The oxidation of aniline with ammonium peroxydisulfate in the presence of gelatin yields spindle-like colloidal polyaniline particles having the particle size smaller than 200nm. The similar oxidation of aniline with silver nitrate leads to hybrid composite polyaniline–silver nanoparticles with more complex morphology. The composites were characterized by transmission electron microscopy, dynamic...
The presented study is focused on the development of LiFePO4 based cathode for thin and flexible screen printed secondary lithium based accumulators. An ink formulation was developed for the screen printing technique, which enabled mass production of accumulator's cathode for Smart Label and Smart Textile applications. The screen printed cathode was compared with an electrode prepared by the bar coating...
The contribution treats the topic of data transformation for classification of indications in the field of non-destructive defectoscopy by eddy-currents. Four algorithms for transformation of measured signal indications into suitable vectors of features will be presented. The contribution concentrates on the choice of coefficients from single or multiple vectors of features to define new data representation...
The contribution treats the topic of analysis of deformations sources of images of visualized transparent polymeric foils by the schlieren methods and by the methods of image processing. The brightness deformations are rectifiable by means of schlieren apparatus setting and by the methods of image processing. A new method of brightness deformation correction by the linear regression model is presented...
The contribution treats the topic of processing the experimentally gained information on the properties of optically transparent polymeric foils. Schlieren optical system was used to examine and visualize refractive index distribution. Experimental results of statistical and frequency approach to classification of different types of polymeric foils into classes are compared.
Fast localization and classification of defects and structure elements in the defectoscopy of steam generator tubes is the field where application of wavelet transformation is very perspective. Presented paper recapitulates possible applications of wavelet transformation in different subtasks of process analysis of output signal from measurement probe based on eddy-currents.
