strategic environmental assessment can be viewed as a process to integrate the concept ofsustainable development into planning. in this context, sea can be regarded as a method that regulates theplanning process to a state of sustainable development. however, to reach that goal it is necessary to achieve full integration of planning and the sea process.therefore this paper considers the integra...

in the present time, phenomenon like globalization, regionalism and economic integration are the basic issues which bring many positive consequences to the world economy. regionalism and economic integration are one of the ways that developing countries can adopt to collate the globalization process. to acknowledge their own abilities or, to settle the commercial and economic disputes in their ...

We present an overview of intrinsic integration schemes for diierential equations evolving on manifolds, paying particular attention to homogeneous spaces. Various examples of applications are introduced , showing the generality of the methods. Finally we discuss abstract Runge{Kutta methods. We argue that homogeneous spaces are the natural structures for the study and the analysis of these met...

The paper develops a construction for finding fully symmetric integration formulas of arbitrary degree 2k + t in n-space such that the number of evaluation points is O ((2n)k/k t), n ~ . Formulas of degrees 3, 5, 7, 9, are relatively simple and are presented in detail. The method has been tested by obtaining some special formulas of degrees 7, 9 and 1 t but these are not presented here.

(March 5, 1969) In a previous paper, a general theorem was investigated for the s tability of numerical integration methods for the so lution of systems of diffe rentia l equation s. In thi s paper, further theore ms are developed as suffi c ie nt conditions for the instability of nume rica l integration methods. Applying these theore ms , the ins:abiljt.y of known formula s are checked eas ily...

A high-accuracy prescription (quadrature rule) is the set of points Xj and weights Wj such that the error E (n) is a small and rapidly decreasing function of n, the number of mesh points used. Now suppose we want to integrate a function F(X l ,x2'''''Xd) = F(x) over the d-dimensional cube. The direct product technique would be to use the rule (1) d timesi ". n2 "d L L '" L Wj, Wh ... wjdF (Xj" ...
