Trajectory planning of robots is not only an important research field of robotics, but also an challenging combination of artificial intelligence and robotics. Trajectory planning is a key technology of Unmanned Aerial Vehicle (UAV). It is also a prerequisite for autonomous navigation of UAV. Under the static environment distributing of obstacles, seeking a shortest path from the starting point to...
In order to solve the parallel algorithm for Petri net system with concurrent function, to realize the parallel control and execution of Petri net, two different functional partition strategies based on P- invariant and T- graph are proposed for the parallel algorithm of Petri net system. Firstly, after the analysis of Petri net model and concurrent function, the basic idea of P/T network system function...
In order to solve the parallel algorithm for Petri nets system with concurrent function, to realize the parallel control and execution of the Petri nets, the Petri nets parallel subnets conditions were proposed, that provides the theory basis for judging P- invariant whether was the parallel subnet. Firstly, we according to the concurrent character of Petri net model, to analyze the parallelism of...
The progress of internet and communication technology has called for changes in College English teaching mode. The traditional teacher centered method can't keep up with the society. The 21st century needs people who are autonomous learners. Consequently, teachers have the responsibility to implement internet and communication technology into their teaching and involve developing student's learning...
This paper proposed a new algorithm using invertible matrix transformation XCJRCT to eliminate the spectral redundancy, as well as combining with lifting scheme discrete wavelet transform (DWT) and set partitioning in hierarchical trees (SPIHT) coding. The experiment results show that the capabilities of lossless image compression are far better than JPEG-LS, WinZip, ARJ, and DPCM. With Canal test...
Due to the features of unconventional emergency itself, “Scenario-Response” is regarded as a more effective emergency management mode to unconventional emergency. The whole process of disposal assessment is an important basis for relief decision. This paper describes the scenario-based assessment of whole unconventional emergencies disposal process (pre-disposal, the medium-term disposal, post-disposal),...
Disaster assessment of the whole process of unconventional emergency is an important basis for relief. Unconventional emergency is dynamic and evolutionary which is concentrically embodied by difference information features and assessment objectives of each stage. Based on above, suitable assessment methods should be used. This paper studies on unconventional emergency information features and disaster...
The purpose of this paper is to analyze individual customers' preferences for service channels of Chinese commercial banks in order to shed light on how these banks are able to effectively target their potential customers. A questionnaire survey was administered to the urban residents in two Chinese vastly different regions. Contingency analysis and optimal scaling were adopted in the analysis. The...
