شبکه داده نام گذاری شده (ndn) یکی از مهم ترین معماری های شبکه اطلاعات محور می باشد.مهاجم با بهره گیری از ماشین های درون شبکه می تواند با ارسال سیل آسای درخواست ها از حداکثر زمان انقضای درون این جدول استفاده کرده و حافظه جدول را به ته کشیده و منجر به حذف درخواست های مشتریان قانونی شود.در این پایان نامه روش traceback-filter برای شناسایی حمله و کاهش اثر ترافیک های جعلی پیشنهاد شده است که سعی در شن...

In the recent decades, water scarcity has become a major challenge for many reasons, especially the inadequate use of water resources. The mineral processing plant is among the most important water-consuming industries. Filtration, as one of the important processes in water recovery, is a process in which the solid-suspended particles are removed from the liquid. In the present work, the effect...

in this paper, a novel decision based median (dbm) filter for enhancing mr images has been proposed. the method is based on eliminating impulse noise from mr images. a median-based method to remove impulse noise from digital mr images has been developed. each pixel is leveled from black to white like gray-level. the method is adjusted in order to decide whether the median operation can be appli...

the harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. this paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. the objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
