Modeling Parameters of Reliability of Technological Processes of Hydrocarbon Pipeline Transportation
Purpose. Development of a methodology for optimizing the technological parameters airlift operation, based on analysis pressure balance in annulus and drill string that occurs during drilling. Methodology. The tasks were solved by complex research method, which includes review generalization literary patent sources, analytical studies existing methods drilling with reverse circulation using an ...
The experiment of the rheocasting-rolling for semi-solid magnesium was carried out on the equipment made by ourselves in our laboratory. Semi-solid AZ91D magnesium slurry was prepared by cooling slope and mchanical sirring The evolution of microstructure under different technological parameters were studied. The results show that the technological parameters have great influence on the microstr...
in this thesis, we consider a mathematical model of cancer with completely unknown parameters. we study the stability of critical points which are biologically admissible. then we consider a control on the system and introduce situations at which solutions are attracted to critical points and so the cancer disease has auto healing. the lyapunov stability method is used for estimating the un...
