We first build the structure for the resolvable group targets using graph theory. Then, the group estimation involves two stages of the target state estimation and group state (group size, shape, etc) estimation. In the first stage, based on the given group dynamic models, we derive the target estimated state set and the number of targets by using the multi-Bernoulli filter under the assumption of independence of all targets. In the second stage, we combine the graph theory with the group targets and build the adjacency matrix of the estimated state set. We thus get the number of the subgroups, the group state, the group sizes and its structures. Finally, a linear and a non-linear examples are given to verify the proposed algorithm, respectively.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127346342","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 area is constantly evolving with the needs to solve complex problems of welding automatization and robotization, and also thanks to the continuous advances in measurement technology and robotics. Besides the use of welding robots for serial production with dedicated tightly defined trajectories, systems for automatic welding of a previously undefined path or paths, which the operator can't manually define because of its complexity, are developed. This paper covers the general description of the cognitive module and its required functions. After that, the procedure for 3D robotic welding with a laser profile scanner is described in more detail. The task of controlling the end effector of the robot during the welding process is described. Then an algorithm for 3D model construction based on data from the profile scanner is presented. Development of the cognitive module prototype with use of a 2D profile scanner led to experimental evaluation of its function in the task of automatic cavity repair, which is discussed in the last part of the paper.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"383 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123507567","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 standard formulation of the CBMeMBer filter assumes that the target birth intensity is known as a priori. In consideration of the fact that the target splitting event should be random and could happen at an arbitrary position, this assumption becomes unrealistic. In this paper we apply the adaptive birth distribution to solve the problem of tracking splitting targets. The adaptive birth method is turned out to be more suitable to the splitting target problem. The performance is evaluated by the Optimal Sub-pattern Assignment(OSPA) metric and cardinality estimate. Simulations show that the adaptive birth CBMeMBer is responsive to the changes in cardinality with small OSPA distance.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129795702","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 successful development of such techniques has diverse purposes, such as reassigning limited resources (e.g., public transportation) properly by counting floating population or categorizing the type of events based on the identification of crowd interactions. While existing counting approaches are mostly based on regression models that directly map features to the corresponding class labels, we propose a conditional marked point process (CMPP)-based approach to count individual persons even in moderately crowded scenes. We use a mixture of Bernoulli shape, which is a stochastic model, estimated from the training set with extrinsic shape distribution that determines the size of a shape for the given location in an input image to count the proper number of persons in different types of scenes. The experiment was carried out on PETS2009 which is a well-known public dataset. It was concluded from the experimental results that the proposed approach can be an alternative to the conventional MPP-based approaches.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115937433","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 this paper, a time-optimal trajectory planner is proposed, which tracks the specified B-spline path with limit jerk. This planner utilizes the master-slave strategy to plan trajectory for all axes. In the preprocessing stage, switching points are divided into two types: critical points and axis switching points. By detailed classification and S-shape velocity planning of adjacent critical points, the continuous turning problem in B-spline curves is solved. In order to reduce the global execution time under the physical constraints, an iterative optimization method is employed in the velocity profile and the bang-bang control with limit jerk is realized. The proposed algorithms are simulated on a manipulator model with three links. The result shows that the algorithms can be applied to complex B-spline path tracking and generate trajectory for each axis under jerk constraint, which reduces the vibration effectively.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123031024","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}

However, current obfuscation methods either rely on secure memory to store the key or incur large design overhead with camouflaged gates. We propose a set of don't care based obfuscation primitives and show how they can be used to make the design IP secure with little area and delay overhead. While existing logic obfuscation techniques rely on hiding layout information from circuit attackers, our approach is different in that we introduce confusion in the sub-circuit functionality in order to increase the RE complexity while meeting the overall circuit specification. We also study how to maximize the complexity of the RE attacks and incorporate the conclusion of such a study into the proposed don't care based obfuscation method. Simulation results for ISCAS-85 benchmarks confirm that we can achieve circuit obfuscation with very high RE complexity and small design overhead, more specifically, an average 7.73% delay overhead and 5.51% area overhead.","PeriodicalId":407031,"journal":{"name":"2016 International Conference on Control, Automation and Information Sciences (ICCAIS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126296909","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}
