In the last four 'decades, relational database management systems have been used widely to manage structured data in different disciplines. Nowadays, data resources increase rapidly in different forms (including structured, ...

Railway networks are one of the most necessary infrastructures all around the world. Today, to manage these networks, Geographic Information System (GIS) techniques should be used in order to study and analyze the railway ...

A wireless sensor network (WSNs) is a network that consists of a large number of ultra-small autonomous devices which are resource-constrained called sensor nodes. Sensor networks may be deployed for a wide range of ...

Wireless Sensor Networks (WSNs) are used in many applications such as monitoring, target tracking and military applications, etc. A network is comprised of a large number of small, cheap, computational, limited energy ...

Since the last mid-century researchers start investigate in the performance of IIR (interactive information retrieval). Many methods and measures were innovated and used in this field studies. To ensure the replication of ...

This thesis consists of three sections. The first section is reserved for introduction, some basic definitions and declaration of literature about alpha-psi type contractive mappings and related fixed point theorems have ...

With the rapid increase of Arabic users around the world, a need of understanding the preferences of this wide Stratum of society is important. To do so we designed a questionnaire to evaluate three search engines (Google, ...

There are many complex dynamics appearing in nature science and technology one of the most useful approaches to model these phenomena is hybrid dynamical systems hybrid dynamic systems describe the interactions of continuous ...

Digital media are distributed through the internet system in a magnificent manner due to the efficiency and inexpensiveness of such a system. Audio clips and other digital signals are transmitted, shared and used easily. ...

In this thesis, we show that when we applied the Newton's method on the exponential function,f(z)=p(z)eQ(z) where p(z) and Q(z) are polynomials in the complex plane, the attraction basins of roots have finite area when n ...
