  • Article


  • Authors: Bui, Van Loat; Nguyen, Van Quan; Le, Tuan Anh; Tran, The Anh; Nguyen, The Nghia; Nguyen, Van Hung (2009)

  • Radioactive sources which used to study were the standardized radioactive of common monoenergetic radionuclide Cs137 and standardized multigamma Co60, Ba133, Eu152. Determination of the absolute efficiency curve and energy resolution as a function of energy of GEM40P4 HPGe spectrometer are presented in this paper.

  • In this paper, we study the systems of generalized quasiequilibrium problems which includes as special cases the generalized vector quasi-equilibrium problems, vector quasiequilibrium problems, and establish the existence results for its solutions by using fixed-point theorem. Moreover, we also discuss the closedness of the solution sets of systems of generalized quasiequilibrium problems. As special cases, we also derive the existence results for vector quasiequilibrium problems and vector quasivariational inequality problems. Our results are new and improve recent existing ones in the literature.

  • Thesis


  • Authors: Nguyen, Van Hung;  Advisor: Nguyen, Thi Hong Hanh (2018)

  • Television Audience Measurement is a popular field of study in the world but quite new for the Vietnam. The objective of the research is introduce a new and effective approach to the study of television audience to help advertiser/media agency/broadcaster understand the audience characteristics, habits, tastes… from which they can build and develop the effective and optimal communications strategies.

  • A new procedure for calculation and analysis of thermodynamic and correlation effects of bcc crystals under in fluence of dopant atom in the X-ray Absorption Fine Structure (XAFS) has been developed. Analytical expression for the Displacement-displacement Correlation Function (DCF) CR has been derived based on the derived Mean Square Relative Displacement (MSRD) 2 Ơ2 and Mean Square Displacement (MSD) u of bcc crystals containing dopant atom. Numerical calculations have been carried out for Fe doped by w and by Cr atom. They are found to be in good agreement with experiment.

  • An analytical method for calculation and evaluation of thermodynamic properties of alkali metals under the influence of impurity atom has been developed based on quantum statistical theory with correlated Einstein model. Mean square relative displacement (MSRD), effective local force constants, correlated Einstein frequency and temperature of pure alkali metals and those with impurity have been calculated and compared each to other.
