This paper discusses the improvement and enrichment of traditional classification,subject classification,integration of classification and subject classification and bibliographical control in the network environment,and systematically describes the advantages and application of the methods of in organizing virtual information resources.
Under the support of the Major State Basic Research Development Program ("973"Program) on "Study of Relevant Issues of Micrometer- Scale RF Components" of "Study of Integrated Micro- Optical-Electronic-Mechanical System" (Subject No. G1999033105), this thesis studies the theory of time-domain modeling and simulation of the micromachined antenna.
This paper discussed the theory and technology of viewpoint control completely and deeply, and put forward for the first time a algorithm of automatic viewpoint control based on target and a algorithm of optimized viewpoint control based on a subject cluster, The experiments show that, The cognitive efficiency in virtual geographical environment will be improved through the Algorithms presented by this paper.
Recent study on the subject is an indirect approach: in order to compute the Gabor coefficients, one needs to find an auxiliary bi-orthogonal window function γ.
The design that is subject to this criterion satisfies many kinds of linear optimal criterion and D-optimal criterion on several experiment models at the same time.
This paper deals with the blow-up properties of solutions to the systems ut=Δu,vt=Δv in BRX(0,T) subject to nonlinear boundary conditions , in SRX(0,T).
The reliability engineering is an important, specific problem of the system engineering and is also a new engineering subject, Using the concepts and methodology of the system engineering, it deals with the programs and techniques controlling the system reliability of varions phases during the system life cycle. This paper has pointed out that at the initiate stage of the engineering system, to control the system reliability is the basic link among all the links of the engineering, and, at this stage,...
Departing from the classifications and explanations of attributive adject- ives by Jespersen, Quirk et al. and Close, and employing the approach of“dual division and dual combination,” the writer of this paper presents some new views, comments, explanations, extensions, and supplementations to the funct- ions of the epithets, and consequently subdivides them into adjectiye of time, place, manner, degree, result, condition, concession, etc. Again. with the correlation and the specific character of contraditi...
It is a new subject for us to process stereo X-ray images with microcomputers. We have laid stress on algorithm and made simulant experiments on the Cromemco microcomputer,using the Fortran language. Now a practical procedure has been obtained.
