PSS/E is a power system simulation and analysis software commonly used by operational department, which is mostly applied to analyze single case based on artificial operation mode model. PSS/E application mode that API secondary development is used to simulate and control full physical model is proposed in this paper. Full model of power grid is automatically created based on CIM/E model file that...
This thesis introduces the digital esign method applied in some product, and it explains the digital design of products from the perspectives of three-dimensional modeling, CAE analysis, optimization design, and so on. This digital design method can be applied well in other engineering fields.
In this paper, analytical techniques and fuzzy logic method are applied to the dynamic modeling and efficient swimming control of a robotic fish. The bioinspired robotic fish, which follows an exact replica of a live mackerel (Scomber scombrus), is modeled by treating the undulating body and flapping tail independently using analytical methods. Comparing the results of simulations and experiments...
Firstly, this paper studies a variety of possibility of inventory in view of the system, uses fuzzy function to model the random demand system; subsequently, designs the random demand system by JAVA language and does the simulation experiment of real data. This paper mainly analyses the fuzzy algorithm and shows the simulation conclusion. That this model and system can provide decision support for...
As the increase in service level, there is necessary for D University to introduce advance management theory to improve service level. In this paper, the writer point out the problem of D University Financial Department, and use Queuing Theory and Pooling Theory to improve the service level of Financial Department of D University.
Abstract-It is designed a new fully compliant 3-RRRP parallel micro-displacement vibration actuator. All the joins in the traditional 3-RRRP parallel mechanism are changed into fully compliant ones. Theoretic analysis shows that the fully compliant mechanism will transfer into micro-displacement vibration actuator if adding single freedom PLZ vibration actuators to the traditional inputting components...
With the rapid development of the information technology and continues improving of net economy, modern manufacturing enterprises have gradually changed their business model from the traditional into Internet-based. But the traditional ERP system serviced in enterprise mainly focused on optimization of internal process of business, it also made enterprises can not exchange information effectively...
As traditional network security cannot meet the security requirements, the international research shows that network security is on the way to Trustworthy Internet and that the trustworthy issue becomes a hot topic in the future Internet. Trust evaluation of userspsila behavior is an important part of Trustworthy Internet and a rational trust model plays a key role in the evaluation. This paper concludes...
The aim of this study is based on GM(0,N) model to evaluate the biochemical factors in preterm neonates, include growth hormone (GH), insulin-like growth factors (IGFs), IGF-binding proteins (IGFBPs) and leptin, the proteins known to be involved in the regulation of growth. And find the influence for each factor corresponding with the body mass index(BMI) and postnatal growth(PI). First, we use the...
In the study of prediction filed, no matter what methods we used, the main purpose is to minimize the prediction error; however, the goals cannot be fulfilled completely. Even we choose GM(1,1) model, which in the newest soft computing method, we also need to minimize the prediction error. Hence, in this paper, we focus on the influence parameter alpha in GM(1,1) model in the first, then, analyze...
In the prediction research, the main purpose is to minimize the prediction error; however, the goals cannot be fulfilled completely. Even we choose GM(1,1) model, we also need to minimize the prediction error. Hence, in this paper, we first focus on the influence parameter alpha in GM(1,1) model, then, analyze the characteristics of alpha step by step. Second, we give up the alpha = 0.5 method, and...
