In this paper, a nonlinear semiquantum Hamiltonian associated to the special unitary group SU(2) Lie algebra is studied so as to analyze its dynamics. The treatment here applied allows for a reduction in: 1) the system’s dimension, as well as 2) the number of system’s par.m.ters (to only three). We can now discern clear patterns in: 1) the complete characterization of the system’s fixed points and 2) their stability. It is shown that the par.m.ter associated to the uncertainty principle, which constitutes a very strong constraint, is the key one in determining the presence of fixed points and bifurcation curves in the par.m.ter’s space.

Journal of Agricultural Science and Technology(B) 2011年第4期1卷 463-472页

The agri and food industry is a major industrial sector in Denmark. Compared to other countries on a similar level of economic development Denmark has an extr.m.ly important agriculture and agribusiness sector. Danish agri and food cooperatives seem to have been successful in obtaining international competitiveness. The transformation and the structural development of the cooperative sector have more or less been completed. The development of the industrial structure among Danish agricultural cooperatives has been very rapid during the latest decades. Through mergers and acquisitions the number of firms has fallen dr.m.tically, and the result has been increasing concentration ratios in almost all groups of the food industry. Structural development, concentration and globalization in recent decades have resulted in agri and food companies now being among the largest in Europe. To a large extent, agriculture all over the world faces similar problems and challenges. For this reason, it is essential that know-how, experiences and lessons can be transferred and adopted by agriculture in other countries around the world. In many ways, the experience and the success behind Danish agriculture and agribusiness can be transferred to other countries. However, profound studies of specific needs and conditions are necessary.

现代作战飞机对数据处理能力提出了大量的要求。为了满足这种要求,机载系统结构日益需要有多种用途的高可靠、高性能的分布处理节点。这些处理节点采用超高速集成电路/超大规模集成电路(VHSIC/VLSI)器件和表面安装工艺进行高度集成化和模块化设计。本文所述的Unisys/AT&T通用处理部件(GPPE)模块就是这种处理节点的具体实现,它可广泛应用于航空电子系统。 GPPE采用下一代简化指令系统计算机(rISC)微处理机技术,mIPS计算机系统公司的32位指令系统结构(ISA),工作频率为33mHz。该模块采用商用ISA和开放型系统结构,单宽度SEm-E军用模块的功能齐全极为经济有效。它还能让用户买到所需的开发工具。 GPPE还有多层数据安全机制和保护分类数据的多种特点。GPPE所用的6mB Sr.m.512KB的EEPr.m.合大型rISC寻址空间和实时操作系统的要求。网络总线(N总线)底板接口为分布处理环境中的模块间通信提供低开销的报文传送协议和宽带的通路。GPPE能够支持联合综合航空电子系统工作组(JIAWG)二级维护概念。模块上的维护控制器通过双测试与维护总线(Tm总)端口支持模块状态信息的操作报告。单个联合测试功能组(JIAG)接口支持基地测试和若干机内自测试方法都综合在模块上,有很高的故障复盖率和测试可信度。 GPPE适用于要求性能?
