COPE is a forum for editors and publishers of peer-reviewed journals to discuss all aspects of publication ethics.</span> COPE provides advice to editors and publishers on all aspects of publication ethics and, in particular, how to handle cases of research and publication misconduct. COPE does not investigate individual cases but encourages editors to ensure that cases are investigated by the appropriate authorities (usually a research institution or employer).</p> <p> <img src="" alt="" width="100" height="75" /></p> <h3>------------------------------------------------------------------------------------------------------------------------------------</h3> <h3>Indexing:</h3> <table style="height: 46px;" width="540"> <tbody> <tr> <td width="60"> <p><a href=";hl=en&amp;hl=en&amp;user=M9ezo4QAAAAJ"><img src="" alt="" width="22" height="22" /></a></p> </td> <td width="60"> <p><a style="color: #009de5;" href=""><img src="" alt="" width="22" height="20" /></a></p> </td> <td width="60"> <p><a href=""><img src="" alt="" width="22" height="20" /></a></p> </td> <td width="60"> <p><a href=""><img src="" alt="" width="70" height="42" /></a></p> </td> <td width="60"> <p><a href=";issn=26938464&amp;amp;uid=r808f4">ResearchBib</a></p> </td> <td width="60"> <p> </p> </td> <td width="60"> <p> </p> </td> <td width="60"> <p> </p> </td> <td width="60"> <p> </p> </td> <td width="60"> <p> </p> </td> </tr> </tbody> </table> <p> </p> Designing a predictive controller for an underwater robot to track certain targets using the sliding mode technique 2022-08-16T20:31:20+10:00 Abdullah L. S. <p>In this research, the goal of designing an adaptive control system is to overcome the uncertain values ​​of a robot underwater and to prove its asymptotic stability by using nonlinear control theory, in the design of the mode controller. Sliding After defining the sliding surface, the control law must be selected in such a way that it satisfies the sliding condition and results in the stability of the system. The results obtained through the theory of the problem that shows the stability of the closed loop system show the Lyapunov stability of the system. Also, the simulation results obtained at the end show the time characteristics obtained and the position errors of the work power in the improvement and development of the control methods used for underwater robots.</p> 2022-08-16T00:00:00+10:00 Copyright (c) 2022 Journal of Research in Science, Engineering and Technology Risk assessment and management based on the process analysis of risks and their feasibility in gas-pressure reduction stations 2022-08-19T00:55:25+10:00 Kabanov Oleg Vladimirovich <p>Natural Gas as a cheap, clean, easy to transport &amp; with high heating value is one of the most important sources of energies used all over the world. City Gate Stations (CGS) are one of the main and important parts of natural gas distribution systems. Considering the sensitivity of the pressure reduction stations in the gasification process, it is necessary to identify all the risks and analyze their feasibility in order to prevent potential accidents and damages, and based on that, identify the existing risks and manage them appropriately. The main goal of this research is identifying process hazards and operational difficulties in one of CGSs to develop practical pathways to prevent hazardous conditions or reducing incidents consequences. HAZOP study has done and 4 nodes have defined for the process and 47 process deviations recognized by using process parameters and guide words, 113 consequences and 97 causes have identified. Then risks have calculated and evaluated by Risk Matrix and 27 recommendations including process changes, new safeguards and protective systems have suggested.</p> 2022-08-19T00:00:00+10:00 Copyright (c) 2022 Journal of Research in Science, Engineering and Technology
