The paper presents a hysteresis-controlled buck converter with active pseudo-current and frequency-locked techniques. The hysteresis-controlled method accelerates the transient response in the load variation. The proposed buck converter uses phase-frequency locked technique to solve the variable switching frequency and electromagnetic disturbance problems. Therefore, the frequency-locked circuit is used to fix the switching frequency. The stable output voltage is important, when the input or output voltage is changed.

In this letters, a new measure called communication robustness (CR) for network robustness is presented from the standpoint of network structure, which not only confirms the dominant effect of the giant connected component on the network robustness, but captures the local communicability of all small connected components. Furthermore, we prove that the optimal edge-adding problem to improve the CR is NP-hard. To cope with the NP-hard problem, we propose a simulated annealing algorithm in terms of the proposed CR measure.

The data conclude two parts, i.e. shapefiles and excel files. The latter collected POI information of Beijing about the geographical coordinates, rating and other related description fields up to Aug 2017.
