Many diverse application areas are experiencing an explosive increase in the availability of data to analysis, including the medical and biological sciences. Based on the emergency medical database, this research has tried to mine the association between the reason of calling ambulance service and the medical history of patients. The acute conditions, which make people call the ambulance service,...
The satellite data positioning is to calculate the longitude and latitude of instant scanning surface from satellite, traditional location methods is done by the satellite location at the observation time, satellite attitude and scanning angle. But satellite position and attitude often can't be obtained or the precision can't meet the demand, consequently it is difficult to finish positioning. In...
The ability of economic data analysis is very important to information major students in economic and economic universities. However, mastering the skill of economic data analysis is not easy to them. The design and construction of a teaching model based on schema theory in economic data analysis curriculum is described, and then it is applied to information major students. The teaching result shows...
The existing algorithm to reduce peak-to-average power ratio (PAPR) about orthogonal frequency division multiplexing (OFDM) system will be discussed in this paper. A new algorithm is proposed for the particularity of complicated low-voltage power line network communication channel. The algorithm makes original sequence disordered through pseudo-random sequence matrix, and the disordered sequence is...
