A digital calibration technique to linearize capacitor mismatch, residue amplifier gain, and nonlinearity in a two-step ADC based on the split-ADC technique [1] is presented. Although multiple publications have been reported before on the split-calibration of pipelined ADC's, none of them is comprehensive, meaning capacitor mismatch, residue gain, and linearity are never treated in one work at the...
In this paper, a simulation model of an electromagnetic rail launcher system based on PSpice software is applied, in consideration of multi-physics factors, such as current skin effect, contact pressure and contact resistance on the contact surface of the armature and the barrel, velocity skin effect, friction drag and temperature coefficient of resistivity. Analyses were made on the effects of various...
A distributed-energy-store (DES) railgun was designed, which excels at higher efficiency in comparison with a breech-fed one. Such a structure was first proposed by Marshall and had been testified to lessen the energy remaining in the rails and reduce the rails' resistive loses. The pulsed-power supply consists of eight modules of capacitor banks, which can provide a maximum energy of 200 kJ. A 4-m-long...
Based on research of the phase plane division control method, according to the structure of wheel loader steer by wire system and its work condition, the fuzzy five states control system specially designed for wheel loader steer by wire system is introduced in this paper. To verify its performance, the controller was simulated in MATLAB/SIMULINK based on the model of wheel loader steer by wire system...
Stacking schedule has become more and more important for container terminal operation, especially for automatic marine container terminals. It is studied by minimize the total work done by transportation, and lower the average stack height. The stacking slot is optimized in two kinds of operation mechanisms, cranes and railcars. The simulation result obtained by iterative method shows the difference...
The quantum cryptography is an emerging technology, which uses quantum mechanics properties of micro-particles to encode information. In the theory and practice, it has been proved to be totally safe. Because of quantum channel being susceptible to be interfered by noise, error correction in quantum communication is facing a big problem today. This article will focus on cyclic redundancy check (CRC)...
In this paper, we analyze the survivability of Mobile Ad Hoc Network systemically and give a detailed description of the survivability issues related to the MANET. We begin with analyzing the requirements of survivability of ad hoc network, and then classify the impacts that affect survivability into three categories: dynamic topology, faults and attacks. The impacts of these factors are analyzed...
