The flap control system consists of the three multi-domains; 1) electrical domain giving angle reference and performing flap control; 2) hydraulic domain supplying flow and generating torque; 3) mechanical domain transmitting the torque to the flap and driving it. Explaining these three domains, we present the full model using AMESim which is one of the most widely-used physical modeling tool. The performance analysis model of this study is constructed not to reflect detailed models of parts, but to examine main requirements from a system point of view. Thus, we could predict the main system performance of the flap control system of an actual aircraft and will develop the model in the future to utilize the detail design of parts. Lastly, Simulation results are also presented to explain the model.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126532648","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}

After surveys on different OD detection techniques, a set of image and geometric processing techniques is selected and implemented. Several public fundus images with different ophthalmologic diseases are used to experiment and to verify the performance of the proposed algorithm. The proposed algorithm tends to locate clipping circles properly by enclosing OD regions with fundus images of healthy patients. However, the algorithm is not good enough to process fundus images of different ophthalmologic conditions. The overall performance of the proposed algorithm is discussed along with several experimental results. Several future research issues are also addressed.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"294 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114088054","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}

As this complexity grows, the increment of network bus load is one of the problems. To solve this issue, using a gateway is one solution. However, if one behavior in the gateway goes wrong, sending accurate information to the gateway or Electronic Control Unit (ECU) of another domain is impossible, and this will bring malfunctions to the automotive system. Currently there are no definite evaluation entries for gateway behavior, or evaluation standards for the stability and reliability of a network using the gateway. The purpose of this paper is to propose entries for validating CAN-CAN gateway behavior, and a validation method. Also, this paper validates the entries and the method by using an embedded system gateway.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"290 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114203184","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 contributes a new robust focus measure for 3-D shape recovery based on discrete wavelet transform and inherent sharpness approach. This novel focus measure technique utilizes no-reference sharpness metric based on inherent sharpness approach. The no-reference sharpness metric estimates a perceptual sharpness score based on the coefficients of discrete wavelet transform. To obtain the data of high frequency elements in an image the perceptual sharpness metric utilizes diagonal coefficients and approximated sub-signal of wavelet decomposition. The efficiency of the proposed scheme is evaluated by comparing it with state of art shape from focus approaches by conducting experiments on real and synthetic image sequences. Two global statistical metrics are utilized for performance evaluation by conducting experiments on real world images and synthetic image sequences. The evaluation is estimated on the basis of monotonicity and unimodality of the focus measure curve. The experimented results are then discussed in various forms to support the proposed scheme.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"70 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122690915","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}

They provide fast development for programmers and broaden the type of users to include those with non-programming backgrounds. Script editors are often based on finite state machines or flowcharts in their graphical interface design. This paper proposes a nondeterministic flowchart-based script editor, which provides functional blocks consisting of nodes and edges, where nodes are units of processing robot motions or media data and blocks are groups of nodes and edges. Edges have directions along with arithmetic, relational, and logical operators. This editor is capable of linking with programs written in many different programming languages such as C/C++, Java, and Python. The proposed editor is verified by an example, where a mobile robot is operated by a generated script composed of Open Platform for Robot Services (OPRoS) Components and a legacy Java program.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133111921","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 Stuarts-type 6-DOF parallel manipulator is used as a master robot and a UAV is used as a slave robot. Since, the parallel manipulator has a limited task space, due to the fixed base, while the UAV has a practically unlimited workspace, direct space to space mapping is not possible between them. Therefore, a novel hybrid mapping mechanism has been proposed to integrate these two completely non-identical devices. This paper also describes the detailed dynamic modeling of the parallel manipulator and the UAV. Modeling of the parallel manipulator is derived by physics of the system while for the UAV, a method of system identification is used. The level of tracking accuracy presented in the simulation results verifies the efficacy of the system modeling, hybrid mapping, and overall control mechanism. Multilevel control architecture based on PID controllers, in local actuator joint spaces, for the master manipulator and the slave UAV is also presented in this work.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133125438","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 classical rigidity of formation is used in the field of distance-based formation control as a fundamental tool to guarantee a locally unique formation shape with given inter-agent distances. We assume that there are some angle constraints in addition to the existing distance constraints. Then the formation could result in a rigid formation shape even if it is not rigid in the viewpoint of classical rigidity. Weak rigidity distinguishes whether the formation with additional angle constraints can maintain its shape. Relation between classical rigidity and weak rigidity is addressed and used to derive some useful results.","PeriodicalId":140598,"journal":{"name":"2017 17th International Conference on Control, Automation and Systems (ICCAS)","volume":"225 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133384310","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}
