occurrence of natural disaster inflicts irreparable injuries and symptoms on humans. in such conditions, affected people are waiting for medical services and relief commodities. thus, quick reaction of medical services and relief commodities supply play important roles in improving natural disaster management. in this paper, a multi-objective non-linear credibility-based fuzzy mathematical prog...
We have studied light-induced birefringence (LIB) and surface relief grating (SRG) formation in the series of methylacrylate polymers. The effect of material structure such as length of photochromic side chain, glass transition temperature and molecular structure of azo units on LIB and SRG are studied. The optical formation of self-induced SRG on films of these materials is also presented.
Three-dimensional (3D) microstructures are essential elements in various technological applications, including optical coatings, [ 1 , 2 ] tissue engineering scaffolds, [ 3 ] microfl uidics, [ 4 ] energy storage devices, [ 5 , 6 ] plasmonics, [ 7 ] and photonic crystals. [ 8 , 9 ] While conventional methods, such as photo lithography and electron beam lithography, are costly and ineffective in ...
Abstract In this study, we realize the high-power output of a single-mode 894 nm vertical-cavity surface-emitting laser (VCSEL) at high temperature. The effects dimensional parameters oxide aperture and surface relief on transverse mode threshold gain VCSEL were analyzed. Through collaborative optimization relief, with 8 µm diameter 5 inner can operate temperature 365 K power 2.02 mW side-mode ...
We present a method for synthesizing high reliefs, a sculpting technique that attaches 3D objects onto a 2D surface within a limited depth range. The main challenges are the preservation of distinct scene parts by preserving depth discontinuities, the fine details of the shape, and the overall continuity of the scene. Bas relief depth compression methods such as gradient compression and depth r...
