A unified formulation as well as numerical approach is presented both for the twoand three-dimensional incremental quasi-static problems with unilateral frictional contact. Under the assumptions of small rotations and small strains, a Second-Order Cone Linear Complementarity Problem (SOCLCP) is formulated, which consists of complementarity conditions defined by the bilinear functions and the se...

We present an efficient modal method to calculate the two-dimensional Green’s function for electromagnetics in curvilinear coordinates. For this purpose the coordinate transformation based differential method, introduced for the numerical analysis of surface-relief gratings, is directly used with perfectly matched layers (PMLs). The covariant formalism Maxwell’s equations, very convenient for t...

In this paper the authors derive a higher-order shear deformation theory for modelling functionally graded plates accounting for extensibility in the thickness direction. The explicit governing equations and boundary conditions are obtained using the principle of virtual displacements under Carrera’s Unified Formulation and then interpolated by collocation with radial basis functions. The effic...

A unified formulation and a numerical approach are presented for twoand three-dimensional incremental quasi-static problems with unilateral frictional contact. Under the assumptions of small rotations and small strains, a Second-Order Cone Linear Complementarity Problem (SOCLCP) is formulated, which consists of complementarity conditions defined by bilinear functions and second-order cone const...

The Noether theorem connecting symmetries and conservation laws can be applied directly in a Hamiltonian framework without using any intermediate Lagrangian formulation. This requires a careful discussion about the invariance of the boundary conditions under a canonical transformation and this paper proposes to address this issue. Then, the unified treatment of Hamiltonian systems offered by No...

We propose a new unified approach to deal with two formulations of image distortion and a method for estimating the distortion parameters by using the both formulation; So far either of the two formulations has been developed separately. The proposed method is based on image registration and consists of nonlinear optimization to estimate parameters including view change and radial distortion. E...

This paper compares a number of recently proposed models for computing context sensitive word similarity. We clarify the connections between these models, simplify their formulation and evaluate them in a unified setting. We show that the models are essentially equivalent if syntactic information is ignored, and that the substantial performance differences previously reported disappear to a lar...

In this paper we present a layerwise finite element model for the analysis of sandwich laminated plates with a viscoelastic core and laminated anisotropic face layers. The stiffness and mass matrices of the element are obtained by the Carrera’s Unified formulation (CUF). The dynamic problem is solved in the frequency domain with viscoelastic frequency-dependent material properties for the core....

In Brazil, the right to health was established in 1988 Federal Constitution as a right for all citizens that should be provided by State through social and economic policies. This was the basis for the formulation and implementation of the Unified Health System (SUS), a public system which considered the universality of access to health services in all levels, the integrality of care, the equal...

A unified architecture for radix-2 decimation-in-time fast Fourier transform and inverse discrete cosine transform of type II is presented based on constant geometry formulation of the algorithms. The parallelism of the architecture can be specified to meet various throughput and area requirements. The type and size of the transform in the architecture can be configured in run-time. In addition...
