Time-Frequency Analysis of Nonstationary Optical Signals Using Husimi Type Function
(Polish Academy of Sciences, 2009)
Time-frequency analysis is important to identify the localized information of a non-stationary signal in the time and frequency domains simultaneously. There are few different time-frequency analysis methods available with ...
Application of geological strength index for characterization of weathering-induced failures
(Union of Croatian Civil Engineers and Technicians, 2018)
This study investigates weathering indded failures of the heterogeneous fissile rock mass consisting of sandstone and shale. Discontinuity data was collected and the geological strength index (GSI) value was determined ...
Application of 3D animation principles and tools in geometrical education
(DRUNPP, Sarajevo, 2013)
Geometrical education using 3D animation principles and tools represents a new methodology approach and its final result is presented on new way,
as multimedia tool. The originality of the paper is based on interdisciplinary ...
Rail defects head checking on the Serbian railways
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2014)
The rail defects due to rolling contact fatigue represent serious safety hazard for rail traffic all around the world. That hazard is more distinct on railways without adequate maintenance strategy, with the increase of ...
A generalization of nil-clean rings
(Miskolc Mathematical Notes, 2018)
The conditions that allow an element of an associative, unital, not necessarily commutative ring R, to be represented as a sum of (commuting) idempotents and one nilpotent element are analyzed. Some applications to group ...
Behaviour of electron content in the ionospheric d-region during solar x-ray flares
(Astronomska opservatorija, Beograd i Univerzitet u Beogradu - Matematički fakultet - Odeljenje za astronomiju, Beograd, 2016)
One of the most important parameters in ionospheric plasma research, also having a wide practical application in wireless satellite telecommunications, is the total electron content (TEC) representing the columnal electron ...
Damage Detection for Civil Structural Health Monitoring Application - A Case Study of the Steel Grid Bridge Structural Model
(Strojarski Facultet, 2018)
The procedure for detecting the location and severity of damage of complex structural systems using their modal properties is an important tool of Structural Health Monitoring (SHM) of civil infrastructure. The herein ...
Laser Interaction with Material - Theory, Experiments and Discrepancies
(Polish Academy of Sciences, 2009)
The experimental treatment of chosen material with laser beams, starting from continuous wave up to fs pulses, produces the necessity to find the common and sophisticated theoretical approaches to interaction modeling. For ...
Variations of total electron content over Serbia during the increased solar activity period in 2013 and 2014
(Zvava Geodetov Slovenije, 2016)
To understand general ionosphere properties over Serbia, an analysis of temporal and spatial ionosphere Total Electron Content (TEC) over the region was performed. The present research focuses on daily, seasonal and spatial ...
Specific features of stainless steel compression elements
(Union of Croatian Civil Engineers and Technicians, 2015)
Stainless steel has a number of features that define different behaviour of structural elements made of this material, as related to equivalent carbon steel elements. These properties, especially prominent in case of ...
