Particular Solutions of Generalized Linear Second Differential Equations by Fractional Calculus

本文依据Ｋ．Ｎｉｓｈｉｍｕｔｏ教授于１９７９年所定义的分数微积分定义Ｌｅｍｍａｓ为基础,给出一种线性阶微分方程及偏微分方程（包括均匀及非均匀）的方法,使其更一般化,概括范围更宽、更广．     

高等数学(上)的要求与例举(1)

高等数学(上)——一元函数微积分,包括函数与极限,一元微积分,级数与常微分方程共八章。今年是理工类高等数学新教学计划第一年。这次的高等数学课体现了教学大纲要求,符和理工类的大专高等数学的基本理论、基本技能、基本运算的要求,更突出了数学的实用性,如讲授曲率、近似求解和物理应用等。由于内容较多,又是第一次实行,师生们对这个课总是较关注的。为此,本文指出学习的重点内容,供同学们参考。     

分数阶微积分在现代信号分析处理中的应用

分数阶微积分在现代的信息科学中开始出现基本应用,近年来随着分数阶微积分理论和应用的成熟,其在现代信号处理中做出了优秀的表现,例如强化信号等等。本文在阐述了分数阶微积分相关理论的基础上,对分数阶微积分的工程应用做了归纳,分析了现代信号处理中的相关分数阶微积分实现理论,最后阐述了图像信号的分数微积分实践应用,为分数阶微积分的信号处理应用提供一定的借鉴意义。     

均匀磁化球体的磁场

求解均匀磁化球体内外的磁场分布问题,通常是求解Laplace方程,在普物《电磁学》阶段,可利用类比方法,从磁荷观点出发,巧妙运用“错位叠加法”求解,对解决其它类似问题有很好的借鉴意义.

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

Western and Eastern culture differences in commercial field

The communication of people partially is the communication of cultures. Culture has a direct effect on international commercial activities in all aspects. Different conceptions about time, space, equality, law and the like, lead people to deal with things in different ways. So to know cultures of the counterpart is to facil-itate our enterprises so as to have a smooth and successful communication in commercial activity.     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.

团图为数的图中的闭团贯数

Given a graph G,a subgraph C is called a clique of G if C is a complete subgraph of G maximal under inclusion and |C|≥2. A clique-transversal set S of G is a set of vertices of G such that S meets all cliques of G. The clique-transversal number, denoted as TC (G), is the minimum cardinality of a clique-transversal set in G. The clique-graph of G, denoted as K (G), is the graph obtained by taking the cliques of G as vertices, and two vertices are adjacent if and only if the corresponding cliques in G have nonempty intersection. Let F be a class of graphs G such that F={G|K(G) is a tree}. In this paper the graphs in F having independent clique-transversal sets are shown and thus TC (G)/|G|≤1/2 for all G ∈ F.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.
