The concept of the industry 4.0 in a German multinational instrumentation and control company: a case study of a subsidiary in Brazil

The study aims to present the industry's 4.0 concepts and facilities available on the market, applied in a German instrumentation and control industry in Brazil. The study aims to present advanced manufacturing technologies that are already being applied in the company studied. As a research method, a bibliographic review is done first, followed by a qualitative, quantitative and descriptive analysis of the results of a case study. The results are intended to present the company's maturity level in relation to Industry 4.0 (I.4.0) as well as to diagnose possible new applications to increase the control and monitoring of its activities. At the end of the paper, suggestions for future studies will be available to complement the methodology proposed in this study

Mathematical Modelling on Convective Boundary Layer of Non-Newtonian Micropolar Viscoelastic Fluid

This article presents the mixed convection boundary layer flow over a circular cylinder placed in a viscoelastic micropolar fluid with surface heat flux. The goveming boundary layer equations are transformed into non-dimensional form by using appropriate dimensionless variables Then, the resulting equattons are transformed into similarity equations and solved using an implicit finite difference scheme known as the Keller box method. For validation purpose, the current results are compared to previous study. With congruent results from both study. authors are convinced that the proposed model is reliable
