A B S T R A C T The aerosol effects on clouds and precipitation in deep convective cloud systems are investigated using the Weather Research and Forecast (WRF) model with the Morrison two-moment bulk microphysics scheme. Considering positive or negative relationships between the cloud droplet number concentration (N c) and spectral dispersion (o), a suite(More)
Mobile smartphones are increasingly used worldwide and play an essential role in the mobile Internet today for green communications and networks. Smartphones have been used as a cost-effective method to sense and monitor mobile cellular networks, e.g., network coverage, mobile traffics, and Quality-of-Experience of subscribers. In this paper, we propose a(More)
Despite the importance of precipitation and moisture transport over the Tibetan Plateau for glacier mass balance, river runoff and local ecology, changes in these quantities remain highly uncertain and poorly understood. Here we use observational data and model simulations to explore the close relationship between summer rainfall variability over the(More)
In wireless cellular system, due to the convergence of user behavior, there usually exists some typical scenarios which exhibit different traffic patterns, e.g. stadium, campus and central business district (CBD). Accurate traffic scenario recognition and analysis will lead to more efficient resource management and better QoS (quality-of-service) provision.(More)
With the dense deployment of low power node such as Internet of Things (IoT), indoor localization is growing rapidly, has gained a lot of interests in commercial applications. This paper proposes an Iterative Weighted KNN (IW-KNN) indoor localization method based on RSSI (Receive Signal Strength indicator) of the BLE (Bluetooth Low Energy), which has a low(More)
