With the development of growing number of China's mobile phone users and mobile Internet, intelligent transportation has become an effective way to solve the traffic problems. Many studies based on GPS data analysis are available. However, high costs lead to insufficient number of samples, the small number of studies based on call detail record (CDR) data analysis only apply a small range of short...
Book logistics has developed rapidly under the E-commerce environment. This design attempts to use ASP.NET (C #) in the structure of an online bookstore to make customers buy books easily through the Internet. This paper describes the design and implement of an on-line bookstore system with data mining function, and the main pages of it, database, application design and implementation are also introduced...
The lack of homogeneity in description elements and description method leads to video information sharing and management in the relative video application and management system for more management departments at all levels hampered. Based on the relevant metadata standards and the metadata technique, we put forward the railway video metadata specification, which consisted of mandatory elements, optional...
The prediction of the traffic flow can give the people important traveling information. In this paper, the traffic flow prediction problem is studied. An ARIMA model is proposed for the traffic flow prediction. The ARIMA model is trained according to the different period traffic data. Based on the different period data training, the ARIMA model is refined more accuracy. The experiments show that the...
The prediction of the traffic state can give the people the important traveling information. In this paper, the traffic state prediction problem is studied. A maximum entropy(ME) approach is proposed for the traffic state prediction, which consider the prediction process as a classification problem instead of predicting the traffic flow parameters. The traffic state is defined as six classes according...
As the basic prosodic unit, the prosodic word play an important role for the naturalness and the intelligibility for the Chinese TTS system. Although many research work have been on this research direction, the precision of the prosodic word prediction is still not satisfying. In this paper, Conditional random fields is introduced to model the prosodic predicting process. In this model, more efficient...
The multi-stage influence diagram theory and the game theory are introduced to maneuvering decisions in the multi-fighter cooperative air combat. A multi-stage influence diagram game model for n-stages decision is presented, and the decision is sequential and maneuvering. Firstly, principles that the multi-fighter cooperative air combat is divided into the air combat of several small teams are determined,...
Facing to the uncertainty problem of dynamic transport network for the big cities, this paper begins from the viewpoint of connectivity reliability, analyses evaluation method for connectivity reliability, and put forward LOS-based connectivity reliability evaluation model (LOS-CRE model), that integrates traffic level-of-service into reliability evaluation, and that is reference to grades of level...
To achieve a good balance between matching accuracy and computation efficiency is a key challenge for query-by-humming (QBH) system. In this paper, we propose an approach of n-gram based fast match. Our n-gram method uses a robust statistical note transcription as well as error compensation method based on the analysis of frequent transcription errors. The effectiveness of our approach has been evaluated...
An improved Fish-Search algorithm was proposed for airplane route planning of a class of Plane-Missile cooperation. The mathematical description of this class of cooperation was introduced. Comprehensively considered such key factors of the cooperation as inter-visibility, threat, maximum distance and relative orientation, the constraint conditions and evaluation index were constructed. According...
The railway transportation safety system is a complex dynamic system with spatio-temporal characteristics. Taking railway line section as the research object, we propose a new cellular automation (CA) model - a safety system model for railway (SSM-R) - to simulate the railway safety. In the proposed CA model, we consider a railway line section as a cell and the neighbouring sections as the neighbors,...
