In this article, we look to aid and simplify the ship's hull inspection task through a new robotic system using two arms manipulators. Therefore, we established the geometric and dynamic models of an underwater ship's hull inspection station components. In effect, the mentioned station has fourteen freedom degrees, which are eight rotations and six translations in both arms. Furthermore, we applied a PID controller in order to establish the dynamic simulation of the station using the SimMechanics software. This study demonstrates that such a station using two arms manipulators technology can make the ship's hull inspection process simple and more effective.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132555697","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 synthesized decentralized optimal control is the result of developing a solution for the Decentralized modied Algebraic Riccati Equation (D-ARE) of linear interconnected systems. The main contribution of this paper is to assure the global asymptotic stability of the system under study, using the smart combination between the quadratic function properties and the stability analysis approach based on Lyapunov direct method. The leverage of the proposed decentralized optimal approach is illustrated via simulation results on an interconnected system composed of a triple inverted pendulums, which have proven that the new stability conditions are satisfactory and efficient.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114444320","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}

How the neutral is grounded determines the behavior of a power system during a single-phase to ground fault. Thus, it decides the circulation or not of zero-sequence current. This can affect the fault impedance of transmission line and creates under-reaching issues in distance relay. To tackle this challenging problem, a new approach based on the management of the system grounding is proposed in this paper. A comparison study that highlights the merits and demerits of each grounding mode are given to test the impact of the grounding system on the fault current. Simulation results are performed in a test system under MATLAB environment.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123084409","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}

It is the third leading cause of death, after heart disease and cancer. Detection of dementia from neuroimaging data such as MRI through machine learning has been a subject of intense research in a recent year. Although many works of literatures have developed many approaches to characterize this disease and to classifier its stages automatically, currently there is no specific technique to confirm with certainty the diagnosis of dementia. Brain regions are important for prediction of dementia stages. Some of the researchers were focused on the segmentation of the grey matter, others are focused on the cortical thickness. This paper investigates how to characterize and to predict dementia stages from a 3D MR image Database. Data provided by OASIS BRAIN includes a cross-section of 175 subjects aged 60 to 96 years. The approach relies on many steps. It started with applying data preprocessing which includes registration and segmentation of the hippocampus with a Bayesian probabilistic approach based on the Markovian modeling. The second step is to extract some features from the hippocampus. Finally, the prediction of dementia stages is done with a supervised learning algorithm: Artificial Neural Network. The results evince that the proposed approach can be used to characterize and predict the stages of dementia with over 95% accuracy, considerably higher than that of conventional basic methods. This study confirms that to extract geometric descriptors from the hippocampus can effectively solve the dementia characterization problem.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"73 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126264875","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}

Localization of the brain sources that generate Electroencephalographs (EEG) has been a challenging problem in research, clinical and technological applications associated with the brain. The active areas in the brain are designed as equivalent current dipoles, and the moments and positions of these dipoles are the target to be estimated. We are formulating this EEG dynamic brain source localization problem as a nonlinear state-space model. Nowadays, particle filters (PF) represent the optimality in estimating the nonlinear and non-Gaussian systems. However, PF are inefficient in high-dimensional state-spaces because the number of particles desired increases super-exponentially with the dimension of the state. Unscented particle filter (UPF) has been emerged recently to improve the performance of PF. Therefore, we introduce a newly Multiple Unscented Particle Filter (MUPF) to deal with the problems that have high-dimensional spaces. In addition, we propose the MUPF algorithm to estimate the positions and the moments of the dipoles over time. Simulation results on synthetic and real EEG data using the MUPF provide effective tracking for dipole localization compared to the standard PF, multiple PF and UPF.","PeriodicalId":216138,"journal":{"name":"2019 International Conference on Advanced Systems and Emergent Technologies (IC_ASET)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115896204","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 first strategy is based on the use of one nonlinear controller in the entire operating region. The second one consists of designing only one linear and one nonlinear controllers for each linear and nonlinear models, respectively. Therefore, both backstepping and sliding mode controllers were separately implemented to swing rapidly the pendulum from its initial position into the desired angle. Then, the linear state feedback controller guarantees its stabilization. The experimental results showed that the proposed composite controller reduced the samples comparing to the classical scheme. Moreover, the backstepping ensured the rapidly convergence to the desired angle.
