Closeness centrality is a basic centrality measure that characterizes how centrally located a node is, within a network, based on its distances to all other nodes. In this paper, we address the distributed computation of two variants of this measure, known as classic closeness and exponential closeness, which differ in how the distances are taken into account. For each variant, we construct continuous-...
Chinese enterprises have been conducting low-end processing for foreign brands. In recent years, they want to get rid of this high-pay low-income pattern and develop towards the high-end of the value chain. Most of them are transforming to service-focused enterprises that aim to provide customers with customized service. In service-focused enterprises, the human asset ¨C like industry experts, technology...
In this paper, we propose an effective method for detecting linear up-sampling in images. Our method includes three parts. First, we present an algorithm, Resampling Matrix Construction, that automatically derives the resampling matrix for any given resampling factor of fraction. Second, we show an algorithm, Zeroing Mask Derivation, that constructs a zeroing mask for the resampling produced by the...
On the inefficient panel adjustment of large reflector antenna, a method for determination of panel adjustment magnitude according to far field pattern is presented. Using the method of Physical Optics (PO), the relationship between the far field value and the node displacement is derived. Then the panel adjustment vector is related to far field pattern with linear equations. Singular value decomposition...
