Identification of movements using different geodetic methods of deformation analysis
(Geodetski vestnik, 2015)
This paper is based on comparative analysis of applied analysis methods on geodetic networks deformation, based on two-dimensional components of GNSS baseline vectors simulated by two epochs, for the purpose of identifying ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(Materials Science Forum, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
Identification of flutter derivatives by forced vibration tests
(Union of Croatian Civil Engineers and Technicians, 2017)
Results of an experimental study related to flutter phenomenon are presented in the paper. Two cross-sections are considered: a rectangular cross-section and a typical symmetric bridge cross-section. Stationary coefficients ...
Modelling behaviour of bridge pylon for test load using regression analysis with linear and non-linear process / Modeliranje ponašanja pilona mosta na probno opterećenje primjenom regresijske analize kao linearan i nelinearan proces
(Geodetski list, 2011)
This paper presents the procedure for dynamic system identification regarding behaviour of bridge pylon for test load, and the numeric example had been illustrated by examination of "Sloboda" bridge in Novi Sad. Since pylon ...
Evaluation of the fourier transform of e(-ux2) for imaginary U
(Springer Science and Business Media Deutschland GmbH, 2006)
It is shown that the Fourier integral of the function exp(-ux(2)) exists not only for u satisfying Re u gt 0 but also for u that satisfies Re u >= 0. The proof is given by evaluating this integral for imaginary u.
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 ...
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. ...
