The renormalization group (RG) method for differential equations is one of the perturbation methods for obtaining solutions which approximate exact solutions for a long time interval. This article shows that, for a differential equation associated with a given vector field on a manifold, a family of approximate solutions obtained by the RG method defines a vector field which is close to the ori...
We combine old ideas about exact renormalization-group-flow (RGF) equations with the Vilkovisky-De Witt (VDW) approach to reparametrization invariant effective actions and arrive at a new, exact, gauge-invariant RGF equation. The price to be paid for such a result is that both the action and the RGF equation depend explicitly upon the base point (in field space) needed for the VDW construction....
It is shown that the renormalization group (RG) method for global analysis can be formulated in the context of the classical theory of envelopes: Several examples from partial differential equations are analyzed. The amplitude equations which are usually derived by the reductive perturbation theory are shown to be naturally derived as the equations describing the envelopes of the local solution...
Graph theory provides a primary tool for analyzing and designing computer communication networks. In the past few decades, Graph theory has been used to study various types of networks, including the Internet, wide Area Networks, Local Area Networks, and networking protocols such as border Gateway Protocol, Open shortest Path Protocol, and Networking Networks. In this paper, we present some key...
Information Subject Gateways are providing access to the necessary quality controlled databases among the vast resources for users of the web and saving them from the confusion and perplexity among the sources on the web. The main objective of this research is creating Iranian Gateway for Scientific, Research, and Technological Information as a valuable source for use by academics and researche...
We analyze the Ising model on a random surface with a boundary magnetic field using matrix model techniques. We are able to exactly calculate the disk amplitude, boundary magnetization and bulk magnetization in the presence of a boundary field. The results of these calculations can be interpreted in terms of renormalization group flow induced by the boundary operator. In the continuum limit thi...
We show that the results for the soft couplings in supersymmetric gauge theories recently derived via the superconformal anomaly are equivalent to results obtained earlier from a consideration of exact RG-invariant trajectories. We give a full proof of these results for a general multi-coupling theory. Moreover, we demonstrate the existence of a distinct finite RG-invariant solution for the sof...
A hybrid Mobile AdHoc Network (MANET) is provided by gateways (GWs), which connect the MANET to the Internet. Hybrid MANETs are vulnerable to more security threats while routing through the gateways. To guarantee secure hence efficient data routing and transmission, In this paper, we propose to design a data aware secure gateway selection technique for hybrid MANET. In our technique, gateway is...
in this paper, new features of satellite configuration, such as ip network based infrastructure and separated signaling and media are considered to propose a variety of satellite configurations in different orbits. because of their different altitude in space such as low earth orbit(leo) and geostationary orbit (geo). a test bed used to test call setup delay in a one space link to process th...
