Probabilistic Latent Semantic Analysis (PLSA) is a powerful statistical technique to analyze relation between co-occurrence data, and has wide usages in automated information processing tasks. However it involves non-trivial computation and is often difficult and time-consuming to train when the dataset is big. MapReduce is a computing framework designed by(More)
A 57-year-old woman with refractory vasovagal syncope and a sinus pause of 6.8 seconds during tilt-table test accepted the suggestion of atrial vagal denervation. Radiofrequency pulses were delivered on positive vagal reflex sites according to the standard of heart rate (HR) drop ≥20% after high frequency stimulation (HFS). The endpoint of inexistence of HR(More)
The autonomous parking system is an intelligent technology to park a car into a small space. More and more studies have addressed this issue. However, the planned path in these studies is not smooth enough. Based on Ackermann steering geometry, the car kinematic model is established in this paper, the collision possibility between car body and obstacles in(More)
Based on the theory of the mathematical model of induction motor, the model of induction motor vector control is proposed with the simulation toolkit of Matlab/Simulink, and the related sub-system modules are described in detail and the specific illustrations of the sub-system are also given. Take a simulation of the system, the results such as the(More)
Based on an analysis of error sources of industrial robots, we build a pose error model of industrial robots with screw theory, which overcomes the defect that the error on the y-axis could not be reflected by the classical D-H parameter method. Given the error sources which influence the end-executor's accuracy, we established a screw representation of the(More)
Molecular markers have become an invaluable tool in monitoring disease status particularly of leukemias, as bone marrow samples can be easily collected for analysis during all stages of disease development including diagnosis, treatment, and follow-up. Two genes that have been used as prognostic markers in acute leukemia are Wilms' tumor (WT1) and multidrug(More)
The use of good evaluation functions is essential when evolutionary algorithms are employed for clustering. The NK internal clustering validation measure is proposed for hard partitional clustering. The evaluation function is composed of N subfunctions, where N is the number of objects in the dataset. Each subfunction is influenced by a group of K+1(More)
This paper puts forward a model of the seamless collaboration between human and industrial robot depending on the technology of using the electroencephalogram(EEG) to control the movement of industrial robots. Wavelet packet decomposition is operated on the EEG signals for analysis. EEG signal features that industrial robot motion control needs are(More)
