(NURIS; Energetic Cosmos Laboratory, 2019-03-05)We examine the Pantheon supernovae distance data compilation in a model independent analysis to test the validity of cosmic history reconstructions beyond the concordance ΛCDM cosmology. Strong deviations are allowed by ...
-
(Nazarbayev University School of Sciences and Humanities, 2020)Ceramic paste extrusion process, such as 3D printing, is commonly used for fabricating high quality products, like catalyst pellets for heterogeneous catalytic reactors, porous catalyst for cleaning gas released from an ...
-
(Nazarbayev University School of Sciences and Humanities, 2020-05-01)There has been great interest in membrane reactors over the last decades. The limitation of selectivity and yield of certain products in chemical reactions is an important and not sfficiently solved problem in the field ...
-
(Nazarbayev University School of Sciences and Humanities, 2021-05)Diffusion-reaction processes in chemical reactors are often modelled by differential equations of diffusion-reaction type that describe the change in time and space of concentrations of chemical species. In this work, ...
-
(School of Sciences and Humanities, 2023-07)Microelectromechanical systems (MEMS) have emerged as a revolutionary technology, enabling the development of miniaturized devices with diverse functionalities and superior performance. Among the essential components of ...
-
(Nazarbayev University, 2014)The project objectives are to model the energetic configuration of a Smart House in a numerical platform (e.g., HOMER Energy™ software), to validate the numerical predictions of technical performance with experimental ...
-
(Proceedings of the 7th International Conference on Nanochannels, Microchannels and Minichannels ICNMM2009 June 22-24, 2009, Pohang, South Korea, 2009-06-22)The fluid delivery process through a rollerball device is investigated by means of physical modeling and numerical simulations. The microfluidic device is intended to deliver liquid above a substrate interacting with the ...
-
(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 ...
