  • DESIGN AND CONSTRUCTION OF A HIGH PRECISION TAC 

    ESFANDI, F.؛ SHAHRIARI, M.؛ ABBASI DAVANI, F.؛ SHARGHI IDO, A. (Springer, 2009-06-01)
    TAC (Time to Amplitude Convertor) is one of the most important time measurement instrumentswhich has great significance in many fields of science, especially radiation physics. A TAC unit has beendesigned based on the ...

  • ALMOST CONVERGENCE THROUGH THE GENERALIZED DE LA VALLÉE-POUSSIN MEAN 

    Mursaleen, Mohammad؛ JARRAH, A. M.؛ MOHIUDDINE, S. A. (Springer, 2009-06-01)
    Lorentz characterized the almost convergence through the concept of uniform convergence of de laVallée-Poussin mean. In this paper, we generalize the notion of almost convergence by using the concept ofinvariant mean and ...

  • THE INVOLUTE-EVOLUTE OFFSETS OF RULED SURFACES 

    KASAP, E.؛ YÜCE, SALİM؛ KURUOGLU, N. (Springer, 2009-06-01)
    In this study, a generalization of the theory of involute-evolute curves is presented for ruledsurfaces based on line geometry. Using lines instead of points, two ruled surfaces which are offset in the senseof involute-evolute ...

  • N-ARY POLYGROUPS 

    GHADIRI, M.؛ WAPHARE, B. N. (Springer, 2009-06-01)
    Polygroups are multivalued systems that satisfy group like axioms. In this paper the class of n-arypolygroups is introduced. The concepts of n-ary normal subpolygroups and strong homomorphisms of n-arypolygroups are adopted. ...

  • ON A SPECIAL CLASS OF FINSLER METRICS 

    TAYEBI, A.؛ Peyghan, E (Springer, 2009-06-01)
    In this paper, we study projective Randers change and C-conformal change of P-reduciblemetrics. Then we show that every P-reducible generalized Landsberg metric of dimension n  2 must be aLandsberg metric. This implies ...

  • A CLASS OF LIFT METRICS ON FINSLER MANIFOLDS 

    PEYGHAN, E.؛ Tayebi, Akbar (Springer, 2009-06-01)
    In this paper, we are going to study the g-natural metrics on the tangent bundle of Finslermanifolds. We concentrate on the complex and Kählerian and Hermitian structures associated with Finslermanifolds via g-natural ...

  • 1-TYPE AND BIHARMONIC FRENET CURVES IN LORENTZIAN 3-SPACE 

    KOCAYIGIT, H.؛ HACISALIHOGLU, H. H. (Springer, 2009-06-01)
    1-type and biharmonic curves by using Laplace operator in Lorentzian 3-space arestudied and some theorems and characterizations are given for these curves.

  • INEQUALITIES FOR MEROMORPHICALLY P-VALENT FUNCTIONS 

    EBADIAN, A.؛ NAJAFZADEH, SH. (Springer, 2009-06-01)
    The aim of this paper is to prove some inequalities for p-valent meromorphic functions in thepunctured unit disk Δ* and find important corollaries.
