  • Research of influence of speech codecs on transmission quality of the digital signal 
    Ishchanova, Zh.K.; Amochaeva, G.P.; Tussupbekova, A.K. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    The Kazakhstan telephone system of the general using contains both analog and digital segments. For a long time analog segments served for an information exchange between subscribers, however introduction of digital segments ...
  • Analysis of the procedure lcas in transport networks ngsdh 
    Zakiev, D.M.; Amochaeva, G.P.; Mursalin, R.A. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    The paper presents a procedure LCAS (Link Capacity Adjustment Scheme) - scheme of regulation of channel capacity, is built on virtual concatenation mechanism. LCAS protocol allows you to dynamically change the capacity of ...
  • The results of “vibration-seismic-module-solid massif-disturbance” system simulation modeling 
    Smirnov, Y. M.; Kenzhin, B.M.; Zhurunova, M.A. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    Paper is devoted to study of interaction of a mechanic harmonic generator – the vibration-seismic module - and a coalbed. As a result there are qualitative and quantitative dependences of distribution of elastic seismic ...
  • Hydrodynamics of hydrocyclone with built-in water injector 
    Minkov, L.; Farghaly, M.; Dueck, J. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    The paper considers the numerical simulation of 3D fluid dynamics based on the k-eps RNG model of turbulence in the hydrocyclone with the injector, containing 5 tangentially directed nozzles. The simulation results are ...
  • Nonlinear fractals and exciton formations in nanostructured semiconductors 
    Zhanabayev, Z.Zh.; Grevtseva, T.Yu. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    We suggest the fractal model for the description of exciton spectra in amorphous and porous semiconductors. Because of theirs chaotic structure the well-known analogy of exciton with hydrogen-like atom is insufficient. We ...
  • Time-resolved luminescent spectrometry of zink selenide crystals 
    Oleshko, V.I.; Vil’chinskaya, S.S.; Gorina, S.G. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    The spectral and kinetic characteristics of pulse cathodoluminescence of undoped ZnSe single-crystals grown by sublimation from the vapor phase (Davydov-Markov method) and by flux growth (Bridgman method) have been measured. ...
  • Gravitational convection in gas system Ar – N2 
    Poyarkov, I.V. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    A study has been made of the "diffusion - gravitational convection" transition boundary in an argon - nitrogen binary system at different pressures and a constant temperature gradient. Research relative influence two ...
  • About luminescent properties of monocrystals of the difficult sulfates activated by thallium 
    Baktybekov, K. S.; Myrzakhmet, M.K.; Nikl, M.; Jerry, V.; Bekmyrza, K. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    Luminescence centres in the ammonium sulphate crystals with an impurity of thallium and in the mixed crystals are explored. It is shown, that these centres are the one-charging thallium ion. Two various positions of ...
  • Superficial tension of pure metals 
    Jurov, V.M. (Publishing House of the KarSU named after E.A.Buketov, 2011)
    In work questions of experimental definition of a superficial tension of massive samples and nanoparticles pure metals are considered. The model allowing with good accuracy to define size of a superficial tension, its ...
