PR 2.0 - The role of new media in the building of public relations
Dobrovská, Jana ; Šlerka, Josef (advisor) ; Zbiejczuk, Adam (referee)
The diploma thesis "PR 2.0 - The role of new media in the building of public relations" deals with the application of new media to the process of building links with public with help of public relations tools. The target of this thesis is to provide a comprehensive outlook on options of using new media and their influence on a transformation of communication paradigm of the public relations discipline. It focuses particularly on social media that form one of the new media categories. The theoretical part follows basic definitions and key characteristics of the public relations discipline, new and social media and main differences between the "old" and "new" media. It is dealt with the implementation of social media to the process of building relations with public and their role and contribution for the public relations discipline. As an own contribution to the thesis I conducted a research. The analytical part explores particular case studies of implementation of social media to public relations activities. The case studies and their analysis are supposed to validate or invalidate the hypothesis of the influence of new media on changing paradigm of public relations.
Modelling of the carbon diffusion coefficients temperature dependence in the welded joint of steels
Řeháčková, L. ; Dobrovská, J. ; Million, Bořivoj ; Stránský, K.
This contribution contains the results of measurement of carbon redistribution ithe welded joint of low-alloy CrNiMoV steel and low-alloy Si steel. The measurements was carried out in the range of temperatures 500-1000°C. On the basis of the measured concentration data the carbon diffusion coefficients were calculated and also their temperature dependences were determined
Mathematic model for prediction of the ductile iron structure
Stránský, K. ; Šenberger, J. ; Musilová, I. ; Million, Bořivoj ; Dobrovská, J.
The paper deals with a original thermodynamic model of growth of graphite in spheroidal graphite cast iron. The model, which is based on the using of equations of mathematic physics and of thermodynamic, diffusion and phase data, describes of graphite growth in liquid and solid phase of Fe-C-M system.
On modelling of the diffusion phenomena in the selected welded joints of steels
Řeháčková, L. ; Million, Bořivoj ; Dobrovská, J. ; Stránský, K.
Measurement of carbon redistribution was carried out in temperature range 500-750oC in two types of the welded joints (low-alloy Si steel/alloy CrNiMoV steel and low-alloy Si steel/ austenitic Cr18Ni9 steel). For approximation of the measured concentrations of carbon there were applied the relations representing solution of the stationary model of carbon redistribution i.e. classical method of solution of diffusion with help of the error function.
