Methane is a hazardous gas, which, thanks to its density, tends to gather under the ceilings of mine shafts or rooms where it is present. When mixed with air, it is explosive within the 5 - 15 % range and that is the reason for the highly hazardous nature of the given gas despite the fact that under normal conditions, it is not dangerous for people. The objective of the present paper is to examine, using numerical gas glow modelling a potential building protection design for buildings located in areas with terminated mining activity and thus exposed to the risk of methane ingress and, as the case may be, causing in estimable losses of property or even human lives. The exclusiveness of our approach involves the effort at visualising and showing how the gas will behave in a porous environment in the model situations we put to the test. Unless numerical flow technology, generally referred to as CFD (Computational Fluid Dynamics) software, is used, the situation in the underground may practically never be identified and it is specifically thanks to the use of the Fluent software that we can theoretically model and subsequently realise how the surrounding conditions may change and affect flow from the underground to the surface and change the immediate conditions there. The Gambit software tool was used when creating the geometrical model of the working area; the CFD Fluent software by ANSYS, Inc. was used to model gas flow.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131646719","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 the production is connected to natural raw materials deposits, where the process environment models and activities cannot be fully determined, the human supervision will be still necessary. Classical process control, with the external system description of the dynamic behavior, uses the transformation of input actions to output reactions for the model design. Similarly for the process visualization the classical methods - SCADA (Supervisory Control and Data Acquisition) systems are used. Modern control theory is based on state representation of systems, caused by the necessity to obtain more information to understand and describe the dynamics of complex system in the control process. Resulting state space model represents the dynamic properties of the system. The behavior of system in the state space is then represented by the state trajectory - given by the values of state variables in the observed time period. The problem is that the state variables, in many cases, do not have the physical dimension and do not describe surrounding environment. The Virtual Reality tools provide the possibility for visualization of such a virtual and complex systems description in special artificial space.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115504044","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}

Thermal resistance is determined by heat transfer area and coefficient of heat transfer. In case of convection heat transfer are considered heat transfer more often between liquids or liquid and grain material what is specific for area of raw materials processing. The values of convection heat transfer coefficient are normally gained from the experimental measurement. The contribution deal with software support for calculation of convection heat transfer coefficient, dimensionless criteria and elementary thermo-physical properties of gas media from area processing of raw materials with known composition and temperature. Functions were created in MATLAB. In article coefficient of convection heat transfer for every type of convection are expressed by dimensionless criteria where elementary thermophysical properties are proposed. According to the expressed relations was proposed general form of relation for coefficient of convection heat transfer calculation. Dependencies of convection heat transfer coefficient on different factors are showed.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124092508","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 the normal operation conditions of AUV, conventional UKF gives sufficiently good estimation results. However, if the measurements are not reliable because of any kind of malfunction in the estimation system, UKF gives inaccurate results and diverges by time. This study, introduces Robust Unscented Kalman Filter (RUKF) algorithms with the filter gain correction for the case of measurement malfunctions. By the use of defined variables named as measurement noise scale factor, the faulty measurements are taken into the consideration with a small weight and the estimations are corrected without affecting the characteristic of the accurate ones. In the presented RUKF's, the filter gain correction is performed only in the case of malfunctions in the measurement system and in all other cases procedure is run optimally with regular UKF. Checkout is satisfied via a kind of statistical information. In order to achieve that, the fault detection procedure is introduced. Two different RUKF algorithms, one with single scale factor and one with multiple scale factors, are proposed and applied for the motion dynamics parameters estimation process of an AUV. The results of these algorithms are compared for different types of measurement faults in different estimation scenarios and recommendations about their applications are given.","PeriodicalId":334936,"journal":{"name":"Proceedings of the 13th International Carpathian Control Conference (ICCC)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116503900","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}
