  • Raziyev, Yesset; Garifulin, Ramil; Shintemirov, Almas; Do, Ton Duc (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2019)
    This paper introduces the development of a one-degree-of-freedom (1DOF) power assist device that helps to lift objects and facilitate the operator's job. The existing designs were examined for different control approaches ...
  • Ruzhansky, Michael; Suragan, Durvudkhan; Sabitbek, Bolys (SPRINGER-VERLAG ITALIA SRL, 2019-01)
    In this paper, generalised weighted Lp-Hardy, Lp-Caffarelli-Kohn-Nirenberg, and Lp-Rellich inequalities with boundary terms are obtained on stratified Lie groups. As consequences, most of the Hardy type inequalities and ...
  • Ruzhansky, Michael; Suragan, Durvudkhan (SUOMALAINEN TIEDEAKATEMIA, 2019)
    We prove a range of critical Hardy inequalities and uncertainty type principles on one of most general subclasses of nilpotent Lie groups, namely the class of homogeneous groups. Moreover, we establish a new type of critical ...
  • Kurmanbayeva, Indira; Mentbayeva, Almagul; Sadykova, Almira; Adi, Akylbek; Mansurov, Zulkhair; Bakenov, Zhumabay (Institute of Combustion Problems, 2019)
    This paper reports the synthesis of the silica (SiO2) from Kyzylorda rice husk (RH) and investigation of its electrochemical behaviour as an anode material for the lithium-ion battery. Rice husk, considered as agricultural ...
  • Lee, Moonsang; Yoon, Dockyoung; Lee, Uk Jae; Umirov, Nurzhan; Mukanova, Aliya; Bakenov, Zhumabay; Kim, Sung-Soo (Frontiers Media, 2019-07)
    The electrochemical performances of lithium-ion batteries with different lattice-spacing Si negative electrodes were investigated. To achieve a homogeneous distribution of impurities in the Si anodes, single crystalline ...
  • Li, Haipeng; Yang, Shuang; Zhao, Yan; Tan, Taizhe; Wang, Xin; Bakenov, Zhumabay (Hindawi, 2019)
    ZnO has attracted considerable attention as electrode material in lithium-ion battery (LIB) due to its theoretically high capacity. However, poor electronic conductivity and huge volumetric changes during cycling limit its ...
  • Lee, Min-Ho; Kwon, O-Yeon; Kim, Yong-Jeong; Kim, Hong-Kyung; Lee, Young-Eun; Williamson, John; Fazli, Siamac; Lee, Seong-Whan (Oxford University Press, 2019-05)
    Background Electroencephalography (EEG)-based brain-computer interface (BCI) systems are mainly divided into three major paradigms: motor imagery (MI), event-related potential (ERP), and steady-state visually evoked ...
  • Li, Baoe; Sun, Zhenghao; Zhao, Yan; Bakenov, Zhumabay (MDPI, 2019-08)
    The commercialization of Lithium-sulfur batteries was limited by the polysulfide shuttle effect, and modifying the routine separator was an effective method to solve this problem. In this work, a novel hierarchically porous ...
  • Salimidelshad, Yaser; Moradzadeh, Ali; Kazemzadeh, Ezatallah; Pourafshary, Peyman; Majdi, Abbas (KEAI PUBLISHING, 2019-06)
    To examine the effect of pressure on pore structure and petrophysical properties of carbonate rock, the porosity, permeability, CT scanning, SEM and elastic wave velocity of two carbonate core plug samples from an oilfield ...
  • Kucukkececi, Cihan; Yazici, Adnan (Institute of Electrical and Electronics Engineers, 2019-05-24)
    Wireless Multimedia Sensor Networks (WMSN), for object tracking, have been used as an emerging technology in different application areas, such as health care, surveillance, and traffic control. In surveillance applications, ...
  • Kominis, Yannis; Choquette, Kent D.; Bountis, Anastassios; Kovanis, Vassilios (Institute of Electrical and Electronics Engineers, 2019-02)
    We consider the properties of the small-signal modulation response of symmetry-breaking phase-locked states of twin coupled semiconductor lasers. The extended stability and the varying asymmetry of these modes allows for ...
  • Scarborough, Daniel (RUSSIAN PRESIDENTIAL ACAD NATL ECONOMY & PUBLIC ADM, 2019)
    In the months after the February Revolution, the Church was convulsed by a general revolt against ecclesiastical authority. The Church survived this revolt, and organized an " All- Russian Council ( Sobor)" from September ...
  • Kinyondo, Abel; Pelizzo, Riccardo (Otoritas, 2019)
    The literature has repeatedly emphasized that citizen participation is requisite for good governance. Indeed, when citizens participate in various public activities, they can voice their demands, they can invite the ...
  • Khrustalev, D.; Yedrissov, A.; Shishlova, Y.; Tyagunova, O.; Ilyassov, Baurzhan; Kurbanova, Aliya (Institute of Combustion Problems, 2019)
