Recently, the southern central coast of Vietnam has suffered from severe coastal erosion. In order to cope with these problems, physical understanding of long-term wave characteristics is essentially important as basic engineering information. Accordingly, this study examines the longterm variation of reanalyzed wind waves in duration 1900-2010 at this area based on the ERA-20C reanalysis data set in order to clarify the long-term tendency as well as the seasonal characteristics of wave properties.

We introduce a stochastic grammatical channel model for machine translation, that synthesizes several desirable characteristics of both statistical and grammatical machine translation. As with the pure statistical translation model described by Wu (1996) (in which a bracketing transduction grammar models the channel), alternative hypotheses compete probabilistically, exhaustive search of the translation hypothesis space can be performed in polynomial time, and robustness heuristics arise naturally from a language-independent inversiontransduction model. ...

The purpose of this paper is to give a generalization of Mason’s theorem by the Wronskian technique over fields of characteristic 0. Keywords: The Wronskian technicque, Marson’s theorem. 1. Introduction Let F be a fixed algebraically closed field of characteristic 0. Let f (z) be a polynomial non - constants which coefficients in F and let n(1/f ) be the number of distinct zeros of f . Then we have the following. Marson’s theorem. ([2]). Let a(z), b(z), c(z) be relatively prime polynomials in F and not all constants such that a + b = c. Then max {deg(a), deg(b),...

Note immediately one difference between linear equations and polynomial equations: theorems for linear equations don’t depend on which field k you are working over, 1 but those for polynomial equations depend on whether or not k is algebraically closed and (to a lesser extent) whether k has characteristic zero. Since I intend to emphasize the geometry in this course, we will work over algebraically closed fields for the major part of the course.

ONE PARAMETER FAMILY OF LINEAR DIFFERENCE EQUATIONS AND THE STABILITY PROBLEM FOR THE NUMERICAL SOLUTION OF ODEs L. ACETO, R. PANDOLFI, AND D. TRIGIANTE Received 21 July 2004; Accepted 4 October 2004 The study of the stability properties of numerical methods leads to considering linear difference equations depending on a complex parameter q. Essentially, the associated characteristic polynomial must have constant type for q ∈ C− . Usually such request is proved with the help of computers.
