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 ...

A three-level relief chain including a number of suppliers in fixed locations, candidate distribution centers and affected areas at certain points are considered. A mixed integer nonlinear programming model is proposed for open transportation location routing problem by considering split delivery of demand. To solve a realistic problem, foregoing parameters are considered as fuzzy in our propos...

Humanitarian relief logistics is one of the most important elements of a relief operation in disaster management. The present work develops a multi-objective robust stochastic programming approach for disaster relief logistics under uncertainty. In our approach, not only demands but also supplies and the cost of procurement and transportation are considered as the uncertain parameters. Furtherm...

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...

with the eight sassanians reliefs, naghsh-e rustam in marvdasht is a prominent complex safeguarding a complete collection of the sassanian period. seven of these reliefs have been repeatedly the subject of investigations thanks to their relatively better conditions. the fifth relief, however, has not yet been studied due to their damaged status. it depicts the full-face portrait of a sassanid k...

BACKGROUND The aim of this study was to compare patient-perceived relief of ocular itch, nasal symptoms, and eye drop comfort when allergic conjunctivitis was treated with bepotastine besilate 1.5% versus olopatadine hydrochloride 0.2%. METHODS This randomized, observer-masked, single-center, crossover study included 30 patients with ocular itching associated with allergic conjunctivitis acco...

Affect has been shown to influence respiration in people. This article takes this insight and proposes a real-time model to express affect through respiration in virtual humans. Fourteen affective states are explored: excitement, relaxation, focus, pain, relief, boredom, anger, fear, panic, disgust, surprise, startle, sadness and joy. Specific respiratory patterns are described from the literat...

In the present study, the 3-dimensional artistic relief designs on the leather belt used to create CNC tool path and the parameters were investigated in the production of hot pressing molds. The 3-dimensional relief patterns obtained with the help of belt pressure molds consist of marks pressed along the belt with the hot press. These intricate patterns create the varieties in the world of wear...

Transmission gratings that combine a large diffraction angle with a high diffraction efficiency and a low angular and wavelength dispersion could be used to collect sunlight in a light guide. In this paper we compare the diffractive properties of polarization gratings and classical surface-relief gratings and explore their possible use in solar concentrators. It is found that polarization grati...
