We design a new interconnection network topology and a custom routing algorithm, which targets solving new challenging issues posed by recent advanced studies in the areas of massively parallel computing and large-scale data centers. We follow the design principles of Distributed Shortcut Networks (DSN) [1], which con…
By solid-state magic angle-spinning nuclear magnetic resonance spectroscopy (NMR), differential scanning calorimetry (DSC), and IR spectroscopy, polytetrafluoroethylene (PTFE) samples obtained by low-temperature (T = −196°C) postradiation polymerization of tetrafluoroethylene (C2F4) and C2F4 mixtures with a 3D graphen…
We demonstrate that graphene field effect transistors can operate as both plasmonic and bolometric THz sensors depending on polarization and bias configurations. The plasmonic mechanism of detection is consistent with the overdamped plasma wave response. The bolometric regime is caused by the shift of the Dirac point…
The characteristic of artificial circular dielectric material in microwave engineering is studied. The study encompasses theoretical analysis of artificial circular dielectric, such as anisotropic permittivity characteristics, frequency characteristics and resonance mode in transverse electric mode when the material i…
The effects of substituting a potassium ion for a barium ion in barium phosphate on lattice parameters and proton migration were investigated using density functional theory. A proton inserted into the material preferred to be attached to an oxygen ion near the potassium ion to compensate for the positive charge of th…
Conditions for the existence of a surface polariton at the semiconductor-dielectric interface have been analyzed. With allowance for the gyrotropy and the resonance frequency dispersion of the semiconductor, which manifests itself in an external magnetic field, the dispersion relation, the characteristic frequencies d…
ω- N,N -Dihydroxyethyl aminopropylpolymethylhydrosiloxane (DAPS) a monotelechelic polydimethylsiloxane with a diol-end group, which is used to prepare polyurethane surfactant, was successfully synthesized. The preparation included four steps, which are hydroxyl protection, alkylation, hydrosilylation, and deprotection…
In this study, a new series of optically active poly(amide-imide)/zinc oxide hybrid nanocomposites were fabricated by the sonication-assisted method. The compatibility of the organic and inorganic parts was effectively improved by reducing in aggregation of nanoparticles by surface modification using the coupling agen…
In this study, graphene samples prepared by mechanical exfoliation were examined by Raman spectroscopy. The Au electrical contacts, fabricated using photolithography, allowed the application of a gate voltage between graphene and the Si substrate. In the Raman spectra of the sample, we observed shifts of position, cha…
The switch from 2D filtration to 3D filtration of surface microtopography is described. Important new surface parameters in the metallurgical industry are considered. The use of 3D parameters reveals new aspects of working-roller wear and the development of roughness at the surface of cold-rolled and galvanized auto-i…
The interest in using CNTs as the reinforcement of metal matrix nanocomposites has been growing considerably due to their enhanced properties. In the present work, nickel was reinforced by carbon nanotubes (CNTs) via high energy mechanical milling method. The effects of various amounts of CNTs (5%, 10%, 20% and 30%) a…
The three primary ferroic properties, namely, ferromagnetism, ferroelectricity and ferroelasticity, have been observed in biological systems. The quest for the fourth primary ferroic, namely, ferrotoroidics, along with magnetoelectricity and multiferroic behaviour in biological systems is under way. Control of such bi…
Abstract. Nanocomposite Li4Ti5O12/carbon nanotubes (Li4Ti5O12/CNTs) are facilely synthesized by a sol-gel method. The crystal structure and morphology of the nanocomposite Li4Ti5O12/CNTs are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM), respectively. CNTs play the important role just…
Features associated with short and prolonged growth time in the chemical vapor deposition process of growth of graphene stacks on SiC (0001) substrate are reported. In particular general bimodal (as far as d002 interlayer spacing is concerned) distribution of graphene species across the surface of the samples is obser…
The role of temperature and temporal conditions of ion cleaning is revealed and optimal process and temperature modes of its performance before the formation of the Ti-Al-N-based films with a homological temperature no higher than 0.22T m.f are established. It is determined that, during film deposition, each variable…
Exploit the flux concentration design is good alternative for designing a relatively low cost synchronous motor based on ferrite magnets. The paper discusses the design of the feedback control laws for the stator current and mechanical speed of a synchronous motor in which the magnets are placed transversely along the…
The bufferless deflection routing is recently emerged as a promising approach for improving energy efficiency of on-chip networks. In this on-chip router design, input buffers are removed, and instead deflection (i.e. misrouting) is used to resolve contention among arriving packets. However, to be effective, this conc…
Thermoplastic vulcanizate (TPV) based on natural rubber (NR) and polypropylene (PP) blends were successfully prepared through a dynamic vulcanization process using Brabender Plastograph EC Plus with a rotor speed of 60 rpm at 180°C. Sulfur vulcanization system was used to cure rubber phase in the TPVs. Three grades of…
Swift heavy ion (SHI) irradiation of materials induces variety of functionalities and tenability in advance materials. Recent observations of electrical switching in perovskite oxides have triggered a lot of interest for its potential use as non volatile random access memory (NVRAM). We report on the resistance switch…
We present results of our systematic investigation and comparative analysis of the spectral-kinetic properties of absorption and fluorescence of two series of related planar porphyrins in liquid media at 293 K, in which deviations from the planarity are caused by contact steric interactions of eight peripheral β-pyrro…
