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 ...
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, ...
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 ...
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 ...
Recognition of common areas in a web page using a visualization approach
(Artificial Intelligence: Methodology, Systems and Applications, Proceedings, 2002)
Extracting and processing information from web pages is an important task in many areas like constructing search engines, information retrieval, and data mining from the Web. Common approach in the extraction process is ...
Numerical modelling of supercritical flow in circular conduit bends using SPH method
(China Ocean Press, 2017)
The capability of the smoothed-particle hydrodynamics (SPH) method to model supercritical flow in circular pipe bends is considered. The standard SPH method, which makes use of dynamic boundary particles (DBP), is supplemented ...
Converging stepped spillway flow
(Taylor and Francis Ltd., 2016)
Wall deflection in supercritical flow induces standing waves which significantly influence the flow field close to the wall. This paper analyses the flow in the converging stepped spillway, using two scale-models with ...
Delamination detection in woven composite laminates with embedded optical fibers
(Wiley-VCH Verlag, 2001)
