MT-INSAR LANDSLIDE MONITORING WITH THE AID OF HOMOGENEOUS PIXELS FILTER
Goldstein filter Homogeneous pixels filter TerraSAR-X SBAS Landslide monitoring
2018/5/15
SAR interferograms are often contaminated by random noises related to temporal decorrelation, geometrical decorrelation and thermal noises, which makes the fringes obscured and greatly decreases the d...
Moving horizon filter for monotonic trends
Noisy measure the limited state the trend of optimization algorithm mechanical damage the exponential distribution noise
2015/8/11
This paper presents a novel approach for constrained state estimation from noisy measurements. The optimal trending algorithms described in this paper assume that the trended system variables have the...
Biofiltration of Nitrous Oxide Using Cow-Manure Based Compost as Medium Filter
Biofilter Compost Cow-Manure Nitrous Oxide Removal Efficiency
2013/3/11
Nitrous oxide (N2O) gas is a fourth contributor in the greenhouse effect after CO2, CH4, and water vapor. Although its concentration is relatively low, but very difficult to be decomposed in the atmos...

This paper presents an evaluation of the suitability of a mixed absorbent based on peat and carbon-containing ash for treatment of wastewaters, such as wastewater from professional car washes, landfil...
Characteristics of Submicron-sized Aerosol Filtration and Pressure Drop of an Electret Filter Installed in an Air Diffuser in a Residential Apartment Unit
Electret filter Filtration Pressure drop
2016/3/28
We investigated submicron-sized aerosol filtration and the pressure drop of an electret filter called a “Flimmer filter.”
The fibers of the filter are aligned parallel to the direction of the airflow...
The Influences of Diesel Particulate Filter Installation on Air Pollutant Emissions for Used Vehicles
Diesel vehicle Smoke Particulate matter Diesel particulate filter PAHs
2016/3/28
Three kinds of diesel particulate filters (DPFs) were installed on used diesel-powered vehicles to investigate their
influences on air pollutant emissions. The air pollutant emissions were measured b...
