the image of a brand is the first word or image that is evoked in the mind of costumers immediately after hearing the brand name. the purpose of paying attention to the brand image is to ensure the proper mentality of consumers toward the brand. the components such as suitability, services, brand, variety, quality, and atmosphere form the brand image. the relationship between the brand image an...

mental health in adolescents is influenced by several factors. body image is one of the factors in predicting mental health. moreover, it affects social communication and creates the social anxiety. the present study is cross-sectional and correlational. the statistical population is the guidance and high school students in shiraz in 2013-2014 that 180 students include 101 girls and 79 boys wer...

introduction in ct imaging, metallic implants inside the tissues cause metal artifact that reduce the quality of image for diagnosis. in order to reduce the effect of this artifact, a new method with more appropriate results has been presented in this research work. materials and methods the presented method comprised of following steps: a) image enhancement and metal areas extraction, b) sinog...

The edges of an image define the image boundary. When the image is noisy, it does not become easy to identify the edges. Therefore, a method requests to be developed that can identify edges clearly in a noisy image. Many methods have been proposed earlier using filters, transforms and wavelets with Ant colony optimization (ACO) that detect edges. We here used ACO for edge detection of noisy ima...

introduction: an efficient method of tomographic imaging in nuclear medicine is positron emission tomography (pet). compared to spect, pet has the advantages of higher levels of sensitivity, spatial resolution and more accurate quantification. however, high noise levels in the image limit its diagnostic utility. noise removal in nuclear medicine is traditionally based on fourier decomposition o...

background: brain tissue segmentation for delineation of 3d anatomical structures from magnetic resonance (mr) images can be used for neuro-degenerative disorders, characterizing morphological differences between subjects based on volumetric analysis of gray matter (gm), white matter (wm) and cerebrospinal fluid (csf), but only if the obtained segmentation results are correct. due to image arti...

The present paper is aimed at introducing a new algorithm for image encryption using chaotic tent maps and the desired key image. This algorithm consists of two parts, the first of which works in the frequency domain and the second, in the time domain. In the frequency domain, a desired key image is used, and a random number is generated, using the chaotic tent map, in order to change the phase...

consumer purchasing decisions relating to foreign products are influenced by economic, psychological and sociological factors. this study attempts to relate such rarely studied variables as animosity and ethnocentrism to concepts taken from consumer behavior which are brand image and purchase intention. consequently, this study attempts to provide insights into how brand image, consumer ethnoce...
