• H 1 -conforming finite element cochain complexes n cartesian meshes

  F. Bonizzoni, G. Kanschat

  Test Clara Collection (2022). 2

  
  

  Abstract

  We develop tensor product finite element cochain complexes of arbitrary smoothness on Cartesian meshes of arbitrary dimension. The first step is the construction of a onedimensional Cm-conforming finite element cochain complex based on a modified Hermite interpolation operator, which is proved to commute with the exterior derivative by means of a general commutation lemma. Adhering to a strict tensor product construction we then derive finite element complexes in higher dimensions.

• Development lengths for non-newtonian flows in pipes and tubes based on the wall shear stress

  C. De Lambride, A. Syrakos, G. Georgiou

  Test Clara Collection (1970). Vol. Computational Applied Mathematics, 3

  
  

  Abstract

  The development length needed for tube flows to re-adjust from a uniform to the fully-developed velocity profile is usually defined as the length required for the centerline velocity to reach 99% of its fully-developed value. This definition, however, may be quite inaccurate in non-Newtonian flows with almost flat velocity distributions near the centerline, since the velocity far from the axis of symmetry develops more slowly. Shear-thinning and viscoplasticity may cause the flow close to the centerline to evolve faster than that closer to the walls. Thus, alternative definitions of the development length have been proposed for viscoplastic flows. Given that blood exhibits shear thinning, we numerically solve the flow development of power-law fluids in pipes and calculate the development length as a function of the radius, determining the global development length along with the standard centerline estimate. We also consider an alternative definition, based on the evolution of the wall shear stress. Results have been obtained for values of the power-law exponent ranging from 0.

• Continuing education in the current context, approach from the nursing perspective

  N. Ríos, A. Mosca

  Collection of Métodos de Test (1970). 21

  
  

  Abstract

  Continuing education in nursing are those educational activities planned, to build the base of knowledge and experiences in order to reinforce practice, education, administration, research and theoretical development, with a view to improving the quality of care for the user. Of the health. Health institutions must undertake educational actions in order to stimulate the growth of their health personnel so that they can meet the demands of being human. Continuing education in nursing constitutes a growing need that becomes more accentuated with the increase in professional demands. Andragogy is the method that best suits the characteristics of teaching environments for continuing education. The factors that most influence the participation of nurses in these activities are the support of their supervisors and the availability of adequate continuing education programs.

• A Generalized Finite Difference-Volume Hybrid Method Applied to Shallow-Water Equations

  G. Tinoco-Guerrero, C. Test

  Collection of incidences in the generation of PDFs (2022). 1

  
  

  Abstract

  Due to the importance of the shallow-water equations in models of real-life phenomena, in recent years the study and model of problems that involve them have been the object of interest of many people. By reason of this, it is imperative to have efficient numerical methods to obtain an approximation of the solutions of the shallow-water equations. Several authors have worked in approximations using the well-known finite volume and finite element methods, nevertheless, even when these methods compute good approximations to real-life behavior, the computational cost is usually high, which could be limitation to the application of these methods. This paper presents an explicit Generalized Finite Difference-Volume Hybrid approximation to the solution of the shallow-water equations, solved on irregular regions meshed with logically rectangular grids; the numerical results show the accuracy obtained with a low-cost implementation. The proposed scheme is a hybridization of a generalized finite difference scheme with the finite volume method.

• Hidden Cost Management Model for the Continuous Improvement of Human Resources

  A. Negrón-González, G. Gemar-Castillo, M. Noda-Hernández

  Collection of Métodos de Test (1970). 19

  
  

  Abstract

  Proper identification and quantification of hidden costs of human resource management contributes to increasing business management effectiveness. Currently, in many companies the hidden costs are not reflected in their financial balance sheets, or in their financial records. The objective is to analyze the results of the application of a hidden cost management model for the continuous improvement of human resources in the hotel sector. The expectations and needs of customers have been taken into account at all times and the social and economic elements of socio-economic management have been integrated to contribute to the development of service quality in the hotel sector. Different techniques and tools have been used, such as the checklist, the balanced scorecard, the SERVQUAL model and an empirical study of which a factor analysis was carried out as a data reduction method, to obtain the correlations between more of the 57 observable variables. This study will allow reaching higher levels in job performance, in addition to an increase in work productivity and quality of service.
