To identify grain size characteristics of soils, grain size distribution curve is developed. First,sieve analysisis conducted. A variety of sieves with different openings are stacked, with the largest opening sieve on the top and smaller on the lower sections. When a relatively large percent passin...
Grain size distributionCumulative frequency curveStatistical analysisIt is a good method to utilize the grain size distribution curves and cumulative frequency curves of marine or river sediments to estimate the hydrodynamic conditions, transportation processes and sedimentary environment. However, researchers ...
Many models are available to fit the curve of a grain size distribution, GSD. The article lists 61 models and 33 comparative studies of models. Examples explain how to extract stratification data from split-spoon samples and how to verify whether a model respects the internal structure of the ...
Cumulative frequency curves become very gradual and reach the top of the cumulative curve in advance. PLA/1 and Straw/1.5 samples gave broader sediment grain size distribution ranges relative to others types of sand barrier. The peak value is slightly low and slightly in advanced (Fig. 7). ...

grain size analysis; deep leaning; histogram layer; grain size cumulative curve; simulation experiment1. Introduction Sedimentary physical simulation is an important method used in sedimentology, simulating sedimentary processes in natural environments through physical experiments. Sedimentary simulation ...
Microsoft Excel (Microsoft, Redmond, WA, USA)) was used to format data. JMP (JMP®, Version 12.1.0. SAS Institute Inc., Cary, NC, USA) and R (R, Version 3.3.2, R Foundation for Statistical Computing, Vienna, Austria) were used for analysis. Data were tested for normal distribution...
Raw testing data can be exported to XML files which can be imported into Excel The software features both submittal-quality chart reports and textural reports listing raw testing data. Multiple report chart report formats are available for reporting particle size, and Atterberg test results. ...
Full size image Aboveground biomass accumulation during anthesis majorly contributes to grain yield Wide variation (P < 0.05) was observed among 195 lines for biomass accumulation at anthesis, post-anthesis, and at harvest between the two years (Additional file 1: Table S4). The average of ...
