Considering that freeway mainline has not only high speed but also the ability to store large amount of vehicles, this research proposed a new approach for controlling both freeway on-ramp and mainline. Based on local ramp metering strategy ALINEA, this approach controls both on-ramp vehicles and mainline shoulder lane vehicles according to real-time traffic condition of the ramp and mainline so that...
To explain how to use VRML in virtual city construction, the authors review main characteristics of virtual city, assess a number of effective programming languages applied on the Web 3D, discuss the basic functions of VRML and the basic frame of virtual world based on VRML, give an application instance of virtual city scene and show a lot of experiences. In the case study, Cortona VRML Client plug-in...
Aiming at the shortcomings of the BP neural network, this paper presents a method for grain condition information fusion based on BP neural networks and D-S evidential theory. This method firstly employs many BP neural network outputs as the inputs of D-S evidence theory. After that, D-S evidence theory is used to fuse with results from all the neural networks, resulting in the grain quality evaluation...
Support vector machine has some advantages, such as simple structure and good generalization, which is one implementation in statistical learning theory. SVM offers a kind of effective way for the data fusion problem of little sample, non-linear and high dimension. In this paper, mobile agents are applied to data fusion system. The model and the study method of data fusion system are improved. An...
This thesis takes three approaches in strategic sense respectively: Call, put and hold. First of all, it collects daily information and relevant factors which could influence the stock price one day ahead of the actual trading for China Steel stocks. These factors include aspects in the stockpsilas fundamental, share volume, technical performance in addition to Dow Jones average plus processing these...
Business process model and data model play important roles in information system construction. They represent two different perspectives of business knowledge, and are closely related. A trouble to the model quality is the inconsistency between business process model and data model, which can often conduce to interaction errors. While finding such inconsistency is a meaningful problem, it receives...
Campus networkpsilas Internet accessing traffic is complicated, non-linear and periodical. Our goal is to give out a engineering approach to prediction of network traffic based time-series analysis model (EPTS) for campus exit-link. In our EPTS with rate-limiting, we configure rate limit based interface, then use time-series decomposed model, give out the linear trend component, periodical component,...
As rapid development of economy and people's gradually great attention to energy environmental problems, more and more researchers have started researching the relationship between economy, energy and environment, we urgently need methods and models to solve the disagreement between them, and so 3E-based forecast and early-warning models began to emerge, and develop towards high-precision and comprehensive...
Not each partner enterprise of virtual enterprise will share its private data with other enterprise, so there is a conflicting problem of data exchange in virtual enterprise. To solve the problem, a data exchange model of virtual enterprise is presented. In the model data exchange makes intersecting compromise on different objects.
Methods of artificial intelligence have been widely used in the study of investment related topics, and the methods adopted include genetic algorithm and neural network, etc. However, as different to the methods taken in the past, support vector machine is adopted in this article to perform investment strategy study for domestic stock market; investment strategy can be divided into three strategies...
With the aim to share and reuse conceptual design process knowledge, the paper proposed to apply one knowledge discovery approach-DFSSM in product conceptual design. According to the feature of conceptual design, one new approach of product conceptual design based on DFSSM was implemented, in which the DFSSM could mine design process knowledge from complex type data of conceptual design and the knowledge...
With the progress of water supply company reform, the enterprise's leaders eager to optimize the productivity by strengthening the information management in order to improve the competition ability, there is a problem of the difference between supply and sale in lots of water supply company. For this reason, this paper proposes a method: first building a data warehouse based on GIS, and next, making...
Kalman filter is introduced into the neuro-fuzzy deducing system (NFDS) operation to attenuate disturbances in measurement data. Both of Lidar and infrared radar data sets will be engaged into data fusion, because there will exist defective data points within both of which owing to the respectively distinct running mechanism. Data confidence estimator of NFDS derived from contextual information (CI)...
Along with the development of internet, a lot of new data appears in the web every day. To construct a retrieval model to adapt the new data quickly and to retrieval the new documents accurately is becoming an important research topic. In this paper, we put forward a new retrieval model by incorporating the theory of transfer learning with Markov Network. Firstly, compare term spaces network of old...
