Wind tunnel tests are carried out for the Commonwealth Advisory Aeronautical Research Council (CAARC) high-rise building with a scale of 1:400 in exposure categories D. The distribution law extreme pressure coefficients under different conditions is studied. Probability fitting performed on measured area-averaged coefficients. general value (GEV) preferred probability From comparison between an...

Background and Objective: Co-authorship on writing articles is one of the indicators of reliability in scientific articles. Due to the lack of information regarding to the rate of participation of the authors of articles in the ” Iranian Journal of Pathology” this research with the aim of the survey of collaborative coefficients of article authors in this Journal  from 2006 to 2012 was performe...

Kostka numbers and Littlewood-Richardson coefficients play an essential role in the representation theory of the symmetric groups and the special linear groups. There has been a significant amount of interest in their computation ([1], [10], [11], [2], [3]). The issue of their computational complexity has been a question of folklore, but was asked explicitly by E. Rassart [10]. We prove that th...

‎We consider a linear programming problem in a general form and suppose that all coefficients may vary in some prescribed intervals‎. ‎Contrary to classical models‎, ‎where parameters can attain any value from the interval domains independently‎, ‎we study problems with linear dependencies between the parameters‎. ‎We present a class of problems that are easily solved by reduction to the classi...

Reduction can be important to aid quickly attaining the integer least squares (ILS) estimate from noisy data. We present an improved Lenstra-Lenstra-Lovasz (LLL) algorithm with fixed complexity by extending a parallel reduction method for positive definite quadratic forms to lattice vectors. We propose the minimum angle of a reduced basis as an alternative quality measure of orthogonality, whic...

in this article, an effective method to control a power system during emergency conditions is presented. based on fuzzy linear programming (flp), a new technique is developed to solve the load shedding and generation reallocation (lsgr) optimization problem. the objective function consists of terms of load curtailments and deviations in generation schedules. the constraints are power system var...
