Vision-based traffic light detection has been widely studied over the past decade. However, it is still a challenging task to build a real-time and robust classifier-based detector without a high dependency on prior knowledge. In this paper, we have a deep look at the design of features and detection mechanism in the domain of traffic light detection; propose a multi-scale and multi-phase detector...
The development of smart phone software industry has brought high demands for mobile developers. The skills of developers have a great influence on the quality of software product and the success of software projects. It is necessary to examine what soft skills are important for mobile applications development while it remains unknown. In this article, based on related mobile application development...
Online customer review is one of the most important factors that influence customer purchase decision. Various factors of perceived value in review content will cause different impact on purchase decision. In this study, the decision tree approach was used to analyze the reviews collected from Tianmao and the purchase decision results collected from the simulation experiment system; in order to understand...
New system development may not require designing all components; existing components can be used. Although the reliability of each component may be available, it is still difficult to accurately predict the system reliability in the early design stage. The system designers may not access all details of component design to consider components dependencies. This work attempts to explore the feasibility...
Recently, more and more vehicles are running on the road, which causes fuel consumption and environmental pollution problems. As a significant factor to the fuel consumption, road grade is often neglected in the vehicle energy consumption model and the decision of optimal path of the vehicle navigation system because of the difficulty of its collection and measurements. This work demonstrates the...
A new slotted split-channel medium access control (SSC-MAC) protocol is proposed for multihop wireless networks to maximize concurrent packet transmissions. By adjusting the relationship between the reservation slot (RS) on the control channel (CCH), data packet transmission slot (TS) on the data channel (DCH) and acknowledgment slot (AS) on the acknowledgment channel (ACH), the channel reservation,...
Accurate prediction of Tong guan Elevation has important realistic significance in flood control of lower Weihe River. The existing predictive models of Tong guan Elevation Changes cannot use the historical data to forecast the possible changes of the nest year. This paper proposes a modeling method, using fast neural networks and feature selection techniques, completing the prediction of Tong guan...
A comparative study has been carried out on the most recent methods for Land Surface Emissivity (LSE) estimation using Landsat TM/ETM+ data. The popularly used method, the integrating NDVI and classification is chosen and analyzed further. The result shows that the estimation model is not accurate enough for LSE is underestimated at either end of the fractional vegetation cover (Pv) range which would...
Global climate change has caused sea level rise, and one of the most extremely consequences are the increased frequency and hazards of the storm surge disasters, therefore, how to effectively assess the risk of storm surge disaster is of importance to hazard reduction and mitigation. However??the storm surge forecast models have complex parameters, which computational inefficiency. Traditional large-scale...
This paper presents a multi-target distinguishing method for Frequency modulated Continues Wave (FMCW) Ladar, which is based on velocity compensated rang-doppler decoupling method. The multi-target distinguishing method could be used to detect targets within same range and different speed, and could also be used to detect high speed targets. Simulation results prove the validity of this method, and...
On mountain highways, excessive speeding appears to be the major factor that causes fatal traffic accidents. In order to find out the most significant attributes that affects the vehicle speed so that countermeasures could be applied. Therefore, based on the actual traffic data collected from black spots in four provinces of southwestern China; this paper investigated the significant roadway attributes...
Association mining is widely used in pattern discovery. For large scale financial textual data analysis, however, association mining is relatively less applied due to low efficiency in text manipulation. This paper presents a fast finance textual mining system, based on search engine and concept graph, for large scale financial textual association mining and visualization. Through the experiments...
Sideslip angle is the most widely used attributes for measuring the vehicle side slipping. Predicting the trend of sideslip angle in advance is of great significance for sideslipping precaution. In this research, small-vehicle model was selected, took steering wheel angle, yaw rate, lateral acceleration and four wheel velocities into account, and then applied neural network to build a prediction model...
Based on the actual data collected from black spots on mountain highways, this paper investigated the influences of roadways' attributes upon vehicle speed. The significance of different factors contribute to vehicle speed were represented by the modified coefficients of roadway attributes, and a model was established based on the modified coefficients. Moreover, we took advantage of Logarithmic regression...
Aiming at solving the problem of the change in world acquisition model, a new acquisition strategy which was called the acquisition based on capacity and simulation was proposed. It will enhance the efficiency of our defense acquisition. Particularly, this paper has newly contrived a workflow management system according to the strategy. The proposed strategy was achieved by information technology...
Traffic flow is a dynamic and nonlinear giant system, there is no unified criterion for evaluating traffic condition at present. According to the characteristics of mountain highway and Hall model, this paper formalizes traffic states based on the average vehicle speed. Though applying ordered logistic regression approach to specify the factors affecting traffic flow, a high accurate prediction model...
The long time and cumbersome process of spacecraft test have hampered the development of China's space industry. In order to improve the launch success rate, shorten the test time, optimize the test process, a new type of implementing project of the test and launch flow was proposed based on the theory of system engineering. In addition, this paper introduced the idea of workflow into the area of...
