Feature extraction in condition monitoring requires domain knowledge about a system and its possible fault cases. To find the most sensitive features for fault patterns, one has to evaluate the relevancy of features. In this paper the authors use ReliefF, which is a K-nearest neighbors-based feature selection algorithm, to evaluate the features extracted from an induction motor dataset. The dataset contains data from eight different health states of an induction motor. Feature relevancy is calculated for each health state. The selected features are fed into a simple Bayesian binary classifier to calculate the most likely health state. The method provides insight into the relevance of features by sensor type and also by signal processing type. The evaluation of similarity among the selected features can help identify similar faults. The results obtained emphasize the importance of domain knowledge in the proper design of features. Furthermore, by considering experimental data obtained for multiple loading and noise conditions, the feature selection method indicates features which are best suited for diagnosing specific faults, regardless of external conditions. Such information can support the creation of robust monitoring systems.","PeriodicalId":201658,"journal":{"name":"2018 23rd International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117143025","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}

Recently, advances have been made to replace the arduous manual trial-and-error design process with optimization methods based on dynamic simulations. In these approaches, the gripper fingers are parametrized and evaluated by simulating multiple grasp sets in order to obtain the quality score, which is subsequently optimized. The computational efficiency of this process depends on: (1) the choice of the scoring function that provides robust evaluation with minimal number of grasps, (2) the choice of optimization algorithm that converges to global optimum quickly and (3) the choice of optimization method and meta-parameters. In this paper, we present considerations pertaining to these three problems. We use the previously proposed gripper finger design and optimization methods for generating a finger cut-out for an asymmetrical object used in industrial assembly tasks. We suggest two new alignment quality scores and compare their efficiency with preexisting methods. In addition, compare the performance of two optimization methods (one local and one global) and find the meta-parameters for the local method.","PeriodicalId":201658,"journal":{"name":"2018 23rd International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126515266","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 purpose of the system is to make optimal use of available resources to cover the electricity needs of the whole microgrid. Thanks to the energy exchange system, in addition to exchanges with the distribution network, the system also allows trades within the microgrid, between its participants. This way, users can get better offers for buying and selling energy than from the grid. The developed system uses linear optimization tasks to determine optimal power flows between microgrid's nodes. In order to do that, the system uses forecasted power generation profiles and consumer demand profiles, which come from prediction modules. Full decentralization of the system allowed for practically unlimited scalability compared to centralized systems. Decentralization also means better reliability and gives users the opportunity to make any changes to the optimizer. The system has been implemented in Python using free tools and libraries so that it can be implemented on any computer with an interpreter of that language.","PeriodicalId":201658,"journal":{"name":"2018 23rd International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"296 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123184969","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 base model used for numerical simulation is introduced. Under certain assumptions concerning steady state analysis, the differential equations describing the process are solved analytically for two cases: zero and nonzero inclination angle $alpha$. These equations describe a constant flow rate and a corresponding distribution of the pressure along the considered pipeline for both cases. The pipe length at which the pipeline is choking (the mass flow is equal zero) for given boundary pressures and inclination angle, is also derived. Convergence of the proposed solution for inclination angle $alpharightarrow 0$ to the zero tilt solution, is proved. An exemplary practical relationship based on obtained equations is provided as a 3D chart. A test pipeline with adjustable inclination angles of its selected parts is considered. The analytic solution for the effective angle is compared with numerical solutions, which show relevant discrepancies between the results obtained for nonzero angles. Clearly, the numerical solution for a straight pipeline (with the increasing number of segments) is convergent to the analytic solution. Moreover, up to 16°, the analytic approximation (using an effective inclination angle) is sufficient, and produces similar results as the numerical simulation.","PeriodicalId":201658,"journal":{"name":"2018 23rd International Conference on Methods & Models in Automation & Robotics (MMAR)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116091260","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}
