AB  - RTI (eng: Reflectance Transformation Imaging) je računarska fotografska metoda koja snima oblik i boju površine objekta sinhrono sa osvetljavanjem iz različitih uglova. RTI, takođe, dozvoljava matematičko modelovanje površine i atributa boja posmatranog objekta. Funkcije poboljšanja RTI otkrivaju površinske informacije koje se ne uočavaju pri normalnom osvetljenju i ispitivanju. U radu je prikazano jedno savremeno rešenje hardvera i softvera aparature za izradu serije fotografija nad jednom površinom osvetljenom iz više pravaca sekvencijalno. Dalja obrada vrši se uz pomoć javno dostupnog softvera RTIViewer. Opisani sistem je korišćen za RTI snimanje površina, dat je prikaz ispitivanja površine novčića i objašnjena prednost i mogućnost primene u mašinstvu i ostalim tehničkim naukama.
AB  - RTI (Reflectance Transformation Imaging) is a computer photographic method that
captures the shape and color of the surface of an object synchronously with lighting from different angles. RTI also allows mathematical modeling of the surface and color attributes of the observed object. RTI enhancement functions reveal surface information that is not observed under normal lighting and testing. The paper presents a modern solution of hardware and software for the production of a series of photographs over a single surface illuminated from several directions sequentially. Further processing is performed thanks to the publicly available RTIViewer software. The described system was used for RTI imaging of surfaces, a presentation of the examination of the surface of coins was given and the transferability and possibility of application in mechanical engineering and other technical sciences were explained.

AB  - Although conservative, the construction industry must be transformed in line with new technologies. Adopting the concept of 3D printing can provide a handful of benefits in terms of creativity, flexibility, less waste generation, more efficient energy consumption as well as lower carbon emissions. The aim of this paper is to summarize the basic principles of 3d concrete printing, discussing the main goals and shortcomings that must be considered and resolved before wider application. Also, a review will be given on the production technology and materials used, as well as the sustainability of buildings built using the concept of 3d printing.

AB  - Although a most prominent material in contemporary construction practice due to
its’ obvious advantages, concrete incorporates a number of drawbacks. It is one of the most advantageous principles for decades to enable a large-scale on-site application of this materials with acceptable properties, needed to withstand specific conditions. A concept of 3d printing concrete presents a promising ground for further improvement of this principle. While maintaining as much as possible of the prerequisite and common properties to answer the construction demands, this material has to evolve as much as possible to fulfill the 3d concept, which would, in turn, pave a way for next level of its wide range of construction applications. This paper aims to contain main principles of 3d printing concrete, discussing the main goals and the drawbacks that have to be addressed and solved prior to wider application. Also, wind tower construction, as a specific construction will be discussed as a potentially promising ground for this old construction material dressed in a new suit.
AB  - Iako je najčešće primenjivan materijal u savremenoj građevinskoj praksi zbog svojih očiglednih prednosti, beton poseduje izvestan broj nedostataka. Jedan od najvažnijih principa već decenijama je da se omogući masovna upotreba ovog materijala na gradilištima sa prihvatljivim svojstvima, neophodnim da bi on podneo specifične uslove. Koncept 3d štampe betona predstavlja obećavajuću osnovu za dalje poboljšanje ovog principa. Zadržavajući što veći broj preduslova i osnovnih svojstava da bi se zadovoljili konstruktivni zahtevi, ovaj materijal mora umnogome evoluirati da bi zadovoljio 3d concept, što bi, zauzvrat, popločalo put do sledećeg nivoa njegovog širokog obima primene u graditeljstvu. Cilj ovog rada je da sadrži osnovne principe 3d štampe betona, diskutujući glavne ciljeve I nedostatke koji se moraju sagledati i rešiti pre šire primene. Takođe, konstrukcija stuba vetrogeneratora, kao specifična konstrukcija biće diskutovana kao potencijalno obećavajuća osnova za ovaj stari građevinski materijal odeven u novo odelo.

AB  - Pulse reverse power modes are used in order to obtain metal coatings with similar or better characteristics, compared with the coatings produced by constant current. Pulse reverse modes increase production and energy efficiency of electroplating cells with the use of higher density currents. In this paper, we investigate optimisation of systems for standard electrodeposition by choosing the suitable duration and intensity of the pulses. It was shown that energy efficiency of the process can be achieved with satisfactory quality of coatings and without expensive and often dangerous additives in the electrolyte.
