of family. We obtain that a equivalence condition for the uniform map f to be -transitive, and a equivalence condition for the uniform map f to be .P-sensitive when X is a compact metric space, where is a collection of subsets of Z＋ that is hereditary upward. Our results improve and extend the existing results. Moreover, we give a example which shows that the several results in [8] are all wrong.     

Local Lyapunov Exponents and characteristics of fixed／periodic points embedded within a chaotic attractor

A chaotic dynamical system is characterized by a positive averaged exponential separation of two neighboring trajectories over a chaotic attractor. Knowledge of the Largest Lyapunov Exponent λ1 of a dynamical system over a bounded attractor is necessary and sufficient for determining whether it is chaotic (λ1＞0) or not (λ1≤0). We intended in this work to elaborate the connection between Local Lyapunov Exponents and the Largest Lyapunov Exponent where an altemative method to calculate λ1has emerged. Finally, we investigated some characteristics of the fixed points and periodic orbits embedded within a chaotic attractor which led to the conclusion of the existence of chaotic attractors that may not embed in any fixed point or periodic orbit within it.

Collapsibility of odds ratios for a continuous outcome variable

The sign of an association measure between two varibles may be strongly affected and even be reversed after marginalization over a backgruoud variable, which is the well-known Yule-Simpson paradox.Odds ratios are strongly collapsible over a background variable if they remain unchanged no matter how the background variable is partially pooled.In this paper, we firstly give some definitions and notations about odds ratios between a dichotomous explanatory variable and a continuous response variable.Then, we present conditions for simple collapsibility of odds ratios.Further, necessary and sufficient conditions are given for strong collapsibility of odds ratios for continuous outcome variable.     

Carbon-emission calculation of electromechanical energy consumption of different structures during the construction phase

Due to the use of mechanical and electrical equipments in different buildings during construction phase, energy consumption produces large amounts of carbon emissions.Based on the energy use of China, we established a formula that was applicable to carbon-emission calculation, and discussed carbon-emission characteristics of concrete structures and steel construction.Owing to the difference of electrical and mechanical equipment used in construction phase, the results show that under the same conditions, the carbon emission intensity of a concrete structure building is much higher than that of a steel building.At last, we also put forward some emission reduction measures based on the calculation data of different buildings.
