Deformable linear objects such as cables and strings are widely used in our daily life, some industries, and medical operations. Modeling, control, and manipulation of deformable linear objects are keys to many applications. We have formulated the static deformation of a linear object using the differential geometry coordinates. In this paper, we apply differential geometry coordinates to the dynamic modeling of linear objects. First, we formulate dynamic 2D deformation of an inextensible linear object based on a differential geometry coordinate system. Second, we consider dynamic deformation of the linear object when forces/moments and geometrical constraints are imposed on the object. Third, we model contact of a linear object with a circular obstacle. It can be applied to self-contact of the linear object. Finally, we show simulation results using the proposed modeling technique","PeriodicalId":415827,"journal":{"name":"2006 9th International Conference on Control, Automation, Robotics and Vision","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131421855","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 elements of the dynamical matrix A(middot) of a given time-varying system are modelled as unknown time functions taking values inside known compact sets. The elements of A(middot) are varying inside a fixed set for a sufficiently long time interval, and, at some unknown time instants, they suddenly switch from the actual set to another one. The measure and the control matrices of the system are assumed to be known and time-invariant.

This paper presents results that illustrate a biologically inspired vergence control of a pair of 2 DOF pan-tilt cameras. This work illustrates the ability of the cortical model to perform binocular vergence with baseline independence and absence of object registration. It was inspired by a collection of discoveries in the area of neuroscience. See Schwartz (1977) [1], Tootell et al (1982) [2] and Nobel Prize Winner Hubel et al (1974) [4]. We briefly explain how the log- polar image incident on the VC can be used successfully to determine the pan angle (saccade) to perform binocular vergence on points of in the scene. A discussion at the end of the paper highlights the significant differences between this system and the conventional object correspondence systems that require matching of specific object shapes. In this model, the cortically magnified VC image is used to match the entire image.","PeriodicalId":415827,"journal":{"name":"2006 9th International Conference on Control, Automation, Robotics and Vision","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124340156","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 investigates the fully-tuned radial basis function (RBF) and compares it with the traditional fuzzy c-mean (FCM) clustering algorithm in MR image segmentation. It turns out that FCM is not only biased by the number of voxels in different groups, but also by the intensity differences between different tissue groups, while the fully-tuned RBF captures the multi-Gaussian distribution of the image intensities very well and thus it can be used to segment image intensities accurately. Moreover, in order to generate spatially smooth segmentation results, a Markov random field model is applied to the segmentation results of the fully-tuned RBF algorithm. Experimental results show that fully-tuned RBF method can capture the tissue intensity distribution more accurately than the FCM algorithm","PeriodicalId":415827,"journal":{"name":"2006 9th International Conference on Control, Automation, Robotics and Vision","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114956917","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 the literature, few researches have been done in this area. However, designing a U-FPL scheme, many designers decrease the cycle time of a U-FPL to increase its productivity and overlook the efficiency of a U-FPL. Thus it causes the increasing of equipment costs. This paper describes a model of the U-FPL that can present most U-FPLs and deduces an equation to calculate the efficiency of a U-FPL.

At this moment, congestion are solved by the involvement of two controlling mechanism, they are flow control in the TCP source and active queue management (AQM) in the link. AQM will provide feedback to the source a kind of indication for the occurrence of the congestion in the link, whereas the source will adapt the sending rate appropriate with the feedback. The indication of the feedback congestion is influenced by the number of the sources, time delay, and its sending rate. Consequently, adaptation of the sending rate based on the feedback indirectly observes behavior of other sources. This control system structure is much known with distributed control system, because the control mechanism is distributed in each source. On this structure, the source mechanism is more important than the link. This paper will explain a new algorithm, which focus more on the link as an allocation capacity controller.
