In this paper, a control-oriented model for compressor mass flow rate is proposed. For this purpose, the compressor is approximated as an adiabatic nozzle with compressible fluid, driven by external work from the compressor wheel. The external work input is modeled using Euler's turbomachinery equations, with the main flow losses estimated via a simple slip factor model. All other flow losses, that...
Rising concern for thermal stress and tight energy constraints have forced designers to consider power as a design criterion from early design phase. Despite many advances in highlevel power estimation techniques, there is a lack of generic power estimation capabilities in prominent high-level design flows. In this paper we propose power modeling and estimation techniques during Architecture Description...
In this paper, the Compressed Sensing (CS) based channel estimation scheme for the sparse multipath channel in OFDM system is considered. The CS based multipath delay channel model is investigated by using only a small amount of pilots to get the measurement matrix and the orthogonal matching pursuit (OMP) is adopted to reconstruct the channel impulse response. In order to overcome the drawback of...
Price level is the core indicator of market-economic operation and the relationship between the price and the business cycle is one of the most important problems which have intently drawn the attention of the theorists. This paper analyses the relationship between the price and China's business cycle with the co-integration test, Granger causality test, establishing the VAR model, proceeding Impulse...
