(American Institute of Physics, 2011-12)Although vacuum arcs were first identified over 110 years ago, they are not yet well understood. We have since developed a model of breakdown and gradient limits that tries to explain, in a self-consistent way: arc triggering, ...
-
(Nazarbayev University School of Sciences and Humanities, 2020-04-30)In this project, the bivariate dependence structures between the Japanese Yen, Chinese Yuan, and Hong Kong Dollar exchange rates against the US Dollar are studied by using time-invariant and time-varying copulas. The ...

(International Scientific and Practical Conference "Geosystemic approach to the study of the natural environment of the Republic of Kazakhstan", 2018-04-13)The Syrdarya river basin in Central Asia is facing a strong degradation of ecosystems and water quality deterioration mainly attributed to intensive agriculture. Predicted population growth and land use change call for ...
-
(Fluids, 2021-02-22)The numerical investigation of the interpenetrating flow dynamics of a gas injected into a homogeneous porous media saturated with liquid is presented. The analysis is undertaken as a function of the inlet velocity, ...
-
(Nazarbayev University School of Engineering and Digital Sciences, 2021-05)The numerical analysis of the gas displacing immiscible liquid in 2D homogenous porous media is demonstrated. The model is analyzed in terms of different flow and pore geometry specifications, namely capillary number (Ca), ...
-
(Nazarbayev University School of Engineering and Digital Sciences, 2021-07)Implementation of switching interest inside the all-optical area is one of the maximum important elements inside the issue of present-day high-pace and secured conversation technology. Micro-ring Resonator (MRR) primarily ...
-
(Nazarbayev University, 2014)The graphene-based resonator and its application to mass sensing based on nonlinear waves have been poorly studied numerically [1]. The project's main objective is to model and understand how graphene behave in free and ...
-
(MANUFACTURING TECHNOLOGY, 2021-06)A new Coupler Critical Dimensions (CCD) approach to define mobility criteria (crank, rocker conditions, or existence) for linkage mechanisms has been presented in this paper. The concept is critical to design and analyze ...
-
(Nazarbayev University School of Science and Technology, 2016-05)Intraocular Pressure (IOP) is a main factor for the diagnosis of glaucoma. In this report, the kinematic viscoelastic corneal models, specifcally the Maxwell and the Kelvin-Voight models, of human eye ball will be proposed ...
-
(arXiv preprint arXiv:1410.6501, 2014)Comsol finite element technique was applied to study heating and cooling of a microspot on the cathode surface. The reasons why there seems to be no common model for vacuum arcs, in spite of the importance of this field ...
-
Modeling of Material Removal Rate and Surface Roughness Generated during Electro-Discharge Machining (MDPI, 2019-06)This study reports on the numerical model development for the prediction of the material removal rate and surface roughness generated during electrical discharge machining (EDM). A simplified 2D numerical heat conduction ...
-
(Nazarbayev University, 2013)This is the first instance when the Caspian Region fuel and energy complex is modeled with sufficiently detailed representation of both supply and demand sides (bottom-up approach). The technological description of the ...
-
(arXiv preprint arXiv:1003.1736, 2010)We describe breakdown in 805 MHz rf accelerator cavities in terms of a number of self-consistent mechanisms. We divide the breakdown process into three stages: (1) we model surface failure using molecular dynamics of ...

(arXiv preprint arXiv:1006.3770, 2010)
-
(Proceedings of PAC2013, Pasadena, 2013)We describe our vacuum arc model, which divides breakdown into four stages: trigger, plasma formation, plasma evolution and surface damage. We have modeled all four stages numerically and find that the properties of surface ...
-
(Springer, 2021-01-03)Enhanced oil recovery (EOR) is a proven method to increase oil production from the brown fields. One of the efficient EOR methods is injecting surfactants to release the trapped oil. However, few unconsolidated behaviours ...
-
(Nazarbayev University, 2014)The project's main objective is the modeling of the electricity sector in Kazakhstan. The demand growth in the last years could be compensated so far by reactivation and retrofit of existing old reserve capacities from ...
-
(Nazarbayev University School of Engineering and Digital Sciences, 2018-03)Globally, buildings account for one third of final energy consumption and are a significant source of CO2 emissions. Concerns with unsustainable use of energy in buildings, growing greenhouse gases emissions and energy ...
-
(Mechanism and Machine Theory, 2017-12-01)Abstract Human shoulder movements involve motions at four different articulations, one of which is the contact between the scapula bone and the ribcage. The shoulder biomechanical models become less reliable when the ...
-
(Drustvo Psihologa Srbije, 2019-10-01)This study aims to determine the relationship between psychological capital and job satisfaction, organizational commitment, motivation, and the intent to leave. The sample of this study consists of 323 teachers in 25 ...
