Spatio-temporal Nitrogen fertilizer response in maize: Field study and modeling approach
(American Society of Agronomy, 2016-09)
Maize (Zea mays L.) yield and its response to nitrogen (N) are affected by the spatial variability of the interaction between weather, management, and soil properties. The objectives of this study were (i) to evaluate the ...
Modeling field load tests in lateritic unsaturated soil
(Crc Press-taylor &francis Group, 2015)
Dynamical mean field theory of an effective three-band model for NaxCoO2
(American Physical Society, 2009-01)
We derive an effective Hamiltonian for highly correlated t2g states centered at the Co sites of NaxCoO2. The essential ingredients of the model are an O mediated hopping, a trigonal crystal-field splitting, and on-site ...
Continuum approach to computational multi-scale modeling of fracture
(Trans Tech Publications, 2015-01)
This paper presents a FE2 multi-scale framework for numerical modeling of the structural failure of heterogeneous quasi-brittle materials. The model is assessed by application to cementitious materials. Using the Continuum ...
Strong magnetic fields in nonlocal chiral quark models
(American Physical Society, 2017-12)
We study the behavior of strongly interacting matter under a uniform intense external magnetic field in the context of nonlocal extensions of the Polyakov-Nambu-Jona-Lasinio model. A detailed description of the formalism ...
On the energy crisis in noncommutative CP(1) model
(Elsevier Science, 2010-08)
We study the CP(1) system in (2 + 1)-dimensional noncommutative space with and without Chern– Simons term. Using the Seiberg–Witten map we convert the noncommutative CP(1) system to an action written in terms of the ...
Iterated Conditional Modes to Solve Simultaneous Localization and Mapping in Markov Random Fields Context
This paper models the complex simultaneous localization and mapping (SLAM) problem through a very flexible Markov random field and then solves it by using the iterated conditional modes algorithm. Markovian models allow ...
