Complementary-polarizer magnetic tunnel junction (CPMTJ) is a promising device for high-performance nonvolatile memory because of its low critical current and inherently differential structure. In this letter, we present a novel CPMTJ-based STT-MRAM structure with separated reading and writing paths and explore the capability of the proposed structure to achieve disturbance-free READ operations based...
On-load tap changer (OLTC) is the important component of on-load tap changing transformers. It can maintain the stability of voltage by adjusting the tap position without interrupting the load current. Due to the carbonization and oil pollution of conventional OLTC with oil switching, vacuum OLTC with permanent magnetic actuator has been developed. To guarantee the speed and reliability of the OLTC,...
The coupling mechanisms on a commercial mobile phone PCB with different shielding configurations has been investigated with FDTD simulation in this paper. A modified PCB based on the commercial PCB was manufactured for validation purposes prior to the simulation. Good agreement between simulation and measurement was obtained. The coupling performance of the commercial PCB was then reproduced with...
The coupling mechanisms between the active traces and a victim trace with two victim ports on a real phone PCB model was investigated with FDTD simulation in this paper. The studied scenarios include the PCB with a full shielding, perforated shielding and no shielding. Firstly, the coupling performance of the real phone PCB was reproduced with numerical simulations. According to the simulation results,...
This paper transformed the process of Chinese question answering into agent coalition formation first, and then got the solution by using of combination of genetic algorithm and ant colony algorithm. The idea and routine of the algorithm were given. Coding scheme, selecting scheme, crossover operator, mutation operator and so on of genetic algorithm which suitable for Chinese question answering agent...
The major wireless operators are actively migrating their networks from circuit switched networks to all packet (IP) based next generation networks. One of the key issues impeding the migration is the associated cost. Though managing the CAPEX (CAPital EXpenditures) and OPEX (OPerational EXpenditure) has been the focus of the operators, minimizing the cost from the perspective of system design has...
