(Financial Management, 2019)In model-free out-of-sample tests, we find that the optimal portfo lio of a utility maximizing investor trading in the S&P500 Index, cash, and index options bought at ask and written at bid prices stochas tically dominates ...
-
(CAMBRIDGE UNIV PRESS, 2019-09-16)Can nondemocratic leaders initiate a crackdown against mass protesters and suffer little in the way of political-reputational costs? In conceptualizing a "crackdown" as a government-orchestrated violent restriction of civil ...
-
(Physics Letters A, 2017-01-30)Abstract It is well-known that the partition function can consistently be factorized from the canonical equilibrium distribution obtained through the maximization of the Shannon entropy. We show that such a normalized and ...
-
(IEEE, 2017)Obtaining anomalous reflection and transmission (namely propagation along directions different from those predicted by Snell’s law) is investigated for plane waves impinging on a planar periodic metasurface composed of two ...
-
(Nazarbayev University School of Engineering and Digital Sciences, 2021-05)The path towards green economy led people to rethink the idea of energy utilization and generation. To reduce the amount of produced green gas emissions, nowadays, people are installing renewable energy generation units ...

MIXED DIMENSIONAL PEROVSKITES HETEROSTRUCTURE FOR HIGHLYEFFICIENT AND STABLE PEROVSKITE SOLAR CELLS (Solar RRL, 2021)Heterojunctions constructed upon multidimensional perovskites (1D/3D or 2D/3D) has emerged as an effective approach to improve the photovoltaic performance and stability of perovskite solar cells (PSCs). Herein, 1D trimethyl ...
-
(Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy, 2015)From the works of Anne Rice and Stephen King to films on vampires and the walking dead, the appeal of vampirism has become a cultural phenomenon in the United States, especially to young people. In the modern era where the ...
-
(Nazarbayev University, 2013)The project points to the national needs in two respects both Energy (Oil and Gas) and Environmental issues, which are going to be presented through Expo 2017. It will tackle optimisation of the new High Efficiency Video ...
-
(IFAC Proceedings Volumes, 2012-01-01)Abstract This paper describes a MATLAB Toolbox for the integrated design of Model Predictive Control (MPC) state-feedback control laws and the digital circuits implementing them. Explicit MPC laws can be designed using ...
-
(School of Engineering and Digital Sciences, 2023-11-30)This research, conducted as part of a PhD program at Nazarbayev University, investigates advanced control methods for electric engines, with a focus on Wind Energy Conversion Systems (WECS), in pursuit of sustainable and ...
-
(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 ...
