The Conservatorship Model: A Modification

Modification of the GRAMI Model for Cotton

duction. The model was developed and verified using field data from irrigated commercial cotton fields in the A new version of the GRAMI crop model capable of being caliTexas High Plains, USA. The model was validated using brated within season was developed and tested for cotton (Gossypium field data from independent sites in this region, and its hirsutum L.) production in semiarid regions. The...

Combining Prototypes: A Selective Modification Model

We propose a model that accounts for how people construct prototypes for composite concepts out of prototypes for simple concepts. The first component of the model is a prototype representation for simple, noun concepts, such as fruit, which specifies: (1) the relevant attributes of the concepts, (2) the possiblevalues of each attribute, (3) the salience of each value, and (4) the diognosticity...

Adaptive Control with Reference Model Modification

The asymptotic behavior of adaptive systems has been a well researched topic during the last couple of decades, and it is well known that asymptotic tracking can be achieved using the Lyapunov redesign method. However, the transient behavior of the input and output signals can be very oscillatory with significant excursions [1]. There has been a great deal of effort to modify the control archit...

Modification of a maize simulation model under different water, nitrogen and salinity levels

Irrigation, salinity and nitrogen (N) are the three major limiting environmental factors inmaize yield potentials especially in arid and semi-arid regions. An integrated water and N MaizeSimulation Model (MSM) was modified for salinity conditions using 2009-2010 fieldexperiments data in southwest of Iran. Irrigation levels were: I1=1.0ETc+0.25ETc as normalleaching amount, I2=0.75I1 and I3=0.5I1...
