in this work the performance of a wavelength division multiple access (wdma) system with direct detection receiver is investigated. for this purpose, the probability of error in a wdma network with ook modulation considering crosstalk, isi, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. the system performance in presence of pin...
Background: Photo-damaged skin is characterized not only by wrinkles and creases but also by epidermal and dermal atrophy, rough skin texture, irregular pigmentation, talengiectasis , laxity and enlarged pores. There is growing interest in the development of noninvasive methods to treat photo-damaged skin. Intense Pulsed Light (IPL), a non-coherent, broadband, pulsed light source is effective i...
Optogalavanic technique has been used widely in laser spectroscopy. In this paper we have presented the results of an experimental three- step photo- excitation of Gd atom, using optogalvanic technique. Three tunable dye laser pulses were applied to excite the Gd atom in a three-step photo – excitation process. The optogalvanic signal was used to monitor the laser wavelength and efficiency of...
In recent years, a reversal of the global economic framework has been taking place: from linear model, there gradual transition to circular model where by-products agri-food industry are taken and transformed into value products (upcycling) rather than being disposed of. Olive tree pruning represents an important biomass currently used for combustion; however, leaf part olive is rich in phenoli...
Background: The Cutometer MPA 580® (Courage and Khazaka, Germany) is a well-established instrument for the accurate reproducible measurement of biomechanical properties skin. purpose this study was to assess effect 4 formulations containing 2.5% 5.0% α-lipoic acid ascorbic palmitate or butylhydroxytoluene on skin elasticity firmness equivalence between alternative parameters (Q0, Q1 Q3) traditi...
The problems of photo aesthetic and photo quality are similar, but not exactly the same. In photo aesthetic assessment, we seek photos that looks beautiful to people. The aesthetic score of a photo can be affected by the photo’s color tone, composition, layout, and etc. In photo quality assessment, we seek photos that are in high quality. The quality score of a photo can be affected by shake, b...
gender usually plays a significant role in the works of photographers andcauses men and women to take different photographs. nowadays, photographsand photography have a crucial and pivotal status in societies. the majority of theevents and accidents unfolding in various parts of the world are communicatedto the people via newspapers, magazines, internet and television, and undoubtedly,photograp...
In vitro tensile bond strengths of Photo Clearfil Bright (PB) and Clearfil Photo Posterior (CP) with Clearfil Photo Bond to human enamel and dentin were determined by a truncated cone bond test. Parameters tested were: four substrates (etched enamel; unetched dentin, D1; dentin conditioned with 10% polyacrylic acid, D2; and dentin etched with phosphoric acid, D3); two techniques (bonding agent ...
The purpose of this paper is examines the domestic consumer behavior to income changes, floor coverings price (calculated income elasticity, price elasticity and cross-elasticity), handmade carpets and of carpet by machinery. The results of the models using OLS method in the 1984-2010 shows that Both handmade carpets and carpet by...
In this study, through the elasticity approach, we tried to evaluate the effects of cash subsidy on poverty reduction. In this regard, after the theoretical arguments about the poverty elasticity to income, Gini Coefficient, and price using the data related to the expenses and incomes of the 14701 urban households from 1389 to 1390, the quantitative value of these elasticity was measured and fi...
