Technology Reports of Kansai University (ISSN: 04532198) is a monthly peer-reviewed and open-access international Journal. It was first built in 1959 and officially in 1975 till now by kansai university, japan. The journal covers all sort of engineering topic, mathematics and physics. Technology Reports of Kansai University (TRKU) was closed access journal until 2017. After that TRKU became open access journal. TRKU is a scopus indexed journal and directly run by faculty of engineering, kansai university.

Hydrodynamic journal bearing is one of the simplest types of bearings which faces a problem of high temperature generated with the developed industrial applications. The main goal of the present work is to carry out CFD analysis to study a thin film journal bearing supporting rotating shaft of an electric motor used to drive a cement ball mill considering thermal effect and elastic deformation. Fluid structure interaction FSI technique was used to discuss the effect of different working parameters such as journal speed and clearance ratios on the pressure distribution, temperature distribution, total deformation and the state of stresses induced in bearing. A bearing with its real dimensions has been analysed in the present wok while most previous works done for bearings with hypothetical dimensions. For this purpose, thermoelastohydro dynamic analysis for such bearing was mathematically modelled using CFD technique based on three dimensional Navier Stokes, continuity, and energy equations in fluid film and solid materials. Oil viscosity was considered as a function of pressure and temperature. The governing equations with suitable boundary conditions have been solved using ANSYS FLUENT 19. The results showed that the present CFD model was well validated with that of Amit Chauhan (2014) and the oil film temperature increases by 1% to5% while the maximum oil film pressure decreases by 30% to 50% when the journal speed increases from 490 to 1500 rpm. The bearing liner total deformation decrease by 25.3% to 47.3% when the bearing works at the same range of journal speed
Provision of appropriate learning strategies will be able to improve concepts understanding and applications of graphic design concepts. This study aimed to determine the effect of Collaborative e-learning support strategies for a classroom and self-regulated learning (SRL) outcomes and concepts application. Data analysis was performed with the MANOVA statistical test. The results of the study concluded: (1) There is a significant difference in the learning outcomes of concepts understanding between students who implemented the Collaborative e-learning (CeL) strategy and students who implemented the Collaborative Non e-learning (CNeL) strategy (p = 0.000). (2) There is a significant difference in the learning outcomes of the concepts application between students who apply CeL strategies and students who apply CNeL strategies (p = 0.000). (3) There is a significant difference in the learning outcomes of concepts understanding between students who have high and low SRL (p = 0.049). (4) There is a significant difference in the learning outcomes of concepts application between students who have high and low SRL (p = 0,000). (5) There is an interaction between the CeL strategy and the CNeL strategy with high and low SRL towards the concepts understanding learning outcomes (p = 0.002). (6) There is no interaction between the CeL strategy and the CNeL strategy with high and low SRL to the learning outcomes of the concepts application (p = 0.761). The use of CeL strategies can improve SRL of understanding graphic design concepts and application. In building the ability to understand and apply graphic design concepts in the Mathematics Education Study Program, the application of CeL strategies in this study is better than CNeL strategies in terms of improving the application ability of students' mathematics learning concepts
