Transparent PMMA/silica nanocomposites containing silica nanoparticles coating under supercritical conditions
(Progress in Organic Coatings, 2013)
This work reports the preparation of PMMA/silica nanocomposites with high optical transparency and enhanced mechanical properties using a melt compounding method. The surface of SiO2 particles was modified with a ...
Circle in Space—Space in Circle: A Study of Ratio between Open Space and Built-Up Area in Historical Circular Objects
(MDPI, 2021)
Many cities nowadays explore different circular designs as new sustainable city concepts in different urban aspects. The new trend, as part of the adaptation for climate change, is a strategy of increasing the number of ...
Pseudosymmetry of General Collinear Planes
(Dresden: Technische Universität Dresden; International Society for Geometry and Graphics (ISGG), 2008)
The paper is considering a special case of general collinear planes, which creates an
illusion of axial symmetry of the corresponding figures, for the specially chosen method of mapping. Comparing the original figure in ...
Generating a Type of Concave Cupolae of Fourth Sort
(Timişoara: Editura Politehnica, 2013)
The paper discusses the generation of a specific group of polyhedra, Concave Cupolae of Fourth Sort (CC IV) with regular polygonal bases, using constructive and analytical procedures. Beside determination of the parameters ...
Biomimetic approach to parametric flower modeling
(19th International Conference on Geometry and Graphics 2021 ISGG, São Paulo, Brazil, 2021)
A sustainable design based on biomimicry can still fulfill the functional needs of humans and be
visually satisfying by representing man's connection to nature. Biomorphic means life, living forms,
it’s often associated ...
Bohmian-Based Approach to Gauss-Maxwell Beams
(MDPI, 2020)
Usual Gaussian beams are particular scalar solutions to the paraxial Helmholtz equation,
which neglect the vector nature of light. In order to overcome this inconvenience, Simon et al.
(J. Opt. Soc. Am. A 1986, 3, 536–540) ...
Improvement recommendations for railway infrastructure maintenance
(EDP Sciences, 2020)
Based on the railway network performance, Infrastructure Manager is obligated to define the Maintenance plan for railway infrastructure, which contains corresponding values for intervention limits and alert limits. This ...
Fatigue damage detection in composite rods using fiber optic intensity based sensors
(Trans Tech Publications Ltd, 2004)
An application of the embedded intensity based fiber optic sensors (FOS) for fatigue damage detection in cantilevered composite rods is presented. During the fatigue test with constant amplitude of oscillations, the ...
Should particle trajectories comply with the transverse momentum distribution?
(European Physical Journal-Special Topics, 2008)
The momentum distributions associated with both the wave function of a particle behind a grating and the corresponding Bohmian trajectories are investigated and compared. Near the grating, it is observed that the former ...
Energy distribution of X-rays reflected from a half space in double collision approximation
(Elsevier Ltd, 2006)
The results obtained in a Monte Carlo simulation of X-ray reflection from water show that for energies up to 20 keV, single and double reflected photons absolutely dominate. Analyzing in detail geometry of the collisions ...
