An improved R-tree based on childnode''s probability

R-Tree is a good structure for spatial searching. But in this indexing structure，either the sequence of nodes in the same level or sequence of traveling these nodes when queries are made is random. Since the possibility that the object appears in different MBR which have the same parents node is different，if we make the subnode who has the most possibility be traveled first，the time cost will be decreased in most of the cases. In some case，the possibility of a point belong to a rectangle will shows direct proportion with the size of the rectangle. But this conclusion is based on an assumption that the objects are symmetrically distributing in the area and this assumption is not always coming into existence. Now we found a more direct parameter to scale the possibility and made a little change on te structure of R-tree，to increase te possibility of founding te satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).

Additional Polishing Process and the Pin-Up Speed Optimization for the Prevention of Linear Crack of BOC Chip

Introduction Chip crack,as shownin Fig.1,is one of fail-ures in many processes and it frequently happensafter Die-Attach process especiallyfor the thin die,such as BOC chip.With the development of semi-conductor package technologies,chip becomesthinner and thinner thus crack happens more andmore easily.As the volume of BOC product growsup,it is veryi mportant to find out howto preventchip against crack because a great deal devices arelost every month.Fig.1 I mages of chip crack1 Experi me…     

聚丙烯醇做土壤改良剂研究:老化与作用力分析

聚烯醇可生物分解且无毒性,可做为土壤改良剂。其在土壤中受温度、紫外线影响而老化的问题为本研究的一部份。以加热及UV处理PVA膜与PVA与SiO2混合物。样品以FT-IR光谱了解其劣化情况。PVA膜与土壤之作用力则以原子力显微镜量测其力曲线与观察表面变化。此外PVA与SiO2混合物则以SEM观察其受热与受UV处理的结果。     

过滤特征基因选择及演化硬件急性白血病分型

提出一种基于虚拟可重构结构的内部演化硬件癌症分子分型方法. 为有效处理DNA微阵列数据和便于硬件实现,对比研究了5 种基于过滤模式的信息基因选择方法. 演化硬件通过系统学习和系统分类两个阶段对经过特征选择的信息基因进行处理. 对急性白血病数据集的实验结果表明,基于信噪比信息基因选择方法的演化硬件分类器识别率最高. 演化硬件具有和其他传统模式识别方法可比的识别率,识别时间仅需0.12 ms.     

叶状蔷薇珊瑚（Montipora foliosa）断枝增殖及环境理化因子调控的研究

通过调控大型水族环境理化因子并模拟海洋生态,对叶状蔷薇珊瑚（Montipora folio sa）进行人工培育.进行了4组实验,珊瑚生长结果：M1组（1.40±0.10）cm/月、M2组（1.80±0.45）cm/月、M3组（1.50±0.16）cm/月、M4组（1.90±0.79）cm/月,平均生长速率为（1.60±0.24）cm/月.表明,该品种珊瑚能够在人工环境调控下进行较快速的生长.在本研究中,叶状蔷薇珊瑚明显比其他属种珊瑚（裸肋珊瑚等）生长速率快,可作为1个品种进行人工增殖,为自然海域的珊瑚群恢复提供物质基础和理论支撑.叶状蔷薇珊瑚被称为海底之花,其形状美丽如牡丹花、个体也比较大可作为海下旅游观览资源.叶状蔷薇珊瑚抗病力强,通过人工增殖恢复已被破坏的珊瑚生态系,能实现可持续发展的绿色海下旅游产业,服务于国际旅游岛的建设.     

A case study of WebGIS technology for distance learning between Korea and Japan

Recently, some case study of distance learning by internet line are widely carried out. Until now, the cultural or friendship exchange was a main purpose using distance learning program. In our research group, a distance learning which connected 3 sites (Nagasaki and Omura and Kagoshima in Japan) was tried as a domestic example[1]. In this case, internet exclusive line and portable telephone were utilized for DVTS technical support of distance learning. Nowadays, the international distance learning for education is also beginning. Our research group also tried international distance learning between Kwangju city of Korea and Nagasaki city of Japan using DVTS techniques with the tools of WebGIS education materials.     

爱国主体的诞生——关于第一届百花电影节中最佳男女演员的分析

本文主要探讨百花电影节最佳男女演员的身体形象。＂百花电影节＂是《大众电影》杂志社1962年创办的全国性文化活动。在此,政治领导人、编辑人员和读者凭借着对＂中国电影＂的热爱一齐创造了＂我们中国人＂的共同情感。笔者关注的是,大众的欢喜与狂热如何从服从或者反抗支配话语的层面转移到自发生产主流意识形态的层面去,也就是说,大众是如何自觉走上＂爱国主体＂之路的。     

Reduction zero-knowledge

The nature of zero-knowledge is re-examined and the evidence for the following belief is shown:the classic simulation based definitions of zero-knowledge(simulation zero-knowledge)may be somewhat too strong to include some "nice" protocols in which the malicious verifier seems to learn nothing but we do not know how to construct a zero-knowledge simulator for it.To overcome this problem a new relaxation of zero-knowledge,reduction zero-knowledge,is introduced.It is shown that reduction zero-knowledge just lies between simulation zero-knowledge and witness indistinguishability.Under the assumption of existence of one-way permutations a 4-round public-coin reduction zero-knowledge proof system for NP is presented and in practice this protocol works in 3 rounds since the first verifier's message can be fixed once and for all.
