Wind environment research in the populated urban area is an important topic on wind potential evaluation as well as wind comfort analysis. This study took measurement of 57 crossroad spots in the campus in North China University of Technology in Beijing. The data of wind speed and direction were...

The shared bicycles had become an important choice for Beijing citizens to travel "the last kilometer" on a daily basis. By replacing buses and cars, sharing bicycles can reduce urban carbon emissions, and only occupy a small area of parking space, thus improving urban land use efficiency. A...

An expanded Bethe–Peierls approximation is used to study the magnetic properties of the magnetic superlattice, which consists of a mixed spin-12 and spin-1 (with a single-ion anisotropy D) alternate ferromagnetic monolayers with antiferromagntic coupling at the interlayers. By using the...

We numerically investigate how to enhance synchronizability of coupled identical oscillators in complex networks with research focus on the roles of the high level of clustering for a given heterogeneity in the degree distribution. By using the edge-exchange method with the fixed degree...

The thermally driven spin transport through mesoscopic ferromagnetic semimetal-normal metal junctions is investigated. A pure spin current can be enforced by the spin-polarised semimetal band structure and the spin current increases with increasing either the temperature bias or the equilibrium...

Rounding of data is common in practice. The problem of estimating the underlying density function based on data with rounding errors is addressed. A parametric maximum likelihood estimator and a nonparametric bootstrap kernel density estimator are proposed. Simulations indicate that the maximum...
