Examining the Contact Filter Paper Method in the Low Suction Range [PDF]
Geotechnical Testing Journal, 2020 Abstract The filter paper method for measuring suction is standardized in ASTM D5298-16, Standard Test Method for the Measurement of Soil Potential (Suction) Using Filter Paper. The contact filter paper is usually calibrated using a pressure plate apparatus from 10 to 1,500 kPa. The filter paper calibration curve is commonly plotted on a

Filter Paper Method for the Determination of the Soil Water Retention Curve [PDF]
Revista Brasileira de Ciência do Solo, 2015 High cost and long time required to determine a retention curve by the conventional methods of the Richards Chamber and Haines Funnel limit its use; therefore, alternative methods to facilitate this routine are needed.

Characteristics of Soil Suction with Filter Paper Test Method [PDF]
International Journal on Advanced Science, Engineering and Information Technology, 2018 Soil suction is the ability of the soil to absorb water. Type of soil in this research was peat soil and clay soil. The soil samples had been used were taken from Dusun III Banyu Urip, Banyuasin Regency, South Sumatera Province. Laboratory testing with Filter Paper test method. The filter paper used is Whatman Filter Paper No.42.

Medical image enhancement using threshold decomposition driven adaptive morphological filter [PDF]
, 2008 One of the most common degradations in medical images is their poor contrast quality. This suggests the use of contrast enhancement methods as an attempt to modify the intensity distribution of the image.

Fitting models for soil-water characteristic curve of total and matrix suctions of Yili loess
Yantu gongcheng xuebao, 2019 The Yili loess of Xinjiang is characterized by strong collapsibility and high soluble salt content. For describing the suction parameters in the stress state of the unsaturated soils, both the total and matrix suctions should be taken into account ...

Trend Extraction From Time Series With Structural Breaks and Missing Observations [PDF]
, 2008 Trend extraction from time series is often performed by using the filter proposed by Leser (1961), also known as the Hodrick-Prescott filter. Practical problems arise, however, if the time series contains structural breaks (as produced by German ...

Reducing the Excess Variability of the Hodrick-Prescott Filter by Flexible Penalization [PDF]
, 2014 The Hodrick-Prescott filter is the probably most popular tool for trend estimation in economics. Compared to other frequently used methods like the Baxter-King filter it allows to estimate the trend for the most recent periods of a time series.
