Prof. A. Medina graduated in Physics in 1990 (Universidad de Salamanca, Spain) and obtained his Ph D in 1993 working on the infrared spectroscopy of simple molecules in dense media. From then his research interests evolved towards the theoretical analysis of different thermal engines, specially the computer simulation of internal combustion engines and power plants. He spends his spare time practicing several outdoors sports as cycling and mountaineering. He is also a passionate traveller and reader.   Assistant Professor P.L. Curto-Risso obtained a degree in Mechanical Engineering in 2004 at Universidad de la República (Montevideo, Uruguay) and his Ph D in  2009 at Universidad de Salamanca (Spain), working on the numerical simulation of internal combustion engines. His research interests involve computational analysis of different thermal engines and topics related with combustion phenomena and heat transfer.   Prof. A. Calvo Hernández obtained his Ph D in Physics in 1985 (Universidad de Salamanca, Spain). His present research interests are focused on the analysis of unified thermodynamic aspects of diverse energy converters. His preferred spare time activities are walking and bird watching.   Lev Guzmán-Vargas is Associate Professor at National Polytechnic Institute, Mexico. He did his doctoral work (Ph. D., 2002) in nonlinear analysis of time series. Lev has worked in the areas of time series analysis, nonlinear dynamics and complex systems. He is also interested in exploring the organizational properties of complex networks with applications to physical, biological and social systems. He lives in Mexico City.   Fernando Angulo-Brown is full Professor at Escuela Superior de Física y Matemáticas, Instituto Politécnico Nacional (México City). His main fields of interest are non-equilibrium thermodynamics and seismology. He has been physics teacher during more than forty years and advised bachelor, master or doctorate thesis to more than fifty students.  Asok K. Sen received his bachelor’s degree in Mechanical Engineering from the Indian Institute of Technology, Kharagpur, India, and his master’s degree also in Mechanical Engineering from the University of Minnesota, USA. He received his Ph.D. in Theoretical and Applied Mechanics from Cornell University, USA. He has held visiting positions at the California Institute of Technology, Northwestern University, Cornell University, and the University of Toronto. Currently, he is a professor of Applied Mathematics at Indiana University. His research interests are in the application of various signal processing techniques to the analysis of nonstationary time series arising in the fields of energy and environment.
