Modelling infiltration and geostatistical analysis of spatial variability of sorptivity and transmissivity in a flood spreading area
Philip’s two-term model SCS model variogram
2014/10/23
Knowledge of infiltration characteristics is useful in hydrological studies of agricultural soils. Soil hydraulic parameters such as steady infiltration rate, sorptivity, and transmissivity can exhibi...

Osmotic dehydration recurrent artificial neural network mango water loss full factorial
2010/11/15
Osmotic dehydration process was investigated in this paper. Mango slices samples were
osmotically dehydrated in different hypertonic solutions of glucose and sucrose at three different temperatures (...
TRENDS IN RESEARCH ON THE POSSIBLE EFFECTS OF CLIMATE CHANGE CONCERNING AQUATIC ECOSYSTEMS WITH SPECIAL EMPHASIS ON THE MODELLING APPROACH
ecological modelling model system community ecology global warming seasonal dynamics
2010/3/26
Knowledge on the expected effects of climate change on aquatic ecosystems is defined by three
ways. On the one hand, long-term observation in the field serves as a basis for the possible changes; on ...
Modelling the mass of kiwi fruit by geometrical attributes
kiwi fruit mass models dimensions physical properties geometrical attributes
2008/12/2
The determination of mathematical models for predicting the mass of kiwi fruits from their dimensions and projected areas was done. The research was conducted on 200 observations of two Iranian variet...
Modelling infiltration rate in conditioned soil: comparisonsand modifications
infiltration conditioned soils models
2008/11/26
Prediction of the influence of waste application on agricultural land and on the dynamics of infiltration is crucial for the optimum management of soil water as well as contaminants from runoffs. Thr...
Modelling the effects of repeated wheel loads on soil profiles
compaction wheel loads soil strength finite element modelling
2008/11/26
Compaction of soil caused by increasing mechanical loads and repeated wheeling may result in reduced soil productivity. The physical response of soils to such loading is analysed with a non-linear fin...
