According to the different branches of city’s intersections and the traffic flow at different times, the program of intelligent traffic light controller based on VHDL is given and simulated by Quartus¿ by using hierarchical design thought. The simulation results show that the intelligent traffic light controller can realize the transition of… (More)
BACKGROUND Akebia saponin D (ASD) exerts various pharmacological activities but with poor oral bioavailability. In this study, a self-nanoemulsifying drug delivery system (SNEDDS) based on the drug-phospholipid complex technique was developed to improve the oral absorption of ASD. METHODS ASD-phospholipid complex (APC) was prepared using a… (More)
The key technique for the design of a frequency divider is to find a function between the input and output. In general, the design process and circuit of a frequency divider is complicated, modification and transplantation for it is difficult. A creative design method of CAIFD (Controllable Arbitrary Integer Frequency Divider) is presented in this paper,… (More)
This paper features the novel three stage CBIR system using different orders of Zernike moments. In the first stage, segmentation is done using various image processing techniques. In the second stage, two sets of features each containing 32 Zernike moments and one more set containing 62 Zernike moments with different orders are extracted from the images.… (More)
A detecting system aiming to Light Addressable Potentiometric Sensors is proposed. By means of this system not only the sensitive signal data can been measured and stored real time, but also the system configuration can be set and query via the friendly User Interface. History data can be reviewed conveniently using database technology.
We isolated eight novel polymorphic microsatellite loci from Pteridium aquilinum. These loci were characterized in 30 individuals, one from Bolivia, two from Peru, one from the USA, one from Japan, and 25 from Northeast China to Southwest China. The number of alleles per locus ranged from two to seven. The observed heterozygosity (H(O) ) ranged from 0.000… (More)
