Gene therapies have been applied to the treatment of cardiovascular disease, but their use is limited by the need to deliver them to the right target. We have employed targeted contrast ultrasound-mediated gene transfection (TCUMGT) via ultrasound-targeted microbubble destruction (UTMD) to transfer therapeutic genes to specific anatomic and pathological targets. Phospholipid microbubbles (MBs) with...
Money number recognition refers to the money of the currency, the currency and authenticity recognition. Money number recognition system is the kernel module of self-service system, and the major applied range is cash-related equipments. In this paper we design a kind of money number recognition system. The quick positioning of money number is achieved based on gray value accumulation. The edge line...
The serial port communication system is introduced, in which frequency conversion is used to control electrical motor on the tractor-trailer lateral stability experimental platform. The method of MSCOMM of VB active X and the communication protocol of VFD-M transducer are explained. The serial communication program between industrial control machine and frequency transducer is given based on VB 6...
Vibration signals are the important information for system failures. Forecasting the trend of vibration signals is an important content of condition monitoring and fault diagnosis. A novel time series analysis is presented to analyze and forecast nonlinear random vibration signals. Mathematical models are established to describe vibration signals. First, the non-stationary vibration signals acquired...
CMOS active pixel sensor (APS) is currently the most popular image sensor architecture. In this paper, a CMOS active pixel image sensor with analog-to-digital converter (ADC) is presented. The driving controller of the image sensor is implemented on CPLD chip in the real-time mode, and performed successfully. The detailed design of the image sensor driving circuit is provided. Some codes with VHDL...
In this paper, the subject of discussion is the uncertainties of Ant Colony Algorithm (ACA). In order to find application and popularize the ACA, we try to find some disciplinarians which can eliminate the impact of uncertainties in our algorithm and find the best assembled of the parameters by a series of experiments. Results show that our works had great effects in practicality.
A novel time series analysis is presented to analyze and forecast nonlinear random vibration signals. Mathematical models are established to describe vibration signals. First, the non-stationary vibration signals acquired in the field are transformed to stationary time series. Second, the time series models are constructed from the selected reference signals, and nonlinear least square method is used...
Gesture segmentation is the first and the most critical step in sign language recognition. In this paper a method of gesture segmentation from the video image sequence based on monocular vision is presented by skin color and motion cues. Firstly, determine the background images and capture the gesture images with a sampling interval of 10 frames. Then with the difference method, the movement region...
