  The development of an efficient procedure for 3D modelling and finite element simulation of metal foams
  is one of the greatest challenges to engineer researchers nowadays. Creating 3D CAD model is alone a demanding
  engineering task due to its extremely complex geometry, and the proper finite element analysis process is still in the
  center of the research. The aim of this project is to analyze the related literature and to adapt the results may be
  considered.

  Nowadays the importance of renewable energy is growing, and the utilization of the low wind energy potential is getting crucial. There are turbines with low and high tip speed ratio. Turbines with low tip speed ratio such as the Savonius wind turbine can generate adequate amount of torque at low wind velocities. These types of turbines are also called drag machines. The geometry of the blade can greatly influence the efficiency of the device. With Computational Fluid Dynamics (CFD) method, several optimizations can be done before the production. In our paper the Savonius wind turbine blade geometry was based on the so-called Myring equation. The primary objective of this paper was to increase the power coefficient by modelling the effect of the wind on the turbine blade. For the sake of simplicity, a 2D cross-sectional area was investigated in the simulation with ANSYS CFX 19.1.

  The aim of our paper is to increase production efficiency of a small and medium sized enterprise by
  applying cost-effective process development tools. The existence of the firms depends on their business processes,
  because optimally-organised process is a key in the run of business (business run) in a productive way. In order to
  keep and grow the competitive edge with the competitions, firms must supervise their processes with constant
  frequency, and if it is needed, procedures must be developed. In this case, company can resort to both human and
  physical resources. Our experiment focused on the development of an assembly process at a small sized enterprise.
  Applying process modelling techniques, and diagnostic procedures, and also data gathering methods we try to get to
  define corrective actions, with which the whole lead time can be reduced by 50%. For investigate and rank waste we
  use failure mode and effects analysis and 5 whys methods.
