Multiple antenna signals in wireless communication system form into a kind of multiple dimension array signal from the view of time, frequency and space factors which can be modelled and processed by tensor analysis method. This paper focuses on the application of PARAFAC-based tensor decomposition method in solving the problem of signal blind recovery in MIMO-OFDM wireless communication system. The...
The composite was prepared by injection molding of waste residue from paper mill and recycle polyethylene. In the composite, maleic anhydride grafted polyethylene (MAPE) was used as coupling agent. Influence of different weigh ratio of waste residue and MAPE on mechanical properties of the composites was studied. The test result was as follows: the weigh ratio of waste residue and MAPE coupling agent...
The catalytic gasification properties and reaction kinetics of rice husk (RH) were studied by thermogravimetric analysis (TGA). The homogeneous model (HM) and shrinking core model (SCM) were used to simulate the gasification behaviors. The results indicated that magnesia and ferric oxide had obvious effects on the pyrolysis and gasification properties. They could increase the pyrolysis rate and gasification...
Supercritical CO2 extraction was employed to separate simulated and real bio-oil. Effects of adsorbents on enrichment were investigated for a simulated bio-oil, which is composed of acetic acid (AC), propanoic acid (PA), furfural (FR), acetylacetone (AA) and 2-methoxyphenol (MP). Extraction of spiked bio-oil shows adsorbents are able to influence extraction efficiency and selectivity. Appropriate...
Monitoring and control of time-sensitive products can be facilitated by the application of radio frequency identification (RFID) technology. This paper describes impact on the SCM chain and the profit under dynamic price using RFID technology by mathematic model. The profit using RFID technology is more than the profit no using the technology.
