Law enforcement monitoring plays a significant role in preventing and forbidding illegal land use behavior, and provide an efficient method for promoting orderly use of land resources and arable land conservation. In order to optimize the efficiency of law enforcement monitoring, spatial analyzing techniques are adopted to calculate the dynamic change extent of land cover, comprehensive land use degree...
In this paper, a novel multimodal hidden Markov model (HMM)-based approach is proposed for tool wear monitoring (TWM). The proposed approach improves the performance of a pre-existing HMM-based approach named physically segmented HMM with continuous output (PSHMCO) by using multiple PSHMCOs in parallel. In this multimodal approach, each PSHMCO captures and emphasizes on a different tool wear regiment...
In this paper, we describe a framework for GPS/INS based Portable Positioning System. The framework includes two main components: receiving terminal and monitoring center. In the receiving terminal, the digital compass and the GPS modules are both connected with an I/O interface in a FPGA to provide an integrated positioning solution. This integrated positioning algorithm can solve the problems arising...
As an increasing number of intellectual property (IP) infringements have been done through internet, to strengthen the IP enforcement rules in the digital environment is increasingly becoming a national consensus. The Anti-Counterfeiting Trade Agreement (ACTA), in keeping with this trend, launched a strong set of rules, but caused considerable controversy due to its specific measures that may infringe...
The urban subway emergencies of the world took place frequently which would cause great casualties and property loss, as well as unfavorable political influence on public security and stability, so far as to cause the social panic. The paper explains the concepts of public emergency and the mutations mechanism and features of urban subway emergency. It undertakes an evaluation by means of Analytic...
The widespread networks in campus provide students with rich resources, but they also provide unhealthy information which may have negative effects on students. Filtering systems have been developed to prevent web users from unhealthy web contents. However, the false positive and false negative rates of those tools are still high and thus need to be improved. In this paper, we propose an Internet...
Real-time monitoring for multiple targets is crucial in portable positioning system. In order to improve runtime efficiency of the system, we respectively use native table file and memory table in MapX to add and modify the map objects. By calculating their response time, a comparison is made to find the difference in runtime efficiency of the system. The experimental results show that the use of...
