On Wheeler's delayed-choice Gedankenexperiment and its laboratory realization
(Physica Scripta, 2011)
We present an analysis and interpretation of the experiment performed by Jacques et al (2007 Science 315 966), which represents a realization of Wheeler's delayed-choice Gedankenexperiment. Our analysis is based on the ...
On the influence of resonance photon scattering on atom interference
(Physica Scripta, 2010)
Here, the influence of resonance photon-atom scattering on the atom interference pattern at the exit of a three-grating Mach-Zehnder interferometer is studied. It is assumed that the scattering process does not destroy the ...
Experimental Study: How fast is the Children's Reaction Times for Different Heights of Traffic Signs - Ergonomic Principles and Traffic Safety Aspect
(International Engineering and Technology Institute (IETI), 2019)
Touchscreen devices have dramatically increased the accessibility and usage of technology, causing escalating usage, especially by very young children. Although the effects of screen time have been shown to produce serious ...
Geometry of twisted surfaces applied on horizontal communications in architecture / Geometrija spiralnih površi primenjena na horizontalne komunikacije u arhitekturi
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2013)
Contemporary technologies and materials continuously challenge structural designers, as well as architects, to achieve unique applications of various geometric surfaces. Twisted structures are actual and numerous in building ...
Simultaneity analysis in a wireless sensor network
(Polish ACAD Sciences Committee Metrology and Res Equipment, 2015)
An original wireless sensor network for vibration measurements was designed. Its primary purpose is modal analysis of vibrations of large structures. A number of experiments have been performed to evaluate the system, with ...
The measurement of inclination on gravity concrete dams using the tiltmeter instrument / Merenje nagiba kod gravitacionih betonskih brana primenom instrumenta tiltmetar
(Savez inženjera i tehničara Srbije, Beograd, 2015)
The measurement of inclination on gravity concrete dams using the instrument tiltmeter is described and discussed with special reference on obtained results on the dam 'Đerdap 2' acquired in the three years period. Tiltmetar ...
An experimental study on the certain effects of colors on the perception of preschool and primary school children – implications to design
(IETI Transactions on Ergonomics and Safety, 2019)
The adult ergonomic design principles usually do not apply to children, because their needs, skills, and expectations differ. The purpose of this study is to explore preschoolers' and primary schoolers' color perception ...
Variations of Concave Pyramids of Second Sort with an Even Number of Base Sides
(Bucharest, Romania: SORGING–ROMANIAN SOCIETYFORENGINEERINGGRAPHICSBrasov, Romania: University ‘Transilvania’ of Brasov, 2015)
Concave pyramids of second sort (CP II) are formed similarly to concave cupolae of second sort
(CC II) with a comparable logic of emergence to the regular-faced convex pyramids. They are formed by enclosing the space over ...
Preparation and characterization of bismuth germanium oxide (BGO) polymer composites
(Elsevier Ltd, 2017)
Bismuth germanium oxide Bi12GeO20 (BGO) has very interesting electrical, optical and magnetic properties. In order to make devices based on this material more flexible, its powder was used for preparing polymer composites. ...
Full quantum mechanical analysis of atomic three-grating Mach-Zehnder interferometry
(Academic Press Inc., 2015)
Atomic three-grating Mach Zehnder interferometry constitutes an important tool to probe fundamental aspects the quantum theory. There is, however, a remarkable gap in the literature betweenthe oversimplified models and ...
