any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
sunflower (helictnthur annuus l. cvs mehr shafagh) seedlings were grown in nutrient solutions containing 20.5 to 70.4 mm nacl and 0 as the control. the effects of salinity on developmental changes occurring in the shoot apices of plants were studied. at 20.5 mm naci concentration, the leaf emergence rate and plastochron index of shafagh increased significantly, but this phenomenon was not obser...
Several methods to identify plants have been proposed by several researchers. Commonly, the methods did not capture color information, because color was not recognized as an important aspect to the identification. In this research, shape and vein, color, and texture features were incorporated to classify a leaf. In this case, a neural network called Probabilistic Neural network (PNN) was used a...
cucumbers grown under open air conditions, encounters chilling damages, during cold seasons. plastic tunnels provide suitable heat environment for growing cucumber. the objective of this research was to evaluate cucumber phonological stages and leaf area expansion within three different plastic tunnel microclimates to moderate air temperature and air humidity. three microclimates including 1. c...
growing demands and requires of high data rate systems cause significant increase of high frequency systems for wideband communication applications. as mixers are one of the main blocks of each receivers and its performance has great impact on receiver’s performance; in this thesis, a new solution for ku-band (12-18 ghz) mixer design in tsmc 0.18 µm is presented. this mixer has high linearity a...
Rice is one of the most important food crops, thus identification of definitive traits on the yield can be used in breeding programs. In order to determine the best suitable morphological markers for selection of superior genotypes, seeds of 15 rice genotypes including 5 varieties (namely: Binam, Dasht, Neda, Mashhad Domsiah and IR62871-175-1-10) and their 10 F1 hybrids of corresponding variate...
Sunflower (Helictnthur annuus L. cvs Mehr Shafagh) seedlings were grown in nutrient solutions containing 20.5 to 70.4 mM NaCl and 0 as the control. The effects of salinity on developmental changes occurring in the shoot apices of plants were studied. At 20.5 mM NaCI concentration, the leaf emergence rate and plastochron index of Shafagh increased significantly, but this phenomenon was not o...
what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...
Image textures are groups of metrics computed to classify the captured texture of images. It reveals the information about the spatial orientation of color or gray level intensities in the images or specific regions of the images. The image texture classification of plant leaves is considered in this paper because of the extinction risk of various plants. An efficient plant leaf identification ...
different researchers in different parts of the world have investigated the strategies used to translate written works ranging from novels to classroom assignments. however, by the significant increase in the number of postgraduate students in iran in the last few years, a very common kind of translation in iran includes translating abstracts of master’s theses. in this work, the researcher hav...
