    • Analysis of access to the electricity transmission network using information technologies in some countries 

      Azieva, Gulmira; Kerimkhulle, Seyit; Turusbekova, Umut; Alimagambetova, Ainagul; Niyazbekova, Shakizada (E3S Web of Conferences, 2021)
      The role of information technology is especially great in strategic sectors of the economy, one of which is energy. After all, the more complex the product, the more acutely it needs more automation of the processes taking place in it. The main informational tasks of power generation are the automation of technological process systems and control over the installed ...

    • A method for planning the trajectory of a mobile robot in an unknown environment with obstacles 

      Tebueva, Fariza; Pavlov, Andrey; Satybaltina, Dina (E3S Web of Conferences, 2021)
      The known algorithms for planning the trajectory of movement of mobile robots in an unknown environment have high computational complexity or do not allow finding the trajectory that is optimal along the length of the path, while maintaining a safe distance from obstacles. The aim of the work is to increase the efficiency of solving the problem of planning the trajectory ...

    • A method for extracting oil from a field with hard-to-recover reserves based on systems analysis methodology 

      Ospanov, Yerbol; Smailova, Ulmeken; Mukhametov, Yeldos; Zhapar, Botagoz; Zhienbek, Araylym; Khidoyatov, Salavat; Nazarov, Rashid (E3S Web of Conferences, 2024-03)
      The article examines the problems of solving the problem of optimizing oil production processes from a field with hard-to-recover oil reserves, characterized by shortages and fuzziness of the initial information. Equations for the continuity of the mass of matter in an oil reservoir have been derived for various cases. As a result of the study, by combining and modifying ...

    • About the model of railway transport management in Russia 

      Bykadorov, Sergey; Arpabekov, Muratbek; Khudayberganov, Sakijan; Suyunbayev, Shinpolat; Khusenov, Utkir; Makhmudovna, Mafratkhon (E3S Web of Conferences, 2023)
      Structural reform of railway transport of Russia realized within the last 20 years is synthesized descriptive and standard approaches to the analysis of the large-scale institutional project. Quantitative indices and the qualitative expert judgments testifying to ambiguity of results of long-term reforming are given. The conclusion is drawn that Reform did not lead to ...

    • LANDSLIDE SUSCEPTIBILITY MAPPING USING ANALYTICAL HIERARCHY PROCESS AND GEOGRAPHICAL INFORMATION SYSTEM IN RUDNY ALTAI REGION, EAST KAZAKHSTAN 

      ZHANABAYEV, Dauren; DZHANALEEVA, Kulchikhan; ATASOY, Еmin; EFE, Recep (Geographia Technica, 2024)
      Landslides are one of the important natural threats that often cause loss of life and property in Kazakhstan. One of the regions affected by landslides of different types and sizes that occur for different reasons in the country is the Rudny Altay Region in the east of Kazakhstan. This study deals with the landslide susceptibility assessment using remote sensing methods in ...

    • Experimental study on mitigating wind erosion of calcareous desert sand using spray method for microbially induced calcium carbonate precipitation 

      Dagliya, Monika; Satyam, Neelima; Sharma, Meghna; Garg, Ankit (Journal of Rock Mechanics and Geotechnical Engineering, 2022)
      Wind erosion is one of the significant natural calamities worldwide, which degrades around one-third of global land. The eroded and suspended soil particles in the environment may cause health hazards, i.e. allergies and respiratory diseases, due to the presence of harmful contaminants, bacteria, and pollens. The present study evaluates the feasibility of microbially induced ...

    • Alpha-decay induced shortening of fission tracks simulated by in situ ion irradiation 

      Li, Weixing; Cheng, Yuanyuan; Feng, Lei; Niu, Jingjing; Liu, Yingxin; Skuratov, Vladimir A.; Zdorovets, Maxim V.; Boatner, Lynn A.; Ewing, Rodney C. (Geochimica et Cosmochimica Acta, 2021)
      The diffusion of defects (e.g., vacancies and interstitials) and elements used for dating (e.g., He and Pb) in a mineral structure is a thermal process: This is the primary assumption used to determine the age and thermal history of minerals. For instance, thermal history reconstruction, through the number and length distribution of tracks produced by spontaneous fission of 238U, ...

    • Non-minimal geometry–matter couplings in Weyl–Cartan space–times: f (R, T , Q, Tm) gravity 

      Harko, Tiberiu; Myrzakulov, Nurgissa; Myrzakulov, Ratbay; Shahidi, Shahab (Physics of the Dark Universe, 2021)
      We consider an extension of standard General Relativity in which the Hilbert–Einstein action is replaced by an arbitrary function of the Ricci scalar, nonmetricity, torsion, and the trace of the matter energy–momentum tensor. By construction, the action involves a non-minimal coupling between matter and geometry. The field equations of the model are obtained, and they lead to the ...

    • Unifying an asymmetric bounce to the dark energy in Chern–Simons F(R) gravity 

      Odintsov, Sergei D.; Paul, Tanmoy; Banerjee, Indrani; Myrzakulov, Ratbay; SenGupta, Soumitra (Physics of the Dark Universe, 2021)
      We propose a cosmological scenario in which the universe undergoes through a non-singular bounce, and after the bounce, it decelerates having a matter-like dominated evolution during some regime of the deceleration era, and finally at the present epoch it evolves through an accelerating stage. Our aim is to study such evolution in the context of Chern–Simons corrected F(R) ...

    • Strength of the singularities, equation of state and asymptotic expansion in Kaluza–Klein space time 

      Samanta, G.C.; Goel, Mayank; Myrzakulov, R. (New Astronomy, 2018)
      In this paper an explicit cosmological model which allows cosmological singularities are discussed in Kaluza–Klein space time. The generalized power-law and asymptotic expansions of the baro-tropic fluid index ω and equivalently the deceleration parameter q, in terms of cosmic time ‘t’ are considered. Finally, the strength of the found singularities is discussed.
