Nonsingular acyclic matrices with full number of P-vertices
(Linear & Multilinear Algebra, 2013)
We classify the trees for which there is a nonsingular matrix where each vertex is a P-vertex. In particular, we show that such trees have an even number of vertices. Both results provide answers to questions proposed by ...
Extreme flood reconstruction by using the 3DNet platform for hydrological modelling
(Journal of Hydroinformatics, 2018)
Notwithstanding recent advances in hydrological modelling, flood simulations remain challenging since many processes must be simulated with high computational efficiency. This paper presents a novel geographic information ...
Numerical modeling of hypolimnetic oxygenation by electrolysis of water
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The paper presents a novel method for hypolimnetic oxygenation by electrolysis of water. The performance of the method is investigated by the laboratory and the field experiment. The laboratory experiment is conducted in ...
Haplotype variation in the Physa acuta group (Basommatophora): genetic diversity and distribution in Serbia
(Hellenic Centre for Marine Research, 2016)
The genus Physa (= Physella) includes the most abundant and diverse freshwater gastropods native to North America. Due to their invasive nature, many species occur throughout the world. The most abundant species, Physa ...
Bending behaviour of glulam beams reinforced with carbon FRP plates
(Taylor and Francis Ltd., 2015)
The idea of reinforcing glued laminated timber (glulam) beams came in response to the need to improve the mechanical properties, as well as to ensure higher reliability of this type of structural elements. This paper ...
Crawling the construction web - A machine-learning approach without negative examples
(Applied Artificial Intelligence, 2008)
Professionals and craftsmen in the construction sector make an intensive use of information in their decision-making processes but only make limited use of the abundant information, that is potentially available to them, ...
Electromagnetic energy flow lines as possible paths of photons
(Physica Scripta, 2009)
Motivated by recent experiments where interference patterns behind a grating are obtained by accumulating single photon events, we provide here an electromagnetic energy flow-line description to explain the emergence of ...
Maintenance of the state survey in the Republic of Montenegro
(Survey Review, 2018)
The paper provides an overview of the maintenance of the state survey, as the foundation for the development of the geodetic infrastructure, real estate cadastre, mapping and the National Spatial Data Infrastructure (NSDI) ...
Development of new models for the estimation of deformation moduli in rock masses based on in situ measurements
(Springer Verlag, 2018)
Knowledge of the deformation properties of the rock mass is essential for the stress-strain analysis of structures such as dams, tunnels, slopes, and other underground structures and the most important parameter of the ...
Subtle inconsistencies in the straightforward definition of the logarithmic function of annihilation and creation operators and a way to avoid them
(Journal of Physics A-Mathematical and Theoretical, 2009)
Using the resolution of identity spanned by coherent states of the harmonic oscillator, any entire function of the creation and the annihilation operators and its action on a vector in Hilbert space can be defined directly ...
