Bound-continuum intersubband transition based optical nonlinearities in semiconductor quantum wells
(Solid State Phenomena, 1998)
The possibility is explored of obtaining resonantly enhanced nonlinear optical susceptibilities in semiconductor quantum wells with two bound states and the resonant state in continuum as the third state. This would ...
Intersubband resonant third harmonic generation in asymmetric semiconductor quantum wells
(Solid State Phenomena, 1998)
Possibilities for the systematic optimization of step-graded ternary alloys based quantum wells, in respect to third order nonlinear susceptibility ar resonance, are discussed. The use of this method is exemplified on the ...
Transposing an Octogonal Cupola of Second Sort Into a Bionic Polyspherical Form
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
In the paper there is presented a method of transposing a polyhedral structure, composed of two
regular polygons: octagon and hexadecagon as the bases, and the envelope formed of equilateral triangular strip, which is ...

Geometric approach to the revitalization process of the medieval Serbian monasteries
(Vilnius Gediminas Technical University, 2015)
Among the standard approaches concerning cultural heritage preservation, the architectural point of view deserves particular attention. The special place in medieval Serbian history of architecture belongs to the world ...
Comparing Tablets (touchscreen devices) and PCs in Preschool Education: Testing Spatial Relationship Using Geometric Symbols of Traffic Signs
(International Engineering and Technology Institute (IETI), 2018)
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 ...
Solid Modeling and Motion Study of Chronometer Detent Escapement Mechanism
(Iasi: "Gheorghe Asachi" Technical University of Iasi, 2011)
Theory of clock, watch and chronometer escapements is important
and interesting part of theory of mechanisms and kinematics. Despite the fact that chronometer escapements are invented in past times, from the viewpoint of ...
Generating Curves of Higher Order Using the Generalisation of Hügelschäffer’ Egg Curve construction
(Timişoara: Editura Politehnica, 2013)
The starting constructions is the well known ellipse construction using the concentric circles c1 and c2. By eccentricity of the center C2 for some value w, and for the preserved center of the transformation in the center ...
An analytical approach based on Green's function to thermal response factors for composite planar structure with experimental validation
(Elsevier Masson SAS, 2019)
The unsteady heat conduction in composite planar structure, with arbitrary number of layers, using analytical approach based on Green's Functions (GF) is analyzed. The analytical solution for spatial and temporal temperature ...
