Design and realization of a remote monitoring and diagnosis and prediction system for large rotating

Shaohong WANG, Tao CHEN, Jianghong SUN

Frontiers of Mechanical Engineering 2010, Volume 5, Issue 2, Pages 165-170 doi: 10.1007/s11465-009-0090-1

Abstract: Traditional on-site fault diagnosis means cannot meet the needs of large rotating machinery for its performance and complexity. Remote monitoring and diagnosis technology is a new fault diagnosis mode combining computer technology, communication technology, and fault diagnosis technology. The designed remote monitoring and diagnosis and prediction system for large rotating machinery integrates the distributed resources in different places and breaks through shortcomings as the offline and decentralized information. The system can make further implementation of equipment prediction technology research based on condition monitoring and fault diagnosis, provide on-site analysis results, and carry out online actual verification of the results. The system monitors real-time condition of the equipment and achieves early fault prediction with great significance to guarantee safe operation, saves maintenance costs, and improves utilization and management of the equipment.

Holistic integrative medicine: toward a new era of medical advancement

Daiming Fan

Frontiers of Medicine 2017, Volume 11, Issue 1, Pages 152-159 doi: 10.1007/s11684-017-0499-6

Abstract:

Medicine has encountered unprecedented problems associated with changes in nature, society, and environment, as well as with new human quests for survival, longevity, and health. In the meantime, the development of medicine is facing challenges that resulted from the over-division and specialization of disciplines and the fragmentation of medical knowledge. To construct a new medical system that is more suitable for human health and disease treatment, holistic integrative medicine (HIM), which regards the human body as a holistic entity, organically integrates the most advanced knowledge and theories in each medical field and the most effective practices in various clinical specialties to revise and adjust on the basis of social, environmental, and psychological conditions. HIM is the inevitable and necessary direction for the future development of medicine. In this article, we illustrated the connotation of HIM, the differences between HIM and other medical conceptions, and the practice of HIM in recent years.

Self-generation of machining precision and its realization in lapping of super precision solid balls

ZHANG Bopeng

Frontiers of Mechanical Engineering 2008, Volume 3, Issue 3, Pages 348-353 doi: 10.1007/s11465-008-0065-7

Abstract: This paper presents the principle of self-generation of machining precision by explaining its basic concept and five necessary conditions for forming a system with self-organization capability. A self-generation system is a kind of system with self-organization capability. The self-generation of machining precision for solid balls with super precision is emphatically explained. From the viewpoint of self-organization, there are three types of systems including system 1 with the self-regulation capability, 2 with the self-determination capability of goals, and 3 with the self-organization capability. Although they are all closed loop control systems, they have different constructions and functions. Necessary conditions for achieving self-generation of machining precision are given. Establishment of the system for machining solid balls with super precision is discussed. Self-generation of machining precision for solid balls with super precision on the basis of the capability of self-removal of errors is presented. Self-generation includes the ability of self-removal of errors for solid balls, convergence of self-removal of errors, self-generation of precision, and self-generating system for the given.
