A high-accuracy optical vector analysis (OVA) based on dual-polarization MZM (DPol-MZM) and polarization control is proposed and demonstrated via simulation. By applying the DPol-MZM and adjusting the polarization control module, a linearly polarized optical single-sideband (OSSB) signal with various phase shifts between the swept sidebands and the carrier is achieved. Two measurements are impleme...Show More
Network packets record communication behaviors and details, which is important for security audits, attack detection, and forensic analysis. For the effectiveness and timeliness of security analysis, it is necessary to fully store network packets and build an efficient packet index. However, the existing packet indexing algorithms based on the radix tree ignore the distribution characteristics of ...Show More
The paper presents a traffic signal control method using a layer-structured fuzzy neural network (FNN) for learning rules of fuzzy logic control system. The FNN has advantages of both fuzzy expert system (fuzzy reasoning) and artificial neural network (self-study). The system is not needed to build the model of traffic flow for signal control approach at an intersection, it can be successfully tra...Show More
