In network code setting, a constant dimension code is a set of k-dimensional subspaces of F nq . If F_q n is a nondegenerated symlectic vector space with bilinear form f, an isotropic subspace U of F n q is a subspace that for all x, y ∈ U, f(x, y) = 0. We introduce isotropic subspace codes simply as a set of isotropic subspaces and show how the isotropic property use in decoding process, then...

In this paper, we present a three-dimensional Poisson equation solver for the electrostatic potential of a charged beam with large longitudinal to transverse aspect ratio in a straight and a bent conducting pipe with open-end boundary conditions. In this solver, we have used a Hermite–Gaussian series to represent the longitudinal spatial dependence of the charge density and the electric potenti...

Modern chemical legislation requires measuring the bioconcentration factor (BCF) of large numbers of chemicals in fish. The BCF must be corrected for growth dilution, because fish growth rates vary between laboratories. Two hypotheses were tested: (1) that BCFs of multiple chemicals can be measured simultaneously in one experiment, and (2) that internal benchmarking using a conservative test su...

On the occasion of the thirty-first anniversary of the publication of The Multinational Corporation and the Law of Uneven Development by Hymer, the paper seeks to assess the relevance of Hymer’s prediction to our current understanding of the multinational company (MNC) and its role in world economic development. It argues that the largely ethnocentric type of MNC portrayed by Hymer is descripti...

Professional development is critical in providing constant updates on EFL teachers’ teaching practice. This mixed methods study was conducted to explore the effects of participation in action research on EFL teachers’ practice. Eighteen junior school English teachers participated in this study. Teacher participants conducted their action research during a five-month period. The quantitative pha...
