Study of supermolecular structure of polymers by light scattering methods
Holoubek, Jaroslav
Various optical techniques, especially light scattering methods, have been investigated as potential candidates for characterization of multiphase polymeric materials, i.e. to measure the size, shape and volume fraction of the minor phase and time evolution of morphology. Some supplementary information has been also obtained from model calculatios of dispersed-phase particles changes, time-resolved light scattering experiments and image analysis.

Application of image analysis in research into geocomposite materials
Ščučka, Jiří
The paper concerns possibilities of the image analysis application to the qualitative and quantitative evaluation of structure and texture of geocomposite materials - the noncohesive rocks injected with polyurethane resins. Understanding the relation between the structure and texture and physical mechanical properties of the materials represents one of the ways, how to determine indirectly probable properties and behaviour of geocomposites formed in practical applications.

Obrazová analýza pohybu struktur uvnitř buněk
Matula, Pe. ; Ondřej, Vladan ; Kozubek, Stanislav
Analysis of time-lapse series of images of living cells requires automation. This contribution concerns the main features of the software package developed for this purpose in our laboratory. Some improvements of our recently published method for tracking of sub-cellular structures based on graph theory are presented. The behaviour of the method is evaluated on images of centromeric heterochromatin defined by HPlbeta-GFP fusion protein. The results show that the method is very well applicable for this type of data.

Quantitative image analysis of precipitates in Ni-rich NiTi shape memory alloys
Bojda, Ondřej ; Dlouhý, Antonín ; Fiala, J.
A microstructure of a Ti-50.7at%Ni shape memory alloy resulting from solution annealing and subsequent aging at 500°C/3.6ks/8MPa is quantitatively analysed. The TEM study is assisted by Adaptive Contrast Control (ACC) routines embedded in a recent image processing system. The assessment focuses on the number density, size and distribution of crystallographic variants of Ni4Ti3 precipitates. It was found that the distribution of crystallographic particle variants in the microstructure is inhomogeneous. The influence of the heterogeneous Ni4Ti3 precipitation on the characteristics of the martensitic transformation B2®B19´ is briefly discussed.

The Communication Strategy of the Siemens Company and the Analysis of Its Efficiency
Maleninská, Eva ; Král, Petr (advisor) ; Karlíček, Miroslav (referee)
This thesis is focused on communication strategy of the Siemens company with emphasis on the communication activities of the Czech companies of the Siemens group and on the particular marketing campaign. The theoretical part explains the term "communication strategy" and describes the process of marketing communication and various models referring to the marketing communication. Furthermore, it characterizes particular tools of the communication mix and also deals with marketing research. The practical part provides general information about the Siemens company and a description of the communication activities of the company which are focused on the increase of the brand knowledge and strenghtening of the company image. This part also deals with the changes in the communication strategy after 2003 and the characterization of the Czech marketing campaign "We Like Being In the Czech Republic". The evaluation of the effects of the performed changes and the marketing campaign for the image of the Siemens company is the content of the final chapter. This evaluation results from the findings of the image analyses carried out by an independent research agency.
