To effectively realize the image feature matching for geomorphic reverse measurement and rebuilding, a new matching scheme is presented, where the SIFT method are adopted to implement initial geomorphic image matching by going through five stages: scale-space construction, scale-space extrema detection, orientation assignment, keypoint descriptor and(More)
BACKGROUND Several previous reports have revealed that idiopathic ventricular arrhythmias (VAs), including premature ventricular contractions (PVCs) and ventricular tachycardias (IVTs), can originate from endocardial mitral annulus (ENDO MA). However, these data are limited to ENDO MA VAs, and little is known about the electrocardiographic (ECG)(More)
BACKGROUND Idiopathic premature ventricular contractions (PVCs) and ventricular tachycardias (IVTs) originating from the subtricuspid septum and near the His bundle have been reported. However, little is known about the prevalence, distribution, electrocardiographic characteristics and the efficacy of radiofrequency catheter ablation (RFCA) for the(More)
Since Vietnamese opened its automotive market to the world in 1990s, Chinese automotive firms gradually started technology and industry cooperation with Vietnamese enterprises. Based on the cooperation practice, this paper explored factors of IP risk in process of technology transfer between Vietnamese-Chinese enterprises with risk theories and gave further(More)
Tele-robotics is an area of robotics concerned with the control of robots from a distance, chiefly using wireless connections like Wi-Fi, Bluetooth, the Deep Space Network, ‘tethered’ connections, or the Internet. Most tele-robotic systems are teleoperated which means that it relies on the human operator’s capabilities. Many aspects like limited perception,(More)
The image feature matching is a critical step in photography measurement and rebuilding. Based on the Characteristics of topography measurement, a new topography feature matching algorithm is presented in this paper. In the algorithm, the stereo images to be matched are partitioned, and then the region matching process is used to these partitioned image(More)
Based on GIS data, a new algorithm for generating mountain terrain of predetermined shape is presented in this paper. During geographical analysis, topographic macro-attributes are convenient to grasp the general geography characteristic in huge GIS data, and four topographic macro-attributes are designed as target parameters of predetermined mountain. With(More)
It is difficult to treat industry wastewater which contains both heavy metals and refractory organic compounds. However, the Fenton-like reaction system using heavy metal ions in wastewater to decompose organics seems a promising method, which would have a positive effect on pollution reduction and wastes re-utilization. This paper is set out to(More)
