高等职业技术教育改革与企业创新型人力资源培育

1企业创新的重要性及其内容1．1企业创新的重要性著名的管理学家德鲁克于1954年在他的著作《管理实践》中写道：“由于企业的目的是顾客,所以企业有两个——也只有两个基本功能：创新和营销。”在二十世纪五十年代,德鲁克就已经把创新看作是企业的两个基本功能之一,可见创新对于企业的重要。     

论反讽的语用功能

反讽既是一种常见的修辞,又是交际中一种常见的语言现象。反讽正受到越来越多的哲学家、心理学家和认知科学家的关注。本文从语用学角度分析反讽,用格赖斯的合作原则和利奇的礼貌原则解释了反讽,并结合实例分析了反讽的讽刺功能、礼貌功能、彰效功能和幽默功能。

基于两级扫描线优化的快速立体匹配算法

通过引入视差梯度理论,提出了一种弱连续性约束,它表示相邻点的视差变化总在一定的范围之内.同时引入了一种两级扫描线优化方法,它从水平和垂直两方向进行扫描线优化.最后把弱连续性约束与两级扫描线优化方法结合起来得到一种快速立体匹配方法.通过对比实验表明,与未加入弱连续性约束的两级扫描线优化算法相比,所提算法计算量更少,同时减轻了同纹理区域的匹配不确定性;与传统一维扫描线优化算法相比,该算法具有更高的匹配准确性并解决了扫描线间的不连续性.

HOW ARE PRODUCT-SERVICE COMBINED OFFERS PROVIDED IN GERMANY AND ITALY？ ANALYSIS WITH COMPANY SIZES AND COUNTRIES

A new business concept that offers products and services in a different way of traditional product-sales businesses is getting more attention especially in manufacturing industries. This paper investigates how this new business by means of integration of products and services is achieved in Germany and Italy. In addition, it analyzes the differences according to the company sizes. The results include that this type of business is in many cases motivated by their focus on customers and often consists of physical products and their maintenance. The Italian companies, as opposed to the German ones, often design their physical products specifically for this type of offers. From the analysis based on the size difference, small companies are found to achieve specific design for this type of offers while owning physical products. There do not seem to be any established methods or tools developed to support the development of such offers and within such methods/tools there would be room for more adaptation in form of physical product design.     

Krylov subspace method based on data preprocessing technology

The performance of adaptive beamforming techniques is limited by the nonhomogeneous clutter scenario. An augmented Krylov subspace method is proposed, which utilizes only a single snapshot of the data for adaptive processing. The novel algorithm puts together a data preprocessor and adaptive Krylov subspace algorithm, where the data preprocessor suppresses discrete interference and the adaptive Krylov subspace algorithm suppresses homogeneous clutter. The novel method uses a single snapshot of the data received by the array antenna to generate a cancellation matrix that does not contain the signal of interest （SOI） component, thus, it mitigates the problem of highly nonstationary clutter environment and it helps to operate in real-time. The benefit of not requiring the training data comes at the cost of a reduced degree of freedom （DOF） of the system. Simulation illustrates the effectiveness in clutter suppression and adaptive beamforming. The numeric results show good agreement with the proposed theorem.     

Rough function model and rough membership function

Two pairs of approximation operators, which are the scale lower and upper approximations as well as the real line lower and upper approximations, are defined. Their properties and antithesis characteristics are analyzed. The rough function model is generalized based on rough set theory, and the scheme of rough function theory is made more distinct and complete. Therefore, the transformation of the real function analysis from real line to scale is achieved. A series of basic concepts in rough function model including rough numbers, rough intervals, and rough membership functions are defined in the new scheme of the rough function model. Operating properties of rough intervals similar to rough sets are obtained. The relationship of rough inclusion and rough equality of rough intervals is defined by two kinds of tools, known as the lower （upper） approximation operator in real numbers domain and rough membership functions. Their relative properties are analyzed and proved strictly, which provides necessary theoretical foundation and technical support for the further discussion of properties and practical application of the rough function model.
