According to NLOS(Non-Line-of-Sight) robot's miniaturization and remote control technology requirement, a NLOS mobile robot control system based on embedded system technology, communication technology, imagine processing technology and sensor technology is raised, which puts an ARM9 processing chip S3C2410 as a controller and ARM-LINUX as a real-time operating system. Using H.264 video coding compression...
With the information security issues caused by the abuse of enterprise network resources, the objectives and functions of content auditing system are analyzed. According to the principle of content audit, the two-stage classification mechanism and open software architecture have been proposed to support the renewal and extension of application protocols. The hash algorithm for multi-pattern string...
Content audit analyzes the messages of application layer communication between the peers, and matches the set security policies to ensure legitimate and effective use of network resources. The link management is one of the key issues in designing the content audit system. In order to achieve efficient management of TCP links and the correlation analysis of the same session, the hash list is proposed...
Quality control is a crucial issue in producing velcro, and defects existing in velcro can dramatically downgrade velcro level. Manual inspection can not meet the requirements of production efficiency, so an online feasible inspection method is referred to control the surface quality of the velcro. The original algorithm for the edge detection has been improved, and the flaws are extracted according...
To prevent carbon/carbon (C/C) composites from oxidation at 1873 K, a dense SiC–Si–MoSi 2 coating toughened with SiC whiskers (SiCw) was prepared by a two-step technique. The first step technique is to prepare a porous SiC coating toughened with SiCw by slurry, and the second one is to fill Si and MoSi 2 in the holes of SiC coating by pack cementation. Oxidation test shows that the...
