The number of households and businesses using HFC cable networks for Internet access is rapidly approaching 40 million in the United States. The cable industry has standardized on a single MAC and physical layer standard, the Data Over Cable System Interface Specification (DOCSIS). The emerging IEEE 802.16 broadband wireless access MAC protocol is based on DOCSIS. We have implemented a simulati...

There is growing interest for the installation of green stormwater infrastructure (GSI) to improve control, increase infiltration stormwater, and receiving water body quality. Planning level tools are needed inform municipal scale decisions on type extent GSI apply. Here, a modified methodology developed EPA Storm Water Management Model (SWMM) create SWMM Low Impact Technology Evaluation (SWWM-...

Waterlogging simulation is a key technology for solving urban waterlogging problems. The current modeling process relatively complex and requires high basic data, which not conducive to rapid popularization. In this study, we evaluated the correlation between rainfall water using following factors: terrain, evaporation, infiltration, pipe drainage capacity, river flood level. By quantifying inf...

In this paper, a planning analysis of implementing low impact development (LID) type of stormwater best management practices (BMPs) for urban runoff control is presented. The Beijing Olympic Village (BOV) residential area in China was used as a case study. The original BOV stormwater system incorporated some LID BMPs such as porous pavements, green roofs and rainwater cisterns. After the 2008 O...
