In order to overcome the limitation of traditional maintenance support and adapt to the development of the maintenance support for armored equipment, this paper puts forward the idea of constructing a maintenance support system for armored equipment based on PHM technology, emphatically analyses the key technology of the system, such as data acquisition and sensor technology, data mining and information...
The design scheme of variable structure control for discrete-time systems is considered. Due to the shortcoming of discrete exponential reaching law which can not push the system state approach to zero but induce oscillation, a new discrete reaching law is presented to improve the reaching process of discrete exponential reaching law via using saturation function to replace sign function. The discrete-time...
The Scale Invariant Feature Transform, SIFT, is invariant to image translation, scaling, rotation, and is partially invariant to illumination changes. But, the time of features extraction and matching is huge, and the number of features is much larger then that is needed. To reduce the number of features generated by SIFT as well as their extraction and matching time, a modified approach based sampling...
