    A mathematical model and animation of the dynamic system of the passive spring damper of oscillations was built. The effect of the spring dynamic absorber was calculated using the proposed method with two-sided estimation of the local error. These calculation formulas make it possible to obtain an approximation to the exact solution from above and below, as well as to calculate the value of the main term of the local error

    The shaping of a fused surface to the influence of centrifugal rotational motion

    Get PDF
    Different methods of surfacing are using to strengthen machine parts. The surfacing will perform with using simultaneous centrifugal rotation compared to the traditional surfacing scheme. The disk is located in a fixed position during the entire surfacing process according to the traditional scheme. The rotational movement is carrying out with a certain angular velocity at the time of fusion of the metal laye

    Thermal connection of cylindrical shells

    The main ratios for determining the distribution of displacements, as well as the temperature field, bending moments and forces on different sections of the elastic cylindrical shell during the connection process, were obtained. The law of distribution of the intensity of heat sources has been determined, which provides for a given time a temperature field that differs as little as possible from the given one. The stress-strain state of the heating stage was studied for different sets of boundary conditions

    Framework for knowledge asset management in community projects in higher education institutions

    Innovation in education encourages stakeholders to explore and apply different ways of looking at problems and solving them. Large-scale community projects (LSCPs) in a higher education institution (HEI), provide an ideal environment for combining curriculum outcomes, education innovation, real-world engagement and knowledge assets. However, current research that focuses on knowledge asset management in innovative learning is limited, and this study aims to contribute a holistic approach for managing knowledge assets in this context. In this study, we designed a knowledge asset management framework for LSCPs in higher education taking cognisance of innovative educational model characteristics. We applied the framework by mapping it to a community project module from an HEI using the elements of the framework as a guide. By using the knowledge asset management framework for LSCPs in higher education, an HEI can ensure that their community module enables strong support to the community, that students’ knowledge and skills are enhanced and that all new knowledge assets created during the project delivery, are captured and stored using innovative technology sets.http://link.springer.combookseries/558hj2020Informatic
