    Design and construction of a transducer for bite force registration.
    (ELSEVIER SCI LTD, 2009-05-29) Isaza JF; Throckmorton GS; Roldán SI; Universidad EAFIT. Departamento de Ingeniería Mecánica; Bioingeniería GIB (CES – EAFIT)
    This study describes the development of a system for quantification of human biting forces by (1) determining the mechanical properties of an epoxy resin reinforced with carbon fiber, (2) establishing the transducer's optimal dimensions to accommodate teeth of various widths while minimizing transducer thickness, and (3) determining the optimal location of strain gages using a series of mechanical resistance and finite element (FE) analyses. The optimal strain gage location was defined as the position that produced the least difference in strain pattern when the load was applied by teeth with two different surface areas. The result is a 7.3-mm-thick transducer with a maximum load capacity beyond any expected maximum bite force (1500N). This system includes a graphic interface that easily allows acquisition and registration of bite force by any health-sciences or engineering professional.

    Solution of the wave equation for an oscillating punctual source by means of the finite elements method
    (SPIE-INT SOC OPTICAL ENGINEERING, 2016-01-01) Marín-Suárez, M.; Marín-Suárez, M.; Universidad EAFIT. Departamento de Ciencias; Lógica y Computación
    Finite Elements Method (FEM) and Finite Differences Method (FDM) in the Euler implicit approach, were used in order to determine the bi-dimensional electromagnetic field of an oscillating punctual source inside a square geometry with three reflective boundaries and an absorbing one. Although the main approach consist in solving the wave equation for the electric field, it was decided to use the approach of electromagnetic potentials V and A because those potentials give a simpler solution for both, the electric and magnetic fields. Besides, a comparison with theory was made, solving for an electromagnetic field without boundaries produced by an oscillating punctual source.
