Run duration effects on the hydrodynamic properties of a loam soil estimated by steady-state infiltration methods

2020

Steady-state methods for the analysis of single-ring infiltration data are commonly applied. However, the duration of an infiltrometer experiment is often established quite subjectively based on the assumption that in general infiltration stabilizes rather quickly in the field. For a loam soil, the effect of the duration of a beerkan run on sorptivity, S, and saturated hydraulic conductivity, Ks, was tested by using the BEST (Beerkan Estimation of Soil Transfer parameters)-steady method and SSBI (Steady version of the Simplified method based on a Beerkan Infiltration run) method for data analysis. The standard experiment, based on a total of 15 water volumes each establishing an initial pon…

Estimation of salivary cortisol among subjects undergoing dental extraction

2017

Background Dental procedures can be stressful and studies have shown that salivary cortisol is elevated during such procedures. Our study aimed to evaluate saliva cortisol levels among the subjects who underwent dental extractions and to compare it with that of the controls. The secondary objective of the study was to evaluate any correlation between salivary cortisol and hemodynamic parameters. Material and Methods We conducted this clinical study among subjects, who were indicated for dental extraction. Saliva samples from the subjects in the study group were collected before and after (10 mins) the dental extraction. Hemodynamic parameters like heart rate, systolic (SBP) and diastolic bl…

Päätöspuiden käyttö koneoppimisessa

2017

Päätöspuihin perustuvia menetelmiä ollaan käytetty laajasti koneoppimisen eri tehtävissä. Tämä tutkielma kokoaa tietoa siitä miten ja mihin näitä menetelmiä ollaan käytetty. Käydään läpi yksittäisen päätöspuun luominen datasta ja tämän pohjalta tutustutaan kokoonpanomenetelmiin, joissa kootaan useita päätöspuita. Lopulta tutustutaan vielä joihinkin esiteltyjen menetelmien sovelluksiin. Methods based on decision trees have been utilized widely in different tasks of machine learning. This study compiles information on how and for what purposes have these methods been used. Construction of a decision tree based on data is explained and with that as a basis ensemble methods, which comprise many…

Darba procesa izveide platformā Microsoft SharePoint

2015

Microsoft SharePoint ir saistīts ar lieliem dokumentu apjomiem un dažādu mijiedarbību ar tiem. Lai padarītu darbu ar datiem vieglāku, SharePoint ļauj lietotajiem izveidot darbplūsmas SharePoint Designer programmatūrā. Tomēr, lietotājs var velēties izveidot darbplūsmu, kura nolasa vērtības no PDF formas laukiem. SharePoint Designer ne piedāvā darbplūsmas darbības kuras ir spējīgas to izdarīt.

Comparing two methods of analysis of single-ring infiltrometer data for a sandy – loam soil

2009

The single-ring pressure i n filtrometer (PI) with the steady-state Two-Ponding-Depth (TPD) applic ation method were developed to simulta neously determine the saturated soil hydraulic conductivity, K , and the α ⁎ -parameter in the fi eld. Methods of analysis of transient PI data are also available but they have received little testing so far. The transient WU method and the TPD method were compared for a sandy-loam soil. A linearization technique o f the in filtration curve yielded more reliable K fs fs and α ⁎ results (i.e., falling within expected ranges) than a non-linear optimization technique. The WU method gave both positive and reasonable K and α ⁎ values for all infi ltration tests. U…

Improvement of BEST (Beerkan Estimation of Soil Transfer parameters) method for soil hydraulic characterization

Interpreting and modeling soil hydrological processes require the determination of the soil hydraulic characteristic curves, i.e. the relationships between volumetric soil water content, pressure head, and hydraulic conductivity. Using traditional methods to determine these properties is expensive and time consuming. Haverkamp et al. (1996) pioneered a specific method for soil hydraulic characterization known as the “Beerkan method”. An improved version of this methodology, called the Beerkan Estimation of Soil Transfer parameters (BEST) procedure, was developed by Lassabatère et al. (2006) to simplify soil hydraulic characterization. BEST considers certain analytic formulae for hydraulic c…
