The modal split model is one of the steps of the classical four-step travel demand planning. Predictive, descriptive, and prescriptive modal split models are essential to make a balance between travel demand and supply. To calibrate these models, it is necessary to detect and employ influential independent variables that are related to characteristics of travel modes, individual and family attr...

dft and qtaim computations have been performed on numbers of pure nitrogen cluster speciesi.e. nn (n = 4, 6) for investigating the structure and bonding. this study is critical since thesemolecules have been nominated as the good synthetic targets of high energy materials (hem).0nthe other hand the decomposition mechanism is closely depends on the bonding pattern. thislatter concept was searche...

En Alemania, existe una gran tradición de proyectos modelización, llevados a cabo por diferentes universidades todo el país. Desde 2001, grupo trabajo Didáctica las Matemáticas del Departamento Educación la Universidad Hamburgo ha llevado modelización. este artículo se describe en detalle proyecto actual, Jornadas Modelización Hamburgo. Uno los objetivos es posibilitar que alumnos adquieran exp...
