- Magnetostrictive – piezoelectric sensors on the base of multiferroic electroceramics. Project Leader: dr Agata Lisińska-Czekaj
The trend for miniaturization of electronic components necessitates the replacing of magnetic sensors with primary and secondary windings, which sensors using complex methods of energy transformation but free from electric windings that are usually not suitable for miniaturization purposes.
The application of electroceramic multiferroic structures in developing a new generation of energy converters as well as electronic units makes it possible to improve the electric parameters of the electronic circuits (e.g. small power consumption, small losses), at the same time providing both a simple way of control (also with a possibility of intelligent/smart system functions) and decreasing the manufacturing costs. The aim of the project is 1) to develop a new electroceramic material with multiferroic properties on the basis of multi-component oxide systems exhibiting the perovskite-type structure (PTS); 2) to develop a technology of fabrication of functionally graded multiferroic ceramics; 3) to investigate the unique properties of the PTS – type multiferroic materials from the point of view of their application for fabrication of energy converting transducers; 4) to develop the construction of a electroceramic magnetostrictive-piezoelectric sensor.
- Duplex layers on an aluminium oxide base. Project Leader: prof. UŚ dr hab. Władysław Skoneczny
The two technologies for obtaining “duplex” tape surface layers were worked out.
The process of layers production was divided into two stages: the obtainment of the layer of aluminium oxide by the electrolytic method and thermal treatment in a solid medium consisting of graphite dust. In the first stage, the surface has been placed for the anodizing oxidation process in electrolyte, based on a hydrous solution of the following acids: sulphuric, phthalic and oxalic. The introduction of graphite into the structure of aluminium oxide was achieved during thermal treatment in a solid medium consisting of graphite dust. The carbonizing process was completed through the cleaning of the samples with compressed air.
- Computer analysis of the mechanical properties of bone microstructure using model of spatial distribution of density. Project Leader: dr Marcin Binkowski
The main aim of the project is to perform a study which allows for the identification of the biomechanical properties of the bone microstructure. It will be performed based on the model of spatial distribution of bone density which is defined based on quantitative micro-computed tomography.
The definition of the high resolution numerical model allows for strength analysis and the prediction of mechanical properties of the modeled bone. The results will be applied in clinical studies, such as the quantitative analysis of bone biopsy, which usually are analyzed by destructive sectioning.
- Analysis of eye tomographic images. Project Leader: dr inż. Robert Koprowski
An optical tomography is a modern non-invasive technique for tissue section imaging, in this case of the eye’s retina, using the light scattered on individual layers of the examined tissue. Spectral tomography, as compared with the previous solutions (e.g. time tomography), features much higher resolution. The elimination of a moving mirror, necessary to deeply scan into the examined object, also allows for a shortening of the examination time (object scanning), approximately a hundred times. The short time of scan performance, as well as its sequentiality and the maintaining of a constant shift allows for the obtaining of 3D images.
The project is aimed at developing a software program which should enable a fully automated analysis of individual fractions visible on 2D images and thereby render their 3D reconstruction. So, in this case the key issue becomes the algorithm using both known and also new (developed under this project) techniques of image processing, enabling a fully automated separation of characteristic areas on eye tomographic images.
A significent result of the project will be not only developing the above-mentioned algorithm, but also preparing a monograph “Automated methods of eye tomographic images analysis”.
- Analysis and enhancing digital fingerprint images. Project Leader: prof. UŚ dr hab. Piotr Porwik
In the supervisor’s research grant, the investigations are carried out collectively with the Central Forensic Laboratory of the Polish Police Fingerprint Department, Warsaw. In these research studies, attempts are undertaken to acquire of biometric data based on separated data of fingerprint records. The new image processing technique is designed and tested by a doctoral student of the Computer Systems Department, University of Silesia, Katowice. Investigation results will be published and the prepared software will be used in different Polish police departments, especially by the Fingerprint Department.
