Analysis of finite element approximation of evolution problems in mixed form
No full textThis paper deals with the finite element approximation of evolution problems in mixed form. Following [D. Boffi, F. Brezzi, L. Gastaldi, Math. Comp. 69 (2000), pp.121-140], we handle separately two types of problems. A model for the first case is the heat equation in mixed form, while the time dependent Stokes problem fits within the second one. For either case, we give sufficient conditions for a good approximation in the natural functional spaces. The results are not obvious in the first situation. In this case, the well-known conditions for the well-posedness and convergence of the corresponding steady problem are not sufficient for the good approximation of the time dependent problem. This issue is demonstrated with a numerical (counter-) example and justified analytically
Stability Results for the Finite Element Approach to the Immersed Boundary Method
No full textThe immersed boundary method in its original formulation, introduced by Peskin in [9], exhibits a high degree of numerical stiffness. A finite element approach was proposed by Boffi et al. [1] and further developed in Boffi et al. [2,3] to solve some of the difficulties arising from the original formulation. We present a stability analysis for the two dimensional case with some numerical tests which show how to choose the numerical parameters in order to obtain optimal stability

Boffi (B): Evaluating Foreign Market Profitability
No full textPowered by the past success, Boffi has expanded into approximately 60 countries (see Boffi A). Now, it faces important questions concerning its future international growth. This case focuses on the decision by Boffi, a furniture manufacturer from Italy, to identify new export markets (e.g. India) and to assess foreign markets profitability. The teaching objectives of the case are: to understand the issues in deciding whether to enter a new market and how a decision can affect the company economic profile, to discover the range of issues to be addressed in entering a foreign market

Boffi (A): Managing Internationalization in Luxury Goods
No full textThe case examines in depth the internationalization process of a niche company in the luxury market. Its approach leverages the high quality standards of production, the Made in Italy reputation in this field, the selected and controlled network of retailers. While the industry Boffi belongs to is quite sensitive to differences among countries, Boffi does not provide any particular adaptation of models. However, each specific kitchen is designed according to the requirements of high-spending customers. This is a typical case of a SME that exports what is locally produced without a sophisticated assessment system of foreign markets attractiveness and profitability
Local mass conservation of Stokes finite elements
No full textIn this paper we discuss the stability of some Stokes finite elements. In particular, we consider a modification of Hood–Taylor and Bercovier–Pironneau schemes which consists in adding piecewise constant functions to the pressure space. This enhancement, which had been already used in the literature, is driven by the goal of achieving an improved mass conservation at element level. The main result consists in proving the inf-sup condition for the enhanced spaces in a general setting and to present some numerical tests which confirm the stability properties. The improvement in the local mass conservation is shown in a forthcoming paper (Boffi et al. In: Papadrakakis, M., Onate, E., Schrefler, B. (eds.) Coupled Problems 2011. Computational Methods for Coupled Problems in Science and Engineering IV, Cimne, 2011) where the presented schemes are used for the solution of a fluid-structure interaction problem
