1. Radio-Wave Propagation Model for UHF Band in Different Climatic Conditions with Dyadic Green’s Function
AbstractThis article proposes a deterministic radio propagation model using dyadic Green's function to predict the value of the electric field. Dyadic is offered as an efficient mathematical tool which has symbolic simplicity and robustness, as well as taking account of the anisotropy of the medium. The proposed model is an important contribution for the UHF

2. Modelagem estatística de extremos espaciais com base em processos max-stable aplicados a dados meteorológicos no estado do Paraná / Statistical modelling of spatial extremes based on max-stable processes applied to environmental data in the Parana State
The most mathematical models developed for rare events are based on probabilistic models for extremes. Although the tools for statistical modeling of univariate and multivariate extremes are well-developed, the extension of these tools to model spatial extremes data is currently a very active area of research. Modeling of maximum values under the spatial dom

3. Simulação numérica para difusão anisotrópica / Numerical simulation to anisotropic diffusion
The present work build a computational model using the finite volumes method for unstructured meshes, with the purpose of calculating the hydraulic load in a porous medium, considering it material non - homogeneous and anisotropic. The Anisotropy is a characteristic of many materials found in the nature and it depends on the property studied in this material

4. Representação Matemática do Comportamento Mecânico Cíclico de Solos Saturados e não Saturados / Mathematical Representation of the Cyclic Mechanical Behaviour of Saturated and Unsaturated Soils
Granular materials, such as soils, exhibit a relatively complex mechanical behaviour. Usually, the mechanical behaviour of soils is studied with the aid of the Continuum Mechanics. Materials under cyclic loadings exhibit a dierent mechanical behaviour, with respect to monotonic loadings. The mathematical theory of elastoplasticity has been employed to the nu
