As a rectangular enclosure with apertures can be represented by a waveguide with its termination short circuited, the shielding effectiveness of the enclosure is calculated by the transmission line model. The voltage along the transmission line is obtained analytically, and the calculated shielding effectiveness fits well to the previous reference. Slots in different shapes are discussed, and multimodes...
This paper proposes a model for analysis of life cycle cost (LCC) of the transmission systems. First, to build the model of LCC of the transmission systems, the whole LCC process of components is divided into five costs, i.e., initial cost, operating cost, maintenance cost, fault cost and disposal cost. Second, during the calculation of the maintenance cost, the grey system theory is employed to predict...
In this paper, the notion of the Generalized canonical manifold is introduced, and the wavelet transform on the topological field manifold is defined. The reconstruction formula of the wavelet transform on the topological field manifold is established.
eXtensible Business Reporting Language (XBRL) is a language for the electronic communication of business and financial data, which can offer more efficiency and improved accuracy to suppliers and users of the data. But heterogeneous XBRL taxonomies hinder the interoperability. This paper first gives structural heterogeneity based on Ontology, then analyzes the structural conflictions between one taxonomy...
M.H. Faroughi introduced the concept of C-Fusion frames. In this paper, we consider the stability on C-Fusion frames for Hilbert spaces. We get some results that are in spirit close to classical results for discrete frames. We also expand the conclusion of the perturbation for a pair of C-Fusion Bessel sequences. Several meaningful results are obtained.
