On a generalized Jordan normal form of an infinite upper triangular matrix
(Taylor & Francis Ltd, United Kingdom, 2019)
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal form.

Forming a Regular Pentagon, Decagon and Pentagram Using Origami Technique
(Belgrade: Mathematical Institute SASA, 2010)
Forming a regular pentagon, decagon and pentagram using origami technique is based on the construction of approximately 36oangle by dint of A4 paper of format. The implemented method is “fold and cut”. ...
How does light move?: Determining the flow of light without destroying interference
(Europhysics News, 2013)
Young's two-slit experiment constitutes the paradigm of quantum complementarity. According to the complementarity principle, complementary aspects of quantum systems cannot be measured at the same time by the same experiment. ...
Understanding interference experiments with polarized light through photon trajectories
(Annals of Physics, 2010)
Bohmian mechanics allows to visualize and understand the quantum-mechanical behavior of massive particles in terms of trajectories. As shown by Bialynicki-Birula, Electromagnetism also admits a hydrodynamical formulation ...
Numerical modelling of temperature fluctuations in superchilled fish loins packaged in expanded polystyrene and stored at dynamic temperature conditions
(International Journal of Refrigeration-Revue Internationale Du Froid, 2012)
An appropriate thermal insulation of fresh fish packaging can substantially reduce negative effects of poor temperature management in chill chains. The aim of the current study is to experimentally and numerically investigate ...
Wireless system for sleeper vibrations measurement
(Communications - Scientific Letters of the University of Zilina, 2014)
This paper describes testing of a wireless technique for measuring the actual sleeper vibrations and determination of their dynamic deflection based on the experimentally acquired acceleration data. Practical measurements ...
Selected methods of collecting and processing field data for reconstruction of the single nave church
(Central Institute for Conservation, Belgrade, 2016)
Modern technologies enable high-precision collecting of field data and its processing in order to create documentation, perform various analyses or reconstruction of buildings that are an important part of cultural heritage. ...
Note on Strongly Nil Clean Elements in Rings
(Springer New York LLC, 2019)
Let R be an associative unital ring and let a R be a strongly nil clean element. We introduce a new idea for examining the properties of these elements. This approach allows us to generalize some results on nil clean and ...
Influence of femtosecond pulsed laser irradiation on bismuth germanium oxide single crystal properties
(Elsevier Ltd, 2016)
High quality bismuth germanium oxide single crystals were irradiated by a femtosecond pulsed laser beam of increasing power. Analyses performed on irradiated and unirradiated samples showed significant changes in transmittance, ...
