Modeling Interactions between Graphene and Heterogeneous Molecules

  • Kyle Stevens,
  • Thien Tran-Duc,
  • Ngamta Thamwattana and
  • James M. Hill

The Lennard–Jones potential and a continuum approach can be used to successfully model interactions between various regular shaped molecules and nanostructures. For single atomic species molecules, the interaction can be approximated by assumin...

Classification of Categorical Data Based on the Chi-Square Dissimilarity and t-SNE

  • Luis Ariosto Serna Cardona,
  • Hernán Darío Vargas-Cardona,
  • Piedad Navarro González,
  • David Augusto Cardenas Peña and
  • Álvaro Ángel Orozco Gutiérrez

The recurrent use of databases with categorical variables in different applications demands new alternatives to identify relevant patterns. Classification is an interesting approach for the recognition of this type of data. However, there are a few a...

Simulation of Diffusion Bonding of Different Heat Resistant Nickel-Base Alloys

  • Albert R. Khalikov,
  • Evgeny A. Sharapov,
  • Vener A. Valitov,
  • Elvina V. Galieva,
  • Elena A. Korznikova and
  • Sergey V. Dmitriev

Currently, an important fundamental problem of practical importance is the production of high-quality solid-phase compounds of various metals. This paper presents a theoretical model that allows one to study the diffusion process in nickel-base refra...

A Discrete Particle Swarm Optimization to Solve the Put-Away Routing Problem in Distribution Centres

  • Rodrigo Andrés Gómez-Montoya,
  • Jose Alejandro Cano,
  • Pablo Cortés and
  • Fernando Salazar

Put-away operations typically consist of moving products from depots to allocated storage locations using either operators or Material Handling Equipment (MHE), accounting for important operative costs in warehouses and impacting operations efficienc...
