the geopolitics of afghanistan after september 11, 2001, and its impact on iranian national security
abstract u.s. attack to afghanistan after 9/11 provided opportunities for us who tried to become the dominant power after collapse of ussr and bipolar world. thinkers like fukuyama believed american liberal democrats thought would be universally accepted without resistances. liberal democracy is the best and final model of governance; in this regard, united state has moral responsibilities for...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...
The time course of acoustic events is a critical element for the recognition of biologically meaningful sounds. Echolocating bats analyze the time intervals between their emitted biosonar pulses and the echoes returning from objects to assess target distance (range). In this study, we have explored the auditory cortex of the mustached bat, Pteronotus parnellii rubiginosus, using pairs of acoust...
This paper takes an economic approach to investigate the role of geographical proximity for organizing new product development (NPD) activities within inter-firm linkages. Product development theory and the resource-based view is discussed from an inter-firm perspective and contrasted to arguments in the literature on geographical economics. The approach in this paper assumes that geographical ...
In the last decade, a number of techniques from the new media practices have contributed to innovate the traditional production of entertainment, through the modularization and the automation of a number of phases. This paper proposes a novel approach to the automatic generation of character animations that draws inspiration from the techniques for the construction of the virtual agents. The pi...
Doing business globally involves very complex and increasingly dynamic processes and demands a high level of flexibility and adaptability from the companies involved. In the automotive sector, the timescale for development of new vehicles has been drastically shortened, while at the same time the number of variants and derivatives has grown. Under these conditions, development processes, involv...
We present soft X-ray results from observations with Chandra (HETGS) of the Seyfert I AGN NGC 4593 and Mrk 509. We discuss the photoionized outflows associated with Seyfert I AGN in terms of their absorption spectral signatures and discuss their kinematics, column density and ionization state. We discuss the link between UV and X-ray absorbers in Mrk 509 (which was simultaneously observed with ...
We have obtained∼ 100 pc resolution CO and ∼ 60 pc resolution Hα observations of the dwarf spiral galaxy NGC 4605. We use them to derive a high resolution rotation curve and study the central density profile of NGC 4605’s dark matter halo. We find that these observations do not agree with the predictions of most high resolution Cold Dark Matter calculations. We investigate two extreme cases: 1)...
The advantages of using parallel processing technology in industrial applications lie in the field of cost reduction and turnaround time improvement. For example in seismic production, the improvement in turnaround time can lead to lower costs and quicker results for clients. Also in product development where computer simulations play a significant role, for instance drug design, aircraft desig...
