Flexure hinges have more advantages than conventional hinges with advantages of no friction, no backlash, high precision and high stiffness. In this paper, design and analysis of the two degrees of freedom flexure-hinges based micro-stage are performed. The lever amplified principle is used, which has a lot of superiorities for applying to the micro-stage through amplifying the displacement of the piezoelectric actuator (PZT) to obtain a lager output displacement at the stage's end-effector. The ANSYS software version 10.0 is exploited to analyze the displacement and natural frequency.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117040328","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}

This paper considered a single-machine charging job scheduling problem and proposed a fuzzy goal programming method to get an optimized cost and operational result by considering the different charging cost brought by Time-of-use price mechanism and the characteristic of batteries, which affects the charging process time, charging efficiency and charging unit power consumption. In the proposed method, a fuzzy relation model is developed to deal with the multi-objective situation to satisfy various goals, by considering the importance relation between goals. The intention of the decision maker is satisfied well. The decision maker can control the parameter to balance the emphasis on goals or on relations according to variety of manage policy.

It was invented by Given Imaging in 2000 to solve the problem that the conventional tools cannot explore the entire small bowel. As it is non-invasive, reliable, and safe, it has been widely applied around the world. Although the clinical findings of CE are promising, there still exist some limitations. The main problem is that it produces over 50,000 images during one examination. It is a highly time-consuming and labor-intensive task to inspect such long video for clinicians. Moreover, CE images are lack of prominent characteristics, which make it difficult to diagnose diseases even for an experienced clinician. So it is desirable and necessary to develop a tool to assist clinicians during diagnosis. In this paper, we propose a method to reconstruct the 3D texture surface of GI tract using single CE image. We applied Shape from Shading (SfS) technique to represent the surface of GI tract using 2D CE images. It is a novel way to view the abnormalities, especially for polyp, which can lead to a more efficient examination. Preliminary experiments on real CE images have been conducted. The results show that our method achieved promising performance.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128446334","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}

Such a novel DTCVZD model is designed based on the elimination of an indefinite complex-valued error function, instead of a square-based non-negative energy function associated with the discrete-time complex-valued gradient-based dynamics (DTCVGD). Comparing with the well-known (generalized) Newton fractals (i.e., the famous fractals generated by the well-known Newton iteration), we find that the novel Zhang fractals synthesized by the proposed DTCVZD model incorporate such Newton fractals as special cases. The Zhang fractals generated by the novel DTCVZD model are completely different from Newton fractals. The DTCVZD model using different types of activation functions can be seen as a new iterative algorithm to generate new fractals, i.e., Zhang fractals.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130045118","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}

Network-induced uncertainties including time-varying unknown network-induced delay and data packet dropout are assumed to be existing in both sensor-to-controller link and controller-to-actuator link, where the total network-induced delay is transformed into uncertainty of system model, and the data packet dropout is described as a two-state Markov chain. Then, the closed NCS with network-induced uncertainties is modeled as a Markovian jump system with model uncertainty. An observer-based fault detection filter is presented as a residual generator and a performance index is proposed to deal with the robustness issues, which is to enhance the robustness of the residual generator against network-induced uncertainties and disturbances, without significant loss of the faults sensitivity. Sufficient condition for asymptotically mean-square stable of residual dynamics is derived, and the desired RFDF is obtained, which is constructed in terms of certain linear matrix inequality.

In this paper, for the VR system, we use the master side as the controller, and we use the open source code DCMTK to read the information of “.DCM” file and carry out the CT image segmentation for the Virtual Reality based Robotic Catheter System and we use Open Scene Graph (OSG) to realize the 3D image output and catheter control of the Virtual Reality System. We present virtual reality simulators for training with force feedback in minimally invasive surgery. This application allows generating realistic physical-based model of catheter and blood vessels, and enables surgeons to touch, feel and manipulate virtual catheter inside vascular model through the same surgical operation mode used in actual MIS. The experimental results show that the error rate is in an acceptable range and the simulators can be used for surgery training.","PeriodicalId":373152,"journal":{"name":"2012 IEEE International Conference on Automation and Logistics","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133746566","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}
