Global production network has become the main competitive force on the micro level in the process of globalization, which is monopolized by transnational corporations. After the transfer of manufactures from developed countries to developing countries, global transfer turns to service industry, especially the transfer of knowledge intensive services such as financial services, professional serv...

Let A be a function algebra on a locally compact Hausdorff space. A linear isometry T : A −→ A is said to be of codimension 1 if the range of T has codimension 1 in A. In this paper, we provide and study a classification of codimension 1 linear isometries on function algebras in general and on Douglas algebras in particular.

A Canadian physician-engineer who had difficulty finding suitable work in Canada is now employed by an American company that is helping develop the medical systems that will serve astronauts. Dr. Douglas Hamilton thinks research in space medicine will have applications on earth.

An editorial is presented to the article public message Stay Safe, Home has gained global currency for pandemic Topics include according Mary Douglas, home realization of specific ideas, a kind space that serves as both memory machine;and essays in section grapple with myriad meanings

In this paper, we propose an extended mixed finite element method for elliptic interface problems. By adding some stabilization terms, present a approximation form based on Brezzi-Douglas-Marini space and the piecewise constant function space, show that discrete inf-sup is independent of how intersects triangulation. Furthermore, derive optimal convergence holds location relative to mesh. Final...

We consider bijective maps ϕ on the full operator algebra B ( H ) of an infinite dimensional Hilbert space with property that, for every A , X ∈ is Douglas solution equation = if and only Y . prove that those are implemented by a unitary or anti-unitary map U i.e., ⁎

In this paper we study spherically symmetric metrics on a space in $\mathbb{R}^n$ with scalar and constant flag curvature also obtain families of type metrics. Many explicit examples are provided for Douglas curvature. Furthermore, new projectively flat Finsler given. We provide family which not type.

The classic Douglas-Peucker line-simplification algorithm is recognized as the one that delivers the best perceptual representations of the original lines. It may, however, produce simplified polyline that is not topologically equivalent to the original one consisting of all vertex samples. On the basis of properties of the polyline hulls, Saalfeld devised a simple rule for detecting topologica...
