In the present study, we used 27 precipitation average monthly data from synoptic, climatologic, rain-guage and evaporative stations located in Zayandeh-Rud river basin for the period of 1970-2014. Before interpolating, the missing data in the time series of each station was reconstructed by the normal ratio method. Also, for the data quality control, the Dickey-Fuller and Shapiro-Wilk tests we...
In this paper, we introduce Inverse topology in a BL-algebra A and prove the set of all minimal prime filters of A, namely Min(A) with the Inverse topology is a compact space, Hausdorff, T0 and T1-Space. Then, we show that Zariski topology on Min(A) is finer than the Inverse topology on Min(A). Then, we investigate what conditions may result in the equivalence of these two topologies. Finally,...
In this paper, the inverse kinematics and inverse dynamics analysis of a parallel mechanism is presented. The mechanism consists of three fixed-length legs each supported by a three-wheeled mobile robot. The three legs support a platform, which acts as the end-effector of the mechanism. Two different designs are evaluated: one with ball joints at the top ends of the legs and revolute joints at ...
Background & Objectives : Leishmaniasis is a disease of the skin caused by a variety of protozoa. Leishmaniasis can be seen in any geographic region. This study investigated the role of climate on the prevalence of cutaneous leishmaniasis in the city of Sabzevar between 2003 and 2009. Methods : Daily meteorological data (minimum, maximum and mean temperature, sunshine hours, precipitation, ...
The “potato kugel” theorem of Aharonov, Schiffer, and Zalcman, which concerns an inverse property harmonic functions, is extended to the settings modified Helmholtz equation that describe nuclear forces acoustic waves respectively.
A connected signed graph Ġ, where all blocks of it are positive cliques or negative (of possibly varying sizes), is called a block graph. Let A, N and D̃ be adjacency, net Laplacian distance matrices graph, respectively. In this paper the formulas for determinant were given firstly. Then inverse (resp. Moore-Penrose inverse) obtained if nonsingular singular), which sum Laplacian-like matrix at m...
The BFGS update and the DFP update perhaps are respectively the most successful Hessian and inverse Hessian approximations for unconstrained minimization problems This paper describes a geometric meaning of these updates understood from the Wedderburn rank one reduction formula
برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
