Products are the main carrier with which the enterprises and the consumers communicate with each other, the product style contains two kind of information from the enterprises and the consumers side. Product style map is an effective tool for product strategy planning. So word processing technology was firstly investigated including methods of new words identification, words semantic measurement,...
While FastSLAM algorithm is a popular solution to SLAM problem, it suffers from two major drawbacks: one is particle set degeneracy due to lack of observation information in proposal distribution; the other is errors accumulation caused by inaccuracy linearization of the robot motion model and the observation model. To overcome the problems, we propose a new Jacobian free CFastSLAM algorithm. The...
In this paper, a low-dimensional atmosphere model with general circulation is researched. The model is the classical Lorenz-84 system combined with seasonal force. The stability and the chaotic behavior of the seasonal forcing model are studied. By means of the Lyapunov exponents, the bifurcation map, phase diagram and Poincare section, the dynamical behaviors of the system are described and various...
With the rapid development of oil and gas pipelines, the plugging technology which is used to increase security of pipe repairing has been starting. This article raises a new process to plug pipeline near launcher or receiver, based on the latest development of pipeline plugging technology. This process is used to change valve or maintain pipeline near launcher or receiver, is the deep application...
