Statistics of electric vehicle travel time in a certain city
No full text<p>This dataset contains data on the charging time of electric vehicles for a typical month in a certain city. The types of electric vehicles include: buses, private passenger cars, ride hailing vehicles, logistics vehicles, and rental passenger cars. The activity area is divided into: office area, industrial area, residential area, and commercial area. The dataset takes one hour as the statistical cycle to calculate the charging frequency of electric vehicles of various types and regions during a certain period of time.</p><p>This dataset is selected from the electric vehicle charging station status statistical dataset provided by Henan Power Grid. When organizing this dataset, unnecessary status data was removed and October was taken as a typical month, and the charging data of electric vehicles in October was extracted separately.</p>
Effect of two asymmetries on current of a Brownian particle
No full textA Brownian particle in an asymmetric periodic potential and subjected to an asymmetric
dichotomous noise was investigated. In the frame of Fokker-Planck equation, exact
expression of current of the system was derived. By means of numerical calculations, the
results indicate that: (i) as the symmetry of either potential or noise is broken, a
steady current will form; (ii) as the two symmetries are broken simultaneously, the
current does not always appear, dependent on values of symmetric parameters of the
potential and the noise; (iii) the current exhibits non-monotonic behavior as a function
of symmetric parameter of the potential, while monotonic behavior as a function of
symmetric parameter of the noise; (iv) in the case the potential symmetry is not broken
seriously, the current is greatly influenced on by the noise symmetric parameter; (v)
absolute values of the current as a function of height of potential barrier first increase
then approach to saturation as the spatial potential is symmetric, while varies
monotonically as the dichotomous noise is symmetric. In addition, the planes of the two
symmetric parameters, which determine directions of the current, are drawn
