Methods of Continuous Particle Sampling by Aircraft

Developments in Continuous Fine Particle Mass Monitoring: Sample Equilibration and Differential Particle Sampling

Two major advances in real-time monitoring of fine particles were supported under this research. These include reducing the moisture content of the sampled ambient air so that the temperature of the device could be reduced from 50°C to 30°C, and developing an innova­ tive approach to account for the loss of semivolatile materials on the filter surface. The devices have the potential to provide ...

Sampling trace organic compounds in water: a comparison of a continuous active sampler to continuous passive and discrete sampling methods.

A continuous active sampling method was compared to continuous passive and discrete sampling methods for the sampling of trace organic compounds (TOCs) in water. Results from each method are compared and contrasted in order to provide information for future investigators to use while selecting appropriate sampling methods for their research. The continuous low-level aquatic monitoring (CLAM) sa...

Investigation Resistance of Sediment Particle to Erosion in Saraskanchai River by Use of Mathematical Methods

In addition to Erodibility of sediment particles in river increase river sediment load, they are important factors in morphological changes. In the rivers that erodibility is high, trend of morphological changes are intensive that in this case, river is unstable. On the contrary, it will lead stability and low changes of the river. Study area of this research is Saraskanchay that has been locat...

The Effect of Observation Data Sampling Methods on Infiltration Areas by Maximum Entropy Model

Statistical modeling methods are based on multivariate regression methods and require the presence and absence location of data for the construction of the model. In most cases, there is no trustworthy absence data. Therefore, other methods that are based only on the presence of the phenomenon are used. Considering the importance of modeling - saving time and cost and the probable prediction of...
