  • DESIGN AND CONSTRUCTION OF AN ACCURATE TIMING SINGLE CHANNEL ANALYZER 

    EZZATPANAH LATIFI, A.؛ ABBASI DAVANI, F.؛ SHAHRIARI, M.؛ SHARGHI IDO, A. (Springer, 2009-09-01)
    In this paper we discuss an approach to the design and construction of an accurate timing singlechannel analyzer (TSCA) for the timing of pulses over a wide dynamic range. A brief overview of the timingmethods and uncertainty ...

  • ANALYSIS AND OPTIMIZATION OF A FISSION CHAMBER DETECTOR USING MCNP4C AND SRIM MONTE CARLO CODES 

    HADAD, K.؛ HASHEMI, M. (Springer, 2009-09-01)
    In this study, a general theoretical model to foresee and calculate the current-voltagecharacteristics in a plateau zone and the associated efficiency of the neutron detector (sensitivity) is presented. This study is to ...

  • STUDY OF NEUTRON YIELD FOR THE 241Am9Be SOURCE 

    KAKAVAND, T.؛ HAJI-SHAFEIEHA, M.؛ GHAFOURIAN, H. (Springer, 2009-09-01)
    Beryllium chemical combination has a considerable effect on the design and fabrication of the241Am9Be neutron source. In this investigation the beryllium combinations were studied as a generator ofneutrons with various ...

  • COMMON FIXED POINTS OF TWO NONEXPANSIVE MAPPINGS BY A NEW ONE-STEP ITERATION PROCESS 

    KHAN, S. H.؛ ABBAS, M.؛ KHAN, A. R. (Springer, 2009-09-01)
    We introduce a new one-step iteration process to approximate common fixed points of twononexpansive mappings in Banach spaces and prove weak convergence of the iterative sequence using (i)Opial's condition and (ii) Kadec-Klee ...

  • A GENERALIZED SUMMABILITY FACTOR THEOREM FOR ABSOLUTE SUMMABILITY AND QUASI   POWER INCREASING SEQUENCES 

    SAVAS, E. (Springer, 2009-09-01)
    The object of this paper is to establish a summability factor theorem for summabilityA, , k  1 k  where A is the lower triangular matrix with non-negative entries satisfying certain conditions.

  • FINSLER METRICS WITH SPECIAL LANDSBERG CURVATURE 

    Tayebi, Akbar؛ PEYGHAN, E. (Springer, 2009-09-01)
    In this paper, we study a class of Finsler metrics which contains the class of P-reducible andgeneral relatively isotropic Landsberg metrics, as special cases. We prove that on a compact Finsler manifold,this class of ...

  • ESTIMATION OF GALAXY AGE BY MODIFIED MEYER AND SHRAMM NUCLEOSYNTHESIS MODEL 

    M, Eskandari؛ BAHADORAN, M. (Springer, 2009-09-01)
    The independent model used by Meyer and Schramm (here after M&S) for determining the age ofelements (chemical evolution) is extended. Using new and extended definitions and including parametersignored by M&S, the galactic ...

  • WEIGHTED STATISTICAL CONVERGENCE 

    Karakaya, Vatan؛ CHISHTI, T. A. (Springer, 2009-09-01)
    In this paper, the notion of N, pn - summability to generalize the concept of statisticalconvergence is used. We call this new method weighted statistically convergence. We also establish itsrelationship with statistical ...
