A full energy range primary radiation damage model is presented here. It based on the athermal recombination corrected displacements per atom (arc-dpa) but includes a proper treatment of near threshold conditions for metallic materials. Both ab initio (AIMD) and classical molecular dynamics (MD) simulations are used here various metals with body-centered cubic (bcc), face-centered (fcc), hexago...

Full-spectrum ranging from sub-6 GHz to THz and visible light will be exploited in 6G order reach unprecedented key-performance-indicators. However, an extraordinary amount of energy consumed by network infrastructure, while functions massively deployed Internet Everything (IoE) devices are limited embedded batteries. Therefore, self-sustainable (ESS) is proposed this article. First all, it may...

To stabilize greenhouse gas concentrations at an equivalent doubling, CO2 emissions must be limited to 5 PgC y in 2050, compared to 8 PgC y today. This will require the decarbonization of world energy supply, in which fossil fuels, which today account for 85% of energy supply, are replaced by carbon-free sources. Only five sources are capable of supplying a substantial fraction of the required ...

Background: The characteristics of secondary neutrons in a high energy radiation therapy room were studied using the MCNPX Monte Carlo (MC) code. Materials and Methods: Two MC models including a model with full description of head components and a simplified model used in previous studies were implemented for MC simulations. Results: Results showed 4-53% difference between full and wit...

The Potential Energy Surface PES of (H2)2 dimer has been investigated, using five simple rigid rotor models. These models are called: head to head, symmetric side to side, L , steplike and T model. All calculations were done at two levels of ab initio  methods: MP2(Full) and QCISD (T,Full) using cc-pVTZ basis set at singlet state of spin multiplicity. The results of scanning PES were then fitte...

In this paper, an intelligent control strategy based on combination of the “flatness based control technique” and the “perturbation and observation (P&O) MPPT algorithm” is developed and investigated to control a hybrid electric energy source (HEPS). This EHPS is composed of a fuel cell system (FC) and a solar panel (SP), as the main source and a supercapacitor bank (SC), as the auxiliary sourc...
