Flaw acceptability assessment detected in HSLA steel weld joints
Inoslav Rak, 1999, original scientific article

Abstract: The flow size in weld joint can be determined by non destructive examination (NDE). Because of different mateials, and loading as well as because of the possible effect of corrosive environment the question arises how to assess reliably the allowable falw size in different weld joint parts. The presence of flaws is obvious but the possibilities of their revealing are limited and not always posssible. The flaw size and distribution are the essential parameters for the structure capacity of bearing under high loading the weld joint. The larger is the allowable flaw size anticipated, the safer is the welded structure, and the easiest is the detection of the flaw size by NDE methods. Thus for assessing the safety of complex loaded welded structure, machine parts or equipment life time, it is obligatory to consider the requirements of different "Fitness for Purpose" systems. The article presents the possibility of assessing the detected flaw by means of NDE if the material fracture toughness of the area where the fatigue crack tip located is known. The fatigue crack represents the severest discontinuity that can occur in a welded joint. The principles of IIW Guidance on Assessment of The Fitness for Purpose of Welded Structures - IIW/IIS-SST-1157-90 and BS PD 6493 and separately ETM that treats mis-matched weld joints are shown and used.

IZBOLJŠAVE PRI TRŽENJU IZPOSOJE VOZIL
Janja Frankič, 2012, undergraduate thesis

Abstract: V pričujočem diplomskem delu smo na primeru podjetja Oskar Rent d.o.o. predstavili možne izboljšave na področju trženja storitev izposoje vozil. V prvem delu naloge smo z ugotovitvami avtorjev, njihovimi mnenji in izsledki na področju preučevanja trženja, ki so potrebni za uspešno prodajanje storitev, opredelili splošne teoretske osnove. V nadaljevanju smo diplomsko delo usmerili v praktične raziskave in predloge za izboljšave ter inovacije na področju marketinga podjetja Oskar Rent d.o.o. Raziskavo smo izvedli z anketnim vprašalnikom, pri tem pa smo se osredotočili na osrednjo slovensko regijo.
Keywords: izposoja vozil, spletni sistemi, trženje, marketinško informacijski sistem (MIS).
