Community detection is an important methodology for understanding the intrinsic structure and function of complex networks. Because overlapping community one characteristics real‐world networks should be considered detection, in this article, we propose algorithm, called link‐based label propagation algorithm (LinkLPA), to detect communities. link partition conceptually natural problem LinkLPA first transforms node into employs a new with preference on links instead nodes communities due...
This study investigated direct fluorescence generation from a nematic liquid crystal (NLC) NJU-LDn-4 under femtosecond laser excitation. The absorption, transmittance, excitation, and emission spectra of the NLC were assessed. relationship between pump power intensity was analyzed, revealing quadratic increase indicating that two-photon absorption (2PA) is primary mechanism. LC microstructure designed using photoalignment technology, allowing generated to reflect corresponding structure....
A novel modeling method based on the parametric domain decomposition is proposed for B-spline surfaces. This combines advantages of conventional and Bezier Moreover, a fast algorithm new presented to locate stationary points, including inner boundary physical optics (PO) integrals from targets modeled with double-quadratic In this algorithm, locating problem reduced numerical or analytical solution. No approximation involved in algorithm. The phase by means employed evaluate PO integrals....
This paper presents a new three-dimensional (3D) imaging method for detecting the spatial structure of complex inner cavity based on positron annihilation and γ-photon detection. first marks carrier solution by certain radionuclide injects it into where positrons are generated. Subsequently, γ-photons released from annihilation, detector ring is used recording γ-photons. Finally, two-dimensional (2D) image slices constructed ordered-subset expectation maximization scheme 2D merged to 3D...
The rapid development of wireless communication comes at the cost dramatically increasing energy consumption, which makes optimisation efficiency (EE) extremely important. In this study, authors focus on maximising EE large‐scale multiple‐input–multiple‐output system by optimising transmit power and number selected base station antennas. First, problem, i.e. finding optimal EE‐based values each parameter, when other one is fixed, investigated. Then, problem jointly considering these two...
In this paper, we propose a general and efficient lattice Boltzmann (LB) model for solving the nonlinear thermistor equations, where diffusion Poisson equations are solved by two LB equations. Through Chapman–Enskog analysis, can be recovered correctly from present model. We then test through some numerical simulations, find that results in good agreement with analytical solutions. Additionally, also show has second-order convergence rate space.
A fast shadowing algorithm based on Levin method is proposed for physical optics (PO) integrals from the targets modeled with a B-spline surface. The CPU time of independent incident frequency. In algorithm, scatterer assumed to be fully illuminated by plane wave, and computation performed only endpoints subintegrals, which are obtained subdividing PO according location critical points. To compute these points, including stationary resonant points integrals, we also propose localization...
By means of the microstructure observation and creep properties measurement, an investigation has been made into influence salt quenching temperatures on property FGH95 superalloy. The results shown that, after full heat treatment, a high volume g￠ phase some granular carbide dispersedly precipitate in matrix. Thereinto, as molten temperature decreases from 650℃to520℃, size fine alloy decrease gradually amount carbides increase alloy. And quenched at520℃possesses better resistance due to...
The imaging characteristics of large elliptical orbit synthetic aperture radar (SAR) are different from those conventional circular SAR because its eccentricity. For the first time, and algorithms studied. Firstly, analyzed, such as spatial geometry, ground beam footprint, time-varying satellite velocity, Doppler characteristics, time azimuth resolution. On this basis, an algorithm is proposed, echo signals at orbital positions imaged using back projection (BP) algorithm. simulation results...
Abstract The creep fracture mechanism of FGH95 superalloy has been investigated by means microstructure observation and behaviour measurement. Results show that, after solution treatment at 1150°C, the coarser γ′ precipitates distribute in wider regions previous particle boundaries. As temperature increases to 1165°C, grains grow alloy carbide films precipitate along grain When is treated 1160°C, phase boundary fully dissolved, granular carbides boundaries, which may effectively restrain...
