Abstract
One method of reducing truncation error in numerical prediction is the use of more accurate finite-difference approximations. A relatively simple barotropic model, similar to the one currently in use by the Fleet Numerical Weather Facility (FNWF), Monterey, California, is employed as a basic program in testing several higher order finitedifferencing schemes. Forecasts were computed to 24 and 4# hours with modifications of the basic model, and comparisons were made with the analyses at verifying time. It is the intent of this study to determine the effects of some higher order finite-difference approximations in this numerical prediction model. The author expresses his appreciation to Professor George J. Haltiner for his suggestions, guidance, and patience. Appreciation is also expressed to the personnel of FNWF for providing data and programming assistance.

    Boundary conditions and stability of a perfectly matched layer for the elastic wave equation in first order form 

    Duru, K.; Kozdon, JE; Kreiss, G. (2015);
    In computations, it is now common to surround artificial boundaries of a computational domain with a perfectly matched layer (PML) of finite thickness in order to prevent artificially reflected waves from contaminating a ...

    Design method of numerical function generators based on polynomial approximation for FPGA implementation 

    Nagayama, Shinobu; Sasao, Tsutomu; Butler, Jon T. (2007-08);
    This paper focuses on numerical function generators (NFGs) based on k-th order polynomial approximations. We show that increasing the polynomial order k reduces signicantly the NFG's memory size. However, larger k requires ...

    A Diffusion Approximation for a Repairman Problem with two Types of Repair. 

    Gaver, D.P.; Lehoczky, J.P. (Monterey, California: Naval Postgraduate School, 1977-01); NPS-55-77-3
    The backlog at repair shops confronted by two types of failures is modeled by stochastic diffusion approximations. The quality of the approximations is assessed by numerical methods.
