Being as a significant section of security issues in Wireless Mesh Network (WMN), the research and application about Intrusion Detection System (IDS) in WMN are just getting start. The characters and requirements for IDS in WMN are described and analyzed firstly; Based on the Hierarchical Proxy-based Topology (HPT) structure in Mesh network, an efficient(More)
This study examined the potential deleterious effect of high-dose nitroglycerin (NTG) on cardiac function and cellular injury after ischemia (30 min) and reperfusion (120 min) in isolated perfused rat hearts. Low-dose (0.75 microg/h), medium-dose (3.75 microg/h), high-dose (15 microg/h) NTG or high-dose NTG plus glutathione (GSH, 1 mmol/L) was administrated(More)
Structural engineers may utilize geometric techniques for precise and accurate measurements of discrete points, detailed façade recording, and the productions of engineering drawings and plans. An introduction to laser scanning is given, followed by details of one test on the Natou city wall in Shenzhen, China, one of the important military towns in the(More)
This paper describes a hybrid cascaded inverters, which can be applied to low power energy storage system. The working mode of the circuit and the dead-time effect are analyzed. Base on the traditional control mode, a new way is given to control the auxiliary capacitor voltage. In order to solve the problem that multilevel SPWM method take up to much system(More)
OBJECTIVE To establish an HPLC fingerprint to evaluate the quality of Polygalae Radix, root xylem, and those collected in different growth ages or harvest time. METHOD Separation was performed at 30 °C on a Kromasil C18 column (4.6 mm x 250 mm, 5 μm); the mobile phases was acetonitrile and 0.05% H3PO4 water in the gradient elution; the flow rate was set(More)
Using the 3D electromagnetic particle-in-cell (PIC) code MAFIA, the simulation of the electronic trajectory in electron gun with PPM stack could be carried out. A 3D electron optics model has been built, which includes a electron gun, transit area and a PPM stack. All components of the model are simulated in three dimensions, allowing the ripple and(More)
