Frequent itemset mining (FIM) plays an essential role in associations, correlations and many other important data tasks. Unfortunately, as the volume of dataset gets larger day by day, most FIM algorithms literature become ineffective due to either too huge resource requirement or much communication cost. In this paper, we propose a balanced parallel FP-Growth algorithm BPFP, based on PFP [1], which parallelizes MapReduce approach. BPFP adds into load balance feature, improves...
Pure BiFeO3 (BFO) and 3, 5, 7 at. % Mn-substituted BFO (BFMO) films were formed by chemical solution deposition with a crystallization temperature of ∼550 °C. The leakage current density in film was found to be subject space-charge-limited conduction, instead Poole–Frenkel emission. Moreover, the serious transient effect from traps observed, indicating trap states is relatively high film. On contrary, currents BFMO trap-free Ohmic conduction.
Data Locality is one of the critical factors to affect performance. This paper proposes a next-k-node scheduling (NKS) method improve data locality map tasks. The first calculates probabilities each task, and then preferentially schedules with highest probability. It generates low for tasks which satisfy node nodes issue requests, so it can reserve these nodes. We have implemented NKS in hadoop-0.20.2. experiment results shown that reduced 78% processed without locality, 77%of network load...
A nanoscale reconfigurable magnonic crystal is designed using voltage-controlled perpendicular magnetic anisotropy (PMA) in ferromagnetic-dielectric heterostructures. periodic array of gate metallic strips placed on top a MgO/Co structure order to apply electric field and modify the PMA Co. It numerically demonstrated that introduction PMA, which can be realized experimentally via applying voltage, modifies spin-wave propagation leads formation band gaps spectrum. The controlled, i.e., it...
A two-step sintering process has been adopted to produce NiZn ferrite with composition of (NiO)0.35(ZnO)0.57(CuO)0.08(Fe2O3). The densification, microstructure, and magnetic properties the have investigated compared those ferrites produced by traditional final-stage process. It was found that sample a high temperature 1200 °C lower 1100 attained more than 96% theoretical density had uniform microstructure small average grain size. also exhibited good performances in terms permeability...
Ultra-large-area self-assembled monolayers of gold nanoparticles are coated on the intrinsic silicon to boost generation electron–hole pairs upon laser illumination. As a result, larger optical modulation depth terahertz wave can be obtained by monolayer in comparison with bare silicon. service our authors and readers, this journal provides supporting information supplied authors. Such materials peer reviewed may re-organized for online delivery, but not copy-edited or typeset. Technical...
In the present work, Li 0.43 Zn 0.27 Ti 0.13 Fe 2.17 O 4 ferrite, a low temperature sintered gyromagnetic material, was prepared via solid‐state reaction method. A pure spinel phase can be formed with sintering ranging from 880°C to 920°C, which allows them co‐fired silver. The addition of ZnO–Bi 2 3 –SiO ( ZBS ) glass in ferrites contributes significantly grain growth and ferromagnetic properties through (~900°C) process. Results show that (0.125–2.00 wt%) cannot only double saturation...
Magneto-dielectric materials with matched permeability and permittivity are promising candidates as loading to reduce the physical dimensions of low-frequency antennas. In this study, NiCuZn ferrites were prepared by both traditional final-stage sintering process two-step obtain magneto-dielectric materials. It was found that samples sintered tended microstructure dense, homogeneous, small average grain size, which favorable low magnetic dielectric losses. The sample high temperature 950 °C...
There is a wide application prospect in black silicon, especially solar cells and photoelectric detectors. For further optimization of it important to study its optical properties.

The simulated reflectance spectra matches well with measured curve. Also, intensity distribution shows that near 80%...
Interfacial properties play a vital role in spin current injection from the ferromagnetic (FM) layer into nonmagnetic (NM) layer. So far, impedance matching and spin-orbit coupling are two important, well-known factors transport FM/NM heterostructures.

The fabrication and photocatalytic properties of visible-light driven CuInSe2/TiO2 heterojunction films are reported. CuInSe2 nanoparticles (NCs) were synthesized using a solvothermal method then decorated onto self-organized anodic TiO2 nanotube (NT) arrays through an electrophoretic deposition process, forming NC/TiO2 NT hetero-structure film. An increase in time produced increased amount NCs loaded the arrays, expanding light-absorption range NCs/TiO2 NTs film from 400 nm to 700 nm....
TiO2 films consisting of single-crystal anatase nanoparticles with exposed {001} facets were fabricated from anodized nanotube arrays.
