To the question that the transmission bandwidth is limited but requires to sign efficiently and safely, a new certificate less blind sign cryption scheme with partial message recovery is proposed in this article based on the exiting certificate less based blind sign cryption scheme and identify-based signature scheme with partial message recovery. This scheme can track KGC dishonest behavior. Adopted...
In this paper, we introduce the concepts of generalized fuzzy ®-ideals and fuzzy ®-ideals of semigroups, and study their related properties by fuzzy points.
Solar-blind metal–semiconductor–metal (MSM) photodetectors (PDs) with Ni/Au semi-transparent interdigitated contact electrodes are fabricated on epi-layer grown by metal-organic chemical vapor deposition on sapphire substrate. The PD exhibits ultra-low dark current in fA range at room temperature (RT) under 20-V bias and a corresponding breakdown voltage higher...
Due to energy limit of sensors, lifetime maximization of wireless sensor network is one of the key problems protocol design. Low Energy Adaptive Clustering Hierarchy (LEACH) is a well known routing protocol in WSN, but its performance decreases sharply with increase of the network scale. To solve this problem, we introduce an improved LEACH routing protocol to balance energy consumption among the...
Death of part of the nodes in wireless sensor network is a key problem to affect lifetime of the whole network. To avoid early death of such nodes, we put forth a children parent scheme implemented with Leach protocol. The children parent scheme allows supplement of nodes when some node runs out of energy due to causes such as hot spot or unbalanced network topology. Experiment results show the scheme...
Digital video segmentation is an active area of research. Generally, the significances of this segmentation mask can be explained as follows: Firstly, the mask can be used for image examining, editing, compression, analysis and understanding. Secondly, the virtual reality system can use the panorama and mask to appear the virtual 3-D environment. So the research of such an efficient video segmentation...
Digital image mosaic is an active area of research. Generally, the significances of this synthetic panorama can be explained as follows: Firstly, increasing the angle of the optics system view. Secondly, the panorama can be used for image examining, editing, analysis and understanding. Thirdly, the virtual reality system can use the panorama to appear the virtual 3-D environment. So the research of...
To solve moving parameters identification problem for deep sea-bed mining robot, estimation model of key parameters is built after the discussion on robot dynamic model and hydraulic system. And a controller based on key parameters estimation model is presented to accomplish the path following task for deep sea-bed mining robot with assumption that the desired path is given. Experiment results on...
