32-bit ARM microprocessor(S3C44B0X) is adopted to design a set of new type embedded controller for the universal material testing machine,which can improve signal processing speed and control precision of the universal testing machine.
This example makes use of the four layer system structures of J2EE, uses Apache Tomcat server, by building the connection of the JSP( the Java Server Pages) and the SQL Servers 2000 database, by applying JSP 、 EJB(Enterprise JavaBeans) 、 JDBC(Java Database Connectivity) JNDI (Java Naming and Directory Interface) and JMS(Java Message Service) technique of J2EE platform, to establish a universal dynamic websitegate system.
本实例是利用J2EE的四层体系结构,使用Apache Tomcat服务器,通过建立JSP(Java Server Pages)与SQL Server 2000数据库的连接,运用J2EE平台的JSP、EJB(Enterprise JavaBeans)、JDBC(Java Database Connectivity)、JNDI(Java Naming and Directory Interface)和JMS(Java Message Service)技术,创建了一个通用的动态的网站门户系统。
The chips of system class single chip computer C8051F020 and the network chip RTL8019AS is mainly adopted for hardware design,and the Keil Cx51 single chip high grade language is adopted for the software program,and the universal TCP/IP protocol is selected for network.

In our paper [KR] we began a systematic study of representations of the universal central extension[InlineEquation not available: see fulltext.] of the Lie algebra of differential operators on the circle.
We consider some remarkable central elements of the universal enveloping algebraU(gl(n)) which we call quantum immanants.
Let g be a Lie algebra,S(g) the symmetric algebra,U(g) the universal enveloping algebra, andZ(g) the center ofU(g).
We show that there is a complex spaceXcendowed with a holomorphic action of the universal complexificationG ofK that containsX as an openK-stable subset.
A theorem of Kostant states that the universal enveloping algebra of g is a free module over its center.
