Abstract The paper deals with the random time-dependent oligopolistic market equilibrium problem. For such a problem firms’ point of view has been analyzed in Barbagallo and Guarino Lo Bianco (Optim. Lett. 14 : 2479–2493, 2020) while here policymaker’s is studied. dynamic optimal control conditions are expressed by means an inverse stochastic variational inequality which proved to be equivalent...

Nanocomposite of polyaniline (PAn) containing nanometre size Sb2O3 was prepared in aqueous media in situ chemical oxidative polymerization method at room temperature in the presence of hydroxypropylcellulose (HPC) as a surfactant. The ability of product to removal of lead ions from aqueous solution was studied. The chemical structure and morphology were studied by fourier transform infrared (FT...

For a sequence of nite Markov chains L(N) we introduce the notion of \conver-gence time to equilibrium" T(N). For sequences that are obtained by truncating some countable Markov chain L we nd the convergence time to equilibrium in terms of Lyapunov function of Markov chain L. We apply this result to queue-ing systems with a limited number of customers: a priority system with several customer ty...

in this paper, a new approach based on game theory has been proposed to multi responses problem optimization. game theory is a useful tool for decision making in the conflict of interests between intelligent players in order to select the best joint strategy for them through selecting the best joint desirability. present research uses the game theory approach via definition of each response as ...

the electronic absorption spectral line shape of a diatomic molecule with harmonic potential curves is calculated using the time correlation function formalism. both the equilibrium shift and the frequency shift of the two linking electronic states ate taken into account. the spectrum is also calculated using the cumulated expansion which is related to the correlation function of the time-depen...

industrial wastewater included the dyes one of the important sources of environmental pollution that founded in loom wastewater which are harmful for human health and environment. therefore, the purpose of this research was investigated removal of rb5 dye from aqueous solution by using of adsorption onto activated red mud as an cheap adsorbent. this research was experimental- laboratorial study...
