This article analyzes the profound effects of the development of the Internet economy on modern enterprises in several aspects such as competitive means,operating models, manufacturing ways as well as organization and structure.
After analysing the the problems in the hilly grassland utilization in southern China, this paper probe the sustainable utilization strategies of grassland resource in the area from the perspective of institution, capital, operating models and environment protection which are the main restricting factors in exploiting the grassland.
The system can simultaneously acquire 8 channel data,has a sampling rate of 100 ksps for each channel and is applicable without a PC by setting two operating models of Device and Host.
N-S equation and k- ε model, three-dimensional ustructured grids, sliding net model which deals with the intervener of guide vanes and impellers, wall functions and SIMPLEC arithmetic are used in this text to simulate the inside flow of reversible axial-pump under different operating models and predict the exterior characteristic.
Starting from the development of the requirements of commercial facilities' users and the renewal of design conception, this paper emphatically analyses on the psychological requirements and behavior models of the customers and operators in purchasing and marketing activities, and points out that the design of commercial facilities can't separate from the variation of consuming behaviors and operating models, and only the consideration of the internal relation between the purchasing space and users' requirement can create the commercial facility suiting to the requirements of the times.
The principles and the actual systems of automatic alignment of the optical elements are described, as are the operating models of the automatized units.
This technology could support mass-market packet or Internet-based voice services and some operating models can be readily shifted to such a network without the customer needing to know.
Many modifications, extensions, discussions, and evaluations of chance-constrained reservoir operating models have been reported in the technical literature.
Therefore, the feelings expressed by these respondents may not necessarily reflect those of other operating models.
To utilise the value of e-business efficiently, innovative new operating models have to be developed.
It is considerable for planners to research on the theory and technique which are application of math. and computer to urban and regional planning. On this paper, according to teaching, researching and international interchange for many years, author has expounded mathematical simulation,, introduced the way selecting various operating models for urban and regional development, and put forward data managerial problems about analysing and studying of urban and regional development.
The variable speed constant frequency(USCF) electrical power system is a new type of aircraft power supply, which contains an alternating generator and a cycloconverter. This paper has summed up the work of cycloconverter, and obtained four fundamental classes of circuit construction of the closed-loop system, which have twelve operating models. The mathematical model for each fundamental class of the circuit construction has been introduced in thia paper. These mathematical models can be used...
The variable speed constant frequency(USCF) electrical power system is a new type of aircraft power supply, which contains an alternating generator and a cycloconverter. This paper has summed up the work of cycloconverter, and obtained four fundamental classes of circuit construction of the closed-loop system, which have twelve operating models. The mathematical model for each fundamental class of the circuit construction has been introduced in thia paper. These mathematical models can be used in digital simulation. The result of the simulation will be significant for the optimal design of the whole system.
This paper introduces the design and the manufacture of a new type gas discarge gun for the cathode luminescent instrument. It contains the decision of the operating model, the design of the discharge gun and the measurements of the gun performance. The experimental curves of the discharge current versus pressure at various potentials will be of great value to the people who operate the cathode luminescent instrument.
