A smoothed finite element method (SFEM) is presented to analyze linear and geo- metrically nonlinearproblems of plates shells using bilinear quadrilateral elements. The formu- lationis based on thefirst order shear deformation theory. In the present SFEM, elements are fur- therdividedintosmoothingcells toperform strain smoothingoperation,andthestrainenergy ineach smoothing cell expressed as an explicit form strain. effect number divisionsofsmoothingcellsinelements isinvesti- gatedindetail....
Traditional parallel algorithms for mining frequent itemsets aim to balance load by equally partitioning data among a group of computing nodes. We start this study discovering serious performance problem the existing Frequent Itemset Mining algorithms. Given large dataset, strategies in solutions suffer high communication and overhead induced redundant transactions transmitted address developing approach called FiDoop-DP using MapReduce programming model. The overarching goal is boost on...
Classification is valuable and necessary in spectral analysis, especially for data-driven mining. Along with the rapid development of surveys, a variety classification techniques have been successfully applied to astronomical data processing. However, it difficult select an appropriate method practical scenarios due different algorithmic ideas characteristics. Here, we present second work mining series - review techniques. This also consists three parts: systematic overview current...
ABSTRACT Clustering is an effective tool for astronomical spectral analysis, to mine clustering patterns among data. With the implementation of large sky surveys, many methods have been applied tackle spectroscopic and photometric data effectively automatically. Meanwhile, performance under different characteristics varies greatly. aim summarizing algorithms laying foundation further research, this work gives a review spectra in three parts. First, are investigated analysed theoretically,...
Large classes of materials systems in physics and engineering are governed by magnetic electrostatic interactions. Continuum or mesoscale descriptions such can be cast terms integral equations, whose direct computational evaluation requires O(N^2) operations, where N is the number unknowns. Such a scaling, which arises from many-body nature relevant Green's function, has precluded wide-spread adoption methods for solution large-scale scientific problems. In this work, parallel approach...
An efficient parallel Stokes' solver has been developed for complete description of hydrodynamic interactions between Brownian particles in bulk and confined geometries. A Langevin the particle dynamics is adopted, where long-range are included using a Green's function formalism. scalable computational approach presented, general geometry Stokeslet calculated following matrix-free algorithm Ewald-like method. Our employs highly iterative finite-element accurate treatment arbitrary...
The parametric resonant behavior of ions inside a linear rf ion trap is studied both theoretically and experimentally. Theoretically, the motion an ideal described by approximating trapping field as harmonic pseudopotential with being excited additional quadrupolar ac voltage. resulting damped Mathieu equation regions instability are predicted investigating solutions. Experimentally, excitation ${\mathrm{Mg}}^{+}$ observed subjecting cloud trapped to field. various resonances detected...

Objective: To accurately estimate the health burden and corresponding economic loss attributed to PM(2.5) pollution in Beijing-Tianjin-Hebei (BTH) area China 2015. Method: By using satellite-retrieved concentration data population provided by NASA (the spatial resolution was 1 km×1 km), this study estimated excess mortality long-term PM(2).5 exposure BTH 2015 based on Global Exposure Mortality Model (GEMM). Besides, Value of Statistic Life (VSL) method used evaluate loss. Result: In area,...
Interfacial energy plays an important role in equilibrium morphologies of nanosized microstructures solid materials due to the high interface-to-volume ratio, and can no longer be neglected as it does conventional mechanics analysis. The present work develops effective numerical approach by means a hybrid smoothed extended finite element/level set method model nanoscale inhomogeneities with interfacial effect, which element mesh completely independent interface geometry. Gurtin-Murdoch...
