Multiscale simulations of molecular systems such as proteins, DNAs, and RNAs are implemented using models with different resolutions ranging from a fully atomistic model to coarse-grained molecules, up to a continuum level system descriptions. For such simulations, pairwise force calculation is a serious bottleneck wh…
Four novel three-dimensional lanthanide-thiophenedicarboxylate hybrid compounds, Tb4(C44S6O37) [Tb4(2,5-TDC) [1]; TDC= thiophenedicarboxylate]; space group P-1, a=12.8068(9) ? , b=14.5574(10) ? , c= 19.1276(12) ? , α= 106.660(2)̊, β= 105.621(2)̊, γ= 93.691(2)̊, V= 3251.21(4) ? 3 , Dy4(C46H43O32S6) [Dy4(2,5-TDC) [2]],…
The service induced defects in CRM rolls, due to them being subjected to complex mechanical & thermal stresses in cold rolling of steel strips or coils, if not removed completely during roll grinding, become primarily respo-nsible for roll spalling. The high instances of roll spalling lead to increased specific roll c…
A blue emission powder phosphor , Sr2CeO4 was prepared using solid-state reaction technique. The powder fired at 1100C for 3 hours gave good luminescence yield. The emission peak of this phosphor is at 470 nm. To use this phosphor in a tricolor lamp effectively, studies have been carried out to see the effect of rare…
on 26-28 of October 2010.The event addressed the challenges facing the designers of the next generation aircraft that can be complex and have to operate under strict environmental rules and life-cycle cost and efficiency pressures.The conference attracted contributions that covered current research and thinking about…
Monoklonove protilatky predstavuju v sucasnosti jeden z najvyssich stupňov farmakologickeho vývoja. Oproti minulým nazorom sa zda, že oblasťou ich uplatnenia nebude iba okruh autoimunitných ochoreni, ale ich skutocne klinicke použitie bude jednoznacne sirsie vratane napr. exponovanej nadorovej problematiky. Prehľadový…
In a given review, the description of the energy spectrum of electrons and the frequency spectrum of atomic vibrations of the crystal lattice are considered. The basic methods for investigation of influence of the anharmonicity effects on the physical properties of materials and a frequency spectrum of vibrations of t…
Vasos de pressao sao equipamentos essenciais para a industria de processo. Eles podem atuar desde o armazenamento como tambem no processamento de fluidos gasosos e liquidos. Sao equipamentos que possuem como requisito principal suportar pressoes elevadas. E esse mesmo requisito que preocupa a seguranca, pois falhas du…
Since plastic deformation of polycrystal sheet metal is greatly affected by its initial and plastic deformed textures, multi-scale finite element (FE) analysis based on homogenization with considering micro-polycrystal morphology is required [1]. We formulated a new crystal plasticity constitutive equation to introduc…
Electronically doped metal oxide nanocrystals, such as indium tin oxide (ITO) and aluminum-doped zinc oxide (AZO) exhibit surface plasmon absorption in the near IR (NIR). In addn., chem. strategies have been developed for achieving conducting networks of nanocrystals that were initially passivated by insulating hydroc…
Along the last years, the practical use of active filters to mitigate harmonics has been extended in electric power systems. Different configurations of series active filters versus shunt active filters have been proposed, among them, hybrid topologies which combine active and passive filters. Nevertheless, there is n…
This report was produced within the framework of the RAAK PRP project ‘Veiligheid op de werkvloer’. Personal protective equipment (PPE) is used on a daily basis by millions of people all over the EU, voluntarily or as a result of EU legislation. In this report we deal specifically with the textile/garment aspects of P…
With the advent of nanotechnology the synthesis of nanostructured materials and their useful applications have become increasingly prominent. Nanostructuring can enhance the performance of functional materials and provides them with unique properties. Exceptional qualities of nanostructured materials compared to the b…
This scientific opinion of EFSA deals with the risk assessment of the substance (butyl acrylate, butyl methacrylate, methyl methacrylate) copolymer, CAS No 25322-99-0, REF. No. 40619 and FCM substance No 865 for which the CEF Panel concluded that the intended use in rigid PVC at a maximum level of 1% w/w and in PLA at…
This paper presents a cascaded multilevel Voltage Source Inverter (VSI) based three-phase shunt Active Power Filter (APF). The active filter is applied for power quality enhancement in the distribution grid in terms of harmonic compensation. The compensation method is proposed by sinusoidal extraction controller, whic…
The essay introduces a high speed detection system for multiple-spindle chemical fabrics viscose filament. It utilizes the special cutter to clamp the bunch of viscose filaments, and uses the specialized shredder to produce the viscose filament slice. We design and produce the hemispherical controlled luminous LED lig…

For its unique electronic characteristics [1,2], graphene has been a material of great interest for scientists since its discovery. While its incredibly high mobility is attractive for high frequency field effect transistor realizations [3], the zero bandgap energy spectrum gives a modest transistor reliability for di…
Computational electromagnetics has become a real cornerstone in the design of microwave and millimeter wave components and systems. One of the major computational techniques used in these designs is to solve integral equations with the Method of Moments (MoM). Traditionally, MoM has been used extensively for antennas,…
In this paper, a time-frequency filter is designed, which can detect the frequency, amplitude and phase of any order harmonics and interharmonics in signal by means of time domain convolution. The theory analysis are carried to this method and the calculate formula are concluded, the spectral leakage and the barrier d…
