With the maturing of laser technologies, laser processing is presenting itself as an attractive alternative to traditional machining techniques due to its free-form, non-contact nature. It is believed to be especially relevant for hard and brittle materials, such as sapphire. However, due to the complex nature of the physical processes involved, especially for transparent materials, optimization of...
In this paper, we explore user-specific QoS requirements and associated schedulers that are very critical in optimizing the spectral allocation for wireless systems. Two user-specific QoS aware schedulers are proposed that considers the user-specific QoS requirements in the allocation of resources. Depending upon whether improving the MOS (Mean Opinion Score) or both the system capacity and the MOS...
With the increase of service time of aircraft, the damage in aircraft composite material components may be caused. A uniplanar multi-electrode capacitive sensor is used for detecting the damage in aircraft composite material. In order to improve the sensitivity of the sensor, the optimization for the structure parameters of the sensor with 8 electrodes is carried out. The optimization indexes of the...
BackgroundMinimally invasive surgery (MIS) has many advantages compared with open surgery, but there are still many drawbacks in performing MIS. Using robotic technologies, many problems caused by human restrictions, such as fatigue and low precision, can be solved. In this paper, a novel mechanism for a MIS robot is proposed.
MethodsKinematics analysis was carried out and singularity and isotropy...
Offshore wind farm has been one of the most effective ways to wind energy exploitation, and many new technical and economic problems are brought with development of large offshore wind farms. Electric distribution system plays an important role in reliable operation of large offshore wind farm and holds considerable proportion in total investment, so that optimization of the system is one of the key...
This paper first presents development tendency and the importance of internal electric connection system of offshore wind farms. As internal electric connection system plays an important role in reliable operation of wind farm and holds considerable proportion in total investment, optimization of the system is one of the key problems in development of offshore wind farms. Based on analysis of main...
