Due to the rapid changes and developments caused by technology in the digital age and the growing importance of achieving sustainability for the survival of businesses, the need to create the capabilities needed to innovate in the business model of organizations has become inevitable. This research is trying to provide a model for business model innovation with the aim of sustainability by considering the external factor of digitalization (digital transformation) and the internal factor of dynamic capabilities. The method of this research is mixed so that in the first stage the qualitative method of Meta-Synthesis is used and in the second stage the quantitative method of Interpretive Structural Modeling (ISM) is used. In this research, based on the systematic review of previous researches in scientific databases, 402 related articles were identified and then 46 final articles were selected during the screening process. Based on the thematic analysis, a total of 4 main categories and 14 factors were extracted. In the second stage of the research, an interpretive structural model (ISM) is developed to show the inter‐relationship of different factors and their levels of importance in the food industry.   The 8-level hierarchy model of factors influencing the sustainable business model innovation in the digital age with a dynamic capabilities approach was proposed. Results show that a new component called network value has been added to the traditional business model components. Furthermore, the MICMAC approach has been used to categorise factors according to their driving power and dependence. finally, digital technologies and Sensing were found to be the factors with the highest independence and the highest driving power, and “Economic Sustainability” was identified as the factor with the highest dependence and the least driving power

The most important aspects of image processing are image enhancement. The visual form of an image can be enhanced by using image enhancement techniques for better human interpretation. In this research paper we discuss an   outline and analysis of commonly used image enhancement techniques using finger vein image or personal authentication. Also, experiments are carried out to compare performance of various types of filters for removal of noise from the noisy images through evaluation performance parameter such as mean square error (MSE), peak signal to noise ratio (PSNR) values and structural similarity (SSIM). It was found that application of max filter technique ensures an improved quality of the finger vein image. The mean filter is most advanced in de-noising the images. Mean filter is most efficient in eliminating the salt and pepper noise. From the experiments performed on finger vein image using SDUMLA-HMT database, it is proven that Weiner filters are outstanding for elimination of Gaussian Speckle and Poisson noises and thus, Weiner filter is found to be most appropriate and well-suited for eliminating nearly all types of noise.

Religious tourism is one of the world's most critical current types of tourism, especially in Islamic countries such as Iran, which has a high potential for development and progress in this field. However, the development of this type of tourism in our country is not restricted to only religious cities but includes other cities in Iran. With its religious-pilgrimage functions, Sari city in Mazandaran province provides an appropriate ground for developing religious tourism as one of the main forms of tourism. The present research first conducted a set of observations in the region after studying library documents using the field method. After analyzing data from the observations, research questions were evaluated by organizations, experts, and the local community. The results were quantitatively examined by SWOT analysis. Finally, according to extracted concepts from qualitative and quantitative analysis, a model for the development of religious tourism was obtained based on library and field studies using interviews and then evaluated by experts. Results show that religious places of Sari city aren’t on the list of development priorities. It presents a model for development in this region with more challenges. Therefore, the qualitative and quantitative analysis results of this research imply a very appropriate situation and a high potential for religious tourism, emphasizing Imamzadeh in Sari city.
