This article has carried on the simple introduction to the VAR meaning and the computational method, uses CAPM (capital asset fixed price model) to carry on the modeling to the financial property repayment, carries on the fitting using the EGARCH model to the financial property repayment undulatory property, has established the financial property risk value model. The real diagnosis analysis explanation...
This paper proposes a semantic grid structure of digital library under semantic grid environment by combining the research results of grid computing with the research o f the digital resource's semantic cooperation in digital library, and discusses the key technologies and services of digital library knowledge organization under semantic grid environment. Then not only discusses semantic notes and...
The equivalent circuit model is proposed in this paper, which is based on RC parallel networks, in order to model I–V performance and transient behavior of battery. The model consists of a series resistance, a self-discharge resistance and two RC networks. The I–V performance and transient behavior of the model are researched in time domain. Battery model efficiency is proved by frequency domain analysis...
The development and implementation of a virtual real-time roaming system is introduced. The system was to investigate hydraulic environment by analyzing large quantities of geographical-related data. Aspects like presentations of data with spatial dependence, virtual real-time roaming in the terrain and geographical frame of reference and interaction techniques are presented. Easy-to-use methods that...
In wastewater treatment plants, It's difficult to acquire online data of BOD5 (Biochemical Oxygen Demand for 5 days) due to its characteristic and unreliability of on-line sensors. Furthermore, although soft sensors models are widely used in wastewater treatment, only a few approaches for soft sensors models are designed to address the problems currently existing in the wastewater treatment. In such...
Most previous approaches to automatic audio events (AEs) annotation are based on supervised learning which relies on the availability of a labeled corpus to train classification models. However, instance annotation is often difficult, expensive, and time consuming. In this paper, we apply semi-supervised learning with transductive Support Vector Machine (TSVM) algorithm to automatic AEs annotation...
In order to better grasp the development trend and study the development path of service industry, this paper built ARIMA forecasting mode based on related statistical data from 1978 to 2008 to predict the service industry development of Sichuan Province, and analyze the forecast results.
The power performance and fuel economy are simulated under the model of THsS II based on ADVISOR software. Compared with the simulation results of Prius, the distinct advantage of THS II belonging to the double planetary gear system can be obviously found out. Test results show that: better power performance and fuel economy can be achieved by THS II than THS, which belongs to the single planetary...
The usual method of aerosol retrieval using remote sensing is interpolation of look-up-table (LUT), but it is too time-consuming. However, artificial neural network for nonlinear problem has been not applied widely for aerosol retrieval before. In this paper, aerosol optical depth (AOD) is retrieved using two methods: interpolation and neural network. Then, the retrieval capabilities of the two methods...
A dynamic data with amendments model is proposed here on the basis of the base state with amendments model. Combined with the double-database strategy which stores history data and current data respectively, the new model further becomes the double-database strategy dynamic data with amendments model. Employing this model to store and manage temporal data can effectively reduce the data redundancy...
This article seriously analyzed the work procedure of the workflow engine, proposed the overall structure and design model of the workflow engine based on the relational data model, carefully discussed the design plan of the data and process control parts of the workflow engine, and realized the flow control from the data base trigger.
A new method for global nonlinear aerodynamic model identification is presented. Aerodynamic model of aircraft is analyzed, and a simple and effective aerodynamic model is presented. The aerodynamic model of aircraft is then depicted in NARMAX (Nonlinear Auto Regressive Moving Average model with eXogenous inputs) form inside a Linear Regression framework. The items and coefficients of the aerodynamic...
Today with rapid development of computer technology, people require placing data into large databases on the unified management. And a variety of data need the corresponding efficient boundary when they need to store. The standard framing data as one of the special kinds, that how to take a fast, accurate and effective storage has been always the focus of the study. This article starts from the naming...
This paper proposed a method of adaptive neuro fuzzy inference system based on the data field to solve the drawbacks of the general fuzzy neural network that can not optimize fuzzy rules and consume too much time in optimizating networks. Initialize fuzzy inference and network structure can be determined through the data field. The neural network learning mechanism is introduced to the logical reasoning,...
Understanding of attributes of UML class diagram can be influenced by various factors. Semantic annotation for attributes can help model users understand their meaning precisely. As a result, services provided by the models can be better applied in the data processing tasks of the users. This paper proposes a method of semantic annotation of UML class diagram and provides detailed steps of implementation...
Life Cycle Assessment (LCA) is considered as an important potential sustainable development tool in 21 century. China is the biggest coal consume country in the whole world, and the coal-fired power generation is the biggest customer. Assesses environment in it with the CLA, it will improve ecological environment and the whole global macroclimate. Software design of LCA for coal-fired power generation...
