At the same time the requirement of the customers becomes mo re and more diverse and complex. The capability of the develop unit is limited b ecause of the existence of heterogeneous systems and distributed environments. I n this paper, we bring forward a new approach to solve the problem in product de velopment process. We also settle part key technologies in it. A great deal of information from all kinds of sources in the distributed develop ment process is interweaved. The solution to organize the workflow and manage th e information in the process is called for anxiously. We use a new approach that is asynchronous and synchronous coupling product development approach based on the network. The approach extends the develop process from the time axis. Then t he activities in the process are organized from the asynchronous and synchronous aspects. The state of every activity projects at the ASN (active semantic netwo rk). The ASN includes decision system, intelligent agent, user interface and net work. The ASN decides the types and states of the activities and deals with the couple relationship among them. The knowledge stored in ASN is open to all users through the relative interfaces. Every specialist keeps contact with their user s relying on collaborative platform implements CSCW (computer support collaborat ive work) that integrated product/process design and development. The lack of gl obal communication in product development process can be prevented in the most d egree. The key technologies that exist in the asynchronous and synchronous coupling pro duct develop approach include: integrated development structure, orderly organiz ation of information, transparent management of process, agile transfer of infor mation and rapid prototype. The development process can be completed quickly by these technologies. The technologies involve wide content. In this paper, we dis cuss some key technologies. We validate the approach by the projectrapid response manufacturing a pplication in the distributed environment.

The respective ratios of VIS/IR-823 am, VIS/IR-828 nm and of efficacy/VIS/IR-823 nm, efficacy/VIS/IR-823 nm are calculated to determine the behavior of the xenon excitation efficiency and the electron excitation efficiency as a function of the driving voltage and xenon content. It is found that the xenon excitation efficiency is almost independent of the driving voltage, and increases approximately linearly with the xenon content. The values for efficacy/VIS/IR-828 nm increase rapidly with the xenon content, but saturate at a xenon ratio of about 30% while, on the other hand, the efficacy/VIS/IR-823 nm values decrease continuously with the xenon content.展开更多

This is the part of the brain already present in the embryo and consists of the brainstem, hypothalamus, thalamus, and midbrain. It is also the part of the brain that operates during dreaming and deep sleep and causes the transition from sleeping to waking states, and the Upanishads state unequivocally that the self is responsible for these mental states. With the self located in the embryo brain region, an entirely new interpretation of Aristotle's De Anima is presented which parallels the Upanishads in every respect; the inner self and Aristotle's "soul" have identical functions and attributes. An Aristotelian First Principle is presented: Biology is the source of Consciousness; DNA is the source of Biology; Ergo DNA is the source of Consciousness.展开更多
