Mass transfer is of great importance in engineering, including the analysis of new ecological building materials. The estimation of parameters or functions appearing in mathematical formulations of problems in nature, by using measurements of some response of the system and the calculated correspondent dependent variable of the model, is an inverse problem. Within the last 50 years, the application of inverse problems for the characterization of materials became a practical tool with many important applications. Several techniques have been developed for the solution of inverse problems, including those based on inference of the distributions of the sought parameters within the Bayesian framework of statistics. This presentation is based on a recent publication by the authors , where an Approximate Bayesian Computation (ABC) technique has been applied for model selection and calibration of water sorption in a wood fibre material. Eight competing models have been considered to represent the experimental data of the moisture content in the material samples that were measured with a DVS equipment. The moisture adsorption model proposed in this work was the one selected with the ABC technique and could very accurately represent the experimental data.

Biography
Prof. Helcio Rangel Barreto Orlande obtained his B.S. in Mechanical Engineering from the Federal University of Rio de Janeiro (UFRJ) in 1987 and his M.S. in Mechanical Engineering from the same University in 1989. After obtaining his Ph.D. in Mechanical Engineering in 1993 from North Carolina State University, he joined the Department of Mechanical Engineering of UFRJ, where he was the department head during 2006 and 2007. His research areas of interest include the solution of inverse heat and mass transfer problems, as well as the use of numerical, analytical and hybrid numerical-analytical methods of solution of direct heat and mass transfer problems. He is the co-author of 4 books and more than 350 papers in major journals and conferences. He is a member of the Scientific Council of the International Centre for Heat and Mass Transfer and a Delegate in the Assembly for International Heat Transfer Conferences. He serves as an Associate Editor for the journals Heat Transfer Engineering, Inverse Problems in Science and Engineering, High Temperatures – High Pressures and International Journal of Thermal Sciences.
