    Weighted Oscillator Strengths And Lifetimes For The S Xiv Spectrum

    No full text
    The weighted oscillator strengths gf and the lifetimes for S XIV presented in this work have been calculated in a multiconfigurational Hartree-Fock relativistic approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure in order to improve the adjustment to experimental energy levels. This method produces gf values that are in better agreement with observed line intensities and lifetime values closer to the experimentally determined ones. In this work we presented all the experimentally known electric dipole S XIV spectral lines. © 2009 Springer Science+Business Media, Inc.763447451Fawcett, B.C., Hayes, R.W., (1973) Phys.

    The weighted oscillator strengths (gf) and the lifetimes for Si IV presented in this work were carried out in a multiconfiguration Hartree-Fock relativistic (HFR) approach. In this calculation, the electrostatic parameters were optimized by a least-squares procedure, in order to improve the adjustment to experimental energy levels. This method produces gf-values that are in better agreement with intensity observations and lifetime values that are closer to the experimenta ones.

    A Compact And Flexible C++ Framework To Support Modular Development Of Hierarchical Dynamic Systems Simulators (wip) Embrapa Agricultural Informatics

    No full text
    This paper describes the core of an object-oriented simulation framework (SF), implemented in C++, to support hierarchical dynamic systems simulators development. The simulation framework (SF) presented herein arose from the need for a tool to facilitate and standardize the development of process-based simulation models in research projects at Embrapa (Brazilian Agricultural Research Corporation). This SF targeted modularity and simplicity of code to facilitate model development by multidisciplinary research teams and implementation by high turnover groups of student trainees. Model components, typically developed by teams of experts in specific processes, can be developed independently and later connected, sequentially or aggregated in a hierarchical way. The SF allows compiling simulators as libraries and provides a general interface to allow simulations to be carried out by client applications, e.g. graphical user interfaces, databases, statistical or mathematical packages. In contrast to other existing frameworks, this SF does not store the trajectories of the variables but allows the client application to get the values of the outputs along the simulation through the use of callbacks. The client application can store the variables trajectories in the most convenient way for its specific purpose. The SF supports continuous, discrete-event and hybrid simulations. An example application is provided.464237242Bergez, J.E., Chabrier, P., Gary, C., Jeuffroy, M.H., Makowski, D., Quesnel, G., Ramat, E., Garcia, F., An open platform to build, evaluate and simulate integrated models of farming and agroecosystems (2013) Environmental Modelling & Software, 39, pp. 39-49Bolte, J., Object-oriented programming for decision systems (1998) Agricultural Systems Modeling and Simulation, pp. 629-650. , Peart, R.
