Flexural vibration mode piezoelectric ceramic transducers can be used in many application fields because of their ability to develop large displacement at low levels of electrical excitation, or conversely, to generate high output from sources of low mechanical impedance. Many flexural transducers are very thin, and their behavior can be analyzed and predicted accurately by the current theory based...
Optimization of network planning is important for improving the QoS of the RFID networks before deployment. This paper proposes an efficient approach for RFID network planning based on k-coverage. A k-coverage model is developed to evaluate the network performance. The Plant Growth Simulation Algorithm (PGSA) is used to optimize the RFID networks by determining the optimal adjustable parameters in...
This paper reviews the development of the curriculum in embedded system for undergraduates in the Department of Computer Science and Technology at Nanjing University (DCSTNU), presents an overview, major contents and schedule of the curriculum, discusses the experimental teaching and the case study of the course, and sums up experiences from the course teaching over the past few years. Finally, puts...
This paper analyzed the relationship between the nearest neighbour algorithm and the topology of reference tags used in LANDMARC, and proposed an optimal arrangement of reference tags. Simulation results showed that the new topology can provide better performance than the old one used in LANDMARC.
RFID technologies are getting more attention for its good performance in many application domains. Indoor location based on active RFID technologies provides an approach with a high performance to price ratio, which further expands the application domain. This paper proposes a new algorithm, which is based on analysis of LANDMARC algorithm and the general Bayesian-based algorithm. Our algorithm is...
