本文引入广义G—空间的概念,讨论这类空间中映象的不动点的存在性.作为应用,我们得到了概率度量空间中映象的一些不动点定理.本文所得结果,包含引文〔2,3,6〕的一些主要结果作为特例,并在更广泛的情形下回答了或部分地回答了Rhoades〔4〕所提出的问题.     

浅谈变异修辞的解码

变异修辞拉大了辞面和辞里的距离，创造了广阔的语义空间，具有不确定性和模糊性，受话人在进行解码时，必须根据辞面运用联想才能揭示出所蕴含的深层含义。

Symmetric alteration of four knots of B-spline and NURBS surfaces

INTRODUCTION Modification of knots of a B-spline curve changes the shape of the curve. In some recent pub-lications (Juhász and Hoffmann, 2001; 2003; Hoff-mann and Juhász, 2004; Li and Wang, 2005), the authors studied the effect of the alteration of a single knot on the shape of the curve. Hoffmann (2004) and Li & Wang (2006) applied these theories into the constrained shape modification of B-spline and NURBS curves. Juhász (2001) and Hoffmann & Ju-hász (2005) studied the effe…     

Subdivision surface modeling system based on arbitrary topological curves network and combined subdivision

Arbitrary topological curve network has no restriction in topology structure,so it has more powerful representing ability in defining complex surfaces.A complex surface modeling system is presented based on arbitrary topological curve network and the improved combined subdivision method,its functions including creating and editing curve network,and generating and modifying curve network's interpolated surface.This modeling system can be used to the process of products'concept design,and its applications is ...     

Space- and time-efficient approach for virtual machine provisioning

As a new promising paradigm, cloud computing can make good use of economics of scale and elastically deliver almost any IT related services on demand. Nevertheless, one of the key problems remaining in cloud computing is related to virtual machine images, which require a great amount of space/time to reposit/provision, especially with diverse requests from thousands of users simultaneously. In this paper, by using the splitting and eliminating redundant data techniques, a space and time efficient approach for virtual machines is proposed. The experiments demonstrate that, compared with existing solutions, our approach can conserve more disk space and speed up the provisioning of virtual machines.     

Searching high gray scale FPD scanning matrix based on PSO

With the increase of gray scale and flat panel display (FPD) size, subspace bitwise scanning strategy can be replaced traditional scanning method to cut down frame frequency. However, the direct searching strategy (DSS) becomes unfeasible to obtain corresponding high gray scale scanning matrix. Thus, particle swarm optimization (PSO) is introduced to accelerate searching for high gray scale weights scanning matrix (WSM) with its parallelism and global optimization feature. Finally a WSM of 256 gray scales is found out successfully with Matlab, which both gray linearity and scanning efficiency are satisfied.     

论文学的空间存在方式

文学空间首先表现为文学作品自身的物理存在空间。文学的存在也要占据一定的物质空间,这个层面是文学作品的外围的物理存在空间。语言的空间存在方式为文学赢得了它所独有的空间性。语言本身具有空间性,并且语言和表现手法是形成空间形式的主要工具。语言创造出的空间形式又是构成文学作品结构、情节、形象的空间形式的基础,文学自身的空间性还表现在修辞格上。
