The article is focused at analyzing the study of the reviewed amorphous chalcogenide thermal properties and studying the recrystallized layer photoconductivity spectra for cadmium telluride of various types. Sintered CdTe layers were obtained by spraying the aqueous suspension onto a heated ceramic substrate. The obta…
This paper presents a novel method which is called spiral tube damping bus-bar to suppress VFTO (very fast transient overvoltage) in GIS. The suppressing mechanism of the new method to restrain VFTO is analyzed. And the structure characteristics of damping bus-bar is introduced as well. Furthermore, a 550kV GIS test p…
This paper compares non-chemical equilibrium effects in decaying arc in different gases and various conditions. The influences of the gas flow rate, the arc current, the pressure and the gas medium were investigated on the non-chemical equilibrium behavior. By increasing the arc current and the nozzle pressure, the no…
The synthesis of multi-mode regulators requires to determine of the modes of operation of control objects, taking into account the features of the processes occurring in a given region of phase space. For each mode, its own version of the control law is provided, which leads to the problem of reasonable selection of t…
This report describes experimental results on DC interruption for three experiments: (1) silica-sand filling (designation: Silica), (2) polymer cylinder installation without silica-sand filling (designation: P5-Air), and (3) polymer cylinder installation with silica-sand filling (designation: P5-Silica). The shape of…
Sulfur hexafluoride (SF6), a greenhouse gas, is used as an insulating medium for power equipment due to its excellent insulating properties. However, as global warming and climate change become a global concern, the development of products that minimize the environmental impact is increasing, and SF6 replacement gas i…
Various designs of composite materials with a and the description of methods for their manufacture and control are given. The possibilities of computed tomography for the analysis of the internal structure of composite products are shown. A technique has been developed for determining defects and porosity in areas of…
Abstract The effect of valence molecular orbitals on the nature of the chemical bond of the p-metal ion with chelate ligands in Be(acac)2, Mg(acac)2 and zinc Zn(acac)2 was studied by theoretical methods. The effect of the substitution of atoms and functional groups in the ligands on the chemical bond was estimated. Fo…
Abstract In this paper, an adaptation variant of the “deformation model” is proposed for estimating the parameters of the stress-strain state of a reinforced concrete bar element with flexible discrete reinforcement, taking into account the deplanation of concrete and the features of contact interaction between reinfo…

Analysis of the materials used in the UK's ageing nuclear reactors shows there may be life in them yet. University of Bristol structural integrity lecturer Harry Coules discusses the issues around plant operating extensions.
Abstract In the equation determining the change in the thickness of side walls of thermocasted cylindrical and conical products, it is proposed to replace the experimentally determined value of the cooling coefficient with a calculated one.
A finite element method (FEM)-based simulator with capability of parallel computing is developed for Multiphysics modeling and simulation of resistive random access memory (RRAM) array. The thermal crosstalk effects of a high density vertically integrated RRAM array are investigated. Simulation results show that sever…
In order to develop a process for manufacturing a composite structure of an intermetallic compound foam and a hollow material, the firing and pore form of the Al-Ni precursor in a steel pipe are investigated. When the Al-Ni precursor is foamed in a hollow pipe, if the temperature distribution inside the precursor is u…
The nonlinear characteristics of an electronic device appears a strong effect on the system performance at a high frequency and high power. In this paper, we proposed a new approach to model nonlinear capacitors in the system, and our approach with nonlinear capacitors is validated a very high accuracy.
In this paper, three techniques to obtain capped magnetite nanoparticles were compared. In the formation of magnetite nanoparticles via the co-precipitation route, capping agents were introduced pre-, simultaneously with, or post-addition of the precipitating agent, ammonia. The amino acids L-glutamine and L-glutamic…
NiCuZn spinel ferrite particles were sintered into 50 μm-thick plate and mounted in between IC die and its interposer to explore their suitability as electromagnetic noise suppressor up to 10 GHz. A 50 μm thick Y-Type hexaferrite plate with density of 5.2 g/cm3exhibits the figure-of-merit, Ploss/Pin, as high as 0.27 a…
Abstract Results are presented concerning experimental studies on the properties of carbon-fiber-reinforced plastics made of metallized carbon tapes. As the object of investigation, FibArm and LUP carbon tapes have been used. A magnetron sputtering technique has been used for the deposition of copper coatings onto the…
CPU is the key to achieving optimal performance for any operating system. The highest temperature which a CPU can operate without interruption is 90 °C. Heat sink fans generally provided for removal of heat produced by the processor. However, the situation is different when energy is coupled to the heat sink. The size…
As automation systems become more common, there is growing interest in functional labeling systems using organic and inorganic hybrid materials. Especially, the demand for thermally and chemically stable labeling paper that can be used in a high temperature environment above 300 °C and a strong acid and base atmospher…
