A note on mixed boundary value problems involving triple trigonometrical series

This study was motivated by the two-dimensional hydrodynamic slamming problem of a steep wave hitting a vertical wall. The fundamental problem considers dual impact on the wall at the lower and upper region resembling the impact of a wave at the time of its breaking. The solution method results into a mixedboundary value problem that involves a triplet of trigonometrical series which, to the au...

Fragile watermarking using finite field trigonometrical transforms

Fragile digital watermarking has been applied for authentication and alteration detection in images. Utilizing the cosine and Hartley transforms over finite fields, a new transform domain fragile watermarking scheme is introduced. A watermark is embedded into a host image via a blockwise application of two-dimensional finite field cosine or Hartley transforms. Additionally, the considered finit...

A dictionary’s macrostructure, nomenclature or lemma-sign list is, in simple terms, the inventory of all the headwords in that dictionary. Each of those lemma signs (headwords) is a canonical form, representing an entire paradigm of morphologically-related forms. The use of dictionary citation forms to group related forms is both a space-saving device that stems from the times of the paper dict...

− The Laboratory of Biometrology of PUCRio has been developing magnetic field transducers to be used in biomedical applications. Investigations recently accomplished indicate the possibility of a new research line, which considers the changes in the phase characteristics of Giant Magnetoimpedance (GMI) sensors due to varying low-intensity magnetic fields. In spite of being less explored in the ...
