The material quality, the deformation rate, the temperature and the stress state influence mechanical behaviour and properties of different materials. Due to this great variety of the influencing factors we do not have one general model describing the behaviour of materials; then again we have to use a great number of material constants in order to characterize the material properties. The exponents of the Manson-Coffin, the Basquin and the Paris-Erdogan laws were applied for the verification of the connection among the fatigue fracture types. Own measured values and test results that can be found in the literature were used for the illustration of the connections. “Fracture surface”-s can be determined for characterizing the behaviour of different steel and aluminium grades and their welded joints, under cyclic loading conditions. It can be concluded that “fracture surface”-s are suitable for describing the fracture behaviour and the conversion of different fracture parameters of different steels and aluminium alloys.

Nowadays more and more vast cities and facilities are built but we don’t have enough knowledge to orientate ourselves in them. That is why navigation systems were created to relieve our lives. Even if GPS-based outdoor navigation systems are accurate and useful methods, yet, we don’t have any precise and widespread techniques for indoors navigations. On account of the monumental complexes we have indoor navigation systems are must-have. These can be a helping hand for visually impaired people who, due to their situation, have different expectations for such a system. Of course, only graphical user interface is not enough to be useful but the options displayed on the screen should also be translated into sounds. Moreover, visually impaired people need to get more information about the environment where they are.
