This article, from the sociological point of view, takes the whole society as a large system and the aesthetic activities of human beings as a subsystem in the society and examines the various social functions of aesthetics .

The reliability analysis of the hydro structures under flood load, thinking over the interference among the hydro structure owing to the flood's process diversion, it is supposed to reliability analysis modeling the regional hydro structures as a large system.

Container wharf is a large system, in which wharf, container yard and quayside container crane are the three most important factors, and their proper configuration will determine the handling capacity and efficiency of the wharf. .

Construction of underground project is a large system which is complicated in internal structure,contact with the external world in wide range and concludes many factors.

A large system of sparse linear and nonlinear algebraic equations is the typical form of mathematical models of process design and steady state process simulation.

However,it is not justified to find an exact solution to a large system of linear equations F′(x k)s k=-F(x k) (Newton equations) with massive work especially when x k is far from root x *.

Backward differences in time are employed resulting in a large system of nonlinear difference equations at each step.

Using the methods of statistical physics, the properties of nanostructured elements produced by breaking a large system of internal interfaces are investigated.

The reduction of transaction costs caused by the Internet will reduce the barriers to enter the market for financial products, because there may be no longer a need to run a large system of cost-intensive branches.

in which completely positive linear mappings are studied that arise, in particular, in the quantum theory of open systems, the quantum theory of measurements, and in problems of the dynamics of a small system interacting with a large system.

The optimization problem is solved by forcing causality to the Hamiltonian equations, which are produced by considering the entireN-stage process as a large system of linear equations.

This paper describes a core management system "JINEGS " to suit the development of a large system "JIGFEX"-a multiple purposed engineerin g structural analysis program. The system "JINEGS" consists of three Ievels, namely a main file, subfiles and records. The construction and functions of the system and some fundamental subroutines to realize these functions are introduced briefly. A flow chart using these fundamental subroutines are indicated.

In this paper, it is investigated how to control static compensator for improving the transient ' stability of power system in the case of a large system connected with a single machine through an external reactance. On the basis of the trajectory on the phase plane and Lyapunov' s direct method, switching line is introduced for controlling static compensator under large disturbance. A two-stage strategy controlling static compensator, consisting of nonlinear bang-bang control and linear regulation,...

In this paper, it is investigated how to control static compensator for improving the transient ' stability of power system in the case of a large system connected with a single machine through an external reactance. On the basis of the trajectory on the phase plane and Lyapunov' s direct method, switching line is introduced for controlling static compensator under large disturbance. A two-stage strategy controlling static compensator, consisting of nonlinear bang-bang control and linear regulation, is proposed. The early stage is capable of damping the oscillation most quickly, while the later will ensure that the system smoothly reach its new stable state.Digital simulation has proved that this strategy is excellently effective.

Computing the convective heat transfer in a box-type heater involves solutions of a large system of non-linear equations which contains several hundreds even thousand unknown.The difficulty in solving this system of non-linear equations is the choice of an initial value,close enough to the true solution to assure convergence. A layer to layer method is used from bottom to top to reduce the dimensions of the system. The differential continuative method which has global convergence is used to...

Computing the convective heat transfer in a box-type heater involves solutions of a large system of non-linear equations which contains several hundreds even thousand unknown.The difficulty in solving this system of non-linear equations is the choice of an initial value,close enough to the true solution to assure convergence. A layer to layer method is used from bottom to top to reduce the dimensions of the system. The differential continuative method which has global convergence is used to solve this system of equations. Computations have shown that this method is so efficient that the initial value can be chosen arbitrarily within the rang from 0℃ to 3000℃, the internalstorage required is of that used before, the least computing timeis 112 seconds and the accuracy of calculation is
