    Work presented here is a part of a comprehensive study which aimed at calculating the walkability levels of streets. The walkability levels are to be calculated based on five walking needs which have been identified in previous stages. In the work presented here, equations which can predict five walking needs were developed based on independent variables which represent the effect of physical environment

    Analysis of the (N,xN') reactions by quantum molecular dynamics plus statistical decay model

    We propose a model based on quantum molecular dynamics (QMD) incorporated with statistical decay model (SDM) to describe various nuclear reactions in an unified way. In this first part of the work, the basic ingredients of the model are defined and the model is applied systematically to the nucleon(N)-induced reactions. It has been found that our model can give a remarkable agreement in the energy-angle double differential cross sections of (N,xN') type reactions for incident energies from 100 MeV to 3 GeV with a fixed parameter set. An unified description of the major three reaction mechanisms of (N,xN') reactions, i.e. compound, pre-equilibrium and spallation processes, is given with our model

    Towards a More Complete and Accurate Experimental Nuclear Reaction Data Library (EXFOR): International Collaboration Between Nuclear Reaction Data Centres (NRDC)

    The International Network of Nuclear Reaction Data Centres (NRDC) coordinated by the IAEA Nuclear Data Section (NDS) is successfully collaborating in the maintenance and development of the EXFOR library. As the scope of published data expands (e.g., to higher energy, to heavier projectile) to meet the needs from the frontier of sciences and applications, it becomes nowadays a hard and challenging task to maintain both completeness and accuracy of the whole EXFOR library. The paper describes evolution of the library with highlights on recent developments.Comment: 4 pages, 2 figure
