“十二五”天津市R&D/GDP规划目标实证研究

在全国经济下行、天津经济增速趋缓的形势下,我市科技创新逆势发展,全社会RD经费内部支出突破500亿元,达到510.18亿元;RD/GDP达到3.08%,,超过"十二五"规划目标0.08个百分点;RD/GDP指标继北京、上海之后,连续9年居全国第3位。"十二五"规划科技目标圆满收官,为"十三五"科技发展奠定了坚实基础。数据同时显示,天津市科学研究经费投入偏低,滨海新区研发投入强度低于全市平均水平,高水平RD研究人员投入不足。提出要积极争取中央、市级和区县三级财政对RD活动的支持力度,落实好高企减免税和研发经费加计扣除政策。

福建省R&D经费投入现状及其对策研究

RD经费投入强度是评价科技创新能力的重要指标,也是建设创新型省份的重要因素之一。该文针对福建省RD经费投入情况,分析了经费投入构成及特征,指出福建省研发经费投入不足的原因主要是财政资金投入偏低、大院大所数量太少、企业技术创新能力不足,相应的,从增加财政投入、打造科技创新平台、强化企业创新主体地位等方面提出对策建议。     

苏州市R&D经费投入现状与分析

研究与试验发展是科技进步与社会发展的重要环节,其经费支出情况一定程度上表征了科技创新的驱动力度。根据2010年以来苏州全社会研发经费支出情况,着重分析了苏州市规模以上工业企业研发经费的投入情况,发现苏州市RD经费投入存在着全社会研发试验经费支出增速放缓、政府资金引导不够、企业研发投入自觉性不足等问题,提出了相应对策,以进一步发挥政府管理作用,调动企业积极性。     

影响山西研发经费投入的因素及对策

根据山西省近年来研发经费投入(RD)现状,分析了当前山西省研发经费投入水平较低的主要因素,提出应当从增强企业家创新意识、激励企业加大研发投入、完善多元研发投入体系、改革政府考核评价指标体系等方面提高研发投入水平,加快创新驱动战略的实施。     

甘肃省R&D经费投入结构与强度对比研究

甘肃作为西部欠发达地区的缩影,在科技创新领域创造出了"低投入、高产出"的现象。然而,在研究与试验发展(RD)经费累积量不足、企业研发投入强度落后的背景下,加之近年来受经济下行影响,出现了RD经费投入增幅下降并持续回落的迹象。本文对2000年以来甘肃省的研发经费总量、投入强度、来源结构、经费结构等进行对比分析发现,与发达地区相比,这不仅仅是数量增长,还有结构的变化,需从多方面共同发力。     

政府R&D投资经费过程监控与绩效管理

正政府和企业是RD活动经费的两大主要来源[4]。RD项目经费主要是实际用于基础研究、应用研究和实验发展的经费支出,包括科学研究和实验发展过程中的人员劳务支出、原材料费用、固定资产投入和相关的管理费用及财务费用等其他费用支出。我国政府RD投资经费的支出要求各个执行单位严格按照国家的经费使用办法,遵循专款专用的原则,确保政府的RD投资经费用在科技研发中。2006年财政部和科技部分别制定了《国家重点基础研究发展计划(973)专项经费管理

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

海南岛地体及其毗邻陆缘晚中生代—新生代古地磁研究和构造演化

本文叙述了对海南岛及其毗邻大陆边缘白垩纪到第四纪地层岩石进行古地磁研究的全部工作过程。通过分析岩石中剩余磁矢量的磁偏角及磁倾角的变化,提出海南岛白垩纪以来经历的构造演化模式如下:早期伴随顺时针旋转而向南迁移,后期伴随逆时针转动并向北运移。联系该地区及邻区的地质、地球物理资料,对海南岛上述的构造地体运动提出以下认识:北部湾内早期有一拉张作用,主要是该作用使湾内地壳显著伸长减薄,形成北部湾盆地。从而导致了海南岛的早期构造运动,而海南岛后期的构造运动则主要是受南海海底扩张的影响。海南地体运动规律的阐明对于了解北部湾油气盆地的形成演化有重要的理论和实际意义。

An on-line scaling method for improving scalability of a database cluster

The explosive growth of the Internet and database applications has driven database to be more scalable and available, and able to support on-line scaling without interrupting service. To support more client's queries without downtime and degrading the response time, more nodes have to be scaled up while the database is running. This paper presents the overview of scalable and available database that satisfies the above characteristics. And we propose a novel on-line scaling method. Our method improves the existing on-line scaling method for fast response time and higher throughputs. Our proposed method reduces unnecessary network use, i.e. , we decrease the number of data copy by reusing the backup data. Also, our on-line scaling operation can be processed parallel by selecting adequate nodes as new node. Our performance study shows that our method results in significant reduction in data copy time.     

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 the structure of R-tree, to increase the possibility of founding the satisfying answer in the front sub trees. We names this structure probability based arranged R-tree (PBAR-tree).     

Integrating GIS Web services based on mediating architecture

The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.     

Tracking data management using topology of moving object database system for moving object constrained trajectory in LBS application

Advances in wireless technologies and positioning technologies and spread of wireless devices, an interest in LBS (Location Based Service) is arising. To provide location based service, tracking data should have been stored in moving object database management system (called MODBMS) with proper policies and managed efficiently. So the methods which acquire the location information at regular time intervals then, store and manage have been studied. In this paper, we suggest tracking data management techniques using topology that is corresponding to the moving path of moving object. In our techniques, we update the MODBMS when moving object arrived at a street intersection or a curved road which is represented as the node in topology and predict the location at past and future with attribute of topology and linear function. In this technique, location data that are corresponding to the node in topology are stored, thus reduce the number of update and amount of data. Also in case predicting the location,because topology are used as well as existing location information, accuracy for prediction is increased than applying linear function or spline function.
