技术转移对我国制造业企业创新绩效的影响

分别对高新技术企业与一般工业企业、大型企业与中小型企业进行了对比分析，发现高新技术企业比一般工业企业更有吸收能力，而技术转移对中小企业的影响比大型企业大。对参与技术转移及未参与技术转移的制造业企业进行了比较研究，结果证明有技术转移行为的企业具有更优的创新绩效。     

Display reflectance: Basics,measurement, and rating

Abstract— In this paper, methods and instruments for measurement and evaluation of reflection characteristics are reviewed as needed for research and development of electronic displays and for material and surface modeling with ray‐tracing and rendering software packages. Contrast under ambient illumination and recognizability under daylight illumination are prime development targets in the electronic‐display field, while computation and synthesis of realistic scenes and objects are pushing the need for physical data in computer graphics applications. Three categories of instruments are available for detailed reflection analysis. They are based on (1) gonioscopic (mechanical) and conoscopic (optical) directional scanning, (2) imaging approaches, and (3) on arrangements with variable source or receiver aperture. The capabilities, advantages, and limitations of these methods are introduced and discussed in order to facilitate appropriate selection of methods and instruments. For illustration purposes we present typical results obtained from commercial electronic display screens. A basis for continued widespread implementation and standardization of reflection metrology as required for objective rating and comparison of electronic‐display screen performance under ambient illumination is provided.

基于相关性的人机系统可靠性模型

本文在剖析人机系统中操作者行为特征的基础上,考虑到操作者行为的自适应性、自学习能力及其行为形成主因子,着重结合操作者行为的相关性-感知作用于判断决策后影响到动作,建立了人机系统中操作者行为模式,并推导出计算操作者可靠度的公式,求出了相应参数.最后进行了实例量度,同时定量辨识了行为相关性对人可靠性的制约程度,以期从人机系统可靠性角度为人机系统的优化设计提供新的依据.     

A Constraint-based Approach for Annotating Music Scores with Gestural Information

The physical gestures that operate music instruments are responsible for the qualities of the sound being produced in a performance. Gestural information is thereby crucial for a model of music performance, paired with a model of sound synthesis where this information is applied. The highly constrained nature of performers gestures makes this task suitable to be modeled via a constraint-based approach, coupled with a strategy aimed at maximizing the gestural comfort of performers. We illustrate the problem representation, the search strategy and a validation of the model against human performance.     

Addition of pectolytic enzymes: an enological practice which improves the chromaticity and stability of red wines

Summary The effect of the addition of four commercial pectolytic preparations on the visual characteristics (colour and turbidity) of red wines has been evaluated. The effect of both clarifying and colour extracting enzymes and the effect of different doses used, were evaluated and compared. All the red wines treated enzymatically, independent of the type of enzyme and dose, present chromatic characteristics which can be considered better than those of the control wines. Also, those wines treated with enzymes had greater stability during 2 years storage in bottles, in particular the turbidity was better than untreated wines.
