Linear light amplifier and amplification of N-photon states
(Springer Science, 2019)
We consider a linear quantum amplifier consisting of NA two-level atoms and study the problem of
amplification of N-photon states. The N-photon states are associated with N-quantum states of the
harmonic oscillator. We ...
Tiling the Lateral Surface of the Concave Cupolae of the Second Sort
(Birkhauser Verlag AG, 2019)
As architectural structures, concave cupolae of the second sort (CC II) are suitable for prefabrication, thanks to the uniformity of their elementsregular polygons. This paper discusses ways to subdivide the lateral ...
Concave deltahedral rings based on the geometry of the concave antiprisms of the second sort
(Porto: Aproged - Associação dos Professores de Geometria e de Desenho, 2019)
We have shown that there is a link between the geometry of the CA II-nM’s with bases n∈{3, 4, 5} and that of the convex antiprisms with the same bases. An integer number (K) of CA II-nM’s fragments, can be used to form a ...
Free vibration analysis of curved spatial Bernoulli-Euler beam with circular cross section using isogeometric approach
(2019)
In this paper the linear free vibration analysis of an arbitrarily curved spatial Bernoulli – Euler beam with circular cross section using isogeometric approach has been presented. In order to carry out free vibration ...
Izogeometrijski pristup u analizi slobodnih vibracija prostornih Bernuli – Ojlerovih grednih nosača
(2019)
У овом раду приказана је анализа слободних вибрација просторних гредних Бернули – Ојлерових носача произвољног облика применом изогеометријског приступа. Изогеометријским приступом геометрија носача се описује на исти начин ...
Positive impact of 3D CAD models employment in descriptive geometry education
(Gliwice: PTGiGI, 2019)
Classical Descriptive Geometry (DG) course used 2D drawings for 3D spatial elements representation. Computer graphic introduced simulation of a 3D geometric environment in contemporary DG teaching. Research aim is the ...
Experimental investigation of compressed stainless steel angle columns
(International Colloquium on Stability and Ductility of Steel Structures, 2019)
This paper presents the experimental programme of an extensive research project that deals with analysing the behaviour of compressed stainless steel columns with equal angle sections. The research focuses on different ...
Examination of the experience of biomorphic form materialized in urban design model
(Springer Verlag, 2019)
This research provides initial examination of the impact that biomorphic forms, implemented in public space as urban design model, has on its potential users. The methods, which were included in this research, was modeling ...
Quality control plan for road bridges – Overview of COST Action TU1406 WG3 final report
(IABSE Symposium, Guimaraes 2019: Towards a Resilient Built Environment Risk and Asset Management - Report, 2019, 2019)
The main objective of the COST Action TU1406 is to develop a guideline for the establishment of Quality Control plans for roadway bridges. The guideline is based on conclusions of Working groups 1 and 2 of the Action and ...
Prototype of the 3D Cadastral System Based on a NoSQL Database and a JavaScript Visualization Application
(2019)
3D cadastral systems are more complex than traditional cadastral systems and they require more complex technical solutions and innovative use of developing technologies. Regarding data integrity and data consistency, 3D ...
