Challenging analytical task: analysis and monitoring of arsenic species in water
(Environmental Engineering and Management Journal, 2014)
Analysis and monitoring of arsenic is still a challenging analytical task. Due to its complex behaviour (different forms of arsenic that can be present depending on pH and oxidation states of arsenic) as well as demanding ...
Simultaneity analysis in a wireless sensor network
(Polish ACAD Sciences Committee Metrology and Res Equipment, 2015)
An original wireless sensor network for vibration measurements was designed. Its primary purpose is modal analysis of vibrations of large structures. A number of experiments have been performed to evaluate the system, with ...
Corroded scale analysis from water distribution pipes / Analiza korozionih ljuski u vodovodskim cevima
(Savez hemijskih inženjera, Beograd, 2011)
The subject of this study were the steel pipes that are part of Belgrade's drinking water supply network. In order to investigate the mutual effects of corrosion and water quality, the corrosion scales on the pipes were ...
Modelling behaviour of bridge pylon for test load using subspace method
(Zvava Geodetov Slovenije, 2015)
This paper presents the procedure of structure behaviour analysis and modelling applying the subspace method, which has been used in system identification but not in geodetic practice. This method enables the state space ...
Fire-resistance prognostic model for reinforced concrete columns
(Croatian Association of Civil Engineers, 2012)
The prediction model used for defining fire resistance of reinforced concrete columns exposed to standard fire from all four sides is presented in the paper. The proposed model relies on the concept of artificial neural ...
Testing heuristic optimisation methods for vibration-based detection of damage
(Union of Croatian Civil Engineers and Technicians, 2016)
Considerable efforts have been made in recent years for the development of non-destructive techniques for detection of structural damage based on changes of dynamic parameters of structures. The tests are made on a model ...
Stabilization of fine-grained soils with fly ash
(Union of Croatian Civil Engineers and Technicians, 2015)
Results of laboratory research focusing on soil stabilization, using fly ash without activators, are presented in the paper. Two types of fine-grained soils were tested: low to medium plasticity clay and very expansive, ...
Technical implementation of the national spatial data infrastructure in Serbia
(Strojarski Facultet, 2017)
The paper provides overview of research and studies covering implementation and development of the National Spatial Data Infrastructure (NSDI) concept in Serbia. Research had been done in 2011 divided by 2013, with the ...
Reply to the Discussion by Chen on "Traffic-induced vibrations of frame structures"
(Canadian Journal of Civil Engineering, 2013)
A generalization of nil-clean rings
(Miskolc Mathematical Notes, 2018)
The conditions that allow an element of an associative, unital, not necessarily commutative ring R, to be represented as a sum of (commuting) idempotents and one nilpotent element are analyzed. Some applications to group ...
