Enterprise Information Engineering Model and Its Integrated Support Environment

By analyzing the process of enterprise information engineering construction and intra relationship among information system requirement, business process modeling, application system constructing and project management, one of 4 meta model composed of requirement engineering, process engineering, application system engineering and support engineering is proposed for enterprise information engineering. The developments and applications of the business processes and its application systems are integrated into the same development space and application space. Basing on this, a prototype system composed of requirement modeling environment, business process modeling environment, application system modeling environment, and support engineering environment has been designed and built, which is used for supporting enterprise information engineering constructing. It is valued for the enterprise information engineering construction in our country.

The new vibration comfort coefficient is applied to evaluate the ride comfort of automobile, and the software is developed. It is verified that the study has theoretical and practical value significantly.     

Study on Application Model of Knowledge Expression

As a key resource, the knowledge management is becoming a research field interested by many researchers. In order to study the mathematics theory base of knowledge expression, in this paper, a knowledge expression model is given. In this model the knowledge system is expressed by multi-tuple, the single knowledge object is expressed by the tuple, a structural expression of knowledge is given using token as example and the application of the model in city water supply pipe network is presented in this paper.     

Resource Management in Application System

Application system generally refers to all kinds of computer information system. It aims at improving the sharing and application of the resource. The resource in application system usually means data resource. For computer management and maintenance, there are not only data resource, but also program resource and network resource. Effective management of this resource is key to ensure proper work of the application system. In this paper, the basic pattern and policy for resource management is put forward and a method to build and realize the resource layer that lies between database layer and application layer is to be found. This management layer, which skillfully connects the application system with resource and establishes good base for application and exploitation of system, is named as resource management system.     

葡萄籽原花青素生物学功能及其在畜禽生产上应用的研究进展

原花青素是一类广泛存在于植物界的多酚化合物的总称,其中以葡萄籽的含量最为丰富。研究表明,葡萄籽原花青素(GSP)有多种生物学活性。笔者综述了GSP的清除自由基、抗氧化、抗肿瘤、降血脂等生物学功能研究及其在畜禽生产上的应用研究进展,提出了将GSP作为新型饲料添加剂以提高动物的免疫力、肉品品质和抗应激作用,为GSP进一步开发和利用提供参考。     

基于小波分析的玉米籽粒图像正形研究

近年来,通过对玉米籽粒的尺寸、外形、色泽等方面的研究,已获得了一些必要的单籽粒的视觉信息。但是,对于粮食作物而言,只有实现了作物籽粒的大规模、快速识别,才有可能在实际生产中得到广泛应用。为此,采用图像标记法,对含有众多的、散放的玉米籽粒图像进行处理,对标记图像中的像素进行逻辑判断,采用多尺度小波分析算法,实现籽粒分割、定位及正形。
