A proper use of these latter is fundamental in order to achieve high performance during their whole lifetime. For this reason, we consider a degradation model for the ESSs in the optimization problem. In this way, it is possible to optimize network management by taking into account ageing effects of the ESSs and maximize their lifetime. In order to deal with network uncertainties, we solve a stochastic optimization problem using a scenario approach which allows to provide a-priori level of constraint satisfaction. The effectiveness of the proposed control strategy is tested by performing simulations on IEEE 14 bus.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125529914","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 main scope is to embed different visual servoing systems (VSSs) with a processing/reprocessing mechatronics line (P/RML) in order to control different complex autonomous systems (CASs) while servicing the line in the operation of recovery of the pieces that did not pass the quality test. For achieving this objective, two different visual servoing systems are designed, tested and implemented for controlling different wheeled mobile robots (WMRs) equipped with robotic manipulators (RMs). To the first one, called eye in hand, the camcorder is located on the last link of the manipulator, thus the visual servoing system is mobile. To the second one, called eye to hand, the camcorder has a fixed position, usually positioned on a P/RML workstation. This paper is focused on video processing and control of different WMRs equipped with RM while serving the P/RML based on fixed or mobile VSSs.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116716825","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}

Most CBIR systems are designed to help physicians in the diagnostic of the pathologies. Image retrieval according to the content of the texture features can be performed through various methods developed so far. Local texture features are very beneficial for the analysis of the texture, thus, they are extensively used in image retrieval. The original LBP is improved in this paper with a new addition for CBIR called uniform extended local ternary pattern (UELTP). The method decomposes the image into objects; local texture features are extracted and stored into n-dimensional texture feature vectors. Then, the images are frequently obtained from a huge database dedicated for images using these vectors. In this paper, the performance of LBP descriptor, LTP and ELTP are evaluated for CBIR. According to the results, uniform extended local ternary pattern more accurate than other descriptors in terms of image retrieval.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123510050","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 existing control input that has two decoupled control efforts with one handling the tracking and the other dedicated for formation is now further augmented with a repulsion term that resolves collision with other team members and obstacles nearby. Assuming that each UAV takes the same and constant velocity. This newly-added control component adjusts the UAV’s heading angle to the opposite direction in relation to the UAV’s closet neighbors and obstacles where collision may occur. This repulsion term can also be expressed as a function of relative bearing angles alone, making it possible to be estimated/measured by onboard vision sensors in the presence of communication loss. Regarding communication topologies, an all-to-all communication, a ring topology, and a cyclic pursuit topology are studied. The effectiveness of the proposed collision/obstacle avoidance scheme is demonstrated by numerical simulation examples.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"35 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126239489","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}

Nowadays, it is used mostly within Eastern Christian churches. Few computer software applications deal with Byzantine music and the imperfect command of Byzantine music theory among singers often requires parallel classical notation staves. A software application written in C++ has been written, which enables the user to write simple musical scores using standard notation, as well as Byzantine music compositions using a subset of the specific Byzantine notation. The application can be used to produce transcriptions of Byzantine-notation compositions into their classical notation counterparts. Extensive data structures and algorithms for containing and manipulating the data, as well as interacting with the computer user, have been developed. Additionally, the application offers some serialization capabilities, as well as preliminary support for pitch tracking. By offering the functionality described above, the application is an example of modern technology being used to preserve cultural heritage.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131377898","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 hierachical Plant wide operation in wastewater treatment plants: overall efficiency index control and event-based reference management 污水处理厂的分级全厂运行:整体效率指标控制和基于事件的参考管理

An integral performance index (N/E index) is defined to measure the removal efficiency as the ratio between the nitrogen eliminated in the biological rectors (KgrN) and the energy (KWh) required to remove that amount of nitro genated compounds. That index is controlled by an upper level PI controller that changes the dissolved oxygen (DO) set point of the lower level PI control loop. When the DO concentration is driven to excessively low limits, the N/E index set point can be unreachable. Under this situation, the nitrogen elimination can be negatively affected. Therefore, it is not desirable to keep the plant in this situation for a long time. Therefore, an event-based controller is implemented to adapt the N/E index set-point to realistic values preventing long operation periods with the lowest DO concentration.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132232043","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}

These are applied commonly to evaluation of variables and/or parameters of chemical systems, which cannot be measured by technical means. Practical software sensors are often grounded in the extended Kalman filtering (EKF) method applied to estimation of this and that stochastic model. Usually, a conventional chemical system consists of an It-type stochastic differential equation representing the chemical reaction's dynamics and a discrete-time equation linking the model's state to the measurement information. The focus of this research is on the numerical stability of various EKF-based software sensors in the presence of round-off errors. Our case study exploration is fulfilled on the famous Van der Vusse reaction model but used with an ill-conditioned measurement function, here. We reveal that only square-root versions of the EKF-based software sensors (grounded in numerically stable orthogonal transformations) are the methods of choice for state and/or parameter estimations of stochastic chemical systems in the presence of round-off and other disturbances.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134085351","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 identification of an unmanned quadcopter in accelerated flight using a grey-box modeling approach is investigated. The classical approach of using either first-principles modeling (white-box modeling) or pure observations modeling (black-box modeling) have limitations particularly for real-time applications. Radial basis functions neural networks (RBF-NN) were used to estimate the rotor dynamics parameters (motor PWM outputs) from an unknown flapping dynamics model. The identified models shows that a RBF-based grey-box modeling approach specifically in aggressive maneuvers, has benefits in both modeling accuracy, network size and robustness to noise.","PeriodicalId":308427,"journal":{"name":"2018 22nd International Conference on System Theory, Control and Computing (ICSTCC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133940165","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}
