When Alf‘ven effect is peresent in magnetohydrodynamics one is naturally lead to consider conformal field theories, which have logarithmic terms in their correlation functions. We discuss the implications of such logarithmic terms and find a unique conformal field theory with centeral charge c = − 7 , within the border of the minimal series, which satisfies all the constraints. The energy espec...

We discuss the implications of such logarithmic terms and nd a unique conformal eld theory with centeral charge c = ? 209 7 , within the border of the minimal series, which satisses all the constraints.

Article history: Received June 26, 2012 Received in Revised form August, 12, 2012 Accepted 15 September 2012 Available online September 17 2012 One of the primary concerns with data envelopment analysis arises when the number of inputs and outputs increases. In such a case, required computations will become time consuming and there is a concern on developing some hybrid methods to increase the ...

In northern parts of Iran such as the Alborz Mountain belt, frequent landslides occur due to a combination of climate and geologic conditions with high tectonic activities. This results in millions of dollars of financial damages annually excluding casualties and unrecoverable resources. This paper evaluates the landslide susceptible areas in Central Alborz using the probabilistic frequency rat...

BACKGROUND Unlike developed countries, data from the developing world regarding motor developmental disorders is scarce. OBJECTIVES In the present study, we used the Infant Neurological International Battery (Infanib) test to determine the prevalence of motor impairment in 4-18 month-old infants in Alborz province, Iran, in 2010. PATIENTS AND METHODS This study was a descriptive-analytic st...

Investigation of mineralization and fluid inclusions the Lapeh-Zanak copper deposit, Central Alborz zone, Iran

Alborz is a user assisted reverse engineering tool designed for analyzing and recovering the architecture of a software system in the form of cohesive modules and subsystems. The tool’s operation is based on techniques from the area of data mining, pattern matching, and clustering (Figure 1).
