A system of automatic recognition hail cloud is built base on the reflectivity image in this paper. The system deals the inputting image with the cut-down, filter, dilation and erosion process, and then the cloud is extracted from the image. A new concept called reflectivity density, which is used to distinguish hail cloud from rainstorm cloud, is defined. When recognized hailstone cloud the system will find the hailstone landing position by using Hough transform to detect hook echo or detecting the pixel with a reflectivity over 60 dBZ.

The Gordian Knot of the issue is image processing with much time spending in the welding course. First, according to the principle of paraboloid of revolution reflecting, this paper puts forward laying a paraboloidal mirror in specifically position above the tip of welding wire. A part of arc light is changed into parallel one by the mirror. The reflected light shines on the area where the CCD camera can see. So the visual seam is seen long and the arc light jamming is weakened in the CCD camera. Secondly, it will be discussed that the luminous flux of the area is assured. Then the Roberts algorithm for the processing image will be discussed in the aspect of the positiveness and negativeness of the gradient element, a rule that judged seam was brought forward. The rule increases the speed of seam tracking. A welding robot system with single camera fixed on the weld torch end-effector has been established for the robot to identify the welded seam by the reflected light. The simulation and results of real application have proved the validity of the method","PeriodicalId":116729,"journal":{"name":"Sixth International Conference on Intelligent Systems Design and Applications","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127576410","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}

In order to identify, and manage of P2P traffic, some port, payload and connection features based methods were proposed. But most of them focus on identifying P2P traffic based on rules and most of them can't identify P2P traffic with new features. None of the proposed methods can effectively help controlling and managing the P2P hosts. In this paper, we created a new P2P feature set, which include most of the proposed and new P2P features proposed by us. And a new anormaly detection method based on the feature set and flexible neural tree (FNT) is applied to detect P2P hosts. This approach is the first intelligent P2P hosts detection method.

With a traditional PID controller, it will cause large overshoot or poor stability. In this paper, a fuzzy-PID controller is proposed in order to improve the performance of the servo system. The proposed controller incorporates the advantages of PID control which can eliminate the steady-state error, and the advantages of fuzzy logic such as simple design, no need of an accurate mathematical model and some adaptability to nonlinearity and time-variation. The fuzzy-PID controller accepts the error (e) and error change(ec) as inputs ,while the parameters kp, ki, kd as outputs. Control rules of the controller are established based on experience so that self-regulation of the values of PID parameters is achieved. A simulation model of position servo system is constructed in Matlab/Simulink module based on a high-speed milling machine researched in our institute. By comparing the traditional PID controller and the fuzzy-PID controller, the simulation results show that the system has stronger robustness and disturbance rejection capability with the latter controller which can meet the performance requirements of the CNC position servo system better","PeriodicalId":116729,"journal":{"name":"Sixth International Conference on Intelligent Systems Design and Applications","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133198881","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}
