The losses caused by natural disasters are increasing, especially in 21st century, the security and the losses increased. Responding natural disasters and reducing losses become an urgent task which facing all of humanity. The paper will propose an allocation method of relief materials for pre-disasters and a shortest-time and potential-considered scheduling model for post-disasters. The allocation...
China is among the countries that have most intense seismic activity and serious earthquake disasters. In order to provide a scientific basis for China Earthquake Planning and construction of mitigation structures, this paper focuses on China earthquake disaster risk assessment and relief materials allocation of the Central Reserve System (CRS) based on the result. Taking into account of four factors...
Based on introduction of image identification, the method of non-linear grid conversion is used to convert the image coordinates into road plan coordinates. Vehicle speed and vehicle distance are adopted to judge free-driving, car-following and lane-changing state of vehicle behavior. According to the body's endurance for acceleration, driving risk is divided into seven levels. Critical acceleration...
Hydraulic accumulator type braking energy regeneration system have the advantages of high power density, low cost and reliable property, which is suitable for the traditional engine driving bus. The variable displacement hydraulic pump/motor is used the braking energy recovery system as regeneration conversion device, its structure parameters affected braking energy recovery rate and regeneration...
Millions of residential users are widely served by cable or DSL connections with modest upload bandwidth and relatively high download bandwidth. For the increasingly important and demanding P2P applications such as VoIP, BitTorrent, and Internet streaming, stable or high upload bandwidth is required. Inadequate upload bandwidth degrades the performance of these applications among residential users...
