The detailed analysis of the standards of roof crush resistance was presented in this paper. Based on the comparison of GB 26134-2010, FMVSS 216 and FMVSS 216a, come to the conclusion about the trend of roof crush resistance standard-stronger crush resistance and less injury potential in rollover accidents. In this paper the test machine, test process and requirements were described in detail. It's...
From the analysis of belt conveyor power design method based on the DIN22101 standard, the main factors affecting the energy consumption of the system were educed. Meanwhile, an experiment rig of a belt conveyor and parameters measurement devices were designed and built, and the principles for measuring these parameters were analyzed. After that, the energy consumption laws of the system were investigated...
The calculable resistors can be used to calculate AC-DC difference dependence of frequency. Usually the resistance wires are chosen high resistivity material and as thin as possible to avoid skin effect and so on. However, this kind of wires often induce much temperature drift from DC base value, when current flows through the wires. The performance of the calculable resistors is limited by the loading...
Differential power analysis (DPA) has been shown to be a highly effective and easy to mount side-channel attack. One effective method of increasing DPA resistance is to use three-phase dual-rail pre-charge logic (TDPL), but this type of logic is vulnerable to manipulation of the clock generation/distribution hardware. If an attacker can slow down the clock, separate the evaluate phase from the discharge...
This paper discusses the current practice for selecting high voltage insulators and the changes needed to accommodate Load Resistance Factor Design. Conversion of insulator rated strength, defined according to ANSI C29 Standards, to damage limit strength to provide the service limit resistance required by LRFD is discussed. Specific values of service limit resistance and strength factors for different...
The next generation of wireless communication is a ubiquitous radio system concept, providing wireless access from short-range to wide-area, with one single reconfigurable and adaptive system for all envisaged radio environments. This paper presents the design approach of RCO (reconfigurable concurrent oscillator) that simultaneously generates two or more signals of different frequencies that eliminate...
