  • 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 ...

  • (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. ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
