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, ...
Layer-specific spatial prediction of As concentration in copper smelter vicinity considering the terrain exposure
(Elsevier B.V., 2017)
Prevailing climatic conditions and local topography can be classified as the most influential environmental factors that affect the spatial dispersion of pollutants emanating from industrial sources. In this study, the ...
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 ...
Hysteretic behavior of rectangular tube (box) sections based on Preisach model
(Archive of Applied Mechanics, 2012)
In the present paper, the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
Sparse regression interaction models for spatial prediction of soil properties in 3D
(Elsevier Ltd, 2018)
An approach for using lasso (Least Absolute Shrinkage and Selection Operator) regression in creating sparse 3D models of soil properties for spatial prediction at multiple depths is presented. Modeling soil properties in ...
Alkali-activated concrete with Serbian fly ash and its radiological impact
(Elsevier Ltd, 2017)
The present paper reports the results of a study on different types of fly ash from Serbian coal burning power plants and their potential use as a binder in alkali-activated concrete (AAC) depending on their radiological ...
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 ...
Calibration of a 1D/1D urban flood model using 1D/2D model results in the absence of field data
(Water Science and Technology, 2011)
Recently increased flood events have been prompting researchers to improve existing coupled flood-models such as one-dimensional (1D)/1D and 1D/two-dimensional (2D) models. While 1D/1D models simulate sewer and surface ...
