Investigações sobre um esquema numérico desacoplado para modelos de circulação
The numerical modelation by the means of finite elements can represent the frontiers of an irregular water body more eficiently than those models employing finit differences. However, finit differences models are usually solved through highly efficient algorithims, such as the ADI (Alternate …

Instabilidade de estruturas metálicas planas compostas de perfis de chapa dobrada
… is analyzed by means of a geometric nonlinear finit element model which takes also into account an additional nonlinearity due to local "U" section buckling effect. The solution of the nonlinear problem is obtained through a hibrid numerical scheme: incremental/iterative (tangent method) …

Electrical and magnetic properties of organic semiconductors: Electrical conductivity and electron spin resonance studies of semiconducting, organic, charge transfer salts.
… the trapping of excitons on an extended formula finit (TCNQ2 )n. In Chapter IV the temperature dependent magnetic susceptibilities are discussed in terms of Heisenberg antiferromagnetism and Pauli paramagnetism. In Chapter V temperature dependent behaviour of electrical conductivity is discussed …

Thermal Overload Capabilities of an Electric Motor and Inverter Unit Through Modeling Validated by Testing
… and finalize the design. A lumped capacitance finite-difference model was developed to simulate the entire motor inverter assembly. The individual components of the thermal model were tested and the data was used to calibrate and validate the thermal model. Using the model, the thermal overload …

Modeling of Bio-inspired Jellyfish Vehicle for Energy Efficient Propulsion
… We modeled these muscle arrangements through finite element modeling (FEM) to determine their deformation and stroke characteristics and their overall role in bell contraction. We found that location and arrangement of coronal muscle rings plays an important role in determining their efficient …
