We give a new criterion guaranteeing existence of model structures left-induced along functor admitting both adjoints. This works under the hypothesis that induces idempotent adjunctions at homotopy category level. As an application, we construct on cubical sets, prederivators, marked simplicial sets and spaces modeling <mml:math xmlns:mml="http://www...

carbon nanotubes (cnts) are specific structures with valuable characteristics. in general, the structure of each nanotube is defined by a unique chiral vector. in this paper, different structures of short single-walled cnts are simulated and their mechanical properties are determined using finite element method. for this aim, a simple algorithm is presented which is able to model the geometry o...

for the analysis of structures, the first step consists of configuration processing followed by data generation. this step is the most time consuming part of the analysis for large-scale structures. in this paper new graph products called triangular and circular graph products are developed for the formation of the space structures. the graph products are extensively used in graph theory and co...
