Using computers to conduct human body simulation experiments (e.g., human sport simulation, human physiology simulation, and human clothing simulation) can benefit from both economic and security. However, the human simulation experiment usually requires vast computational resources due to the complex simulation model which combines complicated mathematical and physical principles. As a result, the simulation process is usually time-consuming and simulation efficiency is low. One solution to address the issue of simulation efficiency is to improve the computing performance of the server when the complexity of the simulation model is determined. In this paper, we proposed a concurrent optimization scheme for the server that runs simulation experiments. Specifically, we firstly propose the architecture of the server cluster for the human body simulation, and then we design the concurrent optimization scheme for the server cluster by using Nginx. The experiment results show that the proposed concurrent optimization scheme can make better use of server resources and improve the simulation efficiency in the case of human sport simulation.

The paper is aimed at the calculation of the throwing parabola of material particle and its graphical interpretation by changing input parameters selected according to predefined requirements. The aim is to compile a complex simulation model and comparison of the obtained simulation results on the model with analytical calculation. Simulation experiments on the model confirmed the known dependence of the change of throwing parabola by increased speed and retention of the radius of the staging drum. The simulation model was created in the program MSC Adams/View – a tool for easy construction and visualization of the model and convenient evaluation of the obtained results.

In order to manage the complex simulation data management in the process of mechanical dynamics simulation, a new management model was presented which is Performance Simulation Model(PSM). The model was based on PDM product structure and the concepts and elements of PSM were defined in this paper. Furthermore, the functional framework of PSM was proposed which based on the hierarchical relationship of product structure and the data stream relationship of data structure matrix. Finally, PSM was applied on ship planetary reducer collaborative simulation platform. The result indicates that the simulation data in mechanical collaborative simulation are managed by PSM, and the problem of interaction between collaborative simulation and PDM is solved.

Monte Carlo Simulation Model

The provision for producers to update base acres and payment yields in the 2002 farm bill afforded an opportunity to test whether it was feasible to deliver a complex simulation model directly to producers. A Monte Carlo simulation model for assessing the economic impacts of the alternative base and yield options on individual farms was developed and made available to producers via the World Wide Web. The experiences and challenges from this collaborative extension and research effort are described, as well as the issues educators might consider before delivering complex software to a national audience via the Web.

As people enter the 21st century, energy problems become one of the important restriction factors which have great influence on sustainable development of human society. So how to develop new energy and effectively use new energy is an important problem which we must face. Under the simulation environment of Matlab/Simulink, the simulation model of the whole system is established, simulation experiments are made on the designed main circuit and control system to test the design. In addition, photovoltaic array simulation model is established to test the performance of the system using perturbation observation MPPT control algorithm.

In order to validate the performance of the AMT (Automated Mechanical Transmission) control system by simulation experiment, a simulation model that can express the dynamic characteristic of the automotive power system during every phase of the vehicle driving process based on the finite state machine was proposed. Then a hard-in-loop half-real simulation system was established taking the simulation model as kernel. It was shown by the results of simulation experiments that the model could simulate the automotive power system effectively and could be used to evaluate the AMT control system.

Working Principle

When using simulation experiments in classes, it sometimes happens that students, after creating a simulation model, execute the simulation in order to verify the behaviour and working principle of an electronic circuit, but find that the outputs are completely different from the theoretical assumptions. The problem hardly ever lies in the model being erroneously assembled, but is usually caused by the simulation being run with default initial conditions whose suitability has not been verified with regard to achieving the intended educational objective. The same situation is also experienced by teachers using simulations of electronic systems in their classes. The situation described above can negatively influence secondary-school students' attitude towards computer simulations and give the false impression that simulations do not work well. The aim of this article is not only to warn teachers and others interested in simulations of electronic circuits about such a situation, but also to demonstrate its possible solution with an illustrative example.
