This article summarizes the challenges and some of our preliminary results for our MAS-net (Mobile ActuatorSensor Networks) project. Combining robotics and sensor network technologies, the MAS-net system is designed as a test bed for diffusion system estimation and control. The long-term goal of this research is to estimate and eliminate dangerous plumes, such as air/water pollutions, terrorism...

Particulate matter (PM 2.5 and PM 10 ) ozone (O 3 are the two major air pollutants in China recent years. The fluctuations of , O strongly depend on weather processes anthropogenic emission. These may lead to existence short- long-term memory behaviors pollutants. Hence, here we use autoregressive parameter a first-order process [AR (1)] characterize short-term effects We estimate scaling expon...

Petroleum hydrocarbon is an energy source that drives our modern society and at the same time impacts environment. The consequences of pollution range from microbial diversity distortion to cancer scourge in humans. To reverse these negative trends imposed by contaminated environment, deliberate remediation steps, need be employed, which depend on physical, chemical, biological mechanistic prin...
