Among translation issues, poetry translation is the most problematic area challenging both translators and authorities in the field of translation studies. Translation of poetry as a yet unanalyzed ‘black box’ (Francis 2006) has been a much debated issue since olden times, with many pros and cons and dichotomist reasoning as to its possibility or impossibility. This is due to the high cultural prestige of poetry which requires time, effort and ingenuity to translate traditional rhyme, rhythm structures and the figurative language involved. In the present study, a Persian piece of poetry by the contemporary Iranian poet, Musavi Garmaroodi, A. (1984) and its English translation by Vahid, D. H. (2006) will be focused upon and descriptively analyzed at both linguistic and extra linguistic levels. 8 Towards a Practical Model for Translation Analysis and Assessment of Poetic Discourse The aim is to identify the formative elements of versified discourse in the source and target texts (ST/TT) and to arrive at a tentative model of translation analysis which can serve as a measure for translation assessment of poetic genre.
Optimal Strain Gauge Placement in Instrumented Wheelset for Measuring Wheel-Rail Contact Forces
Vahid Reza Bagheri,Parisa Hosseini Tehrani,Davood Younesian 한국정밀공학회 2017 International Journal of Precision Engineering and Vol.18 No.11
Concurrent measurement of the wheel-rail contact forces is always a crucial factor in design of safe railway vehicles. Commonly, instrumented wheelset has been developed towards this goal. A novel technique for precise design of the instrumented wheelset is presented in this paper. Influences of different factors such as the wheel rotation, the temperature or the centrifugal force are eliminated by cancelation of the higher harmonics. The accuracy of estimated forces is dependent on the placement of gauges on the instrumented wheelset. A solution procedure in terms of mean square error is implemented to determine the optimal radial locations of the strain gauge to achieve the most precise force measurement. Validation of the proposed method through numerical simulation is also presented. We show that the effectiveness and robustness of the technique are preserved even in the presence of noise in strain signal.
Maps preserving Jordan and $\ast$-Jordan triple product on operator $\ast$-algebras
Vahid Darvish,Mojtaba Nouri,Mehran Razeghi,Ali Taghavi 대한수학회 2019 대한수학회보 Vol.56 No.2
Let $\mathcal{A}$ and $\mathcal{B}$ be two operator $\ast$-rings such that $\mathcal{A}$ is prime. In this paper, we show that if the map $\Phi:\mathcal{A}\to\mathcal{B}$ is bijective and preserves Jordan or $\ast$-Jordan triple product, then it is additive. Moreover, if $\Phi$ preserves Jordan triple product, we prove the multiplicativity or anti-multiplicativity of $\Phi$. Finally, we show that if $\mathcal{A}$ and $\mathcal{B}$ are two prime operator $\ast$-algebras, $\Psi:\mathcal{A}\to\mathcal{B}$ is bijective and preserves $\ast$-Jordan triple product, then $\Psi$ is a $\mathbb{C}$-linear or conjugate $\mathbb{C}$-linear $\ast$-isomorphism.
Direct frequency domain analysis of concrete arch dams based on FE-(FE-HE)-BE technique
Vahid Lotfi 한국계산역학회 2004 Computers and Concrete, An International Journal Vol.1 No.3
A FE-(FE-HE)-BE procedure is presented for dynamic analysis of concrete arch dams. In this technique, dam body is discretized by solid finite elements, while the reservoir domain is considered by a combination of fluid finite elements and a three-dimensional fluid hyper-element. Furthermore, foundation rock domain is handled by three- dimensional boundary element formulation. Based on thismethod, a previously developed program is modified, and the response of Morrow Point arch dam is studied for various conditions. Moreover, the effects of canyon shape on response of dam, is also discussed

This paper deals with free vibration analysis of bidirectional functionally graded annular platesresting on a two-parameter elastic foundation. The formulations are based on the three-dimensional elasticitytheory. This study presents a novel 2-D six-parameter power-law distribution for ceramic volume fraction of2-D functionally graded materials that gives designers a powerful tool for flexible designing of structuresunder multi-functional requirements. Various material profiles along the thickness and in the in-planedirections are illustrated by using the 2-D power-law distribution. The effective material properties at a pointare determined in terms of the local volume fractions and the material properties by the Mori-Tanakascheme. The 2-D differential quadrature method as an efficient and accurate numerical tool is used todiscretize the governing equations and to implement the boundary conditions. The fast rate of convergenceof the method is shown and the results are compared against existing results in literature. Some new resultsfor natural frequencies of the plates are prepared, which include the effects of elastic coefficients offoundation, boundary conditions, material and geometrical parameters. The interesting results indicate that agraded ceramic volume fraction in two directions has a higher capability to reduce the natural frequencythan conventional 1-D functionally graded materials.
Effects of forming media on hydrodynamic deep drawing
Vahid Modanloo,Abdolhamid Gorji,Mohammad Bakhshi-Jooybari 대한기계학회 2016 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.30 No.5
Apart from the punch and the die, a pressurized fluid (water or oil) is used in hydroforming. The presence of such pressure media is the main difference between hydroforming and conventional deep drawing. No comprehensive study has yet been conducted on the effect of forming media on the formation of cylindrical cups via hydrodynamic deep drawing assisted by radial pressure. This study investigated the formation of such cups through Finite element (FE) simulation and experiments. First, the process was modeled numerically using ABAQUS FE software. After simulation, copper and St14 sheets were formed with water and oil as the forming media. The effect of these forming media on thickness distribution and maximum punch force was investigated. By examining the thickness distribution curve of the hydroformed cup, a close agreement was found between experimental and numerical results. Using oil as the forming media reduced thinning at the corner radius zone of the punch and increased the maximum punch force. Changing the forming media does not significantly influence the maximum thickening at the cup wall region.

3-D Vibration analysis of FG-MWCNTs/Phenolic sandwich sectorial plates
Vahid Tahouneh 국제구조공학회 2018 Steel and Composite Structures, An International J Vol.26 No.5
In this study, based on the three-dimensional theory of elasticity, free vibration characteristics of sandwich sectorial plates with multiwalled carbon nanotube-(MWCNT)-reinforced composite core are considered. Modified Halpin-Tsai equation is used to evaluate the Young's modulus of the MWCNT/epoxy composite samples by the incorporation of an orientation as well as an exponential shape factor in the equation. The exponential shape factor modifies the Halpin-Tsai equation from expressing a straight line to a nonlinear one in the MWCNTs wt% range considered. In this paper, free vibration of thick functionally graded sandwich annular sectorial plates with simply supported radial edges and different circular edge conditions including simply supported-clamped, clamped-clamped, and free-clamped is investigated. A semi-analytical approach composed of twodimensional differential quadrature method and series solution are adopted to solve the equations of motion. The material properties change continuously through the core thickness of the plate, which can vary according to a power-law, exponentially, or any other formulations in this direction. This study serves as a benchmark for assessing the validity of numerical methods or two-dimensional theories used to analysis of laminated sectorial plates.
