According to some basic enterprise production management,will address the gap between research and practical application of the problem and offer a solution,and the solution will be applied in single unit job lot production enterprises such as mold manufacture.
Based on the application of EST-2001A COD monitor,a solution of COD on-line monitoring system based on GPRS is put forward, which aims at the scattered position,wide distribution,and bad testing sites for monitoring.
In this paper,First we introduce the hardware of a new SPM system with the core of DSP,then program the DSP to be a digital PID controller instead of the analog PID controller for previous SPM,hence realize the digital PID control solution for SPM system.
After analysis on comparison of IEC 61850 technical protocol and existing communication protocols,along with the introduction of the existing communication system structure in the substation of Shijiazhuang Power Grid,this paper concludes that the generalization of IEC 61850 is development trend of substation′s automation system of Shijiazhuang Power Grid,and presents two transitional plans.
We use the decomposition of a group into double cosets and a graph theoretic indexing scheme to derive algorithms that generalize the Cooley-Tukey FFT to arbitrary finite group.
The new wavelets used in [23] were designed from the Loop scheme by using ideas and methods of [26, 27], where orthogonal wavelets with exponential decay and pre-wavelets with compact support were constructed.
In this prominent stage, rapid radioactive evolution and body-plan innovation have taken place and different associations of organism have been shaped.
Plan recognition, the inverse problem of plan synthesis, is important wherever a system is expected to produce a kind of cooperative or competitive behavior.
The theory is applied to the case of cubic hypersurfaces, which is the one most relevant to special geometry, obtaining the solution of the two classification problems and the description of the corresponding homogeneous special K?hler manifolds.
A necessary and sufficient geometric condition on the growth of the boundary of approximate tiles is reduced to a problem in Fourier analysis that is shown to have an elegant simple solution in dimension one.
Indeed, if the coefficients of L are in $W^{1,2}\cap L^{\infty},$ then L can be rewritten in divergence form for which the notion of a "weak" solution can be applied.
Specifically, we show that the planning graph, which is an important component of the classical planning system Graph-plan, can be used as an implicit, dynamic planning library to represent actions, plans and goals.
For their solution, methods for construction of consistent plans of operation of enterprises are suggested, which can be detailed if necessary before the schedule of processing of individual parts.
In ordinary sampled-data control systems the system response to a step input can reach its equilibrium state only within n or more sampling intervals (n is the order of the controlled plant). In this paper multiple-impulses are used, instead of ordinary simple impulses, to speed up the system response. In such sampled data systems the system response to step input can reach its equilibrium state within less than n, even one, sam-pling intervals. Methods of design of such kind of sampled-data systems and the...
This paper presents an investigation of the"Automatic Operator" of Diesel Loco-motive based on the principle of compound programming control. According to the sur-rounding conditions of locomotive, the"Automatic Operator"can change its structure automatically in order to obtain better quality of control.In this paper, the principle scheme, the characteristics of"Automatic Operator" and the experimental results of automatic control of Diesel locomotive with "Automatic Operator"are presented, the principle an...
In this paper a microwave standard noise source which produces noise by healing a metal filament is described. Its design and the measurement of effective noise tem- perature are discussed in detail. A new method for estimating the effect of losses of glass envelope and tuning elements on-the effective noise temperature is presented. The effect of the cold end of the hot filament is also quantitatively corrected. The results of the experiments and the error analysis are given. This noise source can give a s...
