Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Real-time forecasting urban drainage models: full or simplified networks?
(Water Science and Technology, 2010)
Lead time between rainfall prediction results and flood prediction results obtained by hydraulic simulations is one of the crucial factors in the implementation of real-time flood forecasting systems. Therefore, hydraulic ...
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 ...
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 ...
Assessment of sleeper support conditions using micro-tremor analysis
(SAGE Publications Ltd, 2016)
An irregular geometry of the track can influence the safe passage of railway traffic. Therefore, maintenance activities on railways are mostly directed towards the correction of track geometry. It has been shown that ...
Negative binomial states for the pseudoharmonic oscillator
(Physica Scripta, 2013)
In this paper we examine some of the statistical properties of the negative binomial states (NBSs) that are a superposition of the number of states with appropriately chosen coefficients, but on the basis of Fock-vectors, ...
