To solve these problems, the theoretical model of controlling ultrasonic amplitude output is established by feedbacked current. The theory is based on Kirchhoff's circuit laws. And then a method of constant amplitude control is proposed by controlling buck converter's output voltage. By MATLAB/Simulink, the simulation shows that the current is constant though the load changed. The result proved the scheme of constant amplitude control was feasible. Finally, the PID algorithm has been completed in the ultrasonic drive system based on ARM chips. The amplitude of the transducer was measured by a laser Doppler vibrometer and compared with the constant voltage control and the constant power.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116160414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, there appeared some well-performed local stereo methods and these state-of-the art methods show comparable performance in terms of quality and better performance in terms of speed with global methods on the Middlebury datasets. However, previous surveys of stereo matching do not consider disparity refinement step, which plays a significant role in improving depth quality for local methods. Thus, in this paper, we focus on the evaluation of the existing disparity refinement approaches and provide some insights into local stereo matching.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"448 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116145699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Workload range is so wide that optimization is necessary to be considered to improve execution performance on all load conditions. Firstly, this paper details least maximum strategy to optimize each joint's torque, and in reverse can effectively improve the whole manipulator's carrying capability. Further, with the problem of relative poor performance under heavy load to trace the established trajectory, feedforward compensation structure is employed at the level of centralized control to help. Finally experiment as process simulation of space docking is conducted to verify such methods, with “Matlab & ADAMS” platform. The experiment results indicate that the optimization method can effectively improve the load capacity.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129557638","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Taking into account the internal structure of the light field data, depth map of the captured scene is extracted to calculate the surface normal. Using nonlocal matching by combining chromaticity, normal and spatial location information in an anisotropic window, the shadow confidence of each pixel is established. For effectively utilizing the prior knowledge, MRF (Markov random fields) is introduced to obtain the shadow label of each pixel iteratively. Once obtained the shadow labels of pixels, inpainting with an energy minimize framework is used to remove shadows. The experimental results on real data demonstrate good performance of this algorithm.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127255173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The developed novel grasper can imitate the catheter grasping motion of the surgeon during VIS. The grasper is a key factor to drive the catheter into the vessel accurately. It adopts a common structure like the pliers, which can guarantee that the catheter can be clamped on the same axes with other via hole. The clamping force can be adjusted by the screw through changing the entered length of the screw to change the compression length of the spring. The clamping system consists of two graspers both master side and slave side respectively. The graspers clamp the catheter just like the surgeon's hand and the clamping method of the grasper imitates the surgeon's operation. The performance evaluation experiments of the novel grasper were done. The experimental results indicated that the grasper was effective to clamp catheter tightly to increase accuracy of surgery, which can satisfy the design demand.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130700278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 3-CCD camera system is often used for tiny target measurement in ICF target positioning. Most of the current pose measurement methods utilize the well-known digital image processing technology to extract the target features in each image, then calculates the target's spatial coordinate and rotation matrix by integrating the feature values from three CCDs. Therefore, feature extraction errors in each image are superimposed in final result, which reduces the pose measurement precision. In this paper, we propose a solid model-based method which matching the target as a whole by the grey values in each image without utilizing image processing technology. The solid model matching optimistic problem is solved by genetic algorithm (GA).

Such kind of data makes the event processing for network security significantly difficult. Current cluster algorithms use cluster center to calculate the distance which leads to fairly big calculation errors. In order to aggregate the massive alert data effectively and identify important security events accurately, we propose an improved Iterative Self-Organizing Data Analysis Techniques Algorithm based on Similarity Radius (SR-ISODATA). In the presented algorithm, optimal sequence comparison method is used to calculate the attribute weight of alert data, and different similarity calculation methods are chosen due to different properties of alert data; the merging and splitting criteria are revised, the clustering center in the original ISODATA algorithm is replaced by the average similarity radius and the distance calculation in the original algorithm is replaced by the similarity. Extensive experiments using the alert experimental data on KDDCUP99 show that the SR-ISODATA algorithm gets a high alert compression rate and a higher purity of each cluster.","PeriodicalId":427762,"journal":{"name":"2014 IEEE International Conference on Information and Automation (ICIA)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130971233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
