  • DOSIMETRIC EVALUATION OF A NEWLY DEVELOPED RADIOCHROMIC FILM FOR RADIATION PROCESSING 

    AKHAVAN, A.؛ SOHRABPOUR, M.؛ SHARIFZADEH, M. (Springer, 2008-12-01)
    In order to improve the performance of a newly developed radiochromic film, GIC-79, somedosimetric characteristics of this film have been studied based on relevant standard practice. The presentstudy describes some parameters ...

  • BOUND STATE ENERGY OF DELTA-FUNCTION POTENTIAL: A NEW REGULARIZATION SCHEME 

    JAHAN, A.؛ JAFARI, M. (Springer, 2008-12-01)
    In this letter we have proposed a new regularization scheme to deal with the divergent integralsoccurring in the quantum mechanical problem of calculating the bound state energy of the delta-functionpotential in two and ...

  • IONOSPHERIC ABSORPTION OF HF RADIO WAVE IN VERTICAL PROPAGATION 

    UNAL, I.؛ OZCAN, O.؛ CANYILMAZ, M. (Springer, 2008-12-01)
    In this study, absorption of high frequency radio waves in the ionospheric plasma have beeninvestigated. The wave equation was obtained in terms of ionospheric parameters. The numerical values ofthe absorption have been ...

  • ON EINSTEIN (α,β )-METRICS 

    REZAEI, B.؛ RAZAVI, A.؛ SADEGHZADEH, N. (Springer, 2008-12-01)
    – In this paper we consider some (α ,β ) -metrics such as generalized Kropina, Matsumoto and F (α β )2α = + metrics, and obtain necessary and sufficient conditions for them to be Einstein metrics when βis a constant Killing ...

  • VELOCITIES OF DUAL HOMOTHETIC EXPONENTIAL MOTIONS IN D3* 

    ASIL, V. (Springer, 2008-12-01)
    In this paper the concept of Homothetic Dual Exponential Motions in D3 is discussed and theirvelocities obtained. Due to the way in which the matter is presented, the paper gives some formula and factsabout dual exponential ...

  • PROJECTIVELY RELATED EINSTEIN FINSLER SPACES 

    SADEGH-ZADEH, N.؛ RAZAVI, A.؛ REZAEI, B. (Springer, 2008-12-01)
    The main objective of this paper is to find the necessary and sufficient condition of a given Finslermetric to be Einstein in order to classify the Einstein Finsler metrics on a compact manifold. The consideredEinstein ...

  • ON R-QUADRATIC FINSLER METRICS 

    Najafi, Behzad؛ BIDABAD, B.؛ TAYEBI, A. (Springer, 2008-12-01)
    We prove that every R-quadratic metric of scalar flag curvature with a dimension greater than twois of constant flag curvature. Then we show that generalized Douglas-Weyl metrics contain R-quadraticmetrics as a special ...

  • (Aσ )Δ -DOUBLE SEQUENCE SPACES VIA ORLICZ FUNCTIONS AND DOUBLE STATISTICAL CONVERGENCE 

    Savas, Ekrem؛ PATTERSON, R. F. (Springer, 2008-12-01)
    The aim of this paper is to introduce and study a new concept of strong double Δ ( A ) σ -convergence sequences with respect to an Orlicz function, and some properties of the resulting sequencespaces were also examined. ...

  • AUTOCORRELATION FOR A CLASS OF POLYNOMIALS WITH COEFFICIENTS DEFINED ON T 

    Taghavi, Mohsen (Springer, 2008-12-01)
    In this work we deal with the coefficients of A (e it ) 2 , where A is in a class of polynomialshaving Unimodular coefficients. We first present a technique that calculates lower bounds for particularautocorrelations and ...

  • PREDICTION ALGORITHM FOR TORQUE RIPPLE REDUCTION IN DTC-BASED DRIVES 

    KABOLI, Sh؛ ZOLGHADRI, M. R.؛ ESKANDARI, P.؛ ROYE, D. (Springer, 2008-12-01)
    In direct torque control, the selection of an applied voltage vector is based on the measuredparameters at the beginning of the sampling period. The delay between the measurement and the application of the voltage vector ...

  • LINEAR PROGRAMMING PROBLEM WITH INTERVAL COEFFICIENTS AND AN INTERPRETATION FOR ITS CONSTRAINTS 

    ABBASI MOLAI, A.؛ KHORRAM, E. (Springer, 2008-12-01)
    In this paper, we introduce a Satisfaction Function (SF) to compare interval values on the basis ofTseng and Klein's idea. The SF estimates the degree to which arithmetic comparisons between two intervalvalues are satisfied. ...
