چکیده: این پژوهش با عنوان بررسی نقش جامعه ی شبکه ای به روی هویت اجتماعی جوانان شهر اصفهان، در مرحله اول، به شناخت پیامدهای جامعه ی شبکه ای برروی مقوله هویت اجتماعی ومولفه های آن به صورت کلان اقدام شدو در مرحله بعدی به بررسی فرضیه های ارائه شده در طول تحقیق، و درک وجود پیامدهای این پدیده بر روی ابعاد مختلف هویت اجتماعی پرداختیم. در این پژوهش از 2 روش پیمایشی وروش اسناد ومدارک علمی استفاده ده ا...
the proliferation of information and communications technology (ict) along with the incremental growth in the use of cloud services, enterprise network and data center technologies in recent years, have caused unprecedented expansion of computer networks. however, the existing network architecture was not well designed to meet the requirements of today's needs. one of the most important pr...
background: the aim of this study was to survey the iranian parasitology researchers’ performance, and analyse and visualize the scientific outputs of their co-authorship network. methods: this study was conducted using scientometric method and social network analysis (sna). the data extracted from the web of science (wos) databases in july 10th 2014. totally, 1048documents of all types in rese...
background: co-authorship is one of the most tangible forms of research collaboration. a co-authorship network is a social network in which the authors through participation in one or more publication through an indirect path have linked to each other. the present research using the social network analysis studied co-authorship network of 681 articles published in journal of research in medical...
the present study is an attempt towards remodeling cost, revenue and profit relationship within the network process. the previous models of data envelopment analysis (dea) have been too general in their scope and focused on the input and the output within a black box system, therefore they have not been able to measure various phases simultaneously within a network system. by using these models...
today, scouring is one of the important topics in the river and coastal engineering so that the most destruction in the bridges is occurred due to this phenomenon. whereas the bridges are assumed as the most important connecting structures in the communications roads in the country and their importance is doubled while floodwater, thus exact design and maintenance thereof is very crucial. f...
برای اینکه یک ارتباط تلفنی ساده بین مبدا و مقصد برقرار شود نیاز به تجهیزاتی از قبیل گوشی تلفن مشترک a ، کابل جهت ارتباط با مرکز سوئیچینگ ، گوشی تلفن مشترک b ، اگر هر دو مشترک a و b در یک ناحیه نباشند در اینصورت نیاز به تجهیزات transmission که در مخابرات به قسمت pcm مشهور است . حال در نظر بگیرید مشترک a بخواهد با مشترک b تماس بگیرد چه کسی مشترک b را خبر می کند یا وقتی مشترک b گوشی را برمی دارد چ...
drought is random and nonlinear phenomenon and using linear stochastic models, nonlinear artificial neural network and hybrid models is advantaged for drought forecasting. this paper presents the performances of autoregressive integrated moving average (arima), direct multi-step neural network (dmsnn), recursive multi-step neural network (rmsnn), hybrid stochastic neural network of directive ap...
background and objectives: while social network analysis has left a remarkable practical impact in the healthcare field, the potential implication of this methodology in the primary health domain is poorly researched. hence, this study aimed to explore the use and usefulness social network analysis in the context of primary health care. methods: the health volunteers of imam ali health center i...
the instrumental use of social networks has become a central tenet of international health policy and advocacy since the millennium project. in asking, ‘how to facilitate social contagion?’, karl blanchet of the london school of hygiene and tropical medicine therefore reflects not only on the recent success, but also hints to growing challenges; the tactics of partnerships, alliances and platfo...
