Non-orthogonal access in cognitive radio is typically controlled by limiting the interference power caused to the primary network by so-called interference temperatures. For receivers with multiple antennas the definition of a scalar measure for the impact of interference is ambiguous and the generalization of interference temperatures is non-trivial. We propose a cognitive radio concept by imposing constraints, […]

To improve the efficiency of direct solution methods in SPICE-accurate integrated circuit simulations, preconditioned iterative solution techniques have been widely studied in the past decades. However, it is still an extremely challenging task to develop robust yet efficient general-purpose preconditioning methods that can deal with various types of large-scale integrated circuit problems. In this work, […]

A bi-directional isolated Cuk equalizer for the energy bus-based equalization network is presented in this paper. The battery side is isolated from the bus side by two isolated capacitors. A synchronous approach for Cuk equalizer is used to improve equalization efficiency. The equalization efficiency can achieve above 90% in a wide range of equalization power. The operating […]

Residential and commercial buildings consume more than 40% of electrical power and contribute a large percentage of CO2 and SO2. In order to alleviate energy crises and environment deterioration, improving energy efficiency of buildings has become significant and important. This paper considers the storage battery scheduling problem in a networked building microgrid with decentralized solar power and […]
