An intensity based optical fiber sensor for low velocity impact detection in unidirectional composites
(Advanced Composite Materials, 2000)
Prevention df serious damage of composite structures might be achieved by inspecting the structural integrity during exploitation. This paper decribes the design and development of a promising optical fiber sensor system ...
Fracture of reinforced concrete beams subjected to three point bending
(International Journal of Damage Mechanics, 2003)
The present paper investigates deformation of three point bent reinforced concrete (RC) beams analytically (using fracture mechanics), computationally (using finite element method) and experimentally. As the applied force ...
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 ...
Coherent Beam Splitting by a Thin Grating
(Polish Academy of Sciences, 2009)
The wide use of beam splitters in quantum interferometry, attosecond metrology, modern quantum information processing, foundations of quantum mechanics, has been based on coherence of beams emerging from a beam splitter. ...
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 ...
Bending Resistance of Composite Sections with Nonductile Shear Connectors and Partial Shear Connection
(Hindawi Limited, 2018)
The paper presents the nonlinear section analysis for composite steel-concrete beams with different degrees of shear connection. The analysis is fiber based, i.c., integration over the cross section is performed numerically, ...
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 ...
