In recent years, an increasing number of high voltage cable joints have been installed in large cities, such as Guangzhou and Shenzhen, in the area of China Southern Power Grid. Several failures of 110kV and 220kV silicone rubber pre-molded cable joints happened, which resulted in great power loss and big risk to the power system safe operation. In order to understand the mechanism of electrical tree...
Although many wearable sensors have been developed or commercialized for gait analysis, ambulatory force sensors and motion sensors were rarely integrated to implement complete human dynamics analysis. Three-dimensional (3D) lower limb kinematic and kinetic analysis based on ambulatory measurements is introduced in this paper. We developed a wireless sensor system composed of a mobile force plate...
In clinical applications, the quantitative analysis of gait variability using kinematic and kinetic characterizations can be helpful to medical doctors in monitoring patient recovery status. A high-speed camera system and a stationary force plate can only accurately measure complete ground reaction force (GRF) and body orientations during a few steps, but data on successive gait measurements including...
The autopilot design of a side jet and aero-fin blending control air-to-air missile is discussed in this paper and a Model Reference Variable Sliding Structure (MRVSS) method is presented. The side jets are in the discontinuous on-off pulse forms which are different from the conventional continuous side jets. The control parameters are sought though Genetic Algorithm (GA). Further, a novel adaptive...
Accurate identification of lesion borders is an important task in the analysis of dermoscopy images since the extraction of skin lesion borders provides important cues for accurate diagnosis. Snakes have been used for segmenting a variety of medical imagery including dermoscopy, however, due to the compromise of internal and external energy forces they can lead to under- or over-segmentation problems...
A stationary force plate can only accurately measure complete ground reaction force (GRF) during no more than one stride, but the data of a successively measured multi-axial GRF in different environments is desired not only for researchers on gait analysis but also for clinical doctors. A wearable force plate system was developed by integrating small triaxial force sensors and 3D inertial sensors...
