in this paper, we propose a sensitivity analysis for evaluating the effectiveness of recovery solutions in the case of disturbed rail operations. indeed, when failures or breakdowns occur during daily service, new strategies have to be implemented so as to react appropriately and re-establish ordinary conditions as rapidly as possible. in this context, the use of rail simulation is vital: for e...

we have investigated structure and electronic properties of au and si liner chains using the firstprinciplesplane wave pseudopotential method. the transport properties and conductance of these twoliner chains are studied using landauer approaches based on density functional theory (dft). weobtain density of states and band gap using kohn-sham and wannier functions as well as quantumconductivity...

Developed an integrated intellectual computerized system of ecological-economic monitoring, modeling, and managing the life cycle of the products of technogenic enterprises of transport engineering, which is presented in the form of a 3-equation structure, functioning in conditions of instability. The proposed paradigm system life cycle management applicable to any other control system of large...

the two stable isotopes of hydrogen, protium (1h) and deuterium (2h) differ in their physicochemical nature. deuterium-depleted water (ddw) significantly inhibited the growth rate of different tumor cell lines in culture media and xenotransplanted mda-mb-231, mcf-7 human breast adenocarcinomas and pc-3 human prostate tumors in vivo. the apoptosis-triggering effect of ddw was demonstrated both i...

 In recent years, semiconductor nanostructures have become the model systems of choice for investigation of electrical conduction on short length scales. Quantum transport is studied in a two dimensional electron gas because of the combination of a large Fermi wavelength and large mean free path. In the present work, a numerical method is implemented in order to contribute to the understanding ...
