光栅投射技术在逆向工程中的应用 总被引:1,自引:0,他引:1
Acquisition of physical data with high precision is a key step in reverse engineering ( RE). It is an important stimulative for the progress of reverse engineering with which various digitizing devices are invented, developed and made applicable. This paper introduces a three dimensional optical measurement method based on digital fringe projection technique in RE to improve the technique through its application. A practical example is presented and the result demonstrates the applicability and feasibility of the measurement system as well as the reliability and validity of relevant methods and algorithms. 相似文献

An integrated intelligent management is presented to help organizations manage many heterogeneous resources in their information system. A general architecture of management for information system reliability is proposed, and the architecture from two aspects, process model and hierarchical model, described. Data mining techniques are used in data analysis. A data analysis system applicable to real-time data analysis is developed by improved data mining on the critical processes. The framework of the integrated management for information system reliability based on real-time data mining is illustrated, and the development of integrated and intelligent management of information system discussed. 相似文献

Computer integrated manufacturing system ( CIMS ) has received much attention in many industrialized countries. Shanghai Delphi
Automobile Air Condition System Co., Ltd. (SDAAC), which is one of the large-scale key joint-venture enterprises engaged in
developing, designing and manufacturing automobile air condition system in China, was selected for implementing 863/CIMS in
1998. The experience and lessons of the developing and implementing CIMS in the last 10 years have told us that SDAAC-CIMS
is not meraly a technology exercise but an “organization revolution”. There are often much difficulties in implementing SDAAC-CIMS
simply on the traditional business system. So the contents of the SDAAC-CIMS implementation is not only technical integration
but also integration of people/organization, business processes and technologies. Therefore, several critical issues that
must be carefully considered to ensure successful implementation of SDAAC-CIMS include commitment of the top management, reengineering
of the existing processes in order to construct dynamic stable structures for aligning the SDAAC to the chaotic environment,
and integration platform of information for coping with continuously changing circumstance.

《中国教育改革和发展纲要》明确指出,要加强学校体育工作,努力提高青少年素质。而要完成这一任务,体育教师自身的素质将起着决定性作用。因为,提高青少年素质,首先需要我们的教师具有相应的知识水平和专业技能,要求他们具有先进的教育思想、教育方法和教育手段,并具有良好的心理素质和较强的自我控制能力。作为体育教师,怎样加强自身的素质修养,使自己成为优秀的人民教师,应成为我们研究并努力实践的问题。 相似文献
