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...
Agro-climatic change and european soil suitability: regional modelling at monthly time-steps
model land use evaluation soil water balance crop phenology agro-climate
2008/11/26
This paper describes the development of ACCESS-I (Agro-Climatic Change and European Soil Suitability), a model that will simulate the soil water balance and crop growth, for soil map units within regi...
Impact of microstructure in modelling physical properties of cereal extrudates
microstructure physical properties extrudate cereals extrusion-cooking
2008/11/26
A research was carried out into the extrusion process of corn semolina and oat bran mixtures with single- and twin-screw extrusion-cooking. The effect of an extruder used, of the concentration of oat ...
Finite element modelling of heat transfer in avocados
precooling heat transfer modelling finite element avocado
2008/11/21
A two-dimensional finite element model was developed to predict temperature distribution in individual avocados subjected to air precooling. The proposed model, suitable for axisymmetrical shaped frui...
Ifluence of soil structural parameters on hydraulic functions for soil-water balance modelling
soil strucutre parameters soil hydraulic properties soil-water balance modelling tension infiltrometer Guelph permeameter
2008/11/18
The investigations were conducted to prove the application of different methods for measuring soil hydraulic properties. Estimations of unsaturated hydraulic conductivity with different models were co...
Mass and volume modelling of tangerine (Citrus reticulate) fruit with some physical attributes
tangerine physical attributes mass/volume modelling grading
2008/11/14
There are instances in which it is desirable to determine relationships among fruit physical attributes. For example, fruits are often graded on the basis of size and projected area, but it may be mor...
Wind-caused air transport through greenhouse screens: a physical modelling approach
air exchange porous screen greenhouse wind pressure physical model
2008/11/10
An understanding of the air exchange through screens is needed to optimise climate control strategies in greenhouses. An analysis of the airflow through porous screens due to wind pressure was perform...
