Aniline (ANI) and 2-aminoterephthalic acid (2ATA) copolymers, with different compositions, were prepared by
chemical oxidative polymerization varying the feed ratio. The new materials have been characterized by techniques such
as XPS, FTIR, Raman spectroscopies and thermal analysis. It has been…

The redox process undergone by the electrochemically synthesized poly(2,2-dithiodianiline), poly(DTDA), has been examined in
acetonitrile-water mixtures by electrochemical and spectroscopic techniques. The spectroscopic properties of this material are equivalent to those exhibited by the chemically synthesized one. The polymeric structure…

Two styrene–bTwo styrene–butadiene–styrene block rubbers, one with 10wt% calcium carbonate filler (S6C), and one without (S6) were surface treated with UV radiation. The resulting surface modifications and adhesion properties with polyurethane adhesive were studied. The surface modifications produced on these…

Thermoplastic polyurethane (TPU) adhesives containing nanosilicas with different specific surface area and silanol group content were prepared and characterized by FTIR spectroscopy, differential scanning calorimetry (DSC), thermogravimetry (TGA), X-ray diffraction, plate-plate rheology, dynamical–mechanical–thermal analysis (DMTA), transmission electron microscopy (TEM), and…

A revision of the calpionellid bio-chronostratigraphy in Western Sicily (Italy)
was carried out, in order to update the taxonomy of this group, through the
identification of some genera (Borziella, Longicollaria, Chitinoidella, Dobeniella,
Sturiella, Borzaiella and Praecalpionellites) and species (Remaniella
catalanoi…

The goal of this work was centered in the graph visualization. The hope is that the extra dimension would give, literally, more space, and that this would ease the problem of displaying large structures. In spite of their apparent simplicity,…

This thesis describes the design, implementation and evaluation of FPGA Architecture of a Digital ANN (Artificial Neural Networks) by using four components: data memory, weights memory, neuron module, and control unit. All these components have a generic orthogonal structure in…

In this thesis, we emphasized the need to use multiple node-disjoint paths between a given source and destination. The use of node-disjoint paths not only allows different paths to share the traffic, but also provides fault-tolerance to some extent. However,…
