第26届世界大学生夏季运动会于2011年8月12日在深圳隆重开幕,作为本次大型赛事电力供应者,深圳供电局肩负着本届世界大学生运动会重要保供电任务,除了保证全市正常生产生活用电需求外,特别要为大运会各类比赛场馆及相关场所提供电力保障。为确保圆满完成大运会保供电的重要使命,深圳供电局在信息安全保障方面通过信息化技术手段为本次大运保供电提供了有力的技术支撑,其中基于GIS的三维可视化系统的应用则是利用了其独特的空间分析优势,通过对保供电设备进行三维建模及立体展示,同时结合电网实时数据、气象等信息进行综合展现,从而为本次大运保电提供了强有力的信息化支持手段。     

3D打印技术“峡谷”跨越影响因素研究

基于技术采用生命周期"峡谷"理论,从市场、技术、产品和消费者维度对3D打印技术"峡谷"及跨越影响因素进行探讨。通过问卷找到现实和潜在用户,由现实采用者判断当前该技术处于"峡谷"左端,用户以企业、政府为代表,潜在采用者是"峡谷"右端早期大众市场用户代表,是跨越"峡谷"的关键。进一步对潜在采用者分析发现"技术派"最有可能成为"峡谷"跨越的早期大众市场中的单一缝隙市场,"实用派"是进一步可扩展的细分市场。     

西藏半干旱区三种柏树抗旱性研究

本文以西藏半干旱区分布的柏树为实验树种,采用盆栽控水干旱胁迫手段,比较和分析了3种柏树在持续水分胁迫条件下的生理响应,结果表明:①随着干旱胁迫时间推移,土壤含水量不断降低,各树种叶片水分饱和亏缺值持续上升,初期失水速率基本相同,至13d,各树种失水速率逐渐加快并产生差异,其中,巨柏失水速度最快、大果圆柏次之、香柏最小;②从叶绿素a+b值和叶绿素a/b值综合比较来看,香柏和巨柏的抗旱适应性、喜光性略高于大果圆柏;③遭受干旱胁迫后,巨柏、香柏和大果圆柏体内游离脯氨酸含量分别增加了68.73%、63.61%和47.66%;④在此过程中,各树种体内丙二醛含量基本保持相对稳定状态,胁迫后期与前期相比并没有出现大量积累的现象。不同胁迫阶段,大果圆柏的电解质外渗率处于较高水平,巨柏次之,香柏最低;⑤可溶性糖积累过程中巨柏和大果圆柏增量明显高于香柏;⑥随着干旱胁迫时间延长,3个树种体内保护酶SOD和CAT含量均有所下降,试验初期至结束,SOD活性分别下降了20.34%～39.35%,CAT活性下降了58.39%～72.30%。采用模糊数学隶属函数法对3种柏树抗旱性进行综合评价,其抗旱能力强弱排序依次为香柏巨柏大果圆柏。

Openness and innovation—Home and export demand effects on manufacturing innovation: Panel data evidence for Ireland and Switzerland

Recent studies in the tradition of Schmookler have re-emphasised the potential role of demand in stimulating innovation. Here, we reconsider the role of ‘home’ and ‘export’ market demand in stimulating manufacturing innovation using comparable panel data for two small open economies - Ireland and Switzerland. Our analysis is based on the estimation of reduced form innovation production functions using panel data estimators over the sample period 1994-2005. For a range of innovation indicators, however, we find little evidence of any significant market demand effects, with innovation performance instead determined largely by firm-level capability effects and characteristics. In policy and strategy terms this suggests the continued value of measures to improve innovation capability regardless of market demand conditions. In more methodological terms our results suggest the validity of the usual assumption implicit in modelling innovation outputs that supply-side factors predominate.

三维图像重建中差异信息融合算法研究

针对三维图像重建中的差异信息融合算法识别率较低,稳定性差,无法有效处理不确定因素等弊端,提出一种新的三维图像重建差异信息融合算法,分析了二维图像和三维图像的一阶与二阶统计,对自相关函数进行归一化处理,将二维图像的自相关函数变成三维自相关函数,利用傅里叶变换求出三维图像的功率谱,通过调整合理的辐角塑造该三维图像的傅里叶转换。对三维图像重建过程中的特征向量进行划分,保证三维图像重建过程中全部信息的完整性。依据特征向量与信息之间的经验知识对学习样本进行建立,给出某一时间段内三维图像重建中某个神经网络对应的差异信息融合公式,对多个神经网络的差异信息融合结果进行融合,实现三维图像重建中差异信息的融合。仿真实验结果表明,所提算法具有很高的有效性。     

R&D co-operation and innovation a microeconometric study on French firms

The scope of this paper is to report new empirical evidence on the determinants of R&D co-operation. Indeed, the literature on the capabilities of firms emphasises the role of knowledge in the performance and evolution of firms who use knowledge developed in others to build their own knowledge capital. R&D co-operation between firms is one of the many strategies by which this knowledge may be transmitted. Several theoretical models have stressed that R&D co-operation is more likely when the level of spillovers is high. While this supposition is used in many theoretical models, it has rarely been tested before. Our results do not lend strong support to this intuition. Indeed, our spillover variables (national pure spillovers, national rent spillovers and imports of machine tools), which were supposed to match the theoretical notion of spillovers used in these theoretical models have a positive but not a significant role when explaining R&D co-operation. The R&D co-operation increases with size and with R&D intensity, but not with market share. It also increases with the budget spent on paying license fees and on acquiring patents and labour from foreign firms. In this study, we also analyse the determinants of innovation. In more precise terms, we compare the effects of R&D co-operation to those played by traditional internal factors and those exerted by external, pure and rent spillovers on the innovation capacity of the firms. Our results show that the commercial success of innovations of French firms depends mainly on size, market share, R&D intensity and human capital. Inward FDI from industrialised countries exerts a positive and significant effect. The finding highlights the important role of the absorptive capacity of firms. Spillover measurements, such as the acquisition of machine tools, foreign patents, licenses, and technological opportunities have a positive impact on innovation.
